316 Stainless Steel Fermentation Lids | 3 Silicone Waterless Fermenter Airlock Lids | Easy Lacto Fermenting Wide Mouth Mason Jar Canning Lids | Free Recipe eBook Included

I just today opened my first jar of sauerkraut made with these lids and the tempered glass weights that Mason Jar Living sells here on amazon and I'm really happy with the sauerkraut I had with lunch. Delicious! I followed a recipe that was in a link provided by Trellis and Co. which made it super easy to put together a batch of kraut in a quart mason jar. I'm impressed with the lid. I don't have experience to draw from but all I can say that for my first time fermenting these lids made things really easy. I love that fact that they're stainless steel and that they'll last a while, hopefully the silicone valve will remain available for as long.The one thing that I have to mention, and the reason I can only give four stars, is that the lids I received are a little bit out of round. I measured one today and it's about 3//32 of an inch out of round. The lid works fine, conforming to the jar as it's tightened. It just bugs me when I put a lid on a glass jar and it binds a bit upon tightening. I think this is a great product. I've got six weights and three lids so I'll probably get three more. My first ferment went really well.UPDATE 8/2/17 I thought I would come back and update my review after using these for a few months. I originally bought 3 lids and found that I was running out of sauerkraut too often, so I bought 3 more and have been eating sauerkraut a couple times a day for a few months now. It's very healthy stuff, good for the mood also. I don't buy probiotics in pill form anymore. I'm impressed that I have not had one failure, not one bad batch with these lids. I've lost count on how many batches I've made, well over a dozen. It's important to leave a little room(1/2-3/4") at the top of the jar so the brine has a place to go instead of out the vent. I also add salt by weight, using a 2% ratio of salt to cabbage. If it's warm I use a 2.5% ratio and all has gone well. I'm using the method I learned from the website Trellis and Co. turned me on to(make sauerkraut dot com), basically for a quart jar it's 800 grams of cabbage to 16 grams of sea salt (I use Redmond Real Salt). Great product, can't wait to try out the new springs!9/9/19 updateI've been using these new thicker (better!) lids along with the pickle helix for several batches of sauerkraut now and I am very happy with how these things work. I have not used my glass weights since I've tried the helix (springs) I still use the original Trellis + Co. lids I bought a couple of years ago and they work just fine. This new version lid is thicker and better, easier and more pleasant to use. Excellent product, well done Trellis + Co. !

Despite what I consider to be a minor flaws, these are excellent. I do not like how the silicone "seal" can be pushed out by the contents. Even so, I've had excellent ferments and NO RUST. They are compact, rather than using other types of lids, making storage easier.If their was a glass weight that had a recess to prevent contact, I think that would be ideal. Also, deepening the depression or somehow raising the sides to allow more liquid to collect and not spill on my counter tops would be great, but a towel currently solves that.I have also reviewed their regular lids, which are of equal quality. I would purchase these again, even at the price, which I consider a little high.

These work great for fermenting. Use them all the time. I would buy more.

They work well for the first use, but it is very easy to damage the airlock while cleaning. The silicone pops out of its holder extremely easily, and can not be reattached. Would not buy again.

I was unhappy with these. They rusted after the first use.

Great design! Great rust-proof stainless steel base. Sleek design as opposed to bulky external fermentation locks. This one just as well as the external types to keep my jars and my ferments safe, and I actually prefer it to the others, as it is more convenient when I have to open to stir then replace the lid. I love that they came in compostable packaging, that really makes me feel as though the seller cares.

works well, easy to clean.Rusts if you fill your jars and do longer ferments.

These lids make fermenting easy. There are several lids to choose from. I went with these because they are easy to clean in the dishwasher or washing by hand. I read reviews on some of the other lids, that there were multiple pieces and issues with sterilization. These lids work as advertised. Sauerkraut is bubbling away and the lid is releasing those gases. That way I don't have to check on it daily and remove the lid to "burp" my sauerkraut.
