At the peril of being annoying long after the fact, I did read the post, and he does have a point that's a little deeper than your rejoinder: wine does not have the competition-destroying superstar effect we see in categories with less constrained supply. Your examples are not comparable to the kind of market position the players mentioned in the original post have. The favorite brands do not drive out the smaller players. Is that a "power law" or not, well, hard to say; if it's purely size-based, sure, but if we're talking about the way that a big brand dominates a market, no, there is no such thing in wine.
