If desired, top with a dash of club soda. As a point of interest, agave nectar has a cleaner, lighter taste than honey and it also doesn't spike sugar levels as does honey. Now that I've got you hooked on agave nectar, go make recipe #453425.
In a saucepan, combine 6 cups cold water and bring to a boil. Remove from heat and immediately add the tea bags, orange juice, lemon juice and agave nectar. Cover and let stand for 30 minutes.
Remove the lid, allow the tea to cool and remove the tea bags with a slotted spoon. Do not squeeze bags; it makes tea bitter. Pour into a 1 gallon container, topping with the additional 6 cups cold water; stir.
To serve, ladle into tall glasses filled with ice and garnish with orange wedges or mint springs.
