The Russian River Valley AVA is an American Viticultural Area (AVA) in Sonoma County, California. Centered on the Russian River, the Russian River Valley AVA accounts for about one-sixth of the total planted vineyard acreage in Sonoma County. The appellation was granted AVA status in 1983 and enlarged in 2005. [1] The area generally lies between Sebastopol and Santa Rosa in the south, and Forestville and Healdsburg in the north. [1] [4] The Russian River Valley has a characteristically cool climate, heavily affected by fog generated by the valley's proximity to the Pacific Ocean. The area is known for its success with cool climate varietals, notably Pinot noir and Chardonnay. [3]

Geography and climate

Despite its name, the Russian River Valley AVA does not cover the entire Russian River Valley-which extends north into Mendocino County, California and southwest all the way to the Pacific Ocean. Originally the river continued south and emptied into San Francisco Bay but during its history, for reasons not yet understood by geologists, the river changed course. [5] The small segment of the river valley that makes up the AVA begins near Healdsburg once the river leaves the Alexander Valley region through a narrow gorge in the foothills of the Mayacamas Mountains. From there it extends south to the Santa Rosa Plains and Sebastopol and west to the towns of Monte Rio, Guerneville and Occidental. Within the boundaries of the Russian River AVA are the sub-AVAs Chalk Hill and Sonoma Green Valley. [6] In 2003 the AVA was expanded to include 767 acres (310  ha ) south of Fulton. [7]

The geography of the Russian River Valley was shaped millions of years ago by collisions between the North American and Pacific tectonic plates and eruptions by volcanic vents that deposited volcanic ash over layers of eroded bedrock. This created sandstone of loam known as "Goldridge soil". [5] Some of the area's most respected Pinot noir and Chardonnay vineyards are planted along deposits of Goldridge soil. Near the town of Sebastopol, a different soil that is more clay based, known as "Sebastopol soil" has also shown itself to work well with Pinot noir due to its ability to retain less water than Goldridge soil. [8] This soil was created by water flowing off the Sonoma Mountains that carried with it clay deposits. A third soil type, found close to the river, is predominantly alluvial and makes up the benchland regions of the river. [5]

With parts of the AVA located less than 10 miles (16 kilometers) from the Pacific, the climate of the Russian River AVA is characterized by cool morning fog that comes in from the ocean through the Petaluma Gap and burns off during the day. [9] The cooling influence of the fog is responsible for the large diurnal temperature variation with nighttime temperatures dropping as much as 35 to 40 degrees Fahrenheit (about 20 °C) from daytime high. [5] The Russian River is a rain-fed waterway that swells in the wintertime and provides vital irrigation to the region's vineyards during the dry season in late spring. In the summertime, the warmth of the season is tempered by the maritime influence of fog that facilitates a long, slow ripening period and limits the risk of over ripeness or "baked" flavors in the grapes. Harvest in the Russian River Area often take place at later dates than in its neighboring regions. [5] The central and western reaches of the AVA are the coolest and tend to be most extensively planted with Pinot noir and Chardonnay. The eastern parts of the AVA, located near US 101 and include the sub-AVA of Chalk Hill, are the warmest areas of the Russian River AVA being the furthest away from the ocean. [8]

Boundary disputes

The Russian River AVA has had a number of disputes regarding the expansion and revision of the appellation boundaries. In 1997, the Russian River Winegrowers association attempted to expand the AVA all the way down to the town of Cotati in the southeast corner of Sonoma County. This proposal was rejected by the Bureau of Alcohol, Tobacco, Firearms and Explosives for being too broad in scope. In 1999, the grower's association filed a new proposal to revise the boundaries based on the influences of coastal fog. Under this proposal the warmer Chalk Hill sub-AVA, which has little fog influence, would be excluded from the Russian River AVA and more acreage along the southwest corner of the AVA would be added. [10] That proposal was later rejected as well. In 2003, a new proposal was issued expanding the AVA 767 acres (310 ha) on the south western end near the Green Valley region. [2] This expansion was approved later that year. [7]

