Zhèjiāng sōngzhēn

Zhejiang “Song Zhen” (“Pine Needles”) is a green tea from Chun’an County (淳安) in Zhejiang Province, located on the shores of the famous Thousand Island Lake (千岛湖, Qiāndǎo Hú). The main distinctive feature of this tea is the combination of a hybrid cultivar based on Camellia sinensis var. assamica — atypical for Zhejiang — with classical Zhejiang pan-firing technology and meticulous hand-shaping of “pine needles.” The result is a tea with pronounced umami, chestnut notes, and creamy texture, noticeably different from familiar Zhejiang green teas (Longjing, Anji Bai Cha) in both raw material and flavor profile.

1. Classification and Origin:

• Type: Green tea (unfermented, oxidation level <5%). Fixation method — pan-firing (炒青, chǎoqīng).
• Category: Chinese premium green tea of needle shape (松针形绿茶, sōngzhēnxíng lǜchá).
• Origin: China, Zhèjiāng Province (浙江, Zhèjiāng), Chun’an County (淳安县, Chún’ān Xiàn), Thousand Island Lake region.
• Geographic coordinates: Approximately 29°30′ North latitude, 118°55′ East longitude. Plantation altitude — 800–1200 meters above sea level.

2. History and Cultural Significance:

• History:

Chun’an County is one of China’s most ancient tea regions with a tea cultivation history spanning nearly 2000 years. In ancient times, this area was called Muizhou (睦州) or Qīngxī (青溪), and already during the Tang era (7th–10th centuries) was one of the recognized “tribute zones” (贡茶区, gòngchá qū), supplying tea to the imperial court. The great Tāng tea treatise writer Lù Yǔ (陆羽) in “The Classic of Tea” (茶经) mentioned tea from Muizhou alongside the finest teas of the era. In “Supplements to the National History of Tang” (唐国史补) it is recorded: “常州有宜兴之紫笋, 婺州有东白, 睦洲有鸠坑” — “In Changzhou there is Zisun from Yixing, in Wuzhou — Dongbai, in Muizhou — Jiukeng.”

Chun’an is precisely the birthplace of the famous Jiūkēng cultivar (鸠坑种, Jiūkēng zhǒng) — the only “seed-propagated” (有性系, yǒuxìngxì) tea variety in Zhejiang. Jiukeng is one of the most widely distributed tea varieties in the world: it was successfully introduced to Japan, the Soviet Union, India, Vietnam, and more than ten other countries. In 2003, Jiukeng seeds were sent to space aboard “Shenzhou-5” (神舟五号) for a space breeding experiment.

The modern tea “Song Zhen” (Pine Needles) from Chun’an is a relatively recent development, most likely emerging in the second half of the 20th century as part of a program to diversify the region’s tea production. Unlike the famous local tea Qiandao Yüye (千岛玉叶, “Jade Leaf of Thousand Islands”), created in 1982 in Longjing style, “Song Zhen” took a different path: instead of flat “blade” shape — long straight needles; instead of small-leaf var. sinensis cultivar — a hybrid based on var. assamica. This is a conscious experiment: bringing “Yunnan power” to refined Zhejiang terroir.

• Name: “Song” (松) — pine; “Zhen” (针) — needle. The name precisely describes the appearance of tea leaves — long, flat, straight, pointed, resembling pine needles. The “pine needle” shape (松针形) is one of several classical “figured” forms of Chinese green tea, alongside “sparrow tongues” (雀舌形), “spirals” (螺形), “blades” (扁形), and “pearls” (珠形).

• Cultural significance: Chun’an “Song Zhen” is symbolically connected to the mountain pine forests of the Qiandaohu area — one of the largest forest massifs in Eastern China (national forest park, over 634 plant species). The tea’s shape refers to this natural environment: tea needles — like pine needles on the lake shores. For the Chun’an region, traditionally associated with Jiukeng and Qiandao Yüye, “Song Zhen” represents an innovative direction — an attempt to expand the palette of Zhejiang tea production beyond familiar flat and twisted shapes.

