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
  • 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.

Just what I needed

I needed something for a secondary transfer container and this fit the bill. The carry strap also makes moving the jug much easier as I ferment my brews in the basement and brew on the main floor

I like them

After using glass carboys for many years and dropping two due to the weight of the glass plus fluid, I really like the thin walled lightweight Big Mouth Bubbles. Another advantage, the opening. It is wide enough for me to stick my arm in all the way to the bottom when cleaning. I would have given a 5 star if it weren't for two of the Big Mouth Bubbles I had previously bought that turned smokey at the top. Have no idea what caused that.

It doesn’t explode

I really wish this came with clips to hold the lid down. I know the harness holds the lid on but it doesn’t feel super secure. Otherwise I’m happy with it.

practical fermenter! I get to watch my beer

Pros:
- All of the BMB's come with the harnesses which cost like $13 on their own. That adds to the overall value of this fermenter. older versions without the harness had issues with the tops coming off during fermentation (especially after using starsan)
- It's clear (I've never seen my active fermentation before)
- It's much lighter than glass
- It's less prone to turning your hands into hamburger meat if it breaks
- The large mouth allows me to clean the vessel with my hands rather than a silly Q-tip esque carboy brush

Cons:
- The ribs and bubbles give bacteria more places to hide (it's probably designed for extra strength, but just an observation

All in all I like this fermenter very much and will likely purchase a 5 gallon version as well. This would have been 5 stars if there weren't so many ribs and indentations in the plastic. Again I'm not sure how much of it is for structure and how much is design but I would rather have less than more in this department for easier cleaning.
