My LHBS owner told me that anything that my rootbeer touches can not be used for brewing beer. I find this hard to believe, specially for the stainless steel corny kegs. I could possibly see this being true for the beer line from the corny to my Blichman Beer Gun, but I'm sure if I flush it out immediatly, or clean it with PBW it should be fine. And how exactly would it contaminate? color? sugar? taste?
Anyone got 2 cents on this?
