Rìzhào Lú Chá

Rìzhào Lú Chá (日照绿茶, Rìzhào lǜchá) — green tea from Rizhao city in Shandong Province, one of the northernmost green teas of China and a “new star” (中国绿茶新贵, “green aristocracy of the new generation”) in the world of Chinese tea. Together with Japanese Shizuoka and Korean Boseong, Rizhao forms the trio of the world’s “coastal green teas” (世界三大海岸绿茶). The uniqueness of this tea lies in its northern origin: tea bushes transplanted from the south in 1959 as part of the grandiose state project “Southern Tea to the North” (南茶北引, Nánchá Běiyǐn) were hardened by harsh winters and developed a chemical profile unattainable for their southern counterparts: catechin content 13.7% higher and amino acid content 5.3% higher than teas from traditional southern provinces.

1. Classification and Origin:

• Type: Green tea (non-oxidized). Produced in two forms: curled (卷曲形, juǎnqū xíng) and flat (扁平形, biǎnpíng xíng). By technology — pan-firing combined with baking (炒烘结合).

• Category: National Geographical Indication Product (中国国家地理标志产品, 2006). In 2020, included in the European Union geographical indications registry — one of the first Chinese green teas to receive EU protection. Brand value exceeds 6 billion yuan.

• Origin: China, Shāndōng Province (山东, Shāndōng), Rìzhào City (日照市, Rìzhào Shì). The geographical indication zone covers Donggang District (东港区), Lanshan District (岚山区), Jù County (莒县) and Wulian County (五莲县). Geographic coordinates of the zone: 118°25′—119°39′ E, 35°04′—36°04′ N — this is the northernmost major zone of industrial tea cultivation in China.

• Terroir core: Lanshan District, Jufeng Township (巨峰镇) — the “Tea Capital” of Rizhao. Here is located the famous “Hundred-Li Tea Corridor” (百里茶廊, bǎilǐ chá láng), as well as Jiazishan Mountains (甲子山) and Beiduoshan Mountains (北垛山). Average elevation of tea gardens — 370 m.

2. History and Cultural Significance:

• History: Unlike most famous Chinese teas whose history stretches back centuries, Rizhao Lu Cha is a young tea, born from a state decision. In 1956, the PRC government launched the large-scale project “Southern Tea to the North” (南茶北引, Nánchá Běiyǐn), aimed at expanding tea plantations beyond the traditional “tea belt” of southern provinces. In 1959, Rizhao was chosen as one of the first experimental bases for “northern introduction.”

  The first years were heroic: southern tea bushes died from frost, diseases, and pests. But agronomists through trial and error selected frost-resistant varieties and developed winter covering technology. By 1966, the introduction was recognized as successful.

  Then came rapid growth: from 2 villages and 8.7 mu (0.58 ha) of tea gardens to 333 villages and 10,189 mu (679 ha) by 1998. In 1973, the Ministry of Agriculture of the PRC held a national conference in Rizhao on experience exchange for “Southern Tea to the North,” which became recognition of success at the state level.

  In 1998, tea was approved as a “pillar industry” (支柱产业) of Rizhao’s economy. In 2006 — geographical indication protection. In 2020 — inclusion in the EU geographical indications registry, which opened the path to the European market. The brand value of “Rizhao Lu Cha” exceeded 6 billion yuan.

• Name:

  • “Rizhao” (日照) — “Sunlight” — name of the city on the Yellow Sea coast in Shandong Province. The city is famous for abundant sunny days (average annual sunshine duration — about 14 hours per day in summer).
  • “Lu Cha” (绿茶) — “green tea.”

• Cultural significance: Rizhao Lu Cha is a symbol of the “Southern Tea to the North” project, one of the most successful agronomic experiments in PRC history. The tea embodies the idea of overcoming natural limitations: what was considered impossible (growing tea at the 35th parallel, 5–8° north of traditional tea regions) became reality through determination and scientific approach. For Rizhao city, tea became the economic foundation and cultural brand.

