I went to wine country last June. I did a ton of research for both Sonoma and Napa. We went for four days and there was no way to cover everything, so we concentrated on Sonoma. But, I have the research on Napa and would be glad to share my research.
Good information and lots of coupons are available at

If you want to taste a lot of different wines without travelling to all of the vineyards, you can go to Napa Wine Merchants (1146 First St., Napa, 1-707-257-6796) and sample wines from over a dozen wineries.
The Nap Valley Wine Train offers luncheon & winery tours and dinner tours (1275 McKinstry St., Napa, 1-800-427-4124).
As far as tastings go, the wineries have no problem with sharing. My husband and I would split the tasting so that neither one of us would drink too much. There is also the option of spitting. Make sure you eat and just take your time and soak it all in.
Another place you may want to visit is the Jessel Gallery (1019 Atlas Peak Rd., Napa, 1-707-257-2350, hours 10:00 a.m. - 5:00 p.m.). This is a free gallery with great paintings and prints.
