Sophico Silicone Fermenting Lids, Waterless Airlock Fermentation Tops Mason Jar Lid Fermenter Caps for Pickles, Kimchi, and Fermented Probiotic Food - 4 Pack, Wide Mouth (Jars Not Included)

These work really well! I'm fairly new to fermenting, but I've had great results using these lids compared to regular mason jar tops or the pop lids.

Muy útiles para fermentar

Bought these as they were one of the ones recommended by a fermenting pro as being safe and easy to use. Make sure you read the instructions on the box for using them though. I automatically assumed that they 'auto-vent' when the pressure builds up. Discovered one morning that the kimchi I had fermenting had lifted the lid and there was kimchi juice all over the table. Must have been quite a show! THEN I read the box and realized that you are supposed to press down on the middle of the lid once the fermenting starts once or twice a day (or whenever you see it starting to bulge) and THAT is what releases the gases. Lesson learned. But sure proved to me that these lids seal on the jars pretty darn well! Very happy with them.

Trouble free. Easy to clean.

Made my first batch of sauerkraut using one of these lids and I had no Kahm yeast. I did not have to monitor it for five weeks and sauerkraut was excellent.
