Start with simple syrup. Boil sugar and water in a small sauce pan (small pot). Once it comes to a boil, and sugar completely dissolves, turn off the heat. Set aside.
Bring 3 quarts (12 cups) of water to a boil. Turn off the heat, add 5 green tea bags into the pot and let them sit for 5 minutes. After 5 minutes, discard the tea bags and let it cool.
Add 1½ pints of blueberries into a food processor or a blender. Save ½ pint for garnish. Blend until you no longer see the chunks.
Pour the blueberry puree through a strainer. Use a spoon to push it through.
Add simple syrup into the tea. Followed by strained blueberry puree. Stir to combine.
Refrigerate and chill for at least 1 hour. Serve over ice and garnish with fresh blueberries (the ½ pint that you save) and some fresh mint.
