With a wide range of climate and soils reflected in its 13 AVAs (as of 2012), Sonoma County could almost be considered a whole wine country within itself. It is one of the largest wine regions and significantly overshadows Napa in terms of quantity produced. The main AVAs include: Alexander Valley and Dry Creek, known for good Sauvignon Blanc and Zinfandel; Knights Valley and Sonoma Mountain, for its Cabernet Sauvignon; and Russian River Valley, Sonoma Coast, Sonoma Mountain, for their Chardonnay and Pinot Noir.