In 2008, E & J Gallo petition for a further expansion of the AVA in the southwestern corner of 14,000 acres (5,700 ha) that would include the winery's Two Rock Vineyard located along the Highway 101 corridor near Cotati in the AVA. If approved, the petition would expand the AVA's total acreage to 169,000 acres (68,000 ha). When first proposed, the Russian River Winegrowers Association voted unanimously to oppose the expansion on the grounds that the proposed area is climatically different from the rest of the Russian River areas. Gallo contested that opinion and after changes in leadership the grower's associations officially takes a neutral stance on the proposal though some vocal opposition still exist. [11] As of a meeting of the members on December 9, 2008, the Russian River Winegrowers are opposed the proposed expansion. [12]

History

Viticulture in the Russian River region dates back to the 19th century when immigrants from Mediterranean countries descended upon the region and began planting vines. While most vineyards were "gardens" for personal family consumption, commercial wineries sprung up and by the dawn of the 20th century there were nearly 200 wineries operating. The advent of Prohibition in the United States dealt a devastating blow to the region with many wineries going out of business. Some winemaking families continued to make wine illegally and others converted to bootlegging a sugar and water base wine known as "Jackass brandy" to survive during this period. [8] (Today one of the most prestigious vineyards in the region is the Jackass Hill Vineyard owned by Martinelli Winery.) At the end of Prohibition the few vineyards that were operating would sell their grapes to bulk jug wine producers. It would not be until the 1970s that vineyards in the Russian River region would begin to focus on quality wine production and begin using their grapes for local bottlings. The 1973 vintage of Foppiano Vineyards claims to be the first wines to include the words Russian River on their wine labels. The winery giants of E & J Gallo and Kendall Jackson invested significantly in the region in the late 20th century with Gallo purchasing the large Laguna Ranch vineyard for its flagship "premium" Chardonnay under its Gallo of Sonoma label in 1970 and purchasing the Twin Valley Ranch once owned by actor Fred MacMurray for its MacMurray Ranch label. Gallo's rival Kendall Jackson pumped more than $12 million into updating and establishing its La Crema label in the Russian River region. [8]

The Freeman Vineyard & Winery was founded in 2001.

In 1983, the region was approved for AVA status. Over time the region began to develop a reputation for the quality of its Chardonnay and Pinot Noir for both still and sparkling wine production. In the late 1990s and early 21st century, as the popularity for Pinot Noir grew, the region saw an explosion of investment with Pinot plantings jumping from 4,000 acres (1,600 ha) to over 12,000 acres (4,900 ha) by 2003. [6]

Grape varieties

According to the trade group Russian River Valley Winegrowers, 42 percent of the grapes harvested in the region are chardonnay, while 29 percent are Pinot noir. While the region is predominantly associated with Chardonnay and Pinot noir, hillside vineyard locations have shown success with other varieties such as Syrah and Zinfandel. [6] Within the AVA there are several microclimates that allow for suitable plantings of Sauvignon blanc, Gewürztraminer, Petite Sirah, Cabernet Franc and Merlot. [8] In warmer areas of Chalk Hill there have been successful plantings of Cabernet Sauvignon. [9] Even for these non-Burgundian varietals, the nature of the Russian River Valley's cool climate can be seen in the wine. For example, Russian River Merlots tend to have distinctive tea-like note and Zinfandels tend to exhibit more tart red fruit than Zinfandels from the warmer Dry Creek AVA. While Sauvignon blanc from the region tend to be slightly less "grassy" they still tend to exhibit herbal and citrus lime aroma. [13] Despite its close proximity, the Russian River AVA produces Chardonnays that are dramatically different from those found in the Alexander Valley AVA. The region's cool climate produces more grapes with higher acidity that tend to be more balanced than the fatter, creamy style found in the Alexander Valley. Grapes from the Russian River and smaller Green Valley areas have been prized by sparkling wine producers for their crispness and high quality. [9]

