Tangential—methanol poisoning from an improper brewing or distilling process is largely, maybe completely, a myth. Where toxicity events have occurred they are almost always deliberate or accidental adulteration, e.g. fortifying moonshine with industrially "denatured" (deliberately poisoned) alcohol. There has been a lot of sloppy journalism in such cases that doesn't question the myth, as well as Prohibition-era propaganda that lives on to this day.
