As other posters have stated, if you understeep this tea, it has no flavor; if you oversteep it, it becomes bitter. I am having the last cup of a 2 oz resealable envelope and it is bitter. I think it should have more of a pure blueberry flavor to it.
Another thing that may be bothering me and making the tea taste bad to me is that it includes maltodextrin. Granted, I’m sure it’s very little as it’s a part of the acai fruit powder, last ingredient on the list. But still, I’m sensitive to gluten and it’s probably enough to make it taste nasty and to stuff up my head like I have a head cold. If Teavana is actually concerned with health, they need to put a warning on their teas that include maltodextrin for those with food sensitivities/allergies. I never thought tea would have maltodextrin in it, but now I know better. I will not buy this tea again. And here’s a thought: what if fruit-flavored tea included only tea and fruit! They need to dump the additives; it’s eliminating teas that I will buy from them and for family members!
I checked Teavana’s website today, they do clearly show maltodextrin as an ingredient. I don’t recall seeing that before, but it is there. All the same, I can’t order this tea again until they ditch the maltodextrin.
