Tart is the word! I liked this tea, but did not LOVE it… a bit too tart for me. Next time I will add some rock sugar to it and maybe that will bring the tartness down a bit. I really like that its a mate, because sometimes I just need an extra kick in the day. This tea might taste really good iced, but I have only had it hot. Glad I have it, but also glad I only got 30g of it. I feel that that will be enough for me.
