So I initially force carb’d an Irish Red about 5 days ago and the pressure is now at 8psi but it’s super foamy and the beer isn’t that carbonated at all for all the foam. Any ideas why.

Are you using a short line or party tap perhaps?
 
Have you had success with the setup prior to this?

Without any further info, and if I had to guess your line is too short. It seems flat because all, or most, of the CO2 leaves suspension when its poured as all foam...

What temp are you serving at?


EDIT: just re-read OP. Do you mean burst carb or have you had it on gas for 5 days at 8psi? Its going to take longer to fully carb, like 10-14 days...
 
Yea my last ones were fine. The temp is about 30 deg F. I force carb’d at about 25 psi for a couple days and then had it at about 8 psi for 5 days and still foamy.
 
It might be overcarb'd. How many days exactly did you have it at 25 psi? Anything over two days might have been over kill, and I would dare say two days might be too much. It's very hard to dial in exact carbonation with the burst carb method. I usually set it to 12 psi and let it ride for 10-14 days. Never an issue...

FWIW. I know everyone has their own personal preferences, but unless your dispensing BMC or something, I would try to bump your kegerator temp and adjust serving psi. You might be having some freezing issues somewhere. Mine is set to 39F
 
Also, you need longer than a 5' beer line to dispense. What happens is the lack of restriction in a shorter line means the c02 "breaks out" of solution, creating lots of foam but leaving seemingly little carbonation behind. When you burst carb, go to 30 psi or so for no more than 36 hours, purge and reset to whatever you need to keep the desired carb level (likely about 10-12 psi), and go with 10-12' 3/16" serving line.
 
If it's over carb'd? I believe if you bring it to room temp, purge periodically, it should go flat rather quickly. Then I think you can start the carbing process again, but I could be wrong. I don't over carb with the set-it and forget-it method. ;) Not sure what effects this will have on the beer, but I guess it's better than a keg of foam.
 
Yea I even let all the pressure out, removed the lid and looked inside. It looks like all beer to me. No foam was even visible. [emoji53]
 
Looks can be deceiving my friend!

Juuuusssttt kidding...There is still CO2 in solution, same reason a normal pint will continue to bubble after poured. I'd let it warm up and go completely flat, then start over...
 
An over carbed beer won't be foamy inside the keg. The foam appears in your glass as the CO2 rushes out of solution as the beer is depressurized. I just fought this same problem. I didn't warm the beer back up, just closed the tank, pulled the valve and let the beer sit. I had to pull the valve twice a day for five days, then reset the pressure to 10, and it was better. That's the last time I try to carb in two days.
 
So I let it sit at room temp overnight, let all the pressure out and started over at 10 psi. Success.