3. Botanical Description and Raw Material:

• Variety / Cultivar: Several frost-resistant varieties of Camellia sinensis var. sinensis are grown in Rizhao, selected during decades of introduction:

  • Huángshān Quntichong (黄山群体种) — local adaptation of Anhui populations, the foundation of Rizhao tea cultivation.
  • Longjing 43 (龙井43) — early clonal variety producing uniform, elegant leaves.
  • Fúdǐng Dàbáichá (福鼎大白茶) — large-leaf Fujian variety with abundant down.
  • Jiūkēng Zhongxiaoyezhong (鸠坑中小叶种) — small- and medium-leaf Zhejiang cultivars with high frost resistance.

  Key feature — all cultivars underwent harsh natural selection: those that couldn’t withstand Shandong winters (temperatures down to –15°C) were eliminated. Surviving populations are distinguished by exceptional frost resistance and ability to accumulate increased amounts of amino acids and catechins due to the extended winter dormancy period.

• Harvest: Three seasons:

  • Spring tea (春茶, chūnchá): Harvest around Gǔyǔ (谷雨, ~April 20) — later than in southern provinces due to later start of vegetation. Standard — one bud with one leaf in initial opening stage. Leaves thick and fleshy. Chestnut aroma — rich. Brewing endurance — maximum. Premium grade (特级) — from 800 yuan per jin.
  • Summer tea (夏茶, xiàchá): Coarser leaves, taste with light astringency, lower endurance.
  • Autumn tea (秋茶, qiūchá): “Autumn White Dew” (秋白露, qiū báilù) — high aroma, rich taste, special character.

• Harvest standard: Three grades:

  • Tèjí (特级): Full buds or one bud with one leaf. Down covers ≥90% of surface. Delicate chestnut aroma, fresh and brisk taste.
  • Yījí (一级): One bud with one leaf. Uniform shoots, clean aroma, soft taste.
  • Èrjí (二级): With admixture of one bud and two leaves. Clean aroma, mellow taste.

4. Terroir and Cultivation:

• Climate: Temperate humid monsoon climate (暖温带湿润季风气候) — fundamentally different from the subtropical climate of traditional tea regions. Key difference — extended winter dormancy period: tea bushes “sleep” 1–2 months longer than in the south, allowing them to accumulate significantly more nutrients before spring awakening. Average annual sunshine duration — about 2540 hours (significantly higher than in mountainous tea regions of the south). Daily temperature fluctuations — large.

• Growing elevation: 100–400 meters above sea level — significantly lower than most famous green teas. Compensation — northern latitude, long winter, and maritime climate.

• Soils: Hilly weakly acidic yellow-brown soils (黄棕壤, huáng zōng rǎng), rich in organic matter and minerals. Forest coverage — 93% — one of the highest among tea-growing zones. Industrial pollution — absent.

• Maritime factor: Rizhao is located on the Yellow Sea coast. Sea breezes bring moisture and moderate temperature fluctuations, creating a unique “coastal” microclimate different from continental mountain terroirs.

• Chemical effect of “northern hardening”: Long winter dormancy + large diurnal temperature range + high insolation = tea leaves with catechin content 13.7% higher and amino acids 5.3% higher than southern analogs. This is a scientifically confirmed fact, repeatedly documented in agronomic research.

5. Production Technology:

Rizhao Lu Cha technology combines manual and mechanized techniques. Two types of shaping are produced: curled (卷曲形) and flat (扁平形).

• Spreading and withering (摊青 — tān qīng): 4–6 hours of spreading in a cool room.

• Kill-green / Fixation (杀青 — shāqīng): At 140–200°C — stopping oxidation. For summer tea, the technique “tender leaf — harsh kill-green” (嫩叶老杀, nènyè lǎoshā) is applied — higher temperature compensates for coarseness of raw material and reduces bitterness.

• Rolling (揉捻 — róuniǎn): Formation of initial structure.

• Secondary pan-firing (二青 — èrqīng): Intermediate drying and aroma development.

