Default Eep, excessive foaming!

I just tapped my first keg and after 3 glasses I'm still getting 3/4 a glass of foam.

The keg is at 50F; been sitting in the kegerator for over a day and I have 10' of 3/16" beer line. I set my CO2 gauge to 12psi. When I open my tap the beer hisses and foams like crazy.

According to the beer line length/pressure calculator that floats around the forum I should have shorter lines and higher pressure(says 82" lines and 17.5psi) but wouldn't that create MORE foam?

Sorry, I'm a complete noob to kegging; just got everything set up about 30 minutes ago.

I just recently started kegging and had some initial problems too. How did you carbonate the beer?

10 feet? That's some line.

You say the beer has been in there more than a day, but that's not enough for it to carbonate fully. Did you carbonate it prior to putting it in the keg?

My first guess is you don't keep the line cold, could it be that the beer is warming up as it travels the line?

You may have a clogged or sticky poppet. Try taking off the connector and reseating it.

it's a pretty good size of beer line to have for a keg.

Did you force carb it? If you did, did you release the pressure before setting the 12 PSI serving pressure? Maybe your keg is still much higher than that if you forgt to release it?

Sorry, I forgot to mention it's a keg of craft beer; not my own homebrew.

As far as the lines getting warm; they shouldn't be. The tower is insulated fully and a good amount of cold air blows directly up the tower.

Between myself and a friend we poured 7 or 8 glasses and I noticed that my pour would have tons of foam but pouring his directly after would come out fine for some reason.

I'm sure there is some stupid step that I'm forgetting somewhere. lol

If that beer was warmer than 50 and you have only been chilling it for 24 hours it could be still be resettling and reabsorbing that co2 that was in the headspace while it was warm.

It is likely that the pressure in the keg would still be considerably higher if you did not purge it before serving. This would not show up on the regulator since that is measuring the pressure from the gas tank to the valve.

Purge it and give it a day or two under chill. You might want to purge it again during that time.

For starters, lower the temp to at least 45F and vent some pressure off the keg. It could be carbed higher than 12psi @ 50F equilibrium.
