Pickle Pipe - One-Piece Silicone Waterless Fermentation Airlock Lids for Mason Jar Fermentation - Regular Mouth - 4 Pack

I'm thrilled with these! And they arrived much earlier than I expected. :)

These fermenting lids work great. I have a set of the wide mouth jar ones and they work so well that I purchased these regular mouth jar ones. Currently being used for my fermented ketchup that has a tendency to burn it a regular jar lid is even slightly too tight. Since they are silicone, they are non staining and I don't have to worry about outgassing or the acidy ferments damaging them and ruining my fermenting. They are way easier to use than standard fermenting lids. If I am making multiple versions of a certain ferment I can colour code it with the coloured lids based on the recipe I am using. Highly recommend.

Permite usrlos en los botes de Mason Jar, permiiendo que respire sin tener que abrir el bote, totalmente recomendable, estoy entusiasmada

These are so easy to use, a perfect tool for ensuring beginners (like me) get good results. I've made small batches of lacto fermented cucumbers, jalepenos, zucchini, and green tomatoes and all came out well with no sign of the white yeast that had been plaguing my pre-pickle pipe ferments. Great design - I love the simplicity of this airlock. Throw some vegetables and brine into a Mason jar, top with pickle pipe, and forget about it for a week. Foolproof.

Great for pickling. These caps let the air out without letting air in. Unfortunately, they also let out juices so still important to keep a close eye on sauerkraut, etc.
