Awesome fermenting!!
10/08/2019 by Joan
This is a wonderful set, don’t wait to order it !! The silicone lids work awesome and I’ve made fermented sauerkraut, Italian tomatoes, and carrot cake in a jar so far!! Turned out superb! And I love the cabbage stamper ... what a great product for the new beginner to the more experienced fermenter! Thanks for the wonderful recipe book as well.... written so clearly and easy to understand! A very quality product, totally worth the money! And I was not paid for this review
Functional, works well

Everything you need to make nutrient-rich, good-for-the-gut ferments. These mason jar fermenting lids screw directly to mason jars, keeping out air while also letting gases escape—so you don’t have to periodically burp the jar. The kit also includes instructions, recipes, glass weights, and even a vegetable tamper to help release moisture from veggies directly in the jar.


Take the guesswork out of home fermentation. This mason jar fermenting lid creates the perfect anaerobic environment to make sauerkraut, pickles, kimchi, and other ferments.

There’s less daily maintenance, too, compared to other techniques. The lid keeps air out but is designed to let gases escape, so you don’t have to burp it every day. Plus, mason jars are pretty easy to get a hold of—you can even use ones you already own. Just screw the airlock lid onto jar and wait for the good bacteria to emerge.

Fermentation is good for you because of that bacteria. It can boost your gut health, strengthen your immunity, and improve your body's ability to absorb nutrients.

Whether you’re experienced or new to the craft, Masontops’ kit equips you with everything you need (instructions, recipes, glass weights, and even a vegetable tamper to help release the veggie’s brine directly in the jar).

Make room on your counter for your very own batches of fermented goodness. Your gut will thank you. more Their Story