3. Botanical Description and Raw Material:

• Variety / Cultivar: Hybrid Camellia sinensis var. assamica × Chǎng Yè Bái Háo (长叶白毫, Chángyè Báiháo) — “Long-leaf White Down.” This is an atypical choice for Zhejiang Province: the vast majority of Zhejiang green teas (Longjing, Anji Bai Cha, Jiukeng Mao Jian, Jingshan) are produced from small-leaf var. sinensis cultivars. Using an assamica hybrid brings several fundamental differences:
  • Larger leaves with higher chlorophyll content (more intense green color).
  • Higher polyphenol (catechin) content — a characteristic feature of assamica.
  • Denser, more “fleshy” leaf blade, allowing formation of long needles without brittleness.
  • Potentially higher L-theanine content (under conditions of shading or high-altitude slow growth).
• Picking: For this specific tea, whole young leaves are used, including summer harvest (third flush, 三水茶). For highest grades — spring harvest (春茶). Standard — bud and one-two top leaves.
• Raw material requirements: Young, undamaged leaves of specific size (sufficiently long for needle formation) are selected. Uniformity of length and thickness is a key requirement.

4. Terroir and Cultivation Features:

• Region: Chun’an County (淳安县) in the western part of Zhejiang Province. Located on the shores of Thousand Island Lake (千岛湖) — the largest artificial freshwater body in Eastern China, formed by the Xin’anjiang River dam (新安江) in 1959. The lake with more than 1078 islands creates a unique microclimate: the huge water mass moderates temperature fluctuations and maintains high humidity.
• Growing altitude: 800–1200 meters above sea level — significantly higher than Xi Hu Longjing (200–400 m) or Anji Bai Cha (300–600 m).
• Soils: Predominantly acidic (pH 4.5–5.5), iron-rich (红壤/黄壤, red/yellow soils). Elevated iron content may influence the tea’s mineral profile. Good natural drainage from mountain topography.
• Climate: Temperate subtropical, with high humidity (influence of lake waters), average annual temperature around +18°C, abundant precipitation. Mountain topography provides frequent fogs and natural diffusion of sunlight.
• Special features: Possible application of natural or partial shading (遮阴, zhēyīn), promoting increased L-theanine and chlorophyll content. Proximity to pine forests of Qiandaohu National Park creates a clean ecological environment (absence of industrial pollution, high level of phytoncides).

5. Production Technology:

The technology is based on the classical Zhejiang pan-firing method (炒青), but with special emphasis on the “needle” shaping stage.

• Withering (摊凉, tānliáng): Brief withering (4–8 hours) to reduce leaf moisture and provide elasticity necessary for subsequent shaping. Moisture loss — about 15–20%.

• Kill-green (杀青, shāqīng): Pan-firing in a heated wok (锅炒, guōchǎo) at high temperature (~180–200°C) for rapid enzyme inactivation. Classical Zhejiang method, analogous to Longjing production.

• Rolling (揉捻, róuniǎn): Light rolling to extract cell juices and prepare for shaping. Delicate — to avoid damaging long leaves.

• Shaping / Pressing (理条/做形, lǐtiáo/zuòxíng): Key and most labor-intensive stage, determining the character of “Song Zhen.” Leaves are repeatedly pressed and straightened — by hand or with special tools — to achieve the characteristic flat, straight, needle-like shape. Each leaf is stretched longitudinally and pointed, requiring high skill: tea leaves must be thin, even, 20–25 mm long, without cracks or breaks. This stage distinguishes “Song Zhen” from most other green teas: shaping “needles” is significantly more complex than rolling spirals (Bi Luo Chun) or pressing “blades” (Longjing).

• Drying (烘干, hōnggān): Final drying with hot air to reduce moisture to <5%, fix shape and stabilize aroma.

• Sorting (分级, fēnjí): Finished tea is sorted by length, uniformity and integrity of “needles.” Broken and uneven needles are sifted out.

6. Organoleptic Characteristics:

• Dry leaf appearance: Long (20–25 mm), flat, straight tea leaves of silvery-green color, resembling pine needles. Whole, even, without breaks. Smooth surface with light luster.
• Dry leaf aroma: Fresh, grassy, with light notes of seaweed and freshly cut grass. Subtle “coniferous” coolness — associative, more due to shape and context than literal presence of terpenes.
• Liquor aroma: Delicate, fresh, grassy-floral, with distinct chestnut overtone (栗香, lìxiāng) — characteristic note of Zhejiang pan-fired green teas.
• Taste: Smooth, soft, sweetish, with pronounced umami (旨味) — deep, “brothy” taste due to high L-theanine content. Notes of raw chestnut, hazelnut, fresh greens. Creamy texture (奶滑, nǎihuá). Aftertaste — long, sweetish, with light minerality.
• Liquor color: Clear, light green with yellowish tint (黄绿明亮, huánglǜ míngliàng).
• Spent leaves (wet leaves): Bright green, whole, elongated leaves maintaining needle-like shape. Larger than typical Zhejiang teas — heritage of assamica cultivar.

