Qiāndǎo yù yè · new.thetea.app

Qiandao Yu Ye is a young but already distinguished green tea from Zhejiang Province, born on the shores of the famous Thousand Island Lake (千岛湖, Qiāndǎo Hú). Created in 1982 based on Xi Hu Longjing technologies using the local Jiukeng cultivar, it quickly gained recognition: receiving its name from the legendary Professor Zhuang Wanfang and by 2007 becoming a product with protected geographical indication. The unique “lake-island” microclimate, acidic forest soils, and pristine waters of a first-class water body shape the tea’s character—a rich bean-nutty aroma, dense fresh taste, and long sweet aftertaste.

1. Classification and Origin:

Type: Green tea (unfermented), chaoqing (炒青, chǎoqīng) — dried by pan-firing in a wok. Subtype — bianxing (扁形, biǎnxíng) — flat form.
Category: Modern famous teas of China (新创名茶, xīnchuàng míngchá); regional green teas of Zhejiang Province.
Origin: China, Zhèjiāng Province (浙江, Zhèjiāng), Chun’an County (淳安县, Chún’ān Xiàn), Qiandaohu Lake area (千岛湖, Qiāndǎo Hú). Production core — Qīngxī district (青溪, Qīngxī) and adjacent mountain ranges with island microclimate.
Geographic coordinates: Approximately 29°36′ North latitude, 118°54′ East longitude.

2. History and Cultural Significance:

History: Qiandao Yu Ye is one of the most successful “new famous teas” of China from the second half of the 20th century. Its history begins in 1982, when the tea-forestry enterprise at Qiandaohu Lake (千岛湖林场, Qiāndǎo Hú Línchǎng) developed a new tea using the local Jiūkēng variety (鸠坑, Jiūkēng) and adapted Xi Hu Longjing technology. Initially the tea was called “Longjing from Thousand Island Lake” (千岛湖龙井, Qiāndǎo Hú Lóngjǐng). In July 1983, the famous tea scientist, Professor Zhuāng Wǎnfāng (庄晚芳, Zhuāng Wǎnfāng) of Zhejiang Agricultural University, visited Chun’an to inspect tea production. Evaluating the robust, downy buds and unique landscapes of the Thousand Islands, he personally inscribed the new name — “Qiandao Yu Ye” (千岛玉叶, “Jade Leaf of the Thousand Islands”), thereby establishing the tea’s individual identity, distinct from West Lake Longjing.

Further recognition came rapidly: in January 1986 the tea passed official certification, in 1987 the trademark was registered. In 1986 Qiandao Yu Ye was awarded the Second Prize of Zhejiang for Scientific and Technological Progress. In 1988 and 1989 it received the title “first-class famous tea of the province” from the Zhejiang Department of Agriculture for two consecutive years. In 1991 it was issued the certificate “Famous Tea of Zhejiang Province.” The culmination came in 2007, when Qiāndǎo Yǔ Yè received the status of a product with national geographical indication (国家地理标志保护产品), finally establishing Qiandaohu Lake as a key tea region of Zhejiang.
Name: “Qiandao” (千岛) — “thousand islands,” a direct reference to Qiandaohu Lake, an artificial reservoir formed after construction of the Xin’anjiang Hydroelectric Station. On its waters are scattered more than a thousand islands, creating an incomparable landscape. “Yu” (玉, yù) — “jade, nephrite,” symbolizes the tea’s value, purity and nobility. “Ye” (叶, yè) — “leaf.” Thus, the full name poetically conveys the image of precious tea leaves born among a thousand islands. The name was given by Professor Zhuang Wanfang, who emphasized that the white down on the robust buds makes the tea unlike classic Longjing and deserves its own identity.
Cultural significance: Qiandao Yu Ye became the calling card of Chun’an County and Qiandaohu Lake — one of the largest tourist centers in Eastern China. The tea is inseparably linked with the ecological reputation of the lake: Qiandaohu is a national first-class water body with transparency up to 7 meters, one of the cleanest freshwater lakes in the country. The region has long been known as “Muzhou” (睦州, Mùzhōu) — a historical name that appears in poems dedicated to local teas: “Born on the shores of the Thousand Islands — quality surpasses all. Yu Ye and Yu Ya — sister teas from Muzhou.” The lake territory is among the first 44 national scenic zones of China and in the top ten national forest parks. For modern Chun’an, Qiandao Yu Ye is not only the economic foundation of the tea industry, but also a cultural brand uniting tea and tourism.

