Beyond the stunning winery design by San Francisco-based Walker Warner Architects the draw here is simple: It's an opportunity to taste from the winery's annual 8,000 cases of one very good and well-known red wine made from a blend of the vineyard's best cabernet sauvignon, merlot, and cabernet franc. Along the way you'll learn a little background in biodynamic farming, a growing technique that takes sustainable farming a step further by basing its practices on the moon's cycles and creating a naturally symbiotic growing environment (hence the property's cows and chickens, which are believed to "calm the vines" and perhaps the crooning of Ugo, Quintessa's oldest employee, who warbles to the wine in the underground barrel caves). It may seem a bit hippie-dippy, but the $45 private tour and tasting with food pairings may just turn you into a believer. If you want to take a potable memento for the road, note that a bottle of wine costs $145.
