Sugarloaf Mountain West

Napa Valley

Cabernet Sauvignon, Cabernet Franc, Merlot

Suscol VineyardSugarloaf Mountain West offers a unique terroir for Bordeaux varietals in the Napa Valley. Unlike warmer vineyards up-valley, the climate of Suscol Bench naturally provides a longer hang-time resulting in profound color and flavor intensity. Combined with a southwestern exposure and a rock-laden soil harvesting the sun’s energy, this extraordinary terroir delivers the exceptional ripeness necessary for both the power and complexity required of great Cabernet-based wines.

WINES FROM SMW: Indigo color; concentrated black-fruit and cedar aromas that carry through with a burst of flavor on the palate; full-bodied and powerful in the mouth with a mild astringency in the lingering finish.
