Russian River Valley
The Russian River Valley AVA is an American Viticultural Area (AVA) in Sonoma County, California. Centered on the Russian River, the Russian River Valley AVA accounts for about one-sixth of the total planted vineyard acreage in Sonoma County. The appellation was granted AVA status in 1983 and enlarged in 2005. The area generally lies between Sebastopol and Santa Rosa in the south, and Forestville and Healdsburg in the north.
The Russian River Valley has a characteristically cool climate, heavily affected by fog generated by the valley's proximity to the Pacific Ocean. The area is known for its success with cool climate varietals, notably Pinot Noir and Chardonnay.
