Iced and Refreshing Coffee
Grapefruit Espresso Tonic
Quick answer
Grapefruit juice adds acidity and bitterness to tonic, while espresso brings a roasted or fruity coffee note. The balance depends on the juice and tonic you use. Taste each on its own first; if either is strongly bitter, the combined drink may need a gentler coffee profile.
Key takeaways
- Grapefruit juice adds acidity and bitterness to tonic, while espresso brings a roasted or fruity coffee note.
- Combine the juice and tonic over ice, then slowly add cooled espresso as the method describes.
- Chilled ingredients and a cold glass slow melting and help the tonic stay lively.
Ingredients
- 40 ml cooled espresso
- 120 ml tonic water
- 30 ml grapefruit juice
- 120 g ice.
Method
- Combine juice and tonic over ice.
- Slowly add the espresso and stir once gently.
Pour without losing carbonation
Combine the juice and tonic over ice, then slowly add cooled espresso as the method describes. Stir once gently so the flavors meet without driving off all the bubbles. Fresh juice can vary in acidity, so use the listed amount first and adjust only in another serving.
Serve the drink cold
Chilled ingredients and a cold glass slow melting and help the tonic stay lively. Serve soon after assembly. If the drink is too tart, try a sweeter tonic or less grapefruit juice next time rather than adding sugar without measuring. For the simpler base, see classic espresso tonic.
Choose grapefruit juice by taste
Grapefruit juice varies in sweetness and bitterness. Taste it before combining it with tonic and espresso. The listed amount gives the drink a clear citrus presence; if it overwhelms the coffee, reduce the juice in another serving rather than changing the espresso and tonic together.
Keep the tonic lively
Pour slowly and stir only once so the carbonation remains noticeable. Use cold ingredients and serve promptly. If the finished drink tastes too bitter, try a different tonic or espresso on the next attempt; grapefruit, tonic, and coffee each contribute their own bitter notes.
Keep the drink’s layers distinct
Pouring the espresso slowly over the juice and tonic gives the glass a layered look. Stirring mixes the flavors but releases some carbonation. Either serving style works; choose based on the texture you prefer. Use a chilled glass and serve promptly so the ice does not dilute the grapefruit and tonic.
A tip for serving
Taste the grapefruit with the tonic before adding coffee. Both can taste bitter; use less juice next time if the combination feels too sharp.
