六大茶类
liù dà chá lèiChinese tea is a single leaf — Camellia sinensis — transformed six different ways by oxidation and processing. This path walks the full spectrum, from fresh-green to aged-dark, then turns to ceremony and craft.
The Six Classes
China's tea taxonomy is built on one variable: how much oxygen the leaf is allowed to touch before heat stops the process. At one pole sits green tea (no oxidation); at the other, fully-oxidised black tea. In between come white, yellow, oolong, and dark teas. Post-fermented dark teas — including 普洱 Pǔ'ěr — form a class of their own, aged rather than simply dried.
Herbal tisanes (花草茶 huācǎo chá) fall outside the six-class system entirely: they use no tea leaf, so they carry no caffeine and no place on the oxidation ladder.
The character 茶.html">茶 itself arrived late in the written record. Before the Tang dynasty standardised the single graph and the single reading, tea was written 荼 (tú) — the same character used for a bitter herb. The Tang poet Lu Yu's Chajing (茶经, Classic of Tea) fixed both the character and the culture around 760 CE, and the Tang court's adoption of tea as a taxable commodity of state turned a regional drink into a civilisational institution. Tea moved from medicine to elite beverage to ceremony to export commodity in roughly that order, each phase leaving vocabulary and practice the next phase built on.
Reading Path
茶 · The Character — The glyph itself: grass radical over 木+人, a phono-semantic compound that arrived late in the written record. The compounds it generates radiate outward into everything tea touches.
茶 · Overview — How a single plant became the world's most-consumed beverage, the role of the Tang dynasty in standardising the culture, and the vocabulary of tasting.
绿茶 · Green — The oldest processed form; steamed in Japan, pan-fired in China. Longjing and Biluochun sit at the top of the canon.
白茶 · White — The bud and young leaves are simply withered and dried. Silvery, subtle, and fast-rising in international markets.
黄茶 · Yellow — A brief smothering step (渥黄 wò huáng) after firing mutes the grassiness of green without full oxidation. The most obscure of the six.
乌龙 · Oolong — Partially oxidised (15–85%), shaped into balls or twisted strips. Floral Tieguanyin to roasted rock oolongs — the broadest flavour range of any class.
红茶 · Black — What the West calls 'black tea,' Chinese calls red — for the colour of the liquor, not the leaf. Keemun and Dianhong are the benchmarks.
花草茶 · Tisanes — Chrysanthemum, osmanthus, rose, and dozens of medicinal herbs steeped without a leaf of Camellia sinensis. Outside the six-class system entirely.
工夫茶 · Ceremony — Small pot, tiny cups, multiple short steeps — a discipline that turns preparation into attention.
茶具 · Utensils — Gaiwans, Yixing clay pots, fairness cups, and bamboo tongs: the tools that shape the experience as much as the leaf does.
茶文化 · Culture — Tea and politics, tea and poetry, tea and social hierarchy: how the leaf became a thread woven through all of Chinese civilisation.
茶道 · The Way — The aesthetic philosophy behind the cup: the Daoist undertone that runs through all serious tea practice.

Companion hubs on this site: The 哲学 — Philosophy hub provides the Daoist undercurrent in tea culture: the concept of 道 in 茶道 is the same 道 that Laozi put at the centre of his cosmology. The 中医 — Medicine hub explains why many teas are classified by temperature and flavour properties: the classification system is identical to the one used for medicinal herbs.
Primary texts: Lu Yu's Chajing (茶经, Classic of Tea, c. 760 CE) is the founding text of Chinese tea culture — available in Francis Ross Carpenter's English translation. For contemporary context, James Norwood Pratt's New Tea Lover's Treasury remains a useful bridge between the Chinese taxonomy and Western consumption habits.
