Yídū tiānrán fùxīn chá (宜都天然富锌茶) is “naturally zinc-rich tea” from Yidu: a green tea from the mountainous west of Yidu county-level city (宜都市), Yichang prefecture, Hubei Province. The main area is Panjiawan Tujia Township (潘家湾土家族乡). The name rests on a single trait: according to the provincial press, the township’s soils contain twice the provincial average of zinc, and the tea twice the average for China. Since 2007 the name has been protected by a geographical indication collective mark.
1. Classification and Origin
- Type: Green tea (绿茶, lǜchá) — according to reference descriptions. In the trademark register the goods are given simply as “茶”.
- Category: A health tea developed in the early 1990s; geographical indication collective mark (2007). Its second name is “高锌茶”, “high-zinc tea”.
- Origin: China, Hubei Province (湖北, Húběi), Yichang prefecture (宜昌, Yíchāng), Yidu county-level city (宜都, Yídū), Panjiawan Township; a reference book also names Wangjiafan Township (王家畈乡).
- Protection zone: The boundaries set by the rules for use of the mark are not found in the sources consulted; the register indicates only the holder’s affiliation — Yidu.
- Geographic coordinates: About 30° N and 111° E; according to material from the county people’s congress (2022), the 30th parallel passes through the township.
2. History and Cultural Significance
- History:
- 1990–1993. Reference books call the tea a new type of health tea developed by Yidu specialists under the guidance of Zhang Tangheng (张堂恒), professor at Zhejiang Agricultural University. The science and technology commissions of Yidu, Yichang and Hubei recognized it as a new scientific and technical product. According to a reference description, in November 1992 eleven specialists in tea and nutrition concluded that such a tea had been developed in the country for the first time.
- 1994. The status of a new product at the state level and of a model project of a state program. In Hubei Ribao the program is written as “星人计划” — apparently a typo for “星火计划”, the Spark Program.
- 1997. The title of a famous local brand of Hubei at the third China Agricultural Expo; a sample was handed over to the China Tea Museum. The same publication names the Hubei “Golden Cup” for consumer satisfaction, gold at the “Lu Yu” competition and the top ten famous teas of the Three Gorges area.
- 2007. On September 14 the name was registered as a geographical indication collective mark. The holder is the Panjiawan Township association of ecologically clean natural-zinc tea (宜都市潘家湾土家族乡无公害天然富锌茶叶协会).
- 2013. According to a 2015 publication on Yidu brands, the brand value in 2013 was estimated at 339 million yuan.
- 2023. In July the township gathered representatives of tea companies to discuss re-establishing the Panjiawan tea association and protecting the brand: according to the township administration, the cooperatives have many brands of their own, and the common brand is “not gathered into a fist”.
- Name: 宜都 — Yidu; 天然 — “natural”; 富锌 — “rich in zinc”; 茶 — tea.
- Cultural significance: Panjiawan is one of the twelve ethnic townships of Hubei and the only one in Yichang prefecture. The county congress names among local customs hand-made tea, the “tea-country daughters’ festival” (茶乡女儿会) and tea contests.
3. Botanical Description and Raw Material
- Variety / Cultivar: Not named in the sources consulted.
- Harvest time: Traditionally four harvests a year: spring, “first summer” (夏头茶), tea of the hot season (伏茶) and autumn, until October. In 2023 the township was moving to three harvests: without the autumn one, with the gardens “closed” in early September, so that the bushes rest before spring.
- Harvest standard and raw material requirements: No data in the sources consulted.
4. Terroir and Cultivation Features
- Region: The mountainous west of Yidu; the township (147.5 km²) borders Wufeng and Changyang counties.
- Topography: Karst — hills and ravines. The gardens are scattered in small plots among the forest, the light is diffused; the press writes of a “forest-tea” environment. Lüjia’ao Village (吕家坳村) lies amid an Ordovician stone forest.
- Growing altitude: Mainly 500–800 m (Hubei Ribao).
- Climate: Subtropical monsoon, rainy; mean annual temperature 16.3 °C, large daily temperature differences.
