Pinot Noir vineyards along the Kawarau River

On February 1 (2022), the New Zealand Office of Intellectual Property registered Bannockburn as an official geographical indication (GI) for wine production. Bannockburn is now a registered sub-region of the Central Otago GI (as well as a GI in its own right).

In New Zealand—as is done in most of the world of wine beyond Europe—geographical indications do not assign restrictions as to grape varieties or wine styles grown and produced, but rather define just the physical boundaries of a region.

Here are some of the defining characteristics of the newly minted Bannockburn GI:

  • The Bannockburn GI is located within the larger Cromwell Basin and defined by the Kawarau River and Lake Dunstan to the north and the high mountains of the Southern Alps—specifically the Cairnmuir and Carrick Ranges—to the east, south and west.
  • The southern edge of the area is drawn along a contour measured at 400 meters/1,320 feet above sea level. From this line, the area slopes gently down to an elevation of 195 meters/650 feet, with generally north-facing slopes and terraces.
  • Soil types include decomposed greywacke, schist, ancient lakebed sediment (alluvium), quartz (gravel), sand, and loess.
  • The location—within the Cromwell Basin and surrounded by mountains—means that rainfall is low and the climate is classified as “truly continental.”’
  • Bannockburn GI is the warmest part of Central Otago and further from the sea than most other points in New Zealand.

The leading grape varieties of the Bannockburn GI include Pinot Noir, Chardonnay, Pinot Gris, and Riesling. Minor plantings include Sauvignon Blanc, Chenin Blanc, Gewürztraminer, Pinot Blanc, and Grūner Veltliner. As of 2019, the area had total of 145 acres/350 hectares planted to commercial vines.

The first vinifera vines in the area were planted by John Olssen and Heather MacPherson in 1991. The term “Bannockburn” was first used on a wine label to indicate place-of-orign for grapes in 2009. At last count, there were six wineries operating in the area (and several others making wine from Bannockburn fruit). Current producers include Terra Sancta Winery, Felton Road Winery, Mount Difficulty, Carrick Winery, and Akura Winery.

Welcome to the world, Bannockburn GI!

Note: the Central Otago GI is considered to contain five other sub-regions. However, we have not (yet) found any evidence of an effort to declare these areas as geographical indications and as such, these other five sub-regions remain unofficial. For the record, they are: Gibbston; Cromwell, Lowburn and Pisa; Bendigo; Wanaka; and Alexandra.

Introducing…Sekt Austria PDO!

  By admin | February 3, 2022 - 9:09 am | ,
Leave a comment

Celebrating New Year with champagne and fireworksWith the debut of the Sekt Austria PDO, the Austrian Wine Marketing Board has announced a change in the way that the country’s sparkling wines will be classified and labeled. Prior to the change, these wines were labeled using the term Sekt gU—an initialism referring to the term geschützte Ursprungsbezeichnung. This change (announced on February 2, 2022 and effective immediately) is designed to draw attention to the fact that these wines—easily recognizable by the red-and-white striped banderole on the capsule—are produced using 100% Austrian grapes.

Three tiers of quality wine—including Reserve and Grosse Reserve—will be produced under the Sekt Austria PDO. Wine labeled under the Sekt Austria PDO designation may be made using any approved sparkling wine production method (including the tank method/méthode Charmat or transfer method); Reserve and Grosse Reserve wines must undergo a second fermentation and less aging in the bottle (according to the traditional method/méthode traditionelle of sparkling wine production).

Further details of these tiers are as follows:

  • Sekt Austria PDO:
    • Grapes must be harvested from a single (federal) state
    • Any approved sparkling wine production method may be used
    • Minimum 9 months aging on the lees
  • Sekt Austria Reserve PDO:
    • Grapes must be harvested from a single (federal) state
    • Grapes must be hand harvested
    • Must be produced using the traditional method
    • Minimum 18 months aging on the lees
  • Sekt Austria Grosse Reserve PDO:
    • Grapes must be harvested from a single municipality
    • Grapes must be hand harvested
    • Must be produced using the traditional method
    • Minimum 36 months aging on the lees
    • Wines may be labeled with a single vineyard as the designation of origin

Austrian Sekt PDO may be produced using any of the 40 grapes allowed for use in the production of Qualitätswein in Austria and must contain at least 3.5 atm of pressure. Click here for a list of The-Austria-40-wine-grapes-approved-for-use-in-Austria.

