Today we have a post from JoAnn DeGaglia, CSW, CS. JoAnn takes us on a trek to some high-altitude vineyards, and even to the legendary land of Shangri-La.

Mountain vineyards have numerous challenges. To get a feel for this, consider the typical challenges faced by all vineyards—such as like power supply, water, and environmental impact, erosion—and multiply them. Then, add in the fact that everyone is working on the side of a steep, difficult (and maybe dangerous) site, and that the complex climate conditions affecting a vineyard site are amplified in the mountains above the fog line. On the brighter side, high elevation sites do receive much more sun with lower heat accumulation and but higher diurnal temperature fluctuations. But then there’s this: pressure from insects, birds, rodents and wild animals is much more intense in remote mountain locations. Like I said—it’s a challenge.

The highest vineyards in the world are in Argentina in the Salta region located in the Altura Maxima vineyard at 9,849 feet (and some claim it is even higher). This “extreme” vineyard produces grapes with a very think skin, resulting in rich, tannic wines with complex flavors. The first vintage of Altura Maxima wine was released in 2012 by Bodega Colomé (part of the Hess Family Estates). That wine—Colomé Altura Maxima 2012—is 100% Malbec and priced at $125. It might sound like a lot—until you realize that only 165 cases (six barrels) were produced. Bodega Colomé also grows small amounts of Torrontés, Pinot Noir, Merlot, Syrah, Sauvignon Blanc and Chardonnay in their ultra-high altitude Altura Maxima vineyard.

Here in the U.S. we look to areas like Lake County AVA (with vineyards at 2,000 to 2,400 feet), Howell Mountain (1,600 to 2,400 feet), Spring Mountain (2,000 feet), Mount Veeder (400 to 2,600 feet), Atlas Peak (1,400 to 2,600 feet), Diamond Mountain (1,200 to 2,200 feet) and Sonoma Mountain (600 to 2,400 feet) as examples of high altitude viticulture. Howell Mountain was designated as Napa Valley’s first sub AVA, and is well-known for its high-altitude Cabernet Sauvignon. The region’s volcanic ash–red clay soil, delightfully infertile, produces intense wines from small berries. In the end, the altitude and rocky, dry soil conditions create complex, tannic and concentrated wines with firm structure, incredible varietal intensity, and excellent aging properties. Cabernet Sauvignon is King of the Mountain but Cabernet Franc, Merlot, Zinfandel and Chardonnay excel as well. Who is up on Howell Mountain? Charles Krug, Cade, Cakebread, Duckhorn, Robert Foley, La Jota, and Pine Ridge—to name a few.

The world of wine evolves and changes with each passing year with more regions discovering wine, both as consumers and producers. Each of these new areas brings a new dimension to the world of wine. One in particular caught the eye of Karen MacNeil, author of The Wine Bible enough to make her declare that “the Book of Cabernet has just been rewritten.” The wine she is talking about is made in Shangri-La. Really. The wine is 2013 Ao Yun (Tibetan for Proud Cloud), produced in the Himalayas just 50 miles from the border of Burma. This area is within the Yunnan Province in the far southwest of China. The areas “Three Parallel Rivers” region (now a National Park) was made famous as the mythical Shangri-La in James Hilton’s novel Lost Horizon. The Vineyard is at 8,500 feet, and the air is so thin that fermentation doesn’t quite work like it does as we may know it. Karen MacNeil described the wine like this: “Drinking it makes you feel like you’ve been pulled down into the dark body of the earth itself. There is a sense of delicious corruption to the wine.”

Ao Youn is 90% Cabernet Sauvignon and 10% Cab Franc, bottled at 15% alcohol by volume. It should be (or will soon be) available at Sherry Lehman’s in New York and Wally’s in Los Angeles.

We can never overestimate the contributions made by the pioneers, innovators and artists of the wine making world. So get out there and open that mountain wine—climb high, my friends.

JoAnn DeGaglia, CSW, CS works at Brotherhood Winery, “America’s Oldest Winery.” In addition, she teaches wine appreciation classes at libraries all over the Hudson Valley as well as with Ned Towle at the Westchester Wine School. JoAnn’s writings may be found on Facebook on the “The Wine Lovers Journey through the World of Wine” page.

Guest Post: A Trip to the Ramona Valley AVA

.

.

Today we have a guest post from SWE member Jan Crocker. Jan has just completed our CSW Online Prep Class and is planning on taking her CSW exam next month. Wish her luck!

Jan works on the “front line” of the wine industry as a beverage steward in an upscale grocer in Southern California. Read on as Jan shares about her recent trip to the Ramona Valley AVA.

Whenever I discuss California wine with wine shoppers at work, nearly all mention Temecula, since it’s extremely familiar to oenophiles in Orange County, California. I can also count on several folks each day singing the praises of the Napa Valley (“isn’t that where the greatest wines in the world come from?” they invariably comment), as well as Paso Robles and Sonoma.

However, because I relish exploring obscure wine varieties and regions—that’s why I’ve been a wine nerd for more than 15 years, after all—I’m genuinely excited about watching the emergence of a certain young American Viticultural Area that’s fast gaining acclaim among local wine writers, professionals and judges.

.

.

With that, I’ll present the 162nd AVA in the United States: the Ramona Valley AVA.

As the third AVA in the sizable South Coast “super AVA” at 33.1 degrees north, the Ramona Valley celebrated its 10th anniversary in January 2016. The region itself is 14.5 miles long and nine and a half miles wide, and is home to 25 bonded wineries within its 89,000 acres over 139 square miles. (Note to wine nerds everywhere: the other two AVAs located within the South Coast AVA are the San Pascual Valley, founded in 1981, and the Temecula Valley, founded in 1986.)

Located about 35 miles northeast of San Diego in north-central San Diego County, the Ramona Valley is a destination famed for its balmy climate throughout the year. On the other hand, the area is no stranger to scorching summers, with daytime temperatures often above the century mark. Winters, by contrast, are brisk, with afternoons reaching the mid-60s and nights often dipping below freezing. Small wonder: Ramona is exactly 25 miles east of the Pacific Ocean, and 25 miles west of the Colorado Desert. Rainfall is moderate, with roughly 16 inches each year.

Julian, the historic burg famed for its apple pies and winters with light snow, is a mere 22 miles east of Ramona and more than 4,200 feet above sea level.  (That’s why I describe the Ramona Valley’s climate as “Mediterranean, with an asterisk.”)

