Yóuxī Lú Chá · new.thetea.app

Yóuxī Lú Chá is a regional Fújiàn green tea produced in Yóuxī County (尤溪县, Yóuxī Xiàn) of Sanming Prefecture in Fujian Province. It belongs to the category of hōngqīng lucha (烘青绿茶, hōngqīng lǜchá) — green teas dried with hot air. The product has been protected by geographical indication (地理标志集体商标) since 2010. The calling card of Youxi Lu Cha is the so-called “three greens” (三绿, sān lǜ): emerald-green dry leaves, jade-green liquor, and tender-green spent leaves. Youxi County is among the “Ten Leading Ecological Tea-Producing Counties of China” (全国十大生态产茶县), and the local green tea has earned the unofficial title “First Green of Eastern China” (华东第一绿, Huádōng Dì Yī Lǜ) thanks to the earliest harvest time in the entire Huadong tea region.

2. History and Cultural Significance:

History:

The tea tradition of Yóuxī County traces its roots to the Tāng era (唐, 618–907). In the treatise “The Classic of Tea” (《茶经》, Chá Jīng) by Lù Yǔ (陆羽, Lù Yǔ), compiled around 760–780, in the section “Eight Places Where Tea Is Born” (八之出), teas from Fúzhōu (福州) and Jiànzhōu (建州) are mentioned — territories that included the lands of present-day Youxi. Local chronicles report that tea from Jiànzhōu district (剑州), which included Youxi, was distinguished by high quality and was often presented to the court as tribute tea (贡茶, gòngchá).

During the Míng era (明, 1368–1644), the county chronicle “Youxi County Gazetteer” (《尤溪县志》), dated to the Jiajing reign (嘉靖, 1522–1566), records a tea tax of 25 ingots, evidencing a mature tea industry. During the Qīng era (清, 1644–1912), under Emperor Qiánlóng (乾隆), the county chronicle notes the best teas from the 20th and 23rd districts, with annual production reaching 115 tons. After the opening of the “five ports” (五口通商), tea from Yóuxī was exported to Southeast Asian countries (南洋, Nányáng).

Modern history: in 2010, “Youxi Lu Cha” tea received protected collective trademark status with geographical indication. In 2018, the county entered the “Hundred Strongest Tea Counties of China” (全国茶业百强县). By 2024, the area of tea plantations reached 102,000 mu (approximately 6,800 hectares), annual production volume — 16,800 tons, and the value of the entire tea industry chain reached 1.8 billion yuan. Products are exported to EU countries and Southeast Asia.

Name:

尤溪 (Yóuxī) — toponym, literally “special stream”: 尤 (yóu) — “special, outstanding”, 溪 (xī) — “mountain stream, creek”. 绿茶 (lǜchá) — “green tea”. The full name thus means “green tea from Youxi”.

Cultural significance:

Youxi Lu Cha is the pride and calling card of the county. The tea industry is system-forming for the local economy: the county has formed a complete chain from plantation to export. Taixi Township (台溪乡) has been recognized as a “National Township with Rural Specialized Product Output Exceeding 1 Billion Yuan” (全国乡村特色产业产值超10亿元镇) due to tea production. The early spring harvest is a real event: Yóuxī teas appear on the market by the Lantern Festival (元宵节, Yuánxiāo Jié), ahead of green teas from Zhejiang and Jiangsu by almost two months.

3. Botanical Description and Raw Material:

Variety / Cultivar:

Several main varieties of tea bush (Camellia sinensis var. sinensis) are cultivated in the county:

— Fuyun 6-hao (福云6号, Fúyún Liù Hào) — super-early variety (特早芽种, tè zǎo yá zhǒng). Belongs to medium-leaf shrub forms (灌木中叶种). Possesses good cold resistance. Ideally suited for making flat teas (扁形茶). It is precisely this variety that ensures record-early spring harvest times.

— Fu’an Dàbái (福安大白, Fú’ān Dàbái) — medium-ripening variety, distinguished by abundant down (毫, háo) on buds. Used for producing needle-shaped teas (针形茶).

