Sonoma County, located west of Napa Valley and stretching to the Pacific Ocean, is a large and diverse wine region in California. With a history of winemaking dating back to the 19th century, Sonoma's varied terroir allows it to grow grapes in multiple places throughout the region. Bordered by the Mayacamas Mountains on the east and the Pacific Ocean on the west, the county encompasses a range of climates and soils. The Russian River Valley, known for its cool climate influenced by fog, is acclaimed for Pinot Noir and Chardonnay. Alexander Valley, further inland and warmer, excels with Cabernet Sauvignon. The Sonoma Coast, a region directly influenced by the Pacific's cool breezes and fog, is gaining recognition for elegant, cool-climate wines, particularly Pinot Noir and Chardonnay. This diverse landscape provides the fruit for an array of styles.
