Bai Ye Yi Hao

The albino-mutant cultivar behind Anji Bai Cha. Its shoots emerge nearly white in early spring because low temperatures suppress chlorophyll, and green again as the season warms — which is why the harvest window is measured in days rather than weeks.

Where it sits in the botany

Bai Ye Yi Hao is recorded under Camellia sinensis var. sinensis, the variety group one level above cultivar. It is associated with China, which is where it was selected or is most widely planted rather than the only place it grows.

Registration code: Bai Ye 1. A breeding or registration code identifies the selection in an institutional register and is often the name a grower uses when the trade name is not.

Also transliterated as: bai ye yi hao.

What the plant is like

The pale leaf carries unusually high amino-acid content relative to catechins, which is the direct cause of the tea’s sweetness and near-total lack of bitterness. It is a green tea despite the name.

Why a grower plants it

Yield, hardiness, when it buds, what it resists and whether a machine can cut it. This is the half of a cultivar’s identity that decides what is actually in the ground, and it is usually left out of writing aimed at drinkers.

An agronomically awkward plant kept for a chemical accident. The pale shoots appear only while temperatures stay low and green again as the season warms, so the harvest window is measured in days rather than weeks and a warm spring shortens it further — which puts the entire year's premium crop into a very short labour peak. The plant is not otherwise vigorous, and the pale tissue that gives the tea its character is chlorophyll-deficient tissue, so the bush is doing less photosynthesis during exactly the period it is being picked.

What it does in the cup

Reported as strikingly sweet with very little bitterness and a light, clean body — closer in balance to a shaded Japanese tea than to a conventional Chinese green, despite ordinary pan-firing.

How much of this is really the cultivar?

This is the strongest cultivar-attribution case in the green-tea part of the catalogue, and it is strong because the mechanism is compositional rather than aromatic: the pale shoot carries an unusually high amino-acid level relative to its catechin level, and that ratio is what a drinker registers as sweetness with almost no bitterness behind it. The tea is a green tea despite the name — bai refers to the colour of the growing leaf, and the processing is ordinary pan-firing. Buying it as a white tea is the commonest error attached to it.

Cultivar, growing site and processing all shape a cup, and the cultivar is very often the smallest of the three. It is also the one that fits on a label, so almost every commercial incentive runs toward overstating it. This section is on every cultivar page that has been reviewed for it, including the ones where the honest answer is “less than you would think”.

What it is usually made into

The categories this cultivar is typically processed into. It is a statement about common practice, not a limit — processing decides the category, and a cultivar can be taken down more than one route.

Green tea — Tea whose oxidation is halted early by heat, keeping the leaf green and the cup fresh, vegetal or marine in character.

Guides covering this cultivar

Albino, yellow and purple: the tea plants with a pigment fault — A handful of tea cultivars produce leaves that are not green — white, yellow, or purple. In every case the colour is a property of the plant rather than of the processing, and in every case the name of the resulting tea has been confused with a processing category.

Bai Ye Yi Hao vs Huang Jin Ya — Two pigment-mutant cultivars that make very sweet, very low-bitterness green tea and are both mis-sold on the strength of their colour. One greens as the season warms; the other stays golden, and neither is a white or yellow tea.
