Santa Barbara County has a range of climates within its three American Viticulture Areas (AVAs). Soils in the vast region include ancient beach and diatomaceous earth to chirt and limestone. The three growing regions range from cool coastal areas to warm inland valleys.
Santa Ynez Valley is the area’s largest AVA region and has the highest concentration of wineries. Santa Ynez Valley is a long, east-west corridor with very cool temperatures on the coast that become progressively warmer inland. There are approximately 2,200 acres under vine planted to Chardonnay, Sauvignon Blanc, Viognier, Cabernet Sauvignon, Pinot Noir, Syrah, and Merlot.
The Sta. Rita Hills AVA is located between the towns of Buellton and Lompoc and includes about 1700 planted acres within its small 10 square mile area. Its vineyards are cooled by marine winds and coastal fog. Pinot Noir dominates the small appellation and shares vineyard space with Chardonnay and Syrah. Because of a legal issue with the Chilean winery, Vina Santa Rita, the official AVA designation is a bit different than the actual Santa Rita Hills name.
Santa Maria Valley AVA has the largest amount of grapes planted with about 7,500 acres. Yet only a dozen or so wineries are located here. Large tracks of historic and prestigious vineyards benefit from the fog and coastal breezes and contribute to an extended growing season. Chardonnay and Pinot Noir lead the region in vineyard acreage, with
Cabernet Sauvignon, Cabernet Franc, Grenache, Merlot, Mourvedre, Sangiovese and Syrah also being grown.
