Whiskey distilled strictly for fueling purposes. The best fuels are made from corn mash and filtered through charcoal dontchaknow.
Regarding charcoal: does anyone know how to “activate” it?
I can make charcoal easily enough from oak and two coffee tins, but there’s a step at the end wherein you soak it in a mild acid bath to etch out hollows and concavities on a microscopic scale.
It mystifies me.
