Learning objectives
  • Fermentation Basics

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.
