The beautiful region of Hawkes Bay in northern New Zealand is home to many of the country's oldest wineries, and is the birthplace of New Zealand's now enormous and important wine industry. Since the 1850s, Hawkes Bay has proven to be one of the country's most successful and widely renowned wine regions, with turnover increasing each year, and with its excellent quality, characterful and flavorful wines finding new fans all the time. The region is widely regarded as being the sunniest in New Zealand, and has a fantastic climate for viticulture. Indeed, the moderate humidity, low rainfall and blazing sunshine help the grapes which grow there flourish to full ripeness, and allow the resulting wine to be packed full of flavor and the finest features of the terroir. 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.
