Assumed audience
- Reading level: general adult.
- Background: no chemistry required.
- Goal: understand what fermentation is and why it works.
What fermentation is
Fermentation is a process where microbes consume sugars and produce new compounds like acids, alcohol, and carbon dioxide.
The main players
- Yeast: converts sugar into alcohol and carbon dioxide.
- Bacteria: convert sugar into acids (like lactic acid).
Conditions that matter
- Sugar: food for microbes.
- Temperature: affects growth speed.
- Oxygen: some fermentations need it, others do not.
- Time: changes flavor and safety.
Safety basics
- Use clean tools.
- Use fresh ingredients.
- When in doubt, discard anything that smells rotten or moldy.
Why this matters
Knowing the basics makes it easier to control taste, carbonation, and the risk of spoilage.