• Shaping (做形 — zuòxíng):

  • For curled form — rolling into spirals and bringing out down (搓团提毫, cuō tuán tí háo): master manually forms tight curls while simultaneously “drawing out” silvery down — to the state of “white down like snow” (白毫似雪).
  • For flat form — pressing (压扁, yā biǎn): shaping into flat, smooth tea leaves resembling Long Jing.

• Drying (烘干 — hōnggān): Baking at moderate temperature.

• Aroma enhancement (提香 — tíxiāng): Final brief heating to fix the chestnut aroma.

6. Organoleptic Characteristics:

• Dry leaf appearance: Curled form — thin, tightly curled spirals (条索细紧卷曲), covered with silvery down. Flat form — smooth, uniform, flat tea leaves. Color — emerald green with oily luster. Leaves noticeably thicker and fleshier than southern teas — result of slow growth in cold climate.

• Dry leaf aroma: Rich chestnut aroma (栗香浓郁, lì xiāng nóngyù) — signature note of Rizhao. Complemented by green bean notes (豆香, dòuxiāng) and clean green freshness (清香). Aroma more “dense” and “warm” than southern green teas.

• Liquor aroma: Chestnut dominance, persistent and deep. Delicate green overtones.

• Taste: Mellow and rich (醇厚, chúnhòu), fresh and brisk (鲜爽, xiānshuǎng), with pronounced returning sweetness (回甘持久, huígān chíjiǔ). “Body” — noticeably fuller and more viscous than typical southern green teas: result of increased amino acid and catechin content. Astringency — moderate, without harshness. Aftertaste — long, warm, chestnut-sweet.

• Liquor color: Yellow-green, bright and clear (黄绿明亮).

• Spent leaves: Fleshy, thick, uniform shoots of tender green color (肥厚嫩绿匀整). Leaves noticeably denser than southern analogs.

7. Chemical Composition:

Extended winter dormancy and northern climate create a unique “enhanced” chemical profile:

• Polyphenols (catechins): Content — significantly above average. According to comparative studies, catechin content (儿茶素) in Rizhao Lu Cha is 13.7% higher than in similar green teas from southern provinces. This provides powerful antioxidant potential — free radical neutralization capacity 10 times higher than vitamin E.

• Amino acids (including L-theanine): Content — 5.3% higher than southern teas. Long winter dormancy allows roots to accumulate more nitrogenous compounds, which transform into amino acids at the start of vegetation. Result — more pronounced freshness and sweetness.

• Alkaloids: Caffeine — significant content. Theobromine, theophylline.

• Vitamins: Increased vitamin C content — result of intensive insolation (2540 hours per year).

• Minerals: Fluorine — about 200 ppm (significant for dental enamel protection). Potassium, magnesium, zinc, manganese.

8. Health Properties:

• Powerful antioxidant action: Increased catechin content provides enhanced free radical neutralization — effectiveness 10 times higher than vitamin E.

• Weight control and lipid profile: Catechins suppress fat synthesis with increased effectiveness.

• Dental and vision protection (坚齿明目): High fluorine content (200 ppm) strengthens enamel; vitamin C and carotenoids support eye health.

• Tonic effect: Caffeine combined with L-theanine provides gentle, sustained alertness.

• Digestive improvement: Polyphenols stimulate fat breakdown.

• Immune strengthening: Vitamin-mineral complex supports immune function.

• Important: listed properties are based on publicly available data and are not medical recommendations.

9. Brewing:

• Water temperature: 80–85°C for spring tea; up to 90°C for summer and autumn (coarser raw material withstands higher temperature).

• Tea amount: 3 g per 150 ml water (1:50 ratio).

• Teaware: Glass tumbler or white porcelain gaiwan.

• Process:

  1. Warm teaware with hot water, drain.
  2. Add tea.
  3. First infusion — 30 seconds.
  4. Subsequent infusions — increase time by 10 seconds. Tea withstands 4–8 full brewings — significantly more than typical southern green tea (3–4). Increased endurance — direct consequence of “northern” chemical profile.

