The White Tea That Isn't White Tea

Every spring, Anji County in northern Zhejiang harvests a tea whose name, in Chinese and in English, is white tea. Anji Baicha. 安吉白茶. The industry around it is worth more than seven billion yuan a year, about a billion US dollars. It is a green tea.

This is not a mistranslation and it is not a fraud. It is two meanings sharing one word. The white in Anji Baicha describes the color of the leaf on the bush. The white in the tea this Trust keeps describes what is done to the leaf after picking, which is almost nothing. One name points at a plant. The other points at a process. Only one of them is entered here.

A leaf that loses its color in the cold

The cultivar is Bai Ye No. 1, 白叶一号, a temperature-sensitive albino mutant of Camellia sinensis. In cold spring air its new shoots come up pale, yellow-white to nearly white, because chlorophyll biosynthesis is inhibited at low temperature. As the air warms, the mechanism recovers and the leaf greens back up, within about a month.

The thresholds have been measured. Li and colleagues, working through the albescent stages of Anji Baicha and publishing in PLoS One in 2015², tracked the shoot through four states: yellow-green near 14 degrees Celsius (57 Fahrenheit), early white near 18.5 Celsius (65 Fahrenheit), late white near 17 Celsius (63 Fahrenheit), and re-greening once the air climbed past 22 Celsius (72 Fahrenheit). So the pale window is narrow and it is weather. A warm week closes it. A cold one holds it open.

The same study found something in the leaf while it is pale. Amino acid content rises significantly against normal green shoots: glycine, serine, tryptophan, citrulline, glutamine, proline, valine. That is why the finished tea reads brisk and savory in a way most green teas do not. The chemistry belongs to the cultivar and the cold, not to the maker. Nobody withered it into being. The bush did it, and then stopped doing it in May.

The step that is not taken

The Hangzhou Municipal Forestry Bureau published a page in 2022 titled, in translation, Anji Baicha, why is it not white tea?³ It sets out the process without ornament: the fresh leaf is spread to lose some water, 摊青, then fixed, 杀青, the kill-green, then shaped, 理条, then dried, 干燥. The bureau classifies the result as green tea, because that is what that sequence produces. Pan kill-green for green tea generally runs 260 to 280 degrees Celsius (500 to 535 Fahrenheit)⁵, hot enough to destroy the leaf's enzymes fast, so oxidation stops before it starts and the stem does not redden or blacken.

Now the tea this site exists to keep. The leaf withers. The leaf dries. There is no fixing step at all. No pan, no steam, no heat brought in to arrest the enzymes. The oxidation is not stopped; it is allowed to go slowly and quietly for as long as the wither lasts, and then the drying ends it. Unrolled, unfired.

One process is built around a step. The other is defined by the absence of that same step. They cannot be the same category, whatever the two teas are called, and the pale leaf on the Anji bush makes no difference to the arithmetic. A white leaf that meets a hot pan on the day it is picked is a green tea. A green leaf left alone for two days on a withering rack is a white tea.

One tree, found in 1982

The cultivar has a single origin, and it is recent.

During a Zhejiang provincial agricultural survey in 1982, workers found one tea tree, then reckoned to be over a hundred years old, growing at roughly 800 meters (2,600 feet) in Anji county. Its shoots ran white in the spring. It set very few viable seeds, so it could not be propagated the ordinary way. Growers cloned it instead, and the clones became the registered cultivar Bai Ye No. 1, planted at scale from the 1990s onward. Every bush in the county traces back to that one tree. Lastea's account of the discovery⁴ also notes scarcer records from 1930 mentioning wild white tea trees in the same area. That thread is thin. The 1982 tree is the one the industry actually descends from.

The figures, entered as found

Xinhua reported on 8 April 2026 that white tea had entered harvest season in Anji¹. The figures in that report are worth keeping in one place.

Output in 2025: 2,630 tonnes (about 2,900 US tons). Annual output value of the county's tea industrial chain: more than 7 billion yuan, about US$1 billion. Tea-related tourist trips in the prior year: more than 5 million.

That is a substantial industry built on one mutant tree and a cold April. In its own country, the name has never confused anyone.

Two axes, one word

Chinese tea names do many jobs. Some name a place. Some name a shape, or a cultivar, or a processing category, and often a name carries two of those at once. Anji Baicha names a county and a leaf trait. Fuding Baicha and Zhenghe Baicha name a county and a method.

So the word bai is doing different work in each. In Anji it is descriptive and literal: growers look at the bush in early April and the shoots are pale, and they have called them white for as long as they have picked them. In Fuding it is a category term for tea made by withering and drying, and it applies whether the leaf is the plump downy bud of Da Bai or the coarser late-season leaf of shou mei. Neither use is wrong. They are simply measured along different axes, one describing the raw material and one describing the work, and they happen to arrive at the same syllable.

Anji Baicha is a good tea. It is prized in China for exactly the quality its chemistry predicts, and none of what is written above is an argument against it. It is an argument against one shelf label.

What it costs a buyer

The practical consequence is small and specific. If you buy white tea and receive Anji Baicha, you will get a green tea: pan-fixed on the day of picking, flat-shaped, savory, best at a lower water temperature, and finished within a season. You will not get a leaf that spent thirty to seventy hours on a rack losing water in the open air. You will not get a tea that repays being kept for years, because it was not made to change.

Nothing was taken from you. The label was simply wrong.

Anji Baicha is a green tea. The Trust records it here once, under green, and leaves it there.
