As with nearby Australia, New Zealand has over the past century proven itself to be a superb location for producing high quality wines in vast amounts, with much of the cooler regions of both islands being used primarily for vine cultivation. New Zealand wineries are notable for their enthusiasm in regards to experimentation, and for utilizing modern technologies and methods to make the most of the imported grape varietals which flourish in the rich, fertile soils and oceanic climate. In recent years, it has been the New Zealand Sauvignon Blanc wines which have gained the most attention, as a result of their smoky character and ability to carry the mineral rich nature of the terroir they grow in. Changing consumer interests have brought about a considerable rise in the production of organic and sustainable wines in New Zealand, of which again, the Sauvignon Blanc varietals are leading the way in regards to excellence, flavor and overall character. Riesling grapes have been grown in and around central Europe for centuries, and over time, they became the lasting symbol of south Germany's ancient and proud wine culture. Whilst the reputation of German wines abroad has in the past been mixed, the Germans themselves take an enormous amount of pride in their wineries, and Riesling grapes have now spread around the globe, growing anywhere with the correct climate in which they can thrive. Riesling grape varietals generally require much cooler climatic conditions than many other white grapes, and they are generally considered to be a very 'terroir expressive' varietal, meaning that the features and characteristics of the terroir they are grown on comes across in the flavors and aromas in the bottle. It is this important feature which has allowed Riesling wines to be elevated into the category of 'fine' white wines, as the features of the top quality bottles are generally considered to be highly unique and offer much to interest wine enthusiasts.
