How is ethanol made?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Ethanol is produced through two main methods: fermentation and synthetic production. Fermentation involves yeast converting sugars from crops like corn, sugarcane, or grains into ethanol and CO2. Industrial ethanol is also made synthetically from petroleum-derived ethylene. For beverages, only fermentation-produced ethanol is used.