Pinot noir

As of 2008, the Russian River Valley accounted for nearly 19% of all the Pinot noir plantings in California and 10% of all grape varieties planted in Sonoma County. Older clones planted in the mid to late 20th century, including the Martini, Swan, Pommard, and 115 clones, produced a "classic" style of Russian River Pinots that were characterized by vibrant (but pale) color, lively acidity, cherry and berry fruit flavors and delicate aroma that would often include earthy mushroom notes. While that style had it share of fans, the lack of coloring would be a factor in poor score wine ratings from wine critics. In response to these poor scores, some Russian River winemakers altered their techniques in order to enhance the color. These techniques ranged from blending in the darker color Alicante Bouschet and Syrah or the red wine concentrate known as "Mega Purple", to extended maceration and oak extraction that added more weight and extraction of phenolic compounds that add color to the wine. Other winemakers altered some of their viticultural practices in the vineyards, including adopting new trellising systems that allowed for more leaf removal which exposed the grapes to more sunlight. In addition to enhancing some of the color producing phenols, the new trellising also served to increase sugar content (and subsequently alcohol levels) and decrease the amount of the green tasting pyrazine compounds found in the grapes. The style of Pinot noir produced from these techniques tend to be heavier, more fuller bodied and almost "Syrah-like". [13]

Pinot noir Red wine grape variety

Pinot noir is a red wine grape variety of the species Vitis vinifera. The name may also refer to wines created predominantly from Pinot noir grapes. The name is derived from the French words for pine and black. The word pine alludes to the grape variety having tightly clustered, pine cone-shaped bunches of fruit.

Alexander Valley AVA

The Alexander Valley is a Californian American Viticultural Area (AVA) just north of Healdsburg in Sonoma County. It is home to many wineries and vineyards, as well as the city of Cloverdale. It is the largest and most fully planted wine region in Sonoma. Highway 101 runs through the valley, and the Russian River flows down the valley, surrounded by vineyards on both sides. From the higher elevations of the valley rim, there is a view as far south as Taylor Mountain and Sonoma Mountain. The region was named for Cyrus Alexander, owner of a part of the Rancho Sotoyome Mexican land grant, in 1847. Granted AVA status in 1984, the boundaries of the appellation are defined in the Code of Federal Regulations, Title 27, Section 9.53.

New Zealand wine Wine produced in New Zealand

New Zealand wine is produced in several of its distinct winegrowing regions. As an island country in the South Pacific Ocean, New Zealand has a largely maritime climate, although its elongated geography produces considerable regional variation from north to south. Like many other New World wines, New Zealand wine is usually produced and labelled as single varietal wines, or if blended, winemakers list the varietal components on the label. New Zealand is best known for its Marlborough Sauvignon Blanc, and more recently its dense, concentrated Pinot Noir from Marlborough, Martinborough and Central Otago.

The state of Oregon in the United States has established an international reputation for its production of wine, ranking fourth in the country behind California, Washington, and New York. Oregon has several different growing regions within the state's borders that are well-suited to the cultivation of grapes; additional regions straddle the border between Oregon and the states of Washington and Idaho. Wine making dates back to pioneer times in the 1840s, with commercial production beginning in the 1960s.

Rogue Valley AVA

The Rogue Valley AVA is an American Viticultural Area located in southern Oregon. The federal government approved this appellation in 1991. It is entirely contained within the larger Southern Oregon AVA and includes the drainage basin of the Rogue River and several tributaries, including the Illinois River, the Applegate River, and Bear Creek. Most wineries in the region are found in the valleys formed by one of these three tributaries, rather than along the Rogue River itself. The region is 70 miles (113 km) wide by 60 miles (97 km) long ; there are fewer than 20 wineries with only 1,100 acres (450 ha) planted. Each river valley has a unique terroir, and grows different varieties of grapes. Overall, however, this region is the warmest and driest of Oregon's wine-growing regions.

Columbia Gorge AVA American Viticultural Area

The Columbia Gorge AVA is an American Viticultural Area which includes land surrounding the Columbia River Gorge, straddling the border between Oregon and Washington. Due to the significant gradations of climate and geography found in the gorge, this AVA exhibits a wide range of terroir in a relatively small region; it is marketed as a "world of wine in 40 miles".

