Sauer System Fermentation Airlocks – Lids, Grommets, Gaskets, Stoppers – for Regular Mouth Mason Jars – 4 Pack

The "heart" of the airlock system is the Masontops lid. It is heavy-duty and highly resistant to absorbing any aromas or odors from fermentations. I have used Masontops lids on homemade pickled peppers and kim chi, as well as on other items for several years...and I am impressed with their quality! Integral to the lid is the thick, heavy-duty, silicone sealing ring, which is replaceable, should it need to be replaced. The sealing ring is also removable for thorough washing/cleaning. It appears that the silicone grommet in the lid is also easily replaceable, if that is ever needed. The airlocks are well designed...and the stopper plug for refrigerated storage without changing lids, completes the airlock system.I've been fermenting for decades...wine, beer, sauerkraut, chili peppers and full sour pickles. As with most things, I began with a "kit" or a "starter set" (model railroading, here). Kits are basically good to see if you are really interested in learning more about the "skills" needed to pursue that interest/hobby. So too, it was, with Mason Jar fermentation. Mason jars have their limits...they need "headspace", so whatever you are fermenting is limited to roughly 50%-80% of the jar's stated capacity...and "more" headspace creates fewer "issues" than "not enough", especially in the early, comparatively "violent" stages of fermentation. My first Mason jar "kit" included 3 lids with integral "waterless" airlocks, 3 fermentation weights (stones) and a vacuum pump (large syringe)...and a recipe book which, well...it is what it is, as it were. Air, particularly oxygen and the air-borne, wild bacteria and mold spores, are NOT friendly to fermentations; and the vacuum pump was a bit of a "joke"...more "well, it won't do any harm"; but I seriously question it's functional value. Basic rule is that you don't break a fermentation "seal" unless there is still a sufficiently active ferment present that will re-establish the necessary carbon dioxide "buffer" in the headspace. "Sampling" actively fermenting foods, including wine or beer, reveals precious little about the finished product. Fermentation is complete when it's done...and not before...period. That said, there is really nothing safer than a properly maintained, water-filled, correctly functioning airlock for a "closed system"...in this case, the jar and the lid/airlock with the sealing ring. I will state that I am NOT interested in the probiotic value/benefit of the fermented foods, I ferment for TASTE...my goal is to make them shelf-stable (sterile canning) or refrigerate them for relatively immediate consumption upon the completion of the ferment. The ONLY truly usable item that I found in the original kit was the fermentation weights with their molded-in "finger grab"; but even with most wide-mouth Mason jars "of size", there is still a small shoulder to contend with, so that may pose challenges, depending on what one is fermenting. Fermentation "springs" and "gates" may offer increased functionality for some food items. Needless to say, my first Mason jar fermentation kit was quite disappointing; but at least I learned what NOT to buy/use!The waterless, one-way airlocks may have their place for some folks, but NOT in "my kitchen"! There is no visual indication that they are functioning...and they are rather easily subjectable to damage that may not be easily discernable. I and my wife have reached an age where "large scale for home use", crock-based fermentations of sauerkraut, peppers and pickles result in far more than we can use. The amount of canning and/or refrigerator space requirements means that large-scale fermentations are simply NOT as much fun as they once were! Mason jar ferments are small enough to make it all FUN again; but even on a small scale, there is absolutely no substitute for quality components and "sound" fermentation and preservation practices.Fermentology's Sauer System lids and airlocks ARE the quality components that you really need to make every ferment as successful as it can be!!!

I love the ease of use of these wide-mouth mason jar lids for fermentation. I have been fermenting without the one-way gas exit systems, but have had a few mishaps with kahm yeast growing where brine submerging wasn't maintained. While not dangerous the taste is, well, off. This system has resulted in perfect fermentation. I am still using glass weights to push the veggie materials to submerge through the brine, but as I understand, I may not need to do this as oxygen cannot enter. That makes it even easier to use. The addition of "plugs" to use so that the lids can be used to store finished product is a plus. Not sure I would use it as I prefer to transfer to nice pouring bottles.

