Cāngshān xuě lǜ · new.thetea.app

Cangshan Xue Lü (苍山雪绿, Cāngshān xuě lǜ) is a Yunnan green tea of twisted form, belonging to the hongqing (烘青, hōngqīng — “fire-dried”) type. Created in 1964 at the famous Xiàguān Tea Factory (下关茶厂, Xiàguān Cháchǎng) in Dali. Raw material is collected on the slopes of the Cāngshān mountain range (苍山, Cāngshān) — the sacred mountain of the Bai people — by the shores of Ěrhǎi Lake (洱海, Ěrhǎi). The production technology was included in China’s national intangible cultural heritage list (2011), and in 2022 — in UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity as part of “Traditional tea processing techniques and associated social practices in China.”

1. Classification and Origin:

Type: Green tea (non-oxidized). Hōngqīng (烘青) — fire-drying; by form — twisted-curved (曲条形, qū tiáo xíng).
Category: Yunnan large-leaf green tea; provincial famous tea of Yúnnán (云南省级名茶).
Origin: China, Yúnnán Province (云南, Yúnnán), Dàlǐ Bái Autonomous Prefecture (大理白族自治州, Dàlǐ Báizú Zìzhìzhōu), Cangshan mountain range and coastal zone of Erhai Lake.
Geographic coordinates: Approximately 25°35′–25°45′ North latitude, 100°05′–100°15′ East longitude.

2. History and Cultural Significance:

History: Dali’s tea culture spans over a thousand years. Tāng poet Jiǎ Dǎo (贾岛, Jiǎ Dǎo) in his poem “Seeing off Zhu Xu returning to Jiannan” wrote about “young shoots of snow tea” (芽新抽雪茗), which allows dating the consumption of Cangshan “snow teas” to at least the Tang era (618–907). Dali is a city with deep connections to tea trade: during the Míng and Qīng periods it was the main transit point on the southwestern section of the Ancient Tea Horse Road (茶马古道, Chámǎ Gǔdào).

Modern Cangshan Xue Lü tea was created in 1964 by specialists at Xiaguan Tea Factory — an enterprise famous primarily for producing Yúnnán tuóchá (沱茶). The factory used raw material from tea gardens on the slopes of Cāngshān and developed ān original technology with triple drying (三次烘焙, sān cì hōngbèi), ensuring multi-layered aroma. In 1980–1983, the tea received the title “Famous Tea of Yunnan Province” for three consecutive years. In 1989 — an award from the Ministry of Agriculture, Animal Husbandry and Fisheries for quality. In 2011, the production technology was included in the national intangible cultural heritage list, and in 2022 — entered the UNESCO list as part of “Traditional tea processing techniques of China.”
Name: “Cangshan” (苍山) — the name of the mountain range dominating over Dali; “Xue” (雪) — “snow” — refers to the snow-capped peaks of Cangshan and to the abundance of white down on the tea leaf, resembling snow; “Lü” (绿) — “green” — the color of the tea itself. Thus, the name can be translated as “green snow from Cangshan mountains” — a poetic image in which white down is associated with snow on the peaks, and greenness — with living slopes at their foot.
Cultural significance: The tea is inseparably linked with the culture of the Bái people (白族, Báizú) and with the tradition of “Three Cups of Tea” (三道茶, sān dào chá) — ritual hospitality of the Bai, where the first cup is bitter roasted tea, the second is sweet tea, the third is “aftertaste of life” tea with spices. Although different varieties are traditionally used for Sandao Cha, Cangshan Xue Lü is one of the most respected representatives of Dali green tea and often serves as the base for the first cup.

3. Botanical Description and Raw Material:

Variety / Cultivar: Main — Yúnnán Shuāngjiāng Měngkù Large Leaf (云南双江勐库大叶种, Yúnnán Shuāngjiāng Měnkù Dàyè Zhǒng) — a national-level large-leaf variety (Camellia sinensis var. assamica), distinguished by powerful, downy buds with high tenderness retention (持嫩性). Polyphenol content > 20%, amino acids ≥ 3.5%, ensuring concentrated and fresh liquor taste. Auxiliary cultivar — Fúdǐng Dàbái Chá (福鼎大白茶, Fúdǐng Dàbái Chá).
Picking: Spring picking begins before the Qīngmíng festival (清明, Qīngmíng, early April) for special grade; before Gǔyǔ (谷雨, Gǔyǔ, mid-April) — for first grade. A total of 12–20 picking cycles are conducted throughout the year. Summer-autumn picking goes to mass varieties.
Picking standard: Special grade (明前特级, míngqián tèjí) — bud with one leaf in initial opening stage; first grade (雨前一级, yǔqián yījí) — bud with two leaves; summer-autumn picking — opened leaves for everyday tea.

