It is not recommended to drink tea made with moldy chenpi. Mold indicates dampness or spoilage and compromises both flavor and safety.
Common signs of mold
- Patchy mold growth or dark spots on the surface.
- Musty, sour, or damp odors.
- Sticky texture, clumping, or clear signs of moisture damage.
Why it should be discarded
Mold affects flavor and signals uncontrolled spoilage. If mold is found, it should be discarded rather than used.

Storage tips
Store chenpi and chenpi pu'er in a dry, ventilated, light-shielded place, away from moisture and strong odors. Check periodically and address dampness early to prevent mold.
