Ethanol is something you might use in a science experiment. In theory, it has no flavor, I would say, I'm guessing. But every time you distill something, you bring it up in alcohol content. So for example, if you have a still, we have a hybrid still, which mixes both the pot still and then more industrial stills that are just columns. To get really a high rectification, one would have to go through a lot of distillation, so to speak,. Each plate is a distillation to get a really high rectification.
