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."
