Love this setup! Great for transporting and sharing
Bought this to take my first steps away from bottling, and haven't been disappointed. Even used it to force-carbonate part of a batch last minute for a get together with friends, and it worked great! Delicious beer on tap, that we put back into the fridge in between pours to keep it cold. I plan on buying a few more of the Cannonball kegs themselves to have a variety of brews ready to go. Family and friends are reaping the rewards of this system!

SWEET CANNONBALLS!!!!!!
This is perfect for a 2 1/2 gallon batch to fill and get some bottles done as well. Super fast shipping too!
November 19, 2015
Awesome
Easy to clean, fill, store, and it comes with everything you need. The regulator is certainly the weak point in the kit, there is a lot of play in the adjustment knob, but it works. Also, the nylon washers that come with the kit are super easy to lose.

Easy kegging
My first keg and and so far so good. Clear instructions which I follow to the letter. Easy to clean. I did have a small leak from the out post after I removed the ball lock but after reinserting and taking off it stopped. Fits in my small fridge with the 5lb CO2 tank and regulator. Regulator is easy to use. Gas and cobra lines worked well. Had a small leak in the gas line but a quick and simple tightening stopped it. Used twice and so far so good. Will be getting keg grease and some spare O rings.

A great option for small batch brewers to get into kegging
Overall- I have found this kit to be a great way to get into kegging while doing mostly small (1- 2 gallon) batch brewing. Just attach your CO2 tank and tighten everything up. Also a good option if you would like to split a larger batch of brew between keg and bottles. The value of all the included components is good in my opinion, and if you can get it on special (which run pretty frequently), you can get a great deal. It is seemingly costly to get into kegging with obscure sized kegs as there are few deals to be had and the 5g kegs are about the same price as the 1.75g new, but the packaged value of this kit makes the price more reasonable. Keg- The cannonball is clearly a centerpiece of this kit. The quality of the seams and welds is good, and the surface has that new stainless shine. The handles make it easy to swirl or shake when force carbing and seem like they also would allow for stacking (though I haven't tried this). Having used this keg a couple times now, I would say it performs as desired and I have no complaints. The governor- The staple regulator around here. Mine arrived well packaged and with no bends or defects in the gauge faces others have mentioned. This to me is a solid regulator, with the included MFL connections, a check valve, and gauge gaurds. The only Thing I wish it had was a larger rubber diaphragm (which other regulators do and makes more fine adjustments in pressure easier). Overall, it gets the job done for what I need it to do, again a more reasonable value in this package deal. The lines- Simply put, solid ball locks with MFL connections and appropriate lengths of tubing. Easy, and exactly what I would want, ready to go. -Hope it helps
Awesome
Great item, have not used it yet but looking forward to it.

BUY THIS NOW!!!
This is an amazing system. Kegged my batch a week ago and set it up in a kegerator and I tell you what delicious brew on tap is amazing...., and dangerous lol. If you want to keg a small part of your batch and bottle some too and not take up massive room in your home this is a good way to do it ...BUY THIS NOW!

Great product!
Great way to get into kegging!

Cannonball!!!!
The Draft Brewer Cannonball 1.75 Gallon Keg is top notch. Matched with a great gas regulator is a perfect gathering keg. At just over 15 pints I am able to give a taste of my latest brews to my friends or neighbors where ever I'm at. Pleased I purchased it!!!
January 29, 2016
Excellent
This little guy is awesome. I do small batches of cider and cysers, and this is perfect for a small batch keg. High quality construction and materials. The included regulator works well although the adjustment knob could be bigger (tough on your fingers). It also includes a 5 ft 3/16" liquid line and picnic tap, and the line is a bit short for foamless pours. But overall it's wonderful.

