Champagne is a sparkling wine produced from grapes grown in the Champagne region of France following rules that demand secondary fermentation of the wine in the bottle to create carbonation. Some use the term champagne as a generic term for sparkling wine, but many countries reserve the term exclusively for sparkling wines that come from Champagne and are produced under the rules of the appellation. The primary grapes used in the production of Champagne are Pinot noir, Chardonnay and Pinot Meunier. Champagne appellation law only allows grapes grown according to appellation rules in specifically designated plots within the appellation to be used in the production of Champagne. Some sparkling wines produced in other regions of the world use other grapes.