— Jīn Guānyīn (金观音, Jīn Guānyīn) — also registered as “Mingke 1-hao” (茗科1号). This is a breeding hybrid, originally intended for oolong production, but successfully adapted in Youxi for green tea. Imparts pronounced orchid notes (兰香, lán xiāng) to the product. Used for rolled teas (卷曲形茶).

The coverage rate of improved varieties (良种覆盖率) is 93%. The content of tea polyphenols in spring leaves is not less than 18.3%, with high amino acid content.

Harvest:

Main harvest — spring (春茶, chūnchá), from mid-February (in favorable years — by the Lantern Festival) to April. For highest grades, harvest before the Qīngmíng festival (明前茶, míng qián chá).

Harvest standard:

Regulated by standard T/CSTEA 00043-2022. Special grade (特级, tèjí): single bud (单芽, dān yá) or bud with one beginning-to-unfold leaf (一芽一叶初展), length no more than 3 cm. First grade (一级, yī jí): bud with one leaf (一芽一叶), length no more than 3.5 cm. Second grade (二级, èr jí): bud with two beginning-to-unfold leaves (一芽二叶初展), length no more than 4 cm.

Raw material requirements: The “five prohibitions on picking” rule applies (五不采, wǔ bù cǎi): do not pick in rain, do not pick leaves with dew, do not pick purple shoots, do not pick damaged or diseased leaves, do not pick non-standard raw material. A green plant protection system is applied (诱虫黄板 + 生物农药), chemical fertilizers and pesticides are completely prohibited. All products undergo 100% control for pesticide residues.

4. Terroir and Cultivation Features:

Youxi County is located in the central part of Fujian Province, at the junction of the Dàiyún (戴云山脉, Dàiyún Shānmài) and Wǔyí (武夷山脉, Wǔyí Shānmài) mountain ranges. This creates unique conditions for tea cultivation.

Growing altitude: 300–1,000 m above sea level.
Climate: Subtropical monsoon. Average annual temperature 18.9°C. Annual precipitation — approximately 1,570 mm. Foggy days — more than 180 per year. Daily temperature difference — over 10°C. The proportion of diffused light reaches 70%, which extends the tea bush vegetation period and promotes amino acid accumulation in leaves.
Soils: Acidic red and yellow soils predominate (酸性红壤、黄壤) with fertile horizon depth over 1 m and rich organic matter content. pH level — 4.5–6.0, which is optimal for tea bushes.
Ecology: Forest coverage of the territory — 78.48%. Industrial pollution is absent. Thanks to high biodiversity, natural biological protection from pests ensures a 60% reduction in their population.

Key feature: early spring warming allows tea harvesting to begin earlier than anywhere else in the Huadong region — as early as mid-February. The prolonged cold period in winter and early spring promotes intensive accumulation of free amino acids, ensuring pronounced fresh taste (鲜爽, xiānshuǎng).

Production core: Taixi Township (台溪乡) — 38,000 mu of tea plantations (37% of county area); Banmian (坂面镇) and Tangchuan (汤川乡) townships.

5. Production Technology:

Youxi Lu Cha is produced using classic green tea technology with the main fixation method — drum firing (滚筒杀青, gǔntǒng shāqīng), followed by shaping and air drying. Part of the assortment (炒青类) undergoes wok firing. A characteristic feature is the combination of manual shaping (for rolled teas — up to 14 operations) with mechanized stages.

