Moonshine is raw distillate that has not been aged in charred barrels.
Fore-shots of the distillate will contain some lower boiling methanol and must be discarded.
A chemistry professor told our class that during prohibition he would run analyses for bootleggers to make sure the booze was safe. He said there were more people with blindness due to methanol contamination going to the hospital then there were pregnant women delivering babies.
I heard a caution on TV this am that a lot of hand sanitizers from Mexico contained methanol and should be discarded. The hazardous warning is mainly aimed at alcoholics who may drink the stuff.
A shot of methanol can kill you and a little less can blind you. Trace amounts present in a lot of alcoholic beverages and food will not harm you.
