perfect for small batch

For small batches of unique pickles (instead of large crocks), this is completely perfect. The fit is exactly right and the depth is good to prevent mold by trapping vegetables well below the surface. Easy to place in and easy to dump out.


Wish I’d had these last summer

The Masontops Story

Masontops | Mason Jar Fermentation

Good for the Gut

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.
