Frequently asked questions about the airlock grommet
Does the grommet fit my fermenter?
It fits holes of Ø15 mm, which is standard on ordinary fermenting buckets.
Why is my airlock not bubbling?
Often because the gas escapes elsewhere, for example around the airlock. A new grommet and a well-fitting lid make the fermenter airtight again.
