I read the thread for the more personally applicable comments on toilets and light bulbs, I confess (I already know what we know about Roberts and ethanol destruction of all our engines - car, boat, lawn mower, rototiller, weed eater, etc.)
Now I’m curious - humor me, as I sometimes don’t know if a question is stupid - do you mean that vodka is made from “distiller’s grain”? I know what distillers are and I know vodka is useful for more than getting cat stains out of the carpet and ants off the sink. What is “distiller’s grain”? I know, I know, off topic. *sigh*
Vodka is a distilled beverage composed primarily of water and ethanol, sometimes with traces of impurities and flavorings. Traditionally, vodka is made by the distillation of fermented cereal grains or potatoes, though some modern brands use other substances, such as fruits or sugar.

Distillers grain is what the grain is called after going through the fermentation/distillation process.
The ethanol is ‘removed’ from the grain, made into whiskey, vodka, whatever. Others here are better source of information than I am on that.
The grain left is the distillers grain.
Distillers grain has many forms, depending on the process used, but it’s usually just wet soggy mash.
That’s the stuff used for livestock.
I’m not sure I gave a good answer.
