Fermentation Timeline Calculator

Estimate how long a typical vegetable ferment might take based on temperature and salt percentage.

%

Typical vegetable ferments are 2-3% salt.

Estimated timeline

7-14 days

Balanced: Typical vegetable ferment window with reliable acidity.

How to use this timeline

This calculator provides a typical range for vegetable ferments like sauerkraut or kimchi. Always taste and look for signs of active fermentation rather than relying on a fixed day count.

Use a clean utensil for taste checks, keep vegetables submerged, and move to refrigeration once the flavor is pleasantly sour.

Quick checkpoints

  • Day 1-3: bubbling starts, brine turns cloudy.
  • Day 4-7: flavor develops, acidity rises.
  • After week 1: taste daily until desired sourness.

Current temperature reference: 21 deg C (69.8 deg F)
