The passage

“The fu cauldron is made of raw iron. Its inner mold is clay, so the inside is smooth and easy to scour; its outer mold is sand, so the outside is rough and endures the flame.”

Modern tea science

A modern tea-science reading of “The fu cauldron is made of raw iron. Its inner…” separates four layers: ecology, cultivar, processing, and brewing.

Soil drainage, light, temperature, and cultivar shape the amino acids, catechins, and aromatics in the leaf. Those compounds then meet water, heat, and time.

Science can explain why an old observation often works, but it does not make the observation universal. Context still matters.

Reading note

Read the passage once for the image, once for the judgment, and once for the practice it implies.