- Soils: According to a county agronomist — loose, mainly acidic, rich in organic matter and minerals. Zinc, according to “authoritative agencies” as retold by the press, is 98.3–119 ppm — twice the provincial average; a reference book singles out a “zinc belt” of about 70,000 mu.
- Garden area: A reference book names 33,500 mu of natural-zinc tea gardens in Yidu — in the townships of Panjiawan, Wangjiafan and others. The total tea area of Panjiawan Township is 33,000 mu according to Hubei Ribao (2023) and “more than 30,000” according to the county congress (2022). In Lüjia’ao Village — from “more than 4000” to 4650 mu.
- Care: In model gardens — hand weeding instead of herbicides, sticky traps and solar lamps instead of insecticides, organic matter instead of mineral fertilizers.
5. Production Technology
No description of the processing is found in the sources consulted. A reference book lists the product line: “zinc silver needles” (富锌银针), “zinc yunwu” (富锌云雾), “zinc improved green” (富锌优绿), zinc scented tea and tea with ginkgo; the technology of each is not described.
The general scheme for green tea, not a description of this tea:
- Spreading the leaf (摊放, tānfàng): The leaf gives off part of its moisture.
- Fixation (杀青, shāqīng): Heating stops oxidation.
- Rolling (揉捻, róuniǎn).
- Drying (干燥, gānzào).
6. Organoleptic Characteristics
The only description found is a short reference on Yidu products.
- Dry leaf appearance: Tight, elegant, even leaves with noticeable down; emerald green, with an oily sheen (条索紧秀匀整显毫，色泽翠绿油润).
- Dry leaf aroma: No separate description.
- Liquor aroma: Rich and lasting (香气浓郁持久); the reference does not specify whether of the leaf or of the liquor.
- Taste: Fresh, brisk, with a sweet aftertaste (滋味鲜爽回甘).
- Liquor color: Tender green, bright.
- Spent leaves (wet leaves): Tender green, bright (汤色、叶底嫩绿明亮).
7. Chemical Composition
According to Hubei Ribao (2023), Panjiawan tea contains 80 mg/kg of zinc against a Chinese average of 40.6 mg/kg; a reference book adds the averages for Japan (34.6) and Sri Lanka (35). The county portal later gave 60 mg/kg; that page could not be re-checked. The sources name no method, year or sample — these are claimed figures. No zinc threshold for tea under the mark is found in the documents consulted, and no other physicochemical data either.
8. Health Properties
There are no verified data on the effects of this particular tea. Advertising texts call zinc the “spark of life”, but these are words about a trace element, not studies of this tea.

11. Price and Counterfeits
No retail price data were found in the sources consulted.
- How to avoid counterfeits:
- Look for the registered name: according to the list of the provincial intellectual property administration (May 2020), it is collective mark No. 4686327, class 30, holder — the Panjiawan association, term — from September 14, 2017 to September 13, 2027.
- Check that the producer is from the west of Yidu.
- Zinc cannot be detected by taste — only by a laboratory report.
- The county congress recalled that excess pesticide residues and sugar added during processing once nearly cost the local tea its market: sweetness “with an additive” is a reason to be wary.
12. Interesting Facts
- Lüjia’ao Village is named both a core area of zinc tea and the birthplace of the red tea Yidu Yihong.
- The 2020 register lists the mark as collective, while Hubei Ribao in 2023 calls it a certification mark; the register is the primary source here.
- This is not an old tea but a development of the early 1990s.
13. Comparison with Other Teas
- Yidu Yihong Cha (宜都宜红茶): A red tea of the same county, with a shared core village.
- Hongshan Cha (洪山茶): Another Yidu tea mark, a certification mark, tied to Songmuping Town.
- Caihua Maojian (采花毛尖): A green tea of neighboring Wufeng County.
- Enshi Xicha (恩施硒茶): A Hubei name built on another soil element — selenium.
In Conclusion:
Yídū tiānrán fùxīn chá is a mountain green tea of Tujia Panjiawan, a project of the early 1990s under a collective mark since 2007. Its distinction rests on a single number — zinc, so far claimed without a method. The most reliable witnesses to it are the register, the forest gardens at 500–800 m and a short description: downy emerald leaf and a fresh taste with a sweet aftertaste.
