How this recipe comes together
Fill a glass with frozen water cubes to keep the drink cold and slow dilution. Pour blue curaçao syrup over the ice so it settles toward the bottom and creates a deep blue center. Top gently with cold grapefruit tonic. The bubbles lift the syrup slightly and create a soft, ocean-like effect. Stir very gently once, then garnish if desired.
This short process means no special tools are needed, just chilled ingredients and a careful pour.
What you’ll need
- Blue curaçao syrup (non-alcoholic)
- for color and sweet orange flavor
- Frozen water cubes
- large or clear cubes work best
- Grapefruit tonic water
- for citrus bitterness and carbonation
Substitution notes
- Swap grapefruit tonic for plain tonic plus a splash of fresh grapefruit juice if you want less sweetness.
- Use lemon-lime soda for a sweeter, softer citrus profile.
- For a lower-sugar option, choose diet tonic or sparkling water with grapefruit essence.
How to prepare it
- Choose a tall glass and fill it with frozen water cubes.
- Pour the blue curaçao syrup over the ice, aiming for the center so it pools near the bottom.
- Slowly top with grapefruit tonic water, pouring gently down the side of the glass.
- Stir very gently once or twice and serve immediately.
These short steps help keep the color contrast visible while maintaining fizz.

Common questions
How long does it take to make?
A: About 1 to 2 minutes once ingredients are chilled.
Will the layers stay separated?
A: Only briefly. Very cold ingredients and slow pouring help maintain contrast.
