Product Details

The Siphonless Big Mouth Bubbler® Plastic isn’t just easier to use. It’s better for your beer. Fight oxidation and contamination by keeping your fermentor closed for transfers. Never open the lid to insert an auto-siphon, just turn a valve and you’re set. Best of all, you’ll have clearer beer. Gently rack liquid from the spout into secondary without disturbing the trub.

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.

Make your brew day easier and your beer better with the siphonless Big Mouth Bubbler®.

Includes:

  • Ported Big Mouth Bubbler® Plastic Fermentor
  • Spigot
  • Single Port Universal Lid


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

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

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.


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.

Nice Fermenter – Terrible Lid
Two days ago, I used two Big Mouth Bubblers for as primary fermenters. I could not the universal lid to stay on. Finally after some web searches, I found the suggestion to turn the silicon ring around, so the wider part goes into the hole first. It’s hard to jam the lid in, but it now seals. I know this is the new, universal lid and several people had problems with the old lid design. They are great buckets, I wish the company would get the lid to seal correctly. I will not recommend the Big Mouth Bubbler to anyone until the lid is redesigned. On a positive note, Northern did a great job with customer service when I placed the order!

I liked the screw top better
I like the siphonless big mouth bubblers better than buckets because I can watch the process my beer is going through and then I can use the spigot to rack for my next step. The one thing that I would prefer is the screw on lid rather than the press on universal lid because they keep popping up out of the bubbler and I've had to tape them down to keep them air tight.

great fermentor but horrible lid
just brewed today and placed my stout into my fermentor for the first time loved the gallon markings and the spigot at the bottom. Was loving everything about it until i placed the lid on it and it immediately popped off. After multiple times of trying to get it to stay on I finally had to tape it in place hopping i didn't contaminate my beer. Hate the fact that now I'm going to have to constantly monitor the lid and hope my beer doesn't go bad.

Great sihponless Big Mouth Bubbler
I have the 6.5 gallon original Big Mouth Bubbler and love it. However, I wanted to try the siphonless version, and needed a 5 Gallon for secondary anyway.Wow, I really like being able to transfer my fermented beer to bottles or kegs without disturbing the trub. It works fantastic. Cleans up just as easy as the non-ported version.Oh, and if you want room for your 5 gallon batch primary fermentation, purchase the 6.5 gallon version.

Worth the money, but secure the lid down
The overall design of this fermenter is great. It is lightweight, easy to handle, resistant to breaking/shattering, accessible, quick to clean, and efficient to use. The lid still remains in need of improvement. Getting the lid to remain down can be a hassle. My last brew I ended up tying a string to the carrying straps or using tape after finding the lid popped out and exposing my beer. Overall I love these fermenters and have transitioned away from glass, but the lid requires a little extra attention to avoid causing concern.

Popping lid is a total dissapointment
Positives:The carboy is pretty sturdy for plastic, super light, the level indicators are great to have and the spigot has not leaked.Negatives:Active fermentation (even non vigorous) causes the lid to pop off; plain and simple. Interim solution: duct tape. In any case, we should not have to hack or babysit the lid for the price and claim of quality of this product. Also TIP: if you don't dry off the rubber gasket and surface on the carboy the lid will not even stay in at all.This lid issue can easily been solved by combining the old screw lid with the updated gasket design. I'm not sure why this wasn't the intent in the V2 lib design. In fact, if googled, someone has already solved it exactly that way. Unfortunately, the older lids are no longer available for purchase.Had there not been this silly gasket issue I would EASILY rated this a 5 star product.

John,

Thank you for taking the time to write a review. This is something that we are working towards fixing. I have also had success with turning the silicone gasket upside down.

Cheers!

Spigot has a crack and leaks
I'm all set for my first time using this fermentor and have found that the spigot has a crack and leaks as a result. I'm so thankful I found this problem with water before I loaded it up with beer. I'll be contacting customer service first thing tomorrow morning and am hoping to have a good experience.
April 25, 2016
Response from Northern Brewer
Sorry to hear about that issue! Customer service will be contacting you to make sure we get you fixed up to the best of our ability. It is always a good idea to leak test before filling so glad to hear you caught the issue before it was a disaster. Cheers!

This fermenter leaks!
Purchased this 5 gal Big Mouth with siphon tap a couple of months ago. I had high hopes for it. However the unit as received leaks at the bottom of the siphon. I carefully tried to hand tighten but beer still will leak around the edges of the siphon. The siphon washers as supplied do not prevent the beer from getting from the inside to outside. The leak is a very very small trickle but you can actually see the beer getting thru the washers. I believe because the plastic fermenter has thin walls that the siphon cannot seal properly. Not a good thing.

Overall it's good. Lid needs some work.
I like the Big Mouth bubbler. easy to clean, like the spout. The lid....the darn thing didn't want to stay on. I contacted Northern Brewer and they told me to turn the rubber gasket upside down and that seemed to do the trick. Just wish that Perhaps the lids should come that way.

