WebFeb 5, 2015 · if the ethanol used was 200 proof, then the presence of aromatics might be due to benzene, which is commonly used to dehydrate the azeotropic mixture of ethanol/water (95/5%). The benzene (as well as methanol) renders the 200 proof ethanol non-consumable which in turn cuts the tax rate compared to consumable alcohol (at least …
