Rombauer Vineyards was founded in 1982 by Koerner and Joan Rombauer and sits on a tree covered knoll overlooking the Napa Valley. The winery features caves that extend for over a mile into the hillside. The caves provide a constant temperature and humidity which result in optimum conditions for aging our wines. Rombauer Vineyards emphasis on the joy of wine comes from the heritage of the Rombauer family. Koerner’s ancestors made wine in the famous Rheingau region of Germany. Every family member is actively involved in the day to day operations of the winery.
