Keep your taproom close and your friends closer! Small enough to fit into your refrigerator, compact enough for easy portability; the Cannonball® kegs hold 1.75 gallons of your finest homebrew.

Great little keg system
The Cannonball is a great little keg system that allows you to take your prized brew out for an excursion without lugging a big keg and CO2 tank. The mini regulator with CO2 cartridge works great. The Cannonball fits into a small, dorm-style fridge, and thus allows me to have cold draft beer available without a keezer/kegerator. I rack my full batch into a corny keg, then transfer to the Cannonball as necessary.

Happy with my CannonBall
Treated myself to Cannonball last month taking advantage of a 20% discount. Filled it up with some Barley Wine I had aging for the Christmas holiday. Hauled it from TX to IA in an igloo cooler (fit just great). Worked perfectly for force carbonation & serving! Highly recommended...sure beats bottling, even for a small batcth

Compact and portable
I've been using this system for a month and I'm very happy with it. A 5-gallon batch of beer will fill three of these mini kegs. Due to space restrictions, I keep one mini keg in my regular kitchen fridge, while the other two kegs sit outside at room temperature. I ended up buying a 5lb CO2 tank with a regular CO2 regulator that I use to carbonate the beer. The only time I use the mini regulator with 74g cartridge is when I want to take the mini keg to a friend's home.

So much fun!
We are really enjoying our cannonball keg system. Just the right size for sharing homebrew. Also is great tor dispensing sangria. We call it the Sangria Machine". Only complaint is that it is impractical to use the little 74oz co2 cartridges that connect to the regulator. They don't last long. Would recommend purchasing a 5lb co2 tank for charging the keg.

Great purchase
This setup is perfect for neighborhood gatherings where the beer on hand tastes like it has been drank once. 14 pints makes sharing homebrew easy. This is well worth the money.

Great keg system for small batches!
This keg system is awesome. I love how it is small and compact enough to fit in my fridge. When brewing small batches, priming sugar needs to be much more exact - a little error in the amount of sugar or even the temp can mess up bottle carbonation drastically. This keg removes that guess work. It is absolutely great.

The only things I would have liked to have seen is some options when purchasing. I would have liked to upgrade the regulator to nitro, since that regulator can do both CO2 and nitro. In addition, the keg doesn't fit in my fridge with the snap tap attached, so it would have been nice to have the option to downgrade to the picnic tap.

Can I bring this to a taproom and have them fill it?
A shopper on Oct 10, 2018
BEST ANSWER: Yes, but then you risk contamination. If you trust the tap & your keg is clean - you should be ok. I would bring along the co2 & purge the keg of oxygen after you fill it. Remember that every time you disrupt the precious brew is a chance for it to go bad. Cheers!
Can you safely remove the ball lock adapter holding the regulator and CO2 cartridge after you have started force carbonating and after closing the regulator? When I threaded the regulator on the adapter and hand tightened it, it ended up pointing down with the CO2 cartridge pointing up. I'm thinking maybe I need to try rethreading again (maybe off 1/2 turn when started threading?) to see if I can get it in the proper orientation.
A shopper on Jun 11, 2018
BEST ANSWER: I've not used this to force carb (I use the Blichmann machine). You should be able to turn the black valve off and remove. Test this on an empty keg. Turn the knob to off and attach the ball lock. if you don't hear hissing in the keg then you can safely remove and re-orient. Good luck!
Can the black handle be unscrewed from the tap assembly? It needs to be shorter to fit in my fridge.
Steve S on Apr 25, 2018
BEST ANSWER: Honestly you don't want to use it. Your beer will come out way to foamy. I bought a new pin lock beer line that was like 2 foot long and has the tap on the end. It also stops the beer from getting super foamy when you pour it. The black handle tap they give you with the set sometime can be faulty, being that it doesn't spring back after the pour. I hope my advice helps! Cheers!!
Can you attach this to a CP filler to fill growlers?
Sabah S on Jan 27, 2018

