An American Viticultural Area (AVA) is a designated wine grape-growing region in the United States, providing an official appellation for the mutual benefit of wineries and consumers. Winemakers frequently want their consumers to know about the geographic pedigree of their wines, as wines from a particular area can possess distinctive characteristics. Consumers often seek out wines from specific AVAs, and certain wines of particular pedigrees can claim premium prices and loyal customers. If a wine is labeled with an AVA, at least 85% of the grapes that make up the wine must have been grown in the AVA, and the wine must be fully finished within the state where the AVA is located.
The Ramona Valley AVA is an American Viticultural Area located 28 miles (45 km) northeast of the city of San Diego in San Diego County, California, centered on the community of Ramona. It was designated the 162nd American Viticultural Area in January, 2006 by the United States Department of the Treasury Alcohol and Tobacco Tax and Trade Bureau, which recognized the area for its distinctive microclimate, elevation, and soil attributes. Approximately 89,000 acres (360 km2) in area, it is 14.5 miles (23.3 km) long and 9.5 miles (15.3 km) wide. Geographically, the Ramona Valley is described as being a broad, flat valley ringed by hills and mountains that isolate it from the surrounding areas. The valley has an average vineyard elevation of 1,400 feet (430 m) and an annual average rainfall of 16.5 inches (41.9 cm).
Santa Maria Valley is an American Viticultural Area (AVA) which straddles the boundary of Santa Barbara and San Luis Obispo counties in California's multi-county Central Coast AVA. It was established on August 5, 1981, by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) as California's second oldest AVA. A portion of the AVA crosses the Cuyama River into the southernmost corner of San Luis Obispo County. The east–west orientation of the 152.3 square miles with a wide, open valley and rolling hills means cool winds and fog flow in freely from the Pacific Ocean, settling most noticeably in lower-lying areas. The result is a mild Mediterranean climate that lengthens the growing season and contributes to the eventual sugar/acid balance in the grapes from Santa Maria Valley's 7,500 acres (3,000 ha) cultivated vineyards. On January 28, 2011, the AVA was granted an 29.4 square miles expansion to its southern boundary.

In 2002, the area included in the AVA was expanded by 93,500 acres (37,800 ha) along the southern and western portions of the original AVA boundaries in San Joaquin County. The appellation includes land in southern Sacramento County and northern San Joaquin County. It is bounded on the west by Interstate Highway 5 and to the east by the political borders for the adjacent El Dorado, Amador, and Calaveras Counties.
Paso Robles is the third American Viticultural Area (AVA) located in San Luis Obispo (SLO) County, California. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury on November 3, 1983 based on a petition submitted by Martin Brothers Winery. The area 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.
The Cole Ranch AVA is an American Viticultural Area located in Mendocino County, California. At less than a quarter of a square mile, it is the smallest appellation in the United States. The AVA is located between the Russian River and Anderson Valley. All planted land in the appellation is owned by one party. Grapes are sold to several wineries. Cabernet Sauvignon, Merlot Pinot Noir and Riesling are the most popular planting. Cole Ranch is located within three larger appellations - Mendocino AVA, Mendocino County, and the North Coast AVA.
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.
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 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. The Mendocino Ridge AVA lands are above the Anderson Valley and Mendocino appellations. The Mendocino Ridge viticultural area boundary encompasses 262,400 acres, but the actual viticultural area contains only 87,466 acres. Of these, approximately 1,500 to 2,000 acres are suitable for vineyards. The loczl hillsides 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.
The San Lucas AVA is an American Viticultural Area located in Monterey County, California. It is located at the southern end of Salinas Valley, shares an eastern border with the Chalone AVA, and is bordered on the west by the Santa Lucia Range foothills.

The San Pasqual Valley AVA is an American Viticultural Area in northern San Diego County, California. It is located in the San Pasqual Valley of the Peninsular Ranges, in Southern California.
Santa Cruz Mountains AVA is an American Viticultural Area (AVA) centered on the Santa Cruz Mountains. Its territory spans three California counties, Santa Clara, Santa Cruz and San Mateo and was established January 4, 1982 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury. Santa Cruz Mountains AVA was among the first AVA to be defined by its mountainous 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 along the ridge crest line at 3,000 feet (910 m) elevation plus.
The Bennett Valley AVA is an American Viticultural Area located in Sonoma County, California. The boundaries of this appellation lie completely within the North Coast AVA, almost completely within the Sonoma Valley AVA and overlaps into some areas of the Sonoma Coast AVA and Sonoma Mountain AVA. The region was granted AVA status on December 23, 2003 following the petition of Matanzas Creek Winery. The AVA is surrounded to the south, east and west by the Sonoma Mountains and to the north by the city of Santa Rosa, California. The region receives a moderating effect on its climate from Pacific Ocean through the cool coastal fogs and breeze that creep into the area from the southwest through Crane Canyon between Sonoma Mountain and Taylor Mountain. Barbera, Cabernet Sauvignon, Cabernet Franc, Chardonnay, Grenache, Merlot, Pinot noir, Sauvignon blanc and Syrah are the leading grape varieties planted.
The North Coast AVA is an American Viticultural Area in the state of California that encompasses grape-growing regions in six counties located north of San Francisco: Lake, Marin, Mendocino, Napa, Sonoma, and Solano. This large appellation covers over 3,000,000 acres (5,000 sq mi) and includes a number of smaller sub-appellations that all share the common ecology trait of weather affected by the fog and breezes off the Pacific Ocean.
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 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.
The Sonoma Coast AVA is an American Viticultural Area in Sonoma County, California, United States containing more than 500,000 acres (2,000 km2), mostly along the coastline of the Pacific Ocean. It extends from San Pablo Bay to the border with Mendocino County. The appellation is known for its cool climate and high rainfall relative to other parts of Sonoma County. The area has such a broad range of microclimates that petitions have been made to the United States Department of the Treasury Alcohol and Tobacco Tax and Trade Bureau for the creation of sub-AVAs such as the Fort Ross-Seaview AVA which was approved in December 2011.
The Mendocino AVA is an American Viticultural Area within the larger North Coast AVA. Several small AVAs are nested inside the Mendocino appellation and it roughly encompasses Mendocino County, California. The Mendocino AVA is known for the cultivation of Mediterranean climate grapes including Carignan, Charbono, Grenache, Petite Sirah, Syrah and Zinfandel. Because of its cooler climate, the Anderson Valley is known for its Pinot noir and sparkling wine production. Many wineries in nearby Sonoma and Napa counties purchase Mendocino grapes to blend into wines labeled with other appellations.

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.
