Hit 26 wineries in 3 days. We go for the wine, and usually don't do any tours. Here are my favorite wineries, and a couple that were not so good.
Artesa - This place is advertised everywhere, so we figured we had to go and see what the buzz was about. I have to admit, it is a beautiful location. However, we were not impressed at all with the wines.
Frog's Leap - This is the one place we went where we had to make an appointment, and we are glad we did. This turned out to be so much fun. The tour guide, Emily, had great energy. Our wine glasses stayed full during the entire hour, it was very casual, and Emily told us all about the history of how the winery got started. Great story, BTW. So, not only did we enjoy the tour, the wines were fantastic.
Carnereos Creek (being renamed to Mahoney) - Great overall tasting. Down the hill from Artesa.
Sterling - By far, the best wines are here. Every wine I tried made my knees weak. This winery is beautiful, and like I said, these wines are my favorite in the valley.
Clos Pegas - Have heard lots of people talk about this place. They have super dry red wines. If you like tannic wine, this is the place to go. Personally, I don't like really dry wines, but, everyone is different.
V.Sattui - Everyone has to go here for the picinic food, and the wine. We just love their Gamay Rouge. This trip, we made sure we got 4 bottles of it, instead of 1 bottle like we did last time. Besides, the tasting is free, and you can pick up a shipping box for only $5! Cheapest price we have found.
Frank Family - One of the most fun tastings around. The guys over at this place are great. The wine rocks too....
Other wineries that had good overall tastings: Luna, Grgich Hills, Domaine Chandon, St.Suprey, Peju, Cuvaison.
While we were there, we noticed that some folks bring their young kids. How boring for them! Napa is a place for adults, not children. Parents, take your kids to Disneyland, not Napa Valley. I'm sure there are people who will read this and get offended because they have taken their kids to Napa before, or are planning on taking them. I apologize to these people, but I think I speak the truth. Most people go to Napa for romance. They don't go to have screaming kids running around them as they sip wine in the beautiful valley.
