Santa Maria Valley AVA

Santa Maria Valley is an American Viticultural Area located in Northern Santa Barbara County and San Luis Obispo County, California USA.

The Santa Maria Valley is a natural funnel-shaped valley opening west to the Pacific Ocean. The elevation of the area ranges from approximately 200 feet (60 m) at the intersection of Highway 101 and Santa Maria River to approximately 3,200 feet (980 m) at Tepusquet Peak. The grapes that are grown within the area are on the valley floor at an approximate elevation of 300 feet (90 m) and on the slopes and rolling hillsides up to an elevation of 800 feet (240 m). The soils within the area range in texture from a sandy loam to clay loam and are free from adverse salts..

Climate

Since the valley opens to the ocean, there is no opposition to the sea fog that moves in overnight, engulfing lower lying vineyards, and often lingering into mid-day. This creates a cool growing environment that is a Region I on the Winkler Scale. The valley features a long growing season and very little rainfall, meaning grapes have extensive time to build flavor on the vine.

This appellation is the oldest in this portion of California.. Grape growing in this region dates back to the Mexican Colonial period of the 1830s . In the late 1960's commercial vineyards were planted to supply wineries around the state. Since then, vineyards in the valley have come to encompass 7,500 acres (3,000 ha)

The Santa Maria Valley AVA is home to many well-regarded vineyards, including Riverbench, Addamo, Rancho Sisquoc, Au Bon Climat, Lucas & Lewellen, Io, Foxen, Cottonwood Canyon, Costa De Oro, Byron, and Cambria.

Owing the cool growing climate, the valley is best known for its Pinot Noir, Syrah, Chardonnay, and Pinot Blanc.

On January 28, 2011, the southern border of the Santa Maria Valley AVA was adjusted to bring it into closer alignment with the physical watershed boundary of the Santa Maria River. The revised boundary approximately follows the ridge line dividing the Santa Maria Valley from the Los Alamos Valley. This change added 18,790 acres and nine vineyards to the area.
