I received this tea as a sample. I’ve been experimenting with sheng recently so I thought I would try a session. The tea leaf is pretty beat up lots of bits and pieces which reminds me of the tibetan flame from the dame year that I have on hand, but this one is better.dry leaf smelled like smoke, similar or a lapsang but not quite as much pine tar. The Guoyan is very good, not great. The tea elicits a foggy feeling, and some tea drunkeness. the infusion fills my mouth with a brothy consistency indicating umami. I have not detected any bitterness in my 205 degree 30 second infusions. This is one of those teas that really grows on me, the first infusion was unremarkable in any way, but as I have been tasting through now the 5th infusion there is getting to be more to like. 6th infusion a sweet coating is taking hold in the back of my mouth, and now there is a cooling effect in my mouth. This is being brewed in a 175 ml yixing with about 10 grams of tea. Indeed, I like this tea a lot. And honestly it is a shame it is now gone.
