This predrilled rubber bung will fit snugly into a traditional carboy or the lid of a plastic primary fermenter. Simply insert, attach your airlock and you are protecting your fermentation!
Please note: We will be closed on Saturday the 3-May-25. This will not affect shipping orders, they will ship Monday as per usual. For local pickups, I can be available Friday evening so that supplies for the weekend can be picked up. Feel free to reach out to me by email if you have any questions or would like to arrange an alternate time/date for pickup.
