Hezhou Zi Cha is a unique purple-leaf tea from the Guangxi Zhuang Autonomous Region, the signature tea of Hezhou Prefecture. Its distinguishing feature is an exceptionally high content of anthocyanins in young shoots, giving the leaves an intense red-purple coloration year-round. The breeding series “Gui Zi” (桂紫), developed by “Xiaohe Gudao” company (潇贺古道), laid the foundation for forming a new regional brand, which during the restructuring of Hezhou’s tea industry received the unified name “Hezhou Zi Cha” (贺州紫茶), replacing the former designation “Zi Ya Cha” (紫芽茶, “purple bud tea”). The tea sage Lù Yǔ (陆羽) wrote in the “Cha Jing” (茶经): “茶，紫者上” — “among teas, purple is the finest,” and Hezhou Zi Cha perfectly embodies this ancient maxim.

1. Classification and Origin:

Type: Purple-leaf tea (紫叶茶, zǐ yè chá) — a special group of tea products united not by processing method, but by botanical characteristics of the raw material: abnormally high content of anthocyanins (花青素, huāqīngsù) in young plant tissues. Depending on processing technology, it can be produced as green tea (绿茶, lǜchá), red tea (红茶, hóngchá), white tea (白茶, báichá), or dark tea using Liú Bǎo technology (六堡茶, Liùbǎo chá). Green and red versions are most common.
Category: Regional specialty tea of Guǎngxī (广西特色茶). Included in the “桂字号” (Gui Zi Hao — “Guangxi Quality Mark”) brand list of the Department of Agriculture of Guangxi Zhuang Autonomous Region.
Origin: China (中国), Guǎngxī Zhuāng Autonomous Region (广西壮族自治区, Guǎngxī Zhuàngzú Zìzhìqū), Hèzhōu Prefecture (贺州市, Hèzhōu Shì). Main production zones — Bābù District (八步区, Bābù Qū), Píngguì District (平桂区, Píngguì Qū), and Zhāopíng County (昭平县, Zhāopíng Xiàn). “桂紫系列” plantations are concentrated primarily in Babu, from which comes the historically first commercial name “Babu Zi Cha” (八步紫茶).
Geographic coordinates: Approximately 24°24′ N, 111°30′ E (center of Babu District). Plantations are distributed across several elevation zones — from hilly foothills to mountain slopes at 400–800 m elevation.

