I’ve done a shot of pharmaceutical grade ethanol (99.5% de-ionized). It’s got more bite than 100 proof and is similar to Everclear.

That’s 199 proof at 99.5%.

The issue with alcohol over 190 proof is how that extra 5% azeotropic water content was removed. The issue being use of solvent type chemicals not typically associated with human consumption and safety :P
