Plumpjack is a boutique winery nestled in the Oakville vineyards. You will love the view of the vineyards as you turn off the Silverado Trail onto Oakville Crossroad. This is the same company that runs the famous Plumpjack Restaurants located in San Francisco and Squaw Valley, Lake Tahoe. Since the wine production is small, the wines are sold mainly at the winery and to high-end restaurants. Their best wines are the Cabernets. Tasting room open daily 10 am to 4 daily, (707) 948-1220
