I gave it two chances to this tea, and I am happy to have done so!
First time I brewed it gong fu style with a gaiwan of 130ml, but I don’t know, probably because I’m still not an expert of this style of brewing, but it seemed to me to flat and “simple”. Beautiful green color, strong taste of chesnut since the first infusion, but a weird “thermal” flavor was always persistent. Not bad but I was not so enthusiastic. Very nice green leaves with white dots at the edges once they are open.
Second time I tried brewing it in a tall glass, and well, it changed. Still this good taste of chesnut was persistent, but the tea revelead his more fresh taste leaving a pleasant sensation in the mouth. It has never been astringent.
