Peel peaches if desired (I didn’t peel mine) and cut into slices.
Place the peach slices in a blender and blend until completely pureed. You should have about 2 cups of peach puree.
Combine bourbon, tea, lemon juice, sugar and peach puree in a zip top freezer bag or other freezer safe container and stir to mix well.
Place in the freezer for 8 hours or overnight to freeze.
Fill 4 glasses evenly with the frozen bourbon mixture and top with ginger ale to taste.
