The scotch sour is a fantastic way to dress up Scotch whisky. It's a simple spin on the popular whiskey sour, and the basic recipe requires just two ingredients. This is one of the most delightful scotch cocktails you can mix up and its an entirely different experience with each new whiskey you choose to pour.

The interesting part of scotch sour recipes is that the majority skip the sweetener. That balance of sweet and sour is vital in the whiskey version, but not so much in this recipe. You can always add a touch of sweetness, a splash of soda, or even an egg white to complete the traditional sour formula if you prefer. It's also likely that the perfect mix will change from one whiskey to another.

In this recipe, don't go overboard on the lemon juice. Scotch is a bit touchier ​than other styles of whiskey and the goal here is to merely accent it with the bright citrus flavor.


  • 1 1/2 ounces Scotch whisky (blended)
  • 3/4 ounce lemon juice (fresh)

  • Save your really good scotch for sipping straight and choose a budget-friendly option for your scotch sour experiments.
  • Blended scotch is generally preferred over single malts for this cocktail because the milder, balanced flavor tends to work best with lemon. It really does not work well with heavily peated scotch or those with other dominant flavors.
  • Consider fresh lemon juice essential. The bottled varieties simply do not have the clean taste that scotch deserves. One lemon yields about 1 3/4 ounces of fresh-squeezed juice, so half a lemon should be about right.
  • If you prefer, stir this cocktail in the shaker for about 30 seconds. The ice dilution helps marry the two contrasting flavors, and it's still best when strained over fresh ice.

Recipe Variations

There are a few ways to make a scotch sour and which you choose is going to depend on the particular scotch you pour. If you find that the drink is a little too sour with one whiskey, experiment with these additives:

  • Add 1 teaspoon of sugar or a dash of simple syrup.
  • Add a splash of soda water, but avoid sweetened sodas.
  • To give the sour a foam and luscious mouthfeel, shake it with 1/2 ounce of egg white. Often, this addition is best with the sweetener.

How Strong Is the Scotch Sour?

The scotch sour is a very short drink, shaking up just shy of 3 ounces. Like many cocktails of this sort, the alcohol content is about half the bottling strength of the scotch. With an 80-proof whiskey, it weighs in at about 22 percent ABV (44 proof).
