What You Need to Know
During fermentation, yeast enzymes such as invertase and alcohol dehydrogenase hydrolyze sucrose into glucose and fructose, which are then metabolized via glycolysis to produce ethanol and CO₂. The process also generates minor organic acids that help maintain a slightly acidic environment, inhibiting unwanted bacterial growth.
The Science
Primary Reaction
