Texas Davis Mountains AVA

The Davis Mountains take their name from Jefferson Davis, who was stationed in the area in the 1850s. The mountains themselves were formed approximately 35 million years ago by volcanic activity that also shaped the front range of the Rocky Mountains. Modern viticulture in the region began in the 1970s when Gretchen Glasscock planted the first vineyard. The AVA was officially established on March 11, 1998, becoming the 155th American Viticultural Area in the United States and Texas' seventh AVA. It holds the distinction of being the last AVA recognized in the 20th century.

• Named for Jefferson Davis, stationed in the region in the 1850s
• Mountains formed by volcanic activity approximately 35 million years ago
• Gretchen Glasscock planted the first vineyard in the 1970s
• Designated AVA #155 on March 11, 1998, the last AVA of the 20th century

The Davis Mountains AVA sits within the larger Trans-Pecos region of Texas and spans 270,000 acres across the second-highest mountain range in the state. Elevations range from 4,500 to 8,300 feet, creating a continental climate with cool summers relative to the surrounding Chihuahuan Desert. Daytime summer temperatures can reach 100°F or higher, but significant diurnal temperature variation allows grapes to retain their natural acidity. Winter and spring temperatures fluctuate between 30 and 70°F. Annual rainfall at higher elevations reaches 16-20 inches, though irrigation remains necessary throughout the AVA.

• Elevation ranges from 4,500 to 8,300 feet, making it Texas' highest-elevation AVA
• Continental climate with significant diurnal variation preserving natural grape acidity
• Annual rainfall of 16-20 inches at higher elevations; irrigation required
• Functions as a 'mountain island' with cooler, wetter conditions than the surrounding desert

The soils of the Davis Mountains AVA reflect the region's volcanic origins. Granitic, porphyritic, volcanic, and limestone materials all contribute to a well-drained profile with a slightly acid to slightly alkaline pH ranging from 5.5 to 7.0. Only 50 to 100 acres are currently under vine, with three vineyards operating in the southern foothills. The leading varieties include Cabernet Sauvignon, Sauvignon Blanc, Merlot, Chenin Blanc, Zinfandel, and Portuguese red varieties suited to the warm days and cool nights.

• Soils are granitic, porphyritic, volcanic, and limestone-derived, with excellent drainage
• pH ranges from 5.5 to 7.0, slightly acid to slightly alkaline
• 50-100 acres under vine; three vineyards operating in the southern foothills
• Cabernet Sauvignon, Merlot, and Portuguese varieties are among the key plantings

The Davis Mountains AVA produces dry table wines and port-style fortified wines. The combination of volcanic soils, high elevation, and strong diurnal shifts yields age-worthy Bordeaux-style reds with intense character. Notable producers include Château Wright Winery and Vineyard, operating the Blue Mountain Trail Vineyard; Sharp Family Vineyards at the Vineyard at Blue Mountain; and Alta Marfa. The small scale of production reflects the AVA's frontier status as one of Texas' most distinctive and least-planted wine regions.

• Specialty in dry table wines and port-style fortified wines
• Bordeaux-style reds are age-worthy with intense character
• Key producers: Château Wright, Sharp Family Vineyards, and Alta Marfa
• Small total production reflects only 50-100 acres under vine across the AVA
