I'm new to keging but why would you serve at a different pressure? for a faster pour? ,
according to the charts the desired carbonation volumes - should be reached at the (x) temp at (x) amount of co2 pressure.
I have been following this and i get good carbonation but my beer is all foam from the tap... so i bleed off excess co2 from the keg and it pours perfect?
I think your pouring pressure should be the same as your target volumes of co2 according to the charts.
Here is 1 carbonation chart http://sdcollins.home.mindspring.com...rbonation.html
