You can own a still, just can’t legally distill anything without a permit. And just so happens to be pretty easy to get a fuel alcohol distilling permit at no cost from the Feds. Technically anything you produce will be for your car, truck, lawnmower or whatever. Just isn’t meant for sipping......Distilling is not legal in the USA. neither is lots of stuff but BATFE will care and stomp your pets and shoot you when you get raided for it. FACT
The thing is that US law requires one to "denature" any alcohol distilled, which simply means poisoning it. Wood alcohol is added to make it legal. If the revenuers inspect and find good old fashioned ethanol that hasn't been tainted, you're busted.What you do with it after you make it is a personal decision. Maybe you put in fuel tank, maybe you drink. Legal to make with a Federal permit. Connect the dots and read between the lines.
