AMERICAN VITICULTURAL AREA
(AVA) is the system of designating and controlling the geography of grapes
grown for wines produced in the United States. According to regulations,
only wines that derive 85% or more of their content from within the boundaries
of a designated AVA may use that AVA name to label the wine. The wine
must also have been made to "conform
to the laws and regulations of the named appellation area governing the
composition, method of manufacture, and designation of wines made in such
place." This clause protects and defers to the authority of each State
to regulate methods of wine production. The AVA system was begun
in 1979, and is still in relative infancy. The very first AVA, approved
in 1980 was Augusta, Missouri. An AVA can be quite large and encompass
portions of several states, such as the largest 26,000-square-mile, 16.5
million-acre Ohio River Valley AVA that includes parts of Indiana, Kentucky,
Ohio and West Virginia. The smallest is the Cole Ranch AVA, which occupies
a mere 150 acres and less than a quarter square mile of Mendocino County,
California. New AVAs are being applied
for and approved each year. The agency that oversees the creation and
adjustment of the AVA system is the Alcohol and Tobacco Tax and Trade
Bureau (TTB), a division of the US Treasury Department. The minimum cost
to establish an AVA is about $15,000. Applicants must provide proof of
geographic and climatic significance and historical precedent for wine
production, in addition to suggesting and mapping the boundaries. An AVA
is not a grade of quality, it merely allows the producers and consumers
to differentiate and authenticate the growing areas.
There are more than 185
approved AVAs, as of August 1, 2005. The
Wine Institute offers some online pages
to answer "what, where, how and why" questions and provide much more detail
and complexity about American Viticultural Areas and their effect on wine
labeling regulations and restrictions. Complete descriptions of the geographic
and topographic characteristics, the climatic influences and predominant
grape varieties planted for most of these AVAs can be found on the Connoisseurs'
Guide to California Wine site. Vestra
offers a wide selection of detailed, full color, glossy, unframed maps
of West Coast AVAs. Created January 29, 2001;