.

.

Grapes thrive as a result of the Ramona Valley’s vineyard elevation: about 1,400 feet above sea level. At least two of the region’s wineries sit at nearly 2,000 feet at elevation.

Indeed, the Ramona Valley’s neighboring mountains, hills, and rocks are a force in defining the character of the region’s wines. The Cuyamaca Mountains, Mount Palomar, and Vulcan Mountain are the “high points” of the steep inclines surrounding the valley. At the western portion of the region, 2,800’ Mount Woodson does its part as a rain shadow by keeping the Pacific Ocean’s trademark fog and chill at bay.

Let’s get back to those rocks.

During each of the four visits my husband and I have made to Ramona, we’ve never failed to be wowed by the huge boulders and striking rock formations along picturesque Highway 67, the only path leading into the region. On our first trip in early 2015, I hummed “The Flintstones” theme as we approached those monster rocks, since many of them resemble Bedrock, the cartoon’s setting. The closeness of those boulders, however, kept us alert: We fervently hoped that we’d be spared one of our home state’s signature earthquakes during our drive.

.

.

Granite dominates the geological landscape, either in its original form as rocks or boulders or within the region’s loamy soil as decomposed granite. (During our four days in the region this August, we also spotted milky and rose quartz, as well as some tiny flakes of pyrite, during our “personal tours” of the 11 vineyards we visited.)

Granite’s presence also makes itself known in Ramona Valley wines: Of the 100 or so wines from the region that my husband and I have tasted in the last year and a half, all have an elegant flintiness and a backbone of minerality that’s riveting.

Southern California’s “soft chaparral” is the garrigue that shows up in Ramona Valley’s wines, reds especially. Many of my tasting notes include “sage and rosemary,” so it’s no mystery  to find that flora in the region’s natural landscape, along with wild oak, toyon, chamise and numerous species of cacti.

Local winemakers embrace the Ramona Valley’s terroir, planting varieties that develop deep flavors as they echo the area’s climate, soil types and ever-present breezes. John Saunders, the proprietor/vineyard manager/winemaker at Poppaea Winery, mentioned that a few local enologists have identified “at least 11 different microclimates” within the 139-square-foot valley, so the range of wine grapes compatible to those potential “mini-AVAs” is broad – and speaks to the stunning diversity of the region.

Red varieties flourish, especially those with their roots (no pun intended) in France, Italy and Spain. To that point, two wineries – Poppaea Winery and Principe de Tricase – are planted to white and red varieties spanning the length of Italy. Not surprisingly, Tempranillo craves the region’s sunshine and wide diurnal swings.

.

.

Other growers and winemakers opt for Rhone varietals, as Syrah, Grenache, Mourvedre and Viognier flourish in similar conditions in the Ramona Valley: rocky and barren soils, ample sunshine and a steady, moderating breeze, albeit without the destructiveness of the mistral. Woof ‘n Rose Winery was planted to Grenache Noir in 2004, with consultation from fifth-generation winemaker Marc Perrin of Château de Beaucastel—as well as Grenache rootstock from the French vineyard. Ramona Syrahs showcase a brooding, deep style much like their Cornas or St. Joseph cousins; those from Ramona Ranch Winery and Eagles Nest both offer elegant, haunting scents and flavors with earthiness and garrigue.

Wine fans searching for varieties above and beyond their tried-and-true classics will have a field day with offerings from the region. During our four days in the Ramona Valley, my husband and I visited 11 of the region’s 25 wineries, tasted 82 current releases – and had the good fortune to try six varieties we’d never before had the opportunity to taste: Alicante Bouschet, Refosco, Aleatico, Fiano, Sangrantino and Bolizao. Tannat, the pride of Madiran, is a featured variety at Ramona Ranch Winery, one of the wines my husband and I enjoyed thoroughly.

.

.

There’s no wonder why proprietors Marilyn and Steven Kahle at Woof ‘n Rose take pride in their Alicante Bouschet, the gorgeous teinturier: It’s generous, opulent, complex and undeniably enjoyable – and, my husband and I thought, a varietal that red fans would love if they tried it.

Speaking of Refosco: When was the last time we wine fans tasted one other than from their original northern Italian homes of Friuli or Trentino? Mike Kopp, proprietor/vineyard manager/winemaker at Kohill, offered us a barrel tasting of his signature Refosco, which nearly brought us to our knees.

Although heat-loving red varieties have a joyous home in the Ramona Valley, many whites do as well. Wine fans who enjoy their Chardonnays most when they’re flinty and zesty will appreciate the mineral influence of Mount Woodson and the nearby Cuyamacas; the elegant Chards featured at Lenora and Eagles Nest showcase that sculpted, sinewy quality as a counterpart to the variety’s richness.

It’s impossible to overlook how well Mother Nature took care of us during our four days during the first week of August. During each of our visits to the 11 wineries, every proprietor, winemaker and vineyard manager gushed over the gorgeous weather that week—sunny, of course, but with soft breezes. It’s usually blazing hot, “about 100 degrees at this time of year,” our winery hosts pointed out. “But it’s only in the high eighties. Isn’t it beautiful?”

We couldn’t have agreed more. And the Ramona Valley AVA’s future looks equally gorgeous – with the distinct likelihood that California wine fans will soon discover its current excellence and stunning future.

The Numbers, in Perspective – All about that Yield

...

While math might not have been your favorite subject in school, you most likely find the need to use math at least sometimes, even in the study of wine! 

Last week, Mark Rashap, CWE gave us some excellent explanations of some wine-related mathematical conversions as they pertain to area, volume, and weight. In this second installment of “The Numbers, in Perspective,” Mark will tell explain the mathematical calculation behind yields. Hold on, this won’t hurt a bit….

All about that yield: how much wine can that vineyard produce? Sometimes, it is all about yield. As every good wine student knows, yield is where we start getting into a factor of quality.  There is some evidence that the lower the yield, the higher the quality, within a certain range—and that’s a great debate for another time and place. As for the math, pure and simple, in the United States, we most often refer to vineyard yield in terms of tons per acre. In Europe, it is most often expressed as hectoliters per hectare.  As tons=weight and hectoliters=volume, it is not possible to come up with an exact conversion. However, we can find an equivalency to give us a way of comparing the two systems.

