Jietan Lü Chá · new.thetea.app

Jietan Lü Chá (碣滩绿茶, Jiétān lǜchá) is a Hunan green tea of twisted form, a national geographical indication product (国家地理标志保护产品, guójiā dìlǐ biāozhì bǎohù chǎnpǐn, certified in 2011). It is produced in Yuánlíng County (沅陵县, Yuánlíng Xiàn) of Húnán Province (湖南, Húnán), in the Jietanshan Mountains (碣滩山) on the banks of the Yuán River (沅水, Yuán Shuǐ). This is one of China’s most ancient teas—its status as imperial tribute tea (贡茶, gòngchá) was recorded as early as the Tang dynasty. In 1972, Japanese Prime Minister Tanaka Kakuei, during his meeting with Zhou Enlai, mentioned Jietan Cha, calling it “the tea of Sino-Japanese friendship” (中日友好之茶).

1. Classification and Origin:

Type: Green tea (non-oxidized). By form—twisted-curved (卷曲形, juǎnqū xíng).
Category: Historical tribute product (唐代贡茶); national geographical indication product (2011); representative of Chinese high-quality twisted green teas.
Origin: China, Húnán Province (湖南, Húnán), Yuánlíng County (沅陵县, Yuánlíng Xiàn), Jiétān mountain region (碣滩山区). Yuanling is located in the northwestern part of Hunan, in the middle reaches of the Yuan River, at the junction of the Wǔlíng (武陵山, Wǔlíng Shān) and Xuěfēng (雪峰山, Xuěfēng Shān) mountain ranges.
Geographic coordinates: Approximately 28°25′–29°00′ N, 110°00′–111°10′ E.

2. History and Cultural Significance:

History: Yuanling’s tea tradition has ancient roots. The Western Jin treatise “Jingzhou Tudi Ji” (《荆州土地记》, Jīngzhōu Tǔdì Jì) noted: “In all seven counties of Wuling, tea grows everywhere, and it is the finest”—Yuanling was one of these seven counties. In Lu Yu’s (陆羽, Lù Yǔ) “Classic of Tea” (《茶经》, Chájīng), Pei Yuan’s “Kunyuan Lu” (《坤元录》) is quoted: “Three hundred and fifty lì northwest of Xupu County in Chēnzhōu Prefecture lies Mount Wusheshan (无射山)… on the mountain there are many tea trees.” In 2016, Mount Wusheshan, located in Yuanling County, was officially recognized by the China Tea Marketing Association and China Tea Culture Society as “China’s Historic Tea Culture Mountain.”

According to legend, in the early 8th century, Tāng Emperor Ruìzōng (李旦, Lǐ Dàn), forced to abdicate in favor of his mother—Empress Wu Zetian—traveled south. Journeying along the Yuan River, he stopped at Mount Jietan, where he met a local beauty, Hú Fèngjiāo (胡凤姣), who served him tea from the mountain gardens. Upon returning to the throne (around 710 CE), Ruizong presented Jietan tea to the court, and it was included among the annual tribute products. Thus Jietan Cha became imperial tribute tea, and was subsequently spread to Japan and India through international trade.

In “Chenzhou Fuzhi” (《辰州府志》) it is recorded: “Tea grows in many places in the county, but that from Mount Jietan is most prized.” During the Ming-Qing period, the tea was known as “Chenzhou Jietan Cha” (辰州碣滩茶). National hero Lín Zexu (林则徐), passing through Yuanling, tasted the local tea and exclaimed: “This prefecture has the first pass under Heaven, and it turns out it also has the first tea under Heaven!”

In modern history, a key event occurred in 1972: during his visit to Beijing, Japanese Prime Minister Tanaka Kakuei (田中角荣) mentioned Jiétān tea and its historical presence in Japan in conversation with Zhōu Enlai (周恩来). Zhou Enlai initiated a search for the tea, which was found on abandoned plantations in Jietanshan. Under his personal patronage, restoration of the tea gardens began in 1973. In 1980, scientific and technical work was organized to recreate the traditional technology, and by 1982—the visit of a Japanese youth friendship delegation—Jietan Cha was “revived.” The delegates called it “the tea of Sino-Japanese friendship.” In 2011, the tea received geographical indication protection, and in 2015, it won a gold medal at the Milan World Expo.
Name: “Jietan” (碣滩)—“rocky shoal”: “碣” means stone stele or vertically standing rock; “滩”—river shoal or shallow. The name comes from rock formations in the Yuan River bed, standing vertically like steles. Lü Chá (绿茶)—“green tea.” Thus, the full name is “green tea from Rocky Shoal.”
Cultural significance: Jietan Cha is one of the few teas whose tribute history is confirmed simultaneously by ancient chronicles and 20th-century events (the diplomatic episode of 1972). For Yuanling County, which holds the status of “Hometown of Famous Tea in China” (中国名茶之乡) and “Hometown of Organic Tea” (中国生态有机茶之乡), this is the territory’s main brand. The tea is also connected to the culture of “Mount Eryushan” (二酉山)—the legendary repository of knowledge that gave rise to the expression “learning of five carts and two caves” (学富五车，书通二酉).

