IMHO, there are two price bands for wine: under-$10, and over. I have an unsophisticated palette, but I can tell a cheap wine from a not-cheap one. I can't tell a not-cheap one from an expensive one, though. Some really expensive wines taste like crap to me, worse than the mid-range ones. That's the only time I can pick out on expensive wine: it might taste bad, but it doesn't taste cheap.
