Yongtai Lü Chá

Yongtai Lü Cha is a regional green tea from Yongtai County, Fujian Province, awarded the status of a product with protected geographical indication (国家农产品地理标志). Its benchmark qualities are succinctly formulated as “high aroma, pure taste, clear liquor, lustrous color” (香高、味醇、汤清、色润). The rich tea cultivation history of this mountainous county traces back to the Tang era, and during the Ming period, local teas were presented to the imperial court as tribute.

2. History and Cultural Significance:

• History:

The tea tradition of Yongtai County spans over a thousand years. Already in the Tāng era (唐代, Táng dài, 618–907), tea production was conducted here: in Lu Yu’s famous treatise “The Classic of Tea” (《茶经》, Chájīng, c. 760–780), the Fuzhou territory is mentioned as a tea region, geographically including the lands of present-day Yongtai.

The flourishing of local tea cultivation occurred during the Míng era (明代, Míng dài, 1368–1644). During the reign under the Hongwu era name (洪武, Hóngwǔ, 1368–1398), “fine tea from Yongfu” (永福细茶, Yǒngfú xìchá) — as the county was then called — was included in the register of imperial tribute (贡品, gòngpǐn). Particular fame was gained by tea from Téngshān (藤山茶, Téngshān chá) and tea from Jīyán Temple (姬岩茶, Jīyán chá).

In the 1980s, Yongtai’s tea cultivation reached industrial scales: the area of tea gardens comprised 25.1% of the entire tea fund of Fuzhou Prefecture, and production volume — 31.5%. The main market was the northern provinces of China.

The newest stage of development was marked by important milestones: in 2015, the Ministry of Agriculture of the PRC granted Yongtai Lü Chá the status of a product with protected geographical indication (国家农产品地理标志). In 2021, Yongtai entered the “Hundred Strongest Tea Counties of China” (中国茶叶百强县), and the value of the entire tea industry’s production in the county reached 1 billion yuan. In 2022, the tea was recognized as a “regional public brand of Fuzhou,” in 2023 — as a “national product with special qualities” (全国名特优新农产品).

• Name:

永泰 (Yǒngtài) — toponym meaning “eternal tranquility / eternal prosperity”; 绿茶 (lǜchá) — “green tea.” Thus, the full name directly indicates the place of origin and category: “green tea from Yongtai.”

• Cultural significance:

Yongtai is historically called the “back garden of Fuzhou” (福州后花园, Fúzhōu hòuhuāyuán) for its picturesque mountain landscapes and clean ecology. Tea culture is organically woven into the local way of life: the principle “tea as offering, tea as ritual” (以茶为礼、以茶生礼) is passed down from generation to generation. Spring tea picking remains a significant seasonal event, and the county’s Yongtai Green Tea Museum introduces visitors to the history and technology of local tea cultivation.

3. Botanical Description and Raw Material:

• Variety / Cultivar: The foundation of plantations (about 70%) consists of cultivars from the Fúyún series (福云系列, Fúyún xìliè) — primarily Fuyun 6-hao (福云6号, Fúyún liù hào) and Fuyun 595 (福云595, Fúyún wǔjiǔwǔ). As supplementary varieties, Longjing 43 (龙井43, Lóngjǐng sìshísān), Tiě Guānyīn (铁观音, Tiěguānyīn) and Jīn Guānyīn (金观音, Jīn Guānyīn) are used. In recent years, new promising varieties have been introduced: Róngchūn Zǎo (榕春早, Róngchūn zǎo) and Ānjí Bái Chá (安吉白茶, Ānjí Báichá). Additionally, the local population Yǒngtài Càichá (永泰菜茶, Yǒngtài càichá) — an indigenous small-leaf tea bush — is preserved. All indicated cultivars belong to the species Camellia sinensis var. sinensis.
• Picking: Main picking — spring (late March — April); summer and autumn picking are also possible. Spring tea (春茶, chūnchá) is most valued due to increased amino acid content.
• Picking standard: Depends on grade: for special grade (特级, tèjí) — individual buds or bud with one leaf (单芽 or 一芽一叶, yī yá yī yè); for first grade (一级, yījí) — bud with two leaves (一芽二叶, yī yá èr yè); for second grade (二级, èrjí) — bud with three leaves (一芽三叶, yī yá sān yè).
• Raw material requirements: Leaves must be fresh, whole, without mechanical damage and signs of disease. Picking is done by hand in morning hours during dry weather.

