Depends on where you’re from and what the regulations are, might have been just non-denatured high% vodka essentially. As so much was needed regulations weren’t the strictest everywhere.

Anyway, I’m not gonna believe you before I see you take a mouthful of 80% alc and swirl it around your mouth and smack smack smack mmm. Without making any sort of sour face.

Because if you do, then that’s actually medically concerning, because that’s a poison and we have systems in our bodies to make us not ingest poisons easily. As in, that’s why we can taste bitter. Alcohol isn’t bitter per se but it’s a volatile solvent, and at those percentages it’s just not in anything way a taste. It’s a sensation.

I may be wrong, but I don’t believe you. You also say you don’t "really drink, so I’m thinking a younger person who’s had a small hit and enjoyed the aftereffects and can’t now discern them.
