Lao Ban Zhang may be know to be the King of Pu-erhs.  Originally harvested from the Ban Zhang mountain. 
 
Pu-erh is a variety of fermented tea produced in Yunnanprovince, China.
Also, it was named after the trading post for dark tea during imperial periods of China.
 
Ripe, compressed cakes, bricks and tuos can be aged for decades or longer. The longer it's aged, the more more depth and texture the taste becomes.
It's fermented for 40-50 days, under-going a mellowing process that changes the tea into something dark red-brown in color.
 
Pu-erh tea is the only type of tea that can be stored for over decades with it being more enjoyable. Enjoy it today or over a very long time.
 
Taste: unique, woody, earthy with light smokey flavour.