4. Terroir and Cultivation Features:

• Topography and climate: Yǒngtài County is located on the northeastern slope of the Dàiyún Mountains (戴云山脉, Dàiyún shānmài), in the middle and upper reaches of the Dàzhāng River (大樟溪, Dàzhāng xī) — a tributary of the Min River. The terrain is mountainous, with the local formula “eight parts mountains, one part water, one part fields” (八山一水一分田) reflecting the landscape character: mountain ridges, deep gorges, numerous streams. The climate is subtropical monsoon: average annual temperature 14.6–20.7°C, annual precipitation 1400–2000 mm, number of foggy days over 200 per year. Significant diurnal temperature variation and predominance of diffused light stimulate amino acid accumulation in leaves (spring tea amino acid content ≥ 4.0%).
• Growing altitude: The main part of tea plantations is located at 500 m and higher above sea level. Forest cover of the county — 76.8%.
• Soils: Red soils (红壤, hóng rǎng) predominate with acidic reaction (pH 4.0–5.5), good sandy structure, deep fertile layer and high organic matter content. Notably, 78% of the county’s soils are enriched with selenium (Se content 0.15–0.35 mg/kg), which is a distinctive feature of the local terroir. The water of the Dazhang River meets Class II purity standards. On plantations, an ecological cycle “pig farming — biogas — tea cultivation” (猪-沼-茶) is practiced, excluding the use of chemical fertilizers and pesticides.
• Key subregions:
  • Lufeng Tea Garden in Tong’an Town (同安镇卢峰茶园, Tóng’ān zhèn Lúfēng cháyuán) — demonstration zone for tea agritourism.
  • Ancient tea tree group in Wútóng Town (梧桐镇古茶树群, Wútóng zhèn gǔ cháshù qún) — age of individual specimens up to 2500 years.
  • Jīyán Temple tea zone in Báiyún Township (白云乡姬岩茶区, Báiyún xiāng Jīyán cháqū) — cloud belt at altitude over 500 m.

5. Production Technology:

Yongtai Lü Cha is produced using classical green tea technology with pan-firing as the fixation method (炒青, chǎoqīng). The production cycle includes up to 28 operations and is considered an object of intangible cultural heritage. The distinctive feature is the combination of mechanical and manual processing, using exclusively bamboo and wooden tools to avoid oxidation from contact with metal.

• Picking (采摘, cǎizhāi): Hand picking according to standards corresponding to the target grade. For special grade — about 40,000 buds are required for 500 g of finished tea.
• Withering/spreading (摊放, tānfàng): Freshly picked leaves are spread in a thin layer on bamboo screens for 4–6 hours for partial moisture removal and activation of enzymatic processes that form aroma.
• Fixation — “kill-green” (杀青, shāqīng): Processing in a rotating drum at 200–240°C. High temperature inactivates polyphenol oxidase, preventing oxidation and preserving the green color of the leaf.
• Rolling (揉捻, róuniǎn): Light mechanical rolling for 10–15 minutes under moderate pressure. Breaks down cellular structure, ensuring uniform extraction during brewing.
• Shaping (做形, zuòxíng): Hand rolling into strips (搓条, cuōtiáo) — a stage that forms the characteristic “tight straight strip” shape (紧结匀整). Depending on the substyle, the leaf may take a form from straight to slightly curved.
• Drying (烘干, hōnggān): Gentle drying at 60–80°C to residual moisture of about 5–6%. Fixes the shape and stabilizes the aromatic profile.
• Refining (精制, jīngzhì): Sorting, removal of stems and off-grade material.
• Final heating for aroma enhancement (提香, tíxiāng): Key stage forming the signature chestnut aroma (栗香, lìxiāng) of Yongtai Lü Cha. Requires high-precision control of temperature and time.

6. Organoleptic Characteristics:

• Dry leaf appearance: Tightly twisted, even, straight strips (条索紧结匀整, tiáosuǒ jǐnjié yúnzhěng); color — rich green with light luster and visible white down (色泽绿润毫显, sèzé lǜrùn háo xiǎn). The straight form of the leaf is the “calling card” of the style. Two subtypes are distinguished: straight strip form (直条形, zhítiáo xíng) — such as Songkou Lóngjǐng (嵩口龙井) — and curved strip form (曲条形, qūtiáo xíng) — the classic, most widespread variant.
• Dry leaf aroma: Clean, distinct, with pronounced chestnut notes. Fresh harvest has bright floral overtones.
• Liquor aroma: Chestnut aroma (栗香, lìxiāng) dominates — the main marker of the style. Individual batches have floral and light grassy undertones. The aroma is high, persistent, multi-layered.
• Taste: Fresh, mellow-rich, with distinct sweetness and rounded aftertaste (鲜醇甘爽, xiān chún gān shuǎng). The umami component is perceptible due to high amino acid content. With correct brewing, bitterness and astringency are minimal. The aftertaste includes pronounced returning sweetness (huí gān) (回甘, huígān) and salivation-inducing (shēng jīn) (生津, shēngjīn).
• Liquor color: Tender green, bright, clear (汤色嫩绿明亮, tāngsè nènlǜ míngliàng); in first infusions — with a light yellowish tint.
• Spent leaves (wet leaves): Green, bright, even (叶底绿亮匀齐, yèdǐ lǜ liàng yún qí). Leaves unfold completely, maintaining elasticity and uniform color.

