Sonoma County is Napa's larger, more diverse neighbour — often compared to Burgundy (multiple distinct terroirs and varieties) versus Napa's Bordeaux (one dominant variety, one dominant style). The Russian River Valley produces California's benchmark Pinot Noir and Chardonnay — the Goldridge sandy loam and the persistent morning fog from the Pacific create an extended growing season that produces wines of elegance rarely achieved elsewhere in California. Dry Creek Valley's old-vine Zinfandel (some vines 120+ years old) is a unique American wine identity. The Sonoma Coast's extended boundaries were contested but now produce the state's most exciting cool-climate expressions.