2. History and Cultural Significance:

History: Tea cultivation in the Hezhou region has centuries-old roots. According to “Song Huiyao Jigao” (宋会要辑稿, “Compilation of Important Documents of the Song Dynasty”), during the Song era, Zhaozhou Prefecture (昭州, now Zhaoping County) supplied 7,500 jin (斤) of tea to the court. During the Tang and Song dynasties, “Wei Guo Qing” tea (未过清) from the Tengbao and Xiangqi mountains in Zhaoping was considered a “tea treasure” (“Zhongguo Mingcha Tupu,” 中国名茶图谱). The tradition of “Kaishan Baimaocha” (开山白毛茶, “white-hair tea from Kaishan Mountain”) from Babu also dates back several centuries. The modern history of Hezhou’s actual “purple tea” begins in the 2010s. The company “Hezhou Shi Xiaohe Gudao Tese Chanye Fazhan You Xian Gongsi” (贺州市潇贺古道特色产业发展有限公司, “Hezhou Xiaohe Gudao Specialty Industry Development Co., Ltd.”), founded by entrepreneur and Chairman of Hèzhōu Tea Association Lǒu Yinglian (楼应莲), isolated and established breeding lines of tea bushes with stable purple coloration of shoots — the “Gui Zi” series (桂紫). Through years of selection, varieties “Gui Zi 1 Hao” (桂紫1号) and “Gui Zi 2 Hao” (桂紫2号) were developed and registered. With the beginning of Hezhou’s tea industry restructuring, “purple” teas were unified under the single regional brand “Hezhou Zi Cha” (贺州紫茶).
Name:
- 贺州 (Hèzhōu) — prefecture in northeastern Guangxi, the historical name dates back to the Tāng era (武德四年, 621 CE), when Hèzhōu (贺州) was established.
- 紫茶 (Zǐchá) — “purple tea,” indicating the characteristic red-purple color of young shoots, caused by high anthocyanin content.
- 八步 (Bābù) — “eight steps,” toponym of Babu District, where the main “Gui Zi” series plantations are located.
- Earlier commercial name — “Xiaohe Gudao Zi Ya Cha” (潇贺古道紫芽茶, “purple bud tea of Xiaohe Gudao”), named after the ancient trade route Xiaohe (潇贺古道), which connected central China with the south.
Cultural significance: Hezhou Zi Cha is positioned as the “signature tea” of the new generation of Guangxi teas, complementing the region’s traditional brands — “Zhaoping Cha” (昭平茶) and Guǎngxī Liú Bǎo Chá (六堡茶). Purple tea occupies a notable place in Hezhou’s tea tourism, and the routes “Xiaohe Gudao — Guxiang Cha Zhi Lü” (潇贺古道—故乡茶之旅, “Journey to Native Tea along Xiaohe Gudao”) were included in the top ten best tea-cultural routes of Guangxi in 2024. “Xiaohe Gudao” company operates under the “company + base + peasant household” model, covering over 2,000 mu (≈133 ha) of high-mountain tea gardens and providing employment for more than 300 local residents.

3. Botanical Description and Raw Material:

Variety / Cultivar: “Gui Zi” series (桂紫系列, Guì Zǐ xìliè) — new breeding lines of Camellia sinensis (L.) O. Kuntze, developed from local populations with natural anthocyanin mutation. Registered varieties: “Gui Zi 1 Hao” (桂紫1号) and “Gui Zi 2 Hao” (桂紫2号). Characteristic feature — stable year-round purple coloration of young shoots, unlike seasonal purple mutations in ordinary tea bushes, where violet color appears only episodically. The raw material belongs to the variety C. sinensis var. sinensis, bush form (灌木型, guànmù xíng) with small- and medium-leaf habit.
Morphology: Medium-height bush, compact, with good branching. Young shoots, buds, and first 2–3 leaves are colored in intense red-purple or violet; as they mature, the leaf blade acquires dark green tones while retaining purple tint on veins and petioles. Leaf surface is leathery with slight gloss.
Harvest: Spring harvest (March–April) — key for premium batches, when anthocyanin coloration is most intense. Summer-autumn leaf is used for red tea and blended batches. Winter harvest (冬片, dōngpiàn) is also possible for mild limited-edition batches.
Harvest standard: For green style — “one bud + one-two leaves” (一芽一叶 / 一芽二叶, yī yá yī yè / yī yá èr yè); for red — more mature leaf is acceptable (一芽二三叶, yī yá èr sān yè), providing fullness and sweetness to the liquor.
Raw material requirements: Uniform purple coloration of shoots without mechanical damage; careful hand picking with minimal delay between harvest and primary processing (no more than 4 hours for spring harvest).

4. Terroir and Cultivation:

Region: Hezhou Prefecture is located in northeastern Guangxi, at the junction with Guangdong and Hunan provinces. The 25° North latitude line crosses Hezhou, forming the so-called “golden latitude line” (黄金纬度线) for tea production in China.
Growing elevation: 250–800 m above sea level. The best batches come from high-elevation sites (500–800 m), where frequent fogs and cool nighttime temperatures slow shoot growth, promoting accumulation of aromatic precursors and anthocyanins.
Climate: Humid subtropical monsoon (亚热带季风气候). Average annual temperature 19.9°C, annual sunshine hours ≈1,587, annual precipitation 1,550 mm, frost-free period 299 days. High humidity and abundant diffused light — ideal conditions for synthesis of anthocyanins and L-theanine.
Soils: Acidic red soils and yellow soils (红壤 / 黄壤), formed on granite and sandstone-shale base, pH 4.5–5.5. Good drainage and richness in iron and manganese — classic conditions for tea bushes.
Agrotechnique: Purple-leaf forms are more sensitive to stress (drought, strong winds, direct sunlight), so quality sites practice protective plantings (shade trees), mulching with organic materials, controlled pruning. “Xiaohe Gudao” company applies environmentally clean production standards; the area of green and organic tea gardens in Hezhou reaches 9.58 万亩 (≈6,387 ha).

