One of California’s most notable AVAs, located in the southern part of Sonoma County. It has a varied terroir and warm climate that specializes in Cabernet Sauvignon, Zinfandel and Chardonnay. Sonoma Valley lies between the Mayacamas and Sonoma mountains and follows the Sonoma Creek for its entire length. It is influenced by its sheltered position between the hills as well as its proximity to San Pablo Bay to the south. The bay helps to moderate the normally-hot climate. Sonoma Valley’s southern, cooler area is also part of the Carneros AVA, which extends into neighbouring Napa Valley.
