Perfect Rob Roy

The Perfect Rob Roy is an elegant variation of the classic Rob Roy cocktail, which is itself the Scotch whisky version of the Manhattan. The "perfect" in its name refers to the split base of vermouth, incorporating equal measures of both sweet Italian vermouth and dry French vermouth. This combination results in a beautifully balanced drink that is less sweet than the standard version but more nuanced than a Dry Rob Roy. It is an ideal choice for those who appreciate the complex interplay between Scotch and fortified wines.

Backstory

The Perfect Rob Roy emerged in the early 20th century, following the creation of the original Rob Roy in 1894 at the Waldorf Astoria in New York. Its invention is a logical progression from the "Perfect Manhattan," where bartenders began splitting the vermouth base to achieve a medium-dry profile. This popular technique was naturally applied to the Scotch-based Rob Roy, creating a new standard for those seeking a more balanced version of the drink.
Origin
United States, early 20th century. It is a direct variation of the Rob Roy (1894) and applies the "perfect" vermouth ratio popularized by the Perfect Manhattan.

Perfect Rob Roy

The name "Perfect Rob Roy" directly describes its composition. In cocktail terminology, "Perfect" signifies the use of equal parts sweet and dry vermouth. This distinguishes it from a standard Rob Roy (which uses only sweet vermouth) or a Dry Rob Roy (which uses only dry vermouth).

  • Blended Scotch Whisky60 ml / 2 oz
    A good quality blended Scotch is recommended to avoid overpowering the delicate vermouths.
  • Sweet Vermouth15 ml / 0.5 oz
    Also known as Italian or red vermouth.
  • Dry Vermouth15 ml / 0.5 oz
    Also known as French or white vermouth.

Mixing equipments

This is a stirred cocktail, requiring a mixing glass, a bar spoon for chilling and dilution, and a strainer to pour the finished drink without ice. A jigger is essential for the precise balance of ingredients.
  • Mixing glass for combining and chilling ingredients.
  • Jigger or measuring tool for accurate pours.
  • Bar spoon for stirring the cocktail.
  • Cocktail strainer (Julep or Hawthorne) to separate the ice.

Instructions

The process involves chilling the glass, combining all liquid ingredients in a mixing glass with ice, stirring until perfectly chilled, and straining into the glass. The final step is garnishing with a lemon twist to add aromatic oils.
1. Place your coupe or martini glass in the freezer to chill for at least 10 minutes.
2. Add the Scotch whisky, sweet vermouth, dry vermouth, and Angostura bitters to a mixing glass.
3. Fill the mixing glass two-thirds full with fresh, cold ice cubes.
4. Stir gently with a bar spoon for about 20-30 seconds, until the outside of the mixing glass is frosty.
5. Using a cocktail strainer, pour the drink into your chilled coupe glass.
6. Take a strip of lemon peel, twist it over the drink's surface to release its oils, and then drop it into the glass as a garnish.

Garnishing

A lemon twist is the classic garnish, as its bright citrus oils complement the complex flavors of the drink. Alternatively, a high-quality maraschino cherry can be used for a touch of sweetness.
  • Lemon Twist: Express the oils over the surface of the drink for aroma, then drop it in.
