ziyang hongcha

botany material

cultivar: The main cultivar is Zǐyáng Zhūyè variety (紫阳槠叶种, Zǐyáng zhūyè zhǒng), a local population of Camellia sinensis var. sinensis, approved in 1965 as one of 21 national elite varieties. Shrub form with early shoot formation, dense branching, high frost resistance and rich biochemical composition of fresh leaves. Characterized by a favorable ratio of polyphenols to amino acids, making it suitable for both green and red tea.

picking: From mid-March to early October. Spring harvest (before Qingming and before Guyu) is most valuable; summer and autumn batches are also processed, including for red tea.

pluck standard: For highest grades of red tea — 1 bud or 1 bud + 1 leaf; for standard batches — 1 bud + 2 leaves and equally tender shoot sections.

raw material: Fresh, whole shoots without mechanical damage; raw material must be processed within 8 hours of harvest; preliminary grading by quality.

brewing

brewing x4: Local tea growers insist that for full acquaintance with Ziyang tea, one must go through at least three brewings: first — light, almost watery; second — revelation of bitterness and aroma; third — full depth of taste with long returning sweetness.

tea amount: 4–5 g per 100–120 ml (gongfu); 2–3 g per 200–250 ml (steeping).

teaware: Porcelain gàiwǎn (盖碗) 100–120 ml or glass vessel (cup) for visual observation of liquor color; Yixing teapot is acceptable, but gaiwan is preferable for revealing pure, high aroma.

water temp: 90–95°C for standard batches; 85–90°C for delicate single-bud grades.

chemistry

alkaloids: Caffeine — about 3–4%; theobromine and theophylline — in trace amounts.

amino acids: 3.08%, maximum — up to 5.69% — this is a high indicator for Chinese tea raw material, explaining the mildness and sweetness of taste.

chemistry x3: In fresh leaves — about 207.3 mg/g total catechins; EGCG — up to 122.86 mg/g in finished first-grade tea.

chemistry x4: Key distinguishing marker. Average content — 0.653 ppm, maximum — up to 3.854 ppm. Selenium is in organic form (predominantly selenomethionine), ensuring high bioavailability. According to the 1989 expert examination, natural selenium tea possesses antioxidant, anti-tumor, anti-radiation effects and the ability to boost immunity.

chemistry x7: The ratio of polyphenols to amino acids (about 10:1 in fresh leaves) is optimal for red tea production: sufficient polyphenol level for color and body formation, while high amino acid background ensures mildness and sweetness, and natural selenium adds functional value unmatched among other red teas.

minerals: Besides selenium, elevated zinc (Zn) content is noted; potassium, magnesium, manganese, fluorine are present.

polyphenols: About 30.35% in fresh leaves (data from Tea Research Institute of Chinese Academy of Agricultural Sciences); with full oxidation, a significant portion converts to theaflavins and thearubigins.

vitamins: C (partially preserved), B₁, B₂, E, P (rutin).

classification origin

category: Shaanxi red tea; part of the umbrella brand "Ziyang Fuxi Cha" (紫阳富硒茶, "Selenium-rich tea from Ziyang"), registered as a geographical indication (地理标志产品, GI) and well-known trademark (中国驰名商标). Historically, Ziyang is primarily a green tea region (famous for Ziyang Maojian and Ziyang Cuifeng), however since the 2000s red tea has occupied a growing niche in the assortment.

coordinates: approximately 32°28′ N, 108°25′ E (center of Ziyang County).

origin: China, Shaanxi Province (陕西省, Shǎnxī Shěng), Ānkāng City (安康市, Ānkāng Shì), Zǐyáng County (紫阳县, Zǐyáng Xiàn). The production zone covers 20 townships and towns: Chengguan, Huangu, Xiangyang, Hongchun, Maoba, Malü, Donghe, Haoping, Wamiao, Gaoqiao, Shuangqiao, Bantao, Huishui, Hanwan, Shuang'an, Dongmu, Bajiao, Miaohe, Guangcheng, Liaoyuan and others.

type: Chinese red tea (红茶, hóngchá), fully oxidized.

comparison

comparison x0: Another Shaanxi red tea, but from the central part of the province; without the selenium advantage, using different cultivars; aroma and body are less pronounced.

