I enjoyed a smokiness in first couple of steeps.
Started to notice some oak, ash, maybe tobacco, and yes some bitterness.
Giving some time between steeps helped notice some apricot aftertaste, but not as forward as in other raw pu’ers. Some butter also in aftertaste, but subtle. I had tried this tea a few years ago as a sample, and I still have a bit left, so am trying again. Am being cautious not to drink too much because some reviews note its potent chi, and I recollect that as well from a few years ago. For me, it is an interesting tea to try, especially as I imagine the high altitude and pristine environment from where it came.
