The vodka sour

After the dry martini, the sour family of cocktails is one of the first sets of classic cocktails that a home bartender should master. They are easy recipes for great cocktails with a perfect balance between sweet and tart.

You can take the sour formula and change it up by using a different base liquor. Make your sour with rum and lime juice, and you have a daiquiri. Change it to tequila and Cointreau, and that’s a margarita. Make it with gin and lime juice, and it’s a gimlet.

You can turn a vodka sour base into a highball cocktail with some bubbly water. Add soda water and you’ve got a Vodka Collins. Add tonic water and it’s a Vodka Tonic.


The basic formula for the vodka sour is two ounces of vodka, three quarters of an ounce of fresh lemon juice or lime juice, and three quarters of an ounce of simple syrup. You can, of course, make it sweeter or more sour depending on your preference.

The egg white was not included in the original sour cocktails, which date back to the 1800s. Leave it out if you’re concerned about foodborne illness. Or keep it in if you want that frothy topping no matter what.

Variations and substitutions

  • Skip the egg white and add soda or tonic water for a blackberry vodka soda or blackberry vodka tonic.
  • Change up the flavor in this classic cocktail with any other homemade simple syrup.
  • Garnish with a lemon slice, lemon twist, or maraschino cherry.

Recipe tips and tricks

How to make a vodka sour

Tips from the wise quacker: the vodka sour is a shaken cocktail. If you want to include the optional egg white in your blackberry vodka sour, the key to getting the layer of foam is the dry shake method. Doing a dry shake allows you to create a foamy top without diluting your cocktail.

First, add the cocktail ingredients to your cocktail shaker without any ice and shake. Hold it tight, because the pressure is going to build up in your shaker! After about 10 to 20 seconds or so, add a half cup of ice cubes to the shaker, shake, and strain.

You can serve this up in a chilled coupe or other cocktail glass. Or serve it in a rocks glass with a large ice cube.

Cocktail FAQs

What’s the best vodka for a vodka sour?

You can use any type of vodka for a vodka sour, but it’s best to choose a vodka that is smooth and clean-tasting. I make our vodka cocktails with Ketel One, but there are lots of great options.

Can I use bottled lemon juice for a vodka sour instead of fresh?

I always recommend fresh lemon juice when making cocktails, but you can use bottled lemon juice in a pinch. Be sure to check if your bottled lemon juice is concentrated, and keep in mind that bottled lemon juice may have a slightly different taste than fresh.

What is the likelihood of getting sick from the raw egg white?

I cannot give you a probability. Please use your personal judgement, because consumption of raw eggs may result in foodborne illness.The original sour recipe had no egg white, so you can omit it if you are concerned about raw egg whites. If you can find them, you could use pasteurized egg whites or a tablespoon of aquafaba.
