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. Of all the New World wine countries, perhaps the one which has demonstrated the most flair for producing high quality wines - using a combination of traditional and forward-thinking contemporary methods - has been the United States of America. For the past couple of centuries, the United States has set about transforming much of its suitable land into vast vineyards, capable of supporting a wide variety of world-class grape varietals which thrive on both the Atlantic and the Pacific coastlines. Of course, we immediately think of sun-drenched California in regards to American wines, with its enormous vineyards responsible for the New World's finest examples of Cabernet Sauvignon and Merlot based wines, but many other states have taken to viticulture in a big way, with impressive results. Oregon, Washington State and New York have all developed sophisticated and technologically advanced wine cultures of their own, and the output of U.S wineries is increasing each year as more and more people are converted to their produce.
