The five-time Grammy winner was a fan of a classic cocktail called The Stinger. This boozy beverage is made with Cognac, or "eau de vie" as the French call it, along with white crème de menthe.

The Grasshopper is known as the quintessential minty cocktail of the '50s, given its alarmingly green color and sweet menthol flavor, but the Stinger actually started it all back in the 1890s.
