Atlas Peak AVA is perched above the Stags Leap AVA to the northeast of the city of Napa. Elevation ranges from 760 to 2,600 feet, and temperatures are up to 15 degrees cooler in the Atlas Peak vineyards compared with vineyards in the valley. There are 1,500 vineyard acres planted primarily to Cabernet Sauvignon and Chardonnay. The appellation was named for Atlas Peak, which, at 2,633 feet above sea level, is the highest peak in the area.
Despite its popularity, this grape is quite rare. Less than 10,000 acres are planted worldwide, with the bulk in California. In France, the grape is referred to as Durif. Not to be confused with Syrah, Petite Sirah is a cross of Syrah and Peloursin. The result is darker and fuller.