Note: Austria will continue to allow the production of Sekt without a geographical indication; such wines may be labeled with the term Austrian Sekt or Austrian Qualitätsschaumwein—without the notation of PDO.

As with all such updates, this change will need to wind its way through EU authorization; however, as the Austrian government has granted their approval, the changes will be in force (as scheduled) with the release of the wines of the 2021 vintage. If the EU fails to approve the amendment, the regulation will be rescinded (although this is quite unlikely to happen).

On November 4, 2021—after a long and winding road through the regulatory channels (the proposal was first drawn up in 2015)—the EU has registered Vino de Pago Urueña as a new protected designation of origin (PDO) for Spanish wine.

The new appellation, along with its single producer—Bodega Heredad de Urueña—is located in the Autonomous Community of Castilla y León in northwest Spain. The area—within the province of Valladolid—is famous for its medieval stone walls, restored city gates, and concentration of antiquarian bookstores (it has even been designated as a villa del libro (“city of books”).

The equally famous vineyards of Bodges Heredad de Urueña are located just to the north of the walled city. While the estate will continue to produce a range of grape varieties and styles of wine under the Vino de la Tierra Castilla y León designation, the wines produced under the PDO/Vino de Pago Urueña must be produced under the following guidelines:

  • Vino tinto/red wine:
    • Allowed grape varieties: Cabernet Sauvignon, Merlot, Syrah, Tempranillo
    • Minimum alcohol: 13% abv
    • Description, per the pliego: The red wines are very intense in color. They are cherry or garnet red, with purple tones appearing at the rim. They have a great amount of aromatic complexity due to the combination of grape varieties used and are particularly characterized by their roundness and an absence of sharp edges.
  • Vino rosado/rosé:
    • Allowed grape varieties: Cabernet Sauvignon, Merlot, Syrah, Tempranillo
    • Minimum alcohol: 12.5% abv
    • Description, per the pliego: Urueña rosés have raspberry-pink tones and the bluish notes of the Syrah variety, which occupies the largest proportion of the area under vines. Fresh fruit aromas predominate on the nose, together with some floral and caramel notes. The presence of red fruits is more characteristic of the Tempranillo rosés.

The Ancestor Vines of Barossa

Old vines…for many of us, the term “old vine” implies that a wine is produced from grapes grown on a grapevine of more than 20, or 50, or 100 years of age (the exact number depending on where exactly the vineyard is and your point of view). In addition, we believe that their fruit, having been painstakingly ripened by a grizzled old vine, will be exceptionally rich, concentrated, and complex.

While I am sure most wine aficionados would agree with that purposefully vague description, the truth remains that “old vine” (or vieilles vignes, as the French say) remains a largely unregulated and undefined wine term. After all, a lot depends on context. If you grow grapes in Châteauneuf-du-Pape or Jerez, the idea of “old” might actually start at about the half-century mark. On the other hand, if you grow grapes in the Canterbury Plains or Elkton, Oregon, you might start to think of your vines as “old timers” once the hit 20 years old.

One thing that just about everyone can agree upon, however, is that the older vines of the world need to be protected, respected, and – in the best of all possible worlds – documented and substantiated. To this end, Barossa Australia—formerly the Barossa Grape and Wine Association—which has over 500 grape growers and claims to have more old vines than any other region in the world, has taken steps to do so. After all, as Ron “The Dirtman” Gibson, of Gibson Wines in the Barossa says, “Old vines aren’t good because they’re old, they’re old because they are good.”

The organization has released what might be the only specific definition of the term “old vine” in the wine-making world. Although these terms are not regulated by the Australian Government—nor are they approved as official wine descriptors—this is at least a good first step in understanding and honoring the area’s old vines.

The classifications of Barossa’s old vines are as follows:

  • Old Vines: 35 years old or over
  • Survivor Vines: 70 years old or over
  • Centenarian Vines: 100 years old or over
  • Ancestor Vines: 125 years old or over

Barossa Australia has also published the “Barossa Old Vine Charter,” a declaration of sorts intended to protect and recognize the region’s oldest vines, some of which date back to 1909 or earlier and are to be considered part of Australia’s living history. The organization also keeps a Barossa Vineyards Register, which details the vineyards of the area by grape variety and by age.  The Barossa Vineyards Register, and the Barossa Old Vine Charter can be found on the website of Barossa Australia.

