I drank a Cherry Block from Sebastiani last night, great wines from Sonoma. You will love Napa, you have to see Copola's winery just for the sheer beauty of the place. As Peter said too many good ones for one visit. If you have enough time you will want to see Napa and Sonoma. Napa is to wine ,what Pebble Beach is to golf.

A computer once beat me at chess, but it was no match for me at kick boxing.