Consider this: Cornell teaches that 1 ton of grapes will yield 150 gallons of wine, or 5.67 hl.  If we consider that is per acre and convert to hectares, we have our factor: 1 ton/acre = 14 hl/ha

...

Using this factor, we can have some fun comparing yields per region.  I always think of 4 tons/acre as entry into the quality realm of wine. According to Robert Craig, this is the approximate yield of the valley floor AVAs of Napa. Using our conversion factor, we can calculate that 4 tons/acre = 56 hl/ha. Considering that 55 hl/ha  is the maximum  yield for Bordeaux AOC, and the maximum for Bordeaux Superior AOC is 50 hl/ha, we can see that the two areas have very similar yields.

In the mountainous vineyards of Napa, yield is closer to 2.5 tons/ acre, an equivalent of 35 hl/ha.  On the extremes, I’ve seen yields as high as 10 tons/acre (140 hl/ha) in the Central Valleys of California and Chile, and yields as low as 5 hl/ha in the Priorat which equates to 1/3 of a ton per acre!

Here are a few more permitted yields, just for fun:

  • Bourgogne AOC (white): 68 hl/ha
  • Bourgogne AOC (red): 60 hl/ha
  • Corton-Charlemagne (Burgundy Grand Cru) AOC (white): 58 hl/ha
  • Montrachet (Burgundy Grand Cru) AOC (white): 48 hl/ha
  • Corton (Burgundy Grand Cru) AOC (white): 48 hl/ha
  • La Romanée (Burgundy Grand Cru) AOC (red): 38 hl/ha
  • Corton (Burgundy Grand Cru) AOC (red): 35 hl/ha
  • Alsace AOC (white): 80 hl/ha
  • Alsace AOC (red): 60 hl/ha
  • Sommerberg (Alsace Grand Cru) AOC (white): 55 hl/ha
  • Beaujolais AOC (red) 60 hl/ha
  • Morgon (Beaujolais Cru) AOC (red) 56 hl/ha

Sometimes, it truly is…all about that yield!

The Numbers, in Perspective

Today we have a guest post by Mark Rashap, CWE. Read on as Mark gives us some advice about the numbers…

...

One of the most challenging and rewarding aspects of being a wine professional is that we must master a multitude of academic fields.  Often, in addition to “wine expert,” educator, and salesperson, we play the role of chemist, biologist, linguist, geologist, and historian. Other roles that we have to assume on a fairly regular basis include mathematician and statistician—and this does not sit well with many people!

In light of this situation, I thought it would be fun and handy to compile some of the more useful conversions that every wine professional should know and understand.  What follows includes some strict mathematical conversions, some industry averages, and some hints for their interpretation.

How big is that vineyard? One of the first steps in understanding a wine producer, estate or region is to understand just how big the vineyards are, and how they compare with others. In order to do this, it is imperative to know the following: 1 Hectare = 2.5 acre (it’s actually 2.47, but we can’t do that in our head).  To convert hectares to acres, the quick math is to double the number, then add half of the original number.  Paulliac, at an average of 1,200 Ha equates to about 3,000 acres.

  • Try it yourself: If there are 800 ha in Pomerol, and 2,000 acres in Walla Walla, which is bigger?  (The answer: they are about the same!)
...

How much wine is in that container? Thankfully, most people are used to measuring wine in liters…particularly 750 ml. However, sometimes we need to deal with larger numbers, especially in terms of barrels, shipments, or tax reports! Wine professionals should keep in mind that that 1 gallon = 3.785 L, and the traditional European wine barrel (barrique) is 60 Gal or about 225 L. This equates to 300 bottles of the standard 750 ml size.

How much do those grapes weigh? In the US, we still use pounds to measure the weight of grapes coming from the vineyard.  Much of the rest of the world uses kilograms, so we should know that 1 Kilogram = 2.2 pounds (and 1 pound = 0.45 kg). If we are talking about a truckload, it will be useful to know that there are 2,000 pounds to the ton. A metric ton is 1,000 kilograms, which equals 2,200 pounds—otherwise known as a metric ton or tonne.

I am sure that is enough calculation for now. However, keep an eye on the blog – we’ll follow up with a look at calculating yield, temperature, and rainfall—in perspective.

Searching for the Origins of Fermented Beverages

Today we have a guest post written by David Glancy, MS, CSS, CWE. David dives into the ancient origins of wine and beer, and tells us about an upcoming event at his San Francisco Wine School. Read on!

Archaeologists have never been so cool. Dr. Pat (Patrick McGovern) is the Scientific Director of the Biomolecular Archaeology Project for Cuisine, Fermented Beverages, and Health at the University of Pennsylvania Museum in Philadelphia. He is often referred to as the world’s leading archeologist of fermented beverage, a career path my high school counselor failed to mention. When he’s not in his office at the University of Pennsylvania he is often wandering the Caucasus from Russia to the Middle East, or exploring a tomb in Egypt or a new dig in some remote mountain in China. And between all of these places he has found the oldest scientifically verified fermented beverage and wine (for now). Who knows what else he might find as he keeps digging.

That beer is old! In 2004 Dr. Pat and his colleagues documented the oldest fermented beverage. They carbon dated and DNA tested scrapings from pottery shards. It turns out that China’s thirst for beer is not new (#1 beer consuming nation). This beer dated back to 7,000 BC and was found at a Neolithic Chinese site called Jiahu. It is in southwestern Henan Province, China, on the east slopes of Fuliu Mountain. It was a grog made from rice, grapes and/or hawthorn fruit, and honey. Sam Calagione, brewer/owner of Dogfish Head Brewery in Delaware has made an interpretation of this ancient brew with Dr. Pat as a consultant.

...

The birthplace of wine made from grapes seems to be from the Caucasus. The Greater Caucasus stretch from Russia through the Georgian Republic to Armenia and Azerbaijan with stops in between. The Lesser Caucasus include Turkey and Iran, but ancient winemaking seemingly wandered from there to the Mediterranean with noted production in modern day Iraq, Lebanon, Israel, Jordan and Egypt.

Dr. Pat and his colleagues found the oldest wine, too. Once again, they were digging, scraping and lab testing. The wine residue they found dated back to 5,400 BC and was found at another Neolithic site (Hajji Firuz) in the northwestern Zagros Mountains of Iran. Six jars of the same shape, each with a volume of about 9 liters, were found lined up and set into the floor of a “kitchen” in a square mudbrick house.

Here is an overview of several of the wine producing countries of the Caucasus and Middle East.

