Yakima Valley is the first American Viticultural Area (AVA) established within Washington state, gaining the recognition on May 4, 1983. Within the vast Columbia Valley AVA, Yakima Valley appellation cultivates more than 53,000 acres (21,448 ha) giving the region the largest concentration of wineries and vineyards in the state. The most widely planted varietals in the area are Chardonnay, Riesling, Merlot, Cabernet Sauvignon, Pinot gris, and Syrah. Nearly 40% of Washington's annual wine production is made from Yakima Valley grapes. In addition to grapes, the Yakima Valley is also home to several fruit orchards growing apples, cherries, nectarines, peaches, pears and plums. Around the town of Zillah, there is the Zillah Fruit Loop driving tour through the area's orchards and vineyards. The area is also home to nearly 80% of the US hop production. In July 2024, the Yakima Valley was named best wine region in the U.S. by readers of USA Today.
Walla Walla Valley is an American Viticultural Area (AVA) located within Washington state and extending partly into the northeastern corner of Oregon. The wine region is entirely included within the larger Columbia Valley AVA. In addition to grapes, the area produces sweet onions, wheat and strawberries After the Yakima Valley AVA, the Walla Walla AVA has the second highest concentration of vineyards and wineries in Washington State. Walla Walla hosts about 140 wineries. The area was recognized on March 7, 1984 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Mr. Richard L Small, President of the Walla Walla Valley Winegrowers Association, for the establishment of a viticultural area in southeast Washington and northeast Oregon, east of Lake Wallula, to be known as "Walls Walls Valley." At the time, Walla Walla Valley viticultural area was approximately 178,560 acres (279 sq mi) with two bonded wineries and about 60 acres (24 ha) from several vineyards.
Knights Valley is an American Viticultural Area (AVA) located in Sonoma County, California. As one of the five original viticultural areas in the county, Knights Valley was established on October 21, 1983 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by The Knights Valley Wine-Growers Committee, an organization of grape/wine industry members, signed by 16 persons, to establish a viticultural area in northeastern Sonoma County named "Knights Valley." The area encompasses approximately 36,240 acres (57 sq mi) with over 30 growers cultivating 2,000 acres (809 ha) under vine. In the easternmost Sonoma County region, Knights Valley has the warmest climate in the county. The northernmost section of the boundary line runs slightly to the north of Pine Mountain; the southernmost section of the boundary line borders the petrified forest area immediately to the north of Porter Creek. The Sonoma County line bordering Lake County and Napa County forms the eastern section of the boundary of the viticultural area. The easternmost section of the boundary line abuts the boundaries for the Alexander Valley and Chalk Hill viticultural areas. The appellation is the border separating Sonoma County from the Napa Valley.
Temecula Valley is an American Viticultural Area (AVA) in the Temecula Valley, located in southwestern Riverside County, California against the eastern slopes of the Santa Ana Mountains. It was initially established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury as "Temecula" on October 23, 1984 after reviewing petitions submitted by the Rancho California/Temecula Winegrowers Association and Callaway Vineyard and Winery, Temecula, California in 1981. The petitioners originally proposed to establish a viticultural area in Riverside County to be named "Temecula," "Murrieta," and "Rancho California" but the ATF did not adopt it. In 2004, it was renamed "Temecula Valley" by the Alcohol and Tobacco Tax and Trade Bureau (TTB), approving the 2001 petition submitted by the Temecula Valley Winegrowers Association. The petition stated the name change would provide a more accurate description of the Temecula geography and greater clarity as to its location for wine consumers and the public. The petition did not request any change to the established AVA boundaries. This was the first AVA to change its name after the initial approval. Temecula Valley encompasses 33,000 acres (52 sq mi) and 5,000 acres (8 sq mi) is located in a "protected" area referred to as the Citrus/Vineyard Zone. This area is generally located in and around the Rancho California Road area within Riverside County. County guidelines strictly enforce the number of acres needed to build a winery, lodging and other limited housing and commercial ventures.
Paso Robles is the third American Viticultural Area (AVA) located in San Luis Obispo (SLO) County, California. The area was established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury on October 4, 1983 after reviewing the petition submitted by Martin Brothers Winery accompanied by 51 signatures of local grape-growers and wineries proposing a viticultural area named "Paso Robles." The AVA encompasses 609,673 acres (953 sq mi) with approximately 18,500 acres (7,487 ha) cultivated with wine grapes known for their heritage varietal Zinfandel, Cabernet Sauvignon, and Rhône-style wines.