• Note: Freshly purchased tea is recommended to rest 15 days in a dark place for “fire taste dissipation” (褪火气). Not recommended to pour boiling water — this destroys chlorophyll and gives yellow liquor.

10. Storage:

• Store in airtight container, in dark, dry and cool place.
• Optimal temperature — 0–5°C (refrigerator), in airtight packaging.
• Storage period — up to 12–18 months.
• After opening — consume within 1–2 months.

11. Price and Counterfeits:

Rizhao Lu Cha is a tea with growing popularity and developed counterfeit infrastructure. Spring tea of premium grade — significantly more expensive than summer and autumn. Main price factors: season (spring > autumn > summer), grade, origin from core zone (Lanshan, Jufeng), manual or machine processing.

• How to avoid counterfeits:

  • Buy from verified sellers with geographical indication marking from Rizhao city.
  • Evaluate leaf thickness: authentic Rizhao — noticeably thicker and fleshier than southern teas. Thin, “papery” leaf — reason for doubt.
  • Evaluate aroma: signature chestnut tone — dense, “warm,” without harshness. Absence of chestnut note — sign of substitution with southern tea.
  • Check endurance: authentic Rizhao withstands 4–8 infusions. “Exhaustion” after 2–3 — probable counterfeit.
  • Pay attention to price: suspiciously low price for spring tea — sure sign of counterfeit.

12. Interesting Facts:

• Rizhao Lu Cha is tea literally “created” by state decision: the “Southern Tea to the North” project of 1956 — one of the most ambitious agronomic experiments in PRC history. Tea bushes transplanted from Anhui, Zhejiang and Fujian 1000 km north repeatedly died from frost before surviving populations adapted.

• Rizhao, Shizuoka (Japan) and Boseong (South Korea) — three world “coastal tea capitals,” located approximately at the same latitude (34–35° N) and united by the influence of warm ocean currents.

• Catechin content 13.7% higher and amino acids 5.3% higher than southern analogs — this is not marketing, but the result of years of comparative agronomic research, due to the objective factor of extended winter dormancy.

• In 2020, Rizhao Lu Cha entered the European Union geographical indications registry — this is one of the first Chinese green teas with European brand protection, alongside Long Jing.

• Forest coverage of the production zone — 93% — one of the highest indicators among tea-growing regions worldwide.

13. Comparison with Other Northern-Type Green Teas:

• Láoshān Lù Chá (崂山绿茶): From Qingdao, Shandong Province. Also “northern” tea, also result of “Southern Tea to the North.” Laoshan — more mineral, with “maritime” note; Rizhao — more chestnut and mellow, with more developed production infrastructure.

• Xìnyáng Máo Jiān (信阳毛尖): From Henan. Also “northern” green tea, but with longer history (2000+ years). Xinyang — more needle-like, with pronounced chestnut aroma of “double wok”; Rizhao — fleshier and “thicker” in leaf texture.

• Xī Hú Long Jǐng (西湖龙井): From Zhejiang. Flat southern tea — lighter, more delicate and beany. Rizhao — significantly more mellow and chestnut, with “heavier” body and better brewing endurance.

• Japanese Shizuoka (静岡): “Neighbor” at the thirty-fifth parallel. Japanese teas — steamed (蒸青), with pronounced “umami” and maritime note. Rizhao — pan-fired (炒青), with chestnut aroma. Different schools — common latitude.

In Conclusion:

Rizhao Lu Cha is a paradox tea, a triumph tea. Born not by nature but by human will, transplanted a thousand kilometers from its homeland and hardened by Shandong winters, it not only survived — it became stronger than its southern ancestors. Increased catechin and amino acid content, dense chestnut aroma, fleshy leaves and endurance for multiple brewings — all these are “gifts” of the harsh north, unavailable to teas from the greenhouse conditions of the south. If Long Jing is a refined aristocrat and Biluochun a fragile beauty, then Rizhao is a strong, enduring warrior with a warm heart: behind the chestnut density of the first sip hides a long, gentle sweetness that returns again and again — to the eighth infusion and beyond.