  • An Armenian Wine Renaissance is under way. There are over 100 grape varieties being grown today in Ararat, Armavir and other regions of Armenia but much attention is being paid to an ancient variety, Areni Noir. Grape growing and winemaking were minimal after Armenia’s independence from the former Soviet Union, but today small producers are breathing new life into the industry from Armenian nationals to flying winemakers like Paul Hobbs.
  • Georgia has over 500 grape varieties being grown today and the industry is growing. By far the most widely planted variety is Rkatsiteli, a white grape. There are also several variations of a white grape called Mtsvane. The leading red grape is Saperavi. Wine is made in Kakheti and many other regions of Georgia.
  • Lebanon has continued to make wine despite many years of warfare. Winemaking has been practiced in the Bekaa Valley for over 6,000 years. There are roughly 40 wineries and Chateau Musar is one of the most famous. Many international grape varieties are grown here along with the local Obaideh and Merwah.
The Golan Heights Winery; Katzrin, Israel

  • Israel also has produced wine for thousands of years though most of their 100+ wineries started in the last few decades. The five official wine regions are Galilee-Golan, Shomron, Samson, Judean Hills and  Negev. Production has shifted from white to red wine from many varieties including Bordeaux and Tuscan grapes.
  • Palestine is producing wine against all odds. There is minimal production despite thousands of years of history of growing grapes here. The few vineyards are in the area around Bethlehem and Hebron in Palestinian territories between Israel and Jordan. Baladi, Dabouki, Jandali and Hamdani grapes are the main focus.
  • Turkey largely focuses on indigenous grapes. Sultaniye, Öküzgözü and Bo€azkere grapes are the most widely grown but Shiraz is also widely planted. There are over 1 million acres of vineyards in this large country but a good deal produces fresh and dried fruit, not just wine. There are over 600 unique grape varieties here and the majority of the vineyards are in the region of Thrace, along the Sea of Marmara, near Greece and Bulgaria.

All of these topics and more will be covered in depth at the upcoming Cradle of Wine Civilization Event at the San Francisco Wine School, to be held in South San Francisco on March 13. The day’s events will include 4 seminars, 14 panelists and speakers from around the world, wines from Armenia, Egypt, Georgia, Israel, Jordan, Lebanon, Palestine, and Turkey; a multi-cultural lunch with the winemakers, walk-around grand tasting, and an ancient brews happy hour.

Guest Blog: Exploring Germany’s Mittelrhein

.....

…..

Today we have a guest blog from Lucia Volk, CSW, reporting from Germany, where she is visiting the lesser known wine regions.

If you are a fan of Riesling, you undoubtedly know the Rheingau. The Rheingau is home to  Germany’s prestigious, over 1,000-year-old Schloß Johannisberg, where late harvest (Spätlese) was allegedly invented. You probably also know the neighboring Rheinhessen, Germany’s largest and most productive wine area.

Next to those Riesling wine super-powers, the Mittelrhein region, which the German Wine Institute ranks second-to-last by size – only Hessische Bergstrasse is smaller  has to struggle to be noticed. It does not help that regional wine advertisement budgets in Germany are pegged to acres cultivated, or that the Mittelrhein extends into the jurisdiction of two German states, Rhineland Palatinate and North Rhine Westphalia, that do not always agree politically. Depending on the size of the harvest, the Mittlerhein region contributes somewhere between 0.3 and 0.5% to Germany’s wine total. Let’s face it: even within Germany, Mittelrhein Riesling is an insider wine.

Castle Reichenstein

Castle Reichenstein

Most of this lesser-known region – almost 85% – consists of terraced slate slopes that require manual labor, and yields are low. Because of the extra labor hours required per acre cultivated, it can be difficult to find a successor for a Mittelrhein winery after a vintner retires. The overall area under wine has fallen from 1,800 acres in the early 1970s to approximately 1,100 now.

Fortunately for wine lovers, the numbers are beginning to hold steady.  About 70% of grapes planted are Riesling, another 10% go to Müller-Thurgau and Kerner combined, 10% to Pinot Noir, and the remaining 10% to Pinot Gris, Pinot Blanc, Dornfelder, Portugieser and others. In other words, the Mittelrhein is primarily a place for white wine lovers, although Pinot Noir acreage is on the rise.

Historically, the Rhine river separated the Roman Empire from the realm of the Gauls. The Romans planted the first vines in the region, and they built the first fortifications, a tradition that was adopted by German nobility in the Middle Ages. Fortresses, castles and and customs towers – the Rhine river was an important trading route – line the hilltops.  These historical remains – many carefully restored, others in ruins – create the backdrop for the “Romantic Rhine.“ Tourists can book river boat trips, with scheduled stops for guided castle tours and subsequent wine tastings. Because of its cultural and historical significance, the Mittelrhein valley was designated a UNESCO world heritage site in 2002 , thirteen years before Champagne and Burgundy received similar badges of distinction.

The Rhine River is responsible for the favorable growing conditions in most of Germany’s northern latitude vineyards. Already at its source, close to Lake Constance, grapes are under cultivation, and if you follow the stream you will be able to taste, in succession, Baden, Pfalz, Rheinhessen, and Rheingau wines, before you reach the wine growing limit (for now) at the Mittelrhein. Mild winters allow for early buds in spring and extended sunshine permits ripening into October, resulting in unique aromas that are difficult to replicate in Riesling vineyards elsewhere.

The picturesque Mittelrhein geography was created at the end of the Devonian Age – 360 million years ago – when what used to be the bottom of the prehistoric ocean rose up all at once, and the water subsequently had to cut a path through the rocks. The Anbaugebiet  Mittelrhein is divided into two districts (Bereiche): the larger Loreley** between Bingen and Koblenz in Rhineland Palatinate, characterized by slate and greywacke soils, and the smaller Siebengebirge between Neuwied and Bonn in North Rhine Westphalia, which also contains volcanic rock and loess.

Eleven larger sites (Großlagen) are divided up into 111 vineyard sites (Einzellagen). The soil is nutrient-poor and well-drained, so roots go deep.  With the exception of irrigating freshly planted vines, most Mittelrhein winemakers dry-farm, although irregular rainfall over the last decade has some winemakers worry about the increasing stress levels of their vines. A quarter of the harvest turns to Prädikatswein, and the rest to Qualitätswein.  Deutscher Wein or Landwein production is negligible.

