Manlyu Dashan (曼吕大山, Mànlǚ Dàshān) is a line of raw (sheng) pu-erh produced under the Boyou (博友, Bóyǒu) brand and named after a mountain tea massif near the Dai village of Manlyu in southern Yunnan Province. The raw material is harvested in the mountains of the Xishuangbanna Dai Autonomous Prefecture, within the belt of large-leaf Yunnan tea, the leaves of which are traditionally pressed into pu-erh cakes. Like other “single-mountain” pu-erhs, the line is oriented toward conveying the character of a specific terroir: a dense taste with noticeable but quickly dissipating bitterness and a long sweet aftertaste. The full trade name is Boyou Manlyu Dashan sheng bing (博友曼吕大山生饼), i.e. a raw pressed cake from Manlyu Mountain by the Boyou brand. In the general hierarchy of pu-erh, such “village” positions occupy an intermediate place between mass-produced factory tea and premium branded mountains like Laobanzhang (老班章, Lǎobānzhāng) or Bingdao (冰岛, Bīngdǎo).

1. Classification and Origin:

Type: Raw pu-erh (生茶, shēng chá), not having undergone artificial accelerated fermentation (渥堆, wòduī); pressed cake (饼茶, bǐngchá).
Category: Pu-erh (普洱茶, pǔ’ěr chá).
Cultivar of Raw Material: Yunnan large-leaf tea (云南大叶种, Yúnnán dàyèzhǒng) — a variety of Camellia sinensis var. assamica.
Origin: mountain massif near Manlyu Village (曼吕, Mànlǚ), Menghai County (勐海县, Měnghǎi xiàn), Xishuangbanna Dai Autonomous Prefecture (西双版纳傣族自治州), Yunnan Province (云南省), China.
Form: classic 357g cake in the “seven cakes” format (七子饼, qīzǐbǐng); less commonly, other formats.

According to producer descriptions, Manlyu Village is classified within the Menghai tea area; many sources associate it with the high-mountain Mengsong region (勐宋, Měngsòng) — one of the most elevated tea areas in Xishuangbanna. The word “dashan” (大山, “big mountain”) in the name indicates not an official toponym, but the mountainous tea gardens around the village. Pu-erh as a product with geographical indication is governed by the PRC national standard GB/T 22111-2008: only tea from a defined list of Yunnan regions, which includes Xishuangbanna, may be sold under this name.

2. History and Cultural Significance:

Brand: Boyou (博友, Bóyǒu) — the trademark/workshop under which this line is released; Manlyu Dashan is its single-mountain position.
Tradition Category: “Mountain-top tea” (山头茶, shāntóu chá) — a trend that took shape in the 2000s.

Pu-erh as a category evolved over centuries around the trade of pressed tea along the “Tea Horse Road” (茶马古道, chámǎ gǔdào), but the modern culture of single-mountain pu-erhs is a relatively young phenomenon. Since the 2000s, the market has shifted from anonymous factory blends toward tea specifying a particular village or mountain, valuing the age of trees, the ecology of the locality, and the “legibility” of terroir in the cup. Positions like Manlyu Dashan are a typical product of this wave: they lack centuries-old brand history but rely on the region’s reputation and the growing interest in lesser-known Menghai gardens lying in the shadow of hyped mountains.

3. Botanical Description and Raw Material:

Species: Camellia sinensis var. assamica — large-leaf Assam variety.
Plant Form: predominantly arboreal and semi-arboreal bushes (乔木/小乔木, qiáomù / xiǎoqiáomù).
Raw Material: fresh leaf with bud; for quality batches, the standard of “bud and two or three leaves” is declared.
Tree Age Categories: from middle-aged plantings to old trees (古树, gǔshù); the actual composition depends on the specific batch.

The large-leaf variety is distinguished by a long (often 10–15 cm or more) leaf, pronounced down on young buds (白毫, báiháo), and a high content of extractive substances, which determines the density and endurance of pu-erh infusion. It is important to understand that the designation “dashan” or “gushu” on the packaging does not by itself guarantee old-tree raw material — the actual age of the plants is confirmed only by origin and organoleptics.