I just received this kit and purchased a standard 5lb CO2 tank to use with it. If I was to put a gallon (or 1.5 gallons) in this, what would be the best way to carbonate the home-brew? I have seen a few methods but none for such a small keg? Set it at 12 PSI and leave it alone for a week at room temp? What do you guys recommend as the best approach to force carb? Thanks
D A on May 17, 2016
BEST ANSWER: The most reliable way is the 'set it and forget it' method where you set at 11-15 PSI and leave for a week or so. You could set the regulator to around 30-40 PSI and set for a couple of days and that should do it faster. Some will even shake the keg at 30-40 PSI and this shaking can get the beer carbonated much faster so it can be enjoyed in the same day. The latter options run the risk of over carbonating though which will result in taking longer than the first method. Cheers!
What are the dimensions of this keg, regulator and co2 tank? I'm planning to buy a standard mini fridge to store it. Will there be enough room?
M I on May 16, 2016
BEST ANSWER: Keg Dimensions
Base Diameter (diameter of body): 9"
Height of Body (not including handles): 9.375"
Height with Handles: 10.75"
Base Inset/Top of handle diameter: 8.5"
depending on which size CO tank it should fit fine.
I'm interested in getting this for my husband as a gift. I don't know much about brewing but he's passionate about it. What size C02 tank would I need to purchase with this and is there anything else I would need to get as well?
A C on Mar 18, 2016
BEST ANSWER: I use a 5lb tank - but I use CO at work so I can change out tanks when needed. My one tank has supplied at least 20 5 gallon batches of beer and has still not run out. The regulator that comes with this system is a really good regulator so he shouldn't have leak issues.
Is there an instructional video available?
S M on Nov 25, 2015
BEST ANSWER: We do not have a video specific to the cannonball system but here are two links to videos we made on kegging. The information is all the same

the only difference is size. Cheers! James J.

So do you have keep a keg in the fridge while it carbs up? Or can you let it sit out at room temp until it's ready then put it in a fridge? I've never kegged yet so I'm not sure. Also do you have to have the co2 tank attached at all times while it carbs and for dispensing or is there residual pressure to last a little while without it being connected?
R T on Sep 5, 2016
BEST ANSWER: Carbonation is all about partial pressures. The pressure in the tank is higher than that in the keg. You can carb while its at room temperature. But! It will take a long time. Not as long for 1.75 gallons as for 5 or more, of course. Also, it will take longer the less full the keg is, the warmer each the tank and the keg are, and the closer in temperature they are to each other. The CO2 will infuse into the beer easier/faster at colder temperatures. Note, if you put the CO2 tank into the fridge with the keg, it will slow the carbonation process. Also, the CO2 will remain in the beer longer/easier with less free headspace (the fuller the keg) or as long as the pressure in the headspace is greater to or equal to the desired CO2 in the beer.

You can dispense from the keg without the CO2 hook-up, but then you're using the carbonation in the beer to force the beer out; that is to say, like a bottle of soda, when you first open it to the outside air (bottling, tapping into a glass, serving, etc) the carbonation wants to leave the beer because there is less partial pressure outside and in the head space in the keg (as the keg empties. The CO2 leaves into the head space AND will create (IMHO) an undesirable amount of head. If it's not hooked up to the CO2 tank, you're losing carbonation as you empty the keg. Use a little bit (4-12 psi setting from the keg) to dispense.

So, shorthand:
Cold full keg (Google Force Carnonation Chart) and room temperature CO2 tank for fastest and most controlled force carbonation.

Reduce CO2 tank pressure for dispensing (Google: serving PSI from (x) gal. keg).

For the science-y geeky types out there:
If you don't empty the keg, adjust the PSI back up a little to ensure you're adding a bit of CO2 back into the keg for the loss of pressure into the greater head space remaining in the keg - potentially negligible depending on the beer and how carbed it is and how much beer you've removed. This can be a difficult thing to calculate if you're not up for it.

