The hunt for California's greatest terroirs has put a lot of mileage on our cars. It's necessitated before-sunrise journeys to places out of cell phone range. Many of these wild places, beautiful as they may be, don't make the cut. Only a handful do. We began drawing our own map of Golden State Grand Crus in 2005, and have bottled wine from nineteen American Viticultural Areas. Today the focus is on our home county of Sonoma, Mendocino, and Santa Cruz...with some outliers in Clarksburg and Santa Barbara.
