Just brewed a Pils this weekend. I ran my chill water through an imersion chiller sitting in a cooler of ice water, then through my counterflow. Cant seem to get much below 68f.
Now I just had a new air conditioner put in my house and had them save the old AC supply line (about 25' of looks like 5/8" copper tubing. I was wondering if anyone has had any experience building a counterflow wort chiller using ethyl-glycol. maybe like using one of those wine chillers you see at the liquor stores. What do you think???
