The grapes for this exceptional Cabernet Sauvignon come from three of Napa Valley’s finest hillside vineyards - our Oso Vineyard in Pope Valley, Suscol Ranch in southern Napa, and Atlas Peak vineyards - which boast well-drained volcanic soils and excellent sun exposures. Tony Coltrin believes these conditions, which foster vines with modest canopies and small crops of intensely flavored grapes, produce the very best Napa Valley Cabernet Sauvignons.
