Tóngbǎi yù yè

Tongbai Yu Ye is the signature tea of Tongbai County in Henan Province, a flat (扁形) green tea technologically and aesthetically related to Xi Hu Longjing. The name translates as “Jade Leaf of Tongbai,” and this is no exaggeration: the smooth, flat, emerald-oily leaf, apricot-green transparent liquor, long-lasting persistent aroma, and expressive sweetness make this tea one of the finest green teas of the “Central Plain” (中原). It is protected by national geographical indication (农产品地理标志) and has its own industry standard GH/T 1445-2023.

1. Classification and Origin:

• Type: Green tea (unoxidized), subcategory — flat (扁形) green tea, processed by wok fixation (炒青).
• Category: Regional famous tea with protected origin — national geographical indication product (国家地理标志产品). One of the “Ten Famous Teas of Henan Province” (河南十大名茶). Included in the list of “National Famous New Agricultural Products” by China’s Ministry of Agriculture. Since 2022, the “Tongbai Yu Ye” brand is among the “Top 100 Strongest Public Tea Brands in China” (全国茶叶百强公用品牌).
• Origin: China, Hénán Province (河南, Hénán), Nányáng Prefecture (南阳, Nányáng), Tóngbǎi County (桐柏县, Tóngbǎi Xiàn). The production core is the eastern slope of the main peak of the Tongbaishan Range — Taibai Peak (太白顶, Tàibái Dǐng, 1140 m), the area around Jintaiguan Temple (金台观), Shuiliandong Waterfall (水帘洞), and Peach Blossom Cave Taohuadong (桃花洞).
• Geographic coordinates: Approximately 32.37° N, 113.42° E.

2. History and Cultural Significance:

• History: Tongbai is one of the most ancient tea-growing regions of central China. According to the “Shen Nong Ben Cao” (《神农本草》), Shěn Nóng (神农), the mythical patron of agriculture, “tasted a hundred herbs, encountered seventy-two poisons in a day, and was healed by tea” — and local legends relate Shen Nong’s activities specifically to the Tongbaishan Mountains. The tea saint Lù Yǔ (陆羽) in the “Classic of Tea” (《茶经》) mentioned tea from the ancient Yìyáng Commandery (义阳郡, Yìyáng Jùn), which included the area of modern Tongbai, giving it high praise. A folk saying states: “Ask where Master Lu is going? — He drinks tea only on Taibai Peak” (借问陆君何处去？品茗只向太白峰). During the Tāng dynasty (唐, 618–907), the area was already a renowned tea zone. During the Sōng (宋, 960–1279), Tongbaishan was one of thirteen state tea markets (茶场). A Song scholar, visiting Taibai, left a famous couplet inscription: “Three floors of pavilion — for reading and discussing the world; Nine mountain streams — to listen to waterfalls and brew tea” (阁楼三层读书论世，泉飞九壑听瀑烹茗).

  The modern tea “Tongbai Yu Ye” was created in 1985 at the Tóngbǎi Tea Breeding Station (桐柏茶种场) — initially under the name “Shuilian Yu Ye” (水帘玉叶, “Jade Leaf of Water Curtain”), after the waterfall. In the same year, the novelty won at a tasting competition in Nanyang and received a prize at the provincial exhibition. In 1986, it was awarded the title “Premium Quality Tea of Henan Province.” In 1988, professors from the Tea Science Faculty of Zhejiang Agricultural University (now Zhejiang University) confirmed the highest quality level. In 1997 and 1999 — the title “Famous Tea of Henan”; in 1999 — bronze medal at the Kunming World Horticultural Exposition. In 2001 — status as a “famous product” at China’s International Agricultural Exhibition. In 2002 — inclusion in the “Top Ten Famous Teas of Henan.” In 2006 — silver medal at the VI International Famous Tea Competition. In 2015 (December) — registration by China’s Ministry of Agriculture as a national geographical indication product. In 2023, industry standard GH/T 1445-2023 “Tongbai Yu Ye Cha” (桐柏玉叶茶) was approved.

• Name: “Tongbai” (桐柏) — the name of the county and mountain range, literally “Tung tree on cypress” (historical toponymy). “Yu” (玉) — jade, nephrite, symbol of purity and nobility. “Ye” (叶) — leaf. Full meaning: “Jade Leaf of Tongbai” — a poetic metaphor emphasizing the emerald color, smoothness, and value of the tea leaf.

