How does champagne get its bubbles?

The bubbles in champagne are triggered by the release of co2 gas. This gas is produced throughout the fermentation process, where yeast breaks down the sugars in the grape juice and converts them into alcohol.

AsHowToMakeWinecontinues, the carbon dioxide gas is produced in increasing amounts and eventually starts to leave from the champagne. This is why champagne requires to be kept in an unique bottle that can hold up against the pressure of the gas.


The abrupt release of pressure causes the carbon dioxide gas to leave from the liquid in the kind of bubbles when you open a bottle of champagne. That's why champagne is always served chilled, as this helps to keep the co2 gas in service.

So now you know how champagne gets its bubbles!
