This really is reminiscent of a Wuyi Rock Oolong.
It’s sweet, woodsy, and like dark fruit (think plum without being sour at all, or almost like peach). The texture was thick. Their description of it having a “mineral quality” is spot on… it is very enjoyable.
Personally, this isn’t the one I’d choose out of the lot from RTR to have around (since I don’t usually have but 1-2 loose black teas around at one time anyway), however, it is really good. Perhaps the most complex and longest lasting of all the ones I’ve tried (even the 3rd steeping was pretty flavorful).
