Verjus Orange Blossom Coffee Tonic

1. Build the Base

1. Fill a highball glass to the brim with fresh ice cubes.
2. Pour in 40ml white verjus and 2.5ml orange blossom water.
3. Top with 120ml tonic water and give it a single gentle lift with a spoon to combine the base without knocking out the carbonation.

2. Float and Finish

1. Gently pour 30ml of espresso directly over the top of the ice (or across the back of a spoon) so it sits suspended over the sparkling base.
2. Express the essential oils from the orange peel over the glass, rub it lightly around the rim, and tuck it neatly into the top of the ice.