comparison x1: Anhui, small-leaf raw material. Similar to Ziyang in terms of raw material type (small-leaf population), but the terroir is fundamentally different — no selenium enrichment; Qihong's aroma is more "orchid-like," while Ziyang is softer and more "silky."

comparison x2: Sichuan, medium-leaf raw material. Characterized by orange-caramel aroma (橘糖香); Ziyang is more delicate, with a floral-honey profile and without the "caramel" brightness.

comparison x3: Hubei, medium-leaf population. Geographically closest to Ziyang; similar "northern" character — softness, sweetness, purity; however, without the selenium factor.

comparison x4: Guangdong, large-leaf raw material. More powerful and "southern" in profile; Ziyang is the antithesis: light, delicate, "northern."

health

health x0: Regular consumption of Ziyang tea is one of the simplest, most accessible and safest ways to obtain organic selenium. According to medical research, selenium deficiency is linked to more than 40 diseases, including cardiovascular, oncological and endocrine conditions.

health x1: Dual antioxidant mechanism — theaflavins/thearubigins (polyphenolic protection) + selenium (cofactor of glutathione peroxidase, a key antioxidant enzyme).

health x2: Selenium participates in immune response regulation; combined with tea polyphenols provides synergistic supportive action on the immune system.

health x3: Caffeine combined with L-theanine provides steady concentration boost without "nervous" peaks; especially valuable for prolonged mental work.

health x4: Red tea with full oxidation is gentle on gastric mucosa; warm infusion after meals promotes comfortable digestion.

health x5: Selenium combined with tea flavonoids supports vascular elasticity and normal blood viscosity.

health x6: The 1989 examination confirmed radioprotective properties of Ziyang Fuxi Cha; relevant for people working in conditions of elevated ionizing or electromagnetic background.

history culture

cultural significance: Ziyang County is a place where several cultural layers intersect: tea culture (贡茶之乡 — "hometown of tribute tea"), Taoist heritage (Ziyang Cave, Leigutai Temple), folk musical tradition (紫阳民歌, "Ziyang folk songs" — object of national intangible heritage), selenium gastronomy. The tea ceremony in Zǐyáng traditionally includes three infusions (三道水) and is considered incomplete without them: the first sip — light, almost bland; the second — bitterness transitioning to aroma; the third — full flavor development with long aftertaste. Numerous teahouses (茶馆) in the county center are a living image of tea life, reminiscent of old Chengdu tea houses. Since 2001, the annual Ziyang Tea Culture Festival has been held, attracting tea lovers from all over China. The region is also an important watershed zone for the "South-to-North Water Diversion Project" (南水北调), which imposes strict ecological restrictions and maintains the purity of the terroir.

history: Ziyang's tea tradition is one of the oldest in China. The territory belonged to the ancient state of Bā (巴国), whose people were already cultivating tea during the Shang-Zhou era (11th–3rd centuries BCE). During the Western Han period (206 BCE – 9 CE), tea trade was established here, and in the Tang era (618–907) tea from southern Shaanxi — "tea from the southern mountain lands" (山南茶, shānnán chá) — was included in the registry of tributes to the imperial court. During the Song and Ming eras, Ziyang became a key link in the tea-horse trade system (茶马互市, chámǎ hùshì) on the northwestern borders of the empire: tea was exchanged for horses with nomads, and the volumes were so large that chronicles note — "tea growers labored day and night, men abandoned the fields, women left their looms." During the Qing era, Zǐyáng Máojiān (紫阳毛尖) entered the ranks of China's Ten Famous Teas. The poetic line "自昔关南春独早，清明已煮紫阳茶" ("Since ancient times spring comes first to the southern slopes — by Qingming they are already brewing tea from Ziyang") became a popular expression in tea culture. In 1915, tea from Ziyang was presented at the Panama-Pacific International Exposition in San Francisco. After the establishment of the PRC, in 1951, Ziyang was included in the state tea production plan. In 1965, the Zǐyáng Zhūyè variety (紫阳槠叶种) was approved by the Ministry of Agriculture as one of 21 national elite tea cultivars. The selenium era began in 1989, when the Shaanxi Scientific Committee conducted an

name breakdown: Zǐyáng (紫阳) — the name of the county, which in turn derives from the Taoist master Zhāng Bóduān (张伯端), known by the honorary name Zǐyáng Zhenren (紫阳真人, "True Man Ziyang"), founder of the Southern School of Taoism (道教南派), who practiced in local mountain caves. Literally "Ziyang" means "purple light from the east, all-pervading radiance" (紫气东来，阳光普照). Ziyang is the only county in China named after a Taoist dedication. Hóng chá (红茶) — "red tea."