Mendocino County wine

The Mendocino County wine is an appellation that designates wine made from grapes grown mostly in Mendocino County, California. The region is part of the larger North Coast AVA and one of California's largest and most climatically diverse wine growing regions. Mendocino County is one of the northernmost commercial wine grape regions in the state with two distinct climate zones separated by the Mendocino Range. Ten American Viticultural Areas have been designated within Mendocino County. Mendocino is one of the leading wine growing regions for organically produced wine grapes. Nearly 25% of the acreage in Mendocino County is grown organically. In 2004, the residents of the county voted to become the first GMO-free county in the United States in an initiative that was supported by many of the county's largest wineries. The county's widespread focus on organic viticulture has inspired journalists to describe it as "California's organic wine Mecca".

Sonoma County wine

Sonoma County wine is wine made in Sonoma County, California, in the United States.

The Mendocino Ridge AVA is a coastal, cool climate and high altitude American Viticultural Area located entirely within the coastal zone of Mendocino County, California. The boundaries of the AVA encompass the coastal ridges adjacent to the Pacific Ocean that reach inland toward the Anderson Valley. Roughly 36 miles of the southernmost portion of the Mendocino Coast make up the western boundary of the AVA, with the Sonoma County line as the southern boundary, the Navarro River as the northern boundary and Anderson Valley as the inland boundary running northwest–southeast. The Mendocino Ridge AVA "is essentially a northern extension of the true Sonoma Coast viticultural area." However, the Mendocino Ridge AVA designation is unique in that it is limited by elevation, reserved only for vineyards at or above 1200 feet. This is why the Mendocino Ridge AVA has been nicknamed "Islands in the Sky®," because the vineyards sitting at 1200 feet or higher are often perched above thick fog moving inland from the Pacific Ocean blanketing the coast and the valleys between the ridge tops, making the tips of the mountains look like islands protruding from a sea of fog. In this overlapping, "[t]he Mendocino Ridge AVA floats above the Anderson Valley and Mendocino appellations." Mendocino Ridge is the only non-contiguous AVA in the United States; all others are contiguous landmasses with all vineyards inside the boundaries designated as part of the AVA, whereas Mendocino Ridge in comparison only includes the higher altitude growing sites. "There are 262,400 acres within the outer boundaries of the Mendocino Ridge viticultural area, but the actual viticultural area encompasses only 87,466 acres which lie above 1,200 feet elevation. Of these 87,466 acres, approximately 1,500 to 2,000 acres of the ridge tops are suitable for vineyards. The side-slopes are very steep and covered with timber, making them unfit for planting". Estimates of planted acres range from 233 to 410, which accounts for about 0.3% of the total area. These planted acres are scattered among 16 remote vineyards.

The Santa Cruz Mountains AVA is an American Viticultural Area centered on the Santa Cruz Mountains. Its territory expands in three California counties, Santa Clara, Santa Cruz and San Mateo. Established in 1981 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Santa Cruz Mountains AVA was among the first to be defined by its mountain topography. Based on elevation, it largely follows the fog line along the coast, extending down to 800 feet (240 m) on the eastern slope toward San Francisco Bay, 400 feet (120 m) on the western slope to the Pacific Ocean and extending toward the ridgecrests at 3000+ feet elevation.

Los Carneros AVA

Los Carneros AVA is an American Viticultural Area which includes parts of both Sonoma and Napa counties in California, U.S.A. It is located north of San Pablo Bay. The proximity to the cool fog and breezes from the bay makes the climate in Los Carneros cooler and more moderate than the wine regions farther north in Napa Valley and Sonoma Valley. The cooler climate has made Los Carneros attractive for the cultivation of cooler climate varietals like Pinot noir and Chardonnay. Many of the grapes grown in Los Carneros are used for sparkling wine production. Receiving its AVA status in 1983, the Carneros area was the first wine region in California to be defined by its climate characteristics rather than political boundaries.

The Northern Sonoma AVA is an American Viticultural Area in Sonoma County, California, United States. The appellation covers most of the county with the notable exceptions of the Los Carneros AVA and Sonoma Valley AVA wine regions, which are located in the southern portion of the county. The creation of this AVA was largely based on the petitioning of the E & J Gallo Winery as part of their expansion of their Gallo of Sonoma brand. The viticultural area incorporates the Alexander Valley AVA, Chalk Hill AVA, Dry Creek Valley AVA, Knights Valley AVA, Russian River Valley AVA, Sonoma Coast AVA, and parts of the Green Valley of Russian River Valley AVA and Rockpile AVA valleys.