3. Botanical Description and Raw Material:

Variety / Cultivar: Primary—local group population (本地群体种, běndì qúntǐ zhǒng), represented by ancient tea trees over 150 years old. These trees belong to the southwestern branch of Camellia sinensis var. sinensis (Yunnan-Guizhou tea group, 云贵茶叶组系), distinguished by fleshy, dense leaves with strong tenderness retention (持嫩性). Auxiliary clonal varieties for plantation expansion—Báiháo Zǎo (白毫早, Báiháo Zǎo), Bìxiāng Zǎo (碧香早, Bìxiāng Zǎo), Zhūyè Qí (槠叶齐, Zhūyè Qí).
Harvest: Spring harvest—from Spring Equinox (春分, Chūnfēn, mid-March) to Grain Rain (谷雨, Gǔyǔ, mid-April) for special and first grades. For special grade, the rule “harvested in the morning—processed in the afternoon” (上午采下午制) applies.
Harvest standard: Jiétān Yín Zhèn (碣滩银针, Jiétān Yínzhēn, “Silver Needles of Jietan”)—single bud; Jiétān Máojiān (碣滩毛尖, Jiétān Máojiān)—bud with one leaf in initial opening stage; Jiétān Cuìfēng (碣滩翠峰, Jiétān Cuìfēng)—bud with two leaves in initial opening stage.

4. Terroir and Cultivation:

Topography and location: Yuanling is located at the junction of two mountain systems—Wulingshan (武陵山) and Xuefengshan (雪峰山). The Yuán River (沅水) and Yóu River (酉水) flow through the county; the Wuqiangxi Hydroelectric Station (五强溪水电站) created Hunan’s largest artificial reservoir, forming a unique microclimate—increased humidity, stable temperature, and abundant mist. Forest coverage—76.19%. The county has over one hundred mountain peaks, more than 30 of which exceed 1000 m.
Growing altitude: 300–1000 m; main tea garden areas—at 400–600 m altitude.
Climate: Average annual temperature 16.6 °C; annual precipitation ≥ 1440 mm (highest in the Huaihua region). Clouds and mist—year-round; 911 streams and rivers create moisture-saturated air, favoring slow accumulation of amino acids and aromatic precursors in tea leaves.
Soils: Unique geological feature—extensive areas of purple shale and slate weathered soils (紫色板页岩风化土壤) with volcanic ash components. High content of zinc (Zn) and manganese (Mn) with low content of aluminum (Al) and fluorine (F). Organic matter ≥ 2.0%; pH 4.5–5.5. This rare geochemical composition is one of the reasons for the tea’s exceptionally high extractability.
Core production zone: Jietan Village, Beirong Township (北溶乡碣滩村)—the historical birthplace of the tea; high-mountain tea gardens near Jiemusi National Nature Reserve (借母溪国家级自然保护区). Total tea garden area in the county—over 150,000 mu (approximately 10,000 ha).

5. Production Technology:

Jietan Lü Cha is a twisted green tea with hand-finished processing. Key features: double rolling to form “flower-like” twisting, traditional charcoal drying using the “three dryings—three rests” principle (三烘三闷, sān hōng sān mèn), and strict adherence to a one-day production cycle for special grade.