• Cultural significance: Tongbai is the “Tea Homeland of the Central Plain” (中原茶乡), one of ten key tea-producing counties in Henan. Tea culture is deeply woven into daily life: a guest who is not offered tea feels unwelcome, and the host feels discourteous. A local saying: “When a guest comes on a frosty night — tea replaces wine” (寒夜客来茶当酒). Since 2016, the annual “Spring First Picking” (春茶第一采) is held, as well as a hand-made Tongbai Yu Ye competition — a festival that attracts masters from throughout the county. Tongbai’s tea industry provides employment for more than 50,000 people.

3. Botanical Description and Raw Material:

• Species: Camellia sinensis var. sinensis.
• Variety / Cultivar: Local small-leaf population planting (小叶种群体种). On Tongbaishan Mountain, extensive massifs of wild and feral small-leaf tea trees (野生茶树) are preserved — some specimens reach a century in age. This is China’s largest massif of wild small-leaf tea trees with organic certification. Since 1962, the Tóngbǎi Tea Breeding Station (桐柏茶种场) has operated — Henan’s only specialized tea variety breeding station, providing annual output of more than 10 million seedlings.
• Picking: Spring (late March — April); premium batches — before the Qīngmíng festival (清明前). For the “Tongbai Yu Ye” line, exclusively spring raw material is used.
• Picking standard: Highest grade — single bud or bud with one leaf at initial opening stage (一芽一叶初展), with at least 80% of buds being longer than the leaf. Medium grade — bud with two leaves at initial opening stage (一芽二叶初展).
• Raw material requirements: Damaged, diseased, purple leaves, single plates, fish-shaped leaves (鱼叶), and scales are not permitted. Shoot length must be uniform. Raw material is transported in bamboo baskets (polyethylene bags are strictly prohibited).

4. Terroir and Cultivation:

Tongbai County is located on the border of Henan and Hubei, in the heart of the Tongbaishan Range (桐柏山) — the eastern extension of the Qinling-Huaihe system, which is China’s main climatic watershed between the Yangtze River basin (subtropics) and Yellow River basin (temperate zone). Tóngbǎi stands at the source of the Huaihe River (淮河) — eastern China’s third longest river.

• Growing altitude: 400–800 m (main plantations); individual wild massifs — up to 1000 m. Main peak Taibai — 1140 m.
• Climate: Transitional subtropical-temperate, monsoon. Average annual temperature ~15°C. Precipitation ~1168 mm/year, distributed mainly in spring-summer. Abundant warm moisture and frequent mountain fogs create ideal “soft light” for tea bushes.
• Soils: Mountain yellow-brown (黄棕壤) and mountain brown soils, acidic and weakly acidic (pH 4.5–6.0), with high organic content. Parent rock — granites and gneisses. Soils are well-drained and enriched with minerals.
• Agrotechnics: Tongbai is a zone with minimal industrial impact, located 80 km from the nearest major city. Air, soil, and water quality meets criteria for ecologically clean agriculture. 100% of tea plantations are certified as safe (无公害). In 2023, two county farms were among the first in the country to receive “ecological low-carbon tea producer” status.

5. Production Technology:

The Tóngbǎi Yǔ Yè technology is classic for flat green teas (扁形绿茶), close to Longjing style but adapted to local raw material. The key feature is the “huiguo” (辉锅) stage, on which the flatness, smoothness, and luster of the final leaf depend. Full cycle: picking → spreading → wok fixation → pause for moisture redistribution → sifting → huiguo (final shaping-drying) → packaging.

• Picking (采摘 — cǎizhāi): Hand picking according to the standard described above. Raw material is immediately delivered to the factory.
• Spreading (摊放 — tānfàng): Raw material is spread in shade, 2–3 cm thick, for 5–12 hours with two turnings. Moisture decreases by 25–30%, leaves become soft and elastic, a light clean aroma appears.
• Kill-green (杀青 — shāqīng): The wok is heated to 100–110°C, pre-oiled with tea oil. Load — ~150 g. Leaves make a light crackling sound when hitting the wok. Hand technique passes through three phases: (1) “dou” (抖, “shaking”) — 1–2 min, 40–45 movements per minute, light hand, quickly; (2) “dou + dai + shuai” (抖 + 带 + 甩, “shaking + leading + throwing”) — 2–3 min, pressure increases, leaves begin to flatten; (3) “na + zhua” (捺 + 抓, “pressing + grasping”) — 8–9 min, leaves are brought to ~80% dryness and acquire flat form. Unloading from wok.
• Moisture redistribution (回潮 — huícháo): Hot leaves are thinly spread on bamboo tray, cooled, covered with damp cloth for 30–40 minutes. Leaves “return” internal moisture, become soft, which is critically important for the next stage.
• Sifting (过筛 — guòshāi): Leaves are passed through bamboo sieve (3.5 meshes per inch). Large and small fractions are processed separately in huiguo.
• Huiguo — final shaping and drying (辉锅 — huīguō): Decisive stage determining flatness, smoothness, luster, and final flavor-aromatic profile. Wok temperature 70–80°C (for highest grades — lower, for medium — higher), toward process end — 50–60°C. Load: 250–300 g (3–4 portions after fixation). Highest grade is processed ~20 minutes, medium — longer. Leaves are smoothly pressed against wok wall, acquiring final flat, smooth, lustrous form.
• Packaging and storage (包装贮藏 — bāozhuāng chǔcáng): Cooled tea is packaged in airtight containers to preserve freshness.

