Hi all
I recently picked up a metallic character coming from my left tap.
At the time, I put it down to the beer itself (as in, the beer was faulted). Erring on the side of caution and also chasing a mould problem, I did a full tear down and clean including beer line replacement (C02 lines not replaced). All parts were soaked in hot pbw with thorough clean (using only a chux cloth), saniclean rinse, ran saniclean through the lines for a few minutes to re-dispense. Still had the metallic character, where again, I put it down to the beer at the time.
Brewed a golden ale a couple of weeks ago. Was a split batch 1056 to one ferm, Denny's to the other (for competitive test). Threw the 1056 on right tap (fine), threw Denny's batch on left (the suspect tap) and sure as hell, Metallic.. but not initially. It took sitting on tap a day before I picked up the character, but it's there. Night and day there, compared to 1056 on right. If I had to put it down to a single flavour, it would be that of coins.. like I dropped a few copper coins into the beer glass.
I switch the line so that Denny's out post is now dispensing from OK tap at right, and bingo, no Metallic taste!
So I can put it down to the line/tap itself. Can anyone advise what part/part(s) could be causing this? I did not spot rust in any of the tap parts at recent teardown/rebuild. Not sure what else it could be?
Any advise appreciated and cheers.
