Boy, this is open to a lot of opinion... IMHO, you gotta go North, at least to the Santa Ynez Valley just over the Santa Ynez Mountains. There lie some 18,000 acres of hilly terrain that's home to almost 50 wineries... With a winemaking history that stretches back to the late 18th Century, the region produces more than a million cases of wine a year, and is best known for its Chardonnays and Syrahs, as well as Sauvignon Blancs. A nice meandering couple hour's drive North of Santa Barbara will get you to the area. Of course, a full day's drive will deliver you to the Napa Valley and some really great wineries!
