Gēlǎo yù cuì

Gēlǎo Yù Cuì (仡佬玉翠, Gēlǎo yù cuì) — “Jade Emerald of the Gelao People” — is a flat green tea from Dàozhēn Gēlǎo and Miáo Autonomous County (道真仡佬族苗族自治县, Dàozhēn Gēlǎozú Miáozú Zìzhìxiàn), Guizhou Province. The name honors the indigenous Gēlǎo ethnic group (仡佬族, Gēlǎozú) — one of the most ancient peoples of Southwest China, considered descendants of the ancient Ba-Shú peoples (巴蜀) and connected to the legendary Yèláng Kingdom (夜郎). The tea is grown on siliceous soils naturally enriched with two rare antioxidant microelements — selenium (Se, 2.5 mg/kg) and strontium (Sr, 7.0 mg/kg) — making “Yu Cui” a flagship representative of the category “富硒锶绿茶” (“green tea rich in selenium and strontium”). Flat, straight tea leaves resembling sword blades (如剑刃), with abundant silvery down — the brand’s signature feature, honored with a gold award at the Shanghai International Tea Culture Festival (2003) and a silver award at the International Tea Competition (2005).

The county is located at the junction of Guìzhōu Province and Chóngqìng Municipality (重庆), in the northeastern part of the province, on the northern slope of the Guizhou Plateau.

• Geographic coordinates: Approximately 28°52′ N, 107°36′ E.

2. History and Cultural Significance:

• History:

The tea history of Dàozhēn County is inseparably linked with the Gēlǎo people (仡佬族) — one of the most ancient ethnic groups of southern China. According to historical sources, the Gēlǎo are descendants of the ancient Liáo people (僚, Liáo) and, according to several scholarly hypotheses, trace back to the Yèláng Kingdom (夜郎, Yèláng) — a powerful kingdom of Southwest China that existed from the 4th century BCE to the 1st century CE. The current population of Gelao in China is approximately 550,000, with the overwhelming majority living in Guizhou, predominantly in Dàozhēn and Wuchuan counties (务川). Daozhen is the largest compact settlement area of the Gelao, where they constitute a significant portion of the county’s population.

“Records of the Grand Historian · Biographies of Merchants and Industrialists” (《史记·货殖列传》, “Shǐ Jì · Huòzhí Lièzhuàn”) by Sima Qiān (司马迁) records that already during Emperor Wu’s reign (武帝, 141–87 BCE), tea from the area of modern Daozhen and Wuchuan was transported for sale to Gansu. Lù Yǔ (陆羽) noted in “The Classic of Tea”: “黔中生思州、播州、费州、夷州……往往得之，其味极佳” — “In Qianzhong [= Guizhou] tea grows in Sizhou, Bozhou [= Zunyi], Feizhou, Yizhou… it is often obtained, and its taste is excellent.” Bozhou (播州) is the ancient name for the Zunyi region, which includes Daozhen. Thus, tea cultivation in this region has been documented since the Han era — over 2000 years.

The modern “Gelao Yu Cui” brand was created in the 1990s by tea specialists from Daozhen County, combining traditional processing methods with modern standardization. In 2003, the tea won a gold award at the Shanghai International Tea Culture Festival, and in 2005 — silver at an international competition. In 2015, the trademark “仡佬玉翠” received the status of “Famous Trademark of Guizhou Province.”

An important milestone was the registration in 2024 of a new tea cultivar “Yucui Chashu” (玉翠茶树, GPD茶树(2024)350068), developed by the Fujian Academy of Agricultural Sciences specifically for Zunyi conditions. The creation of a proprietary cultivar marks the brand’s maturity, transitioning from borrowed varieties to purposeful varietal provision.

• Name:

“Gelao” (仡佬) is the self-designation of the Gelao people. Including the ethnonym in the tea name pays tribute to the indigenous people of Daozhen County and their tea traditions. This is one of the few Chinese teas whose name directly references a specific ethnic minority. “Yu” (玉) — “jade,” the highest aesthetic compliment in Chinese culture: jade embodies purity, nobility, coolness, and moral perfection. “Cui” (翠) — “emerald,” describes the color of the dry leaf.

