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.
