California’s Napa Valley is the most famous and prestigious wine-growing region in the United States. Napa Valley is the name of the AVA, or American Viticultural Area, within Napa County. It was established in 1981 and covers over 225,000 acres of land. It is about 30 miles long and five miles wide, located approximately 35 miles north of San Francisco, with the Mayacamas Mountains to the west and the Vaca Mountains to the east. It is home to 45,000 acres of planted vineyards, over 400 wineries, and 815 wine brands.
Napa Valley enjoys a long growing season with a dry Mediterranean climate characterized by warm sunny days and cooler evenings. Despite its relatively small size, Napa Valley boasts a range of various microclimates, soil types, elevations, and weather patterns within the region. These variances affect the quality and taste of the resulting wine produced. Because of this, winemakers take advantage of these distinctions in climate, geology, and weather by planting grapes in the regions that are most suited for that particular varietal. These specific sub-regions have their own boundaries and are actually designated as their own unique appellations. There are 15 appellations, or particular wine-growing regions defined by their own unique climates and soils, recognized within Napa Valley.
Quality wine has been produced in Napa since the 1960s, but it was the 1976 Judgment of Paris that put Napa on the map as one of the world’s premier wine-producing regions. The Judgment of Paris was a blind wine-tasting held in Paris with a panel comprised of highly regarded French wine experts. Napa Valley red and white wines beat out its French rivals and solidified Napa Valley’s status as a world-class wine producer.
While a number of varietals thrive in the region, Cabernet Sauvignon has become the grape most associated with Napa Valley. It is widely planted across the region with a total of 18,200 acres. For white wine varietals, Chardonnay is the most popular in the region with over 7,300 acres. Other prominent varietals grown in the region include Merlot, Sauvignon Blanc, Pinot Noir, and Zinfandel.