• Cultural significance:

For Daozhen County — the largest compact settlement of the Gelao people — tea is not only an economic product but also a symbol of ethnic identity. Gelao tea culture is unique and includes two important rituals. The first — “youcha” (油茶, yóuchá, “oil tea”): an ancient beverage made from tea leaves fried in animal fat with salt and spices, serving simultaneously as food and drink, restoring strength after field work. The second — “San Yaotai” (三幺台, Sān Yāotái, “Three Small Tables”): a three-stage ceremonial guest reception ritual where tea occupies a central place alongside snacks and “main dishes.” The “San Yaotai” ritual is included in the registry of China’s intangible cultural heritage.

3. Botanical Description and Raw Material:

• Variety / Cultivar:

  • Mingshan 213 (名山213, Míngshān 213) and Mingshan 131 (名山131) — medium-leaf cultivars from Sichuan (Meishan/Mingshan area, Ya’an City), providing the foundation for standard production. Camellia sinensis var. sinensis, adapted to subtropical highland conditions.
  • Yucui Chashu (玉翠茶树) — new cultivar registered in 2024 (GPD茶树(2024)350068). Developed by the Fujian Academy of Agricultural Sciences specifically for the soil and climatic conditions of Zunyi. Distinguished by large, fleshy buds, abundant silvery down, and high “tenderness retention” (持嫩性强).

• Harvest: Spring harvest — primary. Pre-Qīngmíng tea (明前茶) — most valuable. Standard: highest grade — complete bud or one bud with barely opened leaf, silvery down ≥80%; first grade — one bud with one leaf; second — one bud with two leaves.

4. Terroir and Cultivation:

• Climate: Subtropical humid monsoon. Average annual temperature — 15.6°C. Annual precipitation — 1070 mm. Frost-free period — 287 days. Relative humidity — 81%. Cloud cover — 80%. Extended frost-free period and high cloud cover ensure slow, steady accumulation of aromatic and flavor compounds in the leaf.

• Elevation: 500–800 m a.s.l. (hilly terrain at the junction of the Guizhou Plateau and Sichuan Basin).

• Soils: Siliceous yellow soils (硅质黄壤, guīzhì huángrǎng), pH 5.5–7.5, rich in organic matter. Key uniqueness — dual microelement enrichment: selenium (Se) — 2.5 mg/kg, strontium (Sr) — 7.0 mg/kg. This combination is due to the geochemical characteristics of the region’s siliceous deposits and is extremely rare in global tea cultivation. Strontium — a microelement that promotes bone tissue strengthening — is practically absent in significant concentrations in other tea terroirs.

• Ecology: Forest cover — 44%. Cloud cover — 80%. The area is located far from major industrial centers, ensuring high ecological purity of the raw material. Guizhou overall ranks first among China’s provinces in tea plantation area (approximately 7 million mu as of 2022), and the “Guizhou Green Tea” standard (贵州绿茶) — China’s first provincial geographical indicator for green tea — sets a high quality bar: water-extractable substances ≥40%, organoleptic standard — “翡翠绿、嫩栗香、浓爽味” (“jadeite color, tender chestnut aroma, rich and fresh taste”). Daozhen, despite its remoteness, fully meets this standard.

5. Production Technology:

“Flat hot-air drying” technology (扁形烘青) with unique stages “搭扁” (flattening) and “磨锅” (pot polishing):

• Spreading (摊放, tānfàng): 3–5 hours. Leaf loses excess moisture, light surface fermentation begins.

• Fixation — “kill-green” (杀青, shāqīng): 280–320°C for 3 minutes — high-temperature pan-firing, significantly exceeding the standard for most green teas (usually 120–180°C). Rapid “killing” of oxidase at extremely high temperature — characteristic feature of the Guizhou school.

• Wind selection (风选, fēngxuǎn): Removal of small fragments and dust.

• Shaping — “strip arrangement” (理条, lǐtiáo): 80–120°C for 15 minutes. Initial formation of the tea leaf’s linear structure.

