Slice ripe peaches into thin wedges on a cutting board, watching their juices bead and drip onto the surface.
Bring water to a gentle simmer in a saucepan, then add the tea bags and steep for about 10 minutes, until the tea is deep in color and fragrant.
Remove the tea bags and stir in honey or simple syrup, blending until fully dissolved. Let the sweetened tea cool slightly.
Pour the warm tea over the sliced peaches in a large bowl or pitcher, then gently stir to coat the fruit in the fragrant liquid.
Allow the peaches to soften and release their aroma for about 10-15 minutes, stirring occasionally, until the fruit is tender and fragrant.
Once the peaches are soft, add freshly squeezed lemon juice and bourbon, stirring gently to combine all the flavors.
Fill glasses with plenty of ice, then ladle the bourbon peach tea over the ice, allowing the drink to chill quickly and develop a vibrant amber color.
Garnish with a peach slice or a sprig of mint if desired, and serve immediately for a refreshing, fruity beverage.
