Yangtian Xue Lü

Yangtian Xue Lü is a modern named green tea from Henan Province, created in the early 1980s at the intersection of Chinese and Japanese tea traditions. It is produced on the northern slopes of Mount Nainai Dian in the Dabie Mountains, where mountain spring meets the snow cover of the peaks, and tea gardens are immersed in the diffused light of cloud mist. Distinguished by its flat, slender leaf form with abundant down and persistent orchid aroma.

1. Classification and Origin:

2. History and Cultural Significance:

• History:

Tea cultivation in the Gushi area has deep roots. In the “Classic of Tea” (《茶经》, Chájīng) by Lù Yǔ (陆羽) it is said: “Among the teas of Huainan, tea from Guangzhou ranks first” (淮南茶以光州上). Ancient Guangzhou Prefecture (光州) included the territory of modern Gushi County, which testifies to the Tang (7th–9th centuries) tradition of tea production in these places. According to local legend, Tāng Emperor Lì Shìmín (李世民), being wounded, was healed by drinking tea from Mount Dàbié and granted it tribute status (贡茶).

The northern slope of Nainai Dian was traditionally called “Guangzhou Da Shan Cha” (光州大山茶) — “big mountain tea from Guangzhou.” However, the tea received its current poetic name much later. In 1847 (27th year of the Daoguang reign, 道光), Qīng jǐnshí (状元) and outstanding botanist Wǔ Qījūn (吴其濬, 1789–1847), a native of Gushi, returning home after retirement, visited the mountain during the Gǔyǔ (谷雨, “Grain Rain”) season. Looking upward, he saw the snow-white cover of the peak and emerald green of tea bushes at the foot and composed the line: “He feng yong xue yang tian lü, fang ming ying chun gai shi xiang” (和风咏雪仰天绿，芳茗迎春盖世香) — “In warm wind snow is praised, green faces heaven; fragrant tea greets spring, its aroma conquers the world.” Hence arose the name “Yangtian Xue Lü” — “Heaven-gazing snowy green.”

The modern tea in its current form was created in 1982–1984 by agronomist Zhú Xueyi (朱学义), who combined elements of Japanese sencha (煎茶) technology and Xīhú Lóngjǐng (西湖龙井), creating a unique flat profile with special shaping technique. In 1986, at a provincial evaluation with participation of specialists from Hunan Agricultural University, Anhui and Zhejiang agricultural universities, the tea was recognized as an “innovative famous tea of Henan” (河南省创新名茶). In 2003 the trademark was registered; in 2004 national geographical indication was obtained.

• Name:

“Yang” (仰) — “to raise one’s gaze, look upward”; “tian” (天) — “heaven”; “xue” (雪) — “snow”; “lü” (绿) — “green.” Literally: “Looking to heaven — snowy green.” The name conveys a spring picture: at the foot of the mountain emerald tea buds unfold, while the peak is still covered with snow. The poetics of the name traces back to the poetic line by Qing scholar Wu Qijun.

• Cultural significance:

Gushi is one of the “root” counties of Chinese southward migration: from here come the ancestors of a significant part of the population of Fujian and Taiwan (recorded in the formula “Guangzhou Gushi”, 光州固始). The tea culture of Gushi is at the crossroads of two great tea traditions — to the west of the county they produce Xìnyáng Máo Jiān (信阳毛尖), to the east — Liú An Guā Piàn (六安瓜片). Yangtian Xue Lü occupies an intermediate niche between them, combining Dabie Mountain terroir with authorial technology. The tea is considered a “visiting card” of the county alongside Jiǔhuáshān Máo Jiān (九华山毛尖) — another local famous tea.

3. Botanical Description and Raw Material:

• Variety / Cultivar: Base — local small-leaf population variety (本地群体小叶种, běndì qúntǐ xiǎoyè zhǒng) Camellia sinensis var. sinensis. Auxiliary cultivars: Fúdǐng Dàbái Chá (福鼎大白茶, Fúdǐng Dàbái Chá) and Longjing 43 (龙井43, Lóngjǐng 43). Age of main plantations — over 30 years. Leaves elliptical, thick and fleshy; weight of 100 shoots of “one bud — one leaf” standard is about 45 g. Tenderness period (持嫩期) in the local variety is extended by 7–10 days compared to standard cultivars.
• Picking: Spring picking — primary. Optimal window — from Qīngmíng (清明) to Gǔyǔ (谷雨), i.e., approximately from early to late April. Early spring picking (before Qingming) — most valuable.
• Picking standard: Supreme grade (特级) — single buds or bud with one barely opened leaf (单芽或一芽一叶初展); First grade (一级) — bud with one leaf (一芽一叶); Second grade (二级) — bud with two leaves and opened leaves (一芽二叶及开展叶).
• Raw material requirements: Shoots must be full, tender, uniform, with abundant down. Hand picking is mandatory for highest grades.

