A Rich History Of Wine
Wine has been a part of the Bay Area’s history for centuries. Spanish missionaries planted the first vines here in the late 18th century, but the modern era of winemaking took off in the mid-1800s.
By the mid-19th century, regions like Livermore Valley and Santa Clara Valley produced award-winning wines, helping establish California as a serious wine region. Today, many winemakers continue to build on that heritage, crafting wines that reflect the region’s unique terroir. In the 1980s, a new wave of urban winemakers, led by pioneers like Edmunds St. John, started crafting high-quality wines in city settings, using grapes from surrounding regions.
Defining The San Francisco Bay AVA
The San Francisco Bay AVA, established in 1999, is a federally designated American Viticultural Area (AVA) encompassing nearly 1.5 million acres surrounding the Bay Area, of which 1,700 are dedicated to vineyards. Carolyn Wente, President of Wente Vineyards, was a driving force behind the creation of this AVA.
The AVA includes Alameda, Contra Costa, San Francisco, San Mateo and Santa Clara counties, and parts of San Benito, Santa Cruz and Solano counties. It includes six recognized sub-AVAs: Contra Costa, Lamorinda, Livermore Valley, Pacheco Pass, San Ysidro District and Santa Clara Valley. By the way, it doesn’t include the Santa Cruz Mountains AVA, which stands alone.
What Makes Growing Wine in the San Francisco Bay Area Great
The San Francisco Bay AVA’s diverse microclimates and soils mean there is no single “Bay Area wine style,” but the region’s wines are linked geographically. This corner of California has the classic warm summers of a Mediterranean climate, but the uniting factor of the wines is the cooling influence of San Francisco Bay.
Coastal breezes and morning fog moderate temperatures, creating ideal conditions for growing Chardonnay and Pinot Noir in cooler areas. Meanwhile, warmer inland spots like Livermore Valley and Contra Costa County are perfect for robust reds like Cabernet Sauvignon, Zinfandel and Petite Sirah.
