    Hello. So I have a kegerator with a "Nitro" or Beer Gas setup which means I'm pushing my beer through a Stout Faucet with a 70-30 Nitro-CO2 mix. Currently at 30 psi - 40°F and my beer line is only about 4 feet. I purchased a 1/6 stout keg from our local keg supplier, hooked everything up, started the pour and all I got was foam and more foam. I phoned the actual brewery that filled the keg and they told me that I actually have a CO2 pressurized keg at 2.5 volumes and that I should have asked for a "Nitro Keg" which they specifically fill at 1.5 CO2 volumes for those who want to dispense using Beer Gas, hense the foam! They said I was over-carbonated. Dang! Question: Is there any way to fix this without switching back to a CO2 push? Thanks for the help.

    You can try to degas the beer. It will be better but not perfect.

    Turn off the gas and leave the coupler attached. Either turn the shut off valve (the red lever on the regulator) or if you have a shitty regulator without a shutoff then turn the gas cylinder off.

    Shake the keg for a few seconds.

    Pull the PRV on the coupler, That is the pressure release valve, it is there to prevent over pressurizing the keg and automatically blows at around 60 psi, but you can also manually pull it.
    Leave the gas off.

    Do this every hour or so all day until there is very little gas escaping when you pull the prv. You want flat beer in the keg.

    Then apply 25 psi of gas and wait one day for the beer to recarb. Chill the keg to 38. You should have about 6 feet of choker ideally. Above 30 psi is typical but this is not typical. Next time you have a nitro keg you can apply 30 to 33 psi. And keep it cold. 38.

    Ready by 3/17.

    Good luck.

    As an addendum to Bills excellent advice, you can also do this overnight.

    With the gas off, coupler engaged and the keg depressurized, remove the gas line and Thomas valve from the coupler and allow the keg to slowly degas all night.

    Mid-morning, reassemble all the parts and turn the gas back on and you should be in good shape.
