Texas High Plains AVA
Texas High Plains is an American Viticultural Area (AVA) located on the Llano Estacado region of northwestern Texas. It was established as the nation's 144th and Texas' sixth AVA on March 2, 1993, by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing a petition submitted by Clinton M. McPherson, on behalf of High Plains vinegrowers, proposing a viticultural area in the Texas Panhandle to be known as "Texas High Plains." The wine appellation is the second largest AVA in Texas encompassing over 8 million acres (12,500 sq mi). Most of the vineyards are on flat terrain at elevations between 3,000 and 4,000 feet (910–1,220 m) above sea level.
The viticultural area also intensively cultivates cotton, sorghum and wheat as the predominant crops, irrigated from the Ogallala Aquifer. The elevations are between 3,000 and 4,000 feet (910–1,220 m) above sea level. At the outset, vineyards cultivated approximately 2,000 acres (810 ha) with a growing interest in viticulture. There were four wineries active within the viticultural area and nearly half of all commercial wine grapes grown in Texas are cultivated in the Texas High Plains. There are currently 3,700+ acres (1,500+ ha) of cultivation in the High Plains on 18 vineyards sourcing 15 wineries. The High Plains can be extremely dry, so vineyards are also irrigated from the Ogallala Aquifer. The hardiness zones are 7a, 7b and 8a.
