Why it happens

Main causes

  • Poor sealing
    Even slight lid misalignment or thread defects can break the vacuum seal and cause leakage.
  • Worn or low-quality lids
    Lids with scratches, deformation, or weak coating often fail to maintain a proper seal.
  • Improper sealing technique
    Incorrect tightening, placing hot jars on cold surfaces, or reusing lids increases the risk of seal failure.
