I've been wanting to try freeze distillation forever, but the concentrated methanol and fusel alcohols always kind of scared me away. Does anyone have any tips for removing these from the finished product? I was gonna warm the liquor on the stove to evaporate off the methanol but I'm wondering how one would get rid of the heavier alcohols.

    Hadnt heard of this, had to look it up. Seems like this just pulls the water out thus concentrating the remainder, but without any actual fractionation happening.

    I think your best bet is to unfortunately distill using heat to drive off the nasties. It's likely simpler than using a vacuum chamber to do it at lower temps.

    Can you make/attain a still? Jerry rig a fractionating column, condenser & two vessels?

      I actually do have a small still but I don't think could get the temperature finesse to fractionate ethanol from isopropyl
