A sparkling wine named for the old French province that serves as its origin, champagne is a classic drink often consumed at celebratory events. According to legend, the beverage was developed by a seventeenth century monk, Dom Pérignon, and is traditionally made from a blend of pinot and chardonnay grapes. Though true champagne is only produced in France, the term is often utilized in the United States and various other countries to describe a range of effervescent white and rosé wines. The effervescence of champagnes is a consequence of carbonic acid retained in the bottle after the final fermentation process and their relative sweetness is determined by the amount of cane sugar dissolved in the wine, extra dry and brut varieties containing the least amount of sweetener.
