THE EASIEST VESSEL TO GET CLEAN & KEEP CLEAN.
When you put your brew in a fermentation vessel, your ONE expectation is that it will stay clean and that your yeast will be able to eat happily without anything funky going on. A strictly non-funky fermentation party. That's it. But how can you expect the cleanest and safest fermentation environment when you can’t even scrub the bottle with your own two hands? Superior to a carboy, this vessel was designed especially for sanitizing and fermentation.

DESIGNED BY BREWERS, FOR HOMEBREWING.
Brewing can be a messy business—but no more! Stick your arm in to clean the entire inside with a swipe of the cleaning cloth. No need to use an inefficient test tube brush to reach corners and curves. Enjoy total confidence that every hint of bacteria is gone, protecting you investment in brewtime. The wide-mouth makes it easy to add or remove ingredients. The screw top guarantees the top stays on through fermentation.

Please note: The Big Mouth Harness has been designed to specifically compliment this product. For this reason we do not recommend using the Brewhauler.

Had an issue - Northern made it right! Review by Bill
Rating
I love the bottle because it's easy to clean and can easily dry hop with bags.

The way this and other bottles are made should cause you to rethink using carriers. The straps have triple or more layers crossing the center of the bottom. If the bottle does not have enough clearance it will put too much pressure on the center and pop a hole in the bottom when full of brew. As remarked by others the glass is thinner than the ones from Italy. The 6 gal Big Mouth is raised enough in the bottom center so not an issue. The 5 gal is an issue.
My resolve is to make sure I have something pliable yet firm under the bottle to redistribute the pressure evenly.
As far as the issue with the lid. I learned in my early years working on cars. Spin in the opposite direction until you feel the threads align. Then spin on. (Posted on 12/3/14)
Don't even bother with traditional carboys. Review by Jacob
Rating
This carboy is wonderful. Easy to use, clean and pour into, I could go on about the pros of this carboy, but the main reason I'm reviewing this is the fermometer you can get with this. Buy it. The trick is to cut between the lager range and the ale range, remove the big mouth bubbler sticker and place the 2 pieces of the fermometer where the bubbler sticker was.

As far as using a traditional airlock with it, I've had no problems getting the rubber stopper in the lid's twist off hole. It takes a little extra effort to twist the stopper in, but it is completely do-able. I use the 6.5 gallon carboy for primary, so blow off hoses aren't a necessity for me. If you need a blow off hose that fits go to a home improvement store and buy a vinyl hose that fits, rather than the blow off hose northern brewer sells for it. I hope this helps. (Posted on 9/27/14)
Good but not great Review by Justin
Rating
I have had this fermenter for about 8 months now, in fact, I have three of them. Overall they are great to clean but watch out for manufacturing defects. I have one that is flawless and two that have air bubbles in the glass. I made the mistake of using water that was too hot while I was cleaning one day and as it was cooling, the fermenter shattered. Be aware of the flaws that the glass may have. (Posted on 9/26/14)
Thin Glass Review by Travis
Rating
This is a good, easy to use, and easy to clean carboy, but be very careful. Don't let the thick glass around the mouth fool you, the rest of the glass is very thin. A very slight bump while washing and this carboy revealed that the glass is surprisingly fragile. (Posted on 9/13/14)
Needs a couple tweaks to be perfect Review by Andrew
Rating
Needs two things to be perfect:

1. Needs to be able to fit a standard rubber airlock seal in the hole at the top, which would also let me use a thief without opening the lid
2. Needs a flat area for a fermometer, right now there isn't a great spot to put one.

Other than that, I love this thing. The wide mouth and the ability to actually reach my hand in to clean is such a huge deal. (Posted on 8/21/14)
Great Carboy Review by Tristen
Rating
This big mouth Bubbler is very nice and so easy to work with. Cleaning is easy and stores way better than the higher carboys. The only things that I have to say that is even questionable is the thickness of the glass. Don't get me wrong, it's heavy, it just seems so lite and when I sit it on its side while cleaning it, I am a little more cautious with it. The only improvements I can see would be a better sealing system (just me, the seal is fine) and it would be great for it to have a measurement on it somewhere. I have 3 of these now and will be buying more. (Posted on 7/28/14)
Great Carboy Review by Jason
Rating
I think everything important about this product has already been said. But for clarity's sake I just want to add that you don't need an additional airlock with this carboy. It comes with a clearish plastic cap that threads onto the small center opening in the lid, and when it is put on, the lid itself becomes the airlock. Just add water to the moat, although I usually use diluted sanitizer. I've used this airlock system for many batches and it has worked fine. I have yet to practice cold crashing, so I can't speak for that instance.

For a standard 5 gallon batch, if you use a 6.5 gallon bubbler for your primary fermentation, there really isn't any need for a blowoff hose, plenty of headroom, and the built in airlock works fine.

One other thing about the bubbler that could be improved is that the glass is a little bit on the thin side. I would feel better about it if it were a little thicker, even if it cost more to produce.

Aside from that, this thing is great. Easy to clean. Fantastic! (Posted on 6/22/14)
So easy to clean Review by Heath
Rating
I have been using the 5 gal size for the secondary and the 6.5 for the primary. Have ran about 40 gallons of beer through them with no major issues. A few things I wouldn't mind upgraded though are:

A better connection for the blow off hose, so far haven't had any issue with foaming up at the lid it seems to have an adequate seal but would be nice to secure it without having to wrap some tape around it.

The foam seals are working fine once you get the lid nice and snug. Anyone know an easy way to get them out to clean them though. Takes a bit of finesse to get them out without causing damage.

Doesn't fit the stick on thermostats very well.

I just got two more in the mail today and they came with a hollow stopper that sits more securely over the hole for the airlock. Much better than the small ones that went seemed like they were going to pop out of the hole when wet. (Posted on 4/11/14)
Fantastic product! Review by James
Rating
I love my Big Mouth Bubbler. Easy to clean, easy to pour, etc...makes brewing a much more pleasurable experience. Mine came without the sealing gasket...no problem! A simple call to NB and not only did they send me a 5 pack of gaskets (I know only $0.99) but they sent me a nice hefty pint glass for my troubles. Again, not expensive items but nice touches for my troubles. Kudos NB. Look forward to future purchases. (Posted on 3/28/14)
Best investment yet Review by Jamie
Rating
I have read the other reviews and would agree this still isn't perfect but awfully close to it. The drilled cork you can order with it really doesn't fit well. The screw cap is hard to remove so it is difficult not to shake it up a little, would be nice if racking cane fit through small hole in lid. Blow off tubing fit well over small hole in cover, actually worked better than conventional carboy that way. So easy to clean old carboys are for sale if anyone wants them. (Posted on 3/25/14)