3. Botanical Description and Raw Material:

Variety / Cultivar: Main cultivar — Jiūkēng quntichong (鸠坑群体种, Jiūkēng qúntǐ zhǒng), a provincial-level seed variety. This is a historically formed population of Camellia sinensis var. sinensis, characterized by large, fleshy leaves with abundant down. Tea polyphenol content — more than 30%, ensuring pronounced flavor depth. The cultivar possesses high adaptability and universal suitability for various processing types. Additionally used is cultivar Longjing 43 (龙井43, Lóngjǐng 43) — to improve quality of early spring harvest due to earlier vegetation periods.
Picking: Main picking — early spring. Timing varies: Longjing 43 gives first harvest approximately from March 20, Jiukeng — from late March. Quality peak — period from Qīngmíng (清明) to Gǔyǔ (谷雨). After Gǔyǔ the leaf is used for everyday tea (炒青, chaoqing).
Picking standard: For special grade (teji) — bud with one unopened leaf (一芽一叶初展, yī yá yī yè chū zhǎn), with the bud being longer than the leaf. 500 g of fresh leaf contains 4100–4300 buds. For first grade — bud with one leaf, slight non-uniformity permitted. For second grade — small proportion of “bud + two leaves” material allowed. General requirements: damaged, purple, excessively thin or overripe shoots not permitted; material must be uniform, clean, with pronounced down.
Raw material requirements: Fresh leaf after picking undergoes mandatory spreading (摊放, tānfàng) for 6–12 hours, until moisture drops to 70–72%. This stage is critically important for aroma formation and leaf preparation for pan-firing.

4. Terroir and Cultivation Features:

Climate and topography: The Qiandaohu area belongs to the subtropical monsoon climate zone. Average annual temperature — 15–17 °C, frost-free period — 230–270 days, annual precipitation — 1319.7 mm. Main rainy periods — spring rains and “plum rain” season (meiyu). July-August — dry period (伏旱, fúhàn). Chun’an County topography — predominantly hilly, with elevation differences: periphery elevated, central part — lowland, occupied by the lake. Key terroir feature — “lake-land microclimate” (湖陆小气候, hú lù xiǎo qìhòu): the huge mass of fresh water moderates temperature fluctuations, forms abundant morning mists and stable humidity, optimal for tea bushes.
Growing elevation: Tea gardens located on hilly slopes around the lake at 200–600 m elevation. Quality production core — Qingxi district, where primeval forests create natural shading.
Soils: Acidic red soils (红壤, hóng rǎng) and sandy soils (砂质土), rich in minerals. Reaction — weakly acidic, optimal for Camellia sinensis.
Ecology: Forest cover of Qiandaohu territory — from 81% to 93%. The lake has national first-class water body status (国家一级水体) with transparency up to 7 meters. Such ecological purity of the surrounding environment directly influences tea raw material quality.

5. Production Technology:

Qiandao Yu Ye technology traces back to Xi Hu Longjing methods, but adapted for the characteristics of the local Jiukeng cultivar with its large, downy buds. The entire process takes place in a flat wok; the finished tea must meet the “four qualities” standard: brightness, flatness, evenness, straightness (光、扁、平、直, guāng, biǎn, píng, zhí). Mass loss in the process — 60–65%, final moisture — no more than 6%.

