Yúnnán Xiàguān tuóchá

Yúnnán Xiàguān tuóchá (云南下关沱茶) is a pressed pu-erh in the shape of a thick-walled bowl from Xiaguan in Dali county-level city in the west of Yunnan Province. From the concave side it looks like a small bowl, from the convex side like a round bun. The Xiaguan trading houses gave the form its canonical shape in 1902, starting from the old Yunnan tea balls, and since then the tuo has been named after its birthplace. The making technique is entered on the national list of intangible heritage, and Xiaguan tuo of the “松鹤” brand has had a mark of origin since 2002.

1. Classification and Origin

• Type: Pressed tea (紧压茶, jǐnyāchá) of the “tuo” form: round outside, concave inside, like a mortar bowl. The raw material is Yunnan large-leaf sun-dried tea (晒青毛茶); descriptions by the producer and the press classify Xiaguan tuo as pressed pu-erh. Both sheng and shu are made; the protection regime does not specify the variant.
• Category: Historical pressed pu-erh of Yunnan; a historical mark of origin of the inspection and quarantine system; the making technique is national intangible heritage.
• Origin: China, Yunnan Province (云南, Yúnnán), Dali Bai Autonomous Prefecture (大理白族自治州), Dali county-level city, Xiaguan (下关, Xiàguān).
• Protection zone: The register names Dali county-level city; I have not seen the legal boundary of the mark in the documents found.
• Geographic coordinates: Xiaguan — about 25.6° N and 100.2° E.

2. History and Cultural Significance

• History:
  • Ancestors of the form. According to the producer’s description, the tuo grew out of the Ming “pu-erh ball” (普洱团茶) and the Qing balls — “maiden’s tea” (女儿茶, also called 姑娘茶) and tea “in the shape of a mooncake”.
  • 1902 — the canon. The Xiaguan trading houses “永昌祥” and “茂恒”, building on the tuan balls, gave its canonical shape to the form “round outside, concave inside” — the mortar bowl. The founder of “永昌祥”, Yan Zizhen (严子珍), was the head of the first of the “four families” of the Xizhou merchant clan. The Xiaguan shops at once began making tuo in batches and sending it to Sichuan. In 1908 “永昌祥” opened its first tea processing factory in Xiaguan.
  • Trade hub. According to the producer’s description, caravans carried tea from Xishuangbanna, Lincang and Pu’er to Xiaguan, and from there, already pressed, to Sichuan, Tibet and beyond. In the best years more than forty tea trading houses worked in Xiaguan.
  • 1941 — the factory. In March the Mongolian and Tibetan Affairs Commission, together with the Yunnan tea trading company, opened the Kang-Zang Tea Factory (康藏茶厂) in Xiaguan — the predecessor of today’s Xiaguan Tea Factory. It made pressed tea for Tibet and tuo for Sichuan.
  • 1950s. The factory became state-owned and took in the private tea houses of Xiaguan — together with their masters, techniques and brands.
  • After the reforms. “Yunnan tuo” was exported — to France, Spain, the Netherlands, Italy, Britain, Japan and Hong Kong, in all to more than twenty countries and regions.
  • 2002. Xiaguan tuo of the “松鹤” brand was registered as a product with a national mark of origin. In the Yunnan provincial list as of 28 December 2019 this mark is under No. 7; whether it is valid now is not confirmed.
  • 2011. In May the State Council entered the making technique of Xiaguan tuo on the national list of intangible heritage.
  • 2022. The technique turned 120 years old. In November it became part of the element inscribed on the UNESCO list, “Traditional tea processing techniques and associated social practices in China”.
• Name:
  • “Xiaguan” (下关) means “lower pass”, a town in Dali.
  • “Tuo” (沱, tuó) is the name of the form; an explanation of the word itself is not found in the sources consulted.
• Cultural significance: Xiaguan tuo is an example of how a trading town, not a tea garden, gave its name to a tea. The Xiaguan trading houses exported tuo to Sichuan (including Chongqing), Tibet and the countries of Southeast Asia; after the reforms it began to be exported to Europe as well.

3. Botanical Description and Raw Material

• Variety / Cultivar: Yunnan large-leaf tea (云南大叶种, Yúnnán dàyè zhǒng). Specific varieties are not named in the sources consulted.
• Harvest: The timing of picking the raw material is not stated in the sources consulted.
• Harvest standard: Not given in the sources consulted.
• Raw material requirements: Select Yunnan large-leaf sun-dried tea. According to the press, raw material of the highest grades has been used for tuo since 1902.

