Reading Notes

P.337, para.2. “yellow alkane alcohols” in this article refer to flavonoids.

P.337, para.3. “dry vet”, “wet vet” are vague translations and descriptions of the tea process. Be aware, and not take these words too lierally.

P.337, para.4. “on customary application” points out the classification respects the existing naming that has arisen from the tea farmers and producers.
