Guìlín Máo Jiān

Guìlín Máo Jiān (桂林毛尖, Guìlín máo jiān) is a hongshao-type green tea (烘青绿茶) from the capital of karst landscapes — the city of Guilin, Guangxi Zhuang Autonomous Region. The tea was created in the early 1980s by the Guangxi-Guìlín Tea Research Institute (广西桂林茶叶科学研究所) at the foot of Mount Yáoshān (尧山, Yáo Shān) — in the historic landscape of Míng dynasty tombs of the Jingjiang princes (靖江王墓群). The uniqueness of this tea lies in its selenium content, which exceeds the average indicator of ordinary green tea by 7 times (0.146 μg/g), which is related to the geochemical characteristics of Yaoshan soils. The tea received an award from the Ministry of Agriculture of the PRC for “excellent quality” (1989) and a gold medal at the Bangkok International Exhibition of Chinese Agricultural Products (1993).

1. Classification and Origin:

• Type: Green tea (绿茶, lǜchá), non-oxidized. Belongs to hot air-dried green teas (烘青绿茶, hōngqīng lǜchá) with strip-shaped (条索形, tiáosuǒ xíng) leaf form.

• Category: Regional famous tea of Guǎngxī (广西名茶). Award from the Ministry of Agriculture of the PRC “优质产品” (1989). Gold medal at the Bangkok International Exhibition (1993, “中国优质农产品展览会”). Production is regulated by the local Guangxi standard “Technical Regulations for Processing Guilin Mao Jian” (《桂林毛尖茶加工技术规程》, 2014).

• Origin: China, Guǎngxī Zhuāng Autonomous Region (广西壮族自治区, Guǎngxī Zhuàngzú Zìzhìqū), Guìlín City (桂林市, Guìlín Shì). Core production area — Mount Yáoshān (尧山, 909 m) in Qīxīng (七星区) and Diecai (叠彩区) districts. Tea gardens are located on the territory of the scenic area of Míng dynasty Jingjiang prince tombs (明代靖江王墓群风景区).

• Geographic coordinates: Approximately 25°18′ North latitude, 110°20′ East longitude.

2. History and Cultural Significance:

• History: Guilin Mao Jian is a relatively young tea, created during the era of “tea renaissance” of the 1980s.

  Creation (early 1980s). The tea was developed by specialists from the Guangxi-Guìlín Tea Research Institute (广西桂林茶叶科学研究所), located at the foot of Mount Yaoshan. The technology combined Fujian cultivars (Fuyun 6, Fuding Damao) with local ecological advantages — selenium soils and subtropical microclimate.

  Recognition (1989–1993). In 1989, Guilin Mao Jian received the title “Famous Tea of Guangxi” (广西名茶) and an award from the Ministry of Agriculture of the PRC for “excellent quality.” In 1993 — gold medal at the Bangkok International Exhibition of Chinese Quality Agricultural Products (中国优质农产品展览会) — an event that went beyond the domestic Chinese market.

  Standardization (2014 — present). In 2014, a local Guangxi standard was adopted, regulating the complete processing cycle. Full mechanization of production was introduced while preserving manual operations at final stages (for premium grades). Work began on developing proprietary local varieties — “Guilü 1” (桂绿1号) and “Yaoshan Xiulü” (尧山秀绿), included in the registry of state tea cultivars.

• Name:

  • “Guilin” (桂林) — “Cinnamon Forest” — a famous city whose karst landscapes entered the saying “Guilin’s mountains and waters are the best under Heaven” (桂林山水甲天下). The tea’s name deliberately connects the product with one of China’s most recognizable tourist brands worldwide.
  • “Mao Jian” (毛尖) — “Downy Tips” — classic designation for high-quality green tea from tender buds and young leaves covered with white down. The term “mao jian” in Chinese tea nomenclature is associated with such great teas as Xinyang Mao Jian and Duyun Mao Jian.

• Cultural significance: Guilin Mao Jian is produced in one of China’s most scenic places — at the foot of Mount Yaoshan, on the territory of the Míng dynasty Jingjiang prince tomb complex (靖江王墓群) — the largest preserved Ming necropolis in southern China. Tea gardens framing ancient tombs create a unique combination of natural, historical, and agricultural landscape. Guilin City, receiving millions of tourists annually, promotes local tea as part of the region’s “gastronomic map.”

3. Botanical Description and Raw Material:

• Variety / Cultivar: Several cultivars of Camellia sinensis var. sinensis are used:

  • Fuyun 6 (福云6号, Fúyún Liùhào) — main cultivar (~60% share). Extra-early variety (特早生种): harvest begins in late February, 30 days earlier than in tea regions of Jiangsu and Zhejiang. Polyphenol content — 23.4%, amino acids — 3.9%. Suitable for producing both flat and spiral green teas.
  • Fúdǐng Dàmáo (福鼎大毫, Fúdǐng Dàháo) — cultivar with abundant down, giving the tea silvery luster and “downy aroma” (毫香).
  • Guilü 1 (桂绿1号, Guìlǜ Yīhào) and Yaoshan Xiulü (尧山秀绿, Yáoshān Xiùlǜ) — local improved varieties included in the registry of state cultivars. Distinguished by increased resistance to cold and drought.