Dispatch from the León DO

  By admin | October 19, 2021 - 8:57 am | ,
Leave a comment

Map of Iberian Peninsula - Castile and LeonAttention, wine students! The Tierra de León DO (approved in 2007) has changed its name; the new name is: León DO.

The León DO is located along the Esla River, just a few miles (km) south of the city of León. It is perched atop the high plateau—the Meseta Central—that covers much of central Spain and as such, its vineyards are located at an average of 2,650 feet (800 m) above sea level.

The León DO is largely red wine country; more than 90% of its vines are planted to red grapes. The leading grape variety—accounting for nearly 70% of the region’s 4,100 acres (1,660 ha) of vines—is Prieto Picudo, typically the majority variety in the areas rich-and-fruity red wines (as well as a small showing of rosé).

Prieto Picudo is thought to be native to the area just south of the city of León and is found almost exclusively in Castilla y León. The vine tends to produce small bunches of compact grapes with somewhat thin skins. The wines produced using Prieto Picudo are known for their cherry-red hue, high aromatics (including cherry, red berry, black pepper, and forest floor) as well as a good zing of acidity and alcohol.

wine Map castilla y leonThe remainder of the of the (red grape) vineyards are planted to Tempranillo (occupying 17% of the area), Mencía (4%) and Garnacha Tinta (less than 1%). The tinta (red wines) of León are required to be made using a minimum of 60% (combined) Preito Picudo and/or Menía—a nod to these unique grapes considered to be native to the area. The remainder of the blend (up to a maximum [combined] of 40%) may be comprised of the accessory varieties—Tempranillo and Garnacha Tinta.

The León DO also produces a small amount of white wine; just under 10% of the area’s vineyards are planted to white grapes. Wine students will be interested to know that the regulations concerning the area’s white wines were recently updated, and that the current laws allow for just three white grapes— Verdejo, Albarín Blanco and Godello—to be so used. (Palomino and Malvasia are no longer allowed, as of the 2020 vintage).

The Rise of Ramato: Dispatch from the delle Venezie DOC

Dispatch from the delle Venezie DOC! The Disciplinare di Produzione for the delle Venezie DOC has been updated to allow for the production of rosato (rosé) and ramato styles of wine based on the Pinot Grigio grape.

As you may have guessed, there is a bit more to the story!

Winemakers in the northeast of Italy (namely Friuli-Venezia Giulia. Veneto, and the Trentino-Alto Adige) have successfully grown Pinot Grigio—brought to the region via France where it is known as Pinot Gris—for hundreds of years.

The area’s Pinot Grigio is typically produced as a dry, crisp, easy-to-love and fruity white wine with a light yellow(ish) color. This style of wine is enormously popular; so much so that a multi-regional DOC area—the delle Venezie DOC—was created in 2017 to grant these delightful wines a bit of the respect they deserve and allow varietally-labeled Pinot Grigio from Veneto Region, Friuli-Venezia Giulia Region, and the Trentino Province to wear the DOC label. (Sparkling Pinot Grigio and white wine blends—bianco—based around Pinot Grigio, Chardonnay, Pinot Bianco, Muller Thurgau, Garganega, Verduzzo, and/or Tocai Friulano are also approved for production under the delle Venezie DOC.)

.

.

Despite the popularity of the fresh-and-fruity style of Pinot Grigio, winemakers in Italy’s northeast have traditionally spun Pinot Grigio into other styles of wine as well. A light pink rosato/rosé is created by allowing the juice (post-crush) to macerate alongside the skins of the grey/pink hued grapes for a short period of time (such as 6 to 10 hour, or perhaps us to 24 hours).  If the maceration on the skins is allowed to continue for a longer period of time—such as two weeks or more—the result can be a richly textured, copper-hued wine known a ramato—from the Italian word rame meaning copper. 

The ramato style of wine production is believed to have originated in Friuli-Venezia Giulia. Pinot Grigio Ramato was quite popular up until the 1960s, when exports of the more widely recognized style of Pinot Grigio from Santa Margherita and other wineries exploded in popularity. However, some producers continued production of rosato and ramato styles of Pinot Grigio, and like so many traditional products in the world of food and wine…these traditional products are increasingly appreciated once again. The delle Venezie Consorzio—in partnership with the Centro di Ricerca Viticoltura ed Enologia (Research Center for Viticulture and Enology) in Conegliano—has supported these efforts via research into 17 different clones of Pinot Grigio in an effort to identify those most appropriate for use in rosato and ramato.