Fresh leaf picking (采摘, cǎi zhāi): Manual picking according to the “five prohibitions” standard. For highest grades — single buds or bud with one leaf, picked before Qingming.
Enzyme fixation / “kill-green” (杀青, shāqīng): Conducted in a horizontal drum at 240–260°C. Goal — rapid inactivation of polyphenol oxidase and fixation of leaf green color (锁翠, suǒ cuì — “seal the emerald”).
Rolling (揉捻, róuniǎn): Light short-duration pressure (轻压短揉, qīng yā duǎn róu). Task — destroy cellular structure for extraction during brewing, but preserve leaf form integrity. For rolled teas, manual shaping is performed (手工搓揉, shǒugōng cuōróu) — giving leaves spiral form; this process can include up to 14 separate operations.
Breaking up clumps (解块, jiě kuài): Separating leaves that stuck together after rolling.
Drying (烘干, hōnggān): With hot air at 110–120°C to moisture content no more than 6.5%. For chaoqing assortment — the final stage includes wok firing.

Varieties by form and technology:

According to standard T/CSTEA 00042-2022, Youxi Lu Cha is divided into two main groups:

Hōngqīng (烘青, hot air drying): — Yóuxī Máofēng (尤溪毛峰) — loose fluffy leaf; — Yóuxī Juǎnqū (尤溪卷曲/螺形) — spiral-rolled; representative — “Yunfu Xueya” (云富雪芽); — Yóuxī Duoxing (尤溪朵形) — bud-shaped; — Yóuxī Bianzhen (尤溪扁针) — flat needle.

Chǎoqīng (炒青, pan-firing): — Yóuxī Bianchaoqing (尤溪扁炒青) — flat fired; representative — “Penglai Yinluo” (蓬莱银螺); — Yóuxī Yuanchaoqing (尤溪圆炒青) — round fired; — Yóuxī Changchaoqing (尤溪长炒青) — long fired; representative — “Qipin Yipin” (七香一品, needle-shaped).

6. Organoleptic Characteristics:

Dry leaf appearance: Depends on form: flat teas (扁形) — even, straight, emerald-green; needle-shaped (针形) — thin, straight, with abundant white down (白毫, bái háo); rolled (卷曲形) — tightly curled like spirals, dark green with silvery sheen from down. Common trait — uniformity, cleanliness, absence of coarse stems.
Dry leaf aroma: Clean, fresh, with distinct grassy-floral note. Flat teas display chestnut (栗香, lì xiāng) and bean tones. Rolled teas from Jìn Guānyīn cultivar are distinguished by pronounced orchid aroma (兰香, lán xiāng).
Liquor aroma: High and persistent. Main tone — fresh greenness (清香, qīngxiāng); in highest grades — delicate floral nuances. With aging, honey notes may appear (蜜香, mì xiāng).
Taste: Fresh and clean (鲜爽, xiānshuǎng), full-bodied (醇厚, chúnhòu), with prolonged returning sweetness (回甘, huígān). Amino acid richness imparts pronounced umami-like note. Taste holds well for 4–5 infusions and more.
Liquor color: Bright green (碧绿, bìlǜ), clean and transparent, with lively luster. For flat fired teas — yellow-green, light and clean.
Spent leaves (wet leaves): Tender green, uniform, with lively luster (嫩绿匀亮, nèn lǜ yún liàng). Leaves and buds look fresh, “alive,” as if still on the branch. Leaf form when opened resembles orchid flower (芽叶鲜活如兰).

7. Chemical Composition:

Youxi Lu Cha is distinguished by elevated content of biologically active substances, which is related to high-mountain terroir, significant day-night temperature differences, and early spring harvest.

