* Required Fields

Price as configured: $0.00



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. Equipped with a taller body and smaller footprint, Big Mouth Plastic is ultra-storeable, fitting easily inside a standard bucket to take up less precious brewing space. 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. And, of course, its revolutionary wide mouth eliminates glugging and enables hands-on cleaning for a faster, cleaner clean. Finally, get your hands wet.

The new Big Mouth Universal Lid (included) fits all Big Mouth Bubbler® Fermentors, and has ribbed silicone rings ensure a completely air-tight seal. 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.

Follow Up
I have only one complaint about this product. There are three rings that are dimpled to look like bubbles. These dimples are on the outside as well as inside the Big Mouth. When cleaning you need to make sure you get into those dimples with your rag or sponge. If the insides were completely smooth cleaning would be easier. Otherwise this is my new favorite fermenter and I'll probably order another soon.

Good but hard to move
I really like the design and price, but it's hard to pickup and move and because it's plastic if you squeeze the middle it can push liquid out the top. Overall though it's good, just need to order the strap carrier

6.5 gallon plastic big mouth
Received two of these plastic containers and very happy on first visual check._x000D__x000D_Made a batch that first weekend and plenty of room that I did not have to worry about a blow off tube. Transfer to secondary (also a plastic big mount). Works great, been waiting for this product to finally come out. Glad I picked it up._x000D__x000D_Worth every penny and no broken glass and missing toes to worry about!!!!

Great addition
It works great for a 5 gallon batch with the S airlock, no blowout, highly recommended!

Nice but could be better
I have now used this for one batch. I like it because you can easily see what is going on. It was very nice to see that even though in reality meant nothing to me. The lid is much easier than the 6.5 bucket. It is not quite as easy to clean as a bucket but still easy. The main drawback I have is how freaking cheap the plastic is. It feels flimsy. I would have gladly paid another $5-$10 to have it made out of more substantial plastic

Love it
Getting ready to order my second BBB, think it is much easier to keep clean vs plastic pails (and doesn't stain or develop scratches that hide nasties)._x000D__x000D_Some of the other reviewers mention some drawbacks such as the lack of a gasket seal or difficult to pick up without squeezing the seemingly flimsy plastic carboy in; but I feel these are minor as it has turned out to be more durable than I expected when I ordered the first one to test and it doesn't seem flimsy to me at all._x000D__x000D_I don't see myself using the pails for anything other than soaking bottles from now on, plus it does take up a bit less floor space in my already too small kitchen!

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 size cork/stopper does this take?
A shopper on Mar 17, 2017
BEST ANSWER: These carboys will take a "small universal stopper" ( SKU 7081 ) or a #6.5 stopper ( SKU SD65 ). -Mike W, Midwest Supplies
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.
