2x 5 litre Fermentation Buckets with bored lids, grommets and airlocks by Almost Off Grid. Food grade primary fermentation vessels for use in beer, wine & cider making. Each brewing bucket has a tight-fitting lid with a bored hole, fitted with a grommet. The airlock supplied with the bucket and lid fits in the grommet. The airlock has a red dust cap designed to sit loosely on top of the airlock to keep out dust and fruit flies. The cap is not designed to be tight fitting. These buckets are ideal if you prefer to ferment your homebrew in brewing buckets rather than demijohns. The bored lid avoids the need for a bung as the airlock fits directly into the vessel. The buckets are big enough for all 4.5 litre (6 bottle) wine kits.
