Whiskey is not alone in this. A good chunk of American vodka is apparently actually made from ethanol purchased from Archer Daniels Midland (ADM), the same company that distills ethanol for use as a motor fuel.
The important part of vodka is what water they are adding to that ethanol. It's not "just water" in that case, though it may very well be tap water (which is fine if they have good tap water).
Priced cheap, maybe at 80 and 160 proof options (normal and hi-test). Filtered tap water added at the bottling plant, and proud of it!
Something like that; I'd sure as heck buy it.
Someone might make a business in importing or making such products to USA :)