Science is your friend, love your Google searches! Or you can wing it. And as long as your yeast were good and your recipe was alright, it still may taste great, it just may feel a little less great if you over or under do it. Don't worry too much. Learn as you go and enjoy every sip.
Hi guys, I was just wondering what's the diameter of the mouth on the keg? Do you have any isometric images? Just thinking about the ease of cleaning... getting my arm in, in case my brews leave some trub or yeast in there.
D E on Aug 28, 2016
BEST ANSWER: It's a standard Corny keg opening, so if you have thin arms you can get in there. Its only about 10 inches deep so a carboy brush will work pretty good, otherwise pbw soaking overnight will turn it back to sparkling in no time.
Could I use this to carbonate water? I do some homebrewing but we also go through a lot of seltzer and I'm tired of the poor build quality of Sodastream machines.
D A on Aug 11, 2016
BEST ANSWER: I don't see why not? I don't know much about seltzer, but this allows your to dissolve co2 in liquid, so I don't see why not
I would like to use this for Cold Brew Nitro Coffee, can I attach a 5lbs nitrogen and use this for my cold brew nitro coffee needs? Thanks!
C E on Jun 29, 2016
BEST ANSWER: I am using it for nitrogen coffee. I'm not sure what you mean by 5lb nitrogen? I know nitrogen tanks are expressed in volume (for example I have a 22 cubic foot tank - which is a little larger than my 5 lb CO2 tank). Bottom line is yes you can use nitrogen and use it for coffee, but make sure you have a proper nitrogen tank and nitrogen regulator, as you have to push 30-35 PSI through it as opposed to the CO2 standard of 5 - 15.

But again, bottom line, yes you can use it for nitro coffee (it's delicious!)
I have a Cornelius hand held charger and was wondering if there is a way to connect that to the Cannonball input regulator?
D S on May 26, 2016
BEST ANSWER: If its a ball lock interface, it should connect , seal and pressurize the keg. Unsure if it will be enough to carb.....May be enuff to dispense
I use a 5lb tank myself. it works well and fits in the fridge after moving the shelves around.
jake on Mar 18, 2016
BEST ANSWER: The standard 5lb tank will definitely fit in a fridge with the cannonball keg, though there will likely be a need for a little reorganization depending on how your shelving is set up, and how tightly packed your fridge is.
Allowing for room for c02 how much beer can this hold/dispense? Could you expect an average of 18 12fl oz bottles out of this?
M S on Feb 23, 2016
BEST ANSWER: If you put a full 1.75 gallons into it, that would equal 18 12 oz beers. Not much space is needed up top, usually just an inch or so is left in the top of a keg when filling it. This is so the gas-in dip tube is not submerged, so liquid cannot flow back up the gas line if the CO2 tank pressure dropped. -Mike W, Northern Brewer
Will this support an internal gas tube with a carbonating stone?
A C on Feb 5, 2016
BEST ANSWER: There is a gas dip tube You could hook up a carbonating stone to that. I hope that answers the question!
Can this regulator be used with a 20 oz CO2 canister or will it require a different regulator/additional equipment?
O R on Jan 2, 2016
BEST ANSWER: The regulator in this system is set up for standard CO2 cylinders (2.5lb, 5lb, 10lb, etc.). I don't believe I've seen 20oz CO2 cylinders/cartridges with that exact threading before, but I could be wrong.

Cheers, Gabe from NB
Will a 20oz CO2 tank (paintball) provide enough gas to carbonate a batch with this keg?
Casey S on Dec 11, 2015
BEST ANSWER: I would think a 20 oz tank would have plenty to carb and serve a batch this size, though I haven't tried it. Best solution is a larger tank at home for carbing and a paintball tank or cartridges as a traveler. I just got one of these, think I'm going to go with the mini paintball tank regulator for mobility and I have a 20 LB tank with regulator at home to carb.
Just got this, super excited to use it, but have some questions - thanks!

Q1: On average, how long does it take to carbonate the amount of beer in this mini keg?

Q2: How much headspace are you supposed to leave?

Q3: Can you bottle after force carbonating your beer from this keg? if so, what equipment would one suggest?

Q4: Once carbonated, in how long should one consume all of the beer?
S A on Dec 10, 2015
BEST ANSWER: Thanks for the questions! The time to carboante varies based on your approach. If you set and forget the keg at a certain pressure it will take about 1 to 1.5 weeks to carbonate. Look at the pressure chart we post. Otherwise, you can quickly carbonate by setting pressure higher like to 30 psi and then shake the keg. This can over carbonate so can take some practice to get the procedure down, but that approach can take as little as about 4 hours.

