lóngshén chá

Lóngshén chá (龙神茶) and Bìkǒu Lóngjǐng (碧口龙井) are related green teas from southern Gansu, from the banks of the White Dragon River (白龙江, Báilóngjiāng). This is the westernmost point of the large tea belt north of the Yangtze (江北, Jiāngběi), where tea culture relies on introduced cultivars and narrow river micro-valleys.

1. Classification and Origin:

• Type: green tea (绿茶, lǜchá).
• Category: míngyōu — “premium quality”; by market positioning 口粮–中, tea of the “everyday-mid” category — a solid local product, not a premium export brand.
• Origin: Lǒngnán (陇南, Lǒngnán) mountainous prefecture in the south of Gansu Province, on the very border with Sichuan and Shaanxi. Tea gardens are concentrated around the town of Bìkǒu (碧口, Bìkǒu) and in valleys carved by the White Dragon River (白龙江, Báilóngjiāng).
• Zone: the extreme western edge of the Jiāngběi zone (江北, Jiāngběi) — the westernmost point of the large tea belt north of the Yangtze, beyond which tea no longer ripens.
• Two names — two forms: Bìkǒu Lóngjǐng (碧口龙井) — flat, “Lóngjǐng-style” processing; Lóngshén chá (龙神茶) — twisted, strip-style processing.

2. History and Cultural Significance:

Tea growing in southern Gansu is a relatively young phenomenon, a fruit of the introduction of culture to the north in the 20th century, and in this sense, Bìkǒu stands alongside the “new” teas of Shandong and Shaanxi. But geographically, it is a special phenomenon: Lǒngnán is the only truly tea-growing corner of the entire Gansu Province, a climatic anomalous “tongue” of the humid south stretching along the White Dragon River.

This river itself is a water and cultural artery of the region: its valleys have served as a corridor between the Sichuan basin and the northwest since ancient times. The development of tea in Bìkǒu relies on this connection — proximity to Sichuan and Shaanxi tea traditions, from which both cultivars and processing techniques, including Lóngjǐng-style pan-firing, have come. For Gansu itself, local tea is a matter of regional pride: proof that even in the arid northwest, there is its own patch of green gardens.

3. Botanical Description and Raw Material:

The raw material is harvested as míngqián (明前), i. e., before the Qingming Festival, which corresponds to the míngyōu segment — “premium quality.” Early harvest means a small, tender bud and leaf, developed over a long, cold spring. Slow growth on the cold edge concentrates the flavor and gives a dense, rich leaf — a typical feature of teas from the northern boundary.

4. Terroir and Growing Features:

From the point of view of tea geography, this is an exceptional case. Gansu is a province of the arid northwest, associated more with the steppe and the Silk Road than with tea terraces. But the southern corner of Lǒngnán lies in the orographic shadow of ridges, where the climate changes sharply: moist air rising from the Sichuan basin operates here, summer is warm and rainy, and the mountains provide an elevation gradient and constant mist. That is precisely why Bìkǒu and neighboring valleys form an isolated “green oasis” — the extreme western edge of the Jiāngběi zone, beyond which tea no longer ripens.

The terroir here is defined by three factors: the river gorges of the White Dragon River with their diffused light and high humidity; medium altitudes with cool nights, slowing bud growth; and acidic mountain soils on the slopes. Together, this provides raw material with a dense, rich leaf — a typical feature of teas from the northern boundary, where slow growth concentrates the flavor.

• Cultivar: in source classification, Lóngshén / Bìkǒu Lóngjǐng belongs to the 引种 (yǐnzhǒng) category — “introduced”, meaning grown from imported cultivars, not from an ancient local population. This makes Gansu tea akin to most northern “new” tea regions — Shandong, the northern counties of Shaanxi — where industrial tea growing was established in the 20th century by transferring cultivars from the south.
• In the gardens of Lǒngnán, introduced clonal plantings coexist with 群体种 (qúntǐ zhǒng) — mixed seedling populations that have gradually adapted to local conditions. It is this adaptation — years of selection of plants that survived the cold winters and late spring frosts of the western edge — that gives the tea a character distinct from the southern “mother” cultivars.

5. Production Technology:

Lóngshén and Bìkǒu Lóngjǐng are classic green teas (绿茶, lǜchá): oxidation is suppressed at an early stage to preserve the freshness of the leaf and the green profile of the infusion. The raw material is harvested as míngqián (明前), before the Qingming Festival.