The recent update in the delle Venezie DOC regulations acknowledges the historic significance—and current appreciation of the Pinot Grigio Rosato and Pinot Grigio Ramato produced in Italy’s northeast. Time to raise a glass!

Note: the delle Venezie DOC is also known as Beneških Okolišev (in Slovenian).

Welcome to the World, Ulupalakua AVA!

  By admin | July 5, 2021 - 11:11 am | ,

WaianapanapaHere’s a first: Hawaii gets its very own American Viticultural Area (AVA)!

Despite being located in the tropics (the AVA itself sits at about 20°N latitude) and not being particularly well-known for grape-based viticulture or wine production, here it is: an AVA located in a small corner of the island of Maui—where grapes are grown and sent to a winery just a few miles away to be made into wine.

The Ulupalakua AVA is the first AVA to be approved in the state of Hawaii. When the new AVA comes into force on August 2, 2021, there will be a total of 257 AVAs in the United States.

Map via the TTB AVA Explorer

Map via the TTB AVA Explorer

According to the original petition for the AVA—submitted by Mark Beaman, the former winemaker at Maui Wines—the distinguishing features of area include its topography, soils, and climate, as discussed below:

Topography: The area within the Ulupalakua AVA contains a series of four distinct, southwest-facing areas of gently sloping benchlands. In contrast, the area surrounding the new AVA consists of steeper slopes, ravines, and exposed volcanic rock. The elevation of the vineyards in the AVA ranges from 1,560 feet/475 m (in the western portions) to 1,850 feet/564 m (in the east). 

Soils: The Ulupalakua AVA is located on the western slopes of Mount Haleakala—a massive shield volcano that covers more than 75% of the island of Maui. The soils of the area are predominantly composed of volcanic ash and the weathered remains of igneous volcanic rock. About 20% of the soil contains silt, loam, and clay. It is believed that they combination of soils creates an area that is fertile enough to support healthy vines, but not so fertile as to promote excessive foliage.

Map via the TTB AVA Explorer

Map via the TTB AVA Explorer

Climate: The climate within the Ulupalakua AVA reflects its tropical location and rarely drops below 50°F/10°C or goes above 85°F/29°C. The region receives quite a bit of rain—an average of 30.7 inches of rainfall a year. However, it is noted that less than two inches per month tend to fall in July and August. While humidity can certainly be seen as an issue, this period of low summer rainfall reduces the risk of mildew and rot in the days leading up to the harvest, and the mild summertime temperatures protect again sunburn and heat stress.

It is believed that viticulture began in the area in the early 1800s when an immigrant from Portugal—Don Francisco de Paula Marin—imported vines into the region and made small amounts of wine. These days, the total area within the Ulupalakua AVA comprises 70 acres; of these, 16 acres are currently under vine. Leading grape varieties include Gewurztraminer, Chenin Blanc, Viognier, Grenache, Malbec, and Syrah. There is currently one commercial vineyard— Ulupalakua Vineyards owned by Maui Wine LLC—in the region. There are no bonded wineries within the AVA, but grapes are often sent to Maui Winery (located about just a few miles away) for processing.

The name “Ulupalakua” is derived from the native language of Hawaii and may be loosely translated as “breadfruit ripened on the back.” The folklore of the area tells of how the island’s king would request that his favorite fruit—breadfruit—be brought to his home on the west coast of Maui. Harvesters would pick the unripe fruit on the island’s eastern side and carry it to the king’s house on the other side of the island. The fruit would ripen on the journey and would be totally ripe by the time they reached (the area now known as) Ulupalakua.

Welcome to the World, Goose Gap AVA!

Map via the TTB AVA Explorer

On July 1, 2021, the TTB (Alcohol and Tobacco Tax and Trade Bureau) of the United States announced a newly-approved American Viticultural Area (AVA) for Washington State: Goose Gap AVA. When this new AVA comes into force—on August 2, 2021—the total number of AVAs in the United States will be 256; of these, 19 will be located in Washington State.

