Yín Jùn Méi银骏眉

Classification and Origin

Category: Elite red tea of the "Jun Mei" series (骏眉), second grade after Jin Jun Mei. A variety of new-type Zhèng Shān Xiǎo Zhǒng (正山小种) — without smoking.

The series includes three grades, distinguished by harvest standard: Jīn Jùn Méi (金骏眉, "Golden Eyebrows") — buds only (单芽); Yín Jùn Méi (银骏眉, "Silver Eyebrows") — one bud with one leaf (一芽一叶); Tóng Jùn Méi (铜骏眉, "Bronze Eyebrows"), also known as Chigan (赤甘) — one bud with two leaves (一芽二叶), subdivided into Xiǎo Chigan (小赤甘, leaves not opened) and Dǎ Chigan (大赤甘, leaves opened).

Coordinates: approximately 27°44′ N, 117°38′ E.

Origin: China, Fújiàn Province (福建省, Fújiàn Shěng), Nánpíng Prefecture (南平市, Nánpíng Shì), Wǔyíshān City (武夷山市, Wǔyíshān Shì), Tóngmù Village (桐木村, Tóngmù Cūn) within the Wǔyíshān National Nature Reserve (武夷山国家级自然保护区, area — 565 km²). Tongmu is the historical birthplace of all red tea, where Zheng Shan Xiao Zhong (Lapsang Souchong) was created more than 400 years ago.

Type: Red tea (black tea) (红茶, hóngchá), fully oxidized. According to European classification — black tea. Oxidation degree — 80–90%.

Facts

Yin Jun Mei appeared virtually simultaneously with Jin Jun Mei: after the successful first batch from pure buds (June 2005), masters immediately tried the "one bud — one leaf" standard, and the "gold — silver — bronze" grading system was formalized in the very first days of experiments.

Production of 500 g Yin Jun Mei requires about 50,000 "bud + leaf" shoots — slightly less than Jin Jun Mei (60,000–80,000 buds), but still a colossal amount of hand labor.

The third grade of the series — Tóng Jùn Méi (铜骏眉, "Bronze Eyebrows") — took root in the market under the name Chigan (赤甘, "Red Sweetness"), dividing into Xiao Chigan (leaves not opened) and Da Chigan (leaves opened).

The main technological difference of the entire Jun Mei series from traditional Lapsang Souchong — absence of smoking over pine wood. Only slight "touch of smoke" during withering is permitted.

Many tea masters recommend beginning acquaintance with the Jun Mei series precisely with Yin Jun Mei: it more vividly reveals the character of Tongmu terroir, is more "forgiving" to brewing errors and provides more pronounced tea "body."

History and Culture

Cultural Significance: Yin Jun Mei occupies an important niche as the "gateway" to the world of elite red teas from Tongmu. With comparable raw material quality and technology, it is notably more accessible than Jin Jun Mei, making it a popular choice for daily tea drinking among connoisseurs and for introduction to the Jun Mei series. In China's domestic market, Yin Jun Mei is one of the most sought-after red teas in the middle and upper price segments.

History: Yin Jun Mei appeared simultaneously with Jin Jun Mei in 2005, when a team of masters led by Jiāng Yuánxūn (江元勋) and Liàng Jùndé (梁骏德) developed the grading system for the Jun Mei series. According to participants' accounts, after the successful first batch of tea from pure buds, the masters tried making tea from "one bud — one leaf," and it was then that the three-level "gold — silver — bronze" classification by harvest standard was formalized. The production technology and commercialization of Yin Jun Mei proceeded parallel to Jin Jun Mei: stabilization in 2006 with participation of tea patriarchs Zhāng Tiānfú (张天福) and Luó Shaojun (骆少君), market entry in 2008.

Botany and Raw Material

Cultivar: Local wild or semi-wild population of small-leaf tea bush — Qízhǒng (奇种, Qízhǒng) / Càichá (菜茶, Càichá), Camellia sinensis var. sinensis. Heterogeneous seed population that has grown in the highlands of Wuyishan Reserve for centuries. Small-leaf forms are distinguished by higher amino acid content and lower polyphenol and caffeine content (compared to var. assamica), ensuring signature sweetness and absence of harsh bitterness.

Picking: Usually begins after Qīngmíng (清明, ~April 5) and continues until Gǔyǔ (谷雨, ~April 20) and slightly later — Yin Jun Mei harvest typically begins a few days later than Jin Jun Mei, as it's necessary to wait for the first leaf to open. Harvest is conducted exclusively by hand, in dry weather.

