Livermore Valley AVA

Spanish missionaries planted the first wine grapes in Livermore Valley in the 1760s, and by the 1840s California pioneers, including Robert Livermore himself, were establishing the first commercial vines. The valley's modern wine era began in earnest in the early 1880s when German immigrant C.H. Wente, Irish immigrant James Concannon, and Maine-born journalist Charles Wetmore recognized the region's winegrowing potential and founded their wineries. Wetmore's Cresta Blanca gained international recognition in 1889, while Wente and Concannon survived Prohibition and went on to shape California viticulture through the 20th century. Most Livermore wineries closed during Prohibition, but Wente and Concannon both found legal means to continue production, preserving the valley's wine heritage.

• Spanish missionaries planted the first wine grapes in Livermore Valley in the 1760s; Robert Livermore planted the first commercial vines in the 1840s
• Charles Wetmore founded Cresta Blanca in 1882, planting cuttings of Sauvignon Blanc sourced from Château d'Yquem; the 1884 vintage won the Grand Prize at the 1889 Paris Exposition, the first American wine ever to win a prize in France
• Wente Vineyards survived Prohibition by producing sacramental and medicinal wine, selling grapes to home winemakers, and diversifying into cattle ranching, never missing a vintage
• Cresta Blanca was sold to Schenley Industries in 1941, closed in 1965, and the land was subsequently purchased by the Wente family in 1981 and revitalized as the Sparkling Cellars

Livermore Valley's east-west orientation is unique among northern California wine regions, stretching approximately 15 miles from east to west and 10 miles from north to south, surrounded by coastal range mountains and foothills. This alignment channels cool marine fog and afternoon breezes from the Pacific Ocean and San Francisco Bay directly into the valley, moderating summer heat and creating the warm days and cool nights that allow grapes to develop full ripeness while retaining natural acidity. The valley sits roughly 30 miles east of San Francisco Bay in Alameda County. Its gravelly, well-drained alluvial soils naturally restrict vine vigor and concentrate flavors in the fruit.

• East-west orientation is unique among northern California wine regions, allowing coastal fog and marine breezes to funnel directly inland from San Francisco Bay every afternoon and evening
• Most vineyard acreage falls in UC Davis Region III by the heat summation system, with a small portion classified as Region II; the reliable onshore breeze produces large diurnal temperature swings
• Primary soils are the Yolo-Pleasanton association, with the Livermore gravelly and very gravelly series prominent in the southern valley; well-drained gravelly soils restrict vine vigor and intensify flavors
• The valley is located in Alameda County, within the San Francisco Bay AVA and, in turn, the larger Central Coast AVA

Cabernet Sauvignon, Petite Sirah, and Merlot are the most-planted red varieties in Livermore Valley, while Chardonnay and Sauvignon Blanc lead among whites. The region's pioneering role in varietal wine labeling is unmatched in California: Wente released the first varietal-labeled Sauvignon Blanc in the United States under the Valle de Oro label in 1932 and the first varietal-labeled Chardonnay in 1936. Concannon released the country's first varietal-labeled Petite Sirah from its 1961 vintage in 1964. The original Semillon and Sauvignon Blanc plantings in Livermore trace their cuttings to Château d'Yquem, and Bordeaux varieties remain a regional signature alongside growing Rhone and Italian plantings.

• Concannon Vineyard released the first varietally labeled Petite Sirah in the United States in 1964 from the 1961 harvest; Jim Concannon, third-generation vintner, is recognized as the 'Father of Petite Sirah'
• Ernest Wente imported Chardonnay cuttings from the F. Richter Nursery in Montpellier, France in 1912, in collaboration with UC Davis professor Leon Bonet; the resulting Wente Clone now covers over 75% of California's Chardonnay plantings
• Herman and Ernest Wente released the first varietally labeled Chardonnay in the United States as a 1936 vintage, following the first varietal Sauvignon Blanc launched under the Valle de Oro label in 1932
• Cabernet Sauvignon, Merlot, Cabernet Franc, Sauvignon Blanc, and Petite Sirah remain the dominant varieties, with expanding plantings of Rhone, Italian, and Spanish grapes

Wente Vineyards remains the largest producer in Livermore Valley and the oldest continuously operated family-owned winery in the United States, now in its fifth generation and owned by the Wente family. Concannon Vineyard, founded the same year as Wente in 1883, changed ownership several times before being acquired in December 2024 by Lemmons Family Vineyards LLC and Darcie Kent Winery LLC, returning the historic property to family ownership. The region has grown to more than 50 wineries ranging from boutique 100-case producers to large estate operations. Murrieta's Well, a small-lot artisanal brand within the Wente Family Estates portfolio, and McGrail Vineyards, known for acclaimed estate Cabernet Sauvignon, represent the diversity of the current scene.

• Wente Vineyards: established 1883; America's oldest continuously operated family-owned winery; now in its fifth generation; known for the Wente Clone Chardonnay program and estate Cabernet Sauvignon; the estate is California Historical Landmark No. 957
• Concannon Vineyard: established 1883; home of America's First Petite Sirah and Cabernet Clones 7, 8, and 11; acquired in December 2024 by Lemmons Family Vineyards LLC and Darcie Kent Winery LLC, returning to family stewardship
• Murrieta's Well, part of Wente Family Estates, produces small-lot Bordeaux-style blends from Livermore Valley estate vineyards
• McGrail Vineyards, established 2008 on a 25-acre estate planted in 1999, specializes in Cabernet Sauvignon and won Best Red Wine in the United States at the San Francisco Chronicle Wine Competition shortly after opening

Livermore Valley was established as an AVA on August 31, 1982, by the Bureau of Alcohol, Tobacco and Firearms, becoming the nation's nineteenth AVA, the state's thirteenth, and Alameda County's first. The designation was based primarily on the region's distinctive gravelly soils and the marine winds drawn into the valley every afternoon from San Francisco Bay. Wine made from Livermore Valley grapes is also eligible for the San Francisco Bay AVA and Central Coast AVA designations. California law requires that 85% of grapes used in a wine bearing an AVA designation be sourced from that AVA. There are no specific varietal requirements within the Livermore Valley AVA.

• AVA established August 31, 1982; the nineteenth AVA in the United States, the thirteenth in California, and the first in Alameda County; 96,000 acres total
• Designation rests on two distinguishing factors: gravelly Livermore-series soils with excellent drainage, and the reliable afternoon and evening marine breezes from San Francisco Bay
• Wine made from Livermore Valley grapes is eligible for three nested appellations: Livermore Valley AVA, San Francisco Bay AVA, and Central Coast AVA
• Concannon Vineyard was one of the first wineries in California to become Certified Sustainable, achieving certification in 2009; Wente Vineyards holds both vineyard and winery certification from the California Sustainable Winegrowing Alliance

Wente Vineyards opened California's first dedicated winery tasting room, marking the beginning of wine tourism in Livermore Valley and setting a model that many California wineries later followed.

The Livermore Valley wine region now hosts more than 50 wineries, ranging from intimate boutique operations to well-known estates, with settings spanning rustic barns to full destination properties with food, music, and events. The region draws visitors from the broader San Francisco Bay Area and beyond, benefiting from its proximity to major urban centers.
