FOAMY BEER :(

Hi,

Im a newbie on here so this is my first post. Apologies if this topic has been covered, however it causing me a major head ache.

I have purchased a Maxi Cooler 200 which I keep in my Shed. I have built a bar in my shed to accommodate the cooler and taps. I have CO2 connected and set at 26 PSI – as instructed by the gentleman who sold me the equipment. As the temp has warmed up outside 🙂 , I have decided to switch my cooler on constantly as I have wired up my shed with electricity.

I have recently bought a keg of Peroni, and tapped it in the shed. Before I used the cooler, I connected the keg to the tap using the C02 only and dispensed the beer as was. Slightly warm, up cold enough to drink. I have left the CO2 switched on over the weekend at 26 PSI. Since installing the electricity on Sunday, I connected the keg to the cooler and to the tap. Since the weekend I have received nothing but foam out of the Keg. I presumed with the cooler operating the foam would subside. I have even tried to turn the pressure down to 10PSI (after reading posts online)but this has had no impact, other than making the foam come out slower.

Have I over carbonated the beer by leaving the Gas on at 26 PSI? If so how would I resolve this? Is it possible?

I look forward to hearing from anyone, as this is starting to make my head hurt – and thats without any beer being drunk 🙂

Cheers,

Andy

  1. G’day Friend,
    I think that your snag requires the attention of a suitable guru.
    I am not the guru you require but,

    I don’t think that you have overpressurised the keg.I find it odd that adding a cooler into the system is causing a problem.

    Silly thing that comes to mind,back then when I used to put my time in at the Bell, the nozzles for Carling and Tetley Smooth looked identical externally .I wound up one evening having a foam party with the Carling while the Smooth was decidedley below expectations.The error of my ways was pointed out to me by my Gaffer and all was,eventually,sorted.

    The pointing out ceremony involved a brief but pointed lecture on the subject of nozzles that one can look through and those that one can’t.

    The only way my lecturer could have understood this is by making the same foul up as I did.

    The question that I am,eventually in the roundabout way that I go about these things am going to ask is,have you made my mistake and put on a nozzle that is inappropriate for purpose?

    Ronnie at The Eb has Peroni on the strength and has had no problems so far.I know this ‘coz I clean his lines.

  2. Hi paxtongk1
    As normal, its difficult to try and say what is wrong without being on site, but some thoughts: dropping the pressure will normally cause the product to froth more, why, the gas pressure is holding the bubbles in solution. If the fault started when the cooler was installed it points to the cooler area. Something could be stuck in the coil. If you can see the product in the beer lines you should be able to also see the froth in the line. go to the cooler and see if froth can be seen in either pipe. If its in both the inlet and the outlet then the fault is before the cooler, if its only in the outlet (going to the tap) the chances are its to do with the cooler. Last but not least, do they need cleaning?

  3. Hi, thanks for the posts. I can see there is a little foam in the line before entering the cooler, so I don’t think it is the cooler that is causing the foam. I’ve changed the gas tonight, and have seen a little improvement. I’ve also attached a flow control connection on the pipe to slow dispense. To your final point about cleaning the pipes, I haven’t, as the pipes are about 1.5 m in length total. I’m presuming that this will be a job for me tomorrow. Any tips ? Would running water or soapy solution through the pipes and tap work, or do I require solution?

    Apologies for lack of knowledge. Party time coming up in the form of summer, so trying to get this mastered by then 🙂

    Cheers

  4. With the cold weather and pressure setting at 26psi your lager would definitely absorb gas and be over-carbonated as a result, the proper setting would be 18psi at 54.c . 26psi would be ok in the warmer weather, however this weather it would be like you had a kegerator and should be something like 14psi. Thats the trouble with the garden shed you can’t regulate anything.On your last pointer clean your lines with cleaning fluid or else. 8)

    There are not many occasions when I take fright like you have just made me do.

    Read this,and do what you will with it;http://www.inndoctor.co.uk/cask-ales/cleaning-cask-ale-beer-lines/

    This applies to all forms of beer.

    Water is good as a precleaner and essential to flush out with after cleaning.

    A good browse of all available on this site will give you at least a passing insight into how to deal with it.

    Sorry if I sound a tad high handed,you have just scared the sh1t out of me…

  6. Thanks for the comments. Hands up here, total newbie here, so I might not explain myself verY well.

    So I took your advice and cleaned the lines / cooler. Unfortunately still foam. I’ve come to the conclusion that the keg is over carbinated. I have traced from the coupler, and small bubbles are racing from the keg.

    Now I’m not sure if I have made anything worse, but I have drained the gas from the keg, and turned gas off. Was this wise? Got about 1/2 keg left now, so wouldn’t mind saving, if poss. Will what I’ve done help ?

    I’ve also taken on board what you’ve said regarding the garden. Possibly a shout for a fridge / kegarator project?

    I guess you never learn unless you fail?

    Cheers guys

  7. You have not failed, you have succeded in finding how not to store beer 🙂

    How long was the keg connected to 26 psi ? I’m guessing for a while. The brewers spend vast amounts getting the gas content of their product right and thats what technicians use to set the dispence equipment. Which of course does not help you.
    I would never recommend someone to de-gas a keg for safety reasons but as you have; the gas will come out of the product until it is in equilibrium with the space at the top of the keg. So turn on the gas at a lowish pressure and just see what happens. Then increase it until you can just serve it. Without knowing what the volume of gas is now in the product it’s very difficult to say what pressure to set it at.

  8. Les,

    Cheers for your reply. After this, I’ve acquired a nice big fridge which will now house my keg – allowing constant temp 🙂 – (It kills me to waste good Peroni 🙂 )

    The Keg was connected for approx 3 days at 25 PSI. I have now set PSI at 10. It seems still to be foamy, but getting better and better each day.

    Thanks again forum – if your ever in the Wigan area, give me a shout and you can pop in for a beer.

    Cheers,

    Andy
