I want to plan a wine tasting day trip for a us and another couple (we're in OC). Does anyone have any suggestions for wineries to visit? We aren't aficionados by any means, but would like to learn more about wine. I'm thinking at most 3-4 wineries. Also, I wanted to bring a picnic lunch with us. What wineries have picnic grounds/allow you to bring your own food if you taste there? Thanks for the help.
