Price is only weakly correlated with taste and quality and there are lots of $10 bottle of wines that are superior to lots of $30 bottles of wines. That being said, if I was offered pairs of randomly selected wines from the same grape and region, one costing $10 and the other $30, I'd like to think I'd pick out the $30 wine with a better random success rate. That being said again there is no reason to assume that one would necessarily always prefer the $30 bottle to the $10.
However at the price ranges we're talking about here you're not simply paying for taste. You're paying to drink something that is rare and in some way unique and/or interesting.