4. Terroir and Cultivation Features

• Region: Xiaguan is not a tea garden but a town of processing and trade on the old caravan routes. The raw material comes from the tea areas of Yunnan.
• Altitude, soils, climate: Not specified for the raw material in the sources consulted.
• Features: The technology includes aging of the raw material and of the finished tea in a “highland warehouse” (高原仓, gāoyuán cāng) — this is what the producer calls its aging warehouses.

5. Production Technology

According to the description of the technique entered on the heritage list — more than ten operations:

• Aging the raw material in a highland warehouse (高原仓陈化).
• Sieving (筛分 — shāifēn) and picking out (拣剔 — jiǎntī).
• Blending (拼配 — pīnpèi).
• Weighing (称茶 — chēngchá): A portion for one tuo.
• Steaming (蒸茶 — zhēngchá): The raw material is softened with steam.
• Shaping (揉茶 — róuchá).
• Pressing (压制 — yāzhì) and removing the bag (解袋 — jiědài).
• Drying (干燥 — gānzào).
• Packing and aging in a highland warehouse (高原仓陈储).

Pressing was mechanized step by step: in 1954 the factory’s technicians made a wooden lever press that raised output fourfold; in 1959 — the first tuo press with an eccentric mechanism; in 2017 — a program-controlled press.

6. Organoleptic Characteristics

• Dry leaf appearance: A thick-walled bowl: from the concave side — like a small bowl, from the convex side — like a round bun.
• Dry leaf aroma: No description found in the sources consulted.
• Liquor aroma: No description found in the sources consulted; it depends on the variant — sheng or shu — and on aging.
• Taste: No description found in the sources consulted.
• Liquor color: No description found in the sources consulted; it depends on the variant.
• Spent leaves (wet leaves): No description found in the sources consulted.

7. Chemical Composition

Data specifically on Xiaguan tuo are not found in the sources consulted. In general terms, sheng changes over the years, while shu, which has gone through moist aging, differs from sheng in its polyphenol composition; these are properties of the pu-erh variants, not a measurement of this tea.

8. Brewing

Class practice for pressed pu-erh.

• Water temperature: 95–100 °C.
• Tea amount: 5–8 g per 110–150 ml.
• Teaware: A gaiwan or a clay teapot.
• Process:
  1. Break off a piece of the tuo with a knife or a pick, trying not to crumble the leaf.
  2. Warm the teaware.
  3. Rinse the tea with boiling water once or twice: a dense piece does not open at once.
  4. First infusions — 10–20 seconds.
  5. Pour off completely.
  6. Increase the time with each infusion.

9. Storage

Class practice for pu-erh. In a dry, clean, ventilated place without light or foreign odors, in paper packaging. Sheng changes over the years and is often aged; shu is also drunk right away.

10. Price and Counterfeits

Price data are not found in the sources consulted; the price depends on the variant, aging and year.

• How to avoid counterfeits:
  • Look for the producer’s brand and the mark of origin.
  • Check the place of production: Xiaguan, Dali county-level city.
  • Remember that the word “沱茶” by itself is the name of a form: tuo is also made by other factories in Yunnan, and historically in Chongqing too.

11. Interesting Facts

• From 1902, Xiaguan tuo was shipped to Sichuan in batches.
• In 1941 the factory in Xiaguan was founded by the Mongolian and Tibetan Affairs Commission.
• The factory made its first lever press for tuo out of wood in 1954.
• In 2024 the Xiaguan Tea Factory was included in the sixth list of national industrial heritage.
• The Xiaguan tuo technique is part of the UNESCO element on traditional tea processing in China.

12. Comparison with Other Pu-erhs and Pressed Teas

• Chongqing Tuocha (重庆沱茶): Tuo of the Chongqing Tea Factory, from raw material of Chongqing and southern Sichuan; Xiaguan is the Yunnan source of the form.
• Xiaofa Tuo (销法沱): A separate product of the same Xiaguan factory — tuo made for sale to France.
• Pu-erh Cakes (普洱饼茶): The most common form of pressed pu-erh — a flat round cake; tuo is a bowl with a hollow.

In Conclusion:

Yúnnán Xiàguān tuóchá is a tea in which what matters most is form and craft. Select large-leaf raw material, blending, steam, the press and aging in a highland warehouse produce a dense, thick-walled bowl, which the Xiaguan trading houses canonized in 1902. Behind it stand more than a hundred and twenty years of Xiaguan’s work as a tea town on the caravan routes of Yunnan.
