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.

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!!!

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.

Super Produkt! Nachdem mir ein Glas Kimchi in der Küche explodiert ist habe ich dieses Airlock-System gekauft. Im Moment fermentieren zwei große Mason Jars mit Sauerkraut unter meinem Schreibtisch, und ab und an hör ich es zischen wenn Gas entweicht :DDie Airlocks sitzen super fest in den Deckeln und fallen nicht raus wenn man aus Versehen mal dagegen kommt. Alle Teile sind einfach zu reinigen und das Plastik ist ziemlich robust. Werde noch mal bestellen wenn ich meine Fernentier-Ecke vergrößere!