• Flattening — “搭扁” (dā biǎn): 150–180°C for 15 minutes — key proprietary stage, absent in most green teas. Forms the flat “sword-like” shape (扁平挺直) by which Gelao Yu Cui is unmistakably recognizable.

• “Pot polishing” (磨锅, mó guō): 80–100°C for 30 minutes — final polishing of the tea leaf surface. Imparts oily luster (油润) and smoothness.

• Drying (烘干, hōnggān): 150°C for 40 minutes.

• Heating — “aroma lifting” (提香, tíxiāng): 80–90°C for 40 minutes. “Three dryings, three heatings” technology (三烘三提, sān hōng sān tí): first heating removes “grassiness,” second fixes the chestnut aroma base, third establishes “cold aroma” — a delicate cool note characteristic of high-altitude Guizhou teas.

6. Organoleptic Characteristics:

• Dry leaf appearance: Flat, straight, smooth tea leaves (扁直光滑), resembling sword blades (如剑刃). Color — emerald green with oily luster (翠绿油润). Highest grade has abundant silvery down covering ≥80% of the bud surface.

• Dry leaf aroma: Clean, high, persistent (清香持久). Characteristic mountain “ecological aroma” (山场气息, shānchǎng qìxī) — specific note of Guizhou highland teas, reminiscent of moist morning forest. Highest grade has additional “downy aroma” (毫香, háoxiāng), distantly reminiscent of young corn.

• Liquor aroma: Clean, medium height, with chestnut base and “cold” finish. “Cold aroma” — result of the third heating in “三烘三提” technology.

• Taste: Fresh and brisk (鲜爽, xiānshuǎng), with quick returning sweetness (回甘迅速). Body — mellow and rich (醇厚, chúnhòu), exceeding ordinary flat green teas, explained by the richness of internal substances accumulated in Se-Sr soils. Aftertaste — prolonged, mineral, with light coolness.

• Liquor color: Tender yellow, clear and bright (嫩黄透亮, nèn huáng tòu liàng) — for highest grade. First and second grades — more saturated yellow-green.

• Spent leaves: Tender green, uniform. Leaves unfold from “sword-like” form, revealing down.

7. Chemical Composition:

• Selenium (Se): 2.5 mg/kg — exceptionally high level, one of the maximum among Guizhou green teas. Selenium is an essential microelement, part of glutathione peroxidase, a key antioxidant enzyme of the organism.

• Strontium (Sr): 7.0 mg/kg — rare microelement for tea terroirs. Stable (non-radioactive) strontium participates in bone tissue mineralization and stimulates osteoblast activity.

• Amino acids (氨基酸): Elevated content — characteristic feature of high-altitude Guizhou teas grown under high cloud cover and diffused light conditions.

• Polyphenols (茶多酚): Typical level for high-altitude Guizhou teas. “Guizhou Green Tea” standard (贵州绿茶) requires water-extractable substances ≥40%.

• Vitamins: Vitamin C, B-group vitamins — standard set for quality green tea.

• Minerals: Se, Sr, K, Mg, Zn. Dual Se + Sr enrichment — unique geochemical feature of Daozhen soils, not found in comparable concentrations in other Guizhou teas. Potassium (K) and magnesium (Mg) are present in standard amounts for green tea and contribute to maintaining electrolyte balance.

• Composition uniqueness: The chemical uniqueness of Gelao Yu Cui is determined not so much by the content of classical tea components (polyphenols, amino acids, caffeine) as by its mineral profile: dual Se and Sr enrichment moves the tea from the “beverage” category to the “functional product” category. Selenium and strontium are not synthesized by the plant — they come exclusively from soil, making Daozhen’s terroir an irreplaceable factor.

8. Health Properties:

• Dual antioxidant action: Selenium (Se) is part of glutathione peroxidase, while polyphenols (catechins) directly neutralize free radicals — two mechanisms working synergistically.

• Bone tissue support: Stable strontium (Sr) stimulates osteoblast differentiation (cells forming bone tissue) and suppresses osteoclast activity — unique benefit practically absent in other teas.