Just leave enough so the liquid is not reaching the liquid dip tube. That way you won'y spray liquid all over when relieving pressure.

You can bottle from the keg. It can be as easy as getting a bottle filler and a #2 stopper and using the black plastic faucet. The correct equipment would be the last straw bottle filler or blichmann beer gun, which will require a splitter or distributor so you can supply two feeds from the CO2 tank.

The time to consume is the same as if bottled. Drink it all within 6 months roughly for every beer. Highly hopped beer and highABV beers will take longer to go bad, but using 6 months as a base is a wise assumption. Cheers! James J.
What additional items do I need to purchase, beyond the beer ingredients? Do I need equipment to pressurize the tank, etc.
A E on Dec 7, 2015
BEST ANSWER: Hello Jim,

Thank you for choosing Northern Brewer! Other than the equipment and ingredients to brew the beer, you will need a CO2 tank to carbonate the beer, and to use as a carrier/propellant for serving the beer. I hope that this helps!
I have purchased the Draft Brewer Cannonball Mini Keg System which is in shipment. My question has to do with cold conditioning. When I bottle my unfiltered beer I give it many months in a refrigerator to cold condition. The result, especially with fruit beers, is a mild smooth taste that I love. Can this be achieved with this cannonball system?
C A on Nov 1, 2015
BEST ANSWER: You can treat any keg like it is a big beer bottle. Meaning that if you would normally cold condition your bottles for a few months then you could certainly do the same here.

Gabe from NB
Can you bottle from this?
David C on Oct 31, 2015
BEST ANSWER: Not really. But if you get the growler wand you can fill growlers from this keg system nicely.
Can you use this for small batch kit. ( the 1 gallon kits). Is it too much extra space @1.75 gallons.
F U on Oct 28, 2015
BEST ANSWER: Don't know; I only make 5 gallons batch. Keg some; bottle the rest. However, it shouldn't a difference, gt eget the air out , purge it with co2.
When you load and charge the canister, how long will the beer stay fresh with refrigeration? Thanks, Steve
D S on Oct 27, 2015
BEST ANSWER: With refrigeration the beer will be fresh for 6 - 12 months for best results. Since this uses all CO2 the beer is not oxidized and ruined by outside oxygen so will stay as fresh as if in a beer bottle.
When will this item be in stock?
K E on Oct 16, 2015
BEST ANSWER: It should be back in stock next week. If you add the product to your Brew List you'll receive a notification as soon as it is back in stock.
what size and length is the beer dispensing line in this kit? How much resistance does the line provide for dispensing?
Timothy H on May 28, 2016
BEST ANSWER: The tubing is 3/16", and 5 feet long. 3/16" tubing has a resistance of about 2 lbs./foot.
I am looking to make root beer. I am very new to this process. Is this the correct type of system that you recommend for root beer and similar soda applications? Many people use CO2 to carbonate. Others like to use yeast. I understand glass bottles can explode over time. Will the keg be able to handle this type of process? Is the pressure relief valve designed to correct for this problem? I would appreciate your input on this.
J O on Dec 19, 2015
BEST ANSWER: This system would work well for root beer.
What is the total height with the "Snap Tap" attachment (without handles)?
hammy on Nov 3, 2015
BEST ANSWER: The keg is about 9.375 inches tall and with the snap tap installed it is about 17" tall with handle. If you take the handle off the snap tap you gain about 2 inches of clearance. For ease of use it is recommended to have a couple inches of extra clearance.
Any idea when back in stock
J O on Sep 20, 2015
BEST ANSWER: Hi Joe

We should have more kegs back in stock around the end of October. The website should be updated once they are back in stock.
Can the regulator be hooked up to nitro for cold brew coffee?
D L on Sep 16, 2015
BEST ANSWER: The regulator this system comes with is a CO2 regulator. You would need a nitrogen regulator if you wanted to hook it up to nitrogen.
