Combine water and sugar in a large saucepan; cook over medium heat, stirring constantly, until sugar dissolves. Add remaining ingredients, stirring until grape juice melts.
Pour mixture into freezer trays; freeze until firm, stirring several times during freezing process. Yield: 5-1/2 cups.
(While the recipe does not offer the option, I would think that one could use an ice cream freezer, following the manufacturer's directions.)