6. Organoleptic Characteristics:

• Dry leaf appearance: Flat (扁平), smooth (光滑), even. Bud down is hidden within leaf structure (芽毫隐藏). Color — emerald-green, oily (翠绿油润), with characteristic healthy luster.
• Dry leaf aroma: Fresh, clean, with distinct chestnut-nutty note (栗香) and light floral undertone. Aroma is persistent — preserved even in open cup.
• Liquor aroma: High, long, with clear chestnut dominance and soft vegetative-sweet background.
• Taste: Fresh (鲜), mellow (醇厚), full-bodied. Combination of pronounced sweetness, soft density, and clean aftertaste. Bitterness is practically absent. Persistent returning sweetness (回甘). Good resistance to multiple brewings (耐冲泡).
• Liquor color: Apricot-green (杏绿), bright, transparent, with living luminescence.
• Spent leaves: Tender-green (嫩绿), bright, uniform. Leaves unfold whole, elastic, without damage.

7. Chemical Composition:

According to data from the Tea Quality Supervision and Testing Center of China’s Ministry of Agriculture (农业农村部茶叶质量监督检验测试中心):

• Water-soluble extractive substances: 44.7–49.5% — exceptionally high indicator ensuring taste richness and multiple brewing.
• Amino acids: 4.6–6.4% — significantly above average for green teas (typical values: 2–4%). This indicator is responsible for the pronounced sweetness and “umami” note of Tongbai Yu Ye.
• Polyphenols (catechins): Moderate content, which combined with high amino acid levels gives optimal taste ratio “sweetness/astringency.”
• Alkaloids: Caffeine (~2.5–3.5% dry mass), theobromine — in trace amounts.
• Crude fiber and ash content: Relatively low — sign of high raw material quality (tender buds and young leaves).
• Vitamins: C, B₁, B₂, E, K. High vitamin C content is characteristic of flat green teas with gentle wok fixation.
• Minerals: Potassium, phosphorus, manganese, zinc. Selenium — noted as a significant microelement of Tongbaishan mountain soils.

8. Health Properties:

• Antioxidant protection: Catechins and vitamin C jointly provide powerful neutralization of free radicals.
• Immune support: Tea polyphenols enhance antiviral activity of immune cells.
• Toning and concentration: Gentle synergistic effect of caffeine and L-theanine provides steady alertness without “nervousness.”
• Digestive support: Stimulation of enzyme secretion, mild choleretic effect.
• Cardioprotection: Regular green tea consumption is associated with maintaining healthy cholesterol and blood pressure levels.
• Anti-aging action: Antioxidant complex slows cellular aging — especially pronounced with high amino acid content characteristic of Tongbai Yu Ye.
• Radioprotection: Traditionally noted property of green tea, related to polyphenols’ ability to bind certain radionuclides.

Important to consider individual caffeine sensitivity. People with increased stomach acidity should not drink green tea on empty stomach.

9. Brewing:

• Water temperature: 75–85°C. For highest grades (single buds) — 75–80°C; for standard — up to 85°C.
• Tea amount: 3 g per 150 ml (gaiwan); 5 g per 200–250 ml (glass cup).
• Teaware: Porcelain gàiwǎn (盖碗) — best choice for revealing chestnut aroma and controlling extraction. Glass cup — for daily tea drinking and visual enjoyment: flat Tongbai Yu Ye leaves beautifully “float” in water.
• Process:
  1. Warm teaware with boiling water and drain.
  2. Add tea, gently shake gaiwan to release dry leaf aroma.
  3. First infusion: 80°C, along wall, steep 20–25 seconds. Leaves unfold, liquor acquires tender apricot-green tone.
  4. Second–third infusions: 25–35 seconds. Taste peak — body fullness, chestnut sweetness, persistent aftertaste.
  5. Fourth–sixth infusions: 40–60 seconds, add 10–15 seconds each. Aroma moves to soft floral-herbaceous register.
  6. When steeping in glass: 2–3 g per 200 ml, 2–3 minutes, can refill water 2–3 times.

