In a champagne flute, combine juice and champagne (I used ⅓ juice and ⅔ champagne). Top with a splash of raspberry liqueur, and garnish with raspberries and peaches.
Notes
I left out quantities for this recipe because the quantity of juice and wine should be to your preference. I would estimate that each 750 mL bottle of sparkling wine would require 1 generous cup of peach juice.
