The Perfect Gin & Tonic

1. Fill a balloon glass with ice cubes. Stir with a barspoon* to refresh the glass.
   
2. Pour in 4 cl of Citadelle Gin.
3. Add 12 cl of Hysope Original Tonic Water. Stir again.
4. Garnish with a half slice of grapefruit and a sprig of rosemary on the top of the glass.
5. Serve with a bottle of Hysope Original Tonic Water next to the glass, if you want to lengthen your glass !

* Hysope's tip:

No barspoon with you ? A simple spoon will do the trick !
