JILLMO Stainless Steel Fermentation Lids for Wide Mouth Mason Jars, 4 Pack

I'm absolutely thrilled with this fermentation kit! The stainless steel lids are high quality and fit my wide mouth mason jars perfectly. The airlocks work flawlessly - they let the CO2 escape while keeping oxygen and contaminants out, which has resulted in consistently successful ferments. What I love most is how easy this kit is to use and clean. Everything I needed came in one package, and the silicone grommets create a perfect seal. I've been fermenting sauerkraut, pickles, and kimchi with zero issues - no mold, no failed batches. The stainless steel construction feels durable and looks professional in my kitchen. It's also a much more sustainable option than constantly buying fermented foods from the store. If you're new to fermenting or looking to upgrade your setup, I highly recommend this kit. It's made the whole process foolproof and enjoyable!

These are great. Used once to make pepper sauce and have the second batch “cooking” now. Super easy to setup and use.

These are mostly great, but got a little yucky by the end of a 2-3 week fermentation. I would’ve given them 5 stars if the material (stainless steel) were more solid—this steel felt light, thin, and somewhat flimsy, but the gaskets and plastic components worked great, and because they disassemble easily, cleaning was quicker and easier than I expected. Definitely better than trying to use regular mason jar lids and trying to “burp” them regularly (what a pain). The juices did overflow a bit, but otherwise it was trouble free. Highly recommend storing them in a sink if you’re able to, makes any brine leaks a minor issue, vs. staining or damaging the countertop.

Very well made and worked well for my first attempt at making fermented food.

I love these fermentation lids and it happens to be the best quality stainless steel.....these are the best that i've ever had...also the price is super

Love em works great

It took me a long, long time to gather the courage and initiative to try fermenting hot peppers. Because of the extraordinarily hot summer and long growing season in 2022 I harvested the last of my hot peppers in November. I started four 16 oz jars of these with a 3% brine (using a scale). I let them ferment for three months and there was not a speck of any kind of mold or fungus on them whatsoever. I did see a bit of whiteness settling at the very bottom of the jars and was afraid it was that kahm yeast I’d heard about; however, after some Google research I discovered that it is nothing more than some of the normal bacteria dying off (due to having unfavorable conditions) and is totally natural in the bottom of the jar. And the peppers are divine! I blended some up into hot sauce and others we add onto sandwiches etc. I’ve already ordered a few more sets and I am super excited to try making sauerkraut, kimchi, radishes etc. I know people do ferments without these special gadgets but I would so much rather use them and have perfectly clean ferments then have to scrape off some mold, because every time I read somewhere to “just scrape off the mold” it makes me feel a little bit funny inside.

After you have done a few beginner ferments, this is a great product for the next stage of your fermentation journey. I use these regularly now, and the ferments have gone for months. I like the seal.

الأسف مخيب لآمال ☹️ الغطاء مختلف عن الوصف الغطاء لا ينفصل وفتحت الغطاء مو نفس مقاس الأنبوب الأنبوب اكبر من الفتحه …. أحسه اقرب لغطاء كوب عصير ومالقيت ولا برطمان مناسب لها 💔 بس الأنبوب ممتاز كما بالوصف رجعته لانه السعر غالي إذا بس ابي استخدم الأنبوب بدون الغطاء

There are no jars that fit these lids! I’ve tried numerous local shops and online shops but I can’t find any that fit.

Cumplen bien su cometido y son una herramienta muy útil para fermentar en frascos. En mi caso preparé col agria. Resuelven el problema de tener que estar abriendo los frascos para dejar salir el gas que se produce por la fermentación y también el consecuente rebosamiento y derrame de líquido (salmuera). Hay que hacer caso de la indicación de dejar un espacio adecuado entre el nivel del producto que envasemos y la tapa o se corre el riesgo de que el líquido se suba. Aclaró que no incluye los frascos y que los frascos deben ser de boca ancha, de 86 milímetros de diámetro (8.6 cm). Recomiendo este producto

Works well

O tamanho da tampa é muito pequeno, isso dificulta a possibilidade de encontrar potes de vidro que possam ser usados. Mas o AirLok funciona perfeitamente bem.
