The Sonoma Coast American Viticultural Area (AVA) is one of California's largest and most diverse wine regions, stretching from San Pablo Bay to the Mendocino County border. Established in 1987, it encompasses approximately 500,000 acres and is known for its cool climate and high rainfall relative to other parts of Sonoma County. The region's proximity to the Pacific Ocean provides a unique terroir that is ideal for cool-climate grape varieties such as Pinot Noir and Chardonnay. The AVA includes several sub-regions, each with its own distinct characteristics. Notable wineries in the Sonoma Coast AVA include Sonoma Coast Vineyards, Peay Vineyards, and Flowers Vineyards & Winery .
