Some folks get bent because the H2O in the 151 PGA might pull out a bit more of the natural dextrose in the tobacco, causing the coil to gunk a bit faster and making the extract a bit sweet. It doesn’t bother me that much, since I perform a wick change and coil burn on a daily basis anyway and I don’t mind a little sweetness with my NET vapes.
There are also those that say an extraction with anything less than a 190 or 200 proof PGA is garbage… my opinion is, that is not true. In short… to each their own.
If folks want to spend their money on expensive proof EA or go through the process of using 3A molecular sieve beads to rid the EA of H2O… they can knock themselves out. Again… to each their own. I’ll go the cheap route… I’m easy.
Yes… pure grain alcohol; sometimes you will see me and others refer to it as EA (ethyl alcohol) or Ethanol.
