Some describe it as an after-dinner pleasure, others a sturdy wake-up call. Whatever your opinion, you can’t deny the Whisky Sour cocktail is one of the world’s most iconic and classic barroom innovations. But have you ever tried to make one yourself? Well, this Saturday, May 16 might just be your perfect excuse to test out your skills. World Whisky Day is upon us again and it marks the ideal occasion to bust out the barware and step into the cocktail kitchen. To help you from making a mess and wasting the good stuff, the team at Man of Many have put together the best Whisky Sour recipe you’ll find anywhere.
Almost all of us have heard the name Whisky Sour before, some may have ever given it a crack in the past, but the drink is making a serious comeback of late, and of course, it’s all Leonardo DiCaprio’s fault. In the early scenes of Quentin Tarantino Oscar-winning film Once Upon a Time in Hollywood, we see DiCaprio’s suave and stylish Rick Dalton settle into a bar seat with his good friend/stunt double Cliff Booth and a feverishly good looking Whisky Sour. It’s true, we see Dalton indulge in perhaps a few too many cocktails of varying poisons and palates, but the Sour is his go-to and it should be yours too. While we aren’t advocating you to start filling steins worth of cocktails as Dalton does, we do want to give you the tools to make the best Whisky Sour any at-home mixologist can.
What is a Whisky Sour?
A Whisky Sour cocktail is a bourbon-based mixed drink that is often referred to as a Boston Sour. According to Brian Petro of The Alcohol Professor, the cocktail dates back as far as the late 1790s, when Vice Admiral Edward Vernon of England began mixing a few ingredients together to serve his crew. Battling scurvy and malnutrition, Vernon apparently wanted a drink that not only combatted sea-sickness but would not heavily intoxicate sailors. His answer was to water the alcohol down with lemon or lime juice. For the British, it was gin and brandy, but by and large, the Americans loved their bourbon, and thus, the Whisky Sour recipe was born.
Obviously, things have changed a little since those days, but the foundations for how to make a Whisky Sour have stayed relatively the same. The cocktail made its first appearance in written word as a mention in Jerry Thomas’ 1862 manifest, The Bartender’s Guide, with the concoction becoming a staple of dive bars, cocktail spots and mixologist work-stations worldwide. It’s not quite as simple as an Old Fashioned or a Margarita, but the best Whisky Sour recipe rivals any drink on the menu.
Served: Shaken; on the rocks

What is the Best Whisky for a Whisky Sour?
For the traditional American-style Whisky Sour recipe, the cocktail calls for a sweet bourbon with light citrus notes and a touch of smoke. The natural sugars in bourbon allow the sharp flavour of the citrus to cut through clearly without being too overpowering. By using this spirit, you’ll avoid ending up with a Whisky Sour that is more sour than enjoyable.
