The rum sour is a great way to spice things up if you’re bored of the usual gin sours. You could think of this as a take on the classic daiquiri.

What is Rum Sour ?
A rum sour is a twist on the classic gin sour, using rum instead of gin. It can be made with white, dark, or spiced rum and which version you get will vary from bar to bar. You could also compare the rum sour to a daiquiri, except a daiquiri has no egg white.
Here’s how to make your own rum sour at home. In this recipe I’ve used dark rum but feel free to substitute it for any rum you like.
Rum Sour Cocktail Recipe
- 2 oz dark rum
- 0.75 oz lemon juice
- 0.75 simple syrup
- 0.5 oz egg white
- In a shaker combine all ingredients plus ice. Shake very well.
- Strain into chilled coupe glass.
When is this drink best ?
I think the rum sour is a great late summer/early autumn drink. You’ve got the sweet, caramel and vanilla notes in the rum, smoothed over by the egg white, and this all turns the normally fun and wild rum into a more elegant, subdued drink. I think a rum sour works best in any setting you’d normally have a sour cocktail.
My thoughts on Rum Sour
I liked the rum sour, and I think a large part of that is the rum I used. It was dark rum, so it has some funky, sweet, caramel notes to it that work very well with the idea of an egg white sour. The sweet and sour balance is just right, as both the lemon juice and the syrup are 1:1 so this is a balanced drink.
Had this been made with spiced rum, I think the spicy notes would’ve been stronger because of the lemon juice. And in the case of white rum, this would’ve resembled a gin or vodka sour very closely, as white rum is far more subtle than dark or spiced rum.

Notes, substitutes, and tips
Feel free to use whichever rum you prefer for this cocktail. It doesn’t have to be top notch, but it should at least be decent. The egg, lemon, and syrup will cover up any weird flavors so you can experiment with different brands and ages.
