Joseph Phelps is a premier Napa tasting room while keeping it relatively casual. You still need an appointment to get in, but after that, you're not kept on a schedule or rushed by any means.Phelps has a great variety of reds, of which the Insignia is the best you can taste at the winery, which goes for about $200-250 depending on the vintage. (They also have a red called Backus that is not available for tasting.) The Insignia is some of the best reds I've ever had. I also really enjoyed their Syrah and Pinot Noirs.
