Thanks, Todd, for going to the trouble of running that test. Can I run my own tests like the one you described if I can figure out how to make a condenser? Although I'm currently at the small batch (two liter-sized) processing level, I would like to develop and practice using a small condenser before I "graduate" to a larger scale.
There is a lot of distilling information on the web that describes how to build a condenser on large scale. If it's possible to scale one down, are there any guidelines for sizing one that would be appropriate at the five-gallon level? (I was going to try the flexible copper tubing used to install icemakers and the like.) Thanks again!
