Have you ever finished a canning session only to discover one or more jars didn't seal? It happens to every home canner at some point, and even after more than 20 years of canning and preserving food for my family, I still have an occasional seal failure.
In this video, I'm sharing the most common reasons canning jars don't seal, how to troubleshoot failed seals, and what you should do if you find an unsealed jar. We'll also cover simple habits that can help you prevent seal failures in future canning sessions so you can preserve your harvest with more confidence.
In this video you'll learn:
✔ The most common reasons canning jars don't seal
✔ How to tell if a jar has sealed properly
✔ How headspace, siphoning, and dirty rims affect your seal
✔ Why overtightening bands can cause problems
✔ What to do if a jar doesn't seal within 24 hours
✔ When it's safe to refrigerate, freeze, or reprocess your food
✔ Why I always remove screw bands before storing my jars