7. Chemical Composition:

• Polyphenols (catechins): High content, with EGCG dominance. The assamica hybrid provides potentially higher catechin levels than small-leaf var. sinensis Zhejiang cultivars.
• Amino acids: Elevated L-theanine content (responsible for umami and sweetness). High-altitude slow maturation and possible shading promote amino acid accumulation.
• Alkaloids: Caffeine — provides mild, sustained tonic effect. Synergy with L-theanine creates “calm alertness” without anxiety.
• Chlorophyll: Elevated content (assamica cultivar + possible shading) — ensures intense green color of dry leaf and liquor.
• Vitamins: Vitamin C, B-group vitamins.
• Minerals: Fluorine, potassium, manganese. Iron from soils may be present in trace amounts, contributing to the mineral character of aftertaste.

8. Health Properties:

• Antioxidant protection: High EGCG and other catechin content (potentially higher than var. sinensis from the same region) provides powerful free radical neutralization.
• Cognitive function improvement: Pronounced L-theanine and caffeine synergy promotes relaxed concentration — a state of “calm alertness” that enhances productivity without nervous excitement.
• Oral health: Fluorine and antibacterial properties of catechins suppress growth of cariogenic bacteria.
• Metabolic support: Catechins and caffeine contribute to accelerated metabolism and thermogenesis.
• Relaxing effect: L-theanine contributes to anxiety reduction, improved sleep quality with daytime consumption.

9. Brewing:

• Water temperature: 75–85°C. Range wider than for steamed teas (70°C), but below boiling. Pan-fired Zhejiang teas are more temperature-resistant, however overheating still causes bitterness.
• Tea amount: 3–5 g per 150–200 ml water. For flash steeping method — 4–5 g per 150 ml.
• Teaware: Glass or porcelain gaiwan, glass teapot. Glass is especially recommended for “Song Zhen”: observing the unfolding of long “needles” is a separate aesthetic pleasure. Yixing clay not recommended: it absorbs delicate aromas.
• Process (flash steeping method, 功夫泡法):
  1. Warm teaware with hot water.
  2. Add dry tea, inhale aroma.
  3. First steeping — 30–60 seconds at 80°C.
  4. Second steeping — 20–30 seconds (flavor intensifies).
  5. Third and subsequent — 30–45–60 seconds with gradual increase.
  6. Tea withstands 4–5 full steepings.
• Alternative method (glass tumbler, 杯泡法): 3 g per 250 ml at 80°C, steeping 3–4 minutes. Ideal for daily tea drinking and contemplating the “dance of needles.”

10. Storage:

Store in airtight, opaque packaging (foil bag, tin can) in a dry, cool place, away from strong odors. Optimally — in refrigerator at 0–5°C in reliably sealed container. At room temperature — not above +25°C. Recommended storage period — up to 18 months; maximum freshness — in first 6–9 months. Summer harvest (third flush) is less sensitive to aging than spring, but also loses aroma brightness over time.

11. Price and Counterfeits:

Price varies depending on harvest season and grade. Spring harvest (春茶) — 20–35 USD per 100 g (retail); summer harvest (夏茶 / 三水茶) — 10–18 USD per 100 g — more affordable alternative.

• How to avoid counterfeits:
  • Check appearance: authentic “Song Zhen” — even, whole, straight needles 20–25 mm long, silvery-green color. Large amount of broken pieces, uneven or too short tea leaves — sign of low quality or substitution.
  • Evaluate aroma: should be fresh, grassy-chestnut, without “smoky,” “burnt,” or artificial odors.
  • Test taste: at 80°C — pronounced umami, sweetness, creamy texture, without harsh bitterness. Absence of umami — possible sign of substitution with cheaper raw material (var. sinensis instead of assamica hybrid).
  • Purchase from suppliers specializing in Zhejiang teas and able to confirm origin (Chun’an / Qiandaohu).

