An American Viticultural Area (AVA) is a designated wine grape-growing region in the United States, providing an official appellation for the benefit of wineries.


The boundaries of AVAs are defined by the Alcohol and Tobacco Tax and Trade Bureau (TTB) of the United States Department of the Treasury. [1]

The TTB defines AVAs at the request of wineries and other petitioners. As of June 2018, there were 242 AVAs in the United States. [2] Before the AVA system, wine appellations of origin in the United States were designated based on state or county boundaries. All of these appellations were grandfathered into federal law and may appear on wine labels as designated places of origin, but these appellations are distinct from AVAs.

AVAs range in size from the Upper Mississippi River Valley AVA at 29,900 square miles (77,000 km2) across four states (Illinois, Iowa, Minnesota, and Wisconsin), [3] to the Cole Ranch AVA in Mendocino County, California, at only 60 acres (24 ha). [4] The Augusta AVA surrounding the area around the town of Augusta, Missouri, was the first recognized AVA, gaining the status on June 20, 1980. [5]


Current regulations impose certain requirements on an AVA:[ citation needed]

  • Evidence that the name of the proposed new AVA is locally or nationally known as referring to the area;
  • Historical or current evidence that the boundaries are legitimate; and,
  • Evidence that growing conditions such as climate, soil, elevation, and physical features are distinctive.

Petitioners are required to provide such information when applying for a new AVA, and are also required to use USGS maps to both describe (using terms from the map) and depict the boundaries.[ citation needed]

Once an AVA is established, at least 85% of the grapes used to make a wine must be grown in the specified area if an AVA is referenced on its label. [6]

State or county boundaries—such as used for Oregon wine or Sonoma County wine—are not defined as AVAs, even though they are used to identify the source of a wine. AVAs are reserved for situations where a geographically defined area has been using the name and it has come to be identified with that area.[ citation needed]

A vineyard may be in more than one AVA. For example, the Santa Clara Valley AVA and Livermore Valley AVAs are located within the territory of the San Francisco Bay AVA, which is itself located within the Central Coast AVA.[ citation needed]
