This is your generic aged ripe puer. The smell is of earth, wet rotten wood and mushrooms. Some transitory fishiness, which is surprising given the age of the cake. The taste is typical for the aged shou but it is not complex and the aftertaste does not linger.
Nothing bad to say but nothing good either. The main pros are that it is cheap and comes in convenient 100 g cakes. I will relegate it to my office to sip it absent-mindedly while concentrating on work.
