Rob Roy
The Rob Roy is the Scotch whisky version of the Manhattan and is sometimes referred to as a Scotch Manhattan. It was named after Robert Roy MacGregor, the Scottish Robin Hood of the 18th century.

Like the Martini and Manhattan, the Rob Roy can also be made dry or perfect. Dry would use dry vermouth, while perfect would use equal parts sweet and dry vermouth. See more about this below. (Spirits/Cocktails)
