Chop up the medjool dates into small pieces, as small as you can get them. Place your dates, nectarines and water into a pot, and heat until boiling. Bring the heat to low and use a wooden spoon to stir and mash the nectarines and dates a bit to infuse the flavor.
When the sugar is dissolved, cover your pot and remove from heat. Set it aside for at least 30 minutes.
Now grab a larger pot and brew your tea. Bring your water to a boil and add the tea bags for 4.5 minutes, 5 minutes max.
Remove the tea bags and transfer to a pitcher that you can place in the refrigerator to cool.
Strain your simple syrup into a bottle or container (you can save the nectarines for later use).
Once cooled, combine the simple syrup and tea into a large pitcher. If using basil, combine the basil in as well and allow it to infuse for at least an hour.
Serve in individual glasses over ice with fresh sliced nectarines and more basil if desired.
