The whiskey sour is a timeless cocktail with a rich history, dating back to the mid-1800s. First documented in the 1862 book “The Bartender’s Guide: How To Mix Drinks” by Jerry Thomas, this classic drink has remained a staple in the world of mixology for over 160 years.
Key Takeaways
- Whiskey Sour is a classic cocktail with a long history, dating back to the 1860s.
- The standard sour formula is a 2:1:1 ratio: 2 parts spirit, 1 part citrus, 1 part sweetener.
- Fresh lemon juice and simple syrup create a more balanced, complex flavour compared to pre-made sour mix.
- Adding egg whites to a whiskey sour results in a silky, luxurious mouthfeel and a distinctive foamy layer on top.

Perfecting the Classic Formula
The standard classic sour formula is a 2:1:1 ratio: 2 parts spirit, 1 part citrus, 1 part sweetener. For a whiskey sour, the basic recipe calls for 2 ounces bourbon whiskey, 1 ounce fresh lemon juice, and ¾ to 1 ounce simple syrup.
Fresh vs. Pre-Made: Choosing Quality Ingredients
A classic fresh whiskey sour uses fresh lemon juice and simple syrup for a balanced, complex flavour, creating a brighter, more refreshing drinking experience. In contrast, pre-made sour mix drinks are often overly sweet with limited depth of flavour, relying on artificial flavouring and representing a convenience trade-off for quality.
Elevating the Whiskey Sour with Egg Whites
Egg whites add a silky texture and luxurious mouthfeel to the drink, creating the distinctive foamy layer on top. Bartenders have been using egg whites in sours since the 1860s or earlier, with the “dry shake” technique incorporated to properly incorporate the egg whites. Egg-free alternatives like aquafaba (liquid from canned chickpeas) or commercial cocktail foamers can also be used to achieve a similar effect.
Conclusion
The whiskey sour is a timeless classic that has stood the test of time, with a rich history dating back over 160 years. By using fresh, high-quality ingredients and incorporating techniques like the addition of egg whites, you can create a bourbon sour that is both balanced and luxurious in texture and flavour.
