According to the NY Times, rosé is the new trendy wine, but only if it's Domaine Ott which sells for $30/bottle.
This is an example of what Paul Fussell, the author of Class, would call "prole drift." Yes some people think Class is out of date because it was written in the eighties, but the principles of class it lays out are timeless. Once such principle is that sweet drinks are low class.
The people drinking overpriced rosé are probabably the same people who think they are fashionable because they wear overpriced prole clothing from Juicy Couture.
