Lemmings to the Sea?

A few years ago I was in Napa and stopped by the Dean & DeLuca store. In perusing through the myriad of wine racks, I was taken by the Cabernet Sauvignon section. It was huge! I was struck by not only how many bottles were priced at $100 or up, but how many I had never heard of. In the latter category, I counted 20 or 30 and gave up. As I left the store, I could not help thinking “This has gone too far. How many people are there to support the market?” It looked like a market top.
