Kegged a beer 3 weeks ago and left it on co2 whilst away, came back last week and hooked it up to a tap and it was lovely and best beer I've made in ages. A week later and its now got very bitter and dry with a funny after taste, I did run cleaner thought the tap and starsan but there must have been something in there still.
I've got new O rings for the kegs, I need to look into poppet seals as they look like they have never been out.
Should I just replace all my lines and PBW everything including the taps ? I didnt know if I should try boiling the taps in piece's. Is PBW strong enough ?
