The Texas High Plains AVA is an American Viticultural Area located on the Llano Estacado region of Texas. The appellation is the second largest American Viticultural Area in Texas, and covers an area of over 270000 acre. Most of the vineyards are on flat terrain at elevations between 3000 ft and 4000 ft above sea level. The Texas plains can be extremely dry, so most vineyards are irrigated with water from the Ogallala Aquifer. The hardiness zones are 7a and 7b.

Wineries

There are at least six wineries located within the Texas High Plains AVA, although many wineries outside of the AVA source grapes from the high plains including Caprock Winery (the first publicly held Winery in the state) and Llano Estacado Winery.
