The region of Burgundy has become synonymous with high quality red wines, but in actual fact the region consistently produces a wide variety of fine wines of many different styles, rigorously protected by French wine laws designed to keep reputations and quality at a very high level. The region benefits greatly from a warm and sunny summer climate, which, coupled with the excellent quality soils which typify the region, and centuries of experience and expertise, has led to the region being known all over the world for the excellence of its produce. The majority of grapevines grown here are of the Pinot Noir varietal, which has helped Burgundy become known as the definitive region for elegant and smooth red wines, but Chardonnay grapes and many others are also grown in abundance and used to make both still and sparkling wines. 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.
