Japanese organic karigane (green kukicha stem) tea combined with flash freeze-dried organic blueberries. Fresh, fruity flavors deliver very low caffeine content in a healthy, slightly tart tea. Green teas have the least caffeine of all true teas. Classic green teas contain the highest level of antioxidants. Our special green teas have additional aroma and flavor components added to the leaf through flavorings, bits of fruit, essential oils, herbs, flowers and sometimes roasting.
