Thesis

“甑或木或瓦匪腰而泥篮以箅之篾以系之始其蒸也入” only becomes legible inside Tang tribute tea, monastery tea and literati life.

Text

“The zeng steamer is made of wood or earthenware, narrowed at the waist and sealed with clay. A bamboo tray serves as the grate, tied with bamboo strips. When steaming begins, the leaves enter the grate; when done, they are taken out.”

Context

甑（zèng）：蒸器，古蒸茶用。匪腰而泥：腰部收束并用泥封。箅（bì）：蒸屉。

Evidence

• Collation: “匪腰而泥"之"匪”，有学者校读为"非"（即"腰部收束"），百川学海本作"匪"，属通假用字；四库本同。
• Existing readings: 吴觉农指出：甑为唐代蒸青核心工具，今日本蒸青玉露所用甑器仍存古制；"匪腰而泥"的收腰泥封设计，是为了让蒸汽在甑内回流不散，是古代"以器定味"的巧思。

Analysis

The largest gap between Tang and now is that tea was simultaneously medicine, tribute and everyday practice. 吴觉农指出：甑为唐代蒸青核心工具，今日本蒸青玉露所用甑器仍存古制；"匪腰而泥"的收腰泥封设计，是为了让蒸汽在甑内回流不散，是古代"以器定味"的巧思。 Without that, the chapter collapses into botany.

Conclusion

The section does not give a universal rule. It demonstrates a method: read the text, the annotation and the Tang context together before making a modern claim.

Water and fire magnify the difference. The same leaf at a higher temperature or a longer steep changes the sweet-bitter balance; the text only becomes operational at the brewing stage.

Modern tea science would split the sentence into cultivar, soil, light and plucking variables. 吴觉农指出：甑为唐代蒸青核心工具，今日本蒸青玉露所用甑器仍存古制；"匪腰而泥"的收腰泥封设计，是为了让蒸汽在甑内回流不散，是古代"以器定味"的巧思。 The variables remain useful, but none of them alone explains the cup.

Storage adds another variable: moisture and temperature. “匪腰而泥"之"匪”，有学者校读为"非"（即"腰部收束"），百川学海本作"匪"，属通假用字；四库本同。 Old and young tea do not share one shelf life, so “the older the better” is not a rule.
