Having some problems with my stout, hope someone might be able to offer some insight. Filtered about 10hl a few weeks ago and as per usual SOP gassed using CO2 to 1.95g/l (1 vol?), then nitrogenated using 100% nitrogen bubbled through at 3 bar and about 3degrees C for an hour. Pulled a pint off straight from the tank - beautiful cascade with a 2cm thick tight head, perfect! Kegged the stout and transferred to cold store but didn't put it into the bar for a couple of days. When I did put it on tap though it poured with a very, very small head (maybe 3-4mm). However after the second or third day of being on tap it was pouring with a fine big head again! This has been the case with all the kegs from this batch so far. We're using Guinness mixed gas at 40 psi to push the beer to the tap, is this dissolving into the beer and causing this effect do you think? Any ideas why the head disappeared in between tank and keg?
I am very puzzled.
