Lingyun Green Tea

Lingyun Green Tea (凌云绿茶, Língyún lǜchá) is a green tea from Lingyun County (凌云县, Língyún Xiàn) in Baise City (百色市, Bǎisè Shì), Guangxi Zhuang Autonomous Region (广西壮族自治区), produced from the unique cultivar Lingyun Baimao (凌云白毫种, Língyún Báiháo Zhǒng), known as Huacha No. 26 (华茶26号) — one of the first 21 national tea cultivars approved by the Ministry of Agriculture of the PRC in 1965. This is a semi-arbor large-leaf variety (小乔木大叶种, xiǎo qiáomù dàyè zhǒng): trees reach 6–9 m in height, buds are large, fleshy, with abundant white down — hence “白毫” (báiháo, “white down”) in the name. The biochemical profile is impressive: polyphenols — 35.6%, catechins — 182.92 mg/g — indicators comparable to Yunnan large-leaf teas and among the highest for Chinese green teas. The Lingyun Baimao cultivar is unique in that all six tea classes (六大茶类) can be produced from it — “one tree, a thousand transformations” (一茶千化, yī chá qiān huà). In 1915, the tea received a second medal at the Panama International Exhibition (巴拿马国际食品博览会二等奖), and in 2005 — geographical indication protection of the PRC. By 2024, the tea garden area of the county reached 112,500 mu (≈7,500 ha), annual production — 8,326 tons, total product value — 716 million yuan.

1. Classification and Origin:

• Type: Green tea (绿茶, lǜchá), unfermented. Produced in several forms: Baimao Wang (白毫王, Báiháo Wáng, “King of White Down”) — straight “needles” (针形, zhēnxíng); Lingluochun (凌螺春, Língluóchūn) — spiral twist (螺形); Baimao Yinzhen (白毫银针, Báiháo Yínzhēn) — single bud. Technology — pan-firing with proprietary method of “slow triple pan-firing at low temperature” (低温慢炒三青, dīwēn mànchǎo sān qīng) and final heating for “aroma enhancement” (复香, fùxiāng).

• Category: National Geographical Indication Product of the PRC (国家地理标志产品, 2005; trademark — 2016). Cultivar Huacha No. 26 — one of the first 21 national tea cultivars (1965). National first-class tea cultivar (国家级茶树良种, 1984). Second medal at the Panama International Food Exhibition (巴拿马国际食品博览会二等奖, 1915). Multiple international competition winner: gold in red and yellow tea categories, silver — green tea (II and III International Famous Tea Competitions). Lingyun — one of the first 20 national demonstration counties for safe tea production (全国无公害茶叶生产示范基地县, 2001).

• Origin: China, Guangxi Zhuang Autonomous Region (广西壮族自治区, Guǎngxī Zhuàngzú Zìzhìqū), Baise City (百色市, Bǎisè Shì), Lingyun County (凌云县) and Leye County (乐业县, Lèyè Xiàn). Production core — Cenwanglaoshan (岑王老山, Cénwáng Lǎoshān) and Qinglongshan (青龙山, Qīnglóng Shān) mountain ranges, 800–1,500 m.

• Geographic coordinates: Approximately 24°06′–24°36′ N, 106°23′–106°55′ E.

2. History and Cultural Significance:

• 300+ years of cultivation. Tea plantations in Lingyun have been documented since the early Qing Dynasty (清, 1644–1912). The area has groups of wild and semi-wild tea trees several centuries old, and individual wild specimens in the protected zones of Cenwanglaoshan reach 8.5 m in height and are estimated to be over 1,000 years old. During the Qianlong era (乾隆, 1736–1795), local tea became “gongcha” (贡茶, gòngchá) — “tribute tea” for the imperial court, confirming its early reputation.

• 1915 — Panama International Exhibition. At the famous Panama Exhibition of 1915 — one of the largest international trade events of the early 20th century — tea from Lingyun received a second medal (二等奖). This became one of the first international recognitions for tea from Guangxi and put Lingyun Baimao on the world tea cultivation map.

• 1965 — Huacha No. 26. The Ministry of Agriculture of the PRC and the Tea Research Institute of the Chinese Academy of Agricultural Sciences (中国农业科学院茶叶研究所) conducted a systematic evaluation of the country’s tea cultivars. Lingyun Baimao was included among the first 21 national tea cultivars and received registration number Huacha 26 — one of the few Guangxi varieties in this elite list.

