What Exactly Lies Behind the Name “Moonlight White Tea” – 月光白 Yueguang Bai?

08. 12. 2025

Moonlight White Tea — 月光白 Yueguang Bai — is one of the most poetic teas Yunnan has to offer. Its aroma is cool and pure, quiet like moonlight falling on leaves at night. It does not fill the room with intensity like Dancong 单丛; instead, it gently dissolves into the space, subtle and elusive.

The taste is sweet and long-lasting, natural, smooth, with a slowly unfolding sweetness that stays on the tongue long after you finish drinking.

Origin and the special black-and-white beauty of the leaves

月光白 Yuèguāng Bái belongs among the special types of tea from the Puer area and comes from 景谷 Jǐnggǔ county in Yunnan. Its production is tied to an unusual appearance: the upper side of the leaf is dark, while the underside shines with white downy hairs. The whole bud thus resembles a thin crescent moon – hence the name “moonlight white”.

There are two reasons for this name:

Appearance of the dry tea
The leaves are black and white, with distinct white hairs, and their shape resembles a crescent moon – “the moon at night”.
Processing without sunlight
It is harvested and processed exclusively at night or in rooms shielded from the sun. The tea is dried slowly in moonlight or in shade.
This “night journey of the tea” reflects the Taoist concept of „阴柔 Yinrou“ – gentleness and softness.

For this reason, 月光白 Yueguang Bai is sometimes poetically called “Moon Beauty — 月光美人 Yueguang Meiren”, because the tea was traditionally picked by young women.

The secret of production: a tea made under the moon

According to tradition, the harvest begins only after midnight and ends before dawn. Only large buds and leaves from Yunnan tea trees 大叶种 Dayezhong are picked.

In a dark room, the leaves are spread out on bamboo mats 竹席 zhuxi, where they are left to wither freely, without piling and without exposure to sunlight. Each batch must be processed within a single day. The exact procedures are often kept secret, which adds an aura of mystery to the tea.

Is Yueguang Bai a white tea? And why, in fact, not?

Many people think that 月光白 Yuèguāng Bái is a type of white tea. The truth is more complicated.

Its processing is similar to that of white tea from Fujian – 白茶 Baicha – but the Yunnan “moon” has its own signature.
During withering, light controlled oxidation – 轻发酵 qing fajiao is carried out.

Thanks to this:

bitterness and astringency are reduced,
the taste is gentle, sweet and round,
the liquor is clear and smooth,
the tea withstands many infusions,
it contains more dissolved solids than ordinary white teas from small-leaf cultivars.

Appearance, aroma and taste: a tea like moonlight

In the cup, 月光白 Yuèguāng Bái feels like tea poetry:

leaves – black and white, as if moonlight were resting on them,
liquor – bright yellow, clear, becoming even more limpid with each infusion,
aroma – floral, lightly honeyed, ethereal and elegant,
taste – sweet, soft and smooth, combining the freshness of white tea with the gentle depth of puer.

After swallowing, a long, sweet returning aftertaste 回甘 huigan appears.

Tea as a princess: the sacred beauty of 月光白

Among the many teas cultivated by the Bulang people, it was precisely 月光白 Yuèguāng Bái that was chosen as the purest and most noble gift, intended to honour royal lineages.

In folk stories, it is said that this tea is as holy, pure and noble as the Seventh Princess herself. It is understood as her tea embodiment, like the moonlight falling on the mountains where she lived her new life.

That is why 月光白 is often described as a tea with the beauty of a princess — delicate, radiant and rare.

The legend of the Seventh Princess and the birth of the tea 月光白 Yueguang Bai

Among the people of the 布朗族 Bùlǎngzú — the Bulang ethnic group — a beautiful legend is still told today, linked precisely to the tea 月光白 Yuèguāng Bái.

Long ago, the Seventh Princess 南发来 Nánfālái, daughter of the king of 景洪 Jǐnghóng, was sent to the ruler of the principality of 孟勐 Mèngměng. She was renowned for her beauty, kindness and courage — the personification of wisdom and elegance of the Tai people living on the fertile river plains.

So that lasting peace and friendship might reign between the Bulang and the Tai, the princess gave up the splendour of palace life and went high into the mountains. There she married the Bulang chieftain 叭岩冷 Bāyánlěng, with whom she opened a new chapter in the history of her people.

Princess 南发来 Nánfālái did not become only a symbolic wife.
She brought with her knowledge that changed the face of Bulang society:

she taught the local people how to build terraced rice fields,
she passed on skills for large-scale tea cultivation,
and she helped them leave behind primitive ways of life and step towards civilisation.

The first true tea culture 茶文化 chá wénhuà in this region was thus born precisely among the Bulang — and its source was the Seventh Princess. That is why, in Bulang tradition, she is honoured as “Mother of the clan — 族母 zúmǔ” and also as “Mother of tea — 茶母 chámǔ”.

(Another branch of the Bulang people later settled in Cambodia and became part of the nation that created the famous culture of Angkor 吴哥 Wúgē, one of the wonders of world civilisation.)

How to properly prepare 月光白 Yueguang Bai

Moonlight tea is delicate – especially because it contains many buds. Therefore:

Do not use water that is too hot!

Water at 80–85 °C is ideal. Boiling water would “burn” the fine buds.

Cold brew is also wonderful – 冷泡 lengpao

If you don’t have the possibility to boil water:

Take a small handful of tea.
Put it into a bottle with clean or mineral water.
Close and shake.
In a few minutes you have a cooling, sweet infusion.

Cold-brewed 月光白 is even sweeter and smoother.

Character of the tea: the coolness of the moon, the warmth of experience

Fresh 月光白 is usually “cool” in nature — 茶性偏寒 chaxing pian han.
But tea that has aged for several years gradually rounds out and becomes warmer and gentler.

Four-year-old 月光白 is already soft, pleasant and suitable for all age groups.

月光白 Yueguang Bai is a tea that unites the poetry of the night, the subtlety of Taoist philosophy and the richness of Yunnan’s large-leaf tea trees.
It is not white, not green and not a classic Puer — it is a moon tea, unique and unmistakable.
