Mesilla Valley AVA

The Mesilla Valley takes its name from a Spanish phrase meaning 'little table,' coined by explorer Don Juan de Oñate in 1598. Viticulture in the broader region dates to 1650, when grapes were grown near El Paso for sacramental wines. Plantings did not reach the Mesilla Valley itself until the early 20th century near Doña Ana, followed by a revival of interest in the 1960s. The area also has a notable connection to the global phylloxera crisis: Texas viticulturist Thomas Volney Munson identified Vitis berlandieri as a phylloxera-resistant rootstock, a discovery tied to this broader region.

• Named by Don Juan de Oñate in 1598; 'mesilla' means 'little table' in Spanish
• Sacramental wine production near El Paso documented from 1650
• Commercial grape growing revival began in the 1960s
• Designated AVA on February 14, 1985, as the 100th AVA in the United States

Mesilla Valley sits at 3,700 to 4,200 feet above sea level, with the Organ Mountains rising to the west. The climate is arid continental, accumulating over 4,000 degree-days annually, with a mean annual temperature of 60.8°F. Summer daytime highs exceed 100°F, yet nights cool sharply, producing a diurnal swing of roughly 33°F that retains acidity in the grapes. Annual rainfall totals just 10 inches, making Rio Grande irrigation essential. Spring winds can be damaging, and nearby pecan orchards serve as natural windbreaks. Soils are primarily alluvial, featuring the Glendale-Harkey series with sand, loam, and clay deposited from surrounding mountain ranges.

• Arid continental climate with over 4,000 degree-days annually
• Only 10 inches of annual rainfall; Rio Grande provides irrigation water
• Glendale-Harkey alluvial soils of sand, loam, and clay
• Pecan orchards nearby buffer vineyards from destructive spring winds

More than 50 grape varieties have been cultivated in the Mesilla Valley over its history. Current plantings focus on both international and Rhône varieties, including Cabernet Sauvignon, Syrah, Merlot, Tempranillo, Mourvèdre, and Zinfandel among reds, and Viognier, Chardonnay, Chenin Blanc, and Gewurztraminer among whites. The extreme diurnal variation is the defining factor in wine style: red wines show fresh tannins and spice rather than jammy overripeness, while whites retain the acidity needed for balance and aromatics.

• Red varieties include Cabernet Sauvignon, Syrah, Tempranillo, Mourvèdre, and Zinfandel
• White varieties include Viognier, Chardonnay, Chenin Blanc, and Gewurztraminer
• Diurnal variation of 33°F is key to acidity retention in both red and white wines
• Over 50 varieties grown historically across the valley

Despite covering 280,000 acres, Mesilla Valley has fewer than 50 acres under vine, making it one of the most sparsely planted AVAs in the United States. It is also the smallest AVA in New Mexico. Notable producers working the region include Fort Selden Winery, Luna Rosa Winery, and Zin Valle Vineyards. The small scale reflects the challenges of farming in an arid, high-desert environment, but those producers who have committed to the valley are demonstrating the potential of its unique terroir.

• Fewer than 50 acres of vineyards planted within 280,000 total acres
• Smallest AVA in New Mexico
• Notable producers: Fort Selden Winery, Luna Rosa Winery, and Zin Valle Vineyards
• Straddles the Rio Grande, with the majority in New Mexico and a small portion in western Texas
