In a large pot, bring the water to a boil. Steep the tea bags and fresh mint in the hot water. Remove the mint after 3 minutes, but continue to steep the tea until it is very dark. Remove the tea bags. Add the sugar and juices while the tea is still warm. Stir to dissolve the sugar. Pour into a gallon container (large mayonnaise jar) and add water to fill. Refrigerate. Serve with ice and garnishes.
