✔ Lillet Blanc (5 cl)
✔ Schweppes Original Wild Berry (10 cl)
✔ Raspberries and/or strawberries
✔ Ice cubes

Alcohol-free variant, instead of Lillet Blanc:
✔ lime juice (3 cl)
✔ sugar syrup (2 cl)

Pour Lillet Blanc (non-alcoholic version with lime juice and sugar syrup) into a wine glass, fill with ice cubes and top with Schweppes Original Wild Berry. Add quartered strawberry and/or raspberries and stir gently.
