Puerh (Raw / Sheng)
Vietnam
Vietnamese sheng-adjacent teas made from ancient-tree material in northern Vietnam's highlands, processed in a style similar to raw puerh and sometimes aged. The trees are Yunnan-related assamica cultivars, but the terroir is genuinely distinct from Yunnan: higher humidity, different soil mineral profile, and different tree genetics produce a sheng-shaped tea with its own wild and often more pungent or forest-floor character. These are not puerh by Chinese geographic standard, but for drinkers tracking the sheng style across origins they are the most direct comparison outside Yunnan.
Vietnamese sheng is made puerh-style from old highland trees, wilder and more forest-floor than Yunnan, and a fascinating comparison if you know Yunnan sheng. The trees are the same assamica variety as Yunnan's, so tasting the two side by side is as close as tea gets to a controlled experiment, if a loosely controlled one.
