  • Problem with Guinness - spurting foam

    I attempted to put Guinness on my kegerator yesterday for the first time. It did not go smoothly, unfortunately. The beer would pour in foamy spurts that were quite messy. To be specific - it would just be pouring foam - and then a high velocity spurt of more foam would launch - and then it'd resume slowly pouring foam again. It would take maybe 5 minutes of settling before anything besides foam was visible in the glass.

    Some notes about my setup:
    Kegerator: Beverage-Air BM23
    Gas: 40 cubic foot, 25% CO2/75% N2
    Pressure: ~32 PSI (see notes)
    Coupler: Taprite CH5300U-SS
    Faucet: Taprite SF2003
    gas hose: 5/16" ID vinyl, maybe 8 feet
    beer hose: 3/16" ID vinyl, maybe 7 feet
    Temperature: around freezing (see notes)

    The coupler is brand new. Everything else has been used before and works fine (the stout faucet has not been used for beer though - only used with nitro coffee pushed with pure N2). I noticed that my drain container (as in, what my drain drains into, inside of kegerator) had ice in it - so I set the temperature to be a bit warmer and will check again on it in a day. I tried adjusting the pressure between 25PSI and 40PSI and did not really see any improvement in the spurting. I've left it at 32 PSI. One interesting thing that I noticed was that when I connected the coupler to the keg I did not immediately see beer rush into the beer lines. I am used to seeing that when connecting a new keg. With the higher pressure involved here - I definitely expected that. I only saw beer flow into the beer lines when I operated the faucet. Further, I can see big gas bubbles in the beer hose.

    Any thoughts on what I'm doing wrong? Thank you!

    I posted a video of my setup here: https://youtu.be/IwwbB4G2gDg

    It's feeling like a coupler issue to me, but I'm really not sure. Would sincerely appreciate some help!

      Coupler or the keg, there is no beer making it into the line. If you shake the keg, can you hear slush? Might be frozen.

        Definitely not frozen. measured temperature in my kegerator at around 34-35 Fahrenheit.

        Turning the keg on its side gets beer flowing. I believe this means bad keg spear. Any concerns with turning the keg upside down?

          You'd probably just do better to return it for credit and get a new one. Air temp is not a good measure of things in this situation, you really need liquid temp. Air is highly volatile and depending on the cut ins and cut outs of the unit, could vary +/- 5 degrees at any time.

            I got in a new keg of Guinness today and it immediately worked perfectly. Setup was fine - problem was a bad keg. I wonder how frequent of a problem that is. Methinks not very!

              It happens. Seals get nicked too. Everything is a wear item, it just sucks when it wears out on you.

                Just realized I never updated this thread. New keg started spurting foam after I posted. Eventually I tracked the problem down to a bad keg coupler. The latch on the handle had been installed upside down (at factory, not by me). When I first latched the coupler I would have put a lot of pressure on it - so initially the keg spear would be in the right place. But the latch allowed the spear about 1/4" of movement - and it would slowly, over time, move up and eventually disconnect from the keg. New handle with latch in the correct orientation fixed things and I've poured a couple kegs of Guinness perfectly since that fix.
