Place all of the ingredients except the tea bags in a large saucepan or pot. Bring to a boil over medium-high heat. When the mixture comes to a boil, reduce the heat to medium-low, cover the pot, and simmer for 15 minutes. Add the tea bags, remove the pot from the heat, and let steep, uncovered, for 5 minutes. Pour the mixture through a fine-mesh strainer, reserving the liquid for use as concentrate and discarding the spices. Cool the mixture to room temperature, and then cover and refrigerate. You may use right away, although the flavors develop upon resting overnight.
