Wente Vineyards is the oldest continuously operating, family-owned winery in the United States. It was established by Carl Wente in 1883 on 47 acres of land. Having received training in wines while working for Charles Krug of Napa Valley, Wente purchased a few vineyards and land of excellent soil. In 1935 his sons, Ernest and Herman, introduced California's first varietal wine label, Sauvignon Blanc.