Goose Gap is the third new AVA to be approved in Washington State this year; two others—The Burn of Columbia Valley and White Bluffs—were announced just last month (June 17, 2021).

The Goose Gap AVA—a sub-region of both the Yakima Valley AVA and the larger Columbia Valley AVA—is located in Washington State’s Benton County. The triangle-shaped area is tucked between (and to the south of) the Red Mountain AVA and the tiny Candy Mountain AVA.

According to the petition—submitted by Alan Busacca, PhD, on behalf of the Goose Gap Winegrowers Association—the distinguishing features of the Goose Gap AVA include its topography and soils, as discussed below:

Topography: The Goose Gap AVA surrounds (and is mainly to the north of) a basalt ridge known as Goose Hill (sometimes referred to as Goose Mountain). The topography of the area is such that most of the south- and southwest-facing slopes in the area are too steep for successful viticulture; therefore, many of the new AVA’s vineyards are planted on north- and northeast-facing slopes. As a result, the vines in the Goose Gap AVA receive less solar radiation than those planted on the south- and southwest-facing slopes of the nearby appellations, leading to longer growing periods and later harvest dates for the vines of the Goose Gap.

The elevation within the Goose Gap AVA ranges from 577 feet (176 m) above sea level (at the southern boundary) to 1,339 feet (408 m) atop of Goose Hill.

Map via the TTB AVA Explorer

Map via the TTB AVA Explorer

Soils: Many of the soils in the area—covering about 65% of the appellation—consist of wind-blown loess over layered silt and fine-textured sand. In many spots, this topsoil extends for six feet with no hardpan or other root impediments. Other areas of the appellation are also covered by loess, but with varying depths of loess as well as vary amounts of fractured basalt and flood sediment atop the underlying basalt bedrock. The soils of the Goose Gap AVA contain a higher overall percentage of loess, silt, and sand than the soils of the surrounding areas.

The area within the Goose Gap AVA covers a total of 8,129 acres; of these, 1,800 acres (728 ha) are planted to vines. The region is currently home to two commercial vineyards—including the 1,700-acre (688 ha) Goose Ridge Estate Vineyard—and one bonded winery (Goose Ridge Winery). Commercial vineyards specializing in Cabernet Sauvignon and Merlot have been planted in the area since 1998. Other forms of agriculture—including apple orchards, cherry orchards, alfalfa fields, and sheep grazing are traditional to the area.

About that name: The new AVA is located along the migratory path of several flocks of wild geese. The local use of the term “Goose Gap” as well as “Goose Hill” can be traced back to the early 1900s. The area bears the tales of many legendary goose hunts from the 1800s; First Peoples are known to have hunted geese in the area as well.

Map via the TTB AVA Explorer Map

On June 17, 2021, the TTB (Alcohol and Tobacco Tax and Trade Bureau) of the United States approved the Palos Verdes Peninsula AVA. When this new AVA comes into force—on July 19, 2021—the total number of AVAs in the United States will be 255, of which 142 will be in California.

The Palos Verdes Peninsula area—located in the southwestern corner of Los Angeles County—hugs the Pacific Ocean coastline about 25 miles west of downtown Los Angeles. The region includes the cities of Palos Verdes Estates, Rolling Hills Estates, Rancho Palos Verdes, and Rolling Hills, California. The area is highly regarded for its sweeping views of the ocean and the Los Angeles city skyline, gated communities, and high-dollar homes. However, the area has a long history of agriculture—including some viticulture—and wine continues to be produced in the area.

According to the original petition—spearheaded by James York of Catalina View Wines and submitted on behalf of a group of Palos Verdes Peninsula winegrowers—the area’s distinguishing characteristics include its topography, soils, and climate. These are discussed below:

Topography: The area within the Palos Verdes Peninsula AVA consists of low rolling hills (technically part of the Coast Range) situated between the Los Angeles Basin and the Pacific Ocean. Elevations range from sea level (on the region’s western and southern edges) to 1,460 feet/445 m above sea level at San Pedro Hill. Many of the region’s vineyards are planted on moderate south- or southeast-facing slopes. 

Map via the TTB AVA Explorer Map

Map via the TTB AVA Explorer Map

Soils: The soils of the region include Altamont Clay Adobe, Altamont Clay Loam, and Diablo Clay Adobe. These soils are composed primarily of fine-grained sandstone, weathered shale, silt, and calcareous clay.  These soils retain allow for moisture retention in dry weather while allowing for drainage during rainy times.

