Yuèguāng jīn zhī

Yueguang Jin Zhi is a Dianhong gongfu-class tea representing the modern premium line of Yunnan red teas. The name, literally “Moonlight, golden branches,” combines poetic imagery with an emphasis on abundant golden tips — the signature feature of this tea. Produced in Fengqing and Jinggu counties of Yunnan Province from large-leaf raw material Camellia sinensis var. assamica, it demonstrates the classic Dianhong floral-fruity, honey-caramel profile with a full, rounded taste and impressive resistance to multiple infusions.

1. Classification and Origin:

• Type: Chinese red tea (black tea) (红茶, hóngchá), fully oxidized.
• Category: Diānhóng (滇红, Diānhóng) — Yunnan red tea school based on large-leaf raw material. Belongs to the gōngfū black tea type (工夫红茶, gōngfū hóngchá). Diānhóng is among the four famous red teas of China alongside Qíhóng (祁红), Zhènghé Gōngfū (政和工夫), and Chuānhóng (川红).
• Origin: China, Yúnnán Province (云南省, Yúnnán Shěng). Main production areas — Fèngqìng County (凤庆县, Fèngqìng Xiàn), Líncāng City (临沧市), as well as Jǐnggǔ County (景谷县, Jǐnggǔ Xiàn), Pu’er City (普洱市). Both areas are located in the Lancang River (Mekong) basin, in the zone of historical habitat of wild tea trees.
• Geographic coordinates: approximately 24°35′ N, 99°55′ E (center of Fengqing County).

2. History and Cultural Significance:

• History: Yueguang Jin Zhi is a product of the modern stage of Yunnan red tea development. To understand its context, it is necessary to turn to the history of Dianhong as a whole.

  Yunnan is a region with the most ancient tea tradition on Earth: in Fengqing County, in Xiāngzhúqīng village (香竹箐, Xiāngzhúqīng), grows the greatest known cultivated tea tree, approximately 3,200 years old. However, red tea began to be produced here only in the 20th century. In 1938, during the height of the anti-Japanese war, tea master Féng Shàoqiú (冯绍裘, Féng Shàoqiú) arrived in Fèngqìng on assignment from the China Tea Company (中茶公司) to organize a new source of export red tea — the eastern tea provinces were cut off by war. Seeing the mighty tea trees with large, fleshy leaves and abundant down, Feng produced trial batches of red and green tea. The red tea caused a sensation: golden tips, rich ruby liquor, aroma not inferior to Qihong, with density and persistence unattainable for small-leaf varieties. Thus in 1939, Dianhong was born. The first batch — about 500 dan (25 tons) — was sent through Hong Kong to the London exchange, where it was sold at a record price.

  In 1958, the highest grade Diānhóng was designated as official diplomatic tea (外交礼茶) — it was supplied to PRC embassies worldwide. In 1986, during Queen Elizabeth II’s visit to Yunnan, she was presented with “Dianhong Jinya” (滇红金芽, “Dianhong golden buds”), which the queen took as a gift and kept in a glass vessel as a rarity. In 2022, Dianhong production technology was included in UNESCO’s Representative List of Intangible Cultural Heritage as part of “Traditional tea processing techniques and associated social practices in China.”

  The specific name “Yueguang Jin Zhi” appeared in the 2010s as a commercial product of “Qicai Yunnan” company (七彩云南, Qīcǎi Yúnnán) — one of the largest Yunnan tea brands specializing in pu-erh and high-quality Dianhong. The tea is positioned as premium-class Dianhong with emphasis on golden buds and floral-fruity profile.

• Name: “Yueguang” (月光) means “moonlight” — a poetic image referring to the silvery-white down of buds, reminiscent of lunar radiance. “Jin” (金) — “golden,” denotes the abundance of golden tips in the finished tea. “Zhi” (枝) — “branch,” a metaphor for thin, cord-like tea leaves. Together, the name creates an image of exquisite tea with a contrast of silver and gold — visually striking and memorable.

• Cultural significance: Yueguang Jin Zhi belongs to the new wave of Yunnan red teas oriented toward the domestic Chinese market, where Dianhong is experiencing a renaissance after decades of predominantly export focus. Fengqing, the key production area, holds the official title “Birthplace of Dianhong” (世界滇红之乡, Shìjiè Diānhóng zhī Xiāng) and actively develops tea tourism. The tea has been awarded at tea exhibitions and is positioned as a “red treasure” (红茶珍品) in the “Qicai Yunnan” assortment.

