These ethyl alcohol, or ethanol, emissions can then combine with moisture in the air and create “whiskey fungus,” scientifically named Baudoinia compniacensis. WebJan 6, 2005 · ethanol does evaporate FASTER than water, but it takes many (5 or 6) distillations to increase the ethanol content to greater than 50%. Given 10 or 20 distillations, you can get "absolute ethanol". This proves that water evaporates along with the ethanol (and does not get left behind), BUT that ethanol evaporates faster than the water.
