Risk Assessment

TemperatureOptimal

Ideal range. Lactobacillus dominates, steady acid production, best flavor development.

Mold risk (oxygen)Low

Excellent. Airlock eliminates oxygen exposure. Lowest mold risk possible.

LightNone

Perfect. Dark storage preserves nutrients and maintains consistent temperature.

Chemist's note

These are estimates based on published fermentation data. Your actual results depend on the specific bacteria present, produce freshness, and water mineral content. Always verify with a pH meter before eating. The number is more reliable than the calendar.