Withering (鲜叶摊放, xiānyè tānfàng): Fresh leaves are spread in thin layers for preliminary moisture loss and activation of aromatic precursors.
Kill-green (杀青, shāqīng): Hand pan-firing at 180–220 °C with constant turning. High-temperature fixation quickly deactivates enzymes and fixes the fresh green color.
Cooling (清风, qīngfēng): Leaves are spread for cooling—the “clear wind” stage.
Primary rolling (初揉, chū róu): Light pressure for about 5 minutes; primary leaf structure is formed.
Primary drying (初烘, chū hōng): At 85–90 °C—removal of excess moisture.
Secondary rolling (复揉, fù róu): More intensive pressure for about 8 minutes; double rolling forms the characteristic “petal-like” shape (花瓣状, huābàn zhuàng).
Secondary drying (复干, fù gān): Intermediate drying.
Shaping and down revelation (整形提毫, zhěngxíng tí háo): Hand rolling-rubbing at 60–70 °C. At this stage, white down is brought to the surface, giving the tea its characteristic “snowy” appearance.
Final drying (足干, zú gān): Low-temperature slow charcoal drying at 60–65 °C. The traditional “three dryings—three rests” technique (三烘三闷) fixes the chestnut aroma and forms a unique “cold” note that manifests in the cooled cup and persists for more than 30 minutes.

6. Organoleptic Characteristics:

Dry leaf appearance: Thin, tightly twisted leaves of curved form (卷曲形); sharp tips, elegant (锋苗秀丽); color—green with oily luster (绿润); abundant silvery down covers the leaf, occasionally revealing the emerald base (银毫满披隐翠). When brewed, leaves stand vertically and float, rising and falling—“like silver fish frolicking in water” (如银鱼游翔)—considered one of the visual quality standards.
Dry leaf aroma: Dominant—chestnut aroma (栗香, lì xiāng); delicate, persistent green freshness (嫩香持久). The cooled cup retains aroma for more than 30 minutes (冷杯留香超30分钟)—a rare characteristic even among famous green teas.
Liquor aroma: Chestnut tone intensifies, gaining depth; sweet nuances of fresh baking emerge; “cold aroma” becomes even more expressive as it cools.
Taste: Pronounced freshness (鲜爽)—amino acid content ≥ 4.33%; dense, oily body (醇厚) from polyphenols 26.6–29.7%; intense and rapid returning sweetness (huí gān) (回甘显著). Characteristic feature—“to the near it seems there is no aroma, to the far it seems to be fragrant many times over” (近者因”醉”而不闻其香，远者因”渴”倒倍觉芬芳): one person brews tea—the whole house fills with aroma.
Liquor color: Yellow-green, clear and transparent (黄绿清透); possible light “milky” cloudiness from down (毫浑, háo hún).
Spent leaves (wet leaves): Tender green color, uniform, elastic; for special grade—whole vertically standing shoots.

7. Chemical Composition:

Water-soluble extractives (水浸出物): Record 49.8%—12.8 percentage points above the national standard (37%). This is one of the highest indicators among China’s green teas, explaining the exceptional density and richness of taste.
Amino acids (氨基酸): ≥ 4.33%—an outstanding indicator ensuring bright freshness and sweetness.
Polyphenols (茶多酚): 26.6–29.7%—moderately high content; polyphenol to amino acid ratio (酚氨比)—about 6–7, which is very harmonious and indicates pronounced “fresh” orientation while maintaining density.
Caffeine (咖啡碱): 4.46%.
Catechins: Total content—158.36 mg/g; EGCG and EGC predominate.
Minerals: High content of zinc (Zn) and manganese (Mn), reduced—aluminum (Al) and fluorine (F); selenium (Se) is present. This unique mineral profile directly reflects the purple shale soils.
Vitamins: Vitamin C, B-group vitamins.

8. Health Properties:

Antioxidant protection: Tea polyphenols neutralize free radicals; high EGCG content is associated with pronounced antioxidant activity.
Tonic effect: Caffeine combined with L-theanine provides smooth alertness and mental clarity.
Lipid metabolism support: Catechins and theaflavins contribute to cholesterol profile normalization.
Bone health support: According to some data, catechins stimulate osteoblast differentiation.
Oral health support: Moderate fluorine content and polyphenols help suppress dental plaque.
Digestive support: Polyphenols and amino acids normalize gastrointestinal function after meals.
Mineral enrichment: Natural zinc, manganese, and selenium from purple soils benefit the immune system and metabolism.

Important: this is general information, not medical advice.

9. Brewing:

Water temperature: 80–85 °C (boil and let cool for 2 minutes).
Tea amount: 3 g per 150 ml (glass cup) or 5 g per 120 ml gaiwan.
Teaware: Transparent glass cup—ideal for observing the “dance of silver fish”; white porcelain gaiwan—for controlling extraction and evaluating lid aroma.
Process (glass cup, middle infusion method—中投法):
1. Warm the cup with boiling water.
2. Pour water to 1/3 volume (80–85 °C).
3. Add 3 g tea, gently swirl to moisten and release aroma (浸润30秒).
4. Add water to 7/10 volume.
5. Steep for 2 minutes. For subsequent additions, increase time by 30 seconds; leave 1/3 liquor in cup before adding fresh water.
Process (gaiwan):
1. Warm the gaiwan.
2. First infusion—special grade brews without rinsing (首泡精华无需洗茶); observe leaf form—vertically standing “fish”—sign of authenticity.
3. Infusions of 15–20 seconds, increasing by 5–10 seconds. Up to 4–5 infusions.
Notes: Optimal tasting temperature—45–55 °C. Not recommended on empty stomach (tannins may irritate mucosa). Overnight tea should not be consumed.

