> Wine is probably the most extreme example as there's a heavy push to equate fancy (expensive) with tasty but very often the 2 don't correlate.

I would say the poster you're replying to would agree. And while it's true that price is largely unrelated to quality for wine, in blind taste tests, professional sommeliers performing a blind taste test do significantly better than chance when it comes to determining grape variety and country of provenance.[1] Which is to say that there are subtle differences of flavor from wine to wine that are detectable. But again, this is far from saying that expensive wines are better than cheap wines.
