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.
America's favorite red wine passion, Merlot is known for its role, sometimes as the primary varietal, in the great wines of Bordeaux. It is, by nature, an earlier maturing grape than Cabernet Sauvignon, and tends to have rounder, plummier, more forward fruit with lower tannins so it is often used to soften and round out the edges of the more astringent Cabernet. It is the grape of choice in Pomerol and St. Emilion, and represents the basis for some of America's most popular red wines, particularly from Washington, Napa Valley, Sonoma Country, the Central Coast, Long Island, Texas, and yes, Colorado.
