We just went to Napa last weekend and visited Smith Madrone. It was awesome. They were only pouring two wines, the Chardonnay and the Cabernet and they were both excellent. They also gave us a taste of the Riesling that hadn't been bottled yet, also tasty. What was better was that Charles spent two hours with us. We talked about growing grapes and making the wine, of course. We also talked about history of Napa, Bottle Shock, science, history of science, psychology of pricing, etc. This is a man that loves what he does and it shows. It was a ton of fun and very interesting. I can't recommend this place enough. I'll be back. Another place we really enjoyed at the other end of the valley was Silenus. This isn't a winery per-se but rather a collective of very vintners. They had a tremendous variety of wines from a dozen different vintners all made in that facility. It was really interesting to see how different all the wines were. Jim was pouring the wine and was extremely knowledgeable and helpful. We found several that we really liked.
