Tom,
If you ever get the opportunity to tour the Ravenswood winery in Sonoma, it is well worth it! My wife and I stayed at a resort in Sonoma on our honeymoon two years ago and visited the winery. While sampling various wines we met the original owner of the winery and he gave us a fabulous bottle (Zinfandel) as a gift. We told him we were on our honeymoon.
Cheers,
Shaun
