The Rob Roy is a cocktail consisting primarily of whisky and vermouth, 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.

I had little opportunity to drink this cocktail because its taste was very dry and strong. But today I had and reassessed this strong cocktail. As I had many opportunities to visit bars and I am used to "strong" and "dry" drinks. Now I can enjoy this cocktail, Rob Roy.

When I ordered last drink at bar, the owner bartender suggested that base whisky should have been rare bottle at backbar. I said "No! It is Mottaina (wasteful with rare cask)!" And finally he made this Rob Roy with current WHITE HORSE. The aroma was spicy and there's a hint of slight bitterness in the sweetness. Taste was also good. I like this cocktail.

The owner bartender told me e used "Talisker" for this Rob Roy. Thus I felt some strong power inside. Not easy to drink and its complicated and strong aroma may not be liked by everyone. But I like this!