The plastics used are high quality will get the fermenting job done. I will order them again.

Getting ready to use them today. Appear to be good enough

There are a few different versions of vent lids for mason jars and I prefer this one. The seals are good and easy to maintain and the lids and water check valves are fairly well made. They are thin plastic and can break if dropped or hit, but are great for their intended use. I prefer this type of vent because I can see what is going on and I trust the mechanical part where it is simply a small thimble placed over a tube with water around it forming a seal. Easy and simple. Other versions have a silicon flapper or device which is to allow CO2 out and no oxygen in...I can't verify this is the case...what if a small piece of debris is introduced to the flapper seal? It could possibly hang up and leave an opening to allow oxygen to be introduced into the jar. This set up is a tried and true method and is basically how fermenting pots are designed.

I have purchased these products before, so I knew what I was buying. These are excellent products for fermentation which work with Mason jars of any size with wide mouths. So simple a caveman could do it! But the fantastic thing is my package had come open due to uneven taping. One of the airlock packages also had opened inadvertently and two stoppers were missing from package. I let the seller know and requested replacement of the two stoppers. With no questions asked, the seller not only replaced the stoppers but actually mailed me an entirely new and complete set of 4. So very thoughtful and kind. This seller is someone who will ensure your satisfaction. I highly recommend this seller and the Sauer products.

I wanted to do some small batches of mead to test flavor additives, and was thrilled to finally find lids and airlocks for regular sized (not wide mouth) canning jars. They're mostly plastic but seem to be well made (not cheap and flimsy). Everything seals well, both lid to jar and airlock to lid. It comes with stoppers for the lids if you want to plug them while not using the airlocks. These also fit into carboy bungs, so you can get a bit of double use out of them if you do larger scale fermenting.I'm enjoying them so far. Would definitely recommend!EDITED ADDITION:- The small lids for the airlocks fit so tightly that it's a frustration to get them off without getting liquid everywhere. Probably not an issue if you don't use them regularly, but it's a noteworthy frustration if you're planning to use these a lot.

I used a 1/2 gallon Wide Mouth Mason jar for an experimental batch of blackberry mead and the lid and airlock worked great. One thing to be careful with is tightening these down too hard which can make the lid pretty difficult to remove after fermenting for a few weeks. The gaskets are very good and you just need to trust hand tightening.

Got these to ferment my Ginger Beer colonies and fermented beverages. These are great airlock lids for mason jars. The grommets are tight and stay tight. The seal is solid and they screw on tightly. Never had an issue with these.

This is a nice kit I use for fermenting and have re-purchased a second one already.

Quando hai voglia di preparare piccole quantità di fermentati particolari e la pentola di fermentazione (la mia è da 7 lt.) è troppo grande sono l'ideale.Occhio alla gomma di guarnizione e ai tappini che prendono l'odore del fermentato ed è difficile toglierlo. Nel mio caso, ad esempio, il tappo delle cipolle fermentate è compromesso :-)Sono perfetti per i barattoli tipo 4 Stagioni, sui barattoli normali non vanno.

This is a very good system for fermenting small batches imo, especially if one is into canning too, because jars become multi-purpose.I have five on the go currently, and I will be adding today's picked gherkins, and would have more fermenting if it wasn't for one major issue - Amazon Prime are now using Evri and our last few orders of this product have disappeared/been returned. Anyway, rant over.The lids are solid and easy to clean and beat any other small-batch system that I have used by a country mile. For large batches I use traditional crocks, but wouldn't hesitate to use these if I had suitable >2litre jars. Their glass weights are good too.

Ich habe das Set gleich zweimal bestellt. Bei der zweiten Lieferung fehlte ein Teil und ich habe super schnell kostenlosen Ersatz erhalten - großartiger Service und top Kommunikation!Einfache Bedienung und hochwertiger Eindruck!Tut das, was es soll ...
