Gav,
A glass of froth can be cause by a number or things:
1. Your beer is overcarbonated.
2. Your beer-line is too short.
3. Your pouring pressure is too high.
If you have over-carbonated, you have to take the keg off the gas and relieve the pressure with the release valve. Shake the keg, let it settle for a minute, then slowly release the pressure again. You need to do this a number of times.
#2 and #3: Make sure you're at pouring pressure (~80KPa/12PSI). If you're at pouring pressure, then your beer-lines are not balanced. You need to have around 2 metres of beer line at that pressure at 3degC.
Gav,
I did the same thing for the first 2 kegs and then WortGames sent me this table.
What I did to recover the beer was;
Pour the beer into a jug, that way the head will die down into beer over time.
Pull the ring on the release valve on the keg and blow out all the gas.
Drink a few of the beers from the jug, pull the ring, drink a few etc etc. Until it no longer burps after say 2 hours between drinks.
Note that you can still fill up the jug from the tap using the overgassed beer own gas (no gas bottle connected) while you wait as it may take more than one jug in time.
Set the serving pressure really low, as per the table and don't touch it again, ever.
Connect up and drink, the beer should be slightly flat now but will recover to the correct level over about 3 days. Adjust pressure as required for beer style. ie Wheat more, Porter less.
Easy.
And special thanks to WortGames for supplying the origional answer.

Kegs are so simple if you do it right from the start. Set the guage to 15psi and connect it to your keg - chilled is best. Leave it for 4 days. Attach line and pour. I have never had to adjust from 15psi. In four days it carbonates the keg and it is a good pressure for pouring - maybe a touch lower will help the froth.
Some people up the pressure to 40psi and then only leave the keg for 2 days or 1.5 days. I dont like the idea of this because if you are out by a few hours - your beer will be over carbed. Stick with 15 and 15 - you cant go wrong!!
yep, beer line is now 3 metres,have you lengthened your beer line? 600mm is too short
yep as per bonj's advice, if it is still overcarbed and im getting half/half why is there no bubbles rising, i have a brew in the fermenter that i have to empty this weekend, so not sure whether to keg it or not, ive wasted half a keg so far root'n about trying to get this workingDid you de-gas the keg in order to rule out overcarbonation? If it was overcarbonation causing it before, it's causing it again!
makes sense, thanks for the replyi think its finding a balance between fizzyness and pouring pressure. If u want gassier beer u up the psi/kpa but then u have to lenghten the line a bit.
yeah i wasnt sure about that, ive got the fridge set at 3degC with a temp controller, i cant see the beer being far from that at the tapAnother thing to watch is the fridge temperature. My chest freezer fluctuates between 1 and 5 degrees (probe loose), but when I tested the liquid temperature it was 5.2degC. I expected it to be around 3degC. As a result, I've upped the pressure on my system to 13PSI, and the line bubbles have all but gone. Haven't tested a pour yet, as I have a cold, and can't taste anything. No point drinking it if I can't taste it.
hook it up at 40kpa at 4 deg c as per HBS instructions
I should go metric for gas pressure, but being a kid in the 70's all I can remember are car tyre pumps calibrated in PSI... all this kPa stuff is confusing.
fwiw, I have a 2m beer line on my kegs. My pressure is set to 7-10psi depending on my mood mostly. I get a nice slow pour, plenty of head and a nice level of carbonation. I don't like it too fizzy. Anyway, it's nice to set and forget.
