Product Description

We set out to develop an all silicone fermentation lid, but quickly realized it would work just as well as a straw hole lid!

Before these lids, we were using Ball plastic lids with a hole, a silicone grommet to hold the airlock, and a silicone sealing ring to make them airtight. Eventually the plastic would crack or break, and it was fussy to assemble all the pieces. This single piece of silicone replaces the lid, grommet, and sealing ring! They are easier to use, easier to clean, way better looking, and double as a tumbler lid when you aren’t fermenting anything!

For a complete lacto fermentation setup, pair this lid with an airlock and a glass weight. More fermentation instructions are coming soon, but for now they are widely available on blogs and other websites.

Made from 100% food grade silicone rubber and 18/8 304 grade stainless steel.
