The Whiskey Sour is the bourbon version of the sour template (spirit + citrus + sweetener + optional egg white), possibly the most-influential cocktail format ever invented. Half of the modern cocktail canon is a Whiskey Sour with the bourbon swapped for something else.
Ingredients
- Bourbon 50ml
- Fresh lemon juice 25ml
- Simple syrup 15ml
- Egg white 15ml (about half a small egg)
- 3 dashes angostura bitters to garnish
Method
- Dry shake, all ingredients except bitters, no ice, 10 seconds. This emulsifies the egg white.
- Add ice. Shake hard for another 10 seconds.
- Double-strain into a chilled coupe. The foam should sit clean and silky on top.
- Drop 3 dashes of angostura on the foam in a triangle. Drag a toothpick through for the classic decorative lines.
Why dry shake first
Egg white needs to denature and emulsify before ice enters the picture. Cold slows the reaction. A dry shake first builds the foam structure; the second shake with ice chills and dilutes.
Skip the dry shake and you get a thin foam that collapses within a minute. With dry shake, the foam holds for the full drink.
Why bourbon, not rye
Bourbon's vanilla-and-caramel character matches the sweet side of the sour balance. Rye works (and makes a more aggressive, drier sour) but bourbon is the canonical choice. Recommended bottles: Buffalo Trace, Wild Turkey 101, Four Roses, Maker's Mark.
Variations
New York Sour: add a float of red wine on top (gently poured over the back of a spoon). The wine layer adds tannic-fruity depth.
Gold Rush: swap simple syrup for honey syrup. Richer, more autumnal.
Penicillin: add ginger syrup and an Islay scotch float. Modern classic.
Kopi Sour: add 15ml cold-brewed kopi-O. Our Malaysian version. See Kopi Sour.
Egg-free version
Skip the egg white entirely, or substitute aquafaba (chickpea brine). The drink is less silky but still works. Vegans and people uncomfortable with raw egg both appreciate the option.

Frequently asked questions
What glass is the Whiskey Sour served in?
A chilled coupe. The dry shake (no ice, 10 seconds) emulsifies the egg white; the wet shake (with ice, 10 seconds) chills and dilutes. Double-strained up so the foam sits clean on top. Three angostura dashes go on the foam in a triangle, dragged with a toothpick for the classic decorative lines. A rocks glass over fresh ice is the alternative; both are correct.
Can I substitute the bourbon in a Whiskey Sour?
Rye works and makes a more aggressive, drier sour. Bourbon is the canonical choice; the vanilla-and-caramel matches the sweet side of the sour balance. Buffalo Trace, Wild Turkey 101, Four Roses, Maker's Mark all work. Aquafaba (15ml chickpea brine) substitutes for the egg white; slightly less silky but functional. Fresh lemon is non-negotiable. Honey syrup turns it into a Gold Rush; cold-brewed kopi turns it into a Kopi Sour.
How strong is the Whiskey Sour?
Around 18 to 22 percent ABV in the finished drink. The build is 50ml bourbon (around 40 percent) against 25ml lemon, 15ml syrup, and 15ml egg white, shaken with ice dilution. The egg white softens spirit perception and the citrus keeps it dry. Drinks easier than the alcohol number suggests; this is the defining template-based cocktail, designed for accessible session drinking.

Versatile across most dinners. Strong with grilled meats, BBQ, fried chicken, smoked salmon. Also good with hard cheeses and charcuterie. The acid cuts through fat and the foam softens spice. Pairs with most Southeast Asian food except for very delicate fish; the bourbon body handles satay, beef rendang, and mamak grilled items. Skip with delicate raw sashimi.
