Cannonball 1.75 Gal
This is a truly handy little keg. I would even say: invaluable. It works great and is so convenient for transporting and consuming beverages: beer, kombucha, etc. I know for the size it is rather expensive, but I use it as much as if not more than my 5 Gal corny.

Nice smaller system
I purchased this keg for cyser & mead. It works well, I've had to play with regulator a little. Also, the seal needs to be just right, I've had to disengage & reseal the ball lock to get it to seal occasionally.

Very Convenient
I was initially reluctant to buy this mini-keg kit because of the price. After all, I already had two-and-a-half gallon kegs, a regulator, and two 5# aluminum tanks. But I took the plunge, and I am really glad I did. 1 gallon of beer is the perfect size for smaller parties, and the entire apparatus is very lightweight and easy to transport. I haven't tried it yet, but I suspect a small CO2 canister like you use in spritzer bottles would probably provide enough pressure to dispense a gallon of beer if it was properly pressurized before beginning dispensing, making this even more transportable. I already have an adapter to fit the gas-in on ball lock kegs, so I'll try that next time.

Works great with picobrew.
This makes a great little system to use with my picobrew. Much better then minikeg for serving beer. Great customer service too.

A "must have" for weekend get together's.
There is nothing better, than being able to pour your friends, a draught of your HomeBrew! Easy to follow directions, for cleaning and reassembly. Fits perfectly on top shelf if refrigerator, and in my igloo, "cube" cooler!

a great starter, you will want to go bigger though
This little guy works great. If this will be your first keg set up you will soon find that unless you only do small batches, you will want more beer on tap. I am looking forward to being able to pack this baby in a cooler this summer and take it along or just use on the deck. Its works great!

Would a 2.5 lb co2 canister be sufficient to force carbonate for this keg?
A shopper on Nov 22, 2017
BEST ANSWER: I prefer the 5 lb that will give you a good reserve
Will this fit in a standard refrigerator so I can just open the fridge and dispense a beer?
A shopper on Sep 29, 2017
BEST ANSWER: the keg is sure small enough to fit into the frig. but you need to have a Co2 cylinder attached to dispense the beer out of this little keg. Depending on the size of that you might have issues for storage inside the frig. However you can also hook up a tiny little mini Co2 cartridge, but that ends up more expensive they don't last very long. I used mine once, but for some reason the hose connection didn't seal properly and I lost 20# of Co2 over night so I wasn't happy with that and just bottle everything now.
Is the out dip tube removable? I just got my new Cannonball and tried to disassemble but the long dip tube seems fixed in place, hate too force it to hard.
Kenneth B on Sep 18, 2017
Will this keg actually hold 1.75 gallons of beer as advertised? For test brews, I have a small batch setup that yields about 2 gallons.
Kenneth B on Aug 14, 2017
BEST ANSWER: I have three of these mini kegs. I've measured the volume to just below the gas dip tube and it's 1.71 gallons.
No CO2 to the keg. I got everything cleaned and hooked up in hopes of kegging today but I'm not getting any CO2 output from the regulator. The regulator indicates about 950 psi in my cylinder but zero on the output to the keg. What am I missing?
A shopper on Jul 16, 2017
I am trying to decide between this and the similar device that uses the disposable Co2 cartridges. Any pros or cons, or important differences you can comment on? Either I supply my own c02 tank or use those 74g cartridges... is one better, cheaper, or more efficient than the other? Thanks for any help!
Roy H on May 7, 2017
BEST ANSWER: Obviously using the CO2 tank to charge and dispense your beer is more economical. But for convenience, why not go hybrid? Use your CO2 tank to charge the beer to the proper pressure, then use a CO2 cartridge with an adapter to dispense the beer. I suspect you could dispense the full gallon with 1 or 2 of the small CO2 cartridges, and it would be a lot more convenient to carry to parties.
Is there a way to adapt this to a keg refrigerator that has American style tap system?
W B on Sep 11, 2016
BEST ANSWER: Yes, but what you are doing is modifying the gas and beverage lines to be able to be connected to this style of keg. If a person adds "MFL tailpieces" to a commercial beer Sankey coupler, you can easily set up your system to be able to swapped back and forth very easily. With the MFL tailpieces in place on the Sankey coupler, and "swivel nuts" installed in the gas and beer lines, you can swap the lines to have Ball-lock disconnects on them, so switching back and forth takes about 2 minutes. -Mike W, Midwest Supplies
Is it possible to inject nitrogen into the beer with this setup? How would you go about it?
W I on Aug 12, 2016
BEST ANSWER: The Cannonball Keg will work perfectly fine for Nitro beer as will any other keg. However, you will need special equipment for injecting; the nitrogen. A tank specifically designed for notrogen gas or Gmix gas )75% notrogen - 25% co2), a nitrogen regulator & a special faucet.
Can you advise how to carbonate the beer in this mini. Not sure what Psi and for how long.
T O on Jul 23, 2016
BEST ANSWER: Force carbonation for this, and all, kegs is a function of time, temperature, and pressure. In short the colder temps, higher pressure, and longer amount of time will lead to more carbonation. For most ale a keg chilled to 40F at 20 psi will be carbonated in about two days.

Can I use this to carbonate white wine and then bottle it?
J A on Jul 11, 2016
BEST ANSWER: That would be possible, but you'd need to bottle it in the right sort of bottles, and not regular wine bottles with corks; the CO2 pressure would push out the corks eventually. With the proper kegging gear, and a bottle filler, you could carbonate almost any liquid and bottle it up. -Mike W, Midwest Supplies
Can you explain what 'real-time carbonation control' means?
J I on Jul 6, 2016
BEST ANSWER: This is presented as one benefit to kegging, as opposed to bottling. When you bottle, you just throw sugar in the beer and seal the bottles, whatever carbonation you get is what you get. You can both increase and decrease the carbonation level in the keg with a simple turn of a dial and then waiting a few days, more or less. But, it means you can always fix carbonation issues or dial it in to your preference - the key here is 'control'. Keggers have it, bottlers leave it out of their hands after bottling day.
So another question! Can you run nitro with this system or is it CO2 only?
W O on Dec 1, 2015

You can run Nitro with the keg, but you will need a different regulator that can handle the higher pressure of nitrogen, and a different tap as the tap for nitrogen is far different from a standard tap. The nitrogen tap forces the beer/gas through a restriction plate to force the nitrogen into solution and produce a cascading head.
Are the components for the Draft Brewer Cannonball Mini Keg system compatible with larger kegs? In other words, can you mix and match with the Draft Brewer™ 5-Gallon Kegs? We have not gone beyond the 1.3 gallon mini kegs yet and are looking for the best and most versatile solution for the next step.
W O on Nov 29, 2015

Thank you for choosing Midwest! The components are most definitely compatible with the larger kegs as long as you purchase kegs that are the Ball Lock type.
