what causes all of the bubbles in a bottle of champagne?

    Champagne is bubbly because sugars are fermented, forming carbon dioxide. The gas is released when you open the bottle.

    Champagne bubbles are the carbonation created during the fermentation process.  After the first fermentation, a little sugar is added to increase carbonation, and the bottles are stored for fifteen months or more.  Sometimes, instead of being bottled, the wine is placed into pressurized tanks to create the bubbles.
