Sparkling wine is a wine with significant levels of carbon dioxide in it making it fizzy. The carbon dioxide may result from natural fermentation, either in a bottle, as with the méthode champenoise, in a large tank designed to withstand the pressures involved (as in the Charmat process), or as a result of carbon dioxide injection. Sparkling wine is usually white or rosé but there are many examples of red sparkling wines such as Italian Brachetto and Australian sparkling Shiraz.