3. Botanical Description and Raw Material:

• Variety / Cultivar: Yunnan large-leaf type (Camellia sinensis var. assamica). Main cultivar — Fèngqìng Large Leaf (凤庆大叶种, Fèngqìng Dàyè Zhǒng), recognized as a national variety in 1985. This is a seed (sexual) variety, tree-type, with large, fleshy leaves and abundant bud pubescence. Characterized by high polyphenol content (up to 30–33% dry matter) and caffeine, making it ideal for red tea production. The tree can reach several meters in height; terminal buds — up to 2.5 cm. Raw material from plantation plantings of Yúnkàng series clones (云抗, Yúnkàng) and Fèngqìng series (凤庆系) may also be used.
• Harvest: Spring (March–April) — main season for premium batches; summer and autumn raw material is used for mass batches. Spring buds contain maximum amino acids and give the sweetest, most delicate profile.
• Picking standard: One bud with one leaf (一芽一叶, yī yá yī yè) — main standard for “Yueguang Jin Zhi.” For more accessible batches, one bud with two leaves is acceptable.
• Raw material requirements: Leaf must be whole, without mechanical damage, with preserved turgor. Tips — large, with dense silvery-white pubescence. Time between picking and start of withering — minimal.

4. Terroir and Cultivation Features:

Production areas are located in southwestern Yunnan, in the zone of high-mountain valleys between the Nujiang (Salween) and Lancang (Mekong) rivers. Relief — deeply dissected mountainous, with pronounced vertical climatic zonation.

• Growing altitude: 1,000–2,200 m above sea level. Main Fengqing plantations are located at altitudes of 1,200–1,800 m.
• Climate: Subtropical monsoon with mountain characteristics. Average annual temperature 18–22°C. Daily temperature fluctuations are significant — up to 15°C and more, which slows shoot growth and promotes concentration of aromatic substances. Annual precipitation — 1,200–1,700 mm. Characteristic feature — frequent morning and evening fogs: “In clear weather early morning and late evening — fogs everywhere, in cloudy weather — mountains all day in clouds” (晴时早晚遍地雾，阴雨成天满山云).
• Soils: Red and yellow soils (红壤/黄壤), acidic, pH 4.5–6.0. Deep humus layer (up to 30 cm), formed by litter from tropical and subtropical vegetation. High content of organic matter and minerals.
• Features: Yunnan is the region of greatest concentration of wild tea trees on the planet. Forested mountain slopes create natural shade and biodiverse environment, which positively affects the tea’s flavor profile. Fengqing has about 56,000 mu (≈3,700 ha) of ancient tea gardens, including 32,000 mu of plantations with trees planted before 1949.

5. Production Technology:

Classic Dianhong gongfu technology with emphasis on maximum preservation of golden tips and formation of floral-fruity aroma. Among Fengqing masters, the principle of “five passes” (初制把五关) is formulated: raw material — foundation, withering — prerequisite, rolling — key, oxidation — core, drying — guarantee.

• Picking (采摘 — cǎizhāi): Hand-picking of early spring buds with one leaf. Preferably morning after dew evaporation (9:00–11:00), when leaf moisture content is optimal.
• Withering (萎凋 — wěidiāo): Leaf is spread in thin layer on bamboo or wooden racks. Duration — 12–18 hours depending on air humidity. Goal — reducing turgor to elastic state, initial development of aromatic compounds, disappearance of grassy smell. Control: leaf easily crumples in hand and doesn’t break.
• Rolling (揉捻 — róuniǎn): Withered leaf is rolled to break cell walls and bring juice to surface. For delicate tippy raw material, light pressure is applied to preserve bud integrity. Rolling degree — until formation of characteristic thin cords.
• Oxidation/fermentation (发酵 — fājiào): Rolled leaf is laid in layer in room with controlled temperature (25–30°C) and high humidity (>90%). Time — 3–5 hours. By oxidation completion, leaf acquires reddish-copper shade, grassy smell completely disappears, fruity-honey aroma with characteristic Dianhong “malty” note forms.
• Drying (干燥 — gānzào): Two-stage: primary (毛火) at higher temperature for rapid oxidation stoppage, then final (足火) at reduced temperature for aroma fixation and moisture reduction to safe level (≤6%). Possible final light warming (提香, tíxiāng) to enhance caramel-honey notes.
• Sorting (分级 — fēnjí): Separation by fraction size, tip content, leaf integrity. For “Yueguang Jin Zhi,” fraction with maximum golden bud content is selected.

