It seems that wine sales are up yet again this year, and especially so among younger adults. This is especially striking given these numbers from this article:
The number of U.S adults who call themselves wine drinkers has risen 53 percent since 2000, from 49 million to 75 million. Over the same period, the number of people who said they drink alcohol — but not wine — dropped 13 percent, Gillespie said.
The article then goes on to say that if this trend continues the market for wine will continue to expand.
Given the resurgence of interest in fine food, and the celebrity chef phenomenon, I would think that greater gains will be made in the future, even despite the economy.