Polyphenols (茶多酚, chá duōfēn): Content in finished tea reaches 37.04% — notably higher than the average indicator for green teas (usually 20–30%). Main component — catechins (儿茶素, ér chá sù), primarily epigallocatechin-3-gallate (EGCG). High polyphenol content provides powerful antioxidant potential.
Amino acids (氨基酸, ānjī suān): Total content is elevated thanks to the prolonged winter period and abundance of diffused light. L-theanine (L-茶氨酸, L-chá ānjī suān) predominates — an amino acid characteristic of tea, responsible for umami note and possessing relaxing action. High amino acid to polyphenol ratio ensures fresh, harmonious taste.
Alkaloids: Caffeine (咖啡碱, kāfēi jiǎn) — typical for green tea content of about 2–4% of dry mass. Theobromine (可可碱) and theophylline (茶碱) are also present in trace amounts.
Vitamins: Vitamin C (ascorbic acid) — content substantially higher than in red teas, thanks to minimal oxidation. B-group vitamins (B₁, B₂), vitamin E (tocopherols), vitamin K are present.
Minerals: Fluorine (氟, fú) — significant content, providing protective action on tooth enamel. Potassium, magnesium, zinc, manganese, selenium are also present.
Essential oils: Aromatic compounds are represented by several hundred components — alcohols, aldehydes, esters. For varieties based on Jin Guanyin, linalool and geraniol are characteristic, determining the floral note.
Unique compositional features: Anomalously high percentage of polyphenols (37.04%) with simultaneously high amino acid content — a rare combination, as these indicators are usually inversely related. This is explained by specific microclimate: diffused light slows the conversion of amino acids to catechins, while high daytime temperatures stimulate polyphenol synthesis.

8. Health Properties:

Powerful antioxidant action: Thanks to 37.04% polyphenol content, free radical neutralization effectiveness is estimated 40% higher than average green tea. EGCG is one of the most studied natural antioxidants.
Blood lipid reduction: Catechins promote regulation of cholesterol synthesis in the liver, reducing levels of “bad” LDL cholesterol. Studies show that green tea can reduce blood lipid content 25% more effectively than red tea, due to preservation of native catechins.
Blood sugar regulation: EGCG inhibits amylase and glucosidase activity, slowing glucose absorption and preventing sharp blood sugar spikes after meals.
Tooth enamel protection: High fluorine content combined with polyphenols forms a protective fluorapatite layer on tooth surfaces, increasing caries resistance. Antibacterial action of polyphenols additionally suppresses cariogenic microorganism activity.
Tonic and nootropic effect: The combination of caffeine and L-theanine provides gentle, prolonged tone without nervousness. L-theanine stimulates α-wave generation in the brain, improving concentration and memory.
Digestive support: Polyphenols stimulate peristalsis and possess antibacterial action against pathogenic GI tract microflora.
Immune strengthening: L-theanine increases γδ-T-cell activity, enhancing innate immune response.
Skin condition support: Antioxidants slow photoaging and help neutralize UV exposure effects.

9. Brewing:

Water temperature: 80–85°C (for special grade from single buds — acceptable to reduce to 75°C). Boiling water is contraindicated: temperature above 85°C destroys theanine and intensifies bitterness.
Tea amount: 3 g per 150 ml (1:50 ratio). When brewing in gaiwan — 5 g per 100–120 ml.
Vessels: Glass tumbler (玻璃杯, bōli bēi) — ideal for observing the “green tea dance” (绿茶舞): opening of buds and leaves in water. White porcelain gàiwǎn (白瓷盖碗, bái cí gàiwǎn) — for aroma evaluation and full extraction control.
Process:

Warm vessel with hot water, drain.
Add tea. For needle-shaped and flat teas, the top-pouring method is recommended (上投法, shàng tóu fǎ): water first, then tea. For rolled — middle-pouring method (中投法, zhōng tóu fǎ): pour ⅓ volume, gently swirl to release aroma (摇香, yáo xiāng), then fill.
Rinsing not required — delicate raw material opens from the first infusion.
First infusion — 30 seconds.
Increase each subsequent infusion by 15–20 seconds.
Repeat brewings — 3–5 times (rolled forms withstand up to 4–5 infusions, flat — 3–4 infusions).

Water: Soft water with low mineralization is recommended — it best reveals sweetness and aroma delicacy.