Pluck Standard: One bud with one tender, barely opened upper leaf (一芽一叶, yī yá yī yè). This is the key difference from Jin Jun Mei (buds only) and Tong Jun Mei (one bud with two leaves). About 50,000 buds with leaves are required for 500 g of finished tea.

Raw Material: Buds and leaves must be whole, undamaged, uniform in size. The leaf — tender, not coarse, without darkening. Minimal delay between harvest and processing start.

Terroir

Altitude: 1000–1800 m above sea level. Optimal zone — 1200–1500 m. Forest cover constitutes 96.3%.

Climate: Subtropical mountain monsoon. Average annual temperature ~11–18°C. Precipitation — 2000–2300 mm/year. Humidity — ~80%. Fog — more than 120 days per year. Significant daily temperature variation promotes accumulation of amino acids and aromatic compounds in the leaf.

Soil: Mountain red and mountain-yellow soils, slightly acidic (pH 4.5–5.0), rich in organic matter, with high iron and manganese content. Soil layer depth — 30–90 cm. Well-drained.

National Nature Reserve with an area of 565 km², UNESCO World Heritage Site (1999). Mountains of red sandstone and volcanic rocks; steep gorges, waterfalls, subtropical forests with exceptional biodiversity.

Located deep within the reserve. Tea trees grow under forest canopy, in semi-wild and wild state, on steep mountain slopes.

Production

Hand-picking of one bud with one tender leaf. Work on steep mountain slopes, access to tea trees is difficult.

Harvested material is spread in thin layers on bamboo trays in ventilated rooms. Temperature and humidity control is applied (温湿调控). The master alternates natural and warm withering, achieving ~60–65% moisture loss. Duration — 8–14 hours. During withering, slight exposure to light smoke is permitted — unlike traditional Zheng Shan Xiao Zhong, where smoking is intensive, in Jun Mei it is minimal or absent.

Manual, delicate. The presence of leaf provides slightly more cell juice, facilitating subsequent oxidation compared to pure-bud Jin Jun Mei. Rolling — not coarse, preserves integrity of bud and leaf. Finished tea is not sifted (不过筛, bù guò shāi) to preserve shape.

At controlled temperature (~20–25°C in room, ~30°C in leaf mass) and humidity (~90–95%). Key stage for forming honey-fruity aroma. Master determines readiness by color (transition to copper-red) and aroma (appearance of characteristic "honey sweetness"). Insufficient oxidation gives bitterness, excessive oxidation deprives tea of signature "honey" note, bringing profile closer to ordinary Zheng Shan Xiao Zhong.

Traditional drying in bamboo baskets over acacia charcoal (槐炭). Two-stage process: Máohuǒ (毛火) at ~110°C and Zúhuǒ (足火) at ~130°C. Precise control of time and temperature is critical for forming honey note. Residual moisture — 3–4%.

Manual final culling — removal of broken fragments, foreign inclusions.

Organoleptic Profile

Dry Leaf Appearance: Thin, dense, slightly curved shoots — bud with one tender leaf. Authenticity conditions: silvery-gray or silvery-black coloration (银灰色) — highest grade; golden-red tint — acceptable but lower class. Down on bud — silvery (hence the name). Leaves darker than bud. Conditions — whole, without broken fragments, uniform. Tight rolling, "eyebrow-like" shape.

Dry Leaf Aroma: Clean, sweet, with honey, floral (rose, orchid) and fruity (longan, lychee) notes. Light malty and caramel overtones. More complex and "voluminous" than Jin Jun Mei due to leaf contribution.

Liquor Aroma: Complex: floral-fruity background (flowers, longan, dried fruits), honey sweetness, subtle sweet potato notes (薯香, shǔ xiāng) — characteristic "high-mountain character" (高山韵, gāoshān yùn). Aroma is persistent, lasting through 8th and more infusions.

Liquor Color: Golden-amber, clear, transparent. Best batches — orange-golden. Highest standard — orange-yellow (橙黄), transparent; reddish, cloudy or dark liquor — sign of reduced quality.

Spent Leaves: Whole, elastic buds with one unfolded leaf. Color — antique copper (古铜色, gǔtóng sè) for highest grade; red-brown — for second. Leaves glossy, "alive."

Taste: Soft, smooth, with slightly more pronounced structure and "body" than Jin Jun Mei. Sweetness dominates, but light, pleasant astringency is present, adding depth. Honey, fruity (longan, lychee, peach), malty notes. Pronounced "returning sweetness" (回甘, huígān). Long-lasting, clean aftertaste with honey-fruity tint and cooling sensation in throat (喉韵, hóuyùn). Good brewing endurance.

