    Default End of keg Foam?

    I have been through a 1/4 and 1/2 barrel and I am almost through the second half barrel. I have been through the process of adjusting the PSI and Temp and seem to have it lined out pretty good. The question is:
    Is it normal to start getting more of a head when you are very close to the end of the keg? I usually get about 1" but it seems to be getting to two inches and almost inconsistent. I know the keg is almost out, just curious if this is worth worrying about or if it is normal. I am running a full size fridge with the conversions out the side of it. Bud light @14 PSI and 38 F, about 800' above sea level. These settings have been fine until the end of keg.

    Are you confident the temperature of the beer is consistent through the life of the keg? When you get down to towards the bottom of the keg, there is a low volume of liquid and it may get colder, especially if there is not an adequate amount of circulation in the unit. If the beer gets a couple of degrees colder, then 14psi might be over carbonating the beer left in the keg.

    This is just a theory, of course. Only way to tell if this is what's happening would be to take the temperature of the beer when you are near the end of the keg.

    be out of work and their dreams would be shattered. Then I say to myself,
    "It is better that I drink this beer and let their dreams come true than
    be selfish and worry about my liver."

    No. I can't tell the keg is low from a pour until it "pops" and is gone.

    Cubby is right thinking its a temp issue. If you don't have a fan inside running constantly than that is likely it....

    Yeah...I tend to get a different level of foam as the keg becomes empty.

    I would agree with cubby's theory, I have no extra foam near the end of the keg once it's aclimated to the kegerator. Air circulation keeps the temp diff to 1 degree inside my danby.

    I have noticed towards the end of a keg I usually need to adjust the t-stat a bit. Usually for the colder...
