The formation of bubbles in Champagne occurs through a fascinating process. Initially, Champagne is a perfectly normal wine – it goes through the same steps as other wines, from grape harvest to fermentation. But then something special happens: as soon as the bottle is sealed, the second fermentation begins.
During this, the wine is mixed with a special filling liqueur (liqueur de tirage) that contains sugar and yeast. The yeast metabolizes the sugar, producing alcohol and carbon dioxide (CO2). Since the bottle is hermetically sealed, the CO2 cannot escape and builds up enormous pressure – up to six times higher than the bottle's capacity!
The champagne bubbles originate from irregularities on the glass surface. If you want more foam in your glass, serve the champagne in an angled glass.
There are about 1 million bubbles in a champagne flute.
But where are the foam bubbles?
You can't see them in the bottle, but they are coming! When you open the Champagne, these highly concentrated gas bubbles discharge in a flash. The cork literally pops out of the bottle, as the carbon dioxide bubbles finally want to reach the surface. When the bottle is opened, the cork flies out at 50 to 60 km/h.
Only then, when the Champagne is poured into a glass, can the fine pearls unfold and slowly but steadily rise to the top. A truly fascinating spectacle that further enhances the enjoyment of this noble drink.
