Carneros is one of California's key wine producing regions, situated close to the Pacific coast. Although Carneros is relatively young, having been first used for viticulture in the 1940's, it has proven to be a highly successful region, capable of growing high quality grapes and producing wines of real character and distinction. Unlike many other regions of California, Carneros is considerably cooler, and benefits from the tempering effect of Pacific fog on the vineyards. As a direct result of this, Carneros wineries are able to produce fine grape varietals which require cooler temperatures, such as Chardonnay and Pinot Noir – grapes perfect for the sparkling wines the region has become famous for. However, plenty of still red and white wines are made in the region, from a wide array of grape varietals.
