Boil 3 cups filtered water in a pot over medium heat. Remove from heat and add the teabags. Let steep 30 minutes.
Bring to a boil 2 cups filtered water, 2 cups of sugar, and green coffee bean powder in a medium pot over medium-high heat, stirring to dissolve the sugar.
Remove from the heat and add the ginger. Let steep for 30 minutes.
Pour through a fine sieve and discard the chunks of ginger.
Remove tea bags from the steeped tea and pour into a 2 quart pitcher.
Add the ginger simple syrup and the two cups of white grape juice and mix.
** I prefer substituting filtered water for the grape juice as the juice makes the drink very sweet.
