Nah, you're not wrong. As a bit of wine nerd, I've never heard other wine nerds care too much about how expensive a wine is. What they care about, and love talking about, is geography and grapes and production methods. Now some of those factors do correlate with price, but everybody is very aware that a lot of expensive wine is pure marketing, and that some producers are able to make wines that punch far above their weight, price wise.