Good idea
I bought the big mouth carboy because I figured it would be easier to clean than a regular carboy, and this proved to be true. Since you can get your hand down into it, it is easier to clean, and it works fine as a fermentor. I gave it 4 stars for two reasons, one, it is hard to move, hard to grab a hold of and carry. This is usually not a problem for me but because of unexpected circumstances, I had to move my fermenting wort from one location to another. The 6.5 gallon ale bucket that I was using for another batch was considerably easier to move. The second reason really wasn't it's fault. The spigot that I got did not seal properly so I has a slow leak, discovered after I put a batch in there. Luckily I was only going to have it in there for a little over a week, and it was a slow leak so I only lost about 12 ozs. Since this is the 5 gallon size, it really wouldn't work for a primary fermentor, but it is a good secondary (I replaced the spigot the second time I used it). Overall a good choice

What size tubing does the spigot accommodate?
K P on Nov 5, 2015
BEST ANSWER: The same as the bottling bucket I believe it 3/8" internal diameter
I lost one of the two rubber washers at the spigot fitting. Is it possible to buy a replacement one?
S M on Apr 26, 2016
BEST ANSWER: Sorry, because of the cost of such small, plastic items, we only have new spigots for sale. Not sure if there are alternative sources for a similar sized gasket out there. Sorry I do not have the answer at this time. Feel free to contact customer service.
What material is it made of ?
F R on Nov 8, 2015
BEST ANSWER: Hey Fred

This particular bubbler is plastic.
Newbie question: If I use this as the secondary fermentor, can it pull double-duty as a bottling "bucket" since the trub is below the spigot? I'm currently using NB's fermentor bucket and bottling bucket.
F R on Oct 15, 2015
BEST ANSWER: That should work just fine IF you are using carbonation drops directly into your bottles. But if you are using a priming solution, you will be stirring up all of the remaining trub with the beer to be bottled. That wouldn?t be ideal. I really like using these siphonless fermentors, but I still prefer to use my bottling bucket because I can attach a dip tube in it to get every last drop into my bottles.
Is there any hint of a plasticy smell or taste, even for very light bodied beers?
R E on Sep 14, 2016
BEST ANSWER: I have used mine on several light bodied beers and have not noticed any plasticy smell or taste. One thing I did learn though is that if you put any additives in at re-rack they can get stuck in the spigot. I had that happen with some vanilla beans I added to a stout. Some smaller pieces got stuck during bottling and was difficult getting them out.
Can I use this as a secondary fermentor for 5 gallon batches? Sorry for a dumb question but I'm a newbie
Brad B on Dec 29, 2016
BEST ANSWER: I use Siphonless Big Mouth Bubbler's for both primary and secondary. I do exclusively extract kits and would highly recommend using 6 gallon for primary and 5 gallon for secondary. This has worked for me and I learned the hard way that using a 5 gallon bubbler for primary is a risk not worth taking. I started 2 years ago and have made over 30 batches and this seems to work just fine.

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.
Is the 5 gallon big mouth bubbler big enough to ferment a 5 gallon batch of beer?
A shopper on Dec 13, 2016
BEST ANSWER: Yes, but I recommend you use a 6 gallon for primary fermentation and a 5 gallon for secondary. After primary fermentation you are going to have a bunch of sediment on the bottom so it's usually a good idea to use a bit more than 5 gallons to start if you want to end up with a full 5 gallon batch when it's time to bottle or keg.
Does the spigot have any metal on/in it? I want to use this for kombucha but it can't have metal on it.
S G on Oct 15, 2015
BEST ANSWER: There is no metal in the spigot or anywhere else in this fermenter. I am now in secondary fermentation using the 5 gallon and used the spigot & some tubing to transfer my brew. Very easy.
Does the harness still work on this model? Seems like the port on the side sits exactly where the harness strap normally goes
A shopper on May 15, 2017
BEST ANSWER: Yes the harness will fit if you start by getting the harness over the port first, then move over to the other side and firmly pull the strap over the other end of the bottom. It may seem a little tight, but I always put the harness on the spout end first before racking any wort into the fermentor.
I would think we would need to sanitize the spigot when transferring beer to 2nd fermentor or bottling bucket? Or is it not necessary?
E D on Jun 2, 2016
BEST ANSWER: yes you should always sanitize everything. When Sanitizing the Big Mouth before you add the beer just open up the spigot and let it run. Then when transferring to secondary or keg I spray the outside and up into the spigot as much as I can with Starsan. Sanitize the tubing and the vessel you are transferring to and you are good to go
Is this BPA free plastic?
P J on Feb 29, 2016
BEST ANSWER: Lightweight PET made in America is free of BPA or any other contaminants. Cheers!
I'm seeing a lot of comments about secondary fermentation, but I'm not that advanced! Can this fermenter be used for regular fermentation?
April A on Nov 23, 2016
BEST ANSWER: Not for 5-gallon batches, you need headspace to contain the krausen (foam). You could use this as a fermenter for a 3 or 3.5 gallon batch.
I just purchased one of these. The hole in the vessel for the spigot is heat cored. The melted plastic at the edge of the hole on the inside and outside made a small (0.5 mm?) ridge that made it hard to get a seal. Should this material not have been trimmed at the factory to ensure a smooth surface for contact with the rubber washers? Did anyone else have this issue, and how did you resolve it?
R H on Dec 8, 2015
BEST ANSWER: Hi Glenn

It sounds like you've got a defective one. Do you think you can reach out to us directly either by calling 1-800-681-2739 or by emailing brewmaster@northernbrewer.com? We should be able to get you fixed up. Calling might be best but either will work

Gabe from NB
What are the dimensions?
Sam K on Aug 13, 2015
BEST ANSWER: The 5 gallon is 10" in diameter and 22" tall with the lid on. The lip opening is 5.5" wide and the spigot has a 3/8" OD barb so get 3/8" ID tubing.
I have been thinking about ordering the new Depth Charge for the Big Mouth Bubbler - looks like a great product. Will the Depth Charge work for the ported 5 gallon Big Mouth Bubbler?
