Yunwu Lücha

Classification and Origin

Category: high-mountain green tea; in commercial logic — a grade/form rather than a distinct cultivar.

Lushan Yunwu (庐山云雾茶, Lúshān yúnwù chá).

Nanyue Yunwu (南岳云雾, Nányuè yúnwù) from Mount Hengshan (衡山, Héngshān), Hunan; Yingshan Yunwu (英山云雾, Yīngshān yúnwù), Hubei; Huading Yunwu (华顶云雾, Huádǐng yúnwù) from the Tiantai Mountains (天台山, Tiāntái Shān), Zhejiang.

Mount Lushan (庐山, Lúshān), Jiujiang city district (九江, Jiǔjiāng), Jiangxi Province (江西省, Jiāngxī Shěng).

Type: green tea (绿茶, lǜchá) — without fermentation, with heat fixation of the green leaf.

Facts

Facts: Interesting Facts

• Mount Lushan is inscribed on the UNESCO World Heritage List as a cultural landscape, and its "sea of clouds" is one of the most recognizable landscapes of China.
• The name "yunwu" is a description of the environment, not a single cultivar: it unites teas from different provinces.
• Due to the cold climate, the harvest of high-mountain yunwu often shifts to May, whereas most famous green teas are harvested in early spring.
• The softness of taste in "cloud-and-mist" teas is achieved by the same natural mechanism as in shaded teas: diffused light preserves amino acids and restrains the accumulation of catechins.

In Conclusion:

Yunwu Lücha is not so much a single tea as an entire family of high-mountain green teas whose name honestly names the primary condition for their emergence: clouds and mist on cool mountain slopes. It is precisely the environment, not a rare cultivar, that shapes their recognizable character — tender downy leaf, bright pale infusion, soft sweetish taste, and clean aftertaste without coarseness.

These qualities are most fully embodied by Lushan Yunwu from Mount Lushan, but the principle "in high mountains amidst clouds, good tea is born" applies equally to its counterparts from Hunan, Hubei, and Zhejiang. For those who value a calm, fresh, and well-balanced green tea, yunwu remains a reliable choice — provided one pays careful attention to origin and practices gentle, short-term storage.

History and Culture

Mount Lushan has long been a center of Buddhism and Daoism; tea cultivation here is traditionally associated with monastic communities.

the mountain is linked to the name of the monk Huiyuan (慧远, Huìyuǎn), founder of Donglinsi Monastery (东林寺, Dōnglínsì); the monastery gardens are considered among the first tea plantations on the slopes.

the poet Bai Juyi (白居易, Bái Jūyì), exiled to Jiangzhou, lived on Lushan; his writings mention the local tea and the hermitage he built there.

Name Breakdown: the name "yunwu" became attached to the Lushan tea during the later dynasties, when high-mountain origin became the primary distinguishing feature.

Botany and Raw Material

predominantly local population plantings (群体种, qúntǐzhǒng), as well as regionalized cultivars for green tea.

bud with one leaf (一芽一叶, yī yá yī yè) for higher grades, bud with two leaves (一芽二叶, yī yá èr yè) for standard grades.

young flushes are abundantly covered with silvery down (毫, háo), visible in the finished tea.

Cultivar: tea bush (Camellia sinensis var. sinensis) — small-leaf variety.

Terroir

Altitude: the main Lushan gardens lie at approximately 500–1200 m above sea level.

Soil: acidic, well-drained mountain soils, rich in organic matter.

frequent clouds and mist, high humidity, significant diurnal temperature variation.

predominance of diffused illumination due to the cloud cover.

Production

heating of the leaf to halt oxidation; most often pan-firing in a wok.

tossing the mass for even cooling.

shaping the cells and initial form of the leaf.

giving the tea leaves their characteristic tight form.

a technique that brings out the silvery pubescence.

bringing the tea to stable moisture content.

Organoleptic Profile

tightly rolled tea leaves of dark green color with silvery pubescence.

fresh, with floral and light nutty-chestnut notes, a characteristic "cool" high-mountain purity.

transparent, light yellow-green, bright.

soft, full-bodied, with pronounced sweetness and a clean, long aftertaste (回甘, huígān).

tender, even, of vivid green color.

Chemical Composition

Amino Acids: elevated values, in the range of 3–5 %, with a high proportion of theanine (茶氨酸, chá'ānsuān).

approximately 18–25 %.

roughly 2.5–4 %.

including epigallocatechin gallate (EGCG) as the principal one.

vitamins, minerals, aromatic compounds.

Health Notes

catechins, primarily EGCG, participate in binding free radicals.

the combination of caffeine and theanine yields a tonic effect without harshness.

low extractability makes the beverage suitable for regular drinking.

Brewing

approximately 3 g of leaf per 150 ml, i.e., about 1:50.

for downy, tender tea, the "top-drop" method (上投法, shàngtóufǎ) is convenient — water first, then leaf — or the "middle" method (中投法, zhōngtóufǎ).

the first infusion is short; subsequent infusions are gradually lengthened; the tea sustains 2–3 full steepings.

Teaware: glass tumbler (玻璃杯, bōli bēi) — to observe the leaf unfurl, or a gaiwan (盖碗, gàiwǎn).

Water Temperature: around 80–85 °C; boiling water coarsens the taste and intensifies bitterness.

Storage

Container: airtight, light-proof packaging or caddy.

Shelf Life: green tea is drunk young; optimally within 12–18 months after harvest.

cool, dry, free of foreign odors and direct light.

for long-term storage, it is permissible to keep at 0–5 °C, always in a tightly closed package.

Price and Authenticity

depends greatly on grade and origin; genuine high-mountain leaf is noticeably more expensive than lowland green tea.

lowland green tea passed off as high-mountain, or tea from outside the protected area marketed under the "Lushan" label.

announcements of "pre-Qingming" Lushan yunwu should raise suspicion, as the genuine harvest here is late.
