Meet the Big Mouth Bubbler®. The revolutionary replacement for those water jugs known as carboys.
Its mouth welcomes cleaning and facilitates a sterile fermentation environment. No bung slipping on a foamy carboy top—the Big Mouth cap is a twist off. Once you screw the cap on, ITS ON and not coming off until you say so.

The Big Mouth Bubbler includes a drilled stopper and a microfiber cleaning cloth.

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? This vessel was designed especially for sanitizing and fermentation.

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.

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.

Great for fermenting, but be careful handling it Review by TimM from Huntsville

(Posted on 9/13/14)

Product Rating:

I really enjoyed this for the short time I had it. Yes, there are some problems with the lid and airlock. You have to screw the lid really tight to get it to seal. And the water evaporates fast out of the wide airlock. Also, had I owned it longer, I'm sure I would have needed to replace the seal, so get some replacements to have on hand.

But... The main advice I have is to be VERY careful handling it, as it will break fairly easily -- much more so, I think, than a regular carboy. When lifting it onto the kitchen counter, I barely tapped the bottom part of the side to the edge of the granite countertop, and CRACK! the sound was unmistakable. It left a hole in the jug, and shattered pieces of glass on the counter. Luckily, it was empty!

Worth the money Review by Ted

This is what I've been waiting for. Easy to clean, great for dry hopping, adding oak chips, or fruit. The price is reasonable and the fermenter looks strong.

Great Item!! Review by DirtyJerzBrewer

I have to say this fermenter is great. I love the design. Easy to clean, easy to add things to your beer ie. wood chunks, fruit, hops, etc. I picked up a extra pack of seals when ordering, so I had some on hand for the future. The lid doubles as an airlock which is a very cool feature. I still use a regular airlock with a stopper.

The BrewHauler works perfectly with this (I have the 5 gal model). It was one of the first things I check after receiving this in the mail. It fits like a glove. No need to purchase the $20 one they are selling.

I will most likely be purchasing more of these, as needed.

Pleased with it Review by Simon

I got it during the holidays, and it gets constant use. It easy to clean and I can see it replacing my car boys. The top and air lock hole could be improved though.

Great features except built in airlock. Review by Chelsea

(Posted on 3/9/14)

Product Rating:

All the other reviews are spot on: this by far makes adding ingredients, racking, and cleaning much much easier. However, the plastic lid needs some work.

First, the plastic is thin and has already cracked at the neck of the airlock. The lid needs to be made of thicker/sturdier plastic.

Second, the built in airlock that comes standard with the 5 gallon is worthless. You attach a cap to the neck and fill the whole top of the lid (shaped like a bowl) with liquid to create the airlock. There is a lot of surface area exposed to the air and my sterile liquid evaporated within a day, thus defeating the airlock. A size 5.5 drilled rubber stopper is required to attach a real S-type airlock, but doesn't come with the package (despite the picture).

Third, the comments about the "gasket" are spot on: it's just a very thin piece of foam paper that doesn't seal unless you really twist hard to seat the lid, at which point the thin plastic becomes a concern.

All-in-all a great idea for a product with good execution, but a little more work on the lid and airlock design would make this outstanding.

Easy to use Review by Mike

bought one of these to use for aging and dry hopping. I was surprised how easy it was to use, hoping to replace all of my carboys over the next couple years with these and the 6.5 gallon version.

Great for Kombucha! Review by chris

(Posted on 3/3/14)

Product Rating:

I am using this to brew Kombucha and it is fantastic! I use it without the screw top since Kombucha needs air to breath. The micro cloth that comes with it makes a wonderful air filter to place over the wide mouth while my Kombucha is brewing. I could not be happier with this product.

Evolutionary Review by Orson

I have two in use now. Good size and easy to clean and I can reuse my brew hauler. The gaskets aren't good enough, and I had to triple them up. The lid should be made stronger so it doesn't crack. A good design that can become great, with a better lid & gasket.

Nice but... Review by BrewGuy

(Posted on 2/24/14)

Product Rating:

I like the product. It has a wide mouth as advertised, and appears like it will become really useful. I am disappointed on two points, however:
1. The lid is a flimsy, thin plastic. I was really expecting something a little more solid. I can already see into the future - accidental crossthread = cracked lid or destroyed threads.
2. This thing does not come with a gasket to seal the lid! There is a gasket kit that offers replacement gaskets but I did not order that for now thinking that certainly the product would come with a gasket and be ready to use. So, now I need to order some gaskets and wait on insanely slow shipping again before I can use my new carboy. Not to mention pay for more shipping. So, there is my review.
In summary, good product, be careful with the lid, order gaskets because it does not come ready to use out of the box.
