> this ideia of poison alcohol was propaganda done by the government during prohibition

imagine believing propaganda about propaganda.

congrats, man, you've come full-circle. methanol poisoning is very real, and methanol is definitely present in the "heads" of distillations (speaking as someone who's done this), and since there isn't a clear delineation between what is the "head" and what is the "body", it's entirely too easy (especially if you don't want to waste any of the good stuff) to accidentally include too much methanol in your distillation... which is exactly why alcohol is regulated

At any appreciable scale you get a reduced flow/pause in output as the mixture finishes boiling off the methanol and has to increase in temp before boiling the ethanol. It's a 10+ degree temp change so it's not instant. You need to be creating a small batch on a heat source that's way overkill to not have a defined difference.
