In a large pot, bring 4 cups of water to a low boil. Once boiling, remove from heat.

Add the tea bags, cover, and let steep for 5-7 minutes, depending on how strong you like your tea.

Combine the sliced peaches, sugar, and 1 cup of water in a saucepan over medium heat.

Cook until the sugar has dissolved and the peaches have softened, about 5 minutes.

Use a wooden spoon to gently mash the peaches and release their flavor.

Remove the tea bags from the tea and discard.

Strain the peach mixture through a fine mesh strainer into the pitcher of tea. Press on the solids to extract all the juice.

Add lemon juice to the peach tea and stir well.

Chill in the refrigerator until cold, at least 1 hour.

Fill glasses with ice cubes.

Pour the cool peach tea over the ice.

Garnish with mint leaves and a slice of peach or lemon, if desired.