4. Terroir and Cultivation Features:

Topography and location: The Cangshan range — a southern spur of the Héngduàn Mountains (横断山脉, Héngduàn Shānmài) — rises above the city of Dali and Erhai Lake. Tea gardens are located on mountain slopes and in the coastal zone. A unique feature is the combination of snow-capped peaks (highest point Madengfeng — 4122 m) with subtropical climate at the foot: in winter snow lies on the peaks, while camellias bloom on the slopes.
Growing altitude: 1500–2000 m; ancient tea trees (古树, gǔshù) are concentrated in the 1500–2000 m belt.
Climate: Average annual temperature 15–16 °C; annual precipitation 1000–1300 mm. In summer and autumn, cloudiness and fog reach 80%, ensuring predominance of diffused light and slowing shoot growth, promoting intensive accumulation of amino acids, caffeine and aromatic oils.
Soils: Slightly acidic yellow-brown soils and sandy loams with pH 4.5–6.0, rich in organic matter and minerals — potassium (K) and selenium (Se).
Core production zone: Southern slope of Cāngshān in Nánjiàn County (南涧县, Nánjiàn Xiàn) and tea gardens at the foot of Tàilǎoshān (太姥山, Tàilǎoshān), supplying about 70% of raw material. Groups of ancient tea trees are concentrated here.

5. Production Technology:

Cangshan Xue Lü is a hongqing (烘青) green tea with twisted leaf form. Key technological principles: high-temperature fixation to “lock in” freshness, light rolling of hot leaf and triple drying to form multi-layered aroma.

Picking (采摘, cǎizhāi): Manual selective picking of young shoots, predominantly before Qingming.
Kill-green (杀青, shāqīng): Processing in rotating drum at 150–200 °C. High temperature quickly deactivates enzymes, preserving green color and fresh notes. Large-leaf Yunnan raw material is characterized by special heat resistance — the tea withstands more aggressive fixation without quality loss.
Rolling (揉捻, róuniǎn): Hot rolling (热揉, rè róu) on the principle “light — strong — light”; with large fleshy Mengku leaf, hot processing ensures twist formation while maintaining integrity. Required shaping degree — ≥ 80% of leaves take the given form.
Shaping (做形, zuòxíng): Straightening and rolling into spiral form (理条搓团, lǐtiáo cuōtuán).
Drying (干燥, gānzào): Three-stage drying (三次烘焙): first — removing grassiness (祛草腥); second — forming chestnut tone (定栗骨); third — locking “cold aroma” (锁冷香) at low temperature. This triple drying is the technological signature of Xue Lü.
Sifting and sorting (筛拣, shāijiǎn): Removing stems, fragments and off-grade fractions.
Final firing (复火, fùhuǒ): Delicate low-temperature finish for aroma stabilization and reducing residual moisture. This stage is especially important for “locking” cold aroma (冷香, lěng xiāng) — a unique characteristic of Xue Lü, manifesting when the cup cools.

Technological feature of Xue Lü: unlike most green teas where finish drying is conducted once, here the principle “three dryings — three rests” (三烘三闷, sān hōng sān mèn) is applied. Between drying cycles, leaves are held in closed containers, allowing moisture to migrate evenly from leaf center to surface, ensuring uniform drying without overheating outer layers. Result — multi-layered aromatic profile where chestnut notes from roasting are complemented by “cold” floral overtones.

