The quick answer is "no, it doesn't, nothing does":

The better answer emerges if you think about the example a little more closely. The big power law brands driven by customer appreciation are in media -- people love Lady Gaga (say), so she sells gazillions. Nobody loves yellowtail or sutter home. Many people love Screaming Eagle or Chateau Lafite. However, wine is an agricultural product; you cannot produce more bottles of a great wine than you can grow in some very particular fields in a year. The way scary hit-driven industries work is that you sell things way above marginal cost to everyone who wants them; in wine, since there's actually scarcity, very few people who love a brand can get as much as they want of it, so the prices at the top are insane (recent vintage screaming eagle is indicated at $2-3k per bottle), but the brands are smaller.
I'd guess the way to think of it is like the music industry before recording devices or electricity -- sure there are stars, but because supplies are limited nobody can by a megastar.
