Wine Snobs: Justified by Science, Sort Of

Wine Snobs: Justified by Science, Sort Of
Have you ever described a wine as "chewy"? Have you ever swirled that wine in a glass, then plunged your nose into the bowl to take in the bouquet? Have you ever examined a wine's legs? I have done two of the three of these things, which means, basically, that I am two-thirds of an enormous jerk. But I am also, in my way, a bold sojourner into the field of scientific inquiry. Because wine snobbery has a purpose, and that purpose is science.

Dan Quinn is a graduate student at Princeton who studies fluid mechanics. He made the video below, which explains why wine, when it's swirled, clings to the glass that contains it, then drips back down to gorgeous and occasionally hypnotic effect. The wine's Chihulian appearance has to do, basically, with liquid's surface tension. And with evaporation. And with gravity.
