Yiwu (易武, Yìwǔ) is one of the most celebrated tea regions of Yunnan Province, lending its name to an entire style of sheng pu-erh characterised by a soft, honey-sweet character. Situated in the eastern part of the classic “Six Great Tea Mountains” (古六大茶山, gǔ liùdà cháshān) in Mengla County (勐腊县, Měnglà xiàn) of the Xishuangbanna Dai Autonomous Prefecture, Yiwu was historically the centre of tribute tea production (贡茶, gòngchá) during the Qing dynasty and the birthplace of renowned antique tea trademarks of the “numbered” era. Today, tea from Yiwu is regarded as the benchmark of the “gentle” pu-erh style, and material from its old trees ranks among the most expensive and sought-after on the market. The product designation “生普毛茶易武” denotes loose raw pu-erh material (maocha) from this region — a semi-finished product from which cakes are pressed, and which is itself prized as a drinking tea.

1. Classification and Origin:

Category: Pu-erh (普洱茶, pǔ’ěrchá).
Type: Sheng pu-erh (生普洱, shēng pǔ’ěr — “raw”, non-post-fermented), in the form of maocha (毛茶, máochá — loose leaf material from primary processing).
Origin: Yiwu Township (易武镇, Yìwǔ zhèn), Mengla County (勐腊县), Xishuangbanna Prefecture (西双版纳, Xīshuāngbǎnnà), Yunnan Province (云南, Yúnnán).
Cultivar: Yunnan large-leaf variety (云南大叶种, Yúnnán dàyèzhǒng), botanical species Camellia sinensis var. assamica.
Standard: Pu-erh as a geographical indication product is regulated by the national standard GB/T 22111-2008 “Product of Geographical Indication. Pu’er”.

Yiwu is not a distinct cultivar but a regional designation (style/terroir). It encompasses tea from numerous villages and micro-lots, each possessing its own recognisable profile.

2. History and Cultural Significance:

Golden Age: mid-19th to early 20th century, when Yiwu became the principal production centre of the ancient tea mountains following the decline of neighbouring Yibang (倚邦, Yǐbāng).
Tribute Tea: During the Qing dynasty, tea was sent from Yiwu to the imperial court. The trademark “Cheshunhao” (车顺号, Chēshùnhào) is said to have received an honorary plaque from the Emperor inscribed with “瑞贡天朝” (ruìgòng tiāncháo).
Tea-Horse Road: Yiwu was one of the departure points for the southern branch of the Tea-Horse Road (茶马古道, chámǎ gǔdào).

The legendary “numbered” tea houses (号级茶庄, hàojí cházhuāng) originated in Yiwu, including “Tongqinghao” (同庆号, Tóngqìnghào), “Songpinhao” (宋聘号, Sòngpìnhào), “Tongxinghao” (同兴号, Tóngxìnghào) and others. Their pressed tea from the early 20th century is now among the most expensive collectible pu-erhs in the world. After decades of decline in the mid-20th century, the region experienced a revival from the 1990s onward, as interest in old trees and “pure” provenance restored Yiwu to a status of the highest rank.

3. Botanical Description and Raw Material:

Species: Camellia sinensis var. assamica — large-leaf Assam variety.
Type of Plantings: Old trees (古树, gǔshù), middle-aged trees, and young terrace plantations (台地茶, táidìchá).
Leaf: Large, elongated, with pronounced bud down; Yiwu material often yields long, robust, dark-green twists.

Yiwu’s value is largely tied to the old trees growing individually or in small clusters within a forest environment. Such trees yield less material but produce a more complex, profound, and enduring infusion. Harvesting focuses predominantly on one bud with one or two leaves.

4. Terroir and Growing Characteristics:

Coordinates: Vicinity of Yiwu Township — approximately 22° N, 101.5° E.
Altitude: Tea gardens are mainly at 900–1400 m above sea level, with some individual high-mountain micro-lots situated higher.
Climate: Subtropical monsoon — warm, humid, with abundant rainfall and frequent fog; pronounced seasonality (dry and wet seasons).
Soils: Mountain red-yellow lateritic soils, rich in organic matter in forested areas.

