The country’s most famous wine producing region, Napa Valley stretches from the North bay of San Francisco Bay in the South, all the way up to Mount Saint Helena in the North. Although the climate is suitable for a wide range of varieties, Cabernet Sauvignon is dominant and practically synonymous with the region. To account for its geographical diversity, the valley is split up into a number of AVAs. From north to south, the valley consists of Calistoga, St. Helena, Rutherford, Oakville, Yountville, and Oak Knoll. Higher elevation sites include Howell Mountain on the east and Mount Veeder on the west. On its own, Stags Leap District is tucked into the very south east corner of the valley.
