Finish up your weekend with glass of your favorite bourbon. And while you imbibe, these findings from researchers at the University of Louisville (because of course) will keep you company. A team from the school's department of mechanical engineering observed web-like patterns or "fingerprints" when a drop of American whiskey evaporated. The same characteristic isn't present in Scotch whisky or other liquors. What's more, each pattern was a unique indicator of both whiskey type and age.