The leaf shape in these teas is dual — 条/扁形 (tiáo / biǎn xíng), strip or flat. This is the key to understanding the two names:

• Bìkǒu Lóngjǐng (碧口龙井) — flat, “Lóngjǐng-style” processing. The leaf is pressed and smoothed in a heated wok, giving it a smooth, flattened shape modeled after the famous Zhejiang Lóngjǐng. The name directly refers to this style: “Lóngjǐng from Bìkǒu”.
• Lóngshén chá (龙神茶) — twisted, strip-style processing, where the leaf retains an elongated shape.

Both lines undergo the basic green tea chain: withering / spreading → fixation (杀青, shāqīng) → shaping → drying. In the flat version, shaping and fixation are largely combined in manual or mechanical pan-firing; in the strip version, the leaf is first rolled, then finished. The difference in final shape with a shared green profile is a common practice in regions that adopted prestigious southern styles: local masters adopted the Lóngjǐng technique, giving the tea a recognizable name.

6. Organoleptic Characteristics:

The profile is defined by the logic of the northern edge: the slow-growing, dense leaf yields an infusion more saturated and “thick” in body than the soft southern early-spring teas provide. From a Jiāngběi green tea, the following is expected:

• a clear, transparent-greenish or yellow-green infusion;
• a fresh, slightly astringent taste with a noticeable body;
• a green-nutty, “chestnut” tone, typical for northern greens, developed through wok fixation;
• a soft, returning aftertaste.

The flat version (Bìkǒu Lóngjǐng) is closer in presentation to the Lóngjǐng canon — a dryish, toasty note and a smooth leaf; the strip version (Lóngshén) yields a slightly more full-bodied, twisted infusion.

9. Brewing:

Brewing recommendations are standard for a delicate green tea:

• water at 80–85 °C, by no means boiling, otherwise the tender bud will “cook” and produce bitterness;
• light dosage, about 3 g per 150 ml;
• a glass cup or gàiwǎn to see the “dance” of the buds;
• for the most delicate míngqián raw material, the “top-dropping” method (上投法, shàngtóu fǎ) is suitable — the leaves are dropped into the already poured water;
• 2–3 short infusions, observing how the leaf unfolds.

11. Price and Counterfeits:

Lóngshén / Bìkǒu Lóngjǐng is a regional tea of local significance, and a dedicated national GB/T standard under this specific name has not been recorded in the source materials. As a green tea, it falls under the general green tea regulations of the PRC governing classification by grade and harvest season, but attributing a separate standard number to it without confirmation would be incorrect. By market positioning, this is 口粮–中 — tea of the “everyday-mid” category: a solid local product, not a premium export brand.

Several guidelines to avoid confusing Gansu tea with its neighbors along the Jiāngběi edge:

• Origin. Authentic Lóngshén / Bìkǒu Lóngjǐng is from Lǒngnán prefecture in southern Gansu, from the banks of the White Dragon River. This is the western fringe of the entire Jiāngběi zone; there is no “ancient tea district” here — the cultivars are introduced.
• Two forms under two names. If you have a flat, smoothed leaf “in the style of Lóngjǐng” — it is most likely Bìkǒu Lóngjǐng; if it is twisted and strip-like — Lóngshén chá. The green tea profile is shared by both.
• Body of the infusion. Unlike soft southern early-spring teas, the northern leaf yields a denser, more saturated taste with noticeable body and a chestnut tone — a trace of slow growth on the cold edge.
• Do not confuse with benchmarks. Bìkǒu Lóngjǐng is a stylistic processing “in the manner of Lóngjǐng,” not the Zhejiang Xīhú Lóngjǐng; it should not claim the status and price of the latter. It is an honest regional tea of the everyday-mid category.
• Realistic expectations. Lóngshén / Bìkǒu Lóngjǐng is valuable primarily as a geographical curiosity and a solid local green tea — the westernmost outpost of the large Jiāngběi belt — rather than as a premium collectible product.

12. Interesting Facts:

• Bìkǒu and neighboring valleys form an isolated “green oasis” — a climatic anomalous “tongue” of the humid south stretching along the White Dragon River into arid northwestern Gansu.
• Lǒngnán is the only truly tea-growing corner of the entire Gansu Province.
• The valleys of the White Dragon River have served as a corridor between the Sichuan basin and the northwest since ancient times; it was by this route that both cultivars and processing techniques, including Lóngjǐng-style pan-firing, came to Bìkǒu.