Cole Ranch is an American Viticultural Area (AVA) located in Mendocino County, California. The small viticultural area was established on April 15, 1983 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by the proprietor of Cole Ranch in Ukiah, California. At less than a quarter of a square mile, it is the smallest appellation in the United States. The viticultural area is located in a small, narrow mountain valley west of Hwy 101 on the 500 acres (0.78 sq mi) ranch originally owned by the Cole family. The valley is approximately one mile in length and a half mile across at its widest point tucked into the high hills ranging from 1,400 to 1,600 ft (427–488 m) in elevation. The AVA is located between the Russian River and Anderson Valley. Several prominent wineries source grapes from Cole Ranch including Fetzer Vineyards and Chateau St. Jean. Cabernet Sauvignon, Merlot Pinot Noir and Riesling are the most popular planting. Cole Ranch viticultural area is sub-region of Mendocino AVA. As of 2024, the Sterling family, proprietors of the Esterlina Winery located at Philo, owns the vineyard acreage.
Central Coast is a vast American Viticultural Area (AVA) that spans along the Central California Pacific coastline from the San Francisco Bay Area south through Monterey, San Luis Obispo and Santa Barbara Counties. It was established on November 25, 1985 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Taylor California Cellars, a winery in Gonzales, California, to establish the "Central Coast" viticultural area. The boundaries of the Central Coast, which have been expanded twice, includes portions of six counties where approximately 100,000 acres (40,469 ha) cultivated with Chardonnay being more than half of the varietal. Within the multi-county AVA are numerous established appellations that share the same maritime climate produced by the Pacific Ocean.
Mendocino Ridge is a coastal, cool climate and high altitude American Viticultural Area (AVA) located entirely within the coastal zone of Mendocino County, California. The viticultural area was established on October 27, 1997 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Mr. Steve Alden on behalf of the Mendocino Ridge Quality Alliance proposing a viticultural area named "Mendocino Ridge." The boundaries of the 262,400 acres (410 sq mi) AVA encompass the coastal ridges at or above 1,200 ft (366 m) in elevation adjacent to the Pacific Ocean that reach inland toward the Anderson Valley. Roughly 36 mi (58 km) of the southernmost portion of the Mendocino coastline forms the AVA western border, with the Sonoma County line as the southern boundary, the Navarro River is the northern boundary and Anderson Valley outlines the inland boundary running northwest–southeast. Mendocino Ridge is essentially a northern extension of the Sonoma Coast viticultural area. Mendocino Ridge AVA designation is unique by its elevation where vineyards lie at or above 1,200 ft (366 m). This means Mendocino Ridge is the only non-contiguous AVA in the United States. The Mendocino Ridge AVA has been nicknamed "Islands in the Sky," because the thick fog moving inland from the Pacific Ocean blankets the coast and the valleys between the ridge tops, making the tops of the mountains, where the vinyards lay, look like islands protruding from a sea of fog. Mendocino Ridge AVA lies above the Anderson Valley and Mendocino appellations. The Mendocino Ridge viticultural area contains approximately 1,500 to 2,000 acres (607–809 ha), about 2% of the total acreage, that are suitable for vineyards. The local hillsides are very steep and covered with timber, making them unfit for viticulture. Estimates of planted acres range from 233 to 410, which accounts for about 0.3% of the total area.
Arroyo Grande Valley is an American Viticultural Area (AVA) located in San Luis Obispo County, California approximately 12 miles (19 km) southeast of the county seat San Luis Obispo. Arroyo Grande Valley was recognized on February 5, 1990 by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) as the state's 60th AVA based on the petition filed in 1987 by Don Talley of Talley Vineyards and William S. Greenough of Saucelito Canyon Vineyard for the establishment of the "Arroyo Grande Valley" viticultural area in San Luis Obispo County. The 16 miles (26 km) long, approximately 67 square miles valley appellation benefits from its east-northeast orientation allowing the breeze from the Pacific Ocean to moderate the climate of the area. The valley is divided by a fog line produced by the cool maritime layer where Zinfandel, Petite Sirah and Rhône varietals are grown on the higher elevations near Lopez Lake and the cooler mid-valley vineyards being home to Chardonnay and Pinot noir. On April 8, 2022, the Alcohol and Tobacco Tax and Trade Bureau (TTB) approved the designation of the expansive San Luis Obispo (SLO) Coast AVA overlapping the boundaries of Edna Valley and Arroyo Grande Valley viticultural areas because they share common features. However, these two previously established areas still have unique characteristics to retain their viticultural area distinctions within SLO Coast. Edna Valley lies immediately to the northwest, the Los Padres National Forest straddles the north leg boundary, the Santa Maria Valley AVA lies to the southeast of Arroyo Grande Valley, and the Pacific Ocean communities of Oceano, Grover City and Arroyo Grande abut its southwestern border.
