"Without question, Quintessa is one of our favorite wine tasting experiences in the valley—it's also one of the locations where we recommend springing for a tour. The grounds are truly breathtaking (they include a calm, clear lake surrounded by vines), and you'll finish up at a perfect hilltop perch, taking in a grand view of the valley while you sip on one of Quintessa's red blends.
