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 in the state where the AVA is located.
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.

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.

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 is wine made in Sonoma County, California, in the United States.
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 Chalk Hill AVA is an American Viticultural Area (AVA) located in Sonoma County, California. The boundaries of the wine appellation cover the northeast corner of the Russian River Valley AVA. The majority of vineyards are located to the east of U.S. Route 101, near the town of Windsor. The name Chalk Hill comes from the unique volcanic soil of chalky white ash which has shown itself to perform well with planting of white wine varietals like Chardonnay and Sauvignon blanc. The majority of the region's wineries are located on the western slopes of the Mayacamas Mountains.
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 Oakville AVA is an American Viticultural Area located within Napa Valley AVA and centered on the town of Oakville, California. The appellation extends over a flat expanse of well-drained gravel soil between the Vaca and Mayacamas Mountains.

The Diamond Mountain District AVA is an American Viticultural Area located in California's Mayacamas Mountains in the northwest portion of the Napa Valley AVA. The appellation sits at a higher elevation than most of Napa Valley's wine region, resulting in less cool fog coming in from San Pablo Bay, and more direct exposure to sunlight. The soil of this AVA is volcanic and very porous which allows it to cool down quickly despite the increased sunlight.
The Spring Mountain District AVA is an American Viticultural Area located in the Napa Valley AVA in California.

Encompassed within its bounds are about 8,600 acres (3,480 ha), of which about 1,000 acres (400 ha) are planted to vineyards.