6. Organoleptic Characteristics:

Dry leaf appearance: Twisted-curved form (卷曲形); dense, finely twisted leaves of dark green color with oily luster (墨绿油润); tender green shoots show through in places; abundant white down covers the surface like snow coating.
Dry leaf aroma: High, clean and noble (清香高雅), with young corn tones from abundant down (毫香, háo xiāng); a “wild” mountain note is felt — trace of high-altitude ecological terroir (原野香, yuányě xiāng).
Liquor aroma: Develops toward creamy sweetness and deeper chestnut register; cooled cup long retains subtle “cold” aroma — result of triple drying.
Taste: Pronounced freshness (鲜爽, xiān shuǎng) thanks to high amino acid content; dense “body” with oily sensation (醇厚, chúnhòu) from high polyphenol level; quick and intense returning sweetness (huí gān) (回甘) — sweet aftertaste unfolding from tongue root.
Liquor color: Tender yellow, clear and bright (嫩黄透亮) for special grade; yellow-green and clean for first grade.
Spent leaves (wet leaves): Yellow-green color, uniform; shoots elastic and intact.

7. Chemical Composition:

Amino acids: ≥ 3.5% — one of the highest indicators among Yunnan green teas; due to large-leaf Mengku cultivar and high-altitude terroir with slow shoot growth.
Polyphenols (茶多酚): > 20% — ensure taste density and concentration; large-leaf Yunnan tea is characterized by simultaneously high content of both polyphenols and amino acids, giving rare combination of “strength and freshness.”
Caffeine (咖啡碱): Typically 3.5–4.5% for large-leaf raw material.
Vitamins: Vitamin C (up to 200 mg/100 g in fresh raw material), vitamins B₁, B₂, K.
Minerals: Potassium, selenium, manganese, fluorine.
Essential oils: Responsible for multi-layered aroma — pyrazines (chestnut notes from drying), linalool and geraniol (floral-fruity overtones from Mengku cultivar).

8. Health Properties:

Antioxidant protection: High polyphenol content; according to some data, free radical neutralization effectiveness is higher than average green tea, due to concentrated catechin profile of large-leaf raw material.
Mild tonic effect: Caffeine combined with L-theanine gives smooth, sustained alertness without anxiety.
Lipid metabolism support: Catechins and gallated epigallocatechins accelerate fatty acid oxidation.
Antipyretic and cooling action: In traditional Chinese medicine, green tea is classified as “cool” (性凉, xìng liáng) — it’s drunk to relieve heat and refresh in summer months.
Vision support: Catechins and vitamin B₂ help relieve visual fatigue.
Digestive support: Polyphenols stimulate GI tract function and promote microflora normalization.
Cognitive function support: L-theanine supports brain alpha-activity, promoting concentration.

Important: this is general information, not medical advice.

9. Brewing:

Water temperature: 95 °C — notably higher than for most green teas. Large-leaf Yunnan raw material from 2000 m altitude requires high temperature for full flavor and aroma development.
Tea amount: 5 g per gaiwan or teapot of 100–120 ml volume (approximately 1/5 vessel volume).
Vessel: Thin-walled porcelain gaiwan (best option for extraction control and enjoying lid aroma); Yixing teapot from porous clay suits for emphasizing body density.
Process (bottom pouring method — 下投法, xià tóu fǎ, with high flow):
1. Warm gaiwan with boiling water.
2. Add 5 g tea.
3. With high point pour (定点高冲, dìngdiǎn gāo chōng) add 95 °C water.
4. First infusion — 5 seconds, discard (rinse, leaf opening).
5. Infusions 2–4: 10 seconds each — main phase, mountain character development.
6. Infusions 5–6: increase by 5 seconds. Total withstands up to 6 infusions.
Notes: Optimal tasting temperature — around 60 °C: at this temperature amino acid freshness manifests most vividly. Not recommended on empty stomach. People with sensitive stomach can add ginger slice. For insomnia — avoid consumption after noon.

10. Storage:

Airtight packaging; protection from light, moisture and foreign odors.
Optimal: 0–5 °C (refrigerator) in airtight bag or jar. Before opening — hold at room temperature in closed packaging to prevent condensation.
After opening — consume within one month to preserve freshness.
For teas from ancient tree raw material (古树) longer storage under proper conditions is acceptable, however Xue Lü is a freshness tea, and it’s best drunk young. Special and first grades most fully develop in the first three months after production; summer-autumn second grade tea is slightly more stable and can be stored up to six months without noticeable quality loss.

