Napa's larger, cooler, more diverse neighbour, Sonoma runs from the fog- chilled Pacific to warm inland valleys, packing an extraordinary range of climates and grapes into one county. Cool Russian River and Sonoma Coast make some of California's finest Pinot Noir and Chardonnay; warmer Dry Creek and Alexander Valley grow Zinfandel and Cabernet.
Less glossy and more agricultural than Napa, Sonoma has quietly become California's most exciting county for cool-climate wine, with a deep bench of old-vine Zinfandel and field blends alongside its Burgundian varieties. It is the Golden State's other great wine country — and, to many, its more soulful one.
