Use the American Viticultural Area (AVA) Map Explorer to view the boundaries of all established and proposed AVAs. The Map Explorer has information about each AVA, including its state and county, when it was established, what other AVAs it contains or is within, and a link to its codified official boundary description. You can even plot an address on the Map Explorer to see if that location is within an AVA. You can also download "shapefiles" for the various AVAs, which you can use with geographic information system (GIS) software.