4. Terroir and Cultivation Features:

The tea gardens of Yangtian Xue Lü are located on the northern slope of Mount Nǎinai Diān (奶奶殿) — one of the peaks of the Dàbié Mountains (大别山), in southeastern Henan Province, on the border with Anhui Province. The key feature is precisely the northern exposure: reduced insolation slows shoot growth, which increases accumulation of amino acids and aromatic substances.

• Growing altitude: About 653 m above sea level (main plantations); Nainai Dian peak — higher.
• Climate: Transitional from subtropical to temperate monsoon. Average annual temperature 12.5–15.5 °C; daily temperature range — more than 10 °C. Number of foggy days — over 102 per year. Diffused light (散射光) predominates, stimulating accumulation of L-theanine and amino acids.
• Soils: Micro-acidic yellow sandy soils (微酸性黄沙土), pH 4.5–5.6. Rich in humus, as well as zinc and selenium. Soils developed on ancient shales and known by the local name “gray-ash earth” (香灰土, xiānghuī tǔ) — ideal substrate for tea bushes.
• Ecology: Forest cover — 87.6%. Use of chemical fertilizers and pesticides is prohibited; the farm has European organic certification. Territory recognized as national ecological demonstration zone.

5. Production Technology:

Yangtian Xue Lü technology is an authorial development of the 1980s, synthesizing elements of classical Longjing pan-firing and Japanese sencha. Hand processing combines more than ten techniques, including “scooping” (捞, lāo), “shaking” (抖, dǒu), “leading” (带, dài), “scattering” (撒, sā), “rolling” (搓, cuō) and “pressing” (压, yā). The principle of “combining strong and weak fire” (文火武火并施) — from Japanese tradition.

• Spreading-withering (摊青, tān qīng): Freshly picked leaves are spread in a thin layer for 4 hours for partial moisture loss and initial aroma formation.

• Kill-green fixation (杀青, shāqīng): Performed in a cast iron pān (铁锅) at about 120 °C. Temperature lower than most classical chao-qing teas — this allows preserving leaf tenderness and delicate aroma.

• Shaping (做形, zuòxíng): Key stage, giving the tea its characteristic flat form. Combines two techniques: “rolling into strips” (搓条, cuō tiáo) — drawing leaf between palms to form straight strips; and “casting strips” (甩条, shuǎi tiáo) — light shaking for straightening and leveling. Precisely at this stage the tea acquires its flat, slender, slightly glossy form with protruding down.

• Initial drying — mao huo (毛火): Heating at 80 °C; reducing moisture content to intermediate level.

• Final drying — zu gan (足干): Prolonged low-temperature drying at 60 °C to moisture content ≤7%. Ensures aroma fixation and storage stability.

6. Organoleptic Characteristics:

• Dry leaf appearance: Flat, slender, straight (扁平挺秀), with abundant silvery down (显毫). Color — oily green, fresh (翠绿油润). Leaf even, uniform in size. Visually resembles Longjing, but with more pronounced down.

• Dry leaf aroma: Clean, high, with distinct orchid note (兰花香, lánhuā xiāng). Spring picking has additional chestnut note (栗香).

• Liquor aroma: Persistent, long-lasting, with predominant orchid note. Aroma height is one of the main distinguishing features: according to geographical indication standard, aroma is characterized as “qing gao chijiu” (清高持久) — “clean, elevated, long.”

• Taste: Fresh and mellow-rich (鲜醇, xiān chún), with pronounced sweet-rich fullness (甘厚, gān hòu). Aftertaste — long returning sweetness (回甘持久). Bitterness and astringency are absent with proper brewing. Liquor body — medium, with velvety texture.

• Liquor color: Tender green with light yellowish undertone (嫩绿微黄), clean and clear (清澈明净).

• Spent leaves: Tender green, bright (嫩绿明亮), even, lively (匀齐鲜活). Leaves open completely, demonstrating integrity and tenderness.

7. Chemical Composition:

Yangtian Xue Lü is distinguished by high content of water extract and amino acids — result of northern exposure and high-mountain microclimate.

