Sparkling wine or sparkling wine, also popularly called bubble wine, is wine in which carbon dioxide is contained. The foam of the champagne and cava is obtained by a second fermentation in the closed bottle, so that CO2 cannot escape and is integrated into the wine. This is the so-called champenoise method invented by the French. Cava is also produced according to the same system.
In the second fermentation, large, closed tanks are used in some cases. Gasified wines are very different, to which artificial gas is added and should not be confused with sparkling wines. In this article we will talk about champagne – which can only be French, from the Champagne region and Spanish cava.