Spring Mountain District AVA

The Spring Mountain District AVA is an American Viticultural Area located in the Napa Valley AVA in California. Spring Mountain District AVA was officially established as an American Viticulture Area in 1993. Encompassed within its bounds are about 8,600 acres (3,480 ha), of which about 1,000 acres (400 ha) are planted to vineyards. Given the small crop yields on hillsides, the region represents less than 2% of Napa Valley wine. Currently the region has just over 30 winegrowers.

California wine Wine made from grapes grown in California, United States

California wine production has a rich viticulture history since 1680 when Spanish Jesuit missionaries planted Vitis vinifera vines native to the Mediterranean region in their established missions to produce wine for religious services. In the 1770s, Spanish missionaries continued the practice under the direction of the Father Junípero Serra who planted California's first vineyard at Mission San Juan Capistrano.

Leona Valley AVA is an American Viticulture Area (AVA) in northeastern Los Angeles County, California. It is located in Leona Valley within the Sierra Pelona Mountains of Southern California.

El Dorado AVA

The El Dorado AVA is an American Viticultural Area located in El Dorado County, California, United States. Wine grape growers in the region produce a large diversity of varietals, notable varietals are Zinfandel, Barbera, and Syrah and there are significant plantings of Rhône varietals. Located in the foothills of the Sierra Nevada mountains, vineyards are found primarily at elevations between 600 feet (183 m) and 3,500 feet (1,067 m) above sea level and some of the best vineyards are planted above 2,000 feet (610 m) elevation. The region benefits from the cool breezes that come off the mountains and push hot air off the vines and down to the valley. The soils of the region are magma based with high levels of acidity.

Lake Chelan AVA

The Lake Chelan AVA is an American Viticultural Area (AVA) in Washington State. Located in the north-central part of the state around Lake Chelan, the area is a sub-appellation of the greater Columbia Valley AVA. Of the 24,040 acres within the AVA's boundaries, only 260 acres were planted with wine grapes which was producing wine for fifteen wineries as of 2009. While viticulture has existed in the region since 1891, the area was approved as a federally designated wine region in April 2009 when it became Washington's 11th AVA.

Benovia Winery

Benovia Winery is a family-owned producer of Pinot noir, Chardonnay, and Zinfandel wines in Santa Rosa, California. Founded in 2005 by Joe Anderson and Mary Dewane, Benovia Winery farms three estate vineyards which total 71.67 acres (290,000 m2) and are located in the Russian River Valley AVA and Sonoma Coast AVA in Sonoma County. To supplement the fruit it harvests each year, Benovia purchases additional grapes from two sites farmed by the Martinelli family. Benovia's winemaker, Mike Sullivan, is also co-owner of the winery. Benovia wines are produced and bottled at the winery's winemaking facilities at the Martaella Estate Vineyard in the Russian River Valley AVA. Annual production is approximately 6,000 cases. Benovia wines are sold direct to customers, as well as distributed to restaurants and other retailers for resale.

Petaluma Gap AVA is an American Viticultural Area established on January 8, 2018 by the U.S. Department of Treasury’s Alcohol and Tobacco Tax and Trade Bureau (TTB). The area spans 202,476 acres (316 sq mi) stretching through an 30 miles (48 km) inland valley from the Pacific coast at Bodega Bay southeast to Highway 37 at Sears Point on San Pablo Bay straddling the border of northern Marin and southern Sonoma counties. The AVA lies entirely within the North Coast AVA and partially in the Sonoma Coast AVA with eighty commercially-producing vineyards cultivating 4,000 acres (1,619 ha) and nine bonded wineries. The wind gap in its coastal mountain range funnels cooling breezes and fog east from the Pacific Ocean through the city of Petaluma to San Pablo Bay. A persistent afternoon breeze causes lower grape yields and longer hang time contributes to the AVA vintages' unique flavors and fruit characteristics which defines their character and distinction.
