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.
Carmel Valley is an American Viticultural Area (AVA) located in Monterey County, California, southeast of Carmel-by-the-Sea and it is one of the ten AVAs in the county. Approximately 100 miles (161 km) south of San Francisco, the AVA was recognized by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury on January 13, 1983 after reviewing the petition submitted by Mr. David Armanasco, General Manager of Durney Vineyard, located in Carmel, to propose a viticultural area named “Carmel Valley.”
The Livermore Valley AVA is an American Viticultural Area in Alameda County, California, surrounding the city of Livermore in the Tri-Valley region. Both the AVA and the city are named after Robert Livermore, a landowner whose holdings encompassed the valley. The groundwater basin underlying the valley is the Livermore Basin, the largest sub-unit of which is the Mocho Subbasin. The Livermore Basin is one of five aquifers in the San Francisco Bay Area that supply most of the metropolitan Bay Area population. The entire Livermore Basin aquifer faces a concern over elevated total dissolved solids by the year 2020 due to an expanding human population leading to higher rates of return water flows to the aquifer containing certain salts.
Kathryn Kennedy was a California wine grower, establishing her vineyard during the growth phase in the California wine history known as "The Wine Boom of the early 1970s".

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.
San Francisco Bay is a multi-county American Viticultural Area (AVA) which is centered and surrounds the San Francisco Bay Area of Northern California. It was established on March 22, 1999 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after evaluating the petition submitted by a consortium of nearly 75 growers and vintners led by Wente Bros. to establish the viticultural area known as "San Francisco Bay."

ATF also concluded the established Santa Cruz Mountains viticultural area exhibits features and characteristics unique to its boundaries when compared to the surrounding areas, therefore, it was excluded from the "San Francisco Bay" viticultural area.
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.