Chemical Composition

Alkaloids: Caffeine — 3–5% dry weight. Content per cup ~20–60 mg. Also theobromine and theophylline.

Amino Acids: 1.5–3.5% dry weight. L-theanine — main component, responsible for sweetness, softness and relaxing effect. Content somewhat lower than in pure-bud Jin Jun Mei, manifesting in slightly more pronounced astringency.

~0.02%. Linalool, geraniol, phenylacetaldehyde and other components forming the floral-honey-fruity profile.

Soluble sugars — 2–4%, pectin — 1–2%, organic acids — ~1%.

Minerals: ~30 elements. Main ones: potassium, phosphorus, calcium, magnesium, iron, manganese, fluorine. Trace elements: zinc, copper, selenium.

Polyphenols: 10–20% dry weight. With full oxidation, catechins transform into theaflavins (茶黄素, 0.4–2%) and thearubigins (茶红素, 5–11%), forming liquor color and taste "velvetiness."

Vitamins: C, B₁, B₂, B₃, E, K.

Health Notes

Synergy of caffeine and L-theanine provides steady tone without anxiety — effect of "calm alertness."

Theaflavins and thearubigins actively neutralize free radicals. According to some data, red tea's antioxidant potential is comparable to green tea, though antioxidant profiles differ.

Polyphenolic compounds promote vessel elasticity, may affect LDL cholesterol levels. Theaflavins dilate capillaries.

Fully oxidized red tea gently affects gastric mucosa, especially suitable after meals.

Tea polyphenols and tannins suppress pathogenic bacteria growth, support oral health.

"Warm" nature according to TCM canons, ideal for cold seasons and people with "cold" constitution.

L-theanine stimulates α-brain wave generation, promoting relaxed concentration.

Brewing

Tea Amount: 4–5 g per 100–120 ml (gongfu method); 2–3 g per 200–250 ml (European method).

Teaware: Porcelain gàiwǎn (盖碗) 100–120 ml — ideal option: doesn't absorb aroma, allows precise infusion control. Glass teaware allows observing bud opening. Yíxīng teapot (宜兴紫砂壶) is also appropriate. Fairness cup (公道杯) is mandatory.

Water Temperature: 90–95°C. Full boiling water can be used to reveal full aromatic spectrum; for delicate batches — 85–90°C.

Storage

Container: Airtight, opaque — tin can, foil bag with zip closure, ceramic vessel.

Shelf Life: Optimal — 12–18 months. Quality batches retain properties up to 2 years, but fresh tea is preferable.

Dry, cool, dark place, away from foreign odors. Temperature 10–25°C, humidity not above 60%.

Refrigerator storage is not necessary and not recommended without reliable airtight packaging. Red tea stores well at room temperature.

Comparison

"Elder brother" — from buds only. More refined, sweet, "airy," without slightest astringency. Liquor color more saturated (orange-amber). Price significantly higher. Yin Jun Mei by contrast — slightly more structured, with light astringency and greater "body."

"Younger brother" — one bud with two leaves. Denser, with noticeable astringency, darker liquor color. Aroma — with pronounced caramel-fruity notes. Most accessible in the series.

"Ancestor" of entire series. Produced from more mature leaf, traditionally smoked over pine wood. Taste denser, with characteristic "smoky" note (in smoked versions) or caramel-malty (in unsmoked). Yin Jun Mei — significantly more delicate and "clean" in profile.

Yunnan red tea from large-leaf cultivar buds (var. assamica). Denser, more saturated, with chocolate-spicy profile. Yin Jun Mei — finer, lighter, with accent on floral-honey elegance.

Price and Authenticity

~50,000 shoots per 500 g dry tea, hand-picking.

Authentic raw material — only from Tongmu protected zone.

All key stages — by hand.

2–3 weeks per year.

Specialized shops with confirmed origin; ideally — directly from producer (正山堂, 骏德茶厂).

Buds with silvery down, one tender leaf. Silvery-gray coloration — highest grade. Leaves — not coarse, without stems.

Clean honey, floral-fruity, without chemical harshness, mustiness or pronounced smoke.

Golden-amber, transparent. Cloudy or dark red — sign of substitution or low quality.

Yin Jun Mei for 100–200 yuan/500 g is almost certainly produced from raw material from other regions.
