Sparkling wine is any type of wine that contains bubbles from carbon dioxide. Carbonation is achieved either by injection or as a result of natural fermentation in the bottle or a large tank. Champagne is the most common kind of sparkling wine, but it’s incorrect to call all sparkling wine "Champagne." Sparkling wines are made all over the world and labeled according to the region and methods used to produce a bottle. Some examples of other sparkling wines include Espumante from Portugal, Cava from Spain, Spumante from Italy, and Sekt from Germany and Austria.