You can still find cooperatives that produce Mittelrhein wines, a tradition that dates back to the late 1800s, when phylloxera devastated most of the region’s vineyards.  But more commonly, you now find small family wineries that trace grape production back for several generation, as well as new ventures of enterprising young winemakers.

For instance, Peter Jost and his daughter Cecilia today run the Toni Jost winery, named after Cecilia’s grandfather.  Their prized Einzellage is the Bacharacher Hahn, which overlooks the Rhine outside the town of Bacharach. The word Hahn translates to rooster, which decorates the Jost label, but the vineyard’s name probably stems from Hain (=grove). Founding members of the VDP – Verein Deutscher Prädikatsweingüter – their estate comprises 40 acres, not all of them on the Mittelrhein, and they produce almost 100,000 bottles a year, predominantly Riesling.

Following VDP regulations, their vineyard sites are ranked according to their potential for excellent, terroir-specific wine. Additionally, Cecilia recently introduced Devon-S (S for Schiefer=slate) Riesling that brings white flowers to the nose, offers stone fruit in the glass, and finishes with pronounced Mittelrhein minerality. If you do not know what rock tastes like, Devon-S will take you there.

In the middle of the Mittelrhein, Florian Weingart makes his wines in premium Einzellagen between Boppard and Spay, especially Engelstein  and Ohlenberg. Dedicated to the local soil, he searched historical records for documentation of former vineyard sites – areas that had gone wild – and spared no effort to rehabilitate the most promising among them.

On 11 acres, he produces around 45,000 bottles of wine in a regular year.  In 2014, when late rains and pests ruined much of the Riesling crop, it was closer to 30,000. He coaxes each of his wines to develop his own character, using ambient yeast, if possible, and he allows them to finish fermenting early, if that is what the yeast decides to do. If his wine cannot obtain a certain (legal) quality level, because of it, he will rename (and effectively declassify) it. A philosopher in his spare time, he has started writing a Modern Ethics of Wine based on his “less is more“ winemaking principles.

The town of Leutesdorf in the Siebengebirge Bereich of the Mittelrhein claims to be the last big bastion at the northern Riesling frontier. Here, wine technician Marc Josten and enologist Torsten Klein acquired vineyards in the famed Einzellage Gartenlay, where they produce both Riesling, and, in a bold move, Sauvignon Blanc. Their first wines were introduced in 2012, when they were still a garage winery in Remagen, operating out of rented space.

Lucia 4For their Sauvignon Blanc and some of their Riesling, they employ traditional, large oak barrels. While Riesling, Pinot Gris, and Sauvignon Blanc comprise 75% of their total production, they also grow 25% Pinot Noir in vineyards in the neighboring Ahr region, a red-wine stronghold. Altogether, they work about 14 acres. They focus exclusively on dry wines, and promote food pairing events jointly with local restaurateurs. Josten & Klein were the prestigious Gault&Millau Wineguide’s 2013 Discovery of the Year.

A relatively recent initiative specific to the region is the Mittelrhein-Riesling Charta. Participating winemakers agreed on a unified front label for their bottles, which shows the Charta grape symbol, the names of one of the categories – Handstreich, Felsenspiel and Meisterstück – and the two words: Mittelrhein and Riesling. Winery-specific information can be found on the back label. If the categories remind you of an Austrian classification system, you are correct. The Mittelrhein group consulted with Wachau wine producers who use similar designations and production guidelines for a variety of their wines.

...

Rather than focus on terroir (i.e. Bacharacher Hahn) or ripeness category (i.e. Kabinett or Spätlese), the Mittelrhein-Riesling Charta promotes flavor profiles: light, easy-to-drink, food-friendly (= Handstreich, metaphor for “spontaneous, quick action”); medium, balanced, expressive, good on its own or with a meal (=Felsenspiel, “rock play”); or full-bodied, quite dry, deeply aromatic and lingering (=Meisterstück, “master piece”). With this approach, the Charta members avoid the traditional sweet, medium-dry, or dry labels that suggest sugar (and alcohol) levels matter most in wine. Think of the Charta as a new generation of Mittelrhein winemakers jointly re-thinking and re-branding what they think is important about a segment of their Riesling production. All of them continue to offer traditionally labeled bottles.

Next to well-known German Riesling exporters Leitz, Dönhoff, Dr. Loosen, Deinhard/Von Winning, or Schloss Johannisberg, winemakers along the UNESCO world heritage valley have an undeniable underdog status. You will not find Mittelrhein wine in many stores in the United States, but what wine drinker does not like the occasional treasure hunt for a rare bottle? For an authentic Mittelrhein Riesling experience, book a boat trip down the Romantic Rhine, open a bottle on the sun deck, and count the castles as you go by.

**The name for the Bereich Loreley derives from a famous promontory on the Rhine river near St. Goarshausen. Because of the narrow fairway, accidents were not infrequent before modern navigation technology. Poet Heinrich Heine turned the site of captains’ misfortune into a metaphor for unrequited love: the beautiful, blond Loreley perched on her rock, singing her siren’s song, while forever staying out of reach, caused men to lose their bearings, if not their lives.  In English, it sounds like this.

Guest Post: On the Wines of Saxony

The city of Dresden, on the Elbe River

The city of Dresden, on the Elbe River

Today we have a guest post from Lucia Volk, CSW. Lucia shares with us her interest in and discovery of the wines of Saxony!

If you have had your fill of Rieslings and Pinots from the Mosel, Rheingau, Rheinhessen and Pfalz – and find yourself in the mood for a different kind of German wine – let me draw your attention east, to the re-emerging wine region of Saxony!

Upstream and downstream from the city of Dresden, with its many baroque palaces, churches, cobble stone streets, and numerous museums, are about 1,100 acres of vineyards. These vineyards are part of the Sachsen region, which ranks 11th in size among Germany’s thirteen wine regions. The Elbe River and the hills along both sides helps create the weather and soil conditions that make wine growing possible at 51 degrees latitude. Officially, the wine region of Saxony stretches from Pillnitz in the south to Diesbar-­‐Seußlitz in the north, along roughly 60 miles of Elbe, which then continues on to Hamburg and the North Sea.

