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

Great for Experimental Brewing
Used a couple of these to try out new recipes. Came with a three-piece airlock and blow-out hose. Worked great, highly satisfied.

Worked for MEad
Nice little kit, worked well for getting started on some small batches of mead.

perfect for mead split
Planned to make 5 gallons of mead and then break it down to 5 small batches so I could throw some fruit in for different flavors... these were perfect for the job.

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.

Great for experimentals and all level brewers
Whether you're a beginner trying to get some brewing repetitions (practice makes perfect!) or an expert making some experimental batches... (or even a beginner running experimental batches) this is a great product!I actually have 2 of these so I can run A/B tests on experimental batches before upscaling them!

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
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.
What size tube can fit in this jugs drilled cap?
As a blowoff tube?

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
