The tea plant, cultivar and fresh-leaf chemistry are not three separate lists of terms. They are the starting point for asking what a tea can become. The current articles cover tea-plant form, major cultivars and fresh-leaf compounds, from leaves and plant habit to polyphenols, amino acids and caffeine[1][2].
Flavour potential is not set by a single cultivar or a single compound. Genetics, season, growing conditions and plucking standard all shape the leaf before processing and brewing turn it into a sensory experience. This chapter therefore focuses on factors acting together, not one-to-one explanations for flavour[1][2].
In this chapter
The Botany of the Tea Plant
Every tea — green, white, yellow, oolong, black, dark — comes from one plant — the evergreen woody Camellia sinensis of the Theaceae family. Meet the plant itself: its form, flowers, and the two varieties that decide everything.
The Flavour Chemistry of the Fresh Leaf
A single leaf holds two opposite kinds of substance — polyphenols that make tea astringent and bitter, and theanine that makes it fresh and sweet. Know these molecules, and how shading quietly rewrites their balance, and you hold the key to tea's taste.
Tea Cultivars and an Atlas of Famous Varieties
Behind famous names like Fuding Dabaicha, Longjing 43, Tieguanyin, Shui Xian, Baiye 1, Huangjinya, and Zijuan lie distinct tea cultivars. How are they classified, what teas do they suit, and how were they developed?

Editorial note
Later work will examine seasonal physiology, shading and stress responses, cultivar choice and growing adaptation, and how compositional change can be observed carefully in sensory work. It will also distinguish botanical cultivar names, commercial names and processed-tea names rather than treating market language as botanical classification.
