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. Situated in the north-western part of Italy, the region of Piedmont is known worldwide and is highly respected for the quality of the wines produced there. Many of the most successful sub-regions in Piedmont produce many of the world's finest red wines, such as those made from the excellent Nebbiolo grape varietal in areas such as Barolo and Barbaresco. However, the historic wineries which typify this region use a relatively wide variety of grapes, including Dolcetto and Barbera for their red wines, which are typically aged and have a delightful velvety character. Piedmont isn't all about beautifully complex red wines, though, as it is also famed for high quality, elegant sparkling wines, notably the Asti wines made with the white Moscato grape. The region benefits from a range of terroirs which are often well expressed in the sparkling wines, and a wonderfully consistent climate ideal for vineyard cultivation.