Saxony’s glorious history involves a late 17th century duke-turned-king by the name of August the Strong, whose claim to fame (among many other things) is breaking horseshoes with his bare hands. He loved the good life (when he wasn’t going to war), and sponsored palaces with gardens, plazas and fountains; and filled museums with art. He hosted lavish parties and, of course, he needed wine. The historical record shows that within decades of his reign, 4,000 acres of vines were under cultivation by up to 8,000 wine makers – vastly more than Saxony’s current holdings.

The 1888 phylloxera infestation did much to reduce the vineyard acreage – two world wars, real estate development, and the state-planned economy of the German Democratic Republic did the rest. 1990, the year of Germany’s unification, is often considered as the starting point of Saxony’s wine revival. The eastern-most German wine region holds much promise with many young winemakers eager to catch up to the much more established wine regions in the southwest of Germany.

Wine producers along the Elbe currently come in three kinds: privately owned wineries, which include the prestigious – and Saxony’s oldest – Schloss Proschwitz as well as small innovators with 5-15 acres of each; the state-owned winery in historic Schloss Wackerbarth with nearly 250 acres and 100 employees; and the Wine Cooperative Meissen (Winzergenossenschaft Meissen) with 360 hectares and 1,500 participating part-time growers. The production volume varies accordingly, from 8,000 to 600,000 to one million bottles a year. Due to steep slopes and challenging growing conditions – late frosts in spring time, dry summers, and cold and wet harvest seasons – none of the producers above can expect a high yield, regardless of their vineyard locations or the grape varietals. If necessary (and feasible in terms of staffing) vineyards are harvested two or three times to give more grapes the opportunity to ripen fully.

Grapes grown in Saxony are mostly white (85%):  Müller-Thurgau, Riesling, Pinot Blanc, Pinot Gris, and Traminer are the most widely planted; Bacchus, Muscat, and some Chardonnay are minor white grapes. Pinot Noir and Dornfelder lead the reds;  Portugieser, Regent, and Schwarzrieslings can be found as well. A large part of the production is made into sparkling wine, following various production methods. Single-variety still wines come in the usual choices from dry to sweet, from Landwein to Trockenbeerenauslese. Cuvees are also offered, for instance, Traminer along with Riesling, or Pinot Noir plus some Portugieser. Premier vineyards are Seußlitzer Schlossweinberg, Proschwitzer Katzensprung und Radebeuler Goldener Wagen.

Schloss Proschwitz is Saxony’s oldest private winery, with its own castle and artistocratic owner Prinz von der Lippe.  A renowned restaurant and upscale bed and breakfast invite guests to stay for a while. Still wines, sparklers, and liqueurs are on the shelves, each category in dazzling varieties, from a 13 Euro bottle of Müller Thurgau to a 58 Euro bottle of Pinot Noir. Many of its vineyards were originally owned by the church, most of the wine was made for mass. The church lost ownership over many of its estates to secular, liberal movements in Germany; later, the von der Lippe family lost its vineyards to state socialism, and only in 1990 did they begin to buy back what the family used to own. The winemaker hired to bring Schloss Proschwitz back to its old prominence was Geisenheim graduate Martin Schwarz, who recently started his own “wine manufacture,” as he calls it. In his able hands, Saxon grapes turned to refreshingly dry, aromatic, earthy wines. If you never had Müller-Thurgau you liked, you might find one here.

Erlebnisweingut  Schloss  Wackerbarth  translates  to  “adventure  vineyard”  on Wackerbarth’s website. It is a winery that offers a full schedule of paired food, music, dance and theater events throughout the entire year, Christmas and New Year’s included. Guests can walk around expansive grounds with a historic palace and brand new restaurant, wine bar, cellar, and shop.   With a seasonally adjusted staff of   plus/minus 100, Schloss Wackerbarth bottles up to 600,000 bottles a year, the majority sparkling wine.  On its premises, only traditional method, hand-riddled sparklers are made, a process visitors can witness from the tasting room overlooking the storage cellar facility.   Another Geisenheim graduate, Jürgen Aumüller, took charge in 2002, dividing his attention between his cuvees (mostly for sparkling wine, but also for still) and single-variety wines.   The state of Saxony   owns the winery, and with the help of substantial investment of the Saxony Development Bank in the early 2000s; Schloss Wackerbarth now represents the new way of doing wine business on the Elbe river.

.

Founded in 1938 as Saxon Wine Cooperative (Sächsische Weinbaugenossenschaft), renamed the Wine Cooperative Meissen in 1955, and currently led by a woman winemaker, Natalie Weich, the cooperative produces half of Saxony’s wine, a million bottles per year on average. The vineyard holdings span the entire Elbe region, from Pillnitz to Diesbar-­‐Seußlitz. You can find an interactive map (in German) on the cooperative’s website. Cooperative production historically allowed people to share production facilities and spread production risks. Grapes were an additional source of income, and under state socialism, an additional source of goods to trade. Grape quality was historically sacrificed to grape quantity, as producers were paid by weight they delivered. Those days are mostly days of the past, as producers realize that they need to compete with national and international standards. Wines from the cooperative regularly win gold, silver and bronze medals in the annual Federal German Wine Awards (DLG -­‐-­‐ Deutsche Landwirtschafts-­ Gesellschaft).

The natural beauty and regional history of the Elbe valley are already reasons for a visit. If you enjoy hiking and biking, you will be able to fill your vacation with memorable activities – but be sure and leave time to schedule wine tastings throughout. And you will want to leave space in your suitcases to bring some home!

Guest Post: On the Wines of Colorado

Vineyards in Grand Junction, Colorado

Vineyards in Grand Junction, Colorado

Today we have a guest post from Justin Gilman, CSW, who tells us about the blossoming wine industry in his adopted state.

Colorado’s wine industry began back in 1890 when then-Governor George Crawford planted roughly 60 acres of vines in the Grand Valley near Palisade. Just over a decade later, there were over a thousand Colorado farms involved in grape growing.

These days, the majority of Colorado’s wine production is focused in the West-Central part of the state, near the town of Grand Junction. Colorado currently boasts two AVAs: Grand Valley and West Elks. About 75% of the state’s one hundred-plus wineries are located in the Grand Valley AVA while the remaining 25% are in the West Elks AVA.  Other growing regions include McElmo Canyon, Montezuma County, South Grand Mesa, Freemont County, Olathe County, and Montrose County.

Colorado’s continental climate coupled with its famous high elevation means that grapes grown here receive a tremendous amount of sunlight with minimal cloud cover. However, the grapes also benefit from an excellent diurnal temperature variation – meaning the sunshine and heat help to unlock sugars during the day; and the exceptionally low temperatures help to retain acidity at night.

