The History and Origins of the Whiskey Sour
The whiskey sour is a true classic, with origins dating back to the 1860s. The first known published recipe appeared in the 1862 book The Bartender’s Guide: How To Mix Drinks by Jerry Thomas, featuring the original ingredients of whiskey, lemon juice, sugar, and egg white for a richer texture. This cocktail forms part of the “holy trinity” of cocktails: spirit, citrus, and sugar, making it one of the oldest and most enduring cocktail types.
The whiskey sour is often called a “Boston Sour” when the recipe includes egg white foam, which adds a luxurious, creamy mouthfeel. But the core recipe has remained largely unchanged since its inception over 150 years ago.
Essential Ingredients for a Whiskey Sour
To make the perfect whiskey sour, you’ll need a few key ingredients:
- Whiskey (2 oz) – Bourbon is the most common choice for its sweet, oaky notes, but you can also use rye, Canadian, Irish, or even Buffalo Trace whiskey.
- Lemon juice (¾ oz to 1 oz) – Fresh lemon juice is essential for that signature tart flavour.
- Sweetener (½ oz to 1 oz) – Simple syrup is the classic, but you can also use maple syrup, Demerara syrup, honey, or a 2:1 sugar syrup.
- Optional: Egg white (½ oz to 1 oz) or a cocktail foamer, for a rich, creamy texture.
- Garnishes: Orange peel/slice/twist, cocktail cherry (maraschino), and a few dashes of Angostura bitters.
The standard 2:1:1 ratio (2 parts spirit, 1 part citrus, 1 part sweetener) is the most common, though some variations use a 3:2:1 ratio or different sweeteners. Nutrition-wise, a single serving of a whiskey sour contains approximately 193 calories, 14 grams of carbs, and 13 grams of sugar.
How to Make a Whiskey Sour: Step-by-Step
Making a whiskey sour at home is easy, with just a few simple steps:
- Add the ingredients to a cocktail shaker, starting with the egg white (if using) and dry shaking for 15-30 seconds to emulsify the air and create a frothy texture.
- Add ice and shake for 10-20 seconds until the shaker is frosted and thoroughly chilled.
- Double strain the cocktail into a rocks, Old Fashioned, lowball, or coupe glass (no ice if the drink is foamed to avoid the foam sticking).
- Garnish with an orange peel, cocktail cherry, and 2-4 drops of Angostura bitters.
The dry shake helps create that signature foamy top, while the double straining ensures a crystal-clear, polished appearance. Precise measurements are key for consistent results, so use a jigger or measure to avoid variations in the final product.
Tools and Glassware for the Perfect Whiskey Sour
To make a whiskey sour at home, you’ll need a few essential bartending tools:
- Cocktail shaker
- Strainer (Hawthorne or slotted spoon)
- Jigger or measure for precise ingredient amounts
- Ice
As for glassware, the whiskey sour is traditionally served in a rocks glass, Old Fashioned, lowball, or coupe glass. If the drink is foamed, serve it without ice to prevent the foam from sticking. Measuring your ingredients is crucial for consistent results, as the volume of a half-lemon can vary significantly.
Conclusion
The whiskey sour is a timeless cocktail that’s easy to master at home. With its perfect balance of spirit, citrus, and sweetness, this classic drink has remained a bartender’s staple for over a century. By following the essential steps and experimenting with different whiskey and sweetener variations, you can create a whiskey sour that rivals any you’d find at a high-end bar. Cheers!