10. Storage:

• Store in airtight container, protecting from light, moisture, heat, and foreign odors.
• Optimal — in refrigerator at 0–5°C in vacuum foil packaging. Before opening — let package warm to room temperature (15–20 minutes) to avoid condensation.
• Recommended consumption period: 6–12 months after production. Chestnut aroma of flat green teas is most expressive in first 4–6 months.
• Freezer storage (−18°C) is permitted for long-term supply — up to 18 months without noticeable quality loss.

11. Price and Counterfeits:

• Price category: Medium — premium. Early spring batches from single buds (明前茶) — significantly more expensive than mass grades. Tea from “wild” mountain massifs (野生茶) — separate, more expensive niche.
• Price factors: Season and picking grade, tea tree age (wild — more expensive), hand vs. machine processing, specific farm.
• How to avoid counterfeits:
  • Buy from producers having rights to use “Tongbai Yu Ye” geographical indication mark.
  • Check appearance: authentic Tongbai Yu Ye — flat, smooth, with “hidden” down and oily luster. Counterfeits often have uneven surface or coarse texture.
  • Liquor should be apricot-green and transparent, without turbidity and brown tones.
  • Aroma — clean chestnut, without chemical “perfumery.”
  • Suspiciously low price for “premium spring” tea — sign of raw material substitution from other regions or use of summer-autumn leaves.

12. Interesting Facts:

• The tea’s original name was “Shuilian Yu Ye” (水帘玉叶, “Jade Leaf of Water Curtain”) — after the Shuiliandong Waterfall (水帘洞) at the foot of Taibai Peak. Later the tea was renamed “Tongbai Yu Ye” to strengthen regional brand identity.
• Tongbai is one of central China’s oldest tea regions, claiming status as “birthplace of tea culture”: local legends connect the activities of mythical Shen Nong with the Tongbaishan Mountains.
• The Tóngbǎi Tea Breeding Station (桐柏茶种场), established in 1962 with involvement of scientists from Henan Agricultural University, is the largest tea seedling nursery in China’s north-central tea region, annually producing more than 10 million cuttings.
• In 2017, Tongbai attracted Hunan’s “Zuzu Yinxiang Group” (茶祖印象集团) to create “Zuzu Tea Town” (茶祖小镇) — Henan’s largest tea-tourism complex combining production, science, culture, and recreation, with investments of 2.1 billion yuan.
• Connoisseurs compare Tongbai Yu Ye with Xi Hu Longjing, noting that the Henan tea does not yield to its Zhejiang “elder brother” in aroma purity and taste sweetness, while winning in extractive substance richness.

13. Comparison with Other Green Teas:

• Xī Hú Lóngjǐng (西湖龙井, Xīhú Lóngjǐng): The benchmark flat green tea from Zhejiang. Both teas are flat, smooth, chestnut-aromatic. Longjing is usually lighter, with more pronounced “beany” tone; Tongbai Yu Ye is slightly denser, sweeter, and with higher extractive content (up to 49.5% versus ~36–40% for standard Longjing).
• Xìnyáng Máojiān (信阳毛尖, Xìnyáng Máojiān): Another famous Henan green tea, but needle-shaped (条形), not flat. More downy, with pronounced fresh “green” note. Tongbai Yu Ye is smoother, more chestnut-like, and oilier.
• Méngdǐng Gānlù (蒙顶甘露, Méngdǐng Gānlù): Twisted green tea from Sichuan, also with high amino acid content. Profile is more floral-sweet and “dewy”; Tongbai Yu Ye is drier in tone, with more distinct chestnut “core.”
• Tàipíng Hóukuí (太平猴魁, Tàipíng Hóukuí): Large-leaf flat green tea from Anhui. Completely different aesthetic — long, large leaf with orchid aroma. Tongbai Yu Ye is more compact, denser in texture, and with chestnut rather than orchid note.

In Conclusion:

Tongbai Yu Ye is a flat green tea that carries both the ancient history of the Tongbaishan Range and the ambitions of the modern “Tea Heart of the Central Plain.” Its main assets are the impeccably smooth leaf, exceptionally high amino acid and extractive content (almost 50%), persistent chestnut aroma, and soft, long sweetness. For those who love Longjing but want to discover something new — Tongbai Yu Ye will be an excellent introduction to Henan’s tea tradition, little known outside China.
