Standard Shipping Rates Apply to this product
Superior to a carboy, the 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.

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.

Included: Big Mouth Bubbler® - 5 Gallon Plastic Fermentor, single-port universal lid.
Required: Small Universal Stopper & airlock. Configure options below.

Product Details

Superior to a carboy, the 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. Best of all, it will not shatter when dropped or knocked. 

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.

The optional Dual Port Lid allows for the use of a temperature controller probe. The ThermoStar Dual-Mode Digital Temperature Controller with optional 12" stainless probe ensures precise and repeatable fermentation temperatures!

Lid ports work with our Small Universal Stopper or a standard 6.5 rubber stopper.


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

Note: We recommend a soft cloth for cleaning the inside. Standard carboy brushes will scratch plastic fermenters leaving places for grime to hide. A warm cleaning solution will suffice. Do not use hot water on plastic fermenters of any sort. The Big Mouth Bubbler® is compatible with a standard carboy dryer when the dryer is used inverted.

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

5 gallon fermenters are best for the secondary conditioning stage of beer fermentation. The smaller size eliminates extra airspace in the fermenter reducing the chances of oxidation which can stale the beer prematurely. Also available as a 6.5-gallon primary fermentor.

Big mouth bubbler babay!
I bought this fermenter to replace my carboys. Very pleased with my purchase. Easy to fill and dry hop. Easy to clean and I'm yet to have any of the lid issues. I dry the opening before adding my sanitized lid. No pop offs so far.

The Lid Works Fine
It's very important that you take a few seconds and carefully DRY the silicone seal, and the inside rim of your plastic carboy with a paper towel, and THEN this newfangled lid design works just fine. Knowing that, i get a great seal (better than the screw top), and I like this fermenter. I like glass, too... but when it's time to lug things up from the basement, this is a lot easier.

Despite following NB's instructions (turn the plastic seal upside down, place on container when dry) the lid does not stay sealed. I had to put a large brick on top to keep it from being pushed up and out by the fermentation. The container works fine, but not the lid. Whoever makes this product--FIX IT CORRECTLY.

It's plastic, light and easy to clean but the lid don't seal
The quality of it is there but the inner fitting lid design isn't the best. Once you rinse and sanitize with star san the gasket on the lid won't make a complete seal and it wants to lift out of the opening on its own. Not the biggest deal for fermenting but it's a bummer for sencondary use.

The lid pops out
I have researched online and supposedly the lid does pop out due to it's universality. It makes me uncomfortable. I wish I could buy a specific lid for each of my big mouth bubblers.

Good for open air fermentation...
New plunger style lid will not stay sealed - wet or dry.

Response from Northern Brewer
Thank you for contacting us. As with fermentor buckets, when there is that much pressure pushing up and out the lids can sometimes come off. The lid coming off won't harm your beer since there is so much CO2 off-gassing during primary. The nice thing about the lid coming off is that the pressure is escaping instead of building to a point where the fermentor could shatter. If you are wanting to keep the lid down however leaving something heavy on top or taping it down should help. As fermentation settles down though there will be less pressure pushing on the lid. If you still have any more questions or concerns I am just an email away.

Big Mouth Bubbler 5 Gal
I bought this one to replace my 6 gal, whose bottom cracked for no reason (while soaking, sitting on a rubber anti-fatigue mat; came back and the water was down about a third, then noticed the crack as I dumped it. But this is a review of the replacement). I like it for the same reasons I liked my 6: the big mouth allows me to dry hop or add a hop bag of cacao nibs and PB2 for my PB Cup Porter, to keep things less sludgey in the carboy. As I recall reading in the description, the 5 gal is good for secondary, which is what I use it for; it wouldn't have the headroom for a hearty primary fermentation. I have to agree with others, though, that the new lid is a problem. I tried it out, and it slowly popped up as the pressure increased; I had to replace it mid-secondary with the old top and ring from my deceased 6-gal. They need to correct this quickly, or it would be a deal breaker for any new purchases. I think if they combined the new design with those gaskets, sized it to fit such that the ring would fit over it and screw down around it like the old one, and that would resolve both the air leakage of the old cap, as well as the 'creepage' of the new cap. (IMHO)

Big mouth bubbler is a must have
The big mouth bubbler is a great secondary fermenter I plan on getting a 6 gallon to replace the bucket fermenter that came with my kit
August 17, 2016
Suggested improvements
Wide neck should make for easy cleaning but, overall, the bubbler is pretty awkward to handle. 1- It is too tall. Better if it was shorter and wider, like standard 5-gallon carboy (neck width is OK). 2- For efficient draining and rinsing, the white plastic top piece should be domed, not flat and it should have a longer neck (about 2 inches). As it is, it cannot be used with a standard squirt type bottle washer because the base is in the way.

BEST ANSWER: Yes, the Big Mouth Bubbler Plastic does have indentations as markings but does not have numbers 1 - 5 or .
You have to count them to determine at what level you are at.
How can I seal the lid? It keeps popping up.
A shopper on Feb 1, 2017
BEST ANSWER: There are a few tricks that can help get you bubbling away happily.

First, I would sanitize the lid and let it air dry a bit before inserting. Press one side of the lid in first, then the opposing side. Lift up the lid in places until you see and feel the ribs on the lid gasket "lock" into place. It should feel noticeably tight once you do so.

If a tight fit is not attainable with the normal insertion technique above, you're still in luck. Remove the lid, take the gasket off, and reinstall the gasket upside down. The ribs on the gasket will engage in a much tighter manner. You'll still want to install it according to the above instructions, but I think you'll find that it grabs much more.
I have the new style "push down lid". It will not stay on "sealed". I read online that someone suggested taking the screw down component and shaving down the lip of the new lid to make a hybrid as the new lids don't stay on. Please sell the screw down pieces so we can make this modification
Tim L on Aug 30, 2016
BEST ANSWER: We do not yet have those style lids available for sale, but we are looking at this and several other options for improving the seal of these lids. Hopefully we will have something soon for you.
Does this product for $29.99 come with a lid and airlock? A lid is shown in the image, but I can't tell by the product details. Thanks!
C H on Jan 14, 2016
BEST ANSWER: Hi Charlotte,

It comes with the lid, but the stopper and air lock come separately. The stopper that fits is:

And the air lock options are:

Hope that helps!

I am downsizing from 5 gallon to 2.5 3 gallon because I am retired and live by myself . Since I am, how will this work out for me? Thanks
L A on Oct 1, 2015
BEST ANSWER: Well

if you are making beer

it should work well still

just not for long term storage (3+ months) of a beer product. If you are doing simple 1-

week primaries with optional 1-

weeks secondaries

the larger vessel could still work well. I routinely start a

gallon batch in a 5 or 6 gallon wide mouth fermentor

and I usually secondary in a

gallon carboy

but I have secondaried in 5 gallons before and it works fine. I just would not let it go for very long. I hope this helps explain what situations it works well for!
How do you seal the lid? If it does not seal, can you send me one that does? Or should I return it?

Can you get a solid water tight lid?
N H on Jan 22, 2016
BEST ANSWER: We're continually working to improve the Big Mouth Bubblers. However, the universal lid will seal well.
