California Wine History

California winemaking began with the Spanish missions. Father Junipero Serra planted the first vineyards at Mission San Diego de Alcala in 1769, and subsequent missions along El Camino Real each maintained vineyards for sacramental wine. The Mission grape (now identified as Listan Prieto/Criolla) dominated plantings. After Mexican secularization of the missions in 1833, commercial viticulture emerged. Jean-Louis Vignes, a Frenchman from Bordeaux, established the first commercial vineyard in Los Angeles in the 1830s, importing European varieties. The Gold Rush of 1849 transformed demand, as miners and settlers created a thirsty market that drove rapid vineyard expansion across Sonoma, Napa, and the Sierra Foothills.

• Father Junipero Serra planted California's first vineyard at Mission San Diego in 1769 using the Mission grape
• Jean-Louis Vignes established California's first commercial vineyard in Los Angeles in the 1830s, importing vines from Bordeaux
• The Gold Rush of 1849 created explosive demand, triggering California's first wine boom
• By the 1860s Sonoma and Napa counties had overtaken Los Angeles as California's leading wine regions

Agoston Haraszthy, a Hungarian immigrant often called the father of California viticulture, imported over 100,000 vine cuttings representing 300 varieties from Europe in the 1850s and 1860s. He founded Buena Vista Winery in Sonoma in 1857, California's first premium winery. Charles Krug established Napa Valley's first commercial winery in 1861, followed by Schramsberg (1862), Beringer (1876), and Inglenook (1879). This golden age was interrupted by phylloxera in the 1880s, which destroyed thousands of acres. The industry rebuilt on resistant rootstock, and by the early 1900s California was producing over 30 million gallons annually. Italian immigrants in Sonoma and the Central Valley built major operations, including Italian Swiss Colony and the Gallo family's early ventures.

• Agoston Haraszthy imported 300+ European grape varieties and founded Buena Vista Winery in Sonoma (1857)
• Charles Krug (1861), Schramsberg (1862), Beringer (1876), and Inglenook (1879) established Napa Valley's winemaking foundation
• Phylloxera devastated California vineyards in the 1880s, forcing widespread replanting on resistant rootstock
• By 1900 California was producing over 30 million gallons of wine annually, dominated by red table wines

The 18th Amendment and Volstead Act (1920) devastated California's wine industry. Of roughly 700 wineries operating before Prohibition, fewer than 140 survived to Repeal in 1933. Survivors like Beaulieu Vineyard (under Andre Tchelistcheff), Beringer, and Concannon relied on sacramental wine permits, home winemaking grape sales (each household could make 200 gallons per year), and grape juice concentrate. After Repeal, the industry struggled. Consumer tastes had shifted toward sweet fortified wines and spirits. It took decades to rebuild quality-focused table wine production. Key figures during this era included Andre Tchelistcheff at Beaulieu Vineyard, who arrived in 1938 and introduced cold fermentation and malolactic fermentation to Napa, and Martin Ray, who championed varietal-labeled wines at his mountaintop estate.

• Prohibition (1920 to 1933) reduced California's ~700 wineries to fewer than 140 survivors
• Home winemaking exemption (200 gallons per household per year) kept grape demand alive during Prohibition
• Andre Tchelistcheff arrived at Beaulieu Vineyard in 1938, introducing cold fermentation and other modern techniques to Napa Valley
• Post-Prohibition recovery was slow: sweet fortified wines outsold dry table wines in California until the mid-1960s

The modern California wine revolution began in the mid-1960s. Robert Mondavi left Charles Krug and founded Robert Mondavi Winery in Oakville in 1966, becoming the first major new Napa Valley winery since Prohibition. Mondavi championed varietal labeling, French oak aging, and winery tourism, setting the template for premium California wine. Other pioneers followed: Warren Winiarski founded Stag's Leap Wine Cellars in 1970, Mike Grgich made wine at Chateau Montelena, and Ridge Vineyards under Paul Draper pursued single-vineyard Cabernet and Zinfandel. UC Davis provided the scientific backbone, with researchers like Maynard Amerine and Albert Winkler developing the heat summation system that guided grape variety selection across California's diverse climates.

• Robert Mondavi founded his Oakville winery in 1966, pioneering premium varietal wines, French oak, and wine tourism in Napa Valley
• Warren Winiarski founded Stag's Leap Wine Cellars in 1970; his 1973 Cabernet would win the Judgment of Paris red wine category
• UC Davis researchers Amerine and Winkler developed the five-region heat summation classification, guiding grape variety selection statewide
• The 1960s to 1970s saw a wave of new premium wineries: Heitz, Freemark Abbey, Chateau Montelena, Diamond Creek, Caymus, and others

On May 24, 1976, British wine merchant Steven Spurrier organized a blind tasting in Paris pitting California wines against top French wines. Nine French judges scored the 1973 Chateau Montelena Chardonnay first among whites and the 1973 Stag's Leap Wine Cellars Cabernet Sauvignon first among reds, shocking the wine world. The event, later called the Judgment of Paris, proved California could produce world-class wine and triggered a global reassessment of New World winemaking. The decades that followed saw explosive growth: the Napa Valley AVA was established in 1981, cult Cabernets emerged in the 1990s (Screaming Eagle, Harlan Estate), and regions like Paso Robles, Santa Barbara, and Anderson Valley gained recognition. Today California has over 140 AVAs and more than 5,900 wineries.

• The 1976 Judgment of Paris saw California wines defeat top Bordeaux and Burgundy wines in both red and white categories
• The Napa Valley AVA was established in 1981 as one of California's first designated viticultural areas
• The 1990s cult wine era (Screaming Eagle, Harlan Estate, Bryant Family) pushed Napa Cabernet to global prestige pricing
• California now has over 140 AVAs and 5,900+ wineries, producing roughly 80% of all U.S. wine
