Since 1976, Kenwood Vineyards has been the exclusive producer of wines from the historic single vineyards of the famous Jack London Ranch. Located on the eastern slopes of Sonoma Mountain, the Jack London Vineyard gets early morning sun followed by breezes in the afternoons that temper the day’s most extreme heat. The red volcanic soil and warm climate of this hillside vineyard combine to produce full-bodied Cabernet Sauvignon, Merlot, Syrah and Zinfandel with intense varietal flavors.
