Oh I dont buy vodka. Thats what rep samplings are for. Or friends who do like vodka. And since I dont currently work much with liquor, I’m safe.
But substantially I do this for things that I dont have a professional (or current professional) interest in. Because i want to understand things.
I read books I dont like. And almost always finish them. And sometimes reread them. If I have a food I don’t like. I work on learning to like it (current project raw tomato). Movies, music etc. Always pulling them apart, testing them out. If i have a major personal preference its to understand things.
Which is why I’m trying to stress that if your interest in whiskey is knowing about it genuinely. Understanding it, as fully as possible. A real enthusiast interest. You should be doing it this way. And through that hardline ideas like never ice start to seem foolish.
If your interest is instead in impressing people by looking like you know what your talking about. Or making a big deal out of consuming something purportedly expensive. Or because of some cultural connotations. Well then go buy something overpriced from Johnny Walker and go hang out with guys who constantly reference that quote about glancing at a bottle of vermouth. Prescriptivist ideas are usually more about proving something about their holders than anything practical.
