We invite you to visit our quaint tasting room located in the heart of downtown Sonoma, steps away from fine dining, shopping and the historic Sonoma plaza. A short 45 minutes drive from San Francisco, Castle’s warm, full-service tasting room is a reflection of the same quality we put into every bottle of wine. For a small fee, guests are invited to enjoy a tasting of one of several special wines with our knowledgeable staff in a friendly, educational and warm environment.
