Sophico Silicone Fermenting Lids, Waterless Airlock Fermentation Tops Mason Jar Lid Fermenter Caps for Pickles, Kimchi, and Fermented Probiotic Food - 4 Pack, Wide Mouth (Jars Not Included)

These fit wide mouth jars perfectly. I love that they’re one piece, dishwasher safe, easy to use, work well, and cute. They’re made for pickling, so with enough internal pressure, gasses can escape from the little flaps at the top. You could probably fit a straw through the opening too. I use these as a plastic free storage solution and mainly have fruits or leftovers and the seal is enough that nothing dries out in the fridge.

I like these lids. The best of all I’ve used. They work perfectly.. what can I say easy to use on no fuss.

These are perfect for fermenting Good price and easy to use

Work great/ they do lift a little with the buildup of fermentation so you need to remember to “burp” them. Does retain some of the smells in the silicone.

Love these things. Storage capacity - they fit pint & quart wide mouth mason jars perfectly, they’re durable (I’ve washed them many times), used as intended they don’t leak, and it’s handy having multiple colors when the ferments start getting foggy (dill pickles). Plus - no rusty rings! I’d definitely buy these again.

I LOVE these!!! I filled my jars to the top and I probably should have left a little room. Next time I will not fill them so high to where the juice comes out when I push to let the air out. Actually, they seal very nicely. I appreciate the colors so I can tell the difference in jars. I can use them to store things in various size mason jars as long as it is Wide Mouth. They are very easy to clean, don’t take up much storage space and are good quality. I really like them and I will buy another set.

Best product for fermentation I have ever used! And they are so cute too!

I bought these , which fit inside the mouth of the jar, and also the ones that stretch over the mouth of the jar. I made pickles side by side in 1-quart wide-mouth canning jars. I used glass weights to hold the vegetables under the brine. All the pickles turned out great. These have flanges that are supposed to grip the inside of the jar mouth. For the first few days these rose up a little but did not come out of the jar completely. I just pushed them down, with some brine coming out of the opening each time. After that they stayed in place. I didn't think that was a big deal since you're supposed to look at your pickles every day anyway, and you should always keep your pickle jars on a dish to catch any drips while fermenting. I can't address how long these things last because I've only used them once. Given the price differential I would be happy getting these instead of the other kind.

Muy útiles para fermentar

Bought these as they were one of the ones recommended by a fermenting pro as being safe and easy to use. Make sure you read the instructions on the box for using them though. I automatically assumed that they 'auto-vent' when the pressure builds up. Discovered one morning that the kimchi I had fermenting had lifted the lid and there was kimchi juice all over the table. Must have been quite a show! THEN I read the box and realized that you are supposed to press down on the middle of the lid once the fermenting starts once or twice a day (or whenever you see it starting to bulge) and THAT is what releases the gases. Lesson learned. But sure proved to me that these lids seal on the jars pretty darn well! Very happy with them.

Trouble free. Easy to clean.

These tops are a very clever design. I would have loved to be able to use them for my Super Gut yogurt fermentation. I have a lot of silicon products in my kitchen. None of them have an odour, however these tops have a strong smell which makes me question what material they are made of, and are they food safe. I will be returning them, sadly.
