Pour 4 cups boiling water over tea bags; cover and steep 5 minutes. Remove and discard tea bags. Stir in sugar and juice concentrate, stirring until sugar dissolves. Cover and chill 2 hours.
Stir together chilled tea mixture and sparkling wine. Serve immediately.
Refreshing and a nice twist on Mimosas. Great brunch drink or with appetizers before a family meal. Plan on serving this before Thanksgiving dinner this year.
