I have a very small IC; 20' of 1/4" copper. It was purchased very cheap when I was doing 3 gal batches; now that I am doing 5 gal batches, it takes forever & uses a lot of water. What I did on my last batch was chill to 100°, rack to my Better Bottle, installed air lock, & placed on my basement floor with a fan blowing on it. Six hrs later it was at pitching temps. I hope this works; it saved water & allowed me to start clean up earlier, rather than stand there stirring.
