Sheng vs Shu
Definition
The two fundamental types of pu-erh tea. Sheng (raw) pu-erh is traditionally processed and aged naturally over years or decades, gradually developing complexity. Shu (ripe) pu-erh undergoes accelerated fermentation (wo dui) over 45–60 days to simulate aged sheng's dark, smooth character - a technique invented in the 1970s.
Why it matters
Confusing sheng and shu is one of the most common beginner mistakes in pu-erh. They taste, age, and cost completely differently. Young sheng is bright and astringent; shu is dark and earthy from day one. Knowing the distinction helps you buy with intention and understand why aged sheng commands exponentially higher prices.