• Water extract (水浸出物): ≥44% — one of the highest indicators among famous green teas of China, which ensures extraordinary “density” and richness of liquor.
• Amino acids (氨基酸): ≥4.6%. High L-theanine content is due to diffused light and daily temperature range over 10 °C.
• Polyphenols (茶多酚): ≥23% (for first grade and above). Moderate level compared to southern green teas — precisely this explains mildness and absence of bitterness.
• Alkaloids: Caffeine — within typical limits for green tea (2.5–4%); theobromine, theophylline — in trace amounts.
• Vitamins: Vitamin C — 100–500 mg/100 g (significant variation depending on season and grade). B vitamins, vitamin E.
• Minerals: Zinc and selenium — in elevated concentrations, due to soil mineralization of Dabie Mountains.
• Essential oils: Orchid aromatic profile is formed by linalool, geraniol and nerolidol.
• Composition feature: High ratio of amino acids to polyphenols (amino acids/polyphenols ≈ 0.2) — one of the markers of “mild,” “sweet” green teas.

8. Health Properties:

• Antioxidant protection: High vitamin C content (up to 500 mg/100 g) provides effective neutralization of free radicals and cellular membrane support.
• Detoxification and radioprotection: Vitamin C promotes elimination of heavy metals (lead, cadmium) and reduction of radiation exposure consequences.
• Tonic effect: Combination of caffeine and L-theanine provides mild, steady alertness without anxiety — state of calm concentration.
• Lipid metabolism support: Catechins stimulate fat oxidation; moderate regular consumption may contribute to cholesterol reduction and gallstone disease prevention (through stimulation of cholesterol conversion to bile acids).
• Cardiovascular system: Tea polyphenols are linked to blood pressure reduction and improved vascular elasticity.
• Cognitive functions: L-theanine improves brain alpha rhythms, promoting mental clarity and concentration.
• Skin condition: Antioxidant complex (vitamin C + catechins) supports collagen synthesis and protection from photoaging.
• Digestion: Moderate tannin content gently stimulates peristalsis without mucosal irritation.

9. Brewing:

• Water temperature: 85–90 °C. Boiling water above 90 °C is categorically not recommended — high temperature destroys theanine and intensifies bitterness.
• Tea amount: 3 g per 150 ml (1:50 ratio).
• Vessels: Glass tumbler (玻璃杯) — optimal for observing leaf form and liquor color; white porcelain gaiwan (盖碗) — for fuller aroma development and layered taste evaluation.
• Process:

1. Warm glass or gaiwan with hot water, drain.
2. Apply top-down method (上投法, shàngtóufǎ): first pour water into glass, then carefully lower tea — leaves will slowly sink, opening.
3. Pour water smoothly, along vessel wall — this prevents down dispersion and liquor clouding.
4. First infusion — 1 minute. Each subsequent — with 20-second increase.
5. Tea withstands 7 or more infusions (耐泡度7次以上).
6. For gaiwan: use medium steeping time 15–20 seconds on first infusions, increasing by 5–10 seconds.

• Tip: When brewing in glass, you can add water when about 1/3 volume is consumed — this maintains stable concentration.

10. Storage:

• Conditions: Airtight light-proof packaging (aluminum foil + tin or pewter container). Store in refrigerator at 0–5 °C.
• Period: Most expressive in first 6–12 months. Fresh tea is recommended to “awaken” (醒茶) 7 days after opening — keep in air in light-protected place to dissipate residual “fire” taste. After opening — consume within 10 days.
• Tea enemies: Light, moisture, heat, foreign odors, oxygen. Do not store near strongly scented products.
• Note: For short-term storage (up to 2 months) cool dark place at room temperature is acceptable.

11. Price and Counterfeits:

• Price guidelines (China domestic market, 2023–2024):

  • Supreme grade (特级): ≥500 yuan per jin (500 g) — pure buds or bud + one leaf, bright orchid aroma.
  • First grade (一级): 200–500 yuan per jin — bud + one leaf, clean aromatics, rich taste.
  • Second grade (二级): less than 200 yuan per jin — accessible everyday option.

