The sparkling wines of Champagne have been revered by wine drinkers for hundreds of years, and even today they maintain their reputation for excellence of flavor and character, and are consistently associated with quality, decadence, and a cause for celebration. Their unique characteristics are partly due to the careful blending of a small number of selected grape varietals, most commonly Chardonnay and Pinot Noir. These grapes, blended in fairly equal quantities, give the wines of Champagne their wonderful flavors and aromas, with the Pinot Noir offering length and backbone, and the Chardonnay varietal giving its acidity and dry, biscuity nature. It isn't unusual to sometimes see Champagne labeled as 'blanc de blanc', meaning it is made using only Chardonnay varietal grapes, or 'blanc de noir', which is made solely with Pinot Noir. 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.
