Fine living is on tap in this sumptuous backyard that's all about relaxing gatherings for friends and family. Jake and Joel pay homage to the upscale Napa Valley with a metal sculpted water feature with oversized steel grape leaves and wine bottle spouts, a granite-topped bar skinned in wine boxes flanked by a kegerator fashioned from a wine barrel, a gabled overhead shade structure and a wood-fired hot tub looking down on a cozy sunken seating area.
