Why it happens

Main causes

  • Low temperature
    Cold conditions slow down or delay fermentation start.
  • Incorrect salt ratio
    Too much salt slows fermentation, too little makes it unstable.
  • Lack of submersion
    Air exposure disrupts proper fermentation start.
  • Weak natural microflora
    Some ingredients contain fewer natural bacteria to initiate fermentation.
