Menghai 勐海勐海

Classification and Origin

"dragon pearls" (龙珠, lóngzhū) — hand-pressed balls weighing approximately 5–8 g each.

shaiqing maocha (晒青毛茶, shàiqīng máochá) — sun-dried semi-finished product from Yunnan large-leaf tea.

Origin: Menghai County, Xishuangbanna Dai Autonomous Prefecture, Yunnan Province, China.

Type: pu-erh (普洱茶, pǔ'ěrchá), subcategory — raw (sheng) pu-erh (生茶, shēngchá).

Facts

the Menghai Tea Factory (founded in 1940) and the Dayi brand that grew out of it are among the most influential names in the world of pu-erh.

in codes such as 7542, the first two digits indicate the year of the recipe, the third — the conventional leaf grade, the fourth — the factory code (the digit 2 corresponds to the Menghai Tea Factory).

a wild tea tree on Bada Mountain (巴达, Bādá) was estimated at approximately 1700 years old and collapsed in 2012; on Nannuoshan (南糯山, Nánnuò Shān) the Hani ethnic group (哈尼族, Hānízú) has long resided, and on Bulangshan — the Bulang ethnic group (布朗族, Bùlǎngzú).

neighbouring villages within a single county can produce tea noticeably different in strength and aroma, making Menghai a convenient ground for comparative tastings.

History and Culture

Menghai lay on branches of the Tea Horse Road (茶马古道, Chámǎ Gǔdào), which connected Yunnan with Tibet and the inland provinces; the ease of transporting pressed tea largely reinforced the tradition of compressed forms.

founding of the Menghai Tea Factory, originally called the Fohai Tea Factory (佛海茶厂, Fóhǎi Cháchǎng) — one of the oldest industrial tea enterprises in Yunnan.

refinement of the "wet-piling" technology (渥堆, wòduī) for accelerated fermentation of shu pu-erh, in which the Menghai factory played one of the leading roles.

grew out of the Menghai factory; the classic recipe blends 7542 (raw) and 7572 (ripe) became industry benchmarks.

Botany and Raw Material

Menghai large-leaf tea (勐海大叶种, Měnghǎi dàyèzhǒng) — a locally selected population.

ancient trees (古树, gǔshù), as well as plantation bushes (台地, táidì).

Cultivar: tea bush of the Assam variety (Camellia sinensis var. assamica), in the Chinese tradition — large-leaf tea (大叶种, dàyèzhǒng).

Terroir

Climate: subtropical-tropical monsoon, average annual temperature around 18 °C, annual precipitation around 1300–1400 mm.

approximately 21°28′–22°28′ N and 99°56′–100°41′ E; the county borders Myanmar.

from roughly 535 to 2429 m above sea level (the highest point being Huazhu Liangzi, 滑竹梁子, Huázhú Liángzi); most tea gardens are located at 1000–1800 m.

Bulangshan (布朗山, Bùlǎng Shān) with the villages Laobanzhang (老班章, Lǎobānzhāng) and Xinbanzhang (新班章, Xīnbānzhāng), Nannuoshan (南糯山, Nánnuò Shān), Hekai (贺开, Hèkāi), Mengsong (勐宋, Měngsòng), Bada (巴达, Bādá), Menghun (勐混, Měnghùn).

Production

flushes consisting of a bud and young leaves during the spring-autumn period.

partial withering of the fresh leaf to reduce moisture content.

heating in a wok to halt fermentation; for pu-erh this is performed at a moderate temperature to preserve activity for subsequent ageing.

shaping the leaf and releasing juices.

drying in the sun to obtain shaiqing maocha.

the maocha is lightly steamed for softening and hand-rolled into dense balls, then dried.

Organoleptic Profile

dark green twists with silvery buds, gathered into a dense ball.

from pale yellow to golden yellow for young tea, darkening with years of ageing.

floral-honey, with green and herbaceous-fruity notes in young tea.

pronounced sweet return (回甘, huígān) and salivation (生津, shēngjīn), long-lasting and persistent.

Taste: rich and dense, with perceptible bitterness (苦, kǔ) and astringency (涩, sè), especially in Bulang-type raw material.

Chemical Composition

Amino Acids: contribute to softness and "umami", balancing bitterness.

high content, characteristic of large-leaf cultivars; in fresh raw material often exceeds 30%.

the main group of polyphenols responsible for bitterness, astringency, and antioxidant activity.

approximately 3–5%.

Health Notes

caffeine and polyphenols exert a stimulating effect.

pu-erh is traditionally consumed after heavy and fatty meals.

associated with the high content of catechins.

Brewing

one pearl (5–8 g) per 100–150 ml of water.

one short rinse (5–10 seconds), which also helps the pearl to begin opening.

the first few infusions are short, 5–15 seconds, with gradual lengthening; robust raw material withstands many infusions.

Teaware: gaiwan (盖碗, gàiwǎn) or Yixing teapot (紫砂壶, zǐshāhú) with a volume of 100–150 ml, as well as a fairness pitcher (公道杯, gōngdàobēi) for serving.

Water Temperature: 95–100 °C.

Storage

a dry, ventilated place free of extraneous odours, away from direct sunlight.

moderate, stable humidity (approximately 50–70%) and absence of sharp fluctuations; excessive dampness leads to a risk of mould.

packaging that allows air passage; proximity to spices, cosmetics, and household chemicals is unacceptable.

Price and Authenticity

"Menghai" is a broad region, so the cost varies from affordable for ordinary plantation raw material to high for tea from renowned villages.

raw material from Laobanzhang and other famous villages from ancient trees costs many times more than the average and is the most commonly counterfeited.

"pearls" are sold individually or by weight; the fixed mass of a pearl is convenient for portion control.
