The Texas High Plains AVA is an American Viticultural Area located on the Llano Estacado region of Texas.[3] The appellation is the second largest American Viticultural Area in Texas, and covers an area of over 270,000 acres (422 sq mi). Most of the vineyards are on flat terrain at elevations between 3,000 feet (914 m) and 4,000 feet (1,219 m) above sea level. The Texas plains can be extremely dry, so most vineyards are irrigated with water from the Ogallala Aquifer.[2] The hardiness zones are 7a and 7b.[4]
