Superior to a carboy, the Big Mouth Bubbler® Plastic is a virtually indestructible fermentor, equipped with 3″ thick anti-flex ribs, a punted bottom and decreased base diameter for extreme strength and durability. Its smaller footprint preserves precious brew cave space and allows for convenient storage inside a standard brewing bucket.

The punted bottom promotes crystal-clear beer by efficiently settling out yeast from finished fermentations. Graduation marks make volume measurement instant and effortless. And, of course, its revolutionary wide mouth eliminates the nightmare of cleaning and sanitizing by giving you direct hands-on access to attack crusted krausen, while simultaneously offering unlimited flexibility in dry-hopping and flavor additions.

Included:

  • Big Mouth Bubbler® – 5 Gallon Plastic Fermentor
  • Single-port universal lid

Required, not included:

  • Small Universal Stopper 
  • Airlock 

The Big Mouth Bubbler® Plastic prevents off-flavors by enabling you to keep the lid on during testing and transfer, avoiding exposure to oxygen with standard-sized ports that can accommodate most fermentation-monitoring equipment. Best of all, it will not shatter when dropped or knocked. 

The new Big Mouth Universal Lid (included) fits all Big Mouth Bubbler® Fermentors. The Big Mouth Bubbler® Universal Lid is just like a traditional carboy bung, only bigger! Just as easy to sanitize and set in place too. Ribbed silicone rings ensure a positive seal to keep out pests, while the non-threaded design allows the lid to move preventing an out-of-control fermentation from dangerously pressurizing your fermentor.

Lid ports work with our Small Universal Stopper or a standard 6.5 rubber stopper.

Important Note: Do not fill any Plastic Big Mouth Bubbler® fermenters with very hot liquid – temp should not exceed 140 degrees Farenheit (60 celcius)

Note: We recommend a soft cloth for cleaning the inside. Standard carboy brushes will scratch plastic fermenters leaving places for grime to hide. A warm cleaning solution will suffice. Do not use hot water on plastic fermenters of any sort. The Big Mouth Bubbler® is compatible with a standard carboy dryer when the dryer is used inverted.

*Pro Tip: Save your box and use it as a cover for your fermenter!

5 gallon fermenters are best for the secondary conditioning stage of beer fermentation. The smaller size eliminates extra airspace in the fermenter reducing the chances of oxidation which can stale the beer prematurely. Also available as a 6.5-gallon primary fermentor.
