#245 Cocktail: Rob Roy

    Created in 1894 by a bartender at the Waldorf Astoria in Manhattan, New York City. The drink was named in honor of the premiere of Rob Roy, an operetta by composer Reginald De Koven and lyricist Harry B. Smith loosely based upon Scottish folk hero Rob Roy MacGregor.
     A Rob Roy is similar to a Manhattan but is made exclusively with Scotch whisky, while the Manhattan is traditionally made with rye and today commonly made with bourbon or Canadian whisky.
