So for the past few months i have been simply chilling wort from my BK to plate chiller and then to carboy. Well after not being able to get below 70F in a reasonable amount of time i decided to give this whirlpooling thing a shot. Made a simple copper arm that comes from my pump to my chiller and then the BK and had below 65F in less than 8 minutes!:rockin: Have three lagers coming up in the next few weeks and this is a life and time saver. +100 for whirlpooling