11. Market and Price Range:

Price category: Wide range. Xiàguān Factory (下关茶厂) — original producer — offers special grade mingqian from whole buds for approximately 260 yuan/50 g. Tea from 300-year-old tree raw material from specialized producers (e.g., “Wangfu Yuncha,” 王府云茶) — around 619 yuan/150 g. Rain grade — from 150 yuan/250 g.
Price factors: Tree age (ancient tree raw material significantly more expensive), picking season, grade, producer brand.
How to avoid counterfeits:
- Purchase from authorized dealers of Xiaguan Factory or known Yunnan brands.
- Pay attention to abundant white down — authentic Xue Lü is distinguished by pronounced “snowy” fuzziness.
- Liquor should be clean, bright, without murkiness (except light haziness from down) and without musty smell.
- Large-leaf Yunnan green tea is a niche where counterfeits are rarer than, for example, with Longjing, however substitution of raw material with small-leaf or low-altitude material is possible.
- Verify presence of “green product” certificate (绿色食品) — Xiaguan Factory received this status.

12. Recommended Sources:

Cangshan Xue Lü first appeared in Xiaguan Factory’s product line in 1959 as one of six new products prepared for the PRC’s tenth anniversary, alongside the famous “Cang’er Tuocha” (苍洱沱茶). However, the full commercial version was brought to standard only by 1964.
In the Bai tradition of “Three Cups of Tea” (三道茶, sān dào chá), the first — bitter — cup is prepared from green tea roasted in clay teapot until light crackling: this method traces back to Bai tea culture practices spanning over a thousand years.
The Cangshan mountain range is the collection site of the type specimen of botanical species Camellia taliensis (大理茶, Dàlǐ Chá), described in 1917 — one of the wild relatives of cultivated tea tree. Although Xue Lü is produced from cultivated C. sinensis var. assamica, proximity to wild C. taliensis testifies to the exceptional antiquity of the region’s tea ecosystem.
In 1996, Cangshan Xue Lü and “Gantong” tea (感通茶) were evaluated by the China Food Industry Association as “Outstanding Products of China’s Food Industry.”
Due to using large-leaf Yunnan raw material, Xue Lü allows unusually high brewing temperature for green tea — 95 °C, making it closer in brewing regime to red tea (black tea) and dark teas rather than typical green teas.

13. Authenticity Identification:

Cangshan Green / Yúnnán Green Tea (滇绿, Diān Lǜ): General term for Yunnan green teas from large-leaf raw material. Xue Lü is one of the most prestigious representatives of this group, distinguished by origin from high-altitude Cangshan slopes and original triple drying.
Méngdǐng Gānlù (蒙顶甘露, Méngdǐng Gānlù): Sichuan green tea from small-leaf raw material — significantly more delicate, with floral-bean profile and brewed at 75–80 °C. Xue Lü is denser, more oily, stronger and hotter in extraction regime.
Bìluóchūn (碧螺春, Bìluóchūn): Jiangsu twisted green tea from small-leaf raw material — light, floral, fruity. Xue Lü with similar twisted form differs in fundamentally different taste scale: large-leaf Yunnan leaf gives density unavailable to Biluochun.
Xiázhōu Bìfēng (峡州碧峰, Xiázhōu Bìfēng): Hubei green tea with chestnut profile and charcoal finish drying. Similar in nutty note, but Bifeng is thinner, more delicate; Xue Lü is more powerful and dense thanks to large-leaf Yunnan raw material.
Lúshān Yúnwù (庐山云雾, Lúshān Yúnwù): Jiangxi mountain green tea from analogous misty terroir. Yunwu gives soft, tender, floral-sweet profile when brewed at 80 °C. Xue Lü at higher extraction temperature reveals completely different scale — dense, oily, with palpable “bony” structure characteristic of Yunnan large leaf.

In conclusion:

Cangshan Xue Lü is a tea of contrasts: snow-capped peaks and green slopes, tender down and dense taste, high-altitude freshness and deep oiliness. It was born at the crossroads of cultures — the tea tradition of the Bai people, heritage of the Ancient Tea Horse Road and craftsmanship of Xiaguan Factory. Among China’s green teas, this is one of the few brewed with nearly boiling water and revealing itself not through delicacy, but through power and volume. For lovers of Yunnan tea, familiar primarily with pu-erh and dianhong, Xue Lü will be an unexpected and vivid discovery — proof that Yunnan large leaf can be not only dark and red, but also dazzlingly green.
