Fermentation Time Rechner — Formel
## How Fermentation Time Is Estimated
### Key Factors
- **Temperature**: Warmer environments speed up fermentation. 65-75°F is ideal for most lacto-fermentation.
- **Salt**: Higher salt slows fermentation. Standard sauerkraut uses 2-3% salt by weight.
- **Ferment type**: Each type has a different base timeline.
### Base Times (at 70°F, 2.5% salt)
- **Sauerkraut/Kimchi**: 14-28 days
- **Kombucha**: 7-14 days
- **Yogurt**: 8-12 hours
- **Sourdough starter**: 5-10 days to establish

Lösungsbeispiel
Estimate sauerkraut fermentation time at 70°F with 2.5% salt.
- Base time for sauerkraut = 21 days.
- Temp factor = 70 / 70 = 1.
- Salt factor = 1 + (2.5 - 2.5) x 0.2 = 1.
- Ideal time = 21 x 1 x 1 = 21 days.
- Minimum = 21 x 0.7 = 14.7 days.
- Maximum = 21 x 1.5 = 31.5 days.