Yiwu is renowned for its numerous micro-terroirs, each with its own reputation. Among the best-known micro-lots and villages are:

Mahei (麻黑, Máhēi) — classic, benchmark “soft” profile.
Luoshuidong (落水洞, Luòshuǐdòng) — sweet, elegant.
Guafengzhai (刮风寨, Guāfēngzhài) — deep, full-bodied tea from forest gardens, a village of the Yao people (瑶族, Yáozú).
Wangong (弯弓, Wāngōng) and Bohetang (薄荷塘, Bòhétáng) — prestigious high-mountain sites commanding a high price.
Gaoshanzhai (高山寨, Gāoshānzhài), Dingjiazhai (丁家寨, Dīngjiāzhài) — well-known villages of the area.

Many gardens are not monocultural plantations but trees scattered within the forest, which influences the taste and is esteemed by connoisseurs.

5. Production Technology:

Plucking (采摘): Hand-plucking of one bud with one or two leaves, predominantly in spring.
Withering (摊晾, tānliàng): Leaves are spread out to lose some moisture and become supple.
Fixation (杀青, shāqīng): Hand pan-frying at moderate temperature to halt oxidation; a critical and most responsible stage.
Rolling (揉捻, róuniǎn): Shaping the leaf twist and disrupting cell walls.
Sun-Drying (晒青, shàiqīng): Drying under the sun — a vital characteristic distinguishing pu-erh raw material and leaving active enzymes for subsequent aging.

The result of these stages is maocha (毛茶), i.e., loose raw sheng pu-erh material. It is in this form that the product “生普毛茶易武” is sold. Maocha is subsequently pressed into cakes (饼, bǐng), bricks, and other shapes; pressing involves steaming, moulding, and re-drying.

6. Organoleptic Characteristics:

Dry Leaf: Long dark-green twists, often with golden buds; aroma is clean, honey-floral.
Infusion: Pale yellow to light golden, transparent, darkening with age.
Aroma: Honey, floral, occasionally fruity notes; freshness without harshness.
Taste: Soft, sweet, with relatively low bitterness and astringency for Yunnan tea; pronounced returning sweet aftertaste (回甘, huígān) and abundant saliva production (生津, shēngjīn).
Body: Dense, mouth-coating, “smooth”.
Spent Leaf: Soft, elastic, evenly coloured, large.

The hallmark of the Yiwu style is restrained strength coupled with great depth: the tea does not strike with bitterness but unfolds through aftertaste and endurance across infusions. Connoisseurs describe its character with the word “柔” (róu — soft, supple).

7. Chemical Composition:

Tea Polyphenols (茶多酚, cháduōfēn): High content, characteristic of the large-leaf variety; largely preserved in sheng pu-erh.
Catechins (儿茶素, érchásù): The main group of polyphenols in young sheng.
Amino Acids (茶氨酸, chá’ānsuān and others): Contribute sweetness and umami, softening the taste.
Caffeine (咖啡碱, kāfēijiǎn): Present in significant amounts.
Sugars, Pectins, Minerals: Form the density of the infusion and sweetness.

With aging, polyphenols and catechins gradually oxidise and transform; the composition shifts towards darker compounds, changing the colour, taste, and aroma.

8. Health Properties:

Toning: Due to caffeine, it gently invigorates and enhances concentration.
Antioxidants: Polyphenols possess pronounced antioxidant activity.
Digestion: Pu-erh is traditionally drunk after meals; it is credited with supporting digestion.
Hydration and Moderation: Like any tea, it is best drunk in moderation.

It should be understood that the above are general properties of tea and observations from tea tradition, not medical recommendations. Young sheng pu-erh is quite active, and people with sensitive stomachs should avoid drinking it strong and on an empty stomach.

