Default Foam. Foam. Foam.

I've just kegged my first double IPA. My kegerator temp is 42 degrees and my tap line is 3 feet. My psi is set at 10 but I am getting nothing but foam! It will eventually settle to a half glass of good beer put pouring is a nightmare. Is it too warm? Too high pressure? I have tried adjusting with no result. PLEASE HELP

Take the three feet of "tap line" and throw it in the trash.
Then go buy 10 feet of 3/16" ID beer line and install it...

Cheers!

My guess is too small and too short beer tubing. Also, you don't mention how you carbonated. Did you set at 10psi and leave for a few days, carb at 30psi and roll the keg, ...? Your pressure seems a little low at that temp to be causing teh problem, my guess is your carbonation process, or your set up. I would change to 10' of 1/4" tubing, vent the keg a couple of times, drop the temp to 36, and increase pressure to 12psi. Test after two days (maybe vent to keg two or three times over those two days).

Thanks! I will take care of the 10' line tonight. I carbonated at 30 psi for 2 days.

Here's hoping all is fixed.

Just make sure you don't get 1/4"!

Two days of 30psi @ 42°F likely overcarbed your beer, which on top of a way-too-short (and apparently too large diameter) beer line results in what you're seeing. After you install an appropriate beer line you'll probably have to shut the gas off and "burp" CO2 out of the keg head space until it calms down...

Cheers!

Here are a couple of links to articles helping determine the right size for your beer lines -

And Juan, I appreciate your comments and respect that you have a different opinion, but please don't mis-quote me and then call it "fixed".

Spend a couple of years here and you will find that extremely few folks get a good pour using 1/4" ID beer lines. Like, apparently only one.

And l would not recommend following the guidance provided by Beersmith et al as they are fundamentally flawed...

Cheers!

I do think it's important to understand the fundamentals of line balancing, so the Beersmith article can be very helpful on some level. But of course one just has to remember that the magic "XX psi per foot" number is never to be trusted.
