Prep the Glass: Take a large wine glass or a highball glass and fill it to the top with fresh, solid ice cubes.
Add the Aromatics: Pour the elderflower syrup, rose water, and fresh lemon juice directly over the ice.
Top with Tonic: Slowly pour the premium tonic water into the glass. Pouring it slowly down the side of the glass helps preserve the crisp carbonation.
Gentle Lift: Insert a long bar spoon to the bottom of the glass and give it a single, gentle upward swirl to blend the floral syrups with the tonic without destroying the bubbles.
Garnish: Drop a few dried culinary rosebuds onto the surface foam and weave a thin cucumber ribbon into the ice for a refreshing aromatic contrast.
