Thesis

Read through modern tea science, “剑南以彭州上绵州蜀州次邛州次雅州泸州下” is not a lab result but a set of variables: cultivar, soil, light and plucking standard.

Text

“In Jiannan Circuit, Pengzhou is best, Mianzhou and Shuzhou next, Qiongzhou next, and Yazhou and Luzhou lower.”

Context

剑南道：今四川一带。彭州（今彭州）为上，绵州、蜀州、邛州次之，雅州（今雅安）、泸州较下。

Evidence

• Collation: 各本一致。雅州即今雅安，唐代虽列"下"，后世却以蒙顶茶闻名——可见产区评定的时代局限。
• Existing readings: 吴觉农指出剑南即今四川，是唐代重要的茶区；陆羽列雅州为下，但雅安蒙顶茶后来居上、名冠巴蜀——这也说明茶区兴衰随工艺与时运而变。

Analysis

Modern tea science would split “剑南以彭州上绵州蜀州次邛州次雅州泸州下” into cultivar, soil, light and plucking variables. 吴觉农指出剑南即今四川，是唐代重要的茶区；陆羽列雅州为下，但雅安蒙顶茶后来居上、名冠巴蜀——这也说明茶区兴衰随工艺与时运而变。 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 VIII · The Producing Regions, section 5; the original is in the public domain.

Storage adds another variable: moisture and temperature. 各本一致。雅州即今雅安，唐代虽列"下"，后世却以蒙顶茶闻名——可见产区评定的时代局限。 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 “剑南以彭州上绵州蜀州次邛州次雅州泸州下” as a conclusion. Reading the annotation to section 5 again, it is clearly a judgment with conditions attached.

Textually, 各本一致。雅州即今雅安，唐代虽列"下"，后世却以蒙顶茶闻名——可见产区评定的时代局限。. The point is that “the original” is not a single stable text; name the edition before making a strong claim.
