Fermented food jars keep cracking??

Well, I'm baffled!

Same. I use Ball or Kerr brand for everything I do with Mason jars (pressure and water bath canning, fermentation, etc.) and I've never had one crack that way.

I use the same wide mouth Bell jars. This is kind of nuts. How long are you fermenting for? I noticed mine goes a lot faster in the summer, even with air conditioning. Things could just be getting too intense in the jar. Maybe pull it earlier, or ferment in the basement if you have one.

Mine was fermenting way too fast this summer so I had to relocate it. I was using a gallon jar with just about a cup of feed. I wonder if the process is somehow sealing the lid because there is so much ferment in the jar and so little air space. Try the coffee filter instead and see if that helps. But keep us posted because this is a fun mystery

I only ferment for 3 days. It must be the jars. We bought them for a wedding and painted chalkboard paint on them; baking them for a period of time to set the paint. It must have weakened the jars. That is the only thing I can think of. Thank you to all who chimed in to try and solve the mystery!

Ok, I can see how a dry baking might have done it. Thanks for letting us know! This was really working on me.

Interesting! Are they breaking where they were painted?

No, just on the bottom.
