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.

  • 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.

Welcome to the world, Lamorinda AVA!

Hillsides of Contra Costa County at sunset

Hillsides of Contra Costa County at sunset

On Wednesday, February 24, 2016, the TTB approved the establishment of the Lamorinda AVA. The Lamorinda AVA is located in Contra Costa County, California, and includes part of the cities of Lafayette, Moraga, and Orinda. (California residents might recognize this area as part of the “East Bay.”) The new AVA is entirely contained within the San Francisco Bay Area AVA, which is itself entirely contained within the Central Coast AVA.

The new AVA covers a total area of nearly 30,000 acres,  much of it encompassed by suburbia,  but it is also home to 46 commercial vineyards with a total of 139 acres of vines. According to the original petition (filed on behalf of the Lamorinda Wine Growers Association in 2013), each individual vineyard is small – perhaps 5 acres or less – due to both the citified infrastructure and the hilly terrain.  In addition to the established vineyards, there are three larger commercial vineyards at various stages of being planned or established in the area; these might soon add another 130 acres of commercial vineyards to the region. There are currently six wineries operating in the area.

According to the petition, the unique features of the Lamorinda AVA include its soil, topography, and climate:

  • Topography: The terrain consists mainly of moderate-to-steep hills with narrow valleys. In contrast, areas further inland are much more rugged, and areas to the west are both flatter and at lower overall elevations.
  • Soils: The soils of Lamorinda tend to be thin, with high levels of clay and sand. In contrast, soils in the surrounding areas tend have more sedimentary and volcanic elements.
  • Climate: The Lamorinda area is, overall, warmer than the areas to the north, south, and west due to the presence of hills that block the cooling influence of the Pacific Ocean.  It is, however, cooler than the region located further inland, to its east.

Note: The name Lamorinda is a portmanteau from the names of the three cities that make up the region: Lafayette, Moraga, and Orinda.

Welcome to the world, Lamorinda AVA!

Saké…A Practical Guide

Today we have a guest post from Mark Rashap, CWE who, fresh from a holiday trip to Japan, gives us a practical guide to sake. Enjoy!

...

I hope you were able to read, enjoy, and garner some sight from my previous saké post, Tasting Saké from a … Champagne Perspective.  Focusing more on the sensory perception and the metaphorical side of saké, I left the practical and general explanation of saké for this post.  I hope to distill the pertinent information about the uniqueness of production, variety of styles, and different classifications that are important for any beverage professional in the US to know and understand.  For a more comprehensive yet still manageable guide, I would recommend John Gaunter’s The Saké Handbook.

Let us first tackle the differences in production from that of wine and beer.  First and foremost, all fruit, during their ripening cycle, naturally produce fermentable sugars (glucose and fructose).  This is obvious because when you taste fruit before fermentation, it will be sweet on the palate.  Grains are made up of starches, or long chain carbohydrates, that must be broken down through a process called saccharification.  In beer production, this is done in the mash by mixing water and grain, mostly barley, at various relatively high temperatures.  Enzymes in the grains are activated to break down the starches, then the sweet liquid is cooled so alcoholic fermentation can occur.  In saké production, rice grain cannot go through saccharification on its own, so a mold called Kōji-Kin (the Kōji is steamed rice plus the Kōji-Kin) is added and, under very controlled circumstances, winds up permeating the entire batch (or Moromi).  Because this saccharification happens at temperatures equivalent to those for alcoholic fermentation, both processes can and must happen simultaneously in the same vessel.

You might read very detailed accounts of how the Kōji is made, such as being cultivated in small slotted boxes and moved around every hour. All this is done so the mold is properly developed and consistently permeates the entire Kōji.  Additionally, a yeast starter, or Moto, occurs separately to ensure a healthy yeast population.  However, don’t let all this Japanese pomp and circumstance confuse you; all these processes are done simply to create a batch that has fully functioning saccharification and fermentation at the same time.  Every brewery does things slightly different, but this is the take home point.

...

Let’s review: rice is polished (more on this later).  It is washed, soaked, and steamed.  Part of it goes to the Kōji and part of it goes to the yeast starter.  These two separate batches are incrementally combined along with more water to ensure consistent mixing.  Saccharification and fermentation occur simultaneously for anywhere between 18-32 days.  It is pressed, usually filtered, usually watered back from 20 to 16 percent ABV, usually pasteurized twice, and bottled.  Violá!  When any of those “usuallys” don’t occur, there is a different name described below.

Now that you have the general idea of production, let’s talk about some variations and classifications.  All saké is classified as either Junmai, which means strictly made from water, yeast, kōji, and rice, or as Honjōzō, which has a small amount of brewer’s alcohol added just before pressing.  In my tastings, Junmai saké tends to have more delicate, pure, and subtle flavors, and Honjōzō sakés tend to be a bit fuller and rougher around the edges which might be desired in some situations.

The next uber-important variation of production is the amount of polishing before the brewing takes place.  With the varieties of rice commonly used for premium saké production, there are proteins, fats, and minerals occupying the outer layers of the rice grain that tend to cause off flavors in the finished saké.  Therefore, the outer layers are polished away to reveal the pure starches in the center of the grain.  It is easy to get confused by the percentage that is removed vs. the percentage left behind, so it is a good idea to get in the habit of referring to the polish as a percentage of what is left behind because that’s how the Japanese categorize it (called the Seimaibuai).  So, table rice will have a polish leaving 90% rice behind, cheap saké will be 80%, and most general saké is 70%.  Now for the important terms:  Ginjo is 60-50% left behind, and Daiginjo is between 50-35%.  So, the yields can be very low, and for the very best sakés only 35% of the grain remains after polishing!

