If I blindly tasted this shou I would have thought it was a 30yr sheng. It seems to be accepted that shou is a shortcut for producing something that tastes sorta like a well aged sheng but rather misses the mark yet if it’s good shou is its own thing. When I first tasted a sample of this I was instantly reminded of a 1985 tuo of gushu sheng made of Nanuo and Banzhang material I was lucky enough to procure . The elegantly woody, tobaccoish autumn forest notes were all there. The only thing it lacked was the sink into your chair and grin at the floor for the next 4 hours qi of the tuo. The qi I got from this was the calm but energetic qi I expect from a Jingmai. Bottom line…to my palate this stuff tastes not like a shou but a well aged sheng. If these folks could figure how replicate the qi of a 30yr sheng they could retire quite comfortably… as for now, they got the taste nailed.
