If I am following your logic correctly, then here is my two cents.
Unless you have a ridiculous lab setup, you will never be able to process sugar into 100% (aka "pure") ethanol. It is the other components of that non-pure distillation that would make it not taste good.
i never tried it (i would if i have the setup), but from the guy i am following he seems to reach almost 100%, maybe +99.6%
but when i think about it, the fermentation is just water + white sugar + yeast
so the leftover component of that none pure ethanol is just water, which should be fine, right?
unlike ethanol from petrol and oil, the leftovers would contain highly toxic materials
I can’t imagine ethanol would improve the taste of anything, and trying to make it yourself to drink sounds reckless to me. Just my opinion
i am not sure if you know this, but Ethanol is the thing that makes you drunk, it's the essence of alcoholic drinks, without it beer would just be a juice
wait....i liked him? when the dope addict at the brew pub cut me off from affordable malt, i had to resort to this sorta thing? ended up deciding aging on wood chips was cheaper then making alco-pop though....
