FAQ

Do I need an airlock to ferment?

An airlock is the simplest way to let gas out and keep contaminants out. It's standard on home brew fermenters.

Does it need a grommet?

Yes. It seals into a rubber grommet in the lid or a drilled bung. Replacement grommets are available.

No bubbles: is something wrong?

Gas may be escaping elsewhere. Use a hydrometer to check fermentation progress.