• How to avoid counterfeits:

  • Check leaf form: Authentic Yangtian Xue Lü is flat, slender, with pronounced gloss and abundant silvery down. Imitations often have looser or irregular structure.
  • Evaluate aroma: Real tea has persistent orchid aroma without “hay,” grassy or sour smell.
  • Check liquor: Tender green with yellowish undertone, clean and clear. Cloudy or dark green liquor is sign of substitution or improper storage.
  • Pay attention to price: Suspiciously low price for “supreme grade” is sign of substitution with cheaper raw material.
  • Choose seller: Prefer products with geographical indication marking (国家地理标志产品) from Gushi County. Brands tied to specific Yangtian Wa tea farms are reliable.

12. Interesting Facts:

• Tea named by verse: Yangtian Xue Lü is one of the few Chinese teas whose name directly traces to a poetic line. The verse author — Wǔ Qījūn (吴其濬), the only jinshi (状元, “first in state examination”) in all history of Henan Province in the Qing era, and also author of the monumental botanical work “Zhiwu mingshi tukao” (《植物名实图考》) — one of the most important botanical atlases of 19th-century China.

• Synthesis of two traditions: When creating the tea in 1982–1984, agronomist Zhu Xueyi consciously borrowed elements of Japanese sencha technology (gentle processing, emphasis on amino acid preservation) and combined them with classical Chinese pan-firing. This makes Yangtian Xue Lü a rare example of intercultural synthesis in tea production.

• Climatic crossroads: Gushi County is located precisely on the zero January isotherm — climatological boundary between subtropics and temperate zone of China. This transitional character gives local teas unique ambivalence: mildness of southern teas with density and persistence of northern ones.

• “Botanical status”: In 2015, Yangtian Xue Lü entered the registry of 11 Gushi products receiving national-level ecological origin protection — first such precedent in China at county level.

• Neighborhood of titans: Gushi tea gardens are located exactly between two famous tea regions: Xìnyáng (信阳) to the west with its Máo Jiān and Luán (六安) to the east with its Gua Pian. Yangtian Xue Lü thus grows “in the shadow of the great,” but offers a completely different flavor profile.

13. Comparison with Other Green Teas:

• Xìnyáng Máo Jiān (信阳毛尖, Xìnyáng Máojiān): Closest geographical neighbor, one of the “Ten Famous Teas of China.” Both are from Henan, both with abundant down. However, Mao Jian has rounded, finely twisted form (细圆光直), while Xue Lü has flat and slender. Mao Jian aromatics are more chestnut-beany; Xue Lü has pronounced orchid note. Xinyang terroir is somewhat higher (800–1000 m), but without such bright northern exposure effect.

• Xīhú Lóngjǐng (西湖龙井, Xīhú Lóngjǐng): Reference flat green tea. Yangtian Xue Lü leaf form visually resembles Longjing, but Xue Lü has more pronounced down (毫), while best Longjings are smooth. Longjing aromatics are chestnut-beany, more “roasted”; Xue Lü is more floral (orchid). Longjing is chao-qing (wok firing); Xue Lü is hongqing (heat drying), giving softer, more “airy” aroma.

• Tàipíng Hòu Kuí (太平猴魁, Tàipíng Hóukuí): Anhui flat green tea, also from Dabie Mountain zone, but significantly large-leaf. Hou Kui is the “biggest” of flat green teas; Xue Lü is conversely miniature. Hóu Kuí aromatics are orchid (兰花香), which relates it to Xue Lü, but Hou Kui taste is more oily and “voluminous.”

• Luán Guà Piān (六安瓜片, Liù’ān Guāpiàn): Eastern neighbor in Dabie Mountains. Unique in being produced from leaf blade without bud. Form — rolled “melon seed slice.” Aromatics — more “heated,” chestnut. Absence of bud gives less tender but more saturated taste.

• Jiǔhuáshān Máo Jiān (九华山毛尖): Second famous tea of Gushi. Produced at same latitudes but by technology closer to classical Xinyang Mao Jian. Form — rounded, twisted; aroma — chestnut. If Jiuhuashan Mao Jian is “traditional” representative of Gushi teas, then Yangtian Xue Lü is “authorial innovator.”

In Conclusion

Yangtian Xue Lü is one of the most poetic and technologically original green teas of central China. Born at the crossroads of great tea regions, it absorbed the mildness of Dabie Mountain terroir, orchid refinement of aroma and flat elegance of form reminiscent of Longjing, but with its own character. This tea will especially suit those who value in green tea not astringency and “green” brightness, but velvety sweetness, long aftertaste and that special transparency given only by mountain mists at the junction of south and north. Its name is a poetic postcard: snowy peak, emerald shoots and gaze turned to heaven.