Fresh leaf picking (鲜叶采摘, xiānyè cǎizhāi): Hand picking according to the standard described above. Full compliance with criteria of “tenderness, uniformity, cleanliness” (嫩、匀、净, nèn, yún, jìng) required.
Spreading (摊放, tānfàng): Picked leaf is spread on bamboo trays in shaded, ventilated places for 6–12 hours. During the process moisture decreases from ~78% to 70–72%, partial protein breakdown occurs and volatile aromatic compounds are released.
Fixation and shaping (杀青做形, shāqīng zuòxíng): Conducted in a flat wok. For highest grade — 110–120 °C, for medium — 120–130 °C. Leaf is loaded in portions of 150 g (highest grade) or 200 g (medium). The master uses alternating hand techniques: “shaking” (抖, dǒu), “leading” (带, dài), “pressing” (捺, nà), “grasping” (抓, zhuā), “laying” (搭, dā). The task — stop enzymatic oxidation, evenly soften the leaf, remove grassy smell and give initial flat form. Readiness is determined by leaf darkening and its ability to be shaped. The shaped semi-finished product is laid out for cooling and moisture redistribution (摊凉回潮, tānliáng huícháo).
Sifting and spreading (筛分摊凉, shāifēn tānliáng): Intermediate separation by size and removal of fragments.
Final firing and form setting (煇锅定型, huì guō dìngxíng): Conducted at 70–80 °C. Main techniques — “shaking” (擞, sǒu), “straightening” (挺, tǐng), “pressing” (压, yā), “polishing” (磨, mó). At this stage the rule “hand does not leave tea, tea does not leave wok” (手不离茶，茶不离锅) applies. Pressure control is critically important: excessive force breaks the leaf, weak — does not give needed flatness; overheating yellows the tea, underheating makes the color dark. Result — smooth, flat, straight tea leaves with silky luster.
Final sifting and sorting (筛分整理, shāifēn zhěnglǐ): Dry tea is sifted to even the fraction, remove fragments and dust. Separation into grades by size, integrity, amount of down and color.

6. Organoleptic Characteristics:

Dry leaf appearance: Flat, straight, slightly flattened form (扁平挺直). Color — green with tender yellow tint (翠绿嫩黄), with visible white down on the surface. Buds large, dense. Tea leaves smooth, uniform, without fragments. Externally resembles Xi Hu Longjing, but differs in more pronounced down and slightly greater leaf mass.
Dry leaf aroma: Clean, high, with pronounced bean note (豆香, dòu xiāng) — main tone — and soft undertone of fresh greenery (清香, qīng xiāng). Light “milky” tenderness (嫩香, nèn xiāng) present, characteristic of young raw material.
Liquor aroma: Fresh, persistent, with dominating bean-nutty profile. As the cup cools, floral and herbal undertones emerge. Aroma clean, without foreign admixtures.
Taste: Rich and full-bodied (醇厚, chúnhòu) — noticeably denser than classic Xi Hu Longjing. Freshness (鲜爽, xiānshuǎng) clearly expressed, due to high amino acid content in Jiukeng cultivar. Distinct returning sweet aftertaste (回甘明显, huígān míngxiǎn). Without bitterness and sharp astringency when properly brewed. With prolonged steeping moderate astringency may appear.
Liquor color: Yellow-green, bright, clear (黄绿明亮). Fresh tea — with tender greenish glow; with storage the liquor darkens.
Spent leaves (wet leaves): Tender green, fleshy, uniform leaflets, gathered in neat “bouquets” (嫩绿成朵, nèn lǜ chéng duǒ). Leaves elastic, dense. Even coloring without spots and darkening — sign of quality processing.

7. Chemical Composition:

The tea is distinguished by high polyphenol content (>30% — characteristic feature of Jiukeng cultivar), as well as rich amino acid profile.

