The Whiskey Sour is the epitome of the Sour principle: whisky, lemon, sugar. Here, the smoky sweetness of the Bourbon meets the sharp acidity of the lemon, rounded off with a touch of sweetness. No frills, just balance. Perfect for those who don’t want to drink whisky neat but still want to taste its character. A drink that already feels familiar after two sips—and wins you over after the third.
And this is what you need for the Whiskey Sour
6 cl Bourbon Whiskey
3 cl freshly squeezed lemon juice
2 cl sugar syrup (1:1, sugar to water)
Garnish: orange zest or half an orange slice
This is what matters
The lemon juice must be fresh—no bottled, no concentrate. Bourbon with 40–45 % alcohol works best: too weak, and it loses character; too strong, and it overpowers the acidity. The sugar syrup should be thin (1:1) so it mixes instantly. If you like, add half an egg white before shaking—this makes the drink creamier and stabilises the foam. But beware: egg white needs more shaking time (20 seconds), otherwise it stays watery.
Variations
- New York Sour — Like the Whiskey Sour, but with a dash of dry red wine (e.g. Cabernet Sauvignon) floated on top of the finished drink. The wine forms a thin layer on the drink and gives it a slightly bitter, fruity depth. Perfect with smoky Bourbon varieties.
- Boston Sour — Here, a whole egg white is shaken with the drink, creating a creamy, almost velvety foam on top. Important: first shake the egg white without ice in the shaker (dry shake) to emulsify it, then add ice and shake again. Garnish: a few drops of Angostura bitters on the foam.
- Rye Whiskey Sour — Instead of Bourbon, this uses Rye Whiskey—spicier, sharper, with more pepper and spice notes. The drink becomes drier and more complex. Ideal for those who prefer it less sweet. Reduce sugar syrup to 1.5 cl to maintain balance.
Frequently Asked Questions
Can I use other whisky instead of Bourbon?
Yes, but the taste changes. Scotch whisky (e.g. a light blended) makes the drink smokier and drier, while a Canadian whisky tastes milder and sweeter. Rye whiskey adds more spice. Bourbon is the classic choice because its vanilla and caramel notes harmonise perfectly with the lemon.
Why does my Whiskey Sour taste watery?
Probably because you shook too little or too slowly. The shaker should fog up before the drink is strained. Too much ice in the glass or waiting too long before serving can also dilute the drink. Always use fresh ice and serve immediately.
Do I absolutely need sugar syrup?
No, but it dissolves better than granulated sugar. If you don’t have syrup, dissolve 1 tsp sugar in the lemon juice before adding it to the shaker. Honey or maple syrup also work but change the flavour—honey makes the drink more floral, maple syrup adds a caramel note.
Can I make the Whiskey Sour without egg white?
Yes, the original recipe does not include it. Egg white makes the drink creamier and gives it a nice foam, but it’s not a must. If you want to try it: half an egg white per serving is enough. The key is the dry shake (without ice) before the actual shaking, otherwise the egg white won’t emulsify properly.
