Product Details

Compact yet easily expandable, the Draft Brewer® Flex System is the perfect place to start any kegerator, fridge, or keezer build. Serve your brew from any nook or cranny in your home with swivel-connection tap lines. With a Draft Brewe® system, no brew cave or home pub is too small to enjoy good beer on tap.

Take the guesswork out of perfect carbonation. Adjust the carbonation in real-time and guarantee perfect pours, even if your brews require different serving pressure. The ultra-durable CO2PO® Double Body CO2 Regulator makes carbonation easier than ever. Hand-adjustable pressure knobs are twist-and-go. High-contrast gauges give you pressure information in a quick glance. No more nightmares of bottle bombs!

And, with the double-body regulator, you can separately control the serving pressure of each keg! Have more than just variety on tap—serve each beer style at its perfect carbonation level. Flexible control also means you don’t have to choose between serving or carbonating your brew. You can force carbonate a second keg while continuing to serve from the first!

Enjoy your brew sooner when you can carbonate two kegs with a CO2 tank (not included) in 1-2 days instead of the standard 2-4 weeks in bottles.

Best of all, it takes just a swish of sanitizer to prep your Draft Brewer® kegs for the next batch. No more cleaning and capping dozens of bottles. The included Ball-Lock kegs are easy to disassemble for cleaning and have replaceable seals. 

Finally, a serving method as impressive as your homebrew. Bring homemade beer to a party and you’re interesting. Bring two kegs of homemade beer to a party and you’re a hero. Bring the Draft Brewer® Flex System and the party will never end!

When you're ready, expand your system with additional kegs and a gas distributor. Build a keezer using a chest freezer and the ThermoStar Dual-Mode Digital Temperature Controller. Keep more homebrew on tap!

Note: Keg Lube can help prevent CO2 leaks and prolong the life of the keg seals. 

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

When it came in the mail it looked just like it did online. All shiny and beautiful . I didn’t have any problems with it everything works great all I need to do now is learn how to use it properly . After years of botteling this is one of the best gifts I have received. My wife said she was tired of all the bottles around and that I was going to go to kegging. I just wonder why it took so long ? I would highly recommend the flex keg system .

Good value, but missing some fit and finish
I bought this a few months ago and just got my fridge set up for it a few weeks ago. It comes with the picnic taps, which I cut off straight away and connected to Perlick taps. My only real gripe is that the edges around the mouth of the kegs and the handle have a very sharp corner. I cut my hand on the lip of the mouth while I was transferring into it. I don't mind that it cut me, just that it was around the mouth of the keg, for sanitation reasons, that was a little worrisome for me.
Overall, I think this is a great package, I would buy it again.

Great kit for first time kegger
So far so good. Impressed with everything in the kit. Have my first keg carbonating and Karl's 90 Scottish getting ready for the second keg. So far my regulator is working consistently as opposed to other reviews. Northern brewer support cannot be beat.

Very Impressed
The kegs are very well made and the dual pressure regulator was much more robust that expected. I now have 10 gallons on tap and everything works great!

Kegging made easy
I was new to kegging so I decided to purchase this and man am I glad I did. All I had to do is clean and sanitize and I was kegged up and good to go. Love this flex system and the ability to pressurize individual beers. Buy and you won't regret!

What's the difference between this and the Draft Brewer® Twin Keg System?
A shopper on Aug 9, 2017
BEST ANSWER: This one comes with a dual regulator so that each keg can be at a different pressure. Where as the other one just has a single regulator that then goes to a splitter so that each keg is at the same pressure.
This system will allow me to disconnect and refill one keg while the other remains attached and carbonated?
A shopper on Jun 5, 2017
BEST ANSWER: Yep, It's always possible to shut off CO2 to one keg or the other, or to have just a single keg hooked up to the system. No problem at all!
Hello. If I got this system, would I be able to run on regulator to a manifold to keep multiple kegs at the same serving pressure to taps, then run the other regulator to pressure newly filled kegs? Thank you
A shopper on Jan 31, 2018
BEST ANSWER: I think you could, if all the beer in your kegs should be carbed at the same level. One other consideration is when you switch kegs on the manifold, unless you have valves for each keg connection, you will probably need to shut down the regulator for the manifold tomavoid CO2 loss during the switch. Good luck and kudos for all the production. Are you brewing small batches?
Is the dual body CO2 regulator expandable to accomodate a third keg with its own regulator?
A shopper on Mar 3, 2017
BEST ANSWER: Yes, the second regulator (farthest from the CO2 tank) has a high pressure gauge threaded into it's side. This is an unregulated port; you would just unthread the high pressure gauge, thread in a nipple with male threads on both ends, thread your third regulator onto the nipple, then thread the high pressure gauge into the end of the third regulator. You'll also need a low pressure gauge, petcock, and fitting for the third regulator. I was thinking about buying a second Flex Keg System and linking them if I ever get that into brewing.
Just got this system and legged for the first time. I blew through a 5lb co2 tank just carbing the kegs. I assume that's not right? Is there something I should be looking at on the regulator?
A shopper on Feb 4, 2017
BEST ANSWER: Make sure you leak test your system. All connections should be pretty tight, and then pressurize the system. Use a spray bottle with lightly soapy water and spray all of the connections, looking for bubbles coming from any leaking spots. If you find any leaks, check the tightness of the connection or change the seal or gasket for that link. Also, soray the regulator joints, as that maybe leaking as well. If you are still losing CO2 after that, see if there are any holes in the hoses. Also check the integrity if the welds of your kegs, as refurbished or used kegs could have faults in them.
How long does it take to force carbonate?
A shopper on Sep 14, 2017
BEST ANSWER: We usually leave the keg under pressure (pressure is based on beer type - usually @ 25 - 30 lbs.) for @ 72 - 96 hours. We then cool the keg to 38 - 42 degrees and bottle some of the brew. We chill the bottles as well prior to filling
Is there a mini-fridge that can fit both kegs inside? I don't want to take out all the shelves of my refridgerator to fit these kegs
Robert J on Oct 26, 2017
BEST ANSWER: I was unable to find one that handled two kegs + the regulator. I think for value, you're better off getting a small, cheap fridge. I looked a but and in the end, I went the Keezer route. All in, it was about $500 for a new freezer, temp control, taps, etc. I support two taps, but could expand the rig to four.
Newbie here. With the system can I just pout the whole thing in a fridge and not use a kegerator?
A shopper on Oct 20, 2017
BEST ANSWER: Thanks for contacting Northern Brewer. I understand you just want to put this in your fridge. Technically you could, however the kegs themselves are 25" inches tall and around 9" diameter. I don't know about you, but I would have to take out all my shelves to put my kegs in and then there would be no room for food. But who cares, food is overrated anyways. Cheers!
How wide is this set up?
A shopper on Apr 2, 2017
BEST ANSWER: Each keg is approx. 7" across. The Co2 tank measures about 5" across. The regulator from left side to right side of a connected Co2 tank measures approx. 12-1/2 across" (Photo does not show a connected Co2 tank). Hope this helps :)
overall height of keg?
john z on Feb 10, 2017
BEST ANSWER: The keg needs 25 inches of vertical clearance when the disconnects are in place! Cheers!