Edna Valley is an American Viticultural Area (AVA) located in San Luis Obispo (SLO) County, California encompassing the rural town of Edna which is 9 miles (14 km) southeast of the county seat San Luis Obispo and north of the small coastal town Arroyo Grande. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) as the county's first AVA within California’s multi-county Central Coast AVA effective May 12, 1982. It became an sub-appellation of the county’s newest San Luis Obispo Coast viticultural area since April 2022. The valley is diagonally flanked by Lake Lopez to the south and Islay Hill to the north. The elongated valley extends along a northwest-southeast axis bordered to the west by the Santa Lucia Mountains and surrounded by volcanic mountains and characterized by black humus and clay-rich soils. With moderate sunshine, cool maritime fog, and rich oceanic and volcanic soils, the Edna Valley appellation has California's longest growing season. The valley is kept cool by breezes from the Pacific Ocean and morning fog. The extended growing season allows complex flavors to develop in the grapes.
The 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.
Fiddletown is an American Viticultural Area (AVA) in Amador County, California, United States. The area was established on November 3, 1983 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted from the Fiddletown Wine Grape Growers in Amador County to establish a viticultural area to be known as "Fiddletown." The region was first settled in 1849, during the California Gold Rush. Settlers who stayed in the area eventually planted grape vines, which became abundant by the end of the nineteenth century. Most of the vineyards in the Fiddletown AVA are located in the south and west portion of the region on Sierra Nevada slopes between 1,500 to 2,500 feet (457–762 m) above sea level. About 20% of the wine produced in Amador County comes from Fiddletown viticultural area.
Monterey is an American Viticultural Area (AVA) located in eastern Monterey County, California. It was recognized on July 16, 1984 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by the Monterey Winegrowers Council to establish the "Monterey" viticultural area. The designated area within the multi-county Central Coast AVA expands almost the entire length of the county from the Monterey Bay southern shoreline to the Salinas river valley framed by the Santa Lucia, Sierra de Salinas and Gabilan Ranges stretching north-south for about 100 miles (160 km) from Watsonville to its southern point, abutting the town of Paso Robles in San Luis Obispo County. Monterey AVA expands approximately 360,000 acres (560 sq mi) with about 40,000 acres (16,000 ha) of cultivated vineyards. The AVA includes parts of the Carmel and the Salinas valleys containing five smaller American viticultural areas: Arroyo Seco, Hames Valley, San Bernabe, San Lucas and Santa Lucia Highlands. The northern portion is a cool growing region with a very long growing season. Daytime temperatures rarely exceed 75 °F (24 °C) in most parts of the region, although the southern segments of the AVA can measure 100 °F (38 °C) at times. The soil is sandy loam and most regions require irrigation from the Salinas River.
Hames Valley is an American Viticultural Area (AVA) in Monterey County, California a few miles from its southern border with San Luis Obispo (SLO) County. The state's 67th appellation was established on April 15,1994 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by Mr. Barry C. Jackson of the Harmony Wine Company on behalf of Valley Farm Management, Soledad, California, and Mr. Bob Denney & Associates, Visalia, California to establish a viticultural area within Monterey County known as "Hames Valley."
Sta. Rita Hills is an American Viticultural Area located in Santa Barbara County, California within the vast Santa Ynez Valley. The approximately 30,720 acres (48 sq mi) area was established on May 31, 2001 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Department of the Treasury after reviewing the petition submitted by J. Richard Sanford and drafted by Wesley D. Hagen, on behalf of viticulturists and vintners working in Santa Barbara County. The petition was signed by 22 people, 14 of whom are local wine grape growers, to establish a viticultural area encompassed by, but separate from, the Santa Ynez Valley AVA to be named "Santa Rita Hills."
The Santa Ynez Valley AVA is an American Viticultural Area located in Santa Barbara County, California established on May 16, 1983 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after approving a petition submitted by Firestone Vineyard, a bounded winery in Los Olivos, California. It is part of the larger Central Coast AVA, and contains the greatest concentration of wineries in Santa Barbara County. The valley is formed by the Purisima Hills and San Rafael Mountains to the north and the Santa Ynez Mountains to the south creating a long, east-west corridor with very cool temperatures on the coast that become progressively warmer inland. The Santa Ynez River flows east to west on the valley floor toward the Pacific Ocean. As of 2021, the Santa Ynez Valley contains four other established viticultural areas: Sta. Rita Hills on its western boundary; Ballard Canyon and Los Olivos District occupying the center region; and Happy Canyon on the eastern border. Chardonnay is the most planted grape variety in the cooler, western portion of the valley while Rhône varieties thrive in the eastern locales.
Adelaida District is an American Viticultural Area (AVA) located on the northwest portion of the Paso Robles AVA in San Luis Obispo County, California.