7. Chemical Composition:

• Polyphenols (茶多酚, chá duōfēn): 10–30% (calculated on dry matter), which is typical for green teas. Catechins (especially EGCG) provide antioxidant activity; according to sources, the effectiveness of free radical neutralization is 18 times higher than that of vitamin E. The catechin content in high-mountain tea is somewhat lower than in lowland tea, which reduces bitterness and increases sweetness of the liquor.
• Amino acids (氨基酸, ānjīsuān): Total content 100–220 g/kg (with water hydrolysis), which is significantly higher than the average indicator for green teas. L-theanine (L-茶氨酸, L-cháānjīsuān) is the dominant amino acid, providing characteristic freshness and umami. The high level of amino acids is due to mountain terroir: reduced temperatures and abundance of diffused light slow the conversion of amino acids to polyphenols.
• Alkaloids: Caffeine (咖啡碱, kāfēijiǎn) — 2–4%; theobromine and theophylline in trace amounts. Caffeine content in the upper range for green tea provides pronounced tonic effect.
• Vitamins: Vitamin C (ascorbic acid) is preserved in significant quantity thanks to gentle processing technology. Also present are B-group vitamins (B₁, B₂), vitamin E, β-carotene.
• Minerals: Potassium, manganese, zinc, fluorine. A distinctive feature is increased selenium (Se) content in tea, due to the geochemistry of local soils. Fluorine contributes to strengthening tooth enamel and suppressing cariogenic microflora.
• Essential oils: Responsible for forming the chestnut-floral aromatic profile; their content and composition are determined at the final heating stage (提香).

8. Health Properties:

• Antioxidant action: High content of polyphenols and catechins provides effective neutralization of free radicals, slowing cellular aging processes.
• Tonic effect: Caffeine combined with L-theanine gives a gentle but sustained surge of vigor without sharp excitement — a state of “calm concentration.”
• Lipid metabolism support: Catechins accelerate fat breakdown; according to some data, effectiveness is 30% higher than standard green teas, which may be related to the special ratio of polyphenols and amino acids.
• Oral health: Fluorine contained in leaves suppresses the growth of cariogenic bacteria and reduces dental plaque formation.
• Digestion: Polyphenols gently stimulate GI tract peristalsis, reduce bloating, promote food assimilation.
• Cognitive functions: L-theanine improves concentration and reduces anxiety without causing drowsiness.
• Selenium protection: Due to natural selenium enrichment, regular consumption may contribute to immune support and antioxidant protection at the cellular level.

9. Brewing:

• Water temperature: 80–85°C. Using boiling water (over 90°C) is strongly not recommended — L-theanine is destroyed, freshness is lost, bitterness increases.

• Tea amount: 3 g per 150 ml (1:50 ratio) for glass method; 5–7 g per gaiwan (盖碗, gàiwǎn) 100–120 ml for gongfu.

• Teaware: Glass tumbler (玻璃杯, bōlibēi) — optimal choice: allows observing bud unfolding in water (“dance of tea leaves”). White porcelain gaiwan and small porcelain teapot are also suitable.

• Process (glass method — top-down pouring method):

  1. Warm glass with hot water, drain.
  2. Pour hot water (85°C) to 7/10 of glass volume.
  3. Carefully add tea — leaves will begin to slowly sink and unfold.
  4. Steep for 2–3 minutes, observing the vertical “standing” of buds in the glass.
  5. Drink in small sips; when reduced by 1/3 — add water. 2–3 refills are acceptable.

• Process (gaiwan, gongfu style):

  1. Warm gaiwan and fairness cup with boiling water.
  2. Add 5–7 g tea, lightly shake gaiwan — inhale dry leaf aroma.
  3. First infusion (润茶, rùnchá): 85°C, 5 seconds — discard (rinse).
  4. Second infusion: pour water, hold for 15–20 seconds, pour into cups.
  5. Increase each subsequent infusion by 10 seconds. Yields 4–6 quality infusions.

10. Storage:

• Conditions: Airtight, opaque container (vacuum foil bags, tin cans). Store away from light, moisture, heat sources and foreign odors.
• Temperature: Optimal — refrigerator, 0–5°C. At room temperature, storage life is significantly reduced.
• Shelf life: Tea maintains greatest expressiveness in the first 6–12 months after production. After opening packaging, recommended to consume within 7 days to avoid aroma loss.
• Special note: Freshly made tea is recommended to be aged 7–15 days in a dark place to remove “fire energy” (褪火气, tuì huǒqì) before first tasting.

