Nourished EssentialsEasy Fermentation Kit - 3 Pack Airlock Lids for Mason Jars Wide Mouth with Vacuum Sealer -Easy Fermentation Lids for Sauerkraut Making Supplies, Kimchi, Pickle, and Kombucha

This product is utterly fantastic and the customer service is the best that I have experienced online thus far. I just now decided that tonight I am going to throw out my three-piece air-locks and the entirely useless plastic cup inserts that I have used previously. I will also add some pictures of my current ferments.I have been using the Easy Fermenter Wide Mouth Lid Kit with the pump for about 2 months now and I am very impressed. For reference and comparison, I have been using quart and half-gallon Ball mason jars with these lids. I have made multiple batches of kimchi, beet kvass, and apple cider vinegar and the process could not have been simpler. After 7 days, the kimchi was ready to go, and after 10 days, the kimchi was perfect. I plan on making water kefir again, as I have not done so with this system, and I anticipate that it will work wonderfully.The construction of the lids is simple and straight-forward, and therefore very easy to clean. All of the pieces can be separated from one another so that you can prevent any mold to form in the seal or under the date dial. I've put the hard plastic in the top rack of the dishwasher, but I am reluctant to expose the rubberized seals to that heat.It has been stated that one does not need to use the pump at the beginning of the ferment, but I do and I will tell you why. Although I am confident that the oxygen will be forced out swiftly, I do want to remove as much as possible from the jar. Using the pump at the beginning also assists in forcing air bubbles to the surface of the brine that may have been captured below the food matter, and the vacuum also forces dissolved gases to expand and escape the water to the surface. The effect is actually pretty cool to witness. After pumping the air for a bit, I usually spin the jar like a washing machine to allow more trapped bubbles to rise up, then I pump again for good measure.There are two issues that I would like to point out, and one suggestion to the manufacturer.One, just last night, the seal on my pump slipped off and is is irreparable. However, after looking into the questions portion of this listing, I discovered that Nourished Essentials will issue a replacement for the pump, as they are not sold separately. They asked me to go to their own website and provide my address, which I did. They responded most rapidly to thank me, inform me that they will process my replacement in 1-2 days, and also throw in another lid for my inconvenience. This is astounding to me and has earned my loyalty.Two, I had a hard time getting the lids off a couple of times, but it was my own fault. I have a habit of over-tightening lids and I did so in this case. I have since held back my Herculean tightening abilities and it has had no detrimental effects on the fermentation.Three, I believe that adding a "Month" ring on the lid would be a benefit. There are some longer ferments (like several months to a year) that I am curious to try, and I would appreciate the addition. This is not even close to a complaint, as it is entirely unnecessary and there are easy alternative solutions.If you are interested in fermenting, do not hesitate in your decision to buy this system. This system is progress and simplicity in a compact package, and I mean that literally. If you need one more incentive, these guys wasted all of 2 cubic inches MAYBE in their shipping container, which made me happy before I even had a chance to use the lids. I hope that more companies will function even half as efficiently as these guys do.

I began fermenting about a year ago. I started with mason jars, burping them every day, sometimes twice a day. I considered using the standard air locks (the ones that use water), but I noticed they can be messy. One day, I came across these lids. At first, they seemed too good to be true. I never have to burp my jars, and there would be no mess from water bubbling out. I decided to give them a try. I was surprised how easy they are to use, and how well they work. Just as advertised. No mess, no burping, no worries. Here's how it works:1. Pack your jars2. Put the lids on and hand tighten3. WaitThat simple. Of course, the kit does come with an air pump, which may be confusing for some people. I'll explain the pump:Using the pump when you first pack your jars is NOT necessary. During the first stages, the gas(CO2) created by the bacteria will push the oxygen out of the jar pretty quickly. When you DO want to use the pump is toward the end of your ferment, (when bacteria have slowed their growth and metabolizing), and you open your jars to do taste tests. If you decide to let your ferment go longer, then you'll use the air pump to pull the oxygen out, since it wont be pushed out as fast as it will in the beginning. Only ONE pump is all that's needed.Overall, theses lids are perfect for all levels of fermenters. I will be buying lots more of these, and would definitely recommend them to everyone.

I'm loving the lids. They are the easiest airlock system yet and it's really nice to have just one piece to worry about.So today, my first fermented item is done. It's a short-fermented salsa. It's the first time I've fermented salsa and it's great! Even my wife, who doesn't like fermented foods, likes it! I did have a problem with the lid on the salsa in that it sticks and was very hard to remove from the jar. I found that maybe I had pumped it too hard to remove the air from the previous time I opened it and maybe tightened the lid too much then also. But the other two lids don't seem to have any problem and this one just doesn't turn easily, but it is usable.My cabbage/sauerkraut looks and tastes like it's going along really well. And my onions are progressing well also. Both of them are long ferments and won't be ready until at least the middle of the month.These lids are going to replace my big, jumbled box of lids with holes in them and airlocks and such for fermenting. The old airlocks never have worked well for me.And now, if I could find something better than a baggie with water or a ceramic weight to weigh down the food in the jar (my jars are not round), I'd be all set up. I'm thinking something "like" a baggie with water, but maybe made with a cloth (or silicone) bag with weights (marbles) in it so it adjust to the shape of the jar. Although... So far, my ferments using the Easy Fermenter without something to hold the food down is working quite well. Since the air is pumped out, the contents stay wet even though they are not under the brine. I just shake them up a bit each day.As to that pump idea. It's really smart. If you have a jar to ferment that is not full enough, so the process would have to push out a lot of air, use the pump right away to help keep the mold, etc. from developing. And the best thing about it is that you can take the air out that you introduce when you just can't resist tasting as you go along. I love the pump particularly.

Ever buy a product you were excited to use, but the user's guide was a bit unreadable? The product itself seems useworthy, easy to screw on (pickling 3 jars now) etc, but the user's guide print is so light I can't read it! Instead of a light gray/black print using such a tiny sized font, it should be in bold contrast colors with a bold type. Fermenters are all ages, best to accommodate the older folks , Please!

Perfect thank you

Ya he fermentado unos 10 lotes y no he tenido ningún problema con ninguno, las tapas funcionan a la perfección. Lo único es que no son compatibles con la marca Fido, pero sí con los frascos de la marca Quattro Stagioni que venden en el AlCampo.

Je connaissais déjà ce système de couvercle avec valve et c'est vraiment bien de pouvoir les acheter séparément.Cependant il serait bien d'indiquer plus de détails sur la compatibilité des couvercles car j'ai du acheter deux bocaux "MASON" 10€ pièce... Alors que au final ils ne sont pas compatibles.Le diamètre est bon mais pas le filetage.Donc si vous voulez des bocaux compatibles et pas chères utilisez ceux de la marque italienne BORMIOLI, en 86mm !Sinon pour l'étanchéité et le reste je vais voir ce que ça donne avec un bocal de choucroute...

Fit Borlio jars like a dream and the excess brine that erupts on times collects on the top instead of on the worktop. Makes the fermenting process so easy

No flimsy plastic lids, but ferm and solid and well designed. Fits wide mouth mason jars (8,6cm). Not that my kimchi tastes better now, but fermenting is now controlled without worries. Recommended product for fans of vegetable/fruit fermenting.