Polyphenols (catechins): More than 30% of dry mass — above average for green teas. Main components — EGCG, ECG, EGC. Provide antioxidant activity, structural taste density and astringent component, balanced by amino acids.
Amino acids: High content (exact figures for Qiandao Yu Ye not standardized, but source material Jiukeng is characterized by good amino acid accumulation). L-theanine — main component, forming sweetness and umami-like “body.”
Alkaloids: Caffeine — moderate content, providing mild tonic effect in synergy with L-theanine. Also present are theobromine and theophylline.
Vitamins: Vitamin C — relatively high content in fresh raw material. B-group vitamins. Vitamin K.
Minerals: Fluorine — 200–300 ppm (tooth enamel strengthening). Potassium, manganese, zinc. Acidic red soils with rich mineral composition provide saturated elemental profile.
Flavonoids: Additional antioxidant compounds, including vitexin, morin and catechins. Pronounced antibacterial activity noted.

8. Health Properties:

Antibacterial action: Tea polyphenols possess pronounced bactericidal activity — suppression of dysentery bacillus growth, by estimates, exceeds 90%.
Antioxidant protection: High catechin content (>30% polyphenols) neutralizes free radicals, supporting cellular health.
Tooth enamel strengthening: Fluorine content 200–300 ppm promotes formation of protective layer on enamel, and antibacterial action of polyphenols suppresses cariogenic microorganisms.
Metabolism and healthy weight support: Caffeine together with polyphenols stimulates fat breakdown and thermogenesis.
Mild tonic effect: L-theanine and caffeine create state of calm alertness, improving cognitive functions without anxiety.
Cardiovascular system support: Catechins promote reduction of LDL cholesterol levels, maintenance of vascular elasticity.
Digestive support: Polyphenols and tannins stimulate digestive enzyme secretion, ease digestion of fatty and heavy food.

9. Brewing:

Water temperature: 80–85 °C. Absolutely not recommended to pour boiling water — this destroys chlorophyll (liquor yellows) and increases bitterness.
Tea amount: 3 g per 150 ml (1:50 ratio). For more concentrated taste — 5 g per 150 ml.
Teaware: Glass tumbler (recommended — allows observing leaf opening and liquor clarity); white porcelain gaiwan (盖碗); porcelain cup with lid.
Process:
1. Warm teaware with hot water, drain.
2. Add tea. Use bottom loading method (下投法) — tea to bottom, then water.
3. Rinsing not obligatory for tender green tea. If desired — quick rinse (1–2 seconds).
4. First infusion — directed stream (定点注水, dìngdiǎn zhùshuǐ), steep 10 seconds. Drain or begin drinking.
5. Subsequent 2–5 infusions — increase time by 5–10 seconds. Quality Qiandao Yu Ye withstands 5 brewings.
6. Liquor recommended to drink immediately after pouring — prolonged steeping (more than 3 minutes) increases astringent component.

10. Storage:

Like all delicate green teas, Qiandao Yu Ye is sensitive to light, heat, moisture and foreign odors. Optimal storage conditions: airtight packaging (vacuum bag, tightly closed tin), temperature 0–5 °C. When removing from refrigerator — hold in closed packaging until room temperature (1–2 hours) to avoid condensation. Storage period in airtight packaging at proper temperature — up to 12 months. After opening — preferably consume within 3–4 weeks. Traditional method: tea is placed in paper bags, which are slightly compacted and tied, then placed in clay or porcelain containers with tightly closed lids.

11. Price and Counterfeits:

Qiandao Yu Ye is a tea with protected geographical indication (since 2007), which supports its price level and reputation. Cost varies in wide range: pre-Qingming raw material of teji class — most expensive; tea from Qingming–Guyu period — optimal quality-price ratio; post-Guyu raw material — budget option for daily consumption.

How to avoid counterfeits:

Appearance: Authentic Qiandao Yu Ye — flat, straight, with pronounced white down and tender yellow-green color. Counterfeits (often from lower quality raw material from other regions) look duller, with non-uniform color and broken fragments.
Aroma: Clean bean/nutty aroma without mustiness and raw grassiness. Absence of characteristic bean note — sign of substitution.
Liquor: Should be bright yellow-green, clear. Cloudy or dark liquor indicates poor quality raw material or technology violation.
Taste: Full-bodied, fresh, with pronounced returning sweetness (huigan). Flat, watery taste without aftertaste — sign of counterfeit.
Source: Purchase tea with geographical indication marking “千岛玉叶” from certified Chun’an producers. Pay attention to harvest date and transparency of origin information.

