Abbreviation for "American Viticultural Area" (also "Approved Viticultural Area"), the appellation system commonly used in the USA. It was introduced at the urging of particularly California grape growers. The classification system developed in California in the 1940s based on climatic zones had proven to be not particularly effective. Starting in 1970, all U.S. states were investigated regarding their geographical characteristics at the request of the U.S. federal government by the then agency BATF (now TTB = Alcohol and Tobacco Tax and Trade Bureau). This included the suitability of certain regions for specific grape varieties.

In 1978, some geographical areas were classified for the first time, thus creating the conditions for a origin based on the French Appellation d’Origine Protégée. The first still very inconsistent systems were aligned with political state or county borders.
