The best you’re going to get from a thumper is maybe 180 proof if you load the thumper with more 150 proof. A thumper is great for getting a 10% alcohol wash to 160-170 proof on a stripping run, where you’d normally get 130-150 proof. Not so great at getting your alcohol to that magic 190 proof number. For that, you’re going to need either a column or a shit ton of molecular sieves. I recommend the former. I’ll link some threads that might help.
