Not worth the effort.
Also, you really want a distillation process to remove water, not a rotovap.
For me, Everclear is just a consumable like many others in the process. I suppose if you are trying to pinch pennies, you could convert labor and electricity into higher grade Eth, but if you are pinching pennies you probably don't have a rotovap in your bedroom. You might have a
Source Turbo (which I have and it is now collecting dust - not a great product if you want control and thruput) but a rotovap us many thousands of dollars.
And does 99% EtOH give better product than 95%? Not for me. So why bother?
In my opinion, this is just a means to an end any my time is worth way more than a bottle of Everclear every now and then. Always in stock 5 minutes from home. No brainer.
