According to Imbibe!, the Green Swizzle reigned supreme in the Caribbean from the late 1890s through the 1930s, before being dethroned by the Daiquiri #2. A Rum Swizzle made green by the addition of wormwood bitters (or crème de menthe, by some accounts), the recipe cited here originally appeared in a 1908 edition of the New York Herald.
