I am going to making my own wort chiller here shortly and have a couple questions. I am going to do the standard coil style that fits insde the pot, my question is, has anyone ever did an additional small coil that spirals up the middle of the outter coil? Thus, giving the cool tap water a little more contact with the wort. maybe wrapping the larger coil around a korney keg, and the inside one around a spray paint can? :rockin:
