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. The Rhone Valley of southern France is a particularly fascinating wine region, with a history that stretches back to at least six hundred BCE, when the ancient Greeks first began cultivating vines there. The region itself is split into two distinct sub-regions, with the northern sub-region being famed for its production of exceptional Syrah, Marsanne, Roussane and Viognier wines, packed full of interesting character and expressing the terroir found there. The southern sub-region is home to an enormous variety of grapes, and produces red, white and rosé wines, and some of the world's most famous and adored blended wines. The continental climate of the region is ideal for growing grapes, and the winds which blow from the Central Massif help temper the heat in the vineyards, leading to very ripe fruits holding plenty of flavor.
