Hartwell Estate Vineyards is on the Silverado Trail in the Stag’s Leap District. It was established in 1986 by Bob and Blanca Hartwell, who used the 20-acre property to raise cattle before slowing turning to winemaking. They had their first grape harvest in 1990 and for nearly a decade the wine was made and marketed by Grace Family Vineyard. In 1997 Hartwell built a winery and today the winemaker is Benoit Touquette, whose previous experience was at several Bordeaux chateaux. The estate makes Cabernet Sauvignon, Merlot and Sauvignon Blanc.
