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. As historically one of the most important regions in the world regarding trade and experimentation, it comes as no surprise to discover that Veneto has always been a well respected and innovative wine region. This area of north-easterly area of Italy benefits greatly from a continental climate tempered by the Alps, and plenty of influence from the Germanic countries it is near to. Veneto is most commonly associated with beautifully elegant white wines, such as those of Soave, and has over ninety thousand hectares under vine. Impressively, within that area, over a third of the vineyards in the Veneto region have been granted official AOC status, and many of the sub-regions and appellations of Veneto have gone on to be world-famous in regards to quality. One such example is Valpolicella, where some of Italy's finest and most complex red wines are produced.