• 1984 — National first-class variety. The China Tea Cultivar Certification Committee (中国茶树良种审定委员会) granted Lingyun Baimao the status of national excellent variety (国家级茶树良种) of the first category. In the same year, the variety was presented at the All-China Conference on Agricultural Zoning and included in the “Collection of Excellent Tea Cultivars of China” (《中国茶树优良品种集》).

• 2005 — Geographical indication. The State Administration of Quality of the PRC (国家质检总局) approved protection of “Lingyun Baimao Tea” as a geographical indication product.

• Cultural significance. Baise is a city of “red” (revolutionary) history: it was here in December 1929 under the leadership of Deng Xiaoping (邓小平, Dèng Xiǎopíng) that the Baise Uprising (百色起义, Bǎisè Qǐyì) occurred, becoming one of the key episodes in the Communist Party of China’s struggle. Lingyun Green Tea is the “green” symbol of this “red” land. Lingyun is one of the poorest counties in Guangxi, and the tea industry has become a key tool in poverty alleviation: by 2024, tea gardens occupy 112,500 mu, providing employment for tens of thousands of Zhuang and Yao (瑶族) minority families. The Lingyun Baimao cultivar, capable of producing all six tea classes, is known as “one tree, a thousand transformations” (一茶千化) — a unique versatility unmatched in Asia.

3. Botanical Description and Raw Material:

• Cultivar: Lingyun Baimao Zhong (凌云白毫种, Língyún Báiháo Zhǒng), also known as Huacha No. 26 (华茶26号) — Camellia sinensis var. sinensis (according to alternative classification — var. pubilimba, to be clarified). Semi-arbor (小乔木, xiǎo qiáomù) type. Large-leaf (大叶类, dàyè lèi), medium-maturing (中生种, zhōngshēng zhǒng). Propagation — by seeds (有性繁殖系, yǒuxìng fánzhí xì). Botanical characteristics:

  • Height — up to 6–9 m with free growth; maintained by pruning to 1–1.5 m on plantations.
  • Habit — semi-spreading (半张开, bàn zhāngkāi), relatively sparse branching.
  • Leaves — large, elliptical, horizontal or slightly drooping. Dark green, matte, with raised surface (叶面隆起). Pronounced venation. Abaxial (lower) side — densely pubescent.
  • Buds — large, fleshy, with abundant long white down (茸毫长而密). Weight of 100 buds with two leaves (一芽三叶百芽重) — average 99 g — significantly more than medium-leaf varieties.
  • Spring shoot — in Lingyun begins developing in mid-March; peak harvest (一芽三叶) — late March to early April.
  • Flowering — November-December, sparse fruiting.

• Biochemistry (according to Tea Research Institute of CAAS):

  • Amino acids — 3.36%.
  • Polyphenols — 35.6% — one of the highest indicators among green teas.
  • Catechins — 182.92 mg/g — exceptional antioxidant potential.
  • Caffeine — 4.91%.
  • Water-extractable substances — high.

• Grades:

  • Superior (特级): One bud + one leaf, down ≥90%, chestnut aroma with “board” notes (板栗香). For Baimao Wang form — straight “needles”.
  • First (一级): One bud + two leaves, tight twist.
  • Second (二级): Mature leaf, mass market line.

4. Terroir and Cultivation Features:

• Relief. Lingyun is a mountainous county at the junction of the Yunnan-Guizhou Plateau and Guangxi Basin. Relief — karst (喀斯特, kāsītè) mountains, deep canyons, mountain streams. Tea gardens are located mainly on the slopes of Cenwanglaoshan and Qinglongshan ranges, at 800–1,500 m elevation — in the cloud belt. Characteristic landscape type — “canyon stream tea gardens” (峡谷溪涧茶园): rows of tea trees stretch along mountain streams in narrow canyons, receiving natural shading and increased humidity.

• Climate: Subtropical monsoon (亚热带季风气候). Average annual temperature — 19–23°C. Annual precipitation — 1,700–1,800 mm. Cloudy and foggy days — over 100 per year. Daily temperature variation significant, especially in the 1,000–1,500 m zone. Air humidity — ≥90% in the cloud belt.

