Product details

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.

Included: Big Mouth Bubbler® - 6.5 Gallon Plastic Fermentor, single-port universal lid.

Required: Small Universal Stopper & airlock. Configure options above.

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

Big Mouth Bubbler® - 6.5 Gallon Plastic Fermentor

This fermentor does the job and is easy to clean. However, the lid does not stay on during fermentation. I had to use duct tape or a cement ring to keep the lids on! It is annoying

Works great, this is the 4th bubbler I have purchased from Northern Brewer.

Good concept, inconsistent sealing

The first time it sealed with no issues, second go around I wasn’t able to get the lid to stay seated. The pressure kept popping it up. I reached out and they were very helpful and gave some tips that may help, but somewhat of an inconvenient system when you can’t fully tell if it’s going to stay sealed or not. The company seems great, but this specific product I haven’t been completely sold on (maybe that will change with future use?)

Big Mouth Bubbler® - 6.5 Gallon Plastic Fermentor

I really enjoy it... much easier to deal with than glass... and the hop depth charge lid (sold separately) makes dry hopping a breeze... one issue with the lid which doesn't always like to stay on if it is wet

Wish the top was a **** on. Had the top unseal on one batch so I just have to weight it down now
