Wash and slice the peach. Add the peach slices to a small bowl along with the ginger zest, and sugar. Stir to fully coat the peaches with the sugar and zest. Let the peaches sit for at least 20-30 minutes to macerate. (Macerate = let the sugar pull the juice out of the peaches. This will provide a sweet, delicious juice that will give the tea its flavor.)

In a small saucepan, add the 2 1/2 c. water and bring to a boil. Remove from heat. Add the tea bags, cover the saucepan, and let the tea steep. Let the tea come to room temperature. Remove the tea bags (don't squeeze the tea bags. This will release the tannin and make your tea bitter.)

In a 2-quart pitcher, fill the pitcher 1/3 full with ice. Add the peach mixture, along with any juices that were drawn out. Pour the tea concentrate over the ice and peaches and fill the pitcher with water. Chill at least 1 hour before serving.
