I (Dave) suggested denaturing with a drop of gasoline. Joe cited that if you're going to run something around the range of E85 that denaturing would be a foregone conclusion. I (Dave) do not know much of what happens with respect to water/gasoline/ethanol when mixed in terms of water "dropping out". I do know that when I consume ethanol I tend to produce a fair bit of water... but that is off topic. As far as the home brewer is concerned, the only issues I can think of when dealing with ethanol is that a still, even under vacuum, will produce a maximum azeotrope of ethanol/water around 96%/4% respectively. I know that industrial fuel distilleries use a process with silica gel to remove the remaining water. As far as I can guess, if someone is distilling ethanol that it's really easy to get a higher percent of water and that would cause problems down the line at some point. Getting the highest concentration of ethanol in a still requires quite a bit of attention along with good equipment. There is a reason that industrial fuel distilleries use very tall column stills.
