Sprinkle gelatin over 1/2 cup wine, and let stand 5 minutes.
Combine 1 cup wine, juice, and sugar in a medium saucepan; bring to a boil over medium-high heat. Remove from heat; add gelatin mixture, stirring until the gelatin dissolves. Place pan in a large ice-filled bowl; let stand 20 minutes or until thick but not set, stirring occasionally. Whisk the gelatin mixture to form small bubbles; fold in orange sections, grapes, and raspberries. Spoon gelatin mixture into a 5-cup decorative mold coated with cooking spray. Cover and chill at least 4 hours. Place a plate upside down on top of mold; invert mold onto plate.
