Thesis

Read through modern tea science, “蒸之捣之拍之焙之穿之封之茶之干矣” is not a lab result but a set of variables: cultivar, soil, light and plucking standard.

Text

“Steam it, pound it, press it, roast it, string it, seal it — and the tea is done.”

Context

蒸青制茶六道工序：蒸、捣、拍、焙、穿、封。这是唐代饼茶的完整流程。

Evidence

• Collation: 此句为全书制茶工艺的总纲，各本一致。六道工序名目在历代注本中屡有申说，文字稳定。
• Existing readings: 吴觉农指出"六之"即唐代饼茶全流程：蒸青→捣烂→入模拍压成饼→焙干→穿串→封藏；其中"蒸"法奠定中国绿茶蒸青传统，后传入日本演为玉露制法。

Analysis

Modern tea science would split “蒸之捣之拍之焙之穿之封之茶之干矣” into cultivar, soil, light and plucking variables. 吴觉农指出"六之"即唐代饼茶全流程：蒸青→捣烂→入模拍压成饼→焙干→穿串→封藏；其中"蒸"法奠定中国绿茶蒸青传统，后传入日本演为玉露制法。 They remain testable, but only with their conditions attached.

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.

Source: The Classic of Tea, Chapter III · The Making, section 4; the original is in the public domain.

In Tang context, 吴觉农指出"六之"即唐代饼茶全流程：蒸青→捣烂→入模拍压成饼→焙干→穿串→封藏；其中"蒸"法奠定中国绿茶蒸青传统，后传入日本演为玉露制法。. Tea was tribute, medicine and monastery drink at once, not a standalone commodity; the conclusion cannot be transferred without that context.

Storage adds another variable: moisture and temperature. 此句为全书制茶工艺的总纲，各本一致。六道工序名目在历代注本中屡有申说，文字稳定。 Old and young tea do not share one shelf life, so “the older the better” is not a rule.

As a new reader, I first took “蒸之捣之拍之焙之穿之封之茶之干矣” as a conclusion. Reading the annotation to section 4 again, it is clearly a judgment with conditions attached.
