oh to foam

[fshnne1]

well here is my situation, I have to corneys full one is a rasp cream stout the other is a apple nut brown, when I originally tapped them and forced carbed. everything was good, now they are both about half full alls i can get from either is foam, I have tried to switch the taps, lower pressure at the co2 tank (2 pounds) and worked my way up

set up

5 pound co2 tank
7 foot beer out lines
2 through door taps (2 foot above the kegs)


used anywhere from 2 pounds to 14 pounds

beer tastes as though it is overcarbed

any ideas

Did you vent the kegs after you lowered the pressure? Sometimes the obvious can be overlooked. I had this problem, too -- and it took a while for the dissolved CO2 to come out of solution and re-equilibrate at the lower pressure, even after venting. The effect is also greater on a full keg since there is little 'headspace' in the keg to accept the CO2 coming out of solution.

yes I did vent the kegs

 

[FlyGuy]

yes I did vent the kegs

Sorry, I should have asked if you vented multiple times? It can take a while to lower the pressure on a full keg if it had a lot of CO2 dissolved in the beer.

Also, what diameter of hose are you using to connect from the kegs to your taps?

3/16 id is the normal stuff for beer line. It's what I use. I usually get the first glass of foam, but every glass immediately thereafter is fine.
