Napa Valley, an hour’s drive north of San Francisco, California, is the most famous and prestigious wine region anywhere in the New World. Although a number of grape varieties are grown in the valley’s vineyards, the area is particularly known for its Cabernet Sauvignon. The classic “Napa Cab”, the archetypal Napa Valley wine, is a rich, oak-aged red with aromas of blackcurrant, boysenberry, liquorice, vanilla and smoky, bittersweet chocolate.
