Unsure how to rate this. I have made it 3 or 4 different times, and each time I primarily just taste warm water with a hint of green tea, and a bitter earth flavor that I can only assume are the berries. Odd, since the ingredients state this blend does have blueberries in it, which should have added some sweetness? I steeped it a bit longer than it called for, still not much difference in the results. Maybe it’s just not for me.
