A mixed pack of 20 Rubber Bungs by Almost Off Grid.

10 of the bungs have a bored hole, 10 of them are solid. Rubber bungs are used in homebrewing to prevent air and contaminants from entering the fermentation vessel.

Each rubber bung fits snugly into the neck of a standard-sized glass demijohn. The bored ones have a pre-bored hole into which a standard airlock fits. Solid stoppers can be used to seal a demijohn after all fermentation has finished, allowing the contents to 'bulk' clear and mature rather than bottling straight away. 

Ideal for wine, mead and cidermaking and all kinds of fermenting.

20 standard sized bungs, 10 solid and 10 bored with a hole, in each pack.