4. Terroir and Cultivation Features:

Altitude: approximately 1500–1900 m above sea level (characteristic of the high-mountain gardens of Mengsong).
Climate: subtropical monsoon, with a distinct division into wet (May–October) and dry (November–April) seasons.
Precipitation and Temperature: approximately 1300–1600 mm of rainfall per year, average annual temperature around 18–21 °C.
Soils: mountain red-yellow and brown soils, acidic, with high organic content under the forest canopy.

The highlands of Mengsong provide frequent mists, significant daily temperature fluctuations, and diffused light — conditions that slow shoot growth and promote the accumulation of aromatic compounds and amino acids. The combination of mountain coolness and a thick layer of forest litter shapes the profile characteristic of the area: a dense body of the infusion, a noticeable fresh bitterness, and a “mountain” herbal-honey aromatic.

5. Production Technology:

Processing Type: the raw material is prepared as sun-dried maocha (晒青毛茶, shàiqīng máochá), then pressed into a cake.

Production proceeds in two stages. First, a loose semi-finished product is obtained from the fresh leaf: picking (采摘, cǎizhāi) → withering (萎凋, wěidiāo) → fixation of greenery by heating in a wok (杀青, shāqīng) → rolling (揉捻, róuniǎn) → sun-drying (晒干, shàigān). The key difference from green tea is the gentle fixation temperature, at which enzymes are not fully deactivated, preserving the tea’s ability for subsequent slow maturation.

Then the maocha goes for pressing: a weighed portion is steamed (蒸压, zhēngyā), shaped into a cake in a cloth bag using a stone or screw press, then slowly dried. For a more gentle variant, stone molds (石模, shímó) and natural drying are used. The finished cake is still a raw pu-erh, and its taste will change over the years.

6. Organoleptic Characteristics:

Dry Leaf: dark green with brown and silvery tones, tightly twisted, with noticeable downy buds.
Infusion: from light golden with greenish hue (in young tea) to a richer golden with age; transparent.
Aroma: floral-honey, with notes of mountain herbs, sometimes light fruitiness.
Taste: dense, with a noticeable initial bitterness and astringency (苦涩, kǔsè), which quickly give way to sweetness.
Aftertaste: pronounced returning sweetness (回甘, huígān) and abundant salivation (生津, shēngjīn), a pleasant sensation in the throat (喉韵, hóuyùn).

For the Mengsong area, a “legible” bitterness is typical, which does not linger in the mouth for long but transforms into sweetness — in this it differs from the softer neighboring gardens. Many connoisseurs also note a palpable “tea energy” (茶气, cháqì) — a warming and invigorating bodily effect, considered in Chinese tradition a sign of quality high-mountain raw material.

7. Chemical Composition:

Polyphenols (茶多酚, chá duōfēn): high in young raw pu-erh, approximately 28–35 %.
Catechins (儿茶素, érchásù): the main part of polyphenols, responsible for bitterness and astringency.
Caffeine (咖啡碱, kāfēijiǎn): approximately 3–5 %.
Amino acids (氨基酸, ānjīsuān), including theanine (茶氨酸, chá’ānsuān): around 2–4 %, provide sweetness and “umami”.
Other: soluble sugars, pectins, aromatic compounds.

The given values are approximate and depend on batch, season, and year of harvest. During aging (陈化, chénhuà), the content of free polyphenols gradually decreases due to slow oxidation, bitterness softens, and the profile shifts towards more rounded, “mature” tones — which is precisely why aged raw pu-erh is valued separately.

8. Health Benefits:

Antioxidants: polyphenols and catechins possess pronounced antioxidant activity.
Toning: caffeine combined with theanine provides mild alertness without sharp excitation.
Digestion: in Chinese tradition, raw pu-erh is drunk to relieve heaviness after fatty foods.

These effects should not be considered therapeutic. Young raw pu-erh is saturated with polyphenols and caffeine, so strongly brewed tea can be harsh on a sensitive stomach and is undesirable on an empty stomach or at night. Moderation and water quality are more important here than any “wellness” expectations.

