Monterey AVA

Monterey is an American Viticultural Area (AVA) located in eastern Monterey County, California. It was recognized on July 16, 1984 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by the Monterey Winegrowers Council to establish the "Monterey" viticultural area. The designated area within the multi-county Central Coast AVA expands almost the entire length of the county from the Monterey Bay southern shoreline to the Salinas river valley framed by the Santa Lucia, Sierra de Salinas and Gabilan Ranges stretching north-south for about 100 miles (160 km) from Watsonville to its southern point, abutting the town of Paso Robles in San Luis Obispo County. Monterey AVA expands approximately 360,000 acres (560 sq mi) with about 40,000 acres (16,000 ha) of cultivated vineyards. The AVA includes parts of the Carmel and the Salinas valleys containing five smaller American viticultural areas: Arroyo Seco, Hames Valley, San Bernabe, San Lucas and Santa Lucia Highlands. The northern portion is a cool growing region with a very long growing season. Daytime temperatures rarely exceed 75 °F (24 °C) in most parts of the region, although the southern segments of the AVA can measure 100 °F (38 °C) at times. The soil is sandy loam and most regions require irrigation from the Salinas River.

As the largest AVA in Monterey County, the region is home to considerable variations in microclimates and soil types with the dominant soil being loam based. In areas closer to the cold Pacific currents, Pinot Noir, Riesling and are the predominant varieties, while in the warmer inland valleys further south, Bordeaux varietals are most often grown. Approximately 50 percent of the vines in production are Chardonnay.
