Product details

Big Mouth Bubbler® Plastic fermenters are virtually indestructible fermenters, 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.

Now Includes the Big Mouth Bubbler® Carrying Harness for lifting, transporting and ensuring your Big Mouth Bubbler lid stays firmly in place during even the most intense fermentations.

Included: 

  • Big Mouth Bubbler® - 6.5 Gallon Plastic Fermenter
  • New Big Mouth Bubbler® Universal Lid
  • Carrying Harness for Big Mouth Bubblers®

Required but not included:

Superior to a carboy, 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.

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.

The new Big Mouth Bubbler® Universal Lid fits all Big Mouth Bubbler® Fermenters. 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. Removable ribbed silicone ring ensures 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 fermenter.

Lid port works with our Small Universal Stopper or a standard 6.5 rubber stopper.

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

Harness is king!

Can’t believe I haven’t gotten a harness sooner for these things. Makes life way more easy!

Big mouth bubbler

The shape of the container is good for up to a 5-gallon batch, with headspace for krausen and foaming. The wide mouth helps with cleaning, holding a wide-mouth funnel and adding yeast. The cap seals well (with a bubbler inserted in the central hole). The plastic construction is good for minimizing weight and seems strong enough to stand up to use. When you begin using it, it becomes obvious why the harness is needed. However the assembled, loaded container is still pretty awkward to move.

Good--except for the lid

I love the bubbler, but I wish I would have read the reviews more closely before I bought it. My lid pops off just like everyone else's. I think the trick where you flip the seal upside down will work, but I'll find out for sure the next time I use it. I just don't understand why Northern Brewer would stick with a poor design when the fix is so easy. Just go back to the screw-on lids.
