Whiskey Sour
A classic and balanced cocktail featuring whiskey (often bourbon or rye), fresh lemon juice, and simple syrup, garnished with an orange slice and a cherry.
What is this drink?
The Whiskey Sour is one of cocktail history's oldest and most enduring templates — a simple framework of spirit, citrus, and sweetener that has been adapted hundreds of times over. At its core it is whiskey (usually bourbon), fresh lemon juice, and simple syrup, shaken cold and strained into a rocks glass. When an egg white is added, it transforms into a silky, cloud-topped showpiece.
Why you'll love it
It strikes the perfect balance of warming whiskey richness, bright lemon acidity, and just enough sweetness to tie everything together. The optional egg white adds a gorgeous foam layer and a luxuriously smooth mouthfeel that makes the drink feel indulgent and impressive. It is approachable enough for whiskey newcomers but satisfying enough for enthusiasts.
When to serve
The Whiskey Sour works beautifully as a pre-dinner cocktail, at a dinner party, or as a bar staple on a night out. It is equally at home at a casual get-together as it is at a sophisticated cocktail bar. Its bright, citrusy profile makes it excellent in warmer months, but the whiskey warmth keeps it year-round.
Pro tip
If using an egg white, always dry shake first — shake without ice for 15 to 20 seconds to emulsify the egg white and create a stable, voluminous foam. Then add ice and shake again to chill. The dry shake makes the difference between a thin, watery foam and a thick, glossy, pint-glass-worthy cloud. Always use fresh lemon juice; the bottled version destroys the balance.
Bourbon Whiskey
Bourbon is the classic choice, bringing caramel, vanilla, and oak sweetness that marries beautifully with lemon juice and simple syrup. Its sweeter profile means less simple syrup is needed for balance.
Fresh Lemon Juice
The essential acid component. Freshly squeezed lemon juice brings vibrant, aromatic tartness with natural floral notes that bottled juice simply cannot match. The ratio of lemon to sweetener defines the entire balance of the drink.
Simple Syrup
A 1:1 sugar-to-water syrup that dissolves instantly into the cold shaken drink. It provides the sweetness needed to balance the lemon's acidity and soften the whiskey's alcohol punch.
Egg White (optional)
One egg white added to the shaker transforms the texture of the drink dramatically, creating a thick, silky foam on top and a smooth, almost creamy mouthfeel throughout. It is highly recommended for the full experience.
Swap Options
Swap bourbon for rye whiskey to get a spicier, drier sour. Use Scotch for a smokier, earthy version. Aquafaba (chickpea brine) works as a vegan egg white substitute. Try honey syrup instead of simple syrup for a floral, complex sweetness. Add a float of red wine on top for a New York Sour — one of the best variations of this classic.

Different ways to make this drink your own
New York Sour
Float a small pour of dry red wine — typically Malbec or Shiraz — over the back of a spoon onto the finished Whiskey Sour. The wine creates a dramatic crimson layer and adds fruity tannins that contrast beautifully with the creamy egg white foam.
Amaretto Sour
Replace bourbon with amaretto liqueur and reduce the simple syrup as amaretto is already sweet. The almond and marzipan notes create a richer, dessert-like sour that still benefits from egg white foam for texture.
Honey Whiskey Sour
Swap simple syrup for honey syrup (equal parts honey and hot water, stirred to dissolve). The floral complexity of good honey adds depth and warmth, making this version feel more artisanal and sophisticated.
Tools that make this drink come together
Cocktail Shaker
A shaker is essential for whiskey sours. First do a dry shake (no ice) to emulsify the egg white into a stable foam, then add ice and shake again hard to chill and dilute the cocktail to the right consistency.
Hawthorne Strainer
The coiled spring strainer fits over the shaker tin and holds back ice and any solid pieces of shaken egg white foam while allowing the liquid to pour cleanly through.
Fine Mesh Strainer
Double strain through a fine mesh sieve as well to catch any tiny ice shards and ensure the foam is perfectly smooth. This step separates a good Whiskey Sour from an exceptional one.
Can't Find These?
No cocktail shaker? Use a large jar with a tight-fitting lid — shake vigorously. Strain through a slotted spoon and then through a clean tea strainer as a substitute for the fine mesh strainer.
The right glass makes a real difference
Coupe Glass
A coupe glass is the most elegant choice for a Whiskey Sour, showcasing the beautiful foam top and the amber colour of the cocktail. Served without ice in a coupe, the drink stays cold from chilling in the shaker and the delicate foam sits undisturbed on the surface. It elevates the presentation from a casual drink to something truly special.
Alternatives
A rocks glass over ice is the casual, classic way to serve it — particularly if skipping the egg white. An old-fashioned glass gives a similar relaxed feel. A Nick & Nora glass works beautifully if you want elegance without a wide coupe bowl.
Perfect food pairings to complete the experience
BBQ Ribs
The sweet-and-sour profile of the Whiskey Sour cuts through the sticky richness of barbecue sauce, while the bourbon notes echo the smokiness of slow-cooked pork ribs.
Aged Cheddar
Sharp, crystalline aged cheddar has enough boldness to stand up to the whiskey's character. The creamy, salty cheese is refreshed by each sip of the bright citrus cocktail.
Caramelised Onion Tart
The savoury sweetness of caramelised onions mirrors the vanilla and caramel in bourbon, while the buttery pastry provides a rich counterpoint to the cocktail's acidity.
Pecan Pie
The nutty, molasses sweetness of pecan pie plays perfectly against a rye whiskey sour's spicy backbone. A classic dessert pairing that feels indulgent without being cloying.
Prep in advance for effortless serving
Pre-Mix the Sour Base
Combine bourbon, lemon juice, and simple syrup in a sealed bottle and refrigerate up to 24 hours ahead. When ready to serve, add the egg white and shake — first dry, then with ice.
Pre-Squeeze Lemons
Juice lemons several hours ahead and store in the fridge. Fresh lemon juice keeps its bright flavour for up to 8 hours, making it ideal for prep before a dinner party.
Separate Egg Whites in Advance
Separate egg whites up to a day ahead and store covered in the fridge. Cold egg whites whip into stable foam just as well as room-temperature ones when dry shaken vigorously.
Chill Your Glasses
Place coupe or rocks glasses in the freezer an hour before service. A chilled glass keeps the cocktail at the ideal temperature longer, especially important for a neat pour without ice.
