Big Mouth Bubbler 5 Gallon (18.9L) Plastic Fermentor

  • Details
  • Reviews


For primary fermentation of a 5 gallon batch you'll need a little more space at the top for the foamy yeast krausen, so a 6.5 Gallon Bubbler would be better.

Each Big Mouth Bubbler Includes:

  • Big Mouth Bubbler plastic fermenter
  • Big Mouth Universal Lid

You'll need a either a Small Universal Stopper or a  No. 6.5 Stopper.

We recommend using a Big Mouth Bubbler Harness to make moving your Bubbler easier and safer when it's full of wort or beer.

Important: Do NOT fill a plastic Big Mouth Bubbler with hot liquid. The fermentor is only rated up to 60˚C.

Capacity: 5 US gallons (18.9L)
Weight: 1.5kg
Height (lid closed): 56cm
Diameter: 26cm
Mouth Diameter: 14cm
Fermentor Material: PET

Free tip: Save the box and use it as a cover for your Big Mouth Bubbler to assist in maintaining temperature.

Welcome to big mouth bliss. Cooled wort can be poured directly from the kettle into Big Mouth Bubbler EVO 2. It’s also super easy to pitch yeast, as well as add ingredients (and take them out again). This 5 US gallon (18.9L) version is great as a secondary fermenter or for conditioning your beer, where reduced headspace means less oxidation.
