Thesis

Section 6 is not really about “末之上者其屑如细米末之下者其屑如菱角”; it is about how Lu Yu turns tea from a local product into an object of argument.

Text

“The finest powder is fine as rice-grains; the inferior is coarse as water-chestnuts.”

Context

末：碾成的茶末。屑如细米：细如米粒。屑如菱角：粗如菱角。

Evidence

• Collation: 各本一致。吴觉农注：唐代用碾碾茶，末之粗细直接关系茶汤溶出。
• Existing readings: 吴觉农指出茶末粗细决定出味速度：细末快出易苦，粗末慢出味淡——陆羽"细米为上"的标准，与今人"碎茶不耐泡"的经验完全一致。

Analysis

Formally, the section gives a judgment, adds material detail, then returns to human practice. 末：碾成的茶末。屑如细米：细如米粒。屑如菱角：粗如菱角。 That is why the Classic of Tea reads as an argued book rather than a miscellany.

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 V · The Brewing, section 6; the original is in the public domain.

Modern tea science would split the sentence into cultivar, soil, light and plucking variables. 吴觉农指出茶末粗细决定出味速度：细末快出易苦，粗末慢出味淡——陆羽"细米为上"的标准，与今人"碎茶不耐泡"的经验完全一致。 The variables remain useful, but none of them alone explains the cup.

Storage adds another variable: moisture and temperature. 各本一致。吴觉农注：唐代用碾碾茶，末之粗细直接关系茶汤溶出。 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 “末之上者其屑如细米末之下者其屑如菱角” as a conclusion. Reading the annotation to section 6 again, it is clearly a judgment with conditions attached.
