Monterey AVA is in Monterey County, south of San Francisco. The long, narrow appellation is a 100-mile ribbon of land that extends from north Monterey County south to the edge of Paso Robles. Most of the AVA is considerably inland from the Pacific Coast, and to the east of the Santa Lucia mountain range. About 40,000 vineyard acres are inside the AVA, making it one of California’s larger appellations. Monterey County, in fact, produces almost as much wine as Napa County because the floor of the valley is taken up by large industrial vineyards producing grapes for bulk wine. However, there are also many premier wine estates within Monterey AVA and its numerous sub-appellations. Monterey AVA includes four recognized micro climates, ranging from a cool, maritime climate at the north end to what is known in California as a Region 4 climate in the south, meaning relatively hot and dry. Monterey AVA includes parts of Carmel Valley and Salinas Valley. More than 50% of the grapes grown in the Monterey AVA are Chardonnay, though the many terroirs and micro climates mean that numerous grapes grow well. Merlot, Pinot Noir, Riesling, Sauvignon Blanc, Chenin Blanc, Zinfandel and Pinot Blanc are widely planted.
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.
