Ānjí Bái Chá (安吉白茶) — White-Leaf Green Tea

Ānjí Bái Chá (安吉白茶, "Ānjí White Tea") is a Chinese green tea from Ānjí county in northern Zhèjiāng province. Despite containing "white tea" (白茶 bái chá) in its name, it is processed and classified as a green tea — the "white" refers not to the processing method but to the leaf colour. The tea is made from a rare natural cultivar mutation with very low chlorophyll content: the young spring leaves emerge almost white or pale jade-green, rather than the usual dark green. As the season progresses and temperatures rise, the plants return to normal green.

TL;DR: Green tea (pan-fired) from an albino cultivar in Ānjí, Zhèjiāng. Not white tea — the name refers to the pale leaf colour, not the processing method. Character: milky, sweet, distinctly umami, very low bitterness. Brew at 75–80°C, 3–4 g per 100 ml, 15–25 s. Only available míng qián — the albino leaves turn green after Qīngmíng.

The albino cultivar

The tea comes from a specific cultivar known as Bái Shū (白叶一号, White Leaf No. 1) or Ānjí Bái Chá cultivar — a natural genetic mutation of Camellia sinensis discovered growing wild in Ānjí county in 1982. The mutation produces a temperature-sensitive reduction in chlorophyll synthesis: at the low temperatures of early spring (below ~23°C), the leaves produce far less chlorophyll than normal, resulting in a pale, almost white colour. Once temperatures rise above this threshold, normal chlorophyll production resumes and the leaves turn standard green.

This metabolic peculiarity has a direct effect on the tea's chemistry:

• Very low chlorophyll → pale colour, light vegetal flavour
• Compensatorily high theanine (amino acid) → intense sweetness and umami
• Lower catechins relative to theanine → almost no bitterness

The result is a tea with one of the highest theanine concentrations of any Chinese green, rivalling gyokuro in amino acid content.

Harvest window

The albino condition only occurs in early spring — a window of roughly three to four weeks before Qīngmíng (~April 5). After temperatures rise, the leaves turn green and lose the unique chemical profile. This makes all genuine Ānjí Bái Chá míng qián by definition — the only harvests of the characteristic pale leaf occur before Qīngmíng. Teas labelled "Ānjí Bái Chá" harvested after Qīngmíng are from green leaves and are essentially standard Zhèjiāng green teas of different character.

Taste profile

• Appearance: Pale jade to ivory-green leaves, flat or lightly curved, with a distinctly lighter colour than any other Chinese green
• Fragrance: Clean, slightly grassy-sweet, with faint dairy/cream notes
• Taste: Milky sweetness, pronounced umami (the highest theanine concentration creates a savoury-sweet quality similar to high-grade Japanese gyokuro), very minimal bitterness
• Body: Light to medium — not thin, but not heavy
• Finish: Clean, sweet, lingering

Processing

Ānjí Bái Chá is processed as a green tea: pan-fired kill-green (shā qīng), light rolling, and drying. Some producers make a flat-pressed version (similar to Lóngjǐng); others leave the leaf slightly curved. Both are correct and reflect producer preference rather than quality difference.

Brewing

Glass is ideal — watching the pale leaves unfurl in clear water is part of the aesthetic. The first steep is pale and clean; subsequent steeps gradually intensify.

Is this really a green tea?

Yes. The processing is identical to green tea: kill-green (pan-firing), light rolling, drying. No withering beyond a few hours, no oxidation, no yellowing or fermentation. The name "bái chá" in this context refers to the leaf colour, not the tea category. Genuine white tea (Bái Háo Yín Zhēn, Bái Mǔ Dān) is made from different cultivars with wilting-and-drying processing and entirely different character. → White Tea Overview

FAQ

Why is it called "white tea" if it's a green tea? The "white" (白) refers to the pale colour of the young spring leaves from this albino cultivar — they emerge almost white due to very low chlorophyll production at cool temperatures. The processing is standard green tea (pan-firing). Genuine white tea (Bái Háo Yín Zhēn, Bái Mǔ Dān) is an entirely different product made with different processing. The naming overlap causes persistent confusion.

What makes Ānjí Bái Chá taste umami? Theanine — an amino acid that contributes sweetness and savoury depth. The albino cultivar's reduced chlorophyll means the plant accumulates theanine rather than converting it to catechins (which would add bitterness). The result is one of the highest theanine concentrations in any Chinese tea — a measurably sweet, almost savoury quality that experienced tasters compare to gyokuro.

Can Ānjí Bái Chá be found year-round? No. The albino condition lasts only during early spring cold (below ~23°C) — typically a three-to-four week window before Qīngmíng (April 5). After that, the leaves turn standard green. Genuine Ānjí Bái Chá is a míng qián spring-only tea. Any version outside this window is from green-phase leaf and is a different product.

How does Ānjí Bái Chá compare to Lóngjǐng? Both are pan-fired Zhèjiāng greens, but very different. Lóngjǐng has a toasted-chestnut, vegetal character with more body and structure. Ānjí Bái Chá is milky, sweet, umami-forward with almost no toasted notes. Lóngjǐng's colour is deeper green; Ānjí Bái Chá is pale jade to ivory.
