Leona Valley AVA

Leona Valley AVA sits in the northeastern corner of Los Angeles County, roughly 40 to 50 miles inland from the Pacific Ocean. The valley is narrow, approximately one mile wide, and stretches 25 miles in length. It is surrounded by the Angeles National Forest and the Sierra Pelona Mountains, and is separated from the neighboring Antelope Valley by Portal Ridge. The San Andreas Fault runs through the region, contributing to the notable variety and mineralogy of the soils found throughout the valley.

• Located within the South Coast AVA and Los Angeles County
• Surrounded by Angeles National Forest and Sierra Pelona Mountains
• Separated from Antelope Valley by Portal Ridge
• San Andreas Fault influences soil composition throughout the valley

The climate in Leona Valley is a hot, dry high desert, moderated significantly by the region's altitude. The San Gabriel Mountains create a rain shadow effect, limiting precipitation and concentrating heat during the day. Average heat summation reaches 4,060 degree days, placing the valley in UC Davis Region V. Despite the intense daytime heat, evenings cool dramatically, with diurnal temperature swings reaching up to 50 degrees Fahrenheit. This contrast slows ripening and preserves natural acidity in the grapes. Soils are primarily alluvial, dominated by the Hanford-Ramona-Greenfield association, featuring loamy sand to loam surface layers. Areas around Elizabeth and Hughes Lakes contain soils with higher clay content.

Winemaking in Leona Valley dates back to the late 1800s, when the Ritter family established Belvino Vineyards, one of the valley's earliest commercial operations. The region produced wines of notable quality during this pre-Prohibition era. The arrival of Prohibition in 1920 brought wine production to a halt, and the industry did not revive for nearly a century. The modern era began in 2001 when Reynolds Family Estate planted vineyards on their property. Leona Valley received its official AVA designation on October 28, 2008. Remarkably, some 100-year-old vines planted before Prohibition still survive, producing Mission and Zinfandel grapes.

• Pre-Prohibition winemaking began in the late 1800s, led by the Ritter family's Belvino Vineyards
• Prohibition (1920-1933) ended commercial wine production in the valley
• Modern revival started in 2001 with Reynolds Family Estate's vineyard plantings
• AVA designation granted October 28, 2008
• Centenarian Mission and Zinfandel vines from the pre-Prohibition era remain productive

Leona Valley grows a wide range of varieties suited to its extreme diurnal climate. Red varieties include Syrah, Zinfandel, Cabernet Sauvignon, Cabernet Franc, Petite Verdot, Malbec, and Sangiovese. Chardonnay and Pinot Noir represent the white and cool-climate red categories respectively. Commercial production remains small, concentrated on approximately 20 acres at Reynolds Family Vineyard, with additional Pinot Noir plantings on the Donato Vineyards property. Notable producers include Leona Valley Winery, Reynolds Family Vineyard, and Donato Vineyards. The combination of high altitude and Region V heat yields balanced wines with both ripe fruit character and preserved acidity.