6. Organoleptic Characteristics:

• Dry leaf appearance: Thin, tightly twisted cords resembling pine needles (松针, sōngzhēn). Color — dark, with oily luster. Abundant golden tips are especially noticeable, evenly distributed in leaf mass. Overall impression — neat, uniform, elegant.
• Dry leaf aroma: Sweet, honey-like, with distinct tones of caramel and dried fruits. Background floral note — light, unobtrusive.
• Liquor aroma: Multi-layered: floral-fruity notes dominate (garden roses, ripe apricot, dried plum), in middle plane — honey, caramel. When cooling, shades of baked sweet potato and milk chocolate emerge. Aroma is persistent, maintained throughout 6–8 infusions.
• Taste: Full and rounded (醇厚, chúnhòu), with bright sweetness, freshness (甘爽, gānshuǎng) and mild astringency. Liquor body — full, velvety, with pronounced oily texture characteristic of large-leaf Yunnan raw material. Aftertaste — long, sweet (回甘, huígān), with honey and fruity overtones. Absence of bitterness — distinguishing feature of quality batches.
• Liquor color: Bright red, clear, with pronounced luster. In highest grades — with golden ring (金圈) around cup edge, indicating high theaflavin content.
• Spent leaves (wet leaves): Red-copper with orange shade, elastic, uniform. In highest grades — leaves whole, buds well distinguishable, texture soft and lively.

7. Chemical Composition:

• Polyphenols: Yunnan large-leaf raw material is champion among Chinese cultivars in polyphenolic compound content (up to 30–33% in dry leaf). During full oxidation, significant portion of catechins transforms into theaflavins (茶黄素, 0.5–1.5%), responsible for brightness and “liveliness” of liquor, and thearubigins (茶红素, 8–15%), forming color depth and velvety texture. Theaflavin to thearubigin ratio — key quality indicator: higher theaflavin proportion means brighter and “fresher” liquor.
• Amino acids: L-theanine and other free amino acids provide mildness and sweetness. Spring harvest contains higher amino acid concentration due to low growth temperatures and intensive root exchange.
• Alkaloids: Caffeine — content elevated compared to small-leaf cultivars (about 30–45 mg/g dry leaf). Theobromine and theophylline present in trace amounts.
• Vitamins: Vitamin C (partially preserved despite oxidation), B-group vitamins (B1, B2, B6), vitamin E.
• Minerals: Potassium, magnesium, calcium, manganese, zinc, iron. Deep humus layer of Yunnan soils provides rich mineral profile.
• Essential oils: Linalool, geraniol, nerol, phenylethanol, cis-3-hexenol — key components of floral-fruity aroma. Volatile aromatic compound content in Dianhong — among highest among Chinese red teas.
• Feature: High content of water-soluble extractive substances (水浸出物 ≥38–40%) — significantly higher than most small-leaf red teas, which determines taste richness and resistance to infusions.

8. Health Properties:

• Tonic effect: Elevated caffeine content in large-leaf raw material provides pronounced but mild tone due to L-theanine buffering action.
• Antioxidant protection: Theaflavins and thearubigins — powerful antioxidants helping neutralize free radicals.
• Warming action: Red tea in traditional Chinese dietology — “warm” (温性) beverage, recommended for feeling cold, in autumn-winter period and for people with “cold” constitution.
• Digestive support: Polyphenols stimulate gastric juice secretion and intestinal peristalsis; warm infusion after meals promotes comfortable digestion.
• Cardiovascular support: Theaflavins promote blood lipid profile normalization.
• Antibacterial action: Polyphenols and their oxidized forms suppress growth of several pathogenic microorganisms.
• Cognitive functions: Caffeine and theanine synergy improves concentration, reaction speed and reduces mental fatigue.
• Sensory relaxation: Warm, sweet honey-caramel aroma has relaxing effect, reducing anxiety levels.

9. Brewing:

• Water temperature: 90–95°C. For delicate tippy batches — 85–90°C; large-leaf Dianhong withstands 95°C without bitterness.
• Tea amount: 4–5 g per 100–120 ml (gongfu method); 3 g per 200–250 ml (European steeping, mug).
• Teaware: Porcelain gàiwǎn (盖碗) 100–120 ml — best choice for aroma evaluation. Glass teapot allows admiring liquor color. Dianhong suits simple mug brewing well — liquor remains mild even with prolonged leaf contact.
• Process:
  1. Warm teaware with hot water and drain.
  2. Add tea and inhale aroma of heated dry leaf.
  3. Rinse (optional): quick 1–2 second pour; for delicate tippy grades can be skipped.
  4. First infusion: 5–8 seconds. Dianhong extracts quickly due to large-leaf raw material.
  5. Subsequent infusions: increase time by 3–5 seconds.
  6. Number of infusions: 6–10; quality “Yueguang Jin Zhi” batches maintain flavor up to 8–10 infusions.
• Note: Dianhong excellently suits milk or honey addition — tea’s full body doesn’t disappear when mixed, and caramel-honey profile harmoniously complements.

