The region of Burgundy has become synonymous with high quality red wines, but in actual fact the region consistently produces a wide variety of fine wines of many different styles, rigorously protected by French wine laws designed to keep reputations and quality at a very high level. The region benefits greatly from a warm and sunny summer climate, which, coupled with the excellent quality soils which typify the region, and centuries of experience and expertise, has led to the region being known all over the world for the excellence of its produce. The majority of grapevines grown here are of the Pinot Noir varietal, which has helped Burgundy become known as the definitive region for elegant and smooth red wines, but Chardonnay grapes and many others are also grown in abundance and used to make both still and sparkling wines. The green skinned grapes of the Sauvignon Blanc varietal had their origins in Southern France, where they are still widely grown and used for many of the excellent young and aged white wines the region is famous for. Today, however, they are grown in almost every wine producing country in the world, and are widely revered for their fresh and grassy flavors, full of tropical notes and refreshing, zesty character. Sauvignon Blanc grapes thrive best in moderate climates, and ripen relatively early in the year. This has made them a favorite for many wineries in the New World, where they can still produce healthy and high yields in the earlier part of the summer before the temperatures become too hot. Too much heat has a massively adverse effect on Sauvignon Blanc, as the grapes become dull in their flavor, and the wine produced from them loses all its unique character and high points. As such, Sauvignon Blanc farmers have had a lot of trouble from global warming and climate change, as they are being forced to harvest their crops increasingly earlier in the year when it is cool enough to do so.
