This is wrong. The boiling point of methanol is 65C vs ethanol at 78C. Methanol will come out first from distillation.
Oversimplified might be a better description but there needs to be a rule even dumb people can use
So the rule is: discard whatever comes first
If you expect every home distiller to understand the nuances of this you're going to end up with a lot of "accidents"
how did that work? did the Feds pose as some false flag bootleggers? do you have some sources I could read up on?
thing is, russia has a large tradition of home distillation (samogonka), and they too have tropes of people going blind. there have been a lot of cases of people dying because of bad alcohol, here's somewhat recent case: https://www.cbsnews.com/news/contaminated-cider-deaths-russi...
