Glass is Excellent, Lid Seal is Not
I love these glass jars. They are very sturdy and the wide mouth makes them easy to clean (you can just run them through the dishwasher). Unfortunately the seal in the lid is made out of some kind of paper/styrofoam which absorbs smells, so once you make kimchi in this jar, the lid seal will forever smell like garlic. Please make a silicone seal replacement! Or even sell alternative lids, because these are solid, nice glass jars otherwise.

a great product!
This is a well made little fermenter. Great for experimental test recipes or for just a small batch of something. I have a green tea/Craisins® batch working in it right now.

A suggestion: a TWO gallon size, in the same quality and diameter, ALSO would be a great idea!

Perfect for 1 gallon batches. I prefer to brew often, though I brew 5, 3, and 2 gallon batches as well. There is plenty of head space...I did not even consider a blow-off tube. I am ordering some more for my primaries and using my jugs as secondaries.

Plenty of head space for a one gallon batch. I did not need a blowoff tube.

Nice Glass!
I figured that this vessel would be 'neat', but I wasn't prepared to be so impressed with the product.
Immediately upon unpacking, I could tell that this is a far cry from the flint glass jug which I was planning on using before.
The fit and finish is very good, the lid and gasket are perfect.
I see this little jug being in my arsenal for a long time.
Thx. Rj.

This is the best designed fermenter I have. I just wish that this lid fit the 5 and 6 gal bubbler.

Perfect for small batches
Used to make homemade Limoncello. Perfect for on-the-counter use. Plan to make several batches of short meade in this as well.

Great little Fermenter that is perfect for 1 gallon small batches. The airlock that is included was a bit rough to get fit to the kid, but I just used my old s lock and a stopper a d all is good. I plan on buying another soon.

Perfect for small batches.
Exactly as described. Easy to clean and has extra headspace for one gallon batches. I recommend it for developing new recipe

It's good.
It does what I need it to. I use it for fermenting kimchi. It has a nice large opening to access the product and easy cleaning. The only thing I didn't like was the cheap foam gasket. Everything else is fine.

What is the plastic translucent cap that ships inside of it for?
A shopper on Nov 16, 2016
BEST ANSWER: It snaps on the lid opening and works like an airlock.
What size stopper does it require?
A N on Jul 20, 2016
BEST ANSWER: The Little Big Mouth Bubbler does come with a stopper; it uses a #5.5 stopper in the hole on the grey lid. -Mike W, Midwest Supplies
Does this have a flat bottom? One that a stir bar could spin on for yeast starters?
A shopper on Mar 6, 2017
BEST ANSWER: This one has a flat bottom. So, I believe you can use a stir bar to mix the contents.
Is the stopper solid or drilled?
A shopper on Nov 14, 2017
BEST ANSWER: The stopper is solid. If you want to use an airlock, you have to buy it separately.
I've been doing my kombucha second fermentation in flip-top bottles to make it fizzy. Can the little mouth bubbler withstand enough pressure to make the kombucha fizzy?
A shopper on Apr 7, 2018
BEST ANSWER: I would be hesitant to pressure ferment in a glass container. Even if it could withstand a little pressure, I don't think that the lid seal will hold the pressure inside. I would recommend carbonating in the bottle and place in the fridge as soon as possible to slow any additional carbonation.
The gaskets on these are styrofoam. Once they go what can i use as replacement? Thanks!
A shopper on May 2, 2017
BEST ANSWER: Don't buy it this carboy its JUNK! Total piece of crap
What size/dimension is the jar?
A shopper on May 16, 2017
BEST ANSWER: It's just about 8 inches in diameter, and about 10.5 inches tall.
Is the outside glass at the top, where the lid screws on 5"?
A shopper on Mar 23, 2017
BEST ANSWER: I'd have to get mine out and measure it to be certain, but I would say that it is at least 5". It appears to be about the same diameter as the regular big mouth bubbler. For small wine batches this is just the ticket.
is there a hole in the lid for a stopper and air-lock?
P E on Jul 14, 2016
Love that these came back in stock! I ordered two and they just arrived today.

Quick question: do you guys plan on selling the carry harness that goes with the LBBB or know where I can get one?

Empty, the jar already has a bit of weight. Add a gallon or so of liquid and picking them up to move them around (especially up off the ground) may lead to breakage, clumsiness, etc...
M I on May 11, 2016
BEST ANSWER: We don't have one, or know of one that would work for that model. I'm not sure if there is a plan to make a carrier for the Little Big Mouth, but I will suggest it to our product development team! Thanks for the suggestion, have a good day! -Mike W, Midwest Supplies
Can you please explain this lid? Is it a solid plastic lid, or does it come with a hole in it?
renee c on Nov 28, 2015
BEST ANSWER: The lid has a single port built into in.
