Fermentation Principles

Salt controls microbial selection, water activity, and texture through osmotic pressure.

Oxygen management varies by ferment type—some need exclusion, others tolerate or require it.

Fermentation follows a curve, not a deadline—taste and adjust rather than following rigid schedules.

Temperature controls fermentation speed and flavor balance—warmer is faster, cooler is slower.

Sugar fuels microbial fermentation—some ferments rely on natural sugars, others benefit from additions.

Enzymatic fermentation breaks down proteins and starches, creating umami and sweetness over longer periods.