11. Market and Price Range:

• Price category: Cost depends significantly on grade and picking season:

  • Special grade (特级): from 700 yuan per jin (500 g) and higher — individual buds or bud with one leaf, intense chestnut aroma.
  • First grade (一级): 300–500 yuan per jin — bud with two leaves, clean, fresh taste.
  • Second grade (二级): 100–300 yuan per jin — bud with three leaves, rich, full-bodied liquor. Factors affecting price: picking time (spring > summer > autumn), subregion (high-mountain Baiyun, Hongxing more expensive), certification (organic, green product), producer reputation.

• How to avoid counterfeits:

  • Purchase from producers and sellers with license to use geographical indication “永泰绿茶” and corresponding marking (标识).
  • Evaluate appearance: dry leaf should be even, uniform in size, with distinct down — without yellow, broken or over-dried fragments.
  • Check aroma: quality Yongtai Lü Cha has clean chestnut aroma without mustiness, sourness or mold smell.
  • Evaluate liquor: it should be clear, tender green — cloudy or dark liquor indicates technology violation or staleness.
  • Pay attention to price: suspiciously cheap “Yongtai Lü Cha” special grade (less than 500 yuan per jin) is highly likely to be counterfeit or off-grade.

12. Interesting Facts:

• In Yongtai County, groups of ancient tea trees up to 2500 years old have been discovered — among the oldest in Fujian Province, they are a valuable genetic resource for breeding.
• The production technology includes 28 operations and is recognized as an object of intangible cultural heritage. The entire cycle — from rolling to drying — is performed using bamboo and wooden tools: contact of tea with metal is completely excluded.
• 78% of the county’s soils are naturally enriched with selenium — a rare microelement with antioxidant properties. This makes Yongtai Lü Cha one of the few “selenium” green teas of China.
• During the Ming era, tea from Yongtai (then — Yongfu, 永福) was presented to the imperial court; particular fame was gained by tea from the mountain Jīyán Temple (姬岩) — one of the famous Buddhist monasteries of the region.
• Yongtai County is the first in Fuzhou Prefecture to pass state certification as an “ecological county” (生态县, shēngtài xiàn) in 2014, confirming the clean environment for tea cultivation.

13. Comparison with Other Green Teas:

• Ānxī Huángjīn Guì (安溪黄金桂, Ānxī Huángjīn Guì): Also from Fujian, but belongs to oolongs; similar cultivars (Tie Guanyin, Jin Guanyin), however fundamentally different technology — semi-oxidation. Yongtai Lü Cha, unlike oolongs, emphasizes freshness and chestnut note, not floral/creamy palette.
• Xīhú Lóngjǐng (西湖龙井, Xīhú Lóngjǐng): “Famous tea” of Zhejiang; flat, with pronounced bean aroma and higher amino acid content. Yongtai Lü Cha — in straight/curved strip form, with dominant chestnut note instead of bean; significantly more affordable in price.
• Xìnyáng Máojiān (信阳毛尖, Xìnyáng Máojiān): Green tea from Henan; thin, down-covered needles, fresh and somewhat astringent taste. Yongtai Lü Cha is less astringent, with more pronounced chestnut note and gentle sweetness due to high amino acid content.
• Méngdǐng Gānlù (蒙顶甘露, Méngdǐng Gānlù): Sichuan green tea with curled leaves and bright “sweet dewy” profile. Yongtai Lü Cha has fuller body and chestnut accent, while Ganlu is more delicate and floral.
• Ēnshī Yùlù (恩施玉露, Ēnshī Yùlù): Tea from Hubei, one of the few Chinese “steamed” green teas (蒸青, zhēngqīng). Its profile is grassy-marine, with pronounced umami; Yongtai Lü Cha, produced by pan-firing method, gives more “dry,” chestnut-floral aroma and less grassy taste.

In Conclusion

Yongtai Lü Cha is a green tea with over a thousand years of history, grown from the quiet mountain tradition of Yongtai County into a recognizable regional brand of national scale. Its signature formula — “chestnut aroma with floral undertone, fresh and sweet taste, clear green liquor” — is the direct result of a fortunate combination of high-mountain terroir, selenium soils, ancient cultivars and meticulous handwork in 28 operations. This tea will suit those who value “honest” regional green teas without famous names: for a moderate price, Yongtai Lü Cha offers genuine quality — purity of taste, ecological excellence and living connection with one of the oldest tea-growing regions of Fujian.
