As the world's fifth largest producer of wine, after France, Italy, Spain and the United States, Argentina has plenty to offer the international wine market in regards to both quantity and quality. Despite this being the case for several decades now, it has only been since the end of the twentieth century that the Argentinian wine industry has really begun to up their game when it comes to the methods and techniques required to produce world class wines, which are both representative of their country and region of origin, and which stand alone as complex, interesting and delicious wines to drink. As Argentina became a serious contender in the international wine market, wineries previously concerned primarily with high volumes began to change their priorities, and formerly struggling small bodegas and independent wineries began to find success. Nowadays, well crafted wines from smaller vineyards in Argentina are being lauded as some of the finest in the world, and the country is starting to reap the benefits of its heritage, which include some very old vines, and up to four centuries of experience in wine production. 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.
