- Air kept out of vessels to prevent oxidisation of ethanol to ethanoic acid
- Requires zymase (yeast enzyme)
- Maximum conc. of ethanol produced is 15%
- After 15% enzymes unable to function
- Ethanol can be distilled from this mixture
- It's boiling point is lower then that of water
- To increase alcohol conc.
- Neutral pH