• Harvest: Thanks to the Fuyun 6 variety and Guilin’s subtropical climate (temperature >15°C already in late February), harvest begins a month earlier than in Jiangnan. This advantage provides a market window for “first spring tea” (早春茶). Spring raw material is distinguished by maximum amino acid accumulation and pronounced freshness.

• Harvest standard:

  • Premium grade (特级): full bud or one bud with barely opened leaf. Completely manual harvest.
  • First grade (一级): one bud with one leaf. Mechanization + manual finishing.
  • Second grade (二级): one bud with two leaflets in initial stage.

• Raw material requirements: Shoots uniform, tender, with abundant white down (白毫 ≥90% for premium grade). Processing — on the same day.

4. Terroir and Cultivation:

• Climate: Guilin is located in the subtropical monsoon climate zone. Average annual temperature — 19.1°C. Annual precipitation — 1733 mm. Significant daily temperature fluctuations in spring. During spring tea harvest period — frequent rains and fogs, high proportion of diffused light.

• Growing altitude: About 300 m above sea level. Low compared to mountain terroirs of Guizhou and Sichuan, but compensated by low latitude (25° N) and high humidity.

• Soils: Yellow-red soils (黄红壤, huáng hóng rǎng) with pH 5.0–5.5. Organic matter content — 1.38–1.88%. Key uniqueness — natural enrichment with selenium and zinc: Se content in tea leaf — 0.146 μg/g (7 times higher than ordinary green tea).

• Ecology: Forest cover of Mount Yaoshan — 67%. Complete absence of industrial pollution sources in the production zone (territory of natural and historical reserve).

5. Production Technology:

Guilin Mao Jian is hongshao lücha (烘青绿茶), i.e., green tea dried with hot air. Technology feature — final operation of “repeated heating for aroma enhancement” (复香, fùxiāng) and blending of varieties to optimize flavor profile.

• Harvest (采摘 — cǎi zhāi): Manual or semi-mechanized harvest in morning hours.

• Spreading (摊放 — tān fàng): Shoots are spread on bamboo sieves for 3–6 hours. Moisture loss — ~5%.

• Kill-green (杀青 — shāqīng): Rotary drum at 260°C, duration — 4–5 minutes. High temperature ensures rapid and complete enzyme inactivation.

• Rolling (揉捻 — róuniǎn): Method “light → heavy → light” (轻—重—轻 alternation). Formation of tight strip structure of tea leaves.

• Primary drying (毛火 — máo huǒ): Hot air at 120°C. Removal of main moisture mass.

• Final drying (足火 — zú huǒ): Temperature reduced to 80°C. Bringing to moisture content ≤6%.

• Repeated heating — “aroma enhancement” (复香 — fùxiāng): Key final operation: heating at 80°C for 15 minutes. This stage significantly enhances aroma persistence and ensures precise moisture control (≤6%).

• Technology features: Multi-variety blending (多品种拼配) is applied: Fuding Damao (for downy aroma) + Fuyun 6 (for flavor richness and density). Ratio is selected for each grade.

6. Organoleptic Characteristics:

• Dry leaf appearance: Tight, straight strips (条索紧细匀直), with abundant silvery-white down (白毫显露). Color — emerald green (翠绿).

• Dry leaf aroma: Clean, high (清香), with delicate “young” note (嫩香) for premium grade and chestnut (栗香) for first grade. Cold cup retains aroma for more than 15 minutes.

• Liquor aroma: Clean, persistent, with pronounced freshness. Best batches — with light floral undertone.

• Taste: Fresh (鲜爽), mellow (醇和, chúnhé), with moderate polyphenol content ensuring balance without excessive astringency. Returning sweetness (回甘) — persistent. Aftertaste — with “cool” note (高山冷韵, “high-mountain cold rhyme”).

• Liquor color: Turquoise-green, clear and transparent (碧绿清澈) for premium grade; yellow-green — for second grade.

• Spent leaves (wet leaves): Tender green, bright (嫩绿明亮), uniform. Shoots unfold in complete “bouquets” (匀整成朵).

