1990 Zhong Zhuan (Blue Zhong) Sheng Puerh was once a tea cake, but was only available in chunks broken from that, thus also in smaller quantities than 400g. This also makes preparing it a bit easier, as you basically just have to take one of the chunks and put it into the pot (although I enjoy preparing Puerh with the proper equipment).
It is quite a wily tea. It starts considerably bitter, which after some consideration reminded me of an overextracted espresso, only to prepare the palate for the long-staying sweetness that follows. It has similarities to pumpkin and red grapes. Will retry this after some more proper humid storing.
Flavors: Astringent, Bitter, Grapes, Pumpkin, Sweet
