Elastic Kombucha Jar Cover

Protect your kombucha during fermentation with the Craft a Brew Elastic Kombucha Jar Cover, a reusable fitted cover designed for compatible kombucha fermentation jars. This breathable cover allows airflow during fermentation while helping keep out dust, debris, and fruit flies commonly encountered during kombucha brewing.

Designed as an alternative to loose cloth covers and rubber bands, the elastic edge allows for quick removal and reinstallation when taking samples, measuring pH, or checking fermentation progress. The fitted design helps simplify everyday kombucha brewing maintenance while keeping the fermentation vessel covered between checks.

The cover is designed for use with the jars included in the Craft a Brew Kombucha Starter Kit and Kombucha Jar with Valve. Fit may vary on other fermentation vessels.

Widely used by home kombucha brewers looking for a reusable fermentation cover, the Craft a Brew Elastic Kombucha Jar Cover provides a simple solution for managing kombucha fermentation setups.