Climate: Like many areas of Southern California, the Palos Verdes Peninsula AVA has an overall Mediterranean Climate coupled with the coastal influence of the nearby Pacific Ocean. The area typically experiences warm, dry summers (temperatures rarely exceed 84°F/29°C) and mild winters with limited rainfall.

The Palos Verdes Peninsula AVA includes a total of 15,900 acres; of these, just over 7 acres are currently planted to vines. Two producing wineries—Catalina View Wines and La Caze Family Vineyard—are located within the region. The leading grape varieties include Pinot Noir, Chardonnay, Cabernet Sauvignon, and Merlot

Welcome to the World: The Burn of Columbia Valley AVA!

Map via the TTB AVA Explorer Map

Map via the TTB AVA Explorer Map

On June 17, 2021, the TTB (Alcohol and Tobacco Tax and Trade Bureau) of the United States approved two new American Viticultural Areas (AVAs): the White Bluffs AVA and the Burn of Columbia Valley AVA. When these new AVAs come into force—on July 19, 2021—the total number of AVAs in Washington State will be 18.

This article will focus on the Burn of Columbia Valley AVA. Click here for an article focusing on the While Bluffs AVA.

The Burn of Columbia Valley AVA (a sub-region of the Columbia Valley AVA) is located in the southwest corner of the Columbia Valley AVA, along a stretch of benchland on the north bank of the Columbia River. It is situated between the Horse Heaven Hills AVA (to its east) and the Columbia Gorge AVA (to its west). Its location along the Columbia River places it adjacent to the border between Washington State and Oregon—although it lies 100% in Washington State.

The petition to establish The Burn of Columbia Valley AVA (originally slated as “The Burn”) was submitted by Kevin Corliss of Ste. Michelle Wine Estates, Joan Davenport (Professor of Soil Sciences at Washington State University), and John Derrick of Mercer Ranches. According to the petition, the area’s distinguishing features include its topography, climate, and soils—as discussed below.

Topography: The area within the new AVA is situated on a moderately-elevated, gently sloping benchland above the Columbia River. The (generally) southeast-facing slope averages just over 7% grade.

Map via the TTB AVA Explorer Map

Map via the TTB AVA Explorer Map

Climate: The area is considered (overall) one of the warmer regions of the Columbia Valley. However, due to the persistent winds from the Columbia Gorge, the heat (as measured by “degree days”) accumulates much more slowly than in the surrounding areas. As a result, the growing season is extended—the grapes in this area are often among the last to be harvested in the state. This lengthy growing season allows for deep flavor development and excellent acid retention in the grapes.

Soils: The soils within the new AVA—dominated by Walla Walla silt loam—are, in many aspects, similar to those of the surrounding areas. However, the soils within The Burn contain a higher proportion of organic matter and lower levels of sand/sandy loam—and, as a result, the soils of The Burn have higher water- and nutrient-retention capacity. This means that the region has a lower need for supplemental irrigation, a lower need for the use of supplemental vine nutrients, and a reduced risk of winter vine injury as compared to the surrounding areas.

The triangle-shaped Burn of Columbia Valley AVA covers a total of 16,870 acres. Of these, approximately 1,500 acres/607 ha have been planted to vines. The region contains two commercial vineyards and no bonded wineries (as of 2021). This is a young growing area; while vines have been planted in the area since 2002, the majority of the vines have been planted since 2015. Cabernet Sauvignon is the leading variety, followed by Syrah, Malbec, Chardonnay, and Sangiovese.

About that name: there is no easy consensus on where the name—The Burn—originated, although there is plenty of evidence that it has been used in reference to the area for generations. The Burn might refer to a local legend that tells of early settlers who set fire to the benchland every fall in order to rejuvenate the native grasses and provide for their horses in the springtime. It could also be based on the Gaelic- German- and English-inspired use of the term burn (as in Bannockburn)—or born (as in Padderborn) or bourne (as in Melbourne)—to refer to a stream or a river.

Welcome to the world: The Burn of Columbia Valley AVA!

P.S. The TTB has also announced a new AVA in California—Palos Verdes Peninsula—to be effective on July 19, 2021. Click here for more details.