.

.

Colorado’s elevation, foliage and mountain ranges have been compared to that of Northern Italy’s Alto-Adige region. With the highest wine growing elevation in North America, (Grand Valley 4,000-4,500 ft. and West Elks up to 7,000 ft.) these chalky and loam soils see as many degree-in days as Napa, Tuscany and Bordeaux in a shorter period of time.

The grape varieties grown here are on par with other wineries across the country. Cabernet Sauvignon, Merlot, Chardonnay and Moscato are staples, with some experimentation of blends between wineries. Rhône varieties do particularly well in Grand Valley, and Tempranillo is showing great promise in the West Elks AVA.

As in any wine country, Colorado wineries offer a wide range of products. Taking advantage of the sunny skies and over 300 days of yearly sunshine, some Colorado wineries create consumer-friendly wines leaning on slightly higher sugar levels. Softer Cabernets, Chardonnay/Moscato blends and plenty of sweet fruit wine options like that of Carlson Vineyards Cherry & Peach wine to St. Kathryn’s “Apple Blossom” and “Golden Pear” are popular wines, known for being friendly to a beginner’s palate.

.

.

Some of the best wines in the state are produced by Ruby Trust Cellars of the Castle Pines area. Ruby Trust Cellars, led by owner Ray Bruening and winemaker Braden Dodds have produce wines with rough-and-ready names such as “Gunslinger”, “Fortune Seeker” and their recent addition “Horse Thief”. Located roughly 20 miles South of Denver, Ruby Trust puts out a handful of limited production blends and single varietal wines that have caught the eye of some well-known critics. Sourcing fruit from growers in Grand Junction, Ray and Braden uphold the highest integrity when creating their wines. Retailing just over $30 a bottle, their wines are individually numbered with labels reminiscent of the historical mining era of Colorado. Ruby Trust is considered amongst Colorado’s best, found in selected Aspen and Vail restaurants and resorts, as well as specialty wine shops throughout the Denver area.

Colorado has also embraced the idea of the “urban winery,” including Bonaquisti Wines, located in Denver’s Sunnyside neighborhood. Bonaquisti Wines proudly declare themselves to be procurers of “Wine for the People!” With wine in kegs, refillable growlers, and live music every Friday night, it seems like they are living up to their motto quite well.

One of the most intriguing wineries in Colorado is undoubtedly the Infinite Monkey Theorem. (The name is derived from the theory that a monkey striking typewriter keys for an infinite amount of time will, eventually, create the works of Shakespeare.) Founded by Ben Parsons, the winery was originally housed in a graffiti-covered Quonset hut. While the business is now housed in a 20,000-square foot warehouse, they still tend to do things (shall we say) a bit differently, and feature such items as wine in cans and a “bottles and bacon” gift pack.

Yearly, Colorado’s best wines are judged at the Governor’s Cup in Denver, and an alternate event with growing popularity, the Denver International Wine Competition. The Governor’s Cup focuses on Colorado Wines, presented by the Colorado Wine Board, to discover the “Best of the Best” in Colorado, while the Denver International Wine Competition welcomes any wine with the potential of being distributed in Colorado. Previous winners of the 2014 Governor’s Cup include Canyon Wind Cellars 2012 Petit Verdot, Grand Valley AVA, $30 and Boulder Creek Winery, Boulder, 2013 Riesling, Colorado, $16.  The 2015 top scorers include Bonacquisti Wine Company – 2013 Malbec, (American) and Bookcliff Vineyards 2014 Viognier, Grand Valley AVA.

The Colorado wine industry is consumer friendly and each year is continuing to grow by leaps and bounds, striving to be traditionally focused. For the future, the industry is focused on minimizing blends, gradually creating more structure- driven wines, and slowly educating the consumer palate – a noteworthy goal in a state known for its beer consumption. Given the terroir, and talent, and these noted goals, the future looks bright for the Colorado wine industry.

Big Controversy over Little Rocks at the TTB

.

.

Today we have a guest blog from Brenda Audino, CWE, who brings us up-to-date on the latest controversy at the TTB!

This is a follow-up to the blog “Oregon, Washington, and the AVA Shuffle: It’s Complicated”.  As noted, the newly created appellation “The Rocks of Milton-Freewater” created some controversy. The controversy is not about the validity of the appellation itself – just about everyone agrees that “The Rocks” is a unique region. The controversy arises in who amongst the wineries will ultimately be able to use this new AVA on their wine labels.

Here is a refresher regarding the Rocks of Milton-Freewater AVA: it is a sub-AVA nested within the larger multi-state Walla Walla Valley AVA, which is also nested within the much larger multi-state Columbia Valley AVA.  The Rocks of Milton-Freewater AVA resides solely within the borders of Oregon, while the larger multi-state AVAs are predominately in Washington State while crossing over the border into Oregon.  The controversy with this new AVA is that since it is entirely within the borders of Oregon, wineries must also be in Oregon in order to use the AVA on a wine label.  Most wineries who call the Walla Walla AVA home are located in the state of Washington.  This means that even if the winery owns vineyards or sources fruit in The Rocks of Milton-Freewater they will not able to utilize that The Rocks of Milton-Freewater AVA on their labels

The comments received by the TTB during the “open comment” period concerning this inability to use The Rocks of Milton-Freewater AVA were deemed valid by the Alcohol and Tobacco Tax and Trade Bureau (TTB) and worthy of consideration.  This means that the TTB acknowledges that the current regulations would require wine that is fully finished in Washington and made primarily from grapes grown within The Rocks District of Milton-Freewater AVA to be labeled with the less specific “Walla Walla Valley” or “Columbia Valley” or “Oregon” appellations of origin.

.

On February 9, 2015 the TTB created a new proposed rule to address these specific concerns that were raised regarding this new AVA.  This new proposed rule is titled “Use of American Viticulture Area Names as Appellations of Origin on Wine Labels”.

The TTB proposes to amend its regulations to permit the use of American Viticulture area names as appellation of origin on labels for wines that would otherwise quality for the use of the AVA name except the wines have been fully finished in the state adjacent to the state in which the viticultural area is located rather than the state in which the labeled viticultural area is located.

The TTB goes on to note that the purpose of an AVA is to provide consumers with additional information on wines they may purchase by allowing vintners to describe more accurately the origin of the grapes used in the wine.

