The table below summarizes all approved American Viticultural Areas by size in descending order, starting with the largest. There are some viticultural areas for which we do not have acreage information. Effective dates and acreage are also provided. Clicking on the hyperlinked name will query the U.S. government printing office for the current regulation. Please be patient - it may take a few moments for the page to load. Newer AVA's may not be in the GPO database. Users may want to review the AVA files section to obtain the final rule for these AVA's that were published in the Federal Register.

The table below sorts these areas by their size. There are at least six areas where we do not have data on the area's size; these areas are listed at the bottom of the table and are mentioned here:

AUGUSTA
CIENEGA VALLEY
LOS CARNEROS
NORTH FORK OF ROANOKE
ROGUE VALLEY
SANTA CRUZ MOUNTAINS

The largest area is the OHIO RIVER VALLEY. Next in size is the TEXAS HILL COUNTRY, which spans an area of 15,000 square miles, and is larger in size than New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, Hawaii, New Jersey, Delaware, or Maryland. The smallest area (COLE RANCH) covers a little less than a quarter square mile.
