AVA Home | Wine Institute Home Page

The table below summarizes all approved American Viticultural Areas located in California by the counties that they are located in. Many viticultural areas occupy area in more than one county. The county name in the first column is linked to county information on another web site. Official county sites were used whenever we could locate them. Text and PDF versions of the regulations are provided through links to the Government Printing Office databases. Please be patient - it may take a few moments for the page to load. Newer AVA's may not be in the GPO database. Finally, effective dates and acreage are also provided. Clicking on the hyperlinked name will query the U.S. government printing office for the current regulation. Users may want to review the AVA FILES section to obtain the most recent rulemaking history for specific viticultural areas.
