"old trees" (老树, lǎoshù)

most often a compressed cake (饼茶, bǐngchá), frequently of a standard weight of 357 g

Type: raw pu'er (生茶, shēngchá)

Facts

the market concepts of "plantation" (台地), "big trees" (大树, dàshù), "old trees" (老树), and "ancient trees" (古树) are structured by age and growth character but are not standardised and are interpreted differently by sellers.

raw pu'er matures naturally over years, while ripe (熟) pu'er is obtained in weeks by means of wet-piling (渥堆).

the traditional cake format is linked to the historical packaging of "seven cakes" (七子饼, qīzǐbǐng) into one stack-"tong" (筒, tǒng).

it is precisely sun-drying (晒青) that distinguishes raw material for pu'er from other green teas and preserves the ability for further maturation.

the harvest from non-irrigated old trees fluctuates perceptibly from year to year, so that the same tea from different harvests may differ noticeably in character.

History and Culture

Yunnan is considered one of the centres of origin of the tea plant, and the mountainous regions of the southern province are the cradle of large-leaf tea.

the custom of compressing tea into cakes and "bricks" is historically linked to the convenience of transportation along mountain routes.

Botany and Raw Material

tree or semi-tree (乔木, qiáomù / 小乔木, xiǎoqiáomù), in contrast to trimmed bushes on plantations

large, leathery, with pronounced venation and serrated edge

usually a bud with two to three leaves (一芽二叶, yīyá èryè / 一芽三叶, yīyá sānyè)

Cultivar: Camellia sinensis var. assamica, large-leaf variety of the tea plant

Terroir

Climate: subtropical monsoon, with a pronounced division into wet and dry seasons, frequent fogs, and significant diurnal temperature variation

Soil: red-yellow lateritic, well-drained

mountain slopes of Yunnan; the altitude range typical for the Menghai area is approximately 1000–1800 m above sea level

old trees often grow in mixed forest or sparse plantings, with minimal human intervention

Production

hand-picking of young flushes

the leaf is laid out to lose part of its moisture

heating in a wok; performed more gently than for green tea, to partially preserve the enzymes

shaping the leaf and releasing juices

obtaining "maocha" — sun-dried raw material (晒青毛茶, shàiqīng máochá)

moulding into cakes, bricks, or "nests"

slow drying of finished products

Organoleptic Profile

dark green with olive-brown shades, large twisted leaves, often with light buds

young tea — light golden with a greenish hue; with years of storage, it deepens to amber

floral-honey, notes of dried fruit, mountain herbs; young tea has a perceptible "green" freshness, while aged tea develops woody and camphor tones

pronounced returning sweetness (回甘, huígān) and salivation (生津, shēngjīn); good raw material is characterised by a sensation of "tea force" (茶气, cháqì)

Taste: dense, "thick" (厚, hòu) body, initial bitterness (苦, kǔ) and astringency (涩, sè), which transform relatively quickly into sweetness

Chemical Composition

in the large-leaf cultivar the proportion is, as a rule, higher than in small-leaf varieties

the main source of astringency and bitterness

provides the tonic effect

form "umami" and sweetish notes

participate in forming the body of the infusion and its colour

Health Notes

due to caffeine, imparting energy and clarity

linked to the high polyphenol content

in Chinese practice, sheng pu'er is often drunk after heavy or fatty food, associated with a sensation of lightness

Brewing

soft, with low mineral content

for old-tree tea, 95–100 °C; for young and harsh sheng, it can be lowered to about 90 °C to subdue bitterness

roughly 6–8 g per 100–150 ml for the infusion method; for simple brewing in a large volume — less

a short infusion of 5–10 seconds, which is discarded

first steepings are short (about 5–10 seconds), thereafter the time is gradually increased; quality material withstands 10–15 or more infusions

Teaware: gaiwan (盖碗, gàiwǎn) or Yixing teapot (紫砂壶, zǐshāhú); porcelain and gaiwan are more convenient for evaluating aroma and nuances

Storage

Humidity: moderate, approximately 55–70%; excessive dryness retards maturation, excessive humidity leads to mould

a dry, ventilated place free of foreign odours, away from direct light and heat sources

breathable packaging; airtight plastic is not suitable for long-term storage of sheng

"dry warehouse" (干仓, gāncāng) yields a clean, predictable maturation and is preferable to "wet warehouse" (湿仓, shīcāng)

Price and Authenticity

Banghai is a little-known designation, so such tea is usually in the middle price zone and noticeably cheaper than heavily marketed areas such as Laobanzhang (老班章, Lǎobānzhāng), Bingdao (冰岛, Bīngdǎo), or Yiwu (易武, Yìwǔ). The specific price depends greatly on the year, plucking quality, and seller, so it is more correct to view it as a range rather than a fixed figure.

genuine old-tree tea yields a dense infusion, a deep and long return of sweetness, and durability across many infusions; a plantation imitation quickly turns unpleasantly bitter without transformation and "fades" after a few steepings.

large, dense, and elastic leaves with pronounced veins are a good sign; brittle, small, and uniformly chopped leaf is a cause for suspicion.

a suspiciously cheap "old-tree" tea almost certainly is not one.

sellers with a transparent origin of batches and the possibility of tasting the tea before purchase are preferred.
