Dry this smells intensely of lime. Hot it is lime, lemon, and ginger. Once it cools it becomes more ginger, lemon/lime. The ginger packs some heat. I still don’t know what green rooibos tastes like. It seems to fill in all the flavor voids in the cup. I think I most detect it as a sweet grassy aftertaste. There is licorice root in this. It only adds a tiny amount of sweetness. Halfway through the cup I added a little sweetener to see how it would react. No problem, though it added nothing but sweetness. It is not something I would drink much of, but I can see this being fun for fans of lime and ginger.