• Soils: Developed on volcanic rocks (火山岩风化土, huǒshān yán fēnghuà tǔ) of Cenwanglaoshan and Qinglongshan ranges. Acidic (pH 4.5–5.5). Organic content — 3.0–4.5‰. Rich in mineral elements. Good drainage due to rocky base.

• Ecology: Forest coverage — 76.7% — one of the highest among tea counties in Guangxi. Water resources — mountain streams, 1st class purity. Production core — Yuhong Township (玉洪乡, Yùhóng Xiāng) and Jiayou Town (加尤镇, Jiāyóu Zhèn). Biodiversity — high: karst forests support rich fauna and flora, natural enemies of tea pests sufficient to minimize chemical protection.

• Scale. By 2024: tea gardens — 112,500 mu (≈7,500 ha), annual dry tea production — 8,326 tons, total product value — 716 million yuan. Lingyun is the largest tea county in Guangxi and one of the most important in South China.

5. Production Technology:

Proprietary technology “低温慢炒三青” (dīwēn mànchǎo sān qīng) — “slow triple pan-firing at low temperature for maximum preservation of downy aroma”. The entire process is conducted with bamboo and wooden tools (全程竹木器具加工, quánchéng zhú mù qìjù jiāgōng) — metal does not contact the leaf, preventing oxidative darkening and metallic taste.

• Spreading (摊青, tān qīng): Relatively long (摊放时间较长) — more prolonged than for most green teas. Allows large, fleshy buds to evenly lose moisture and form aromatic precursors.

• “Kill-green” (杀青, shā qīng): Temperature — 180–200°C. Fixation degree — intentionally deeper (杀青程度偏重): this destroys residual enzyme activity in large-leaf material with high polyphenol content (35.6%), preventing browning. Immediately after fixation — fan cooling (扇风散热, shàn fēng sàn rè) to prevent “yellowing” (防闷黄, fáng mèn huáng) — a crucial technique preventing spontaneous transition to yellow tea category.

• Rolling (揉捻, róuniǎn): Initial shape formation — for Baimao Wang — straight “needles”, for Lingluochun — spiral twist.

• “Slow triple pan-firing” (炒干 — 三青, chǎo gān — sān qīng): Key stage. Low temperature, slow process, triple cycle: pan-firing → cooling → re-pan-firing → cooling → final pan-firing. “Small fire, long time, multiple slow tosses” (小火长时间多次慢抛). Goal — maximum preservation of white down (白毫) and formation of deep chestnut aroma (板栗香) without scorching. This method distinguishes Lingyun Green Tea from other large-leaf green teas.

• Final heating / “aroma restoration” (复香, fùxiāng): Gentle heating to “lift” aroma and bring moisture to ≤6%.

6. Organoleptic Characteristics:

• Dry leaf appearance: Depends on form. Baimao Wang — straight “needles” with abundant white down, resembling silver rods (形似银针, xíng sì yínzhēn). Lingluochun — tight spirals. Color — green with abundant white down (条索紧结、白毫显露, tiáosuǒ jǐnjié, báiháo xiǎnlù). Five famous characteristics: “色翠、毫多、香高、味浓、耐泡” — “emerald color, abundant down, high aroma, rich taste, durability”.

• Dry leaf aroma: Chestnut (板栗香, bǎnlì xiāng) — primary and most characteristic. Pure (清香, qīngxiāng). “Downy” (毫香, háoxiāng) — subtle “corn-like” note characteristic of abundantly downy teas.

• Infusion aroma: Chestnut — deep, warm, persistent. “Downy” — sweetish note appearing upon cooling. Aroma persists in the cup for a long time, and spent leaves retain aroma even after several days — a rare characteristic.

• Taste: Fresh (鲜爽, xiānshuǎng). Rich and mellow (浓醇, nóngchún) — full-bodied infusion with pronounced structure, atypical for green teas and due to high polyphenol content (35.6%). Returning sweetness (回甘) — stable, long-lasting. Durability — 4–5 full infusions without losing character, also atypical and explained by large-leaf raw material.

• Liquor color: Tender green, clear and transparent (嫩绿清澈, nèn lǜ qīngchè). On second-third infusion — with light yellow tint.

