Sushi study finds deception - The New York Times

I wonder how often wine is mislabeled? I marvel at the number of bottles and the range of prices in the grocery store, despite the movies such as Wine for the Confused with John Cleese show how most people can't tell the difference between two buck chuck and $100 Bordeaux, but they still pay $20 for a bottle to take to someones house so not be appear cheap.