The TTB does not believe this new ruling will cause consumer confusion since multi-state AVAs allow the wine to be finished in either state.  They believe consumers are aware that appellation of origin is a statement of the origin of grapes used to make the wine and it would not be confusing or misleading if a single state AVA were finished in an adjacent state.

I don’t know if the TTB had any idea of the amount of comments this “fix” to the AVA system would generate, but this proposal opened up an entire flood of opposing views.

During the comment phase there were a total of 41 submissions. Out of these 41 comments there were 16 “For”, 18 “Opposed”, 6 “recommended a change to the proposal” and 1 “suggested an extension of the comment period”.

The “For” comments ranged from “providing consumers better knowledge of the origin of grapes”, “fair competition and accurately reflect origin of wines”, “increase business opportunities”, “where grapes are grown is more important than where wine is finished” and “grape shortages in adjacent states”.

.

.

The “Opposed” comments ranged from “confusion for consumers”, “support for local economy”, “the term ‘adjacent state’ is too broad, “undermines state labeling laws”, “large business will transport more grapes to take advantage of AVA names” and “creates deceptive labeling”.

The comments that “recommended a change to the proposal” felt that the following wording on the proposal –“wines have been fully finished in the state adjacent to the state in which the viticultural area is located rather than the state in which the labeled viticultural area is located” – is too broad and encompassing.  This, the commenter believes, has the potential to dilute current AVA status by transporting grapes across long distances.  They recommended a change to the proposal to include “Wines finished in either state of a multi-state AVA can utilize any Sub-AVA that is nested within this multi-state AVA.”  This would enable the wineries of Washington to utilize The Rocks of Milton-Freewater AVA, but not Willamette Valley AVA.  This in effect would narrow the scope and alleviate many of the concerns raised by the commenters.

Unfortunately, I don’t have an end to this story.  The comment period is now closed and the final ruling by TTB won’t be released until April 2016.  For now though, if you want to find a wine from The Rocks of Milton-Freewater, you will need to search for an Oregon winery.

Flash Détente: Making Red Wine Redder

Brenda flash 2Today we have a guest post from Brenda Audino, CWE. Brenda tells us about her brush with Flash Détente – very interesting!

I recently tasted a modest (read inexpensive) wine that had a bright purple hue and Jolly Rancher fruit aromas.  I enquired whether the wine had undergone Carbonic Maceration as it seemed to fit that profile.  It was explained to me that although the results are similar, this particular wine was produced using Flash Détente technology.  Being ever curious, I wondered what is Flash Détente; when, why and how is it used in the wine production.

To explain Flash Détente, we need to understand that one of the principal goals in producing red wine is the extraction of color and flavor from the skins.  This extraction is usually achieved by a combination of maceration and fermentation. Here is a review of three popular means for extraction including the new (to me) Flash Détente.

Classic maceration is achieved at low temperatures of 24-32°C (75-90°F) requiring extended contact between the juice and grape skins.  The fermentation process, while producing alcohol, also extracts the polyphenols from the skins.  One of the byproducts of fermentation is the release of CO2 which raises the skins to the surface forming a floating cap.  This floating cap is subject to acetic bacteria as well as other contaminates and, if left exposed to the air, can turn the entire batch into vinegar.  A floating cap also does nothing to extract further color and flavors into the juice.  It is therefore necessary to mix the skins back into the juice by one of many processes (punch down, pump over, rack and return, etc.)

Thermo-vinification uses heat to extract color and flavors from the skins.  The crushed grapes are heated to 60-75°C (140-167°F) for 20 to 30 minutes.  The must is then cooled down to fermentation temperature.  This process gives intensely colored must because the heat weakens the cell walls of the grape skins enabling the anthocyanins to be easily extracted.  This process can result in the wine having a rather “cooked” flavor.

Brenda flash 1While I was researching these technologies, I recalled a previous visit to Château de Beaucastel where I learned that make their iconic wine using a modified process of Thermo-vinification.  At Château de Beaucastel, the grapes are de-stemmed and the uncrushed grapes are passed rapidly through a heat exchanger at 90°C (194°F) which only heats the surface of the grapes, not the juice.  The heat is sufficient to weaken the cell wall of the grape skins enabling for easier extraction of anthocyanins, since the juice is kept cool the wine is less likely to have any cooked flavors due to this modified process.

Flash Détente is essentially an evolution of the traditional thermo-vinification method.  The process involves a combination of heating the grapes to about 82°C (180°F) and then sending them into a huge vacuum chamber where they are cooled.  During this cooling process the cells of the grape skins burst from the inside making a distinct popping noise.   Similar to traditional thermo-vinification, this process enables better extraction of anthocyanins and flavor compounds.

The Flash Détente process creates a steam that is diverted to a condenser.  This steam is loaded with aromatic compounds including pyrazines (vegetal, green pepper and asparagus).  Because vapor is removed, the sugar level increases in the remaining must.  The winemaker can choose to work with the higher sugar levels or dilute back down by adding water.  Most winemakers discard the condensation or “Flash Water” as the aromatics are usually highly disagreeable.   The winemaker now has multiple choices.  The flashed grapes can be pressed and fermented similar to white wine, the must can be fermented with the skins in the more traditional red wine production manner, or the flashed grapes can be added to non-flashed must that underwent classic maceration and then co-fermented.

Flash technology differs from traditional thermo-vinification because the traditional method does not involve a vacuum and there is no flash water waste produced.  Winemakers who are familiar with both methods have noted that the tannin extraction with thermo-vinification is less than Flash Détente.  Winemakers also note that Flash technology is better for removing pyrazine aromas.

Brenda flash 3In Europe during the early years of flash technology, it was mainly used for lower quality grapes or difficult vintages that had problems needing fixed.  Now the use of this technology is expanding its application to all quality levels of the wine industry.

According to Linda Bisson, a professor of viticulture and enology at UC Davis and one of the researchers working on the project, enologists are looking at what characteristics are lost or retained per grape variety.  They are also looking at the character and structure of tannins in flashed wines.  Bisson states that turning flashed grapes into a standalone wine is possible, but most winemakers see it as a tool for creating blends.  “It’s something on your spice rack to blend back in.”

The use of Flash Détente can be surmised as “It’s an addition to traditional winemaking, not a replacement.”

What are your thoughts on technology in the wine industry?  Does technology improve the wine or make it more homogenous?