You can us this as you normally would a 5 gallon keg, so you can fit it to a counter pressure filler. You would still need the CO2 tank, filler, double body regulator and associated hoses though.
Can I upgrade to metal compression fitting? Are there replacement plastic fittings available?
A shopper on Dec 29, 2017
BEST ANSWER: I'm not sure about metal compression fittings, but I have found replacement plastic fittings on the internet that fit (search Cornelius Corny Keg Ball Lock Disconnects SET Flared Gas In/Liquid Out +2 Swivel Nut Stems)
If I want to fill two kegs what would be the best process to store the second keg?
Jeff S on Dec 14, 2017
BEST ANSWER: You could add around .75 oz of corn sugar to the fermented beer in the keg. Seal up the keg. Then purge the headspace of the keg with co2. Let the beer condition at room temperature for 2 weeks. Then when you are ready to serve it should be carbonated.
Does this come as the picture shows? with the Beer Faucet?
Jeff S on Dec 14, 2017
BEST ANSWER: This kit includes :

Cannonball® 1.75 Gallon Mini Keg
Draft Brewer® Snap Tap™ Beer Faucet
Mini CO2 Regulator
CO2 Canisters - 2 Pack
Can the keg be filled to only one gallon and successfully force carbonated?
A shopper on Dec 7, 2017
BEST ANSWER: You can force carbonate with only a gallon in the keg.
Are the handles removable?
A shopper on Nov 29, 2017
BEST ANSWER: The handles are not removable but you need them for stacking these kegs on top of one another. The handles are "handy" for carrying the kegs around.
If I use this mini keg with the Co2 bottle to carbonate the beer, do I still need to use yeast after I brew it? I've only bottled beer.
A shopper on Sep 18, 2017
BEST ANSWER: If you use CO2, you do not need to add priming sugar or yeast. Cheers!
Will the smaller 16g canisters thread in? for serving.. but would a 16g force carb?
Chad R on Jun 20, 2017
BEST ANSWER: The 16 g cylinders that I'm familiar will not work (the ones I know of don't have threads). The 74 g cylinders are good for carbonating 1 keg from scratch and driving the beer delivery, plus driving beer delivery for another keg. They are not enough to carbonate and drive 2 kegs.
Having trouble deciding between this version and the one where I provide and separate co2 tank. Is it cheaper or easier to carbonate with a refillable tank than to rely on these small chargers? Pros/Cons of the two types? Thanks very much!
Roy H on May 7, 2017
BEST ANSWER: I have this and a 3 gallon keg with separate bottle. I like both setups, it really depends on how much beer I am looking to serve on the go. This setup does fit nicely into a cooler but holds just over 1/2 of the 3 gallon keg.
With this system do you ferment as you normally would and then after a couple weeks move the beer to this device where it is carbonated and ready to drink rather than bottling with sugar tabs and conditioning in the bottles? Is that correct? Thanks!
A shopper on May 7, 2017
BEST ANSWER: You are right! I transfer the fermented beer directly to my sanitized cannonball keg and carbonate it with a charge of co2. Usually about 20 psi. It only takes me about two days to get the level of carbonation desired. When serving I then drop the co2 pressure to about 8 lbs. Awesome product! Assembles and disassembles quick. Best of all, it fits right in our fridge.
What is the keg made out of? Will it corrode?
A shopper on Mar 28, 2017
BEST ANSWER: Stainless Steel and it should not corrode.
Can you connect this to a large CO2 tank? Would you need a different regulator?
A shopper on Nov 23, 2016
BEST ANSWER: You can connect this to a large CO2 tank. A big tank, say 5 lb, will need it's own regulator. I suggest using the big tank for force carbonation then use your micro regulator to take and serve. You'll use less CO2 cartridges that way.
Can the regulator also be used for nitrogen?
T O on Sep 10, 2016
BEST ANSWER: This regulator is not capable of being used with a nitrogen cartridge.
How many uses does the co2 cartridge last for.? What the main different between this and the one with the big regulator?
G U on Sep 1, 2016
BEST ANSWER: One 74 gram CO2 cartridge should serve roughly a dozen cannonball kegs, provided you are not also using it for force carbonation, and provided you maintain a tight seal with the regulator during that time.
