A retired professor and statistician who also happens to be a small vintner, Robert Hodgson, decided to unmask the dog and pony show that is wine judging in America. It doesn't appear that he has made a lot of friends.
Hodgson would put the same wine in different bottles at the same competition and get wildly different scores from the very same judges and critics. He did some other crafty things as well. The California State Fair Wine Competition judges tried to suppress his findings for years but they were published earlier this year in the January Journal of Wine Economics.
Turns out that judging wine is about as subjective and accurate as random coin flipping. One snob's hint of currants and pear is apparently another man's asphalt emulsion and turnip salad. Some interesting cover your ass reactions from wine luminaries like Robert Parker. Send this very interesting read to the wine snobs in your life.
