Santa Cruz Mountains AVA includes high elevation territory in the counties of Santa Clara, Santa Cruz and San Mateo. The AVA follows the coast line from San Francisco to Monterey with elevations from 400 feet to 3,000 feet above sea level. There are 1,500 vineyard acres and the AVA was established in 1981. Despite the challenging terrain in these rugged mountains and hills, highly esteemed wineries have been located here since the early 20th century, when Paul Masson, a Frenchman by birth, started making sparkling wine in the area. By the 1970s vineyards were growing Cabernet Sauvignon, Chardonnay and Pinot Noir. Numerous microclimates within the AVA offer viticulturists diverse growing conditions, and many varietals are grown successfully.
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.
