The Texas Hill Country AVA is an American Viticultural Area located in the Texas Hill Country north of San Antonio and west of Austin, Texas. The appellation is the third largest American Viticultural Area in geographic area behind the Upper Mississippi River Valley AVA and Ohio River Valley AVA, covering an area of over 9000000 acre. Established in 1991, it is the southernmost AVA. Today, there are around 80 wineries/vineyards. Despite the cultural influence of the local Texas German population, most of the grape varietals grown in the Texas Hill Country originate from France, Italy, or Spain rather than the cooler climate of Germany.
