The fermentor that started it all, reinvented again! We’ve taken the revolutionary Big Mouth Bubbler® glass and re-engineered it with the help of world-class Polish master glassmakers to ensure sturdy, solid, superior craftsmanship.

Extra-thick glass eliminates oxygen permeation and keeps your brew safe. Banish bugs and bacteria with perfectly air-tight seals from a carefully ground, completely smooth and obsessively flat neck top.

In the evolution of Big Mouth Bubbler®, we’ve added some perks! Instantly measure volume with gallon graduation marks. Easier transfer of clear beer with a taller, narrower body while ensuring less liquid is left behind.


Caution: Big Mouth Bubbler® is a large hand-formed glass item that can be easily damaged if not used with proper care and handling. It may have variations in shape and thickness, and will show the normal bubbling characteristics of hand-formed glass. Extreme changes in temperature or sudden contact with hard surfaces may cause glass to crack. Handle with care–we strongly recommend using the Big Mouth Bubbler® carrying harness for increased safety and ease of handling.

Product Details

Bid your funnel and siphon sayonara! Pour cooled wort directly from your kettle into the Big Mouth Bubbler® for instant transfers. Pitch yeast without it running down the sides of your fermentor. Easily add flavorings to secondary, and then just as easily remove them!

Gallon graduation markings help ensure precise measurement of fermenter volume.

Last but not least, you asked and we listened—more space for the adhesive FermagraF° LCD thermometer than any other glass fermentor! The most obsessively engineered glass fermentor ever created—we are proud and excited to introduce the new and improved Big Mouth Bubbler® EVO 2.

Note: We still strongly recommend the Big Mouth Bubbler® carrying harness.

Each Big Mouth Bubbler® Includes:

  • Big Mouth Bubbler® Glass Fermentor, Universal Lid*
  • Big Mouth Bubbler® Microfiber Cleaning Cloth

*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.

You will also need a Small Universal Carboy Bung - drilled or solid.

*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.

Heads UP
Very beautiful. My wife wants more of them around the house for pickling and the like.

HEADS UP though, the 5 gallon version has NO head space at 5 gallons, which means it's not that great for a primary fermenter but would be great as a secondary.

Order was not correct
The fermentor was fine. The problem is that the lid does not stay seated and the loc stopper sent was too small. I had to tape the lid on with duct tape. Not much of a seal

Response from Northern Brewer
Hi Ed, we'd be happy to address any problems you may have with your big mouth bubbler if you would like to call or email us.

Top comes off all the time, used duct tape to keep it on. Would not recommend. If they had a screw on style top like plastic version, would be much happier

Kid could be better
The big mouth bubbler is great, but the universal lid does not seal well.

Easy to use, Questionable workmanship
As you could imagine, its easy to use and functional. I was concerned about mine when I got it because the top opening was out of round. Since these are hand made or hand blown, the opening was really rough, and not round. I almost sent it back, but the lid compensated for the imperfection. I have the 5 gallon and use it for a secondary. I wouldn't try to use it for a primary.

Lid insight
I agree with most of the statements here about the lid, however, I just discovered that the Little Big Mouth Bubbler (1 gal) lid fits the 6.5 gal BMB EVO2 screw threads. Perhaps NB can make just the LBMB 1 gal lids available.

The only flaw with this product is that the top keeps popping off during rapid fermentation. I've only used it once so far for my "Heady Topper" clone I made, and maybe it was because of the large Krausen it made but it would be a better design if the top screwed on somehow rather than just being pushed in snugly. I ended up just laying a few bricks on the top until fermentation subsided and the krausen settled.

Solid!
Very well made. Strap is a must if you are carrying it any distance or are putting it up on a shelf.

Big Mouth Rocks
This thing is very heavy and it really is solid. I really really really recommend getting the harness. I'm not clumsy but I really don't want to ever drop this badboy. Great product!

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.
Has the lid issue been resolved? I have no Big Mouth products so not sure if the universal lid is the issue or the solution.
A D on Nov 23, 2015
BEST ANSWER: I purchased this for my son. I asked him this. Here is his response:

"I did notice the first time I used it that when the beer fermented, that the bubbles came both out the top of the lid and the sides of the lid... The second time I brewed I didn't fill it quite as high and haven't had any problems"
where are the 5 and 6 gal marks on the carboy? I am assuming that the 5 gal mark is at the base of the neck when it finishes tapering off?
A S on Jun 27, 2016
BEST ANSWER: Yes the 5 gallon hash is right at the base of the neck where the bubbler bigins to flare. Little to no breathing space for primary but great for secondary.
Any chance the lid issue will ever be resolved? This is kinda ridiculous - after using star San to sanitize, without anything in the big mouth bubbler the lid pops off... I've gone through an entire roll of electricians tape in two days while fermenting, retaping 3 times.
This is useless for fermenting, worst vessel I've ever used, too bad- made by Brewers for Brewers?
A D on Mar 28, 2016
BEST ANSWER: Contact customer service if experiencing an issue with a product. Quit wasting tape, maybe try a weight to hold it down. Contact customer service to get help to see if we can advise on use or find out if its just a defective unit. I tried but could not find any orders under your information but we are happy to help, give us a call! Cheers.
Is the bottom flat like a flask so a stir bar won't fly off? Thanks.
R I on Sep 7, 2016
BEST ANSWER: If the stir plate motor and magnet are strong enough, it will work. You can see a demonstration in this video, at the 1:10 mark:
