Visitors interested in intimate, comprehensive tours and a knockout tasting should schedule a tour at this winery founded in 1973 by major wine world player Joseph Phelps. A favorite stop for serious wine lovers, primarily due to their ever-popular and expensive Insignia wine, this modern, state-of-the-art winery and big-city vibe are proof that Phelps's annual 80,000 cases prove fruitful in more ways than one. While at first meeting it seems seriousness hangs heavier than harvest grapes, the mood lightens during the hour-plus $25 informal tasting or any of the $40 "seminars" (think blending or wine appreciation), which include tastings of five or six wines. The three excellently located picnic tables, on the terrace overlooking the valley, are available on a first-come, first-served basis, with preference given to Phelps wine club members (join and get wine shipped a certain number of times per year) who are also able to make a reservation.
