Good Product
Items came as expected. Currently have this set up in use with no complaints. New to brewing and testing the waters with 1 gallon to see if you want to make larger batches of selected beer? This little set up makes it easy. Thanks NB!

Perfect for experimenting
I originally bought this to make small batches of mead. I bought a couple of them, so I had one sitting empty for too long! I had a stout going into a secondary fermenter when I got the idea to put 1 gallon in this carboy with cacao nibs. I didn't want to do the whole batch that way, so it worked perfectly for me. I can see these getting a lot of use around here!

Good little car boy. Just wish the mouth was big enough to put the beer Thief into.

Can't go wrong
I have several of these now. Great value for small batch brewing. Happy that it comes with extra blow off tubing. I prefer to use that over the airlocks.

Flawed Glass
Mine came in with obvious flaws in it. There were bubbles in the glass and some of the bubbles had been broken, creating holes in the jug. I would not recommend this low quality product. Look elsewhere for class jugs and and save yourself from wasting money.

Just make sure you have a blow off hose hooked up as there is little room.

Topher on Jan 18, 2016
I've got 5 of these with 5 gallons of mead, but my siphon does not fit in the top. How have you guys gotten the contents out and into bottles?
Joshua L on Feb 1, 2016
BEST ANSWER: Either the 5/16" or the mini auto-siphon will fit into the top of the 1 gallon fermentor
Can you use this as a wine growler?
A shopper on Apr 10, 2018
BEST ANSWER: I did use it as a wine growler but my fermentation didn't work, This very well could have been my error though.

My cap cracked for my one gallon glass jug. I prefer rubber stoppers with a hole anyways, what size would fit this jug and do you sell one?
A shopper on Mar 12, 2017
BEST ANSWER: Number 6 stoppers work with our gallon jugs. Cheers!
does this come with airlock
W O on Apr 20, 2016
BEST ANSWER: Yes it does. It also comes with a screw cap and blow off hose.
Are there insulated jackets available for these to help keep warm and protect from light? Thanks
A shopper on May 7, 2017
BEST ANSWER: No, not yet! We don't have any small insulated covers for a fermenter of this size. In many cases a t-shirt or a towel would be enough to do the job, though.
I have one of these with three piece airlock and plastic screw on lid. I CANNOT get any air lock activity. I do have fermentation because I can see through the glass and at the top level of cider around edges I can see the co2 bubbling up to the top. Like a soda poured in a glass. Very small bubbles but it is fermenting. Just no airlock activity. Has anyone else had this issue? Is it a bad deal around plastic lid? I tried using a rubber stopper and one piece airlock but the stopper just pops right on out.
ken m on Jun 10, 2016
BEST ANSWER: Airlock activity varies so much - it's hard to say. If it is actively fermenting it should be bubbling...though if it has slowed down that is normal to not see activity. A size 6 stopper will fit these jugs. Perhaps some part of the airlock or cap are broken so it is not sealing. It is worth checking out where the gas is going - a spray bottle can help you determine where the gas is going.
Can Secondary fermentation be implemented with the 1 gallon receipes?
A U on Apr 9, 2016
BEST ANSWER: A secondary fermentation can most definitely be implemented when fermenting the 1 gallon recipes!
What about head space when doing 1 gallon batches of Beer? When doing 5 gallon batches you use 6.5 gallon carboy for primary. Obviously you guys know this. Does this carboy have plenty of room for the krausen?
W A on Apr 7, 2016
BEST ANSWER: It provides enough room for most 1 gallon ferments. High gravity(high alcohol) and higher temps during fermentation may result in extra foaming. There are 2 gallon buckets for primary if concerned. Otherwise, the 1 gallon mark on these jugs is actually slightly down from the neck so we find they give enough room. Cheers!
How I make a second fermentation? Thanks
