HELP! Foamy beer... but not the whole keg?!

[Ashley]

So this may have been covered by others previously so apologies if this is the case.

I have a problem with every single keg I've put on. (Its only 6 kegs, about to put 7 and 8 on this weekened).

The last 1/3 of the keg gets very foamy and I have to run some off into a big jug before the foam stops, otherwise I get a glass 75% of head.

The first 2/3 or so run off brilliantly with no problems.

I watched some videos about foamy beer on youtube and they suggested that if you have too short a line to the tap this could be the problem but they also suggest that it would happen on every pint tou pull.

Has anyone else experienced this problem or is it just me?

Is this normal? Apologies if this question is really basic and I've just made a simple error

Check your dip tube next time it's empty. I had a small hole in one of mine although near the post that was a right pain as the gas aerated the beer on way out.

This happens on all 6 kegs though... and they were all brand new AEB kegs as well

Do you think that you're maybe slowly over carbonating?

What temp and psi do you serve at?

It only ever happens as I say when it gets to the last 3rd of the keg. Whether I go through a keg in a week of if I go through it in 2 months.

I have them set around 12 psi I think (just had IPAs on recently which I raised from 10 for an english bitter).

Not sure on exact temperature as I dont have one I can leave in there without it switching off.

Shall I try reducing the carbonation profile down then?

I will just note that if I run the tap for a few seconds into a big jug until it calms down, it then pours nicely again but if you wait 10 to 15 minutes and pour again, it does it again and you need to get the big jug out

It sounds like you might be foaming up in the line or the tap. If you've got transparent beer lines and you shine a light through them when you're expecting the next pour to be foam can you see bubbles inside?

If that's the case, what's the fix? All 6 kegs str empty at the moment... kegging 2 this weekend
