      Aaron,

      1) Yes, lose the lower tube. I'd guess about having the upper two say
      30-50mm apart ? Its a matter of having them so that they can effectively
      contact the vapour - if too close, and one directly above the other, then
      you'd have less chance of the vapour getting to the second one. Has anyone
      tried offsetting these (e.g. if looking down from the top, one through from
      say 11oclock to 7oclock, and the other say from 1oclock to 5oclock), or
      putting them at 90 degrees to each other ? Taller column will mean greater
      purity, and less reflux needed to do so. However at some stage it becomes
      difficult to read the top thermometer, etc, and become a little more prone
      to tipping over if not restrained.

      2) Sometimes the hops in the beer can come through in the spirit flavor.
      Will need to try it, and see if they're a problem or not. Gees- if not,
      then you're on to a winner ! Another option, to reduce the amount of slow
      high reflux stilling, is to run them through a beer stripper first - e.g. a
      basic pot still, which will increase them up from 4-5% up to 30-35%. This
      would turn say 100 L of 5% beer into 16 L of 30% "low wines". If you get
      real fancy with your excess tubing, you could possibly design your still
      with an interchangeable column (but still use the same condensor), so that
      you can use it first to strip the beer, collect up the results of a few of
      these, then put the StillMaker column in, and do the purity run. The column
      for the pot still version doesn't need to be anything fancy - basically just
      something that would connect the condensor to the keg.