10. Storage:

Store in airtight opaque container (tin can, foil bag) at temperature 10–25°C, away from light, moisture and foreign odors. Optimal consumption period — 12–24 months after production. Dense batches from mature leaf can pleasantly “round out” during 2–3 year storage: liquor becomes milder, caramel notes intensify. However, classic Dianhong is a tea of freshness, and delaying consumption is not recommended, especially for tippy grades.

11. Price and Counterfeits:

Price of “Yueguang Jin Zhi” from “Qicai Yunnan” brand — medium and above medium Dianhong price segment: approximately 300–800 yuan per 100 g depending on grade and packaging. Overall, Dianhong is one of the most accessible quality red teas of China: mass batches start from 100–200 yuan per 500 g, and premium tippy ones — from 500 to 3,000 yuan.

• How to avoid counterfeits:
  1. Purchase tea from authorized brand dealers or verified tea shops. When buying “Yueguang Jin Zhi” — check “Qicai Yunnan” packaging authenticity.
  2. Evaluate appearance: authentic Dianhong features tight twist with oily luster and abundant golden tips; loose, dull or artificially colored leaf — reason for doubt.
  3. Check aroma: real Dianhong has clean sweet aroma without chemical harshness and foreign smells.
  4. Liquor should be clear, bright red, with golden ring; cloudy, brown or pale liquor indicates low quality.
  5. Taste should not be bitter or “flat” — quality Dianhong always features fullness and pronounced sweetness.

12. Interesting Facts:

• The name “Yueguang Jin Zhi” echoes another famous Yunnan tea — “Yueguang Bai” (月光白, “Moonlight white”), which represents white tea with characteristic two-colored leaf blade (silver on top, dark bottom). Both teas use poetic lunar imagery but belong to different categories: one — red, other — white.
• Fengqing, the main production area, is home to the oldest known cultivated tea tree in the world — Xiangzhuqing’s “Tea Patriarch” (锦秀茶尊, Jǐnxiù Chá Zūn) approximately 3,200 years old. Trunk circumference — 5.67 m, height — over 10 m.
• In 1958, Dianhong was designated as China’s exclusive diplomatic tea, produced only at Fengqing Tea Factory and supplied to all PRC embassies.
• During war years “one ton of Dianhong could be exchanged for 13 tons of steel” — according to export archives, currency from Yunnan red tea sales helped finance weapons purchases.
• In 2022, Dianhong production technology entered UNESCO list as part of “Traditional tea processing techniques and associated social practices in China” — world intangible heritage.

13. Comparison with Other Red Teas:

• Diānhóng Jīnyá (滇红金芽, Diānhóng Jīnyá): “Dianhong golden buds” — closest relative, made from single buds (单芽). Jinya is more delicate and sweet, with gentle aroma and light body. “Yueguang Jin Zhi,” made from one bud with leaf, has fuller taste, pronounced fruitiness and better resistance to infusions.
• Diānhóng Jīnzhēn (滇红金针, Diānhóng Jīnzhēn): “Golden needles” — finely twisted tippy cords. Visually similar to “Yueguang Jin Zhi,” but may differ in specific cultivar blend and harvest region. Profile — slightly more “dry” and less fruity.
• Qíhóng (祁门红茶, Qímén Hóngchá): Anhui red tea from small-leaf raw material. “Qimen aroma” — more perfumed, refined, with rose-orchid tones. Compared to Qihong, “Yueguang Jin Zhi” is fuller, sweeter, more oily — characteristic feature of large-leaf Dianhong. Dianhong’s resistance to infusions is significantly higher.
• Zhèngshān Xiǎozhǒng (正山小种, Zhèngshān Xiǎozhǒng): Fujian “Lapsang Souchong” — tea with smoky or “pine” aroma (in traditional version). Fundamentally different profile: if Xiaozhong is fire and smoke, then “Yueguang Jin Zhi” is honey and flowers. Raw material and terroir are completely different.
• Zūnyì Hóng (遵义红, Zūnyì Hóng): Guizhou red tea from medium- and small-leaf raw material. Compared to “Yueguang Jin Zhi,” Zunyi Hong is lighter, fresher, with pronounced acidity and less body. “Yueguang Jin Zhi” as typical Dianhong — thicker, sweeter, more oily.

In Conclusion:

Yueguang Jin Zhi is a beautiful example of how the millennial tea cradle of Yunnan continues to birth new names. Behind the poetic name “Moonlight, golden branches” stands quite tangible reality: mighty large-leaf raw material from Fengqing, passed through masters’ hands according to canons dating to the 1930s, and transformed into tea with luxurious honey-fruity aroma and velvety body. This Dianhong is good both for thoughtful gongfu brewing and unhurried morning tea drinking from a large mug — it is generous enough to remain delicious in any format. For those seeking entry into the world of Yunnan red tea, “Yueguang Jin Zhi” will be one of the most accessible yet elegant guides.
