my LHBS told me I could not use my wort chiller as a jockey box because copper produces a off taste in the beer when chilled and ran through it. Also another question ... I am planning on doing a homebrew spread for fourth of july and was wondering if I just iced my kegs and had small party taps off of them it would work fine and I wouldn't need a jockey box? Am trying to justify buying a jockey box!!! Guess I could rent one huh?