12. Interesting Facts:

• Chun’an County is the birthplace of Jiūkēng cultivar (鸠坑种), which remains the only “seed-propagated” (reproduced by seeds, not cuttings) tea variety in Zhejiang. The ancient “Jiukeng Tea Tree King” (鸠坑茶树王, “King of Jiukeng Tea Trees”) 4.2 meters tall with a crown diameter of more than 30 m² still grows in Tanglian village, Jiukeng township.
• In 2003, Jiukeng seeds were sent to space aboard China’s first manned spacecraft “Shenzhou-5” for a space breeding experiment (航天育种, hángtiān yùzhǒng), attracting worldwide attention.
• Thousand Island Lake (千岛湖) is an artificial reservoir formed in 1959 during construction of the Xin’anjiang dam. Its creation flooded two ancient cities (遂安 and 淳安) and transformed the region’s ecology. Today the lake is one of Eastern China’s largest freshwater reservoirs with Class I water purity (国家一级水体), providing exceptional ecological environment for tea plantations.
• Using var. assamica hybrid for green tea in Zhejiang is a conscious break with tradition: for centuries the province specialized exclusively in small-leaf var. sinensis. “Song Zhen” is one of few Zhejiang teas demonstrating that large-leaf raw material can produce interesting results in this terroir.
• The “pine needle” shape (松针形) also exists in red tea — the famous Yúnnán Diān Hóng Sōng Zhèn (滇红松针) from large-leaf Yunnan Da Ye Zhong variety. Zhejiang green “Song Zhen” is a kind of “green response” to Yunnan: same shape, different tea type, different terroir.
• The neighboring Zhèjiāng tea from Wǔyí County (武义) — “Wuyang Chunyu” (武阳春雨, “Spring Rain of Wuyang”) — is also described as “形似松针丝雨” (“shaped like pine needles and rain threads”), indicating a broader Zhejiang tradition of needle-shaped green teas.

13. Comparison with Other Green Teas:

• Xī Hú Lóngjǐng (西湖龙井, Xīhú Lóngjǐng): Zhejiang’s most famous tea. Flat “blade” shape, var. sinensis cultivar (Longjing 43, Quntitzhong). Aroma — nutty-pumpkin (豆花香, “bean flower aroma”), “roasted.” Taste — clean, refreshing, with characteristic “bean” sweetness. “Song Zhen” — heavier in “body,” with more pronounced umami and creamy texture; less “light” and “transparent” than Longjing.
• Ānjí Bái Chá (安吉白茶, Ānjí Báichá): Unique “white-leaf” green tea from albino cultivar Bái Yè Yī Háo (白叶一号). Aroma — orchid, floral. Taste — maximally “amino acid”: umami dominates, bitterness practically absent. “Song Zhen” is closer to Anji Bai Cha in umami expression, but differs in chestnut notes and denser “body” (assamica influence).
• Diān Hóng Sōng Zhèn (滇红松针): Yunnan red tea in the same “pine needle” shape. Cultivar — Yunnan Da Ye Zhong (var. assamica). Taste — honey-chocolate, rich, sweet. Green “Song Zhen” — fresh, grassy, with umami; they share shape and “large-leaf DNA” of assamica, but processing type creates diametrically opposite flavor profiles.
• Jiūkēng Máo Jiān (鸠坑毛尖): Classic tea from the same Chun’an County, but from local Jiukeng cultivar (var. sinensis). Small, straight, downy needles. Aroma — persistent, clean. Taste — dense, with characteristic Chun’an minerality. “Song Zhen” — larger, softer, with more pronounced umami and creamy texture; Jiukeng Mao Jian — stricter, “drier,” more classical.

14. Possible Contraindications:

• Individual intolerance or allergic reactions.
• Due to caffeine content — caution with increased nervous excitability, insomnia, hypertension during acute periods.
• Not recommended on empty stomach for people with sensitive stomach: catechins and caffeine stimulate gastric secretion.
• Caution during pregnancy (especially first trimester) and breastfeeding.
• Possible interaction with some medications (anticoagulants, iron preparations); medical consultation recommended.

In Conclusion:

Zhejiang “Song Zhen” is a paradox tea: it is born in a province that for centuries built its tea identity on small-leaf var. sinensis cultivars (Longjing, Anji, Jiukeng) — and consciously breaks this tradition by using an assamica hybrid. It originates from the most ancient tea county (Chun’an with its two-thousand-year history) — but is a modern development. Its “pine needle” shape echoes Yunnan red tea — but it is unquestionably “green,” Zhejiang, pan-fired. This very complexity makes “Song Zhen” interesting for connoisseurs: creamy texture and deep umami from assamica, chestnut note of Zhejiang pan-firing, minerality of iron-rich mountain soils and ecological purity of Thousand Island Lake shores — all this combines into a tea unlike any other green tea of the province.