7. Chemical Composition:

• Polyphenols: ~23.4% (data for main cultivar Fuyun 6). Moderate indicator ensuring mellow taste.
• Amino acids (including L-theanine): ~3.9% — high indicator. Amino acids determine the characteristic “freshness” and “briskness” of Guilin Mao Jian.
• Selenium (Se): 0.146 μg/g — 7 times higher than average for ordinary green teas. Key marker of Yaoshan terroir.
• Fluorine: Content 30% higher than in similar hongshao teas — according to researchers’ claims, this enhances tooth enamel protection.
• Water-extractable substances: ≥45%.
• Caffeine: Moderate content.
• Vitamins: Vitamin C, B-group vitamins.
• Minerals: Se, Zn, K, Mg, F.

8. Health Properties:

• Selenium deficiency compensation: Se 0.146 μg/g — significant additional Se source.
• Antioxidant action: Polyphenols ~23% + organic Se — synergy of two antioxidant protection systems.
• Tooth protection: Increased fluorine content (+30% above norm) enhances enamel resistance to acid erosion.
• Tonic effect: Caffeine + L-theanine — gentle alertness.
• Digestive support: Catechins normalize intestinal microflora.
• Metabolic support: Catechins promote blood sugar level control (water-extractable ≥45%).

9. Brewing:

• Water temperature: 80°C (cool boiling water ~2 minutes). Tender buds are sensitive to overheating.
• Tea amount: 3 g per 150 ml (1:50 ratio).
• Vessel: Glass tumbler (for observing “tea dance”) or white porcelain gaiwan (for aroma concentration).
• Process:
  1. Warm vessel with hot water.
  2. Add tea.
  3. Pour 1/3 volume of water for “rinsing” (润茶, 3 minutes).
  4. Add water to 7/10 volume. First infusion — 1 minute.
  5. Tea withstands 3 infusions.

10. Storage:

• Airtight packaging, protection from light, moisture and odors.
• Optimal — refrigerator at 0–5°C.
• After opening — consume within 3 months (protection from polyphenol oxidation).

11. Market and Price Range:

• Price category: Middle and upper segment of Guangxi green teas. Premium grade (特级, manual harvest) — from 600 yuan per 500 g. First grade — 200–400 yuan. Second grade — mass market tea.
• Authenticity Identification:
  • Purchase products from Guangxi-Guilin Tea Research Institute or authorized partners.
  • Authentic tea — even, straight strips with abundant white down and clean fresh aroma.
  • Liquor should be clear, turquoise-green.
  • Ability to withstand 3 full infusions — sign of quality raw material.

12. Recommended Sources:

• Primary source: Guangxi-Guìlín Tea Research Institute (广西桂林茶叶科学研究所) and authorized distributors.
• Retail: Specialized tea shops in Guilin, online platforms with certification.
• Tourist purchases: Tea shops in Guilin scenic areas, but verify authenticity.

13. Interesting Facts:

• Tea among Ming tombs. Guìlín Máo Jiān tea gardens are located on the territory of the Míng dynasty Jingjiang prince tomb complex (靖江王墓群) on Mount Yaoshan — the largest preserved Ming necropolis in southern China (300+ tombs). Tea literally grows “in the shadow of imperial crypts.”

• A month earlier than Jiangnan. Thanks to the Fuyun 6 variety and Guilin’s subtropical climate, harvest begins in late February — 30 days earlier than in the celebrated tea regions of Zhejiang and Jiangsu. This gives Guilin Mao Jian a unique market advantage as “first spring tea.”

• Selenium × 7. Se content in Guilin Mao Jian leaf — 0.146 μg/g, which is 7 times higher than the average indicator of ordinary green teas. Reason — geochemical characteristics of Mount Yaoshan soils, formed from ancient sedimentary rocks rich in selenium.

• Bangkok-1993. The gold medal at the 1993 Bangkok International Exhibition became one of the first international awards for green tea from Guangxi — a region historically associated more with Liùbǎo black tea (六堡茶) than with green teas.

14. Comparison with Other Guangxi Green Teas:

• Língyún Green Tea (凌云绿茶): Also from Guangxi, high-mountain. Guilin Mao Jian — more “downy,” Se-enriched, from Yaoshan karst terroir.

• Xīshān Tea (西山茶): Also from Guilin, historical tea from Mount Xishan. Guilin Mao Jian — modern artisanal, scientific approach to cultivar selection.

• Xìnyáng Máo Jiān (信阳毛尖): Henan. Classic “Mao Jian,” rolled, downy. Guilin — similar category, but from subtropical karst.

In Conclusion:

Guilin Mao Jian is a tea born in one of the most scenic places on the planet: at the foot of Mount Yaoshan, among karst peaks and Ming tombs, on soils naturally saturated with selenium. It does not claim a thousand-year history — it was created by scientists in the 1980s — but confidently proved that a scientific approach to cultivar selection and technology can produce results competing with centuries-old traditions. In the cup — pure freshness with a “downy” note, gentle sweetness and long cool aftertaste. Tea for those who value the combination of scientific precision and natural generosity.