• Tonic effect: Caffeine combined with L-theanine provides “gentle tone” — increased concentration without sharp nervous excitement.

• Refreshing action: High amino acid content and “cold aroma” create subjective sensation of coolness.

• Digestive support: Tannins and catechins stimulate digestive enzyme secretion.

• Immune support: Selenium and vitamin C jointly strengthen immune response, supporting NK-cell activity.

• Antibacterial action: Catechins (EGCG, ECG) show bacteriostatic activity.

• Thyroid support: Selenium is a cofactor of deiodinase, the enzyme converting thyroxine (T4) to active triiodothyronine (T3). Regular selenium intake from tea helps maintain normal thyroid function.

• Cardioprotective action: Polyphenols help reduce LDL cholesterol levels and maintain vascular wall elasticity. Selenium additionally protects vascular endothelium from oxidative damage.

• Cognitive support: L-theanine crosses the blood-brain barrier, promoting alpha-wave generation in the brain and improving attention concentration.

9. Brewing:

• Water temperature: 85–90°C.

• Tea amount: 4 g per gaiwan of ~120 ml capacity (tea should occupy approximately ¼ of vessel volume).

• Vessels: Glass tumbler — recommended for observing “floating swords” (tea leaves vertically suspended in water create spectacular view). Gàiwǎn (盖碗) 120–150 ml — for short infusions.

• Process:

  1. Warm vessel with hot water, drain.
  2. Add 4 g tea.
  3. Apply “bottom pouring method” (下投法, xiàtóufǎ): pour ⅓ volume water for rinsing and leaf opening.
  4. Add water to 7/10 volume.
  5. First infusion — 5 seconds.
  6. Infusions 2–4 — add +5 seconds to each subsequent.
  7. Up to 5 infusions when using gaiwan.

10. Storage:

• Container: Airtight vacuum packaging of aluminum foil.
• Temperature: Refrigerator, 0–5°C.
• Storage period: 12 months with airtight storage. After opening — 1 month (flat leaf shape increases air contact area, accelerating oxidation).
• Tea enemies: Moisture, light, foreign odors, heat.

11. Price Range and Counterfeits:

• Price range: Highest grade (特级) — ~320 yuan per 100 g (~1600 yuan per 500 g). First grade — ~180 yuan per 250 g (~360 yuan per 500 g). Second grade — more affordable.

• Cost factors: Raw material grade (highest — only buds with ≥80% down), harvest season, Se and Sr content (confirmed by laboratory analysis).

• How to avoid counterfeits:

  • Buy from “Hongfu Tea Industry” (宏福茶业, Hóngfú Cháyè) — brand creator company, or “Pinpin Xiang” (品品香, Pǐnpǐn Xiāng) — having production base in Daozhen.
  • Evaluate shape: authentic Yu Cui — flat, straight, “sword-like,” with oily luster. Counterfeits — loose, without characteristic geometry.
  • Check down: highest grade should have abundant silvery down (≥80%).
  • Evaluate liquor: authentic highest grade — tender yellow, clear. Dark or turbid liquor — sign of poor quality raw material or counterfeit.
  • Request Se and Sr content certificate — authentic Yu Cui from Daozhen has documentary confirmation of geochemical composition.

12. Interesting Facts:

• “First ancestor” people. Gēlǎo (仡佬族) are considered descendants of ancient Liáo peoples (僚) and, according to several hypotheses, connected to the legendary Yèláng Kingdom (夜郎). Precisely the Gelao ancestors, according to “Records of the Grand Historian” (《史记》), already during Han traded tea from the region of modern Daozhen.

• Se + Sr — double shield. The combination of high selenium (2.5 mg/kg) and strontium (7.0 mg/kg) in one tea — geochemical rarity due to unique siliceous soils of Daozhen. For comparison: the famous “锌硒茶” (zinc-selenium tea) from neighboring Fenggang contains selenium but not strontium.

• Proprietary cultivar (2024). Registration of “Yucui Chashu” variety (GPD茶树(2024)350068) — sign of brand maturity: transition from borrowed Sichuan cultivars to proprietary variety optimized for specific soil and climatic conditions.

