Fermenting Lids for wide mouth mason jars. 4 waterless airlock fermentation lids kit. Easy Grip fermenter lid with Oxygen Pump automatically Vents air. Tracks ferment date. (4 Lids + Pump)

Disappointed

This kit has been invaluable in fermenting for me and gives me a Perfect Fermentation every time! The automatic venting valve makes it so easy - you don't have to do anything after you pump the air out. I have seen videos where the person pumps up and then takes the pump off to expel the air - you do NOT have do that with these - you just pump up & down as you would a bicycle pump and it works perfectly! I put the weight on, pump the air out, turn the dial and that's it! I Love these lids! There is no need to use any of my other lids because these are Perfection! Also the Customer Service is beyond what I would've expected. I wanted to solve an issue and the owner personally solved it with the most Caring, Excellent Customer Service - a company is only as good as it's Customer Service, in my opinion. I don't write reviews unless I am 100% sure of a product and this one definitely deserves it! Fermenting should be easy and fun and this kit makes it just that!

Highly recommended from a lot of recipes, books, and videos.

Tried using with glass weight but my ferment grew kahm yeasts! The product did not sucks up all oxygen. Disappointed.

So far the product seems to be working well. I’ll know more when the fermenting cycle is finished.

got these to replace the silicone lids that implode under pressure. sturdy and easy to clean.
