Fill your tea jug about a third of the way full of water and drop in your tea bags. Side aside.
In a large pot bring to a rolling boil the 3 cups water, 3 cups sugar, and the peach slices. Stirring consistently. Make sure all of the sugar is dissolved and remove from heat. Let it cool for a few minutes.
Next you can remove the peaches slices or leave them in if you wish. Pour your simple syrup into the tea jug and give it a good stir. Just make sure it has slightly cooled. You don't want to bust your tea jug.
Depending on the size of your tea jug, you may need to add more water to bring it to the top.
Next, take the tea jug outside, and find a really sunny space that receives direct sunlight. Set the jug in the sun for about 4-6 hours and let it do its thing.
Store in the refrigerator to keep it extra cool.
Fill a tall glass with ice, dispense tea to the top, garnish with fresh mint or an extra peach and enjoy!
