Bring the water to a boil in a large pot. Turn off heat. Add tea bags and steep for 5 to 10 minutes. Allow to cool.
Add 12-ounces of the peaches to a blender and puree until it reaches a smooth consistency.
Combine the cool tea, peach puree, peach nectar, peach liquor and remaining slices of peaches to a glass pitcher. Serve over tall glasses of ice with a sprig of mint to garnish.
