The Texas Davis Mountains AVA is an American Viticultural Area located in the Trans-Pecos region of West Texas. Surrounded by the Chihuahuan Desert, the appellation takes advantage of cooler elevation and lower annual rainfall in the Davis Mountains. The land within the boundaries of the AVA ranges between 4,500 feet (1,372 m) and 8,300 feet (2,530 m) above sea level. The soil is primarily granitic, porphrytic, and volcanic in nature.
