- If you’ve run into trouble with a tap that’s just pouring too fast, you may have accidentally over-pressurised the keg.
This video will show you how to back off the pressure in the headspace of your keg.
It doesn’t matter if you’re using A-Type Couplers, D-Type Couplers, S, G, K or any other coupler type.
We’ll show you how to back off the pressure and we’ll demonstrate using a few different types of coupler hardware attachments.
So, If you’re over-pressurised, this video will get you pouring perfect pints again in no time.
Thank you you helped this newbie out!
My kids turned my co2 up to 40 and it was like that for 9 hours maybe a bit less before I turned it down and then I disconnected my hose but didn’t take into account the duck bill so it say like that for another 24 hours and now it’s ok for the first pour after bleeding it then just foam again what do I need to do to fix it
Great stuff thank you for sharing.
Our pleasure! Any questions, let us know :)
Hi, thank You for very informative video.I m thinking to use sankey kegs for homebrewing,jwould it be possible to bleed oxigen after keg is filled up and CO2 is connected? I imagine first to fill up with CO and then unscrew CO2 valve on the coupler for release pressure ? Could You please help me with this ? Or shall I consider better to go with Cornelius keg system?
Go with a pressure fermenter. They're purpose built and have the same hardware on the lids as a corelius keg. Fermenting in corny kegs is something people do, but that doesn't make it the right vessel for the job. Wider and conical are the way. Check out our range here:

I have two keg taps. I have a half full keg on the left and just installed a second keg on the right side. Now that the new right keg is installed, the left one wont pour and the right one is extremly foamy and is coming out really fast. Could it be the new keg is too pressurized and it could that effect the entire system?
Hi ,I ve got from a frend a keg 30ltr ,seems like has a A type spear ,but very strange ,i can not open. Maybe I could send a picture of that keg?
send it to info@keg-king.com.au
My D type tap on my senkey keg has a pressure release valve just like the one one the regulator. I didn't see that option on the ones shown. Am I right in thinking that releasing preasure from that valve would accomplish the same thing?
Short answer is yes but you'll still have to turn your cylinder off before you pull the PRV on the coupler. We don't have the PRV on our couplers as a safety precaution in commercial cellar situations where venting off could cause gas pooling.
@@Keg-King Thanks for that last sentence.
I too wondered why you didn’t just close the CO2 bottle, then pull the PRV on the coupler, all my couplers have one.
I never thought of the suffocation factor of a keg being in an enclosed space & venting. Especially since a commercial operation probably would be using a much larger CO2 bottle.
I have a Guinness keg which is kept at room temp and ran through a cooler system. The pint usually starts out with the correct size head taste etc but generally deteriorated after 2 weeks or so with the head size reducing. Any ideas why this is? Also if I depressurise the keg and reapply the gas do you think this will bring the Guinness back to life so to speak.
Hi @tomcally3293. There's a lot of variables affecting your pour including temperature, pressure, line length and time. You'll need to balance the pressure to hold the carbonation at the temperature you're resting the keg. Doing this will balance the pour speed and the carbonation.
So if my coupler has the duck bill valve installed and I want to depressurize my keg am I able to do it with that valve installed? I imagine if I loosen that nut it will loosen the valve and allow CO2 to escape out from around the valve
Exactly.
Sometimes the duckbill valve has a washer type flange to it that will loose its seal when the nut on the coupler's gas inlet port is loosened.
Excellemt explanations.
Cheers and thanks for letting us know.
I've had massive foam problems with a full keg of Blue moon I've tried everything but I'll try this. The biggest clue was that I was getting air leaks from my coupler which should have been a clue. my guage only has a low side and still only tells you the pressure going in.
Foaming can also be about line length, internal tap issues and over-carbonation. The colder the liquid, the more gas it can onboard. This chart is a hand reference when setting pressure to a set and forget carbonation rate. www.kegking.com.au/blog/post/how-to-carbonate-beer-in-a-keg
I swear the blue moon keg I just tried about ruined my entire system. I just returned that keg and I am cleaning everything and replacing all my lines. I had solid foam almost every pour with trying EVERYTHING. Sorry to hear this happened to you as well, but I'm glad I'm not alone with it.
