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 defined by the Alcohol and Tobacco Tax and Trade Bureau (TTB) of the United States Department of the Treasury.^[1] As of May 2024, there are 273 recognized AVAs in 34 states^[2]—several of which are shared by two or more states. Over half (152) of the AVAs are in California.

American Viticultural Areas range in size from the Upper Mississippi River Valley AVA at 29,900 square miles (77,000 km²) across four states, to the Cole Ranch AVA in Mendocino County, California, at only 62 acres (25 ha). The Augusta AVA near the town of Augusta, Missouri, was the first recognized AVA, gaining the status on June 20, 1980.^[3]
