Full Ingredients
For the Salt Rim
- 1 tablespoon kosher salt
- 1 small wedge cut from a pink or ruby red grapefruit
For the Cocktail
- 2 ounces gin or vodka, chilled to 40°F or below
- 4 ounces freshly squeezed pink or ruby red grapefruit juice, chilled to 40°F or below
- 1 cup standard ice cubes, divided
For the Garnish

Step-by-Step Instructions
Step 1: Chill the glass
Place one 10- to 12-ounce rocks or highball glass in the freezer for 5 minutes. A cold glass helps the Salty Dog stay crisp and refreshing without requiring extra ice, which could dilute the grapefruit flavor.
Step 2: Prepare the grapefruit juice
Squeeze a pink or ruby red grapefruit until you have exactly 4 ounces, or 1/2 cup, of juice. Strain the juice through a fine-mesh strainer if you prefer a smoother cocktail, or leave a little pulp for a more rustic texture. Keep the juice refrigerated at 40°F or below until needed.
Step 3: Make the salt rim
Spread 1 tablespoon kosher salt in an even layer on a small plate. Run the cut side of the grapefruit wedge around the outside edge of the chilled glass, moistening about 1/4 inch of the rim. Dip the rim into the salt and turn gently until evenly coated. Try to keep most of the salt on the outside of the glass so it seasons each sip without falling into the drink.
Step 4: Combine the cocktail
Pour 2 ounces chilled gin or vodka and 4 ounces chilled grapefruit juice into a cocktail shaker. Add 1/2 cup ice cubes. Secure the lid tightly before shaking.
Step 5: Shake until cold
Shake the cocktail firmly for 10 seconds. The shaker should feel frosty on the outside. This quickly chills the ingredients to approximately 35°F to 40°F while adding just enough dilution to soften the grapefruit’s natural acidity and bitterness.
Step 6: Strain and garnish
Add the remaining 1/2 cup ice cubes to the salt-rimmed glass. Strain the cocktail over the fresh ice, taking care not to splash or disturb the rim. Garnish with one thin grapefruit half-wheel or small wedge and serve immediately.
Pro Tips
- Use freshly squeezed grapefruit juice whenever possible. Bottled juice may taste sweeter or more bitter depending on how it was processed.
- Moisten only the outside edge of the glass before salting it. This gives you a controlled hint of salt instead of an overly salty drink.
- Choose gin for a more aromatic cocktail with botanical notes, or vodka when you want the grapefruit to be the dominant flavor.
- Large, dense ice cubes melt more slowly and help prevent the drink from becoming watery.
- If your grapefruit is especially tart, stir 1 teaspoon simple syrup into the shaker before adding the ice.
Variations
- Spicy Salty Dog: Mix 1/8 teaspoon cayenne pepper or chili powder into the tablespoon of kosher salt before rimming the glass.
- Sparkling Salty Dog: Use 3 ounces grapefruit juice instead of 4 ounces, then top the finished cocktail with 1 ounce chilled club soda.
- Rosemary Salty Dog: Gently bruise one 3-inch rosemary sprig, shake it with the spirit and grapefruit juice, then strain thoroughly before serving.
Storage & Make-Ahead
For the best flavor and texture, prepare and serve the cocktail immediately after shaking. Fresh grapefruit juice can be squeezed, strained, and refrigerated in an airtight container at 40°F or below for up to 24 hours. You may also measure and combine the spirit and grapefruit juice up to 4 hours ahead; refrigerate the mixture without ice, then shake it with ice just before serving. Do not store a finished cocktail over ice because it will become diluted. Prepare the salt rim no more than 15 minutes before serving so it remains dry and neatly defined.