Hi mate, why my beer is pouring flat and taste different even though there is co2 and beerlines has been cleaned.
Thank you
Carbonation is a balanced combination of temperature, pressure and gas saturation. Clean beer lines will help you present your beverage in top quality condition, but a good pour is more dependent upon a clean connection at the tap and at the keg, combined with the right amount of line length for the ID of the beverage tubing to create a good pour in a 'balanced' system.
If your beer doesn't 'taste' right there could be multiple variables causing that to happen that you will have to mitigate and eliminate. Oxidation, carbonation, age, infection and a host of other possible factors could be affecting the flavour of your beverage.
Will the beer still taste flat and be over pressured? Mine comes out too fast/lots of foam and taste flat
Carbonation in a keg is really just a balance of pressure, temperature and time. If your beer is flat after pouring too fast with lots of foam it could be you are knocking out the carbonation and the beer itself isn't cold enough to absorb the gas.
Do I have to have the keg warm or can I do this while the keg is cold?
If you have set the pressure too high while the keg was cold and left the keg with the regulator feeding the higher pressure to the headspace for a prolonged period of time, odds are you've over-carbonated your keg. Good luck pouring it.
To Un-carbonate the beverage you need to make it go flat.
Just like if you leave a glass of beer out at room temp it will warm up and go flat, so too will the keg go flat at a warmer temp except you'll vent the headspace pressure in the keg as the gas comes out of the liquid.
@@Keg-King So after I let the keg get room temp, do I hook it back up before or after re-chilling it?
As the keg empties, do you need to add more co2 ? Or do you just leave the cannister on the same pressure until the keg empties?
I mean, is there enough pressure without continually running the gas to get the beer through the lines? Or you do need to keep adding co2?
Hi Benny. By setting your regulator to the right pressure for the temperature and carbonation level of the beer, the keg's headspace will get topped up everytime the tap is opened and the pressure starts to drop a bit. If you pressurise and then turn off the gas supply, you'll eventually get a slow pour and mess with the carbonation.
@@Keg-King thanks for the reply! I appreciate it.
Is it ok to set to 10 psi if the keg is already cold?
Is it normal that the co2 produces a sound like that ? Mine makes the same noise but I feel like that’s not normal, thought it was suppose to be silent.
The dispersion of CO2 will vary in sound depending on the equipment and the process. It can be subtle or it can be pronounced. Check valves and relief valves can definitely hiss and hum when they're active.
ok when I do this foam is comming out of the area. what does that mean? pressure was good all weekend went to pour one on Thursday and was foam. looked and pressure was 35psi. wtf..... is this keg ruined?
You can always depressurise and allow the keg to warm up, which as it does will release more carbon dioxide. Kind of like when you leave a sparkling beverage out in a glass, it goes flat.
You'll need to get the beverage cold again and leave it under pressure so it will once again carbonate and balance at the pressure and temperature that you require.
For most kegerator short draw systems, setting the temp to 2C and the pressure to around 8 to10 psi.
@Keg-King this is the 2nd time this happend. reading online it seems to be a regulator issue. Ditching the crap one that came with my unit and ordered a taprite. Hopefully this fixes my problem going foward.
Can you not just disconnect the gas and hook up a spunding valve and let it sort itself out?
Depends on how the gas input is attached to the coupler but in most cases it's easier to bleed off the excess and re-set the pressure. Of course, if your coupler has a PRV on it then you can simply turn off the gas supply and pull the PRV to relieve the headspace pressure.
How easy is it to set up a Guinness tap,without cooler
Serving beverages on tap is all about balance. So if you can get the beverage cold without a fridge or a glycol system its just a matter of how you get it out of the tap.
You can put the whole keg into a bin of ice and serve with gas or a hand pump or you can move the beer through a cooling device like a chill plate that you keep cold with ice inside an esky like this one:
www.kegking.com.au/cast-aluminium-cold-plate-chiller-cooler.html
It's not difficult to set something up so you can keep the beer fresh and carbonated with gas as you serve and it's even easier to dispense with a simple hand pump for when you're going to empty the keg in a single session.
TLDR: It's not difficult and doesn't require much equipment.
