3 Gallon Keg System w/ new keg


SKU# 78513

Standard Shipping Rates Apply to this product

Same as our Draft Brewer® Single Keg System (K503), but with a new 3 gallon keg instead of a 5 gallon. The smaller size is easier to transport and takes up less fridge space, but won't hold an entire batch. Perfect for smaller kegerators and mini-fridges.

Best of all, it takes just a swish of sanitizer to prep your keg for the next batch. No more cleaning and capping dozens of bottles.

Includes everything except a CO2 tank to share and enjoy draft homebrew.

Three Gallon Draft Beer Kit
Excellent quality. Just add a CO2 tank and your all set for kegging.

Just right, not to big not to small
Unpacked it, read about it, than took it apart so I could learn about it that way. It's my first time with a keg and I love it, like the regulator too, the gage has serving pressure indicator, I like that little detail
Working great!

Out of the box seems like very good quality, well packaged. Keg arrived slightly pressurized, I am satisfied with this purchase.

First time kegging
I put an Irish Red Ale in the keg. Since I was new to this, experimented somewhat with fast carbonation. Beer turned out very tasty and did not last long! Still have not quite got the pressure right. Did use the priming sugar. Bottled the rest. Going to try an ale this weekend for kegging.

3 Gallon Keg System
Kegging system speeds up process which makes this well worth the money. Keep in mind though a CO2 system will put you in the hole another $100, but guess we are not in the business for cheap hobbies especially when we want our beer to taste good. You can place this in a standard mini fridge if you don't want to buy a kegerator as well and just takes a little maneuvering.

Fun product
I do 3-4 gallong BIAB batches so for me this is the perfect size and the best way to transport my beer to gatherings with minimal hassle. I bought this along with the Soda Keg CO2 charger so I can put this in my cooler with ice and walk down to the beach to enjoy some cold Speckled Heifer draft beer. Saving up for another to keep a the rotation going.

Works great
I needed to keep the "beer" fridge useful for kitchen overflow, sundry bottled stuff and generally for more than my keg system. This 3 gallon tank with an equally down sized CO2 unit permits the usual compliment of shelves in the old fridge I use. I may buy another.

Great Buy, Sharp Edges
The first thing I did with this keg was to cut myself on the factory sharp edge while cleaning it, I'm a clumsy guy though so if there was a way, I was bound to find it.I can't say that this is an essential purchase, but I find it a very convenient size for dragging to family/friend events, splitting a 5 gallon batch between 8 1-liter flip-tops and the keg leaves me plenty at home, and plenty to share. I love the 3 gallon size.I will probably buy another one of these someday, but I will probably also sand the top edge before I start cleaning it this time.

Works great. Easy to clean. Smaller size fits in small chest freezer with ease.

First Keg, Perfect Size
I live in an apartment and this was a good starting size for me to start with. Keg needs a good wash when you get it but so far its working great. So nice not to have to bottle all the beer. Have a batch of Karma Citra in it now, with the last 2 gallons bottled. Just add your co2 tank and you are good to go. I ended up getting a 5lb co2 tank and a paintball tank adapter in addition to this. I use the main tank to carbonate and the paintball tank to dispense in my fridge to reduce space. Still adjusting the right serving pressure but its great to have beer in a few days rather then a few weeks. Looking forward to taking this to the lake as well. Only problem is that I don't think my beer will last that long with the easy pouring. I am planning on getting a mini fridge for this soon and possibly getting another keg to keep a steady rotation.

Will CO2 cartridge fit keg?
A shopper on Apr 4, 2017
BEST ANSWER: Thanks for contacting Northern Brewer! I understand you want to use CO2 cartridges as opposed to a CO2 tank with this particular 3 gallon tank. I would not recommend using the cartridges for pressurizing the tank, because it would take several cartridges to even carbonate the beer in this tank. The CO2 cartridges (sku: 8083) are 74 grams and a pack of 2 are currently around twenty dollars. It would be much more cost effective to purchase a CO2 tank you can refill or exchange. Cheers!
Steve C on Nov 1, 2015

Either will work just fine. You can carbonate serve 8-10 kegs with a 5 lb cylinder and twice as many with a 10 lb cylinder.

Are these 3 gallon kegs with hoes stackable in the fridge? It looks like the plastic ring at the bottom fits over the top of another keg.

M R on Sep 21, 2016
BEST ANSWER: These kegs are not stackable. They would not be stable if stacked.
Why are these poppets not removable? So the rubber o-ring can never be replaced?
V B on Sep 17, 2016
BEST ANSWER: The poppets are removable, although destructively. they can be replaced with the universal poppets.
Do you have a similar priced product for nitrogen?
B M on Sep 4, 2016
BEST ANSWER: We do not have a kit for this, but the 3 gallon keg can be used in addition to our Nitro Keg System (kx10)
Should I be concerned that the poppets are not replaceable? What does this mean for the longterm lifesaver of the keg?
J D on Aug 3, 2016
BEST ANSWER: Not a big deal, as they will last a very long time. If there ever was an issue, they could be pushed out and replaced with universal poppets. The ones in the kegs are pressed into place, and do not fall out when the post is removed from the keg, but they can be taken out of the post if they become non-functional. They'd be damaged if pushed out, so do not remove them if they are still working correctly. - Mike W, Northern Brewer
Which regulator typically comes with this kit?
C O on Jul 23, 2016

Thank you for contacting us. This system comes with our CO2PO single body regulator, http://www.northernbrewer.com/co2po-single-body-regulator

What would I need in order to use this keg with wine?
S I on Jun 22, 2016
BEST ANSWER: This is set up for CO2 gas and wine is best used on nitrogen or argon gas. You can get a 3 gallon keg, a ball lock foam free tubing assembly, the mini nitrogen regulator, and a 18 g nitrogen cannister to easily set that up.
Why does it say the poppets aren't removable? Mine removed for sanitizing without any issue. The included instructions did not indicate otherwise and I just noticed the description here.
K E on Jun 4, 2016
BEST ANSWER: Perhaps a change was made to the design, or the poppets used. The ones I had seen before on these new kegs were "pressed in" and did not fall out when the post was removed, like some styles would. The only danger would be damaging them if they were intended to be left in place, but if yours were easily removed and replaced, I would not worry about it. -Mike W, Northern Brewer
Is there a Nitro Version of this kit available? I'd like to have the option to use 100% nitro for Cold-Brew Coffee dispensing in addition to using for beer here and there.
M A on Nov 8, 2015

The closest thing to that kit as a nitro version would be the following:



Both of which are currently out of stock unfortunately.

On the other hand

we do offer the Jacked-Up Nitro kit:

What are the dimensions of the keg with the couplers attached? I need to figure out if thishis will fit on the top shelf of my fridge or if I should go for the 1.5 gallon keg system. I need the overall height as well as the approx diameter if possible.
S H on Nov 4, 2015
BEST ANSWER: This is 18.5" tall with the disconnects attached and had a 9" diameter
Is the keg included with this package the same as the standalone 3 gallon keg (SKU# 40374) offered by NB?
