Via John Gruber (emphasis mine):
I, for instance, am absolutely convinced, on an intellectual level, that the whole concept of “super-premium vodka” is basically one big marketing con. Vodka doesn’t taste of anything: that’s the whole point of it. As such the distinction between a super-premium vodka and a premium vodka is entirelyone of price and branding. And yet, it works! The genius of Grey Goose was that it created a whole new category above what always used to be the high end of the vodka market — and in doing so, managed to create genuine happiness among vodka drinkers who spent billions of dollars buying up the super-premium branding. But if someone asks me what kind of vodka I’d like in my martini, I still care, a bit. And if I my drink ends up being made with, say, Tito’s, I’m going to savor it more than I would if I had no idea what vodka was being used.
What’s more, you don’t need to spend hundreds of dollars on first-growth Bordeaux for this to work. You just need to spend a little bit more than you normally do — enough that you consider it to be a special bottle of wine. That’s it! When you sit down and pop it open, probably with people you love, in pleasant surroundings, everything is set for a very happy outcome.
