Dude ikr. You have to actively try to make methanol when you’re distilling, like only collecting the foreshots over and over.
And by that point I’d be super easy to tell it’s not regular alcohol because it will smell like nail polish remover and other volatile compounds.
Can you elaborate or link to further reading?
I assumed methanol is the first to go because of its lower boiling point — 65 degrees compared to ethanol at 78
