This process relies on the production of certain enzymessuch as those involved in glycolysisto break down the chemical components in a substrate. within a week or two of pitching the yeast. Some advanced fermentations and processes may take longer. }); As the yeast breaks down the sugar, it emits CO2 and when it can no longer dissolve in the beer, the excess CO2 is released into the air, causing the beer to bubble.