organoleptic

dry leaf appearance: Tight, dense twist; leaf compact, dark, with noticeable down (白毫) in highest grades; overall appearance — neat and uniform.

dry leaf aroma: Warm, honey-floral, with the "purity" characteristic of northern teas and a light creamy note; without heavy or smoky undertones. In "floral-fruity type" batches (花果香型) the "perfumed" upper register is pronounced.

liquor aroma: Multi-layered: top notes — wildflowers and honey; middle — ripe stone fruits (apricot, peach); base — bread crust and light caramel. Aroma delicate but persistent.

liquor color: Bright red, clear and brilliant; in highest grades — with pronounced golden rim.

spent leaves: Red-copper, evenly colored; leaves soft, elastic, fully expanded.

taste: Dense and rounded, with pronounced natural sweetness; minimal astringency, quickly transitioning to long, "silky" aftertaste (回甘). Body — medium, without heaviness; "clean" and transparent taste — consequence of high amino acid content and moderate polyphenol levels.

production

production x0: Manual; "ticai" method (提采) — breaking the shoot upward.

production x1: Indoor natural or on withering trays; duration 12–18 hours; leaf moisture reduced to 60–62%. In spring, when temperatures are low, withering proceeds more slowly, which is favorable for aroma.

production x2: Mechanical or manual; 60–90 minutes in 2–3 sessions with intermediate separation of clumps. Goal — destruction of cell walls to release juices and ensure uniform oxidation; rolling degree 80–90%, by the end of the process the leaf emits a pronounced tea aroma.

production x3: In specialized rooms at 25–28°C and high humidity; duration 3–5 hours until formation of red-copper leaf color and characteristic fruity smell. Small-leaf raw material with high amino acid content requires more delicate temperature control to avoid "over-fermentation" and preserve sweetness.

production x4: Two-stage: high-temperature (毛火) to stop oxidation, then low-temperature prolonged (足火) to fix aroma. The technology of "medium-temperature slow drying and low-temperature prolonged drying" (中温慢烘、低温长烘), characteristic of the Ziyang style, is applied.

production x5: Sifting, wind sorting, manual selection, final heating.

terroir

altitude: 350–900 m (main tea garden zone); extremely dissected terrain — mountain ridges, gorges and narrow river valleys; overall altitude range in the county — from 277 to 2,522 m.

climate: Northern subtropical humid monsoon. Average annual temperature — 15.1°C; frost-free period — 268 days; the Qínlǐng Ridge (秦岭) to the north blocks Siberian cold masses, while the Dabashan Mountains (大巴山) to the south retain warm humid air, forming a mild, humid microclimate at the junction of North and South.

soil: Yellow-brown and mountain-yellow soils, acidic to slightly acidic (pH 4.5–6.8). Key feature — natural selenium enrichment: the county is located on an extensive outcrop of selenium-bearing rocks (富硒岩层), selenium content in soil — 5.66–32.06 ppm, making Ziyang one of China's two main "selenium zones." Tea grown on these soils accumulates selenium naturally: average Se content in tea leaves — 0.653 ppm, maximum — up to 3.854 ppm.

terroir x2: about 1,127.8 mm annually; additional moisture comes from the Hàn River (汉江) and Rènhé River (任河) crossing the county.

terroir x4: Ziyang is the northernmost of China's ancient tea regions (北缘古茶区). The northern latitude causes slower accumulation of substances in the leaf and, consequently, increased amino acid content and a more delicate aromatic profile compared to southern analogues. Strict ecological norms (watershed zone for the South-North project) practically exclude the use of chemical protection agents; most plantations meet safety standards equivalent to organic.
