Ugh...orange pu-erh sounds awful. Regular aged pu-erh is pretty good but can be a acquired taste. Someone says it tastes like a barnyard. I think it tastes pretty pleasant and reminds me of the wet leaves smell of a forest after it rains. I've had some foul pu-erh that tasted like scummy pond-water. So YMMV.
I don't really understand the whole thing with fruit-flavored teas. If you want strawberry flavored tea, why not just drink strawberry juice? For me, tea has such a distinct flavor on its own, it's kind of a waste to disguise it with flavorings.
That said, I do have a particular fondness for non-tea-leaf type teas like roasted barley tea, soba tea, chrysanthemum tea, rose tea, etc. Especially in the evenings when I want to sip something and relax.
It's not about disguising it...it's about complementing it.
In this case, it's not orange flavoring in the tea...it's just some small pieces of orange rind.
You may as well have the same complaints about chai tea.
