Identity and origin
Fu brick is a compressed dark tea known for controlled fungal growth commonly called golden flowers. The visible growth is process-specific and should not be generalized to other molds.
Craft and leaf style
Prepared dark-tea material is steamed, compressed and conditioned so the desired microbial transformation can develop before final drying.
Aroma, taste and texture
Sweet grain, mushroom, wood, dried fruit and a mellow, soft body can appear.
Practical guidance
Break cleanly, use boiling water and brew in a pot or simmer gently; keep unused brick dry and odor-free.
Identification and caution
Golden flowers require correct identification and production context. Do not assume any yellow or fuzzy growth is desirable.
