Sparkling wine lengthens wine-based amaro and a tiny walnut-liqueur measure over a bitters-soaked sugar cube. The ingredients are built directly in a flute, with gentle mixing preserving the bubbles.

Active preparation: 2 minutes
Ingredients
- 1 piece Raw sugar cube
- 2 dash Angostura aromatic bitters
- 30 ml Cardamaro wine-based amaro
- 2.5 ml Nux Alpina walnut liqueur
- 120 ml Chilled brut Champagne
Instructions
- Set the sugar cube in a chilled flute and wet it with the aromatic bitters.
- Add Cardamaro and walnut liqueur, then stir gently around the cube.
- Slowly pour in the chilled sparkling wine, pause if it foams, and give one gentle lift with the spoon.
