Something you may not know about Everclear...
Not all states allow full strength Everclear, but in those that do, Everclear is 95% ethanol.
Why is that number, 95% (190 proof),significant?
Two things.
First, it is stronger than any rubbing alcohol you can buy at the supermarket or drug store. Most rubbing alcohol is 70%, Many stores also sell 91%. You'll be hard pressed to find rubbing alcohol any stronger than that. Yes, Everclear is more expensive since it is food grade ethanol, so the Federal alcohol tax has to be paid.
Second, in distilling ethanol, there reaches a point called an "azeotrope" where the vapor pressure of ethanol and the vapor pressure of water are equal. The closer you get to the azeotrope, the harder it is to separate ethanol and water by distillation. So what does this have to do with Everclear you ask? The azeotrope for ethanol and water is....
95.6%
What this means is that when Everclear evaporates, the composition changes very litte.
Because it is so close to the azeotrope, the composition of the vapor is very close to the composition of the remaining liquid. So Everclear will retain it's strength even when a large amount has evaporated.
As long as there is a functioning Revenuer agency (AKA the BATF) The federal grubbymitts will fight you tooth and nail if you try to make 95% ethanol at home without a license. (actually there are ways around that but my lips are sealed
) But when the revenuers all start worrying more about taking care of themselves and their families, you can easily make your own ethanol at home.
