For an alcohol-free, equally refreshing drink, use ginger ale instead of wine.
Makes about 7 cups
2 cups pineapple juice
1 cup pink grapefruit juice
2 tablespoons honey
1 tablespoon minced fresh ginger
1 (750-milliliter) bottle sparkling white wine, chilled
Garnish: pink grapefruit slices
Stir together first 4 ingredients in a large container; cover and chill at least 1 hour. Pour mixture through a fine wire-mesh strainer into a pitcher, discarding ginger. Add wine just before serving. Serve over ice. Garnish, if desired.
