This is a very cool party cocktail. Be sure to add the remaining grapes at the very last minute, advise the editors of “1001 Cocktails” where I found the recipe, “then watch them liven up your drink as they jump around, making even more bubbles.”
Pink Champagne or other pink sparkling wine
5 or 6 red or black grapes
Splash of mandarin liqueur
Put aside two grapes. Crush or muddle the others in a small bowl to let the juice flow. Add ice and liqueur, stir well, then strain into a chilled Champagne goblet. Top up with Champagne. Cut the remaining grapes in half, remove the seeds, then add them to the glass just as you're ready to serve and enjoy the show.
