Stalled Fermentation: No Bubbles, No Tang

When ferments stop bubbling or tasting sour, temperature, salt, or starter issues are usually the cause.

Troubleshooting

Common Causes

  • Temperatures below 60°F (15°C)
  • Too much salt for the recipe
  • Chlorinated water or poor-quality produce
  • Insufficient starter culture

How to Restart Activity

  • Move the ferment to a warmer spot (65-72°F / 18-22°C)
  • Stir or press vegetables to release trapped CO2
  • Add fresh brine at correct salt levels
  • Introduce a small amount of active brine from a successful batch

Prevention Checklist

  • Use filtered water
  • Measure salt by weight
  • Keep jars in a consistent temperature range
  • Start with fresh, crisp vegetables