• Tea bottom (spent leaves): Olive-green, tender, lustrous (青橄榄色、匀嫩亮润, qīng gǎnlǎn sè, yún nèn liàng rùn). Leaves — large, whole, with visible down. When brewed in a glass cup — leaves descend “standing”, like spring shoots — a spectacular effect.

7. Chemical Composition:

• Polyphenols (茶多酚): 35.6% — one of the highest indicators among Chinese green teas, comparable to Yunnan large-leaf teas (Dianlü, Pu’er Sheng). High content is due to large-leaf variety, subtropical climate with intense insolation, and volcanic soils stimulating phenolic compound synthesis.

• Catechins (儿茶素, ér chá sù): 182.92 mg/g — exceptional antioxidant potential. Main fractions — EGCG (epigallocatechin gallate), EGC, ECG, EC. For comparison: typical medium-leaf green tea contains 80–120 mg/g catechins.

• Amino acids (氨基酸): 3.36% — moderate indicator, characteristic of large-leaf varieties of southern origin. Polyphenol to amino acid ratio (酚氨比) — high (about 10.6:1), determining a “rich, structured” taste profile with noticeable astringency and long aftertaste.

• Caffeine (咖啡碱): 4.91% — elevated, providing pronounced tonic effect.

• Vitamins: Vitamin C — preserved thanks to “slow triple pan-firing” at low temperature. B-group vitamins (B₁, B₂, B₃). Vitamin E.

• Mineral substances: Potassium, magnesium, manganese, zinc, iron, fluorine. Volcanic substrate provides expanded mineral profile.

• Unique feature: The combination of large-leaf nature, 35.6% polyphenols and 182.92 mg/g catechins with 3.36% amino acids creates a profile atypical for green tea and approaching “pu’er-like” — with emphasis on body, structure and durability rather than lightness and “freshness”.

8. Health Benefits:

• Powerful antioxidant action. Catechins 182.92 mg/g — one of the highest concentrations among green teas. EGCG — the main catechin — is recognized as one of the strongest natural antioxidants, neutralizing free radicals and slowing cellular aging.

• Pronounced tonic effect. Caffeine 4.91% — above average for green tea. Provides alertness, improved concentration and working memory. Combined with L-theanine — without nervousness.

• Digestive support. High polyphenol content (35.6%) stimulates digestive enzyme secretion, supports healthy intestinal microflora.

• Cardioprotection. Catechins and polyphenols participate in cholesterol level regulation, reduce LDL oxidation, support vascular elasticity.

• Lipid metabolism support. EGCG activates thermogenesis and fatty acid oxidation — potential metabolic support.

• Antimicrobial action. Catechins suppress growth of various pathogenic bacteria, including Streptococcus mutans (caries) and Helicobacter pylori.

• Immune strengthening. Complex of polyphenols and vitamins C, E provides immunomodulating action.

• Cognitive support. L-theanine stimulates brain α-waves, improving attention and relaxation without sedation.

9. Brewing:

• Water temperature: 80–85°C. Large-leaf material with high polyphenol content requires moderate temperature to avoid excessive bitterness.

• Tea amount: 3 g per 150 ml (1:50 ratio).

• Teaware: Glass cup (for observing the “dance” of downy needles). Gaiwan. Porcelain teapot.

• Process:

  1. Warm the vessel with hot water, discard.
  2. Add tea.
  3. Upper infusion method (上投法, shàng tóu fǎ): first pour water, then add tea. Large, fleshy buds of Lingyun Baimao slowly descend and “stand” in the cup — a spectacular effect resembling spring shoots.
  4. First infusion — 30–45 seconds.
  5. Pour the infusion.
  6. Repeated infusions — 4–5 infusions, each +15–30 seconds. Durability — one of the “five famous qualities” (耐泡): even on the fifth infusion, taste retains character.

10. Storage:

• Airtight packaging (aluminum bag with vacuum air extraction), refrigerator 0–5°C. Shelf life — up to 12 months.

• For long-term storage — freezing (-18°C) in vacuum packaging.

• Tea enemies: moisture, foreign odors, light, high temperature. Guangxi’s subtropical climate — high humidity; storage without refrigeration undesirable.

