List of American Viticultural Areas

An American Viticultural Area (AVA) is a designated appellation for American wine in the United States distinguishable by geographic, geologic, and climatic features, with boundaries initially defined by the Bureau of Alcohol, Tobacco and Firearms (ATF), then in 2003 by the Alcohol and Tobacco Tax and Trade Bureau (TTB) of the United States Department of the Treasury.^[1] As of 2026, there are 280 recognized AVAs in 34 states^[2]—several of which are shared by two or more states. Over half (154) of the AVAs are in California.

American Viticultural Areas range in size from the Upper Mississippi River Valley AVA at 19 million acres (29,900 sq mi) across four states, to the Cole Ranch AVA in Mendocino County, California, at only 62 acres (25 ha). The Augusta AVA surrounding the town of Augusta, Missouri, was the first established AVA on June 20, 1980.^[3]
