Wash the peaches very well, peel and discard the pit. Slice the peaches into small sized pices.
Add the sliced peaches to a saucepan along with water.
Bring the mixture to a simmer, then cover and cook in medium heat for about 15 to 20 minutes until peaches are cooked and soft.
Once the peaches are cooked, switch off the stove and add the green tea bags.
Steep the tea for about 2 minutes. Make sure not to steep for longer time, to avoid any bitter taste to the peach sweet tea that we are making.
Once the tea is steeped, discard the tea bags.
Mash the peaches using a potato masher.
Add sugar, lemon juice and mix well, then switch on the stove and simmer the mixture for a couple of minutes more so the sugar is well dissolved with the prepared peach lemon green tea mixture.
You may further mash the peaches while you are simmering the tea, if needed.
Once the sugar is dissolved, switch off the stove and allow the tea to cool down to room temperature.
You may check the sweetness of the tea at this time, and if needed you may add little more sugar (you may also use honey instead of sugar if you want to use natural sweeteners).
It is a good idea to add any sugar while the tea is still hot, because it will be difficult to dissolve the sugar easily once the tea is cooled.
Once the tea is cooled to room temperature, strain the mixture through a fine mesh strainer to remove the pulp of peaches.
You can use a spoon to press against the strainer to get the most of the peaches while filtering through the strainer.
Once the tea is filtered, chill the prepared tea in refrigerator and once it's chilled enough, add ice cubes to tea cups or glasses and pour the tea over.
Once ice cubes are added, serve immediately for best results!
