Pǔ'ān gǔshù lǜ

A green tea from the southwestern corner of Guizhou that reaches the market earlier than almost any other tea in China and relies on the unique gene pool of old tea trees — Pǔ’ān gǔshù lǜ (普安古树绿) connects two themes: “antiquity of origin” and “the earliest harvest.”

1. Classification and Origin:

• Type: green (unfermented) tea.
• Category: belongs to the category of Chinese green teas and, like any green tea, follows the general rules of this class regarding raw material, technology, and the absence of fermentation.
• Origin: Pu’an County (普安县) in the Qianxinan Buyi and Miao Autonomous Prefecture (黔西南) in the west of Guizhou Province. A mountain region of the Yunnan-Guizhou Plateau.
• Standard: it would be incorrect to cite a specific “named” national GB/T number for this regional style — the direction is positioned primarily through its geographical origin (Pu’an, Guizhou) and raw material characteristics (old trees, early harvest), rather than through a widely known product standard of the famous “Ten Teas” level.
• Segment: mid-to-high — it is not a mass-market “rice” product, but neither is it a handcrafted collector’s item.

It is important to distinguish the segments within a single name: “gushu” (古树, from old trees) and “early” (早茶) are two intersecting but non-identical emphases. The first stresses the origin of the raw material, the second — the calendar early ripening.

2. History and Cultural Significance:

The cultural strength of Pu’an lies in the depth of the district’s tea history. The status of “the land of ancient tea trees” (古茶树之乡) rests on the ancient tea gene pool and old-growth stands preserved here; it is this connection with the “roots” of the tea plant that shapes the local identity and brand.

The second pillar is early ripening. In China’s tea calendar, Pu’an acts as one of the very first suppliers of spring green tea: “early tea” (早茶) here is not a marketing label, but a real competitive advantage, when the first batches emerge on the market while the classic eastern terroirs are only just waking up. This “early tea” is the county’s economic and reputational trump card, placing it alongside such early centers as Yibin in Sichuan. For the local economy, the combination of “ancient and early” has become the foundation of a recognizable profile.

3. Botanical Description and Raw Material:

Pu’an Gushu Lü is based on two related sources of raw material:

• sìqiú gǔchá (四球古茶) — the local ancient tea material, which gave its name to the whole direction and reflects the old, “wild” in origin, gene pool of the area.
• Local populations (群体种) — traditional seed-grown plantings, genetically heterogeneous and well-adapted to local conditions.

Such raw material is valued specifically for its non-standardization: leaves from old trees and seed populations yield a deeper, richer infusion and complex aroma, unlike the even but “flatter” profile of clones.

4. Terroir and Cultivation Features:

• Landscape: the mountain region of the Yunnan-Guizhou Plateau, with the characteristic combination for southern Guizhou of low latitudes, significant altitude, frequent fogs, and diffused light — classic conditions for the slow, aromatic growth of the tea leaf.
• Gene pool: Pu’an’s key feature is its reputation as “the land of ancient tea trees” (古茶树之乡). An ancient tea gene pool is preserved here, and it is precisely the reliance on old-aged trees and local populations that distinguishes this tea from the lowland plantation lines of neighboring Guizhou areas.
• Phenology: thanks to the mild winter and early warmth, Pu’an is considered one of the earliest tea districts in China — the first spring harvest here begins earlier than in most recognized green terroirs.

5. Production Technology:

By shape, Pu’an Gushu Lü is a strip-style (条形) green tea: leaves twisted into longitudinal “threads,” rather than flat plates or rolled balls, typical of some other Guizhou styles.

Processing follows a green (unfermented) scheme with two possible finishing paths:

• Pan-frying (炒青, chǎoqīng) — fixation and drying in a heated wok/drum, yielding a more “burnt-chestnut,” dense aromatic profile.
• Baking/drying (烘青, hōngqīng) — a softer, “fresh-green,” and floral-herbaceous profile.

The general logic of green tea is preserved: early harvest of tender raw material, mandatory green fixation (杀青, shāqīng) to stop oxidation, shaping into strip form by rolling, and drying to completion. The combination of pan-frying and/or baking allows the producer to balance between “fried” depth and “fresh” lightness.

Since the raw material includes leaves from old trees and seed populations, it requires careful work: such leaves are less homogeneous than clonal ones, and quality strongly depends on manual sorting and precise temperature control during fixation.

6. Organoleptic Characteristics:

The profile of Pu’an Gushu Lü is defined by the combination of an early tender harvest and an “ancient” gene pool:

• Dry leaf — strip-style, dark green.
• Infusion — fresh and clean, with a herbaceous-floral top note in baked versions and a more pronounced chestnut-fried note in pan-fried ones.
• Body: due to the old tree raw material, the body of the infusion feels somewhat denser and more stable than that of light plantation green teas from the same region.

9. Brewing:

Brewing recommendations are standard for a high-quality green tea:

• Water — about 80 – 85 °C, not boiling, so as not to “burn” the tender early leaf.
• Vessel — a glass cup or gaiwan, allowing observation of the strip-style leaf unfurling.
• Proportions — approximately 3 g per 150 ml.
• First infusion — short; the early, tender material “gives up” its qualities readily even on the first pours.

10. Storage:

As with all green teas, the main value is freshness: Pu’an Gushu Lü should be drunk young, within the current season, stored in an airtight container away from light, heat, and extraneous odors.

11. Price and Counterfeits:

To avoid confusing Pu’an Gushu Lü with neighboring Guizhou green teas, it is worth relying on several characteristics:

• Shape. Pu’an is a strip-style (条形) tea. This distinguishes it from the flat, smooth leaf of Meitan Cuiya (湄潭翠芽), from the thinly twisted “fish hooks” of Duyun Maojian (都匀毛尖), and even more from the pressed “balls” of Leishan Yinqiu (雷山银球茶).
• Raw Material Origin. The emphasis on “gushu” (from old trees) and local populations, as well as the mention of sìqiú gǔchá (四球古茶) — is a marker of Pu’an.
• Season. The emphatically stated early ripening (“the earliest in spring”) is a signature trait; batches appear on the market very early.
• Profile. In contrast to the “zinc-selenium” positioning of Fenggang (凤冈锌硒茶) or the albino “white” leaf of Zheng’an Baicha (正安白茶), Pu’an is sold through the idea of an ancient gene pool and a dense, fresh infusion.

The combination of “strip shape + old/seed raw material + ultra-early harvest + origin from Pu’an (黔西南)” is the reliable signature of this tea.
