Facts

Facts: Interesting Facts

• The Nanmeng River divides the area not merely territorially but also in terms of taste: "eastern" and "western" Mengku represent almost two different characters of tea from the same bush cultivar.
• Mengku Da Xueshan is known as one of the highest-altitude areas of wild ancient tea trees surveyed in the late 20th century.
• "Chunjian" is first and foremost a language of quality, inherited from the old trading classification; the same logic of dividing the spring harvest by tenderness can be traced in Yunnan documents of the 19th century.
• Bingdao is part of Mengku, which is why many descriptions of "Mengku" and "Bingdao" partially overlap, although the prices differ by multiples.
• For young sheng, porcelain and gaiwan are often preferred over clay specifically because the aim is to capture the fresh floral-honeyed aroma without smoothing it over.

In conclusion:

Mengku Chunjian is neither a brand nor a single recipe, but a regional style of raw pu'er: loose-leaf spring sheng of the highest tenderness from the Mengku area in Shuangjiang County. It is recognised by the large-leaf cultivar Mengku Da Ye Zhong, by its full-bodied taste with characteristic bitterness, and by its powerful, lingering return of sweetness, behind which lies the terroir of high-mountain Lincang with its fogs, temperature swings, and division into eastern and western slopes.

For an introduction to Lincang pu'er, this tea is an excellent starting point: it gives a cle

History and Culture

the full name of the county is Shuangjiang Lahu-Va-Bulang-Dai Autonomous County; it is inhabited by the Lahu (拉祜族), Va (佤族), Bulang (布朗族) and Dai (傣族) peoples, among whom tea cultivation and everyday tea drinking go back many generations.

in 1997, an extensive area of wild ancient tea trees was surveyed on the Mengku Da Xueshan (勐库大雪山, Měngkù Dàxuěshān) massif at altitudes of approximately 2200–2750 m — one of the largest and highest-altitude known communities of its kind.

according to local records, the cultivation of cultivated tea in Bingdao dates back to the Ming dynasty (late 15th century); today Bingdao is both a benchmark and the most expensive name in the area.

Botany and Raw Material

Mengku Da Ye Zhong — a large-leaf Assamica variety, distinguished by large leaves, a high content of extractive substances, and good downiness of the bud.

blade is large, leathery, with pronounced venation; bud is plump, covered with silvery down.

Mengku Da Ye Zhong was included in the list of approved national improved tea bush cultivars of China in the 1980s.

early spring, flushes of enhanced tenderness — a bud with one, more rarely two, young leaves.

Terroir

Climate: subtropical monsoon, with a noticeable diurnal temperature range, abundant fog and moisture, which contributes to the accumulation of aromatic and extractive substances.

Soil: predominantly red-yellow weathered soils on an acidic base, well-drained on slopes.

Mengku tea gardens are situated mainly at altitudes of roughly 1000–2000 m and above; the main peak of the massif reaches about 3200 m.

the valley of the Nanmeng River (南勐河, Nán Měng hé) divides the area into the Eastern Half-Mountain (东半山, dōng bàn shān) and the Western Half-Mountain (西半山, xī bàn shān).

Production

hand-picking of tender flushes in early spring.

spreading the leaves in a thin layer (摊晾/萎凋, tānliàng/wěidiāo) to lose part of the moisture.

pan-firing (杀青, shāqīng) at a moderate temperature — lower than in the production of green tea, in order to partially preserve the enzymatic activity necessary for subsequent maturation.

hand or machine rolling (揉捻, róuniǎn).

final drying in the sun (晒干, shàigān) — it is this stage that yields "shaiqing maocha" (晒青毛茶, shàiqīng máochá), the raw material for pu'er.

Organoleptic Profile

dark green with an olive tint, with a noticeable proportion of pale downy buds; even and tender for large-leaf raw material.

from pale yellow to golden-yellow, transparent and bright in young tea.

fresh, floral-honeyed, with fruity and herbaceous nuances; aged tea develops deeper, more mature tones.

Taste: full-bodied and dense, with the bitterness and astringency characteristic of Mengku, which quickly give way to a powerful returning sweet aftertaste.

Chemical Composition

high for large-leaf raw material, approximately 30–36% in fresh sheng; their proportion decreases over time.

a significant portion of the polyphenols, responsible for astringency and the puckering effect.

approximately 3–5%.

approximately 2–4%, including theanine; their ratio to polyphenols largely determines the balance of sweetness and bitterness.

shape the fullness of body and the sweet component.

Health Notes

due to the high content of polyphenols and catechins.

attributable to caffeine; young sheng is noticeably invigorating.

in Chinese tradition, pu'er is drunk after rich and fatty meals.

Brewing

soft, freshly boiled; temperature around 90–95 °C for young tea (to soften the bitterness) and up to 95–100 °C for more aged tea.

approximately 5–7 g per 100–150 ml.

one quick rinse of the leaf (a few seconds), the infusion is discarded.

gongfu-style brewing with short steepings — the first ones 5–10 seconds, with gradual lengthening; quality raw material withstands ten or more infusions.

Teaware: gaiwan (盖碗, gàiwǎn) or porcelain — optimal for young sheng, as they reveal the aroma and do not "swallow" the notes; a clay teapot (紫砂壶, zǐshā hú) is used with more caution.

Storage

Light: avoid direct sunlight.

a dry, ventilated room free of extraneous odours, away from the kitchen, perfumery and household chemicals.

moderate and stable; sharp fluctuations and dampness are undesirable.

Price and Authenticity

very wide. Mass-produced plantation raw material from Mengku is affordable; tea with the designation of specific villages and especially from ancient trees costs many times more.

the name Bingdao is the most expensive in the area and is also the most frequent object of price speculation and counterfeiting.

the age of the trees (táidì is passed off as gǔshù), the season (autumn or summer leaf as spring chunjian), the micro-area (neighbouring villages as Bingdao).
