We didn't visit any on this particular trip, but have enjoyed the many wineries in the area many times in the past. The reds af the area are particularly good. Perhaps it is because of the high iron content of the soils, but zinfandels, cabernets, barberas, syrahs and petite syrahs...wonerful in the area. Drytown winery in Drytown has a good Chardonney though (light on the oak... I don't like too much oak - so figure from there). Story, just out of Plymouth, also has a good Chardonney. Red wine all over is good. Montevina has wonderful barberas and syrahs. Check out the map at