12. Interesting Facts:

The tea was named by Professor Zhuang Wanfang (1908–1999) — one of the “four pillars” of Chinese tea science in the 20th century, author of fundamental works on taxonomy and tea history. His calligraphic inscription “千岛玉叶” is preserved as a relic of Chun’an tea culture.
Thousand Island Lake (千岛湖) — the largest artificial freshwater reservoir in Eastern China, formed in 1959 after construction of the hydroelectric station on Xin’anjiang River (新安江). On its waters are counted 1078 islands with area more than 0.25 hectares each. This unique water space creates the microclimate that forms the tea’s character.
Xin’anjiang River, feeding the lake, was sung by Li Bai: “I ask about Xin’anjiang — is it clear to the bottom?” The purity of these waters is not only a poetic image, but a real ecological standard: the lake maintains first-class water body status with transparency up to 7 meters.
Qiāndǎo Yù Yè and Qīngxī Yù Yá (清溪玉芽, Qīngxī Yù Yá) — “sister teas from Muzhou”: both produced in the same region by similar technology, but from different raw material standards. The poetic couplet states: “Born at the shores of the Thousand Islands — quality surpasses all. Yu Ye and Yu Ya — sister teas from Muzhou.”
Chun’an County — largest by area in Zhejiang Province. Its historical name — Mùzhōu (睦州) — dates to the Sui era and literally means “Land of Harmony.”

13. Comparison with Other Zhejiang Green Teas:

Xī Hú Lóngjǐng (西湖龙井, Xīhú Lóngjǐng): Main “relative” and source of inspiration for Qiandao Yu Ye technology. Differences are substantial: Longjing uses Longjing 43 cultivar or Qun Tizhong Longjing (without abundant down), its aroma — higher, “chestnut-bean,” form — perfectly flat, smooth, practically without down. Qiandao Yu Ye, thanks to Jiukeng cultivar, is more downy, more massive in bud structure, with denser and fuller taste.
Ānjí Bái Chá (安吉白茶, Ānjí Bái Chá): Green tea from northern Zhejiang (Anji County). Produced from albino cultivar Bai Ye Yihao with record amino acid content (~6–7%). Externally — thin, elongated, light green with yellow. Taste — exceptionally fresh, with pronounced umami and minimal astringency. Qiandao Yu Ye, in contrast, possesses greater body fullness and bean-nutty profile.
Jīnhuá Jǔyán (金华举岩, Jīnhuá Jǔyán): Historical green tea from Jinhua city, dating to Tang era. Form — slightly twisted, aroma — floral-fruity. Unlike flat Qiandao Yu Ye, Juyan is more voluminous in form and tenderer in taste.
Kāihuà Lóng Dǐng (开化龙顶, Kāihuà Lóng Dǐng): Produced in Kaihua County in western Zhejiang. Form — straight, thin, resembling needle. Aroma — clean floral-chestnut, taste — light, fresh. Qiandao Yu Ye differs in flat form and more saturated, dense taste.

In conclusion:

Qiandao Yu Ye is a tea young by Chinese tea history standards, but its rapid path from nameless “lake longjing” to product with national geographical indication speaks to impeccable terroir and mastery of Zhejiang tea makers. Behind each flat, downy tea leaf stands a unique ecosystem — the purest lake among a thousand islands, acidic forest soils, monsoon mists. Bean-nutty aroma, full-bodied, fresh taste with extended returning sweetness (huigan) and fleshy, elastic buds in the spent leaves — all this makes Qiandao Yu Ye a worthy alternative for those who value Longjing style but seek a more saturated, “lake” interpretation.
