Everclear is 95% because that's the azeotrope of the water and alcohol
mixture. This means that it boils at a lower temperature than pure
alcohol or pure water. So the 95/5 mixture boils before the pure
ethonal boils and that's what ends up in the bottle. When alloying
metals a similar thing happens and you get an alloy that melts at a
lower temperatute than either of the pure metals. In that case it is
the eutectic.


As I understand it, in order to get a higher concentration of ethanol,
you have to remove the water through selective adsorbtion, or by
binding the water chemically.

Absolute ethanol is *not* something you want to try to drink (it'll
burn your tissues due to its very strong affinity to the water therein).



The dryers used to get higher than 95% are harmful to ingest. It's a small
percentage but bad stuff.
