Champagne is a French sparkling wine. It is named after the Champagne wine region in Grand Est. This is a region in France with many vineyards that grow grapes and make wine. Note that this region is not identical to the French region of Champagne-Ardenne, nor the historical province Champagne. Champagne contains carbon dioxide. One of the features of Champagne wine is that this carbon dioxide originates from a second fermentation in the bottle, and is not added.