...

So, to reinforce our understanding of this, within the Junmai (no distilled alcohol added) category: 70-60% grain remaining is simply called Junmai, 60-50% is Junmai Ginjo, and 50-35% is Junmai Daiginjo.  Within the category of Honjōzō (which is brewed with added distilled alcohol), simple Honjōzō is 70-60%, Ginjo (notice you don’t say Honjōzōginjo, it’s just Ginjo) is 60-50% polish, and Daiginjo is 50-35%.  I supposed you need to taste the difference between all these different categories for yourself for it to really sink in; do it comparatively just like when you’re trying to grasp the difference between Burgundy and Cali Pinot Noir.

Now there are a myriad of other styles, most of which are quite obscure, but there are a number worth detailing:

  • Nigori (cloudy):  this is saké that is unfiltered or filtered using a rough mesh.  The rice sediment left behind does give a sweeter profile.
  • Taru Saké: Sake which is aged in cedar barrels and has a woodsy aroma
  • Namazaké: unpasteurized saké.  This must be kept cold or else a haze and undesirable aromas will form.  It is thought of as fresher and livelier.
  • Tokubetsu (special):  bottles do not have to indicate what is special, but is usually a higher grade seimaibuai (polish) or special variety of rice.
  • Genshu: saké to which no water was added to bring down the alcohol to 16%.  These usually have 20% alcohol and have more robust flavors.  Popular as Genshu on the rocks.

It is easy to get wrapped up in all the minor details making understanding saké seem like an unattainable goal.  However, I believe that the information in this post will be a great foundation around which you can start to recognize the most important production terms on the label and make an educated guess as to what will be in the glass.  Of course, just like wine, we need to not be afraid of a different language, taste a wide variety of saké styles, take notes, and retain that information.  I hope that will be fun and rewarding!

What about Washington?

...

Today we have a guest post by an anonymous writer, who we know by the name Candi, CSW. Candi has developed respect for and enjoys the wines of  Washington State, and after reading her piece, we know you’ll have an appreciation for the wines of Washington State as well!

What about Washington?

When it comes to United States domestic production, many of us know that California continues to make the majority of our wine. And it’s easy to get caught up in the multitude of imports into the United States as well. But what about another key wine-producing state, number 2 or 3, depending on the source? I’m talking, of course, about Washington.

A Few Facts and Figures

Here’s an overview of the Washington’s wine “state of the state”. Please note that some of the information is based upon the 2014 Grape Crush Report.

  • Most of the industry has developed over the past 40 years, so it is relatively young compared to some areas.
  • Growth since around 1987 has been substantial. At that time, there were about 100 wineries. Now there are more than 850.
  • Wineries are predominantly small, family producers; these comprise about 800 of the 850 wineries.
  • Five varieties account for more than 75% of all wines produced. These include, in order of production, Riesling, Chardonnay, Cabernet Sauvignon, Merlot, and Syrah. More than 40 varieties are produced, however.
  • White wine production (53%) slightly exceeds red wine production (47%).
  • ...

    There are 13 appellations. The Yakima Valley appellation, established in 1983, is the oldest. The newest AVA, Ancient Lakes of Columbia Valley, was recognized in 2012. By comparison, the Napa Valley AVA was established in 1981.

  • Grapevines are typically grown on their own rootstock. The state generally experiences a winter freeze that reduces the risk of some pests, including phylloxera.
  • The predominant soil, loess, is so fine-grained that many vineyards require cover crops to keep the soil in place.

Dominant Varieties: Key Impressions

I recently had the opportunity to taste the wines of more than 15 producers. More than 40 wines were tasted, representing the 2011 through 2014 vintages. My overall impressions, based upon the tasting, are listed below. This may give you are a few ideas on ways to  get an exposure to what Washington has to offer.

  • Consider Riesling. These presented as fresh, floral, fruity, sometimes with a hint of minerals. Further, Rieslings seemed consistently good.
  • Chardonnay was also impressive, and with citrus aromas and flavors predominant. The typical acidity would bode well for pairing with a variety of foods.
  • Merlot clearly expressed Washington and AVA terroir. These wines were generally bolder, and more full-bodied, than many California examples. Think wines reminiscent of Chilean Merlot and even Carmenère. Note: that comparison IS a compliment!
  • Cabernet Sauvignon has the broad range of appeal similar to the state’s Chardonnay. Unlike some new world Cabernets, this wine can be more subtle and softer than the Washington Merlot.
  • Syrah appeared to be more terroir-specific than some Cabernets. Frequently spicy, a bit smoky, and full-bodied.

Wines, especially Chardonnay, Merlot and Cabernet, seem to be available in a wide range of prices. A bonus: wines often over deliver considering their price, so they appeal to those, like me, who seek value. And these varieties would make great party wines, too!

...

For those seeking “splurge” or special occasion red wines, look to Red Mountain AVA for Cabernet Sauvignon, Syrah and red blends. A splurge for white wine lovers: Bordeaux Blends of Sauvignon Blanc and Semillon.

May I Recommend?

The next time seafood is on the menu, think of a Washington Riesling if the dish is light. Something a bit heavier, maybe fatty fish? Consider a Washington Chardonnay.

When you want to pair a wine with strong cheese, lamb chops, or beef, look into a Washington Merlot, Cabernet, or red blend.

Cheers, and enjoy!
