Great small batch add-on, with some reservations
The jar is great, nice heavy/thick glass, better volumn than a 1 gallon jug (a lot more head room). Large open mouth makes cleaning a breeze. Though after reading about sealing problems with the big mouth bubbler I really leaned into tighting the lid, I didn't have any leaks but at racking time I couldn't unscrew the lid! Good thing I had a large strap wrench, was the only way I could get the lid loose. So it's a good idea to get one if you don't have one already! Need to work on how tight it really needs to be tightened and still get a good seal. While setting up my first batch I found that the included blow-off tube didn't fit snug on or in the top so I took the 3 piece airlock apart and stuck a piece of 3/8" tubing I had on that and used to included stopper and all was good. I haven't used the Fermcap-s yet so I don't know if they will make a difference and I'm thinking that you'll not need them with the extra headroom & blow-off tube.Over-all I'm happy with the jar, blow-off tubing is a waste of money and NB needs to remove it from the kit. It's a good thing they've included a 3-piece airlock because you'll need it. Just add about 4 foot of 3/8" tubing to your order and you'll be good to go!BTW - I use the airlock/tubing setup in my 5 gallon batchs all the time during the primary fermenting, it's hard to find tubing that will fit the mouth of your carboy tight enough to seal correctly.

Small batch heaven
The Little Big Mouth Bubbler that comes in this kit is a must have for the one gallon batch kits. Total volume of the bubbler is about 1.3 gallons which provides that extra room needed for active fermentation. Easy to handle when full, solid glass construction, and a wide opening to make cleaning a breeze.

Little Big Mouth
I can make a 1.20 (maximum) Gal batch which gives me almost 12 bottles

Ideal for small batches.Extra room for fermentation. A must for the small batch that is very active. Exactly what I needed and would recommend it.

Perfect for 1 gallon brewsI
I only brew 1 gallon batches and this beats the 1 gal jugs if you want to add fruit or bark etc. I had been using plastic buckets but this is better since I can see inside. The glass is thicker than I thought and it's very easy to clean.I thought the blow off tube that came with it was too much and difficult to wrangle. It's easier to just use a stopper and thinner tubing.I was so pleased I wanted to buy another one but they were sold out.

Does the blow off tube attach the the threaded opening on the lid?
A shopper on Mar 1, 2017
BEST ANSWER: I havent used the wide blow off tube. I use a air lock and a rubber stopper. I think the blow off tube fits on the top of the airlock.

I really like the small batch brewing. I can brew more often without creating two cases of beer. I can play with recipes without committingto a full batch. If a batch goes bad I can blend beers more easily (fewer bottles). I have done two gallon batches (two jugs). I have a shorter brewday. I get to brew more kinds of beer.

If I get a good recipe I can do 5 gal too.
What are the dimensions of this?
Chris P on May 13, 2016
BEST ANSWER: 10 inch tall 8 inch dia. 6.5 mouth dia. perfect for a 1 gallon batch even a very active brew has room.
Do these still come with the older style lids (as pictured)?
Frank C on May 19, 2016
BEST ANSWER: The lil big mouth bubbler does come with the old style, screw on lid as pictured. Cheers!
is a mini siphon long enough to work with a Little Big Mouth Bubbler?
J R on Dec 17, 2015
BEST ANSWER: It's my go too for the little mouth I brew lots of Kambucha in the little mouth and think it's perfect
Is the glass dishwasher safe?

We do not recommend placing carboys in dishwashers.
When will the Little Big Mouth Bubbler be back in stock?
J R on Dec 21, 2015
BEST ANSWER: We were only able to get them as part of starter kits. I don not have an ETA for ones that can be sold individually, sorry. Let us know if we can help further! Cheers! James J.
what is the cleas plastic fermcap used for? Does this replace an airlock/bubbler? Do you just press fit onto the threaded flange? thanks!
R O on Oct 25, 2015
BEST ANSWER: The ferm cap S can be added at two times. You can add it to the boil to prevent boilovers. It's main reason for being in the kit is you can add some to the fermentor to limit the amount of foaming that occurs. IN high alcohol beers

it becomes more likely that the foam will grow more and cause a 'blow off'.
If a airlock is included in this kit, why do you still want a blowoff tube?
G Q on Oct 14, 2015
BEST ANSWER: For vigorous fermentations, a blowoff tube is preferable to an airlock because the tube will allow foam to escape without becoming blocked.
What size is the drilled stopper that comes with this kit? I have the fermentor, and airlock but I do not have the drilled stopper.
M I on Sep 14, 2015
BEST ANSWER: That is a No. 5.5 drilled stopper
