Mason Jar Fermentation Lid

  • About This Item

    Custom drilled plastic lid designed to pair with Wide Mouth Mason Jars (ie: Ball and Kerr Canning Jars). 


    Mason Canning Jars and Airlock are not included. Please purchase separately.


    Airlock lids create a one-way valve, allowing CO2 (naturally created from fermentation) to escape while inhibiting oxygen from entering your jar. This creates an ideal environment for fermentation and decreases the occurance of surface mold.


    For veggie fermentation, pair with a glass pickle weight or ceramic pickle weight.


    Lid diameter: 86 mm