10. Storage:

Conditions: Airtight, light-proof packaging. Optimally — refrigerator at 0–5°C. Categorically avoid contact with foreign odors, moisture, and direct sunlight.
Containers: Vacuum foil bags, tin cans with tight lids, or specialized tea bags with closures.
Storage period: Most expressive in the first 6–12 months after production. After opening packaging, recommended to consume within 1–3 months, store in refrigerator in hermetically sealed container.
Tea enemies: Light (accelerates chlorophyll and catechin oxidation), moisture (provokes mold), elevated temperature (accelerates aroma loss), foreign odors (tea actively absorbs odors).
Note: New tea is recommended to “breathe” (醒茶, xǐng chá) in a shaded place for 5–7 days before consumption to remove so-called “fire” (火气, huǒqì) acquired during drying.

11. Price and Counterfeits:

Price category: Youxi Lu Cha belongs to the medium price category among Chinese green teas. Cost varies depending on grade and form: special grade (明前茶) from single buds — from 800 yuan/jin (500 g) and higher; first grade — 400–600 yuan/jin; second grade — 150–300 yuan/jin. Price is influenced by harvest season, cultivar, manual or machine shaping.
How to avoid counterfeits:

— Purchase from verified sellers: Give preference to products with geographical indication marking “尤溪绿茶” and collective trademark logo. Better to purchase from known local producers or certified distributors.

— Appearance evaluation: Authentic Youxi Lu Cha is distinguished by even, uniform leaf form, rich green color, absence of coarse petioles and broken leaves. For spiral teas — tight, firm curl; for needle-shaped — even straight form with abundant down.

— Aroma evaluation: Clean, fresh, without rancid, sour, or musty tones. Chestnut or floral shade — sign of quality. Dull, inexpressive smell indicates old or improperly stored raw material.

— Liquor check: Transparent, bright green (or yellow-green for fired types), without turbidity. Cloudy or brownish liquor indicates technology violation or prolonged storage.

— Price check: Suspiciously low cost (less than 100 yuan/jin for allegedly special grade) — serious reason to doubt authenticity.

12. Interesting Facts:

“First Green of Eastern China”: Youxi Lu Cha is the earliest green tea of the Huadong tea region. Spring harvest begins by the Lantern Festival (mid-February), ahead of famous teas from Zhejiang and Jiangsu by almost two months. The reason — early spring warming in the mountain basin between Daiyun and Wuyi ridges combined with the super-early Fuyun 6-hao cultivar.
Oolong cultivar in green tea: Jīn Guānyīn (金观音), bred as a variety for oolongs, is successfully used in Youxi for green tea production. This imparts an orchid note unusual for green teas to part of the assortment, making it more akin to light oolongs than classic lucha.
14 manual operations: Rolled spiral teas (“Yunfu Xueya” and analogs) are shaped manually in 14 sequential stages — one of the most labor-intensive technologies among Fujian green teas.
Polyphenol record holder: Tea polyphenol content up to 37% — a rare indicator for green tea, usually characteristic rather of summer harvest large-leaf Assam cultivars. In Youxi’s case, this is achieved through terroir while simultaneously maintaining high amino acid content — a paradoxical combination determining unique taste balance.
EU export: Youxi Lu Cha is one of the few Chinese regional green teas that have passed European organic certification. 100% of products undergo pesticide residue testing, and the “green protection” system (生物防控) completely excludes chemical application on plantations.

Youxi Lu Cha stands out among Fujian green teas with unique multi-form nature (three basic forms in one designation), record-early spring harvest, and use of oolong cultivar Jin Guanyin. Unlike Anji Bai Cha with its low polyphenols and theanine accent, Youxi Lu Cha demonstrates anomalously high polyphenol levels with good amino acid content — a powerful, rich tea, not a delicate “watercolor.”

In Conclusion

Youxi Lu Cha is a tea discovery for those accustomed to the “big three” Chinese green teas and seeking something new. It combines classic Fujian tea culture with intensity uncharacteristic of green teas: powerful polyphenol profile, rich amino acid framework, and as a bonus, the possibility of encountering orchid notes in green tea usually associated with oolongs. The earliest spring tea of Eastern China, appearing on the market by the Lantern Festival — an excellent choice for those not ready to wait for Qingming and wanting to start the tea season with a sip of fresh, “still winter” spring.
