Purpose-designed from head to toe, Big Mouth Plastic features improved strength and durability through a decreased base diameter, punted bottom and 3” thick anti-flex ribs.

Constructed from food-grade PET, Big Mouth Plastic features gallon graduation marks for instant volume measurement, plus a punted bottom to efficiently settle out yeast and promote crystal-clear finished fermentations.

Upgrade to a dual-port lid plate for continuous thermowell monitoring in one port to sustain constant ideal fermentation temperatures and take gravity readings without ever removing the lid.

Earth-conscious design. We have thoroughly planned out every last feature of this innovative product, right down to it’s physical construction. After untold amounts of research into the properties of PET plastic, we fanatically chose to make the Big Mouth Bubbler™ with as little plastic as possible while still maintaining a high degree of structural integrity and brute strength. What does this all mean? It means that the impact to our planet Earth is as minimal as possible. We call this a win-win situation. Check out the Plastic Big Mouth Bubbler™ for yourself. You will never go back to a traditional style carboy again.

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

You will also need a Small Universal Carboy Bung (not Included) - drilled or solid.

The Carboy Dryer is compatible with the Big Mouth Bubbler® when used in an inverted position.

Worked Great - Until it Failed
I purchased my 6.5 gallon plastic Big Mouth Bubbler back in June of 2014. I've been using it as my primary ever since. I've had great success using it for this purpose, until this last brew day.Made a very nice DIPA and filled BMB to 5.5 gallons. While placing into my fermentation chamber (chest freezer), the plastic failed and a large crack ran from the bottom edge 1/2 way up the side. As you can imagine, this was a big loss and very messy. Entire batch (just after pitch) went spilling into my freezer (good thing as it would have spilled out onto the floor otherwise). An extra 2 hours of cleaning followed... oh joy. Lost a batch and even more cleaning than normal. Lovely.While it was nearly 2 years old, it was used as intended and was cared for properly from the start, so it shouldn't have failed. I'm over these thin plastic fermenters. While it was nice to have a light weight fermenter, it isn't worth the potential loss. Very disappointed.

Lid Seal ISsues
The Big Mouth Bubbler fermentor has a really difficult time keeping the lid on. The lid just pops off, I tried wiping with paper towels on the lid and the gasket, but it continues to press out of the mouth. I got a bungee cord and 2 gallon jugs, one on each side, and strapped the lid down, and it has stayed since. This will not be able to be used as a primary fermentor, the risk of blow off on an active fermentation is too great.

Still has lid issue.
Just put my first batch into this, and really like the overall size as well as the "Big Mouth". But the lid just pops off within 30 seconds. I tried every method I could think of to seat the seal rings into the opening, but it always worked its way off. Finally had to tie it down. If I had time, I would have cleaned out one of my older fermentors and just transferred the batch over. I've not seen this problem in 20 years of brewing, and I won't be using this fermentor again.

Worked Great
So much easier to clean than a glass carboy. I would recommend this product to anyone. Plus it's cool to see what's going on during fermentation.

Big Mouth Bubbler
Used it to make 5 gallons of hard cider. Easy to clean with the wide mouth, seals well and the clear container makes it easy to monitor progress.

Just got mine a few days ago and I already have a batch of beer fermenting in it. It's sturdy and stays fairly rigid with five gallons of beer in it. The lid is tight fitting and secure. A universal bung will fit in the port in the lid. Even wet it stayed in there. Cleaning this should be a breeze.

Great Addition!
This is a must have addition to anyone's set up. Easy to clean, lighter than normal glass carboys, and allows for more of a visual timeline compared to a conventional bucket.

6.5 Gallon Plastic Big Mouth Bubbler
I am a traditionalist. However I did give the PLASTIC Big mouth a try. I have finished my first batch and in bottles and sampled. I am very happy with my outcome. No off tastes at all. In fact I can say that the flavor of my batch is very sharp and clean. I am writing this review because tonight I am getting a second one. There are all the obvious positives of light weight and cleaning is a breeze.

Are they BPA and or BPS free?

Does the big mouth bubbler have a gasket for the lid?
A shopper on Feb 9, 2017
BEST ANSWER: No, there is no gasket included for the lid. It does loosen a slight bit during fermentation, which causes the airlock to lose pressure, but the brew continues just fine. I tighten the lid every other day and it pressurizes the airlock fine.
What are the outside dimensions?
K S on Aug 9, 2016
BEST ANSWER: They are about 11" in diameter and about 22" tall (without the airlock).
Can you place it inside a standard fermenting bucket to move it around when full, instead of the specialty designed strap.
D B on Apr 1, 2016
BEST ANSWER: This is not recommended. The Big Mouth Bubbler is slightly too wide to fit wholly inside the bucket.
