OK. Made and kegged my first batch of dry stout. MMM! However I need some advice regarding carbonating the keg.
First, supposing I have a 20 litre keg (with 20 litres in it), how high should the pressure be? And how long does it take to permeate the beer?
Second, as you drink it, obviously the pressure will go down. Should one top up the pressure...and, if so, does one top it up to whatever PSI it was on first, or does the PSI change as the amount of beer in the tank goes down?
I would be very grateful for any answers.
