Yum! This is strong (well, just right) if you brew it for 7 minutes, so if you want a lighter taste I would go for 5 minutes. It is tart, and I couldn’t detect any sweetness (although it was quite hot at the time so that could have affected my ability to taste it). I added a packet of Splenda and it was like kool aid for grown ups! I think it’s much better cooled, and will try it sans sweetener and chilled next time.
