This is some find! It is indeed incomparable to other puerh like teas, at least the ones I know (maybe very remotely like a fermented version of a Honey Oolong). At first it strongly reminded me of a long-forgotten homeopathic medicine that my mother used to feed her children at the merest hint of a cough, but then the taste turned into a really delicious (slightly) bitter honey. And it just kept going. Only in the last infusions it started tasting somewhat more like an actual puerh tea. The long lasting sweet aftertaste was amazingly good, too.
