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)

We are huge fermenting fans, and did the traditional pickle pebble using the standard pickle pipe for a while but got tired of the messes. Inevitably the pipes would plug up and the pressure beneath sent an oozing mess up over the lid and down the sides of the Mason jars. We ended up with sticky messes everywhere. Then we came across these lids and thought "Genius!", the solution to our problem. Well, they have been! So glad we bought these. We've purchased several sets since. Additionally, the pump eliminates all oxygen which makes for a bacterial-free environment allowing the veggies to ferment in a very healthy, clean jar. We pump all the oxygen out, to the point that it's hard to pump at all, and that pulls up all the brine to make certain the veggies are covered, including the cabbage. We have found cabbage to be the most difficult to maintain moisture over the top due to our very dry climate which encourages the cabbage to reabsorb the moisture. Using these lids and the pump discourages the reabsorption and maintains fluid over the top where it is most needed. Since using these lids we have yet to find any yeast, kahm, mold, or questionable growth on our ferments, which is hugely reassuring. Whenever we do a taste test we test the PH with a pen first, and once done tasting and putting on the lid we reapply the pump to remove all oxygen inside of the jar. The sterile oxygen free environment makes all the difference for a healthy ferment. Overall we very much recommend these lids for serious fermenters. It simplifies the busy lives fermenters deal with due to juggling so many projects. Also, the date marker is a big plus for taste testing. The nice grip is another big plus for lid removal. They are very easy to clean, but we do not put anything into a dishwasher so there is no risk of residue being left inside our jars or sealing lids. It's much safer to hand wash, rinse and allow to drip dry. These are great for wide mouth jars, and we've used them on pint, quart, and half gallon-sized jars. Versatile and easy to store, too. Great product for fermenting!

I love this product! I use them to keep pureed food fresh longer. They work great!

They work as advertised! The little vacuum pump that’s included is a good little bonus. Really helps draw the O2 out of the fermentation jar (I use Ball canning jars). The lids, themselves, feel just a bit on the brittle side but, so far, quite happy.

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!

So I bought 2 different styles of fermentation lids and this one really stood out for the ease of getting the lid back off with the built in grip tabs. There was some negative reviews regarding using the air removal tool but I found that it was a great tool for removing air. I would put the tool into place, suck the air out, remove it and return the plunger to down position and put back into the lid to remove air again. I did this 3-4 times and you could feel the air come out as it got harder with each use. I removed the lid daily to mash the sauerkraut back down since I didn’t have a weight for my jars and my kraut turned out perfect! Great Quality and overall extremely satisfied with this purchase.

These fermenter lids by far are the best design I've tried yet. Easy to use , well made and good value , keeps air out and vents co2 . I do wish they sold the replacement silicone gaskets for the lids thought.

The media could not be loaded. These lids work like a charm I've been using them for years just to keep things fresh longer seeds milks juices. I never use for fermentation although that's what they're used for. Primarily I just used to vacuum seal my jars.Anyways I use them and love them. However my hands have gotten weaker over the years and it's hard for me to open jars. I accidentally found a cheat code and I thought I'd share with you guys. Simply scoot the tab to the side and you could release the air back into the jar making it easier to open.

Just started experimenting with fermenting peppers for hot sauce. Thought I would try these and they seem to work very well. They seem quite durable and provide a tight fit on widemouth jars.
