Unsatisfied with the number of reasons people have to hate rodents already, scientists at Japan's Hiroshima University have taught mice to be wine snobs
. After being trained to pick red wine over other kinds the mice were taught to distinguish between brands. From the article: "We examined performance of mice in discrimination of liquor odors by Y-maze behavioral assays. Thirsty mice were initially trained to choose the odor of a red wine in the Y-maze. After successful training (>70% concordance for each trained mouse), the individual mice were able to discriminate the learned red wine from other liquors, including white wine, rosé wine, sake, and plum liqueur."