10. Storage:

Airtight packaging; protection from light, moisture, and odors.
Optimal: 0–5 °C (refrigerator) in airtight container.
After opening—consume within one month.
New tea should be rested 5–7 days in a dark place before consumption to “rest” from production heat.

11. Price and Counterfeits:

Price category: Special grade (贡品级, “tribute level”)—Jiétān Yín Zhèn from single buds of spring harvest (春分茶)—about 1600 yuan/jin. First grade—400–800 yuan/jin. Second grade—affordable daily tea.
Price factors: Raw material grade, season (mingqian/yuqian), tree age (ancient material over 150 years—significantly more expensive), proportion of hand labor.
How to avoid counterfeits:
- Purchase from authorized producers with rights to the “碣滩茶” brand (the county has over 30 licensed enterprises).
- Verify geographical indication marking.
- Authentic Jietan Lü Cha is distinguished by abundant silvery down with “emerging emerald base” (隐翠显毫)—coarse leaf without down indicates substitution.
- Cold cup aroma test: genuine Jietan retains chestnut aroma for more than 30 minutes after emptying; fake—loses aroma within minutes.
- Suspiciously low price—reason for doubt: record extractability (49.8%) is physically unattainable with cheap low-altitude raw material.

12. Interesting Facts:

The 1972 episode is one of the most famous “tea-diplomatic” cases in PRC history: Zhou Enlai personally did not know where Jietan tea was produced and instructed the Ministry of Agriculture to search for it “from top to bottom” through the administrative hierarchy. The tea was discovered on abandoned mountain plantations, where in 1972 more than 2000 ancient tea tree stumps were excavated, confirming the antiquity of cultivation.
The unique characteristic “one drinks tea—the whole house fills with aroma” (一人品茶满屋香气) is not poetic exaggeration: high content of volatile essential oils actually creates a noticeable aromatic trail when brewing.
Water-soluble extractives—49.8%: this means almost half the mass of dry tea transfers to the liquor, which is one of the record indicators among all Chinese green teas.
In 2018, a sample of Jietan Lü Chá was accepted into the collection of the National Museum of China (中国国家博物馆) as a representative sample of modern green tea.
Míng thinker Wáng Yángmíng (王阳明, Wáng Yángmíng) in 1510, while teaching at Lóngxíng Temple (龙兴讲寺) in Yuanling, drank Jietan tea offered by students.

13. Varieties of Jietan Cha:

Jiétān Yìn Zhèn (碣滩银针, Jiétān Yínzhēn): “Silver Needles of Jietan”—highest grade, special tribute product. Single buds, form—straight, needle-like; abundant white down. Pronounced sweetness and tenderness; least bitterness. Most rare and expensive variant.
Jiétān Máojiān (碣滩毛尖, Jiétān Máojiān): Main commercial variety. Bud with one leaf, finely twisted; classic chestnut aroma, freshness and returning sweetness (huí gān). Optimal price-quality ratio.
Jiétān Cuìfēng (碣滩翠峰, Jiétān Cuìfēng): “Emerald Peaks of Jietan”—mass tea from bud with two leaves; denser, stronger taste; good brewing endurance. Positioned as daily tea.

Besides green tea, red tea (碣滩红茶) and dark tea (碣滩黑茶) are also produced under the “Jietan” brand, but green tea is the historical and most prestigious representative of the brand.

In conclusion:

Jietan Lü Cha is a tea with an amazing fate: from Tang dynasty imperial tribute through oblivion and abandonment to revival initiated by an international diplomatic episode, and further—to the status of one of China’s outstanding green teas. Its record extractability, bright chestnut aroma with unique “cold” note, and visual show of “silver fish” in a glass cup make it not only a palate pleasure but a true tea spectacle. For collectors of Chinese green teas, Jietan is a rare and valuable find: this is tea in which millennial history, unique purple terroir, and the mastery of Hunan tea makers unite in every cup.
