How to Calculate Fermentation Time
What is Fermentation Time?
Fermentation time depends heavily on temperature - warmer temperatures accelerate microbial activity while cooler temperatures slow it down, often producing more complex flavours.
Step-by-Step Guide
- 1For every 10 degrees C rise in temperature, fermentation rate roughly doubles (Q10 rule)
- 2Sourdough: optimal 24-28 degrees C; refrigerator proves overnight = 8-12 hours very slowly
- 3Kombucha: 24-29 degrees C for 7-14 days; cooler = slower and more acidic
