There are few wine regions in the world with a reputation as glowing and well established as that of the Bordeaux, in France. Situated mainly around the Dordogne and Gironde rivers, Bordeaux makes the most of its humid climate and rich, clay and gravel based soils to grow some of the finest examples of red and white grape varietals on earth. Wineries in this region have been in operation for hundreds of years, and have carefully developed the expertise required for the production of carefully balanced and utterly delicious blended red and white wines, alongside some exceptional single variety bottles. Many of the chateaux found in Bordeaux have become household names, due to their prestige and the excellence of their products, grown with love and dedication by heritage wineries in this beautiful and special region. 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.
