[usual suspect]

I bought a water distiller on Ebay for 120$ to take the fluoride out,
thinking; distiller? distill? still? still! I got me one of them there stills! made a batch of wine I don’t like, so my first experiment was to distill 5 bottles of cabernet wine. I believe it is called “Grapa”.
Alcohol turns to steam before because it has a lower boiling point. Simple alchemy. You can learn how to make a mash out of livestock feed and have an endless supply of 190 proof if you are so inclined.

Be very careful!

Search the internet - the ‘tips and tails’ of distilled alcohol are ethyl alcohol and WILL cause permanent blindness.

Military class 6 stores sell 190. I use it to clean electronics. I used to use Trichloroethylene, but there are mitigation precautions in ventilation, which if not adhered to can be causative to lung conditions that are a result from exposure. I could not justify the use of Trichloroethylene outside of an industrial set up (i.e. lab).

The distillation process is not quite so simple. Brewing generates toxic methanol and ill-tasting, oily fusel alcohols that have to be kept out of the distillation product that is to be consumed. The problem is that not only are ethanol and water close in their boiling points, but methanol and fusel alcohols also have boiling points close to that of ethanol.

Distilling reasonably pure alcohol requires some knowledge and skill, careful temperature control, artful timing, and the right kind of equipment. A repurposed home water distillation unit is just not going to be up to the task.
