Also known as tears in Spain and cathedral windows in Germany, legs are the rivulets of wine that have inched up the inside surface of the glass above the wine, then run slowly back down. Myth has it that the fatter the legs, the better the wine. This is not true. The width of legs is determined by the interrelationship of a number of complex factors, including the amount of alcohol, the amount of GLYCEROL, and the rate of evaporation of the alcohol and the surface tension between solids and liquids. But the most important point is this: Legs have nothing to do with quality. It is irresistible to point out that wines—like women—should not be judged by their legs.
