In a small saucepan, bring 4 cups hot water to a boil over medium-high heat. Remove from heat, add tea bags, and let steep for 5 minutes. Remove tea bags and discard. Add sugar to desired taste and stir until dissolved. Let cool to room temperature.
In a pitcher, combine sweetened tea, sparkling water, and orange juice. Serve immediately. Garnish with orange, if desired.
