I've toured the California wine country a number of times, and a visit always affords many fine tasting opportunities. Visiting the wineries provides a great cultural and historical view of this part of California as well. In Napa, I've been greeted by the owner as I drove up to the lovely Wermuth winery over on the Silverado Trail, and taken tours of the Mondovi and Beringer wineries. These wineries are known for their wines as well as their architecture. One of my favorite visits to the Sonoma wine country began with a lovely bed and breakfast and ended with a peaceful coastal drive on Highway 1. In between, we completed quite an interesting tour of the wineries of Sonoma. The home of Korbel Champagne was rich with history and lovely architecture. Other places we visited included the cave of Field Stone, former hop storage containers at Hop Kiln, and a beautiful mill at Mill Creek. The diversity of wineries in Sonoma is part of the charm.
