1/2 cup orange juice
1/4 cup lemon juice
3/4 cup Grand Marnier (any orange liquor will do)
1 bottle (750 ml) white wine
1 litter sparkling water (orange if available)
1 orange, sliced
1 lemon sliced

In a large pitcher, combine orange juice and slices, lemon juice and slices, Grand Marnier and wine; stir until well combined. Chill at least 1 hour or longer. Add sparkling water just before serving. Spoon some of the fruit into your glass, pour in the liquid, and serve.
