Wort Chiller

My immersion wort chiller design originally utilized two eight foot coils of 3/8" copper tubing. This was not nearly enough length to chill the wort down in a reasonable amount of time. My latest design uses fifty feet of copper tubing with both inner and outer coils. Even with warm Dallas tap water, I am usually able to chill the beer down to eighty degrees Fahrenheit.

During summer and when brewing lagers, I have begun recirculating ice water through the chiller using a cooler full of ice and a pump. The increased temperature differential cools the of the wort substantially faster. I have even chilled the wort to around 48 degrees Fahrenheit.
