If it vaguely, and I mean vaguely resembles starch or sugar, you're not getting methanol. It's substantially harder to convert long polysacharides into ethanol/methanol than it is to convert starches and simple sugars, to the point that the less informed a person is, in the off chance they succeeded in making alcohol, the less likely there's going to be substantial methanol levels.

The vast majority of moonshine stills were just churning out unaged corn whiskey from animal feed corn. There is no risk of methanol poisoning in that scenario.
