There are currently 276 American Viticultural Areas (AVAs) in the world. As an AVA is a specific designation for wine grape-growing regions in the United States, these 276 AVAs are located exclusively within the U.S. borders.
Understanding American Viticultural Areas (AVAs)
An American Viticultural Area (AVA) is a designated wine grape-growing region in the United States distinguishable by its geographic features. The Alcohol and Tobacco Tax and Trade Bureau (TTB) defines AVA boundaries. These boundaries help identify grape origins for labeling purposes, ensuring consumers understand where their wine comes from based on specific geological and climatic characteristics.
Current AVA Statistics
The United States is home to a robust and growing number of AVAs, spanning a significant portion of the country's winemaking states.
| Statistic | Number | Details |
|---|---|---|
| Total AVAs | 276 | Currently recognized American Viticultural Areas |
| States with AVAs | 34 | Number of U.S. states where AVAs are established |
| AVAs in California | 154 | Over half of all AVAs are located in California |
California, renowned for its diverse wine industry, accounts for the majority of these designated areas, with 154 AVAs contributing to its prominent status in global wine production.
Historical Context of AVAs
The concept of AVAs was established to provide a system for defining grape origin beyond simple state or county lines.
- The Augusta AVA, located around the town of Augusta, Missouri, holds the distinction of being the first recognized AVA. It officially gained this status on June 20, 1980. This marked a pivotal moment for American winemaking, recognizing the unique terroir of specific regions.
Nested AVAs: A Unique Feature
A distinguishing characteristic of the AVA system is the possibility of nested AVAs. This means that a smaller, more specific AVA can be entirely located within one or more larger AVAs. For example, the Rutherford AVA is nestled within the larger Napa Valley AVA, which itself is part of the even larger North Coast AVA. This hierarchical structure allows for increasingly precise identification of grape origin, reflecting nuanced differences in climate, soil, and topography.