11. Price and Counterfeits:

• Price category: Superior grade (Baimao Wang, one bud + one leaf) — from 500–1,500 yuan/500 g depending on producer and year. Lingluochun — 200–600 yuan/500 g. Mass market — from 100 yuan/500 g.

• How to avoid counterfeits:

  • GI marking. Authentic tea is marked with “凌云白毫茶” or “凌云绿茶”.
  • Bud size. Authentic Lingyun Baimao — large, fleshy buds with abundant white down. Small and thin buds — sign of substitution with medium-leaf variety.
  • Aroma. Chestnut (板栗香) + “downy” (毫香) note. Absence of burnt, sour smell.
  • Durability. Authentic tea withstands 4–5 infusions. If taste “drops out” after two — possible substitution.
  • Price. Superior grade cannot cost less than 300 yuan/500 g. Cheap offers under “Lingyun Baimao” brand raise suspicion.

12. Interesting Facts:

• 1915 — Panama medal. Lingyun Baimao — one of the first teas from Guangxi to receive international recognition. The 1915 Panama Exhibition also made famous Xi Hu Longjing, Xinyang Maojian and other great Chinese teas.

• Huacha No. 26 — trees up to 9 meters. Semi-arbor variety — unusually large for green tea. Most Chinese green teas are produced from medium-leaf shrub varieties 1–1.5 m tall; Lingyun Baimao with free growth reaches the height of a three-story building.

• “One tree, a thousand transformations” (一茶千化). Lingyun Baimao — one of the few (and, according to some data, the only one in Asia) cultivars from which all six tea classes are produced: green, red, white, yellow, dark (hei cha) and oolong. Red tea from Lingyun has received gold medals at international competitions.

• Canyon gardens. Tea rows in Lingyun are located along mountain streams in canyons (峡谷溪涧) — a unique landscape type providing natural shading, increased humidity and wind protection.

• Catechins 182.92 mg/g. One of the highest indicators among Chinese green teas — comparable to Yunnan large-leaf teas, traditionally considered “champions” in catechins. For comparison: typical Longjing contains 100–130 mg/g catechins.

13. Comparison with other green teas:

• Yunnan large-leaf green tea (Dianlü, 滇绿, Diānlǜ). Both are large-leaf, with high polyphenol and catechin content. Dianlü — from Yunnan large-leaf variety (C. sinensis var. assamica); Lingyun — from Lingyun Baimao (C. sinensis var. sinensis, semi-arbor). Dianlü — more astringent, “rough”; Lingyun — with pronounced chestnut aroma and “downy” softness. Both — powerful in antioxidant potential.

• Guiping Xishan Tea (桂平西山茶, Guìpíng Xīshān Chá). Also Guangxi green tea, from small-leaf variety. Xishan — light, floral; Lingyun — rich, chestnut. Xishan — from lowland hills (200–500 m); Lingyun — from mountain canyons (800–1,500 m). Different scales: Lingyun — 112,500 mu, Xishan — significantly smaller.

• Dongting Biluochun (洞庭碧螺春, Dòngtíng Bìluóchūn). Lingluochun (凌螺春) — spiral form of Lingyun — intentionally named by analogy with Biluochun. Both — spiral, downy. Biluochun — small-leaf, floral-fruity; Lingluochun — large-leaf, chestnut. Biluochun — 60,000–80,000 buds/kg; Lingluochun — significantly fewer due to large buds.

• Baisha Green Tea (白沙绿茶, Báishā Lǜchá). Hainan green tea with unique geology (meteorite crater). Both — from non-standard geological zones (volcanic rocks for Lingyun, meteorite crater for Baisha). Baisha — tropical, year-round vegetation; Lingyun — subtropical, spring peak. Baisha — small-leaf; Lingyun — large-leaf.

Conclusion:

Lingyun Green Tea is a tea from “red” Baise, born on the volcanic soils of Qinglongshan canyons, from semi-arbor trees up to nine meters tall, with catechins of 182.92 mg/g and a Panama medal from 1915. Cultivar Huacha No. 26 — one of China’s first national tea varieties — yields tea with rich chestnut aroma, “downy” softness and antioxidant potential rivaling Yunnan giants. Five famous qualities — emerald color, abundant down, high aroma, rich taste, durability — and the ability of one tree to produce six tea classes make Lingyun Baimao one of China’s most versatile and underappreciated cultivars.
