This tea is actually pretty good if you do not abuse it too much.
The bag contains black, green and oolong tea, which makes for a strange brew time. The bag (I do not have a box) does not give any indication of how long it should be infused, so I played around with the few bags.
First, infusing hot, no additives, three minutes. Pretty good, light on all three flavors, but mostly a sweet clean green with a base note of black tea with the final mouthfeel-taste of oolong.
Second, infused hot, no additives, five minutes. Starting to get a little bitter, not really the best, can still pick up the green and oolong while the black plays a background note.
Third, infused hot, no additives, seven minutes (strictly because I forgot about it). Really super bitter, overpowered all flavors except the black tea.
The final verdict: this tea is decent if infused 3-5 minutes. It does not need anything added to make it taste good and be able to pick up on all three flavor teas. The brew is very good, especially for my morning cuppa on my way to work.
