This lovely cotton cover is an ideal kombucha jar cover and also works as a general fermentation cloth cover. 

Covering your fermentations with a cover is essential for protecting your creations from contamination, while letting the air flow.

Secure the fermentation cloth over your jar with the rubber band (included) to protect the contents from mould, impurities and pesky insects (we’re looking at you, fruit flies!)

Very useful for fermentations that require oxygen (aerobic), such as kombucha, kefir, vinegar, yogurt, ginger bug, cheese and more.

This usable and breathable fermentation cloth will promote optimal airflow while securely protecting your creations (as opposed to a cheesecloth, which can let fruit flies through). Choose only the best cloth for covering your kombucha and fermentations!

The rubber bands are sturdy and fit most jars.


  • Size: 25 x 25 cm (10x10'')
  • Contains:
    • One 100% cotton cloth
    • Two rubber bands

Nice quality.

Olivier Milette
It gives chic!

Very good quality, these pieces of fabric give chic to my fermentations on the counter and catch the eye of my visit! One serves me for my Kefir and the other I keep it for my Ginger Ale!


Perfect! I use it to make my Kefir of water or my kombucha

Pretty pretty practical filter

Complement your fermentation in a beautiful way!
By cons, I had to " stretch " by hand a little, they are woven tight and do not let enough oxygen to my taste.

Karen Mailhiot
Cotton filter

These are my favorite filters. Of course we can use any fabric pretty well but I like to see "Revolution fermentation" on my jars!
