Fill a pitcher with a few cups of ice and the grapes, and sliced orange and lemon or lime. Add the orange juice, vodka, agave or simple syrup, orange juice, and sparkling wine or water. Pour in the hibiscus tea. Stir well to combine. If not totally cold, chill for 2 hours.
Serve in glasses with ice and some of the fruit from the pitcher.
Notes
You can juice any oranges you have, from plain old juice oranges to clementines to blood oranges. If all you have is packaged orange juice, that will work in a pinch.
