    New Kegs - Metallic taste

    Has anyone had any issues with new stainless kegs contributing a metallic taste to beer? I have heard of folks claiming that new fermentation tanks can contribute a metallic taste, so I don't see why a keg would be any different. Does anyone do anything to counteract this? It seems to be more an issue with the lighter beers.... I suppose that the obvious solution would be to put a heavier beer in them to start with...........

    Might or might not help, but with new kegs and new tanks, I'd run a strong acid cycle to passivate the metal. A nice strong pH might just show those metal ions who is the boss!

    my two cents......

    Prost!

    What brand of keg?
    I haven't seen that but still always run reductive dark beer through new kegs for as many cycles as possible.

    Citric Acid. Nitric works, but citric is better at getting the metallic taste out. Best is actually soaking in beer, but then you need to dump the beer afterward.

    I use leracid kms-10 from Loeffler chemicals on all new stainless to passivate.
