There’s an idea. The alcohol should kill off most of the toxins but one should probably sterilize the outside of the container just in case.

The alcohol should kill off most of the toxins

Alcohol is a solvent that may chemically change the nature of some toxins, good or bad, but it will only "kill" bacteria.

I'd be worried about what the "additives" would be introduced to modify taste, color and clarity. For some reason I have this mental picture of Prestone containers beside every aging barrel.