9. Brewing:

Vessel: gaiwan (盖碗, gàiwǎn) or Yixing teapot with a volume of 100–150 ml; for terroir evaluation, a gaiwan is preferable.
Dosage: about 5–8 g per 100–150 ml (approximately 1 g per 15–20 ml of water).
Water: soft, temperature 95–100 °C; for very young and bitter tea, can be lowered to 90–95 °C to smooth out the sharpness.
Rinse: one quick (3–5 sec), then discard.

Brew using short infusions (工夫, gōngfū): the first 3–5 infusions are held for 5–10 seconds, then the time is gradually increased by a few seconds with each subsequent infusion. Quality high-mountain raw material can withstand 8–12 or more short infusions, revealing itself in waves: first aroma and bitterness, then increasing sweetness and a “throat” response. Pu-erh of this type does not tolerate long steeping — oversteeping makes the taste flatly bitter.

10. Storage:

Conditions: moderate humidity (approximately 55–70 %), temperature around 20–30 °C, absence of foreign odors and direct light.
Container: original paper wrapper and cardboard; for long-term aging, cakes are kept in a ventilated room, but without drafts.

Raw pu-erh is the only tea category designed for multi-year maturation. If the air is too dry, development proceeds sluggishly; excessive humidity may cause mold and spoilage. A reasonable guideline is a stable microclimate without sharp fluctuations, separate from coffee, spices, and perfumery. With proper storage, the character of the cake changes noticeably over decades.

11. Price and Counterfeits:

Price Level: Manlyu does not belong to the “top” names, so the position is moderately priced by the standards of single-mountain pu-erhs.
Range: a young 357g cake from mixed/plantation raw material is approximately from several hundred yuan; for confirmed old-tree raw material, it is considerably more expensive; the price strongly depends on the year and origin.

The main risks of the market are not crude fakes, but substitution of raw material and exaggeration of status. Under the name “Manlyu Dashan” and the “gushu” mark, cheaper plantation leaf (台地茶, táidì chá) or material from neighboring, less valuable gardens is often sold. Guidelines for an honest purchase: an adequate price (anomalously cheap “old-tree” tea is almost always a deception), clear information on the year and place of harvest, and the seller’s reputation. It is useful to inspect the spent leaf: good raw material is dense, elastic, whole, and uniform in color. Certificates and inserts (内飞, nèifēi; 内票, nèipiào) are easily forged, so the decisive factor remains the taste — depth, long return of sweetness, and bodily response, which are difficult to imitate with cheap material.

12. Interesting Facts:

The prefix “man” (曼, màn) in Xishuangbanna toponyms originates from the Dai language (傣族, Dǎizú) and means “village”; such names are scattered throughout the prefecture.
The Mengsong area is one of the highest tea areas in Xishuangbanna, and the altitude directly influences the density and “mountain” aromatic of local pu-erhs.
The standard cake weight of 357g is related to the “seven cakes” bundled format (筒, tǒng): seven pieces yield about 2.5 kg — this norm was consolidated in the factory era of the 20th century, although the name “seven sons” (七子饼, qīzǐbǐng) itself is older.
Raw pu-erh (生茶) and “ripe” shu pu-erh (熟茶, shú chá) are fundamentally different products: the latter undergoes artificial fermentation and is not intended for multi-year maturation in the same sense as the former.

In Conclusion:

Manlyu Dashan is a characteristic representative of the modern wave of single-mountain raw pu-erhs: a tea without a loud branded history, but relying on the real terroir of high-mountain Menghai. Its value is determined not by the name on the wrapper, but by the combination of origin, tree age, and careful processing, and is verified — in the cup, by the depth of taste, the purity of bitterness, and the length of the sweet aftertaste.

For those studying pu-erh, such positions are useful as a way to understand the “middle layer” of the market between anonymous factory tea and expensive celebrated mountains. A sensible approach here is to buy samples, trust organoleptics more than labeling, and remember that raw pu-erh does not reveal itself immediately: part of its character will only manifest after years of correct storage.
