Hey everybody...I made a sweet immersion chiller out of 33 feet of 3/8" copper tube and what have you, and I have a quick question. I've heard that some brewers put their chiller into the boiling wort for the last 15 minutes of the boil to sterilize it. Does anyone do this? Will the copper effect the taste of the beer? Couldn't I just hit the chiller with my spray bottle of Star-San?
