Why it happens

Main causes

  • High temperature
    Heat accelerates fermentation and cell structure breakdown.
  • Low salt or acidity
    Weak brine does not preserve vegetable firmness.
  • Lack of tannins
    Leaves (horseradish, oak, currant) help maintain crisp texture.
  • Over-fermentation
    Even good cucumbers soften if fermentation is too active.