9. Brewing:

Vessel: Gaiwan (盖碗, gàiwǎn) or Yixing clay teapot (紫砂壶, zǐshāhú).
Water: Soft, temperature around 95–100 °C (full boiling water is acceptable for sheng pu-erh, but delicate Yiwu material also reveals itself well with slightly cooled water).
Ratio: Approximately 7–8 g per 100–150 ml.
Rinse: Quick 5–10 second infusion to “awaken” the leaf.
Infusions: First steeps 5–10 seconds, then gradually lengthening the time.
Number of Infusions: Quality material from old trees can withstand 10–15 or more infusions, gradually revealing sweetness and honey tones.

For maocha, infusion in a gaiwan is convenient: this makes it easier to follow the unfolding of taste from steep to steep. It is advisable not to oversteep the first infusions, so as not to lose the delicacy characteristic of Yiwu.

10. Storage:

Conditions: Well-ventilated place free of foreign odours, stable temperature.
Humidity: Moderate, approximately 55–70%; excessive dampness leads to mould, while excessive dryness slows and impoverishes aging.
Light: Protect from direct sunlight.
Odour Isolation: Tea readily absorbs surrounding aromas.

Sheng pu-erh is intended for long-term aging: over time it darkens, loses sharpness, and acquires softness, depth, and “dried-fruit” tones. Loose maocha ages faster than pressed tea but also loses volatile aroma more quickly; for this reason, material intended for long-term storage is usually pressed into cakes.

11. Price and Counterfeits:

Price Level: Yiwu material is among the most expensive in Yunnan; tea from the old trees of certain micro-lots (Bohetang, Wangong, Guafengzhai) belongs to the premium segment.
Range: Price strongly depends on the specific village, tree age, season, and year; ordinary material costs orders of magnitude less than top micro-lots.

Precisely because of its high cost, Yiwu is a frequent target of falsification. Typical methods include: passing off tea from other areas as Yiwu, selling terrace plantation material (台地茶) under the guise of old trees (古树), and attributing ordinary tea to the prestigious names of famous villages. Reliably determining exact provenance by appearance is virtually impossible; therefore, one should rely on the seller’s reputation, tasting, and consistency of procurement from a single supplier. Indirect indicators of quality Yiwu include: a clean honey-floral aroma, a soft entry, pronounced and long huígān, abundant shēngjīn, dense body, and endurance across many infusions without coarse bitterness. A suspiciously low price for a “top village” is an almost certain sign of misrepresentation.

12. Interesting Facts:

Style Benchmark: The “softness” of Yiwu is often contrasted with the “strength” and bitterness of teas from the western bank of the Lancang River (e.g., Menghai area), forming two classic poles of pu-erh taste.
Forest Gardens: Some of the most expensive material comes from trees growing not in rows but scattered among the forest, complicating harvesting and increasing the price.
Ethnic Groups: Harvesting and processing in several villages is carried out by representatives of the Yao (瑶族) and other ethnic groups of the region.
Collectible Classics: Antique pressings from Yiwu’s “numbered” houses are a benchmark for the entire aged pu-erh market.
Market Nomenclature: The prefix “正山” (zhèngshān — “true mountain”) in names underscores provenance from the historical core of the Yiwu region.

In Conclusion:

Yiwu holds a special place in the world of pu-erh as the birthplace of the “gentle” style and as the historical centre from which emerged the legendary tea houses and the bulk of collectible classics. Its material is prized not for brute power, but for balance: a soft entry, honey sweetness, a deep returning aftertaste, and an endurance that unfolds from infusion to infusion.

The product “生普毛茶易武” is a loose sheng pu-erh from this region, suitable both for drinking fresh and for laying down to age. When purchasing, it is sensible to be guided not by prestigious village names alone, but by the integrity of the source and one’s own impressions from the cup, as it is precisely in the Yiwu segment that price and reputation render the market especially vulnerable to substitution.
