🔍 Spotting the Problem: How to Tell if Your Canning Jars Aren't Sealing Right

Spotting an improperly sealed canning jar isn't as daunting as it sounds. First, look for visible signs. If the lid is bulging or the contents are leaking, it's a clear indication that the jar didn't seal correctly. Is the lid still loose or can it be easily removed by hand? That's another sign of a faulty seal. You can learn more about this in our article on common canning mistakes.

Next, test the lid. Press the center of the lid with your finger. If it springs back, the jar isn't sealed. A properly sealed lid will stay concave after cooling and won't move when pressed.

Finally, listen for the pop. When jars seal, they make a distinct popping sound as the lid is sucked down. No pop might mean no seal. But remember, not hearing the pop doesn't always mean the jar isn't sealed. It's possible you just didn't hear it. Always confirm with a visual check and a lid test. For more information on this, check out our FAQ on what occurs if the lids don't pop during the canning process.

Steps to Take When Canning Jars Don't Seal Properly

  1. Inspect the Jar: Carefully examine the jar and lid. Look for any chips or cracks on the rim that could prevent a proper seal. Also, check the flat lid for any deformities.
  2. Test the Seal: Press the center of the lid. If it springs back, it is not sealed. A properly sealed lid will stay concave.
  3. Reprocess the Jar: If the jar is not sealed properly, you have two options. The first is to reprocess it within 24 hours. Remove the lid, check the jar rim for any food debris, wipe it clean, and then reprocess using a new, properly functioning lid.
  4. Refrigerate and Use Quickly: If you choose not to reprocess the jar, or if it still doesn't seal after reprocessing, refrigerate it immediately. Unsealed jars should be used within a few days to prevent the food from spoiling.
  5. Check Your Canning Method: If you're experiencing frequent sealing issues, it may be time to review your canning method. Ensure you're following all steps correctly, including filling jars to the correct headspace and processing for the recommended time.
