In a small pot, combine the sugar and water. Bring to a rapid boil. Remove from heat, and stir in the rhubarb. Allow to cool down to room temperature. Transfer to a small bowl and chill in the fridge for at least 30 minutes.

In a large pitcher, combine orange juice, fresh strawberries, cooled rhubarb syrup, ginger ale, white wine, and ice. To serve, ladle into tall glasses with ice. Add a lime slice and a sprig of fresh mint. Enjoy!
