This refreshing Grapefruit Tequila Sour has quickly become my go-to cocktail when I want a zesty yet smooth drink. The vibrant tang of grapefruit pairs beautifully with tequila, made extra special with a frothy egg white foam, and it’s a perfect balance of tart citrus and soft sweetness.

I first discovered this recipe while experimenting with citrus-based cocktails, and it quickly became a favorite for weekend get-togethers and special celebrations. The foam from the egg white takes it to the next level.

Ingredients

  • Blanco or reposado tequila: Adds depth and structure to the drink. Blanco provides a crisp base, while reposado adds a touch of smokiness.
  • Fresh grapefruit juice: Offers the natural zestiness that defines the cocktail. Be sure to use ripe grapefruits for maximum flavor.
  • Lemon juice or lime juice: Enhances acidity for a well-rounded taste. Opt for fresh juice whenever possible for the best results.
  • Simple syrup: Balances the tartness perfectly with a hint of sweetness.
  • Egg white: Optional but adds a luxurious foam that elevates the overall presentation.
  • Ice cubes: Essential for chilling the cocktail.
  • Club soda or sparkling water: Provides a lighter, fizzy option if desired.
  • Grapefruit wedge: Makes for a beautiful garnish and hints at the flavors inside.

How To Make Grapefruit Tequila Sour Cocktail

Scoop and Measure Ingredients:
Combine tequila, grapefruit juice, lemon or lime juice, simple syrup, and egg white (if using) in a cocktail shaker.
Dry Shake:
Shake the mixture without ice for 10 to 15 seconds. This step helps to create the signature foam if using egg white.
Add Ice and Shake:
Add ice to the shaker and shake again until the mixture is thoroughly chilled.
Strain and Serve:
Strain the cocktail into a chilled coupe or rocks glass, ensuring the foam sits atop for presentation.
Optional Topping:
For a lighter version, top the drink with a splash of club soda or sparkling water.
Finish with Garnish:
Add a wedge of grapefruit on the rim or floating in the drink for both decoration and an extra hint of citrus aroma.

One of my fondest memories is serving this cocktail during a summer evening barbecue. The grapefruit’s bright aroma paired beautifully with grilled dishes, and the foam from the egg white became a fun conversation starter.

Storage Tips

Since this cocktail relies on freshly squeezed juice, it’s best enjoyed immediately. If you need to prep ahead, you can mix the juices and syrup in advance, keeping them chilled in the refrigerator for a few hours. Shake with tequila and egg white (if using) when ready to serve.

Ingredient Substitutions

You can replace tequila with vodka for a milder taste or use mezcal for a smoky twist. Honey syrup can substitute simple syrup for a deeper, richer sweetness, and feel free to swap grapefruit juice with blood orange juice for a striking color variation.

Serving Suggestions

Pair this drink with light appetizers like shrimp ceviche or guacamole. Alternatively, it’s a refreshing choice alongside grilled chicken or fish tacos for summer dining.