• “Three tables” — Gelao tea banquet. “San Yaotai” ritual (三幺台) — three-stage guest reception where first “table” — tea with nuts and sweets, second — “oil tea” (油茶) with snacks, third — full feast. Included in intangible cultural heritage list.

• 280–320°C: extreme fixation. “Kill-green” temperature for Gelao Yu Cui — one of the highest among Chinese green teas (usually 120–180°C). Quick high-temperature pan-firing in 3 minutes — signature technique of Guizhou school.

• “Sword-like” tea leaves. Flat shape “如剑刃” (resembling sword blade) — result of unique “搭扁” stage (flattening at 150–180°C), absent in most flat green teas’ technology, including Longjing.

13. Comparison with Other Green Teas:

• West Lake Lóngjǐng (西湖龙井, Xīhú Lóngjǐng): Both are flat green teas, but technologies are fundamentally different. Longjing — pan-fired (炒青), “pressed” by palm against wok wall; Yu Cui — hot-air dried (烘青), “flattened” in separate “搭扁” stage. Longjing — “beany” aroma (豆香); Yu Cui — “mountain ecological aroma” with chestnut base. Longjing grows at 150–250 m elevation; Yu Cui — 500–800 m.

• Fenggang Zinc-Selenium Tea (凤冈锌硒茶, Fènggāng Xīnxī Chá): “Zinc-selenium tea” from neighboring Fenggang County, also part of Zunyi. Both are “mineral” teas, but Fenggang contains zinc (Zn) and selenium (Se), while Daozhen — selenium (Se) and strontium (Sr). Fenggang — predominantly twisted; Yu Cui — flat.

• Méitán Cuìyá (湄潭翠芽, Méitán Cuìyá): Famous flat green tea from Meitan (Zunyi). Both flat, both from Zunyi region, but Cuiya uses Longjing-type pan-firing technology, while Yu Cui — hot-air drying technology with “搭扁” stage. Cuiya — more “sweet” and “soft”; Yu Cui — more “mineral” and “rich.”

• Dūyún Máojiān (都匀毛尖, Dūyún Máojiān): Main “name” tea of Guizhou, included in UNESCO’s intangible cultural heritage list (as part of “Traditional Tea Processing Techniques in China,” 2022). Twisted, downy, with “fish hook” shape (鱼钩形). Fundamentally different shape (twisted vs flat), different flavor profile (“brothy freshness” vs “mineral richness”), but comparable terroir level. Duyun Maojian is produced in southern Guizhou (Duyun City, Qiannan Buyi and Miao Autonomous Prefecture), while Yu Cui — in northeastern province, determining differences in soil composition and microclimate.

• Green Gem (绿宝石, Lǜbǎoshí): Modern proprietary tea from Guizhou, created by tea expert Mou Yìngshū (牟应书). Uses coarser raw material — one bud + two-three leaves — and shaped into pellets. Fundamentally differs from Yu Cui in raw material grade, shape, and price category, but shares “Guizhou” quality standard (水浸出物 ≥40%).

In Conclusion:

Gelao Yu Cui is a tea with rare “triple origin”: ethnic (Gelao people — one of the most ancient ethnic groups of the Southwest, whose ancestors traded tea during Han, two millennia before the modern brand appeared), geochemical (soils simultaneously enriched with selenium and strontium — combination without analogs among Chinese green teas, turning each cup into a source of two rare antioxidant microelements), and aesthetic (flat “sword-like” tea leaves of jade color, born from the unique “搭扁” stage at 150–180°C — shape impossible to confuse with Longjing or Meitan Cuiya). In the cup — freshness with quick returning sweetness and rich body uncommon to most flat green teas, with “cold aroma” in the finish — result of triple heating “三烘三提.” Tea for those who value not only taste but cultural depth — from three-stage “San Yaotai” ritual to siliceous soil mineralogy, from legendary Yelang Kingdom to registration of proprietary “Yucui Chashu” cultivar in 2024. Daozhen is not just a point on Guizhou’s map, but a place where tea tradition, geochemistry, and ethnic identity are fused into a single jade-emerald leaf.