5. Production Technology:

The value of Hezhou Zi Cha lies in its “dual nature”: on one hand — freshness and purity of green style, on the other — berry-fruity depth of red. Technology is selected according to the desired style profile.

5.1. Green style (绿茶工艺, lǜchá gōngyì)

Picking (采摘, cǎizhāi): Selection of uniformly colored purple shoots; immediate delivery to factory.
Spreading and withering (摊晾, tānliàng): 1–2 hours in cool room for moisture equalization. Minimal — to preserve anthocyanin pigmentation.
Kill-green (杀青, shāqīng): Pan or drum method at 200–220°C; exposure time 3–5 minutes. Critically important not to overheat the leaf: excessive temperature destroys anthocyanins and gives coarse bitterness with smoky notes.
Rolling (揉捻, róuniǎn): Gentle mode (15–20 minutes) for forming twist and releasing cell sap without excessive tissue destruction.
Drying (烘干, hōnggān): Two-stage: primary at 100–110°C to ~15% moisture, final drying at 80–90°C to ≤6% moisture.
Control heating (复火, fùhuǒ): If necessary — light final heating for aroma stabilization.

5.2. Red style (红茶工艺, hóngchá gōngyì)

Picking — similar, more mature leaf acceptable.
Withering (萎凋, wěidiāo): Extended, 12–18 hours, until ~60% moisture loss; leaf becomes limp and pliable.
Rolling (揉捻, róuniǎn): More intensive than for green style, for maximum cell wall destruction and enzyme release.
Oxidation / fermentation (发酵, fājiào): 3–5 hours at 25–28°C and 90–95% humidity. Duration is selected to achieve honey-fruity sweetness without “flat” astringency. Anthocyanins partially transform during oxidation, giving complex red-amber hue to the liquor.
Drying (干燥, gānzào): Gentle, at 90–100°C, for aroma fixation and oxidation cessation.

5.3. White style (白茶工艺, báichá gōngyì)

Limited batches: gentle day/shade withering (48–72 hours) without kill-green and rolling, final drying at low temperature. Gives delicate “creamy” liquor with light floral line; rare and usually released in small editions.

6. Organoleptic Characteristics:

6.1. Green style

Dry leaf appearance: Twisted strips of dark green color with distinct purple sheen; under certain lighting, a “plum” luster is noticeable.
Dry leaf aroma: Floral (associations with orchid, lilac), with light berry note and freshness of green peas.
Liquor color: From light green to green-golden; in some batches, a barely perceptible pinkish reflection at the cup’s edge is possible — a visual marker of anthocyanin raw material.
Taste: Fresh, juicy, with mild sweetness and light, quickly disappearing bitterness. Umami component is pronounced due to high L-theanine content.
Aftertaste (回甘, huígān): Long, with “berry” or “floral” memory, sensation of pure freshness in the mouth.

6.2. Red style

Appearance: Tightly twisted dark strips with copper sheen; leaf is larger than green version.
Aroma: Honey, dried fruits (apricot, prunes), caramel sweetness, light spiciness.
Liquor color: Amber, deep and clear.
Taste: Dense, with honey-fruity center, mild tannins and velvety texture.
Aftertaste: Long, with notes of baked apple and caramel.

6.3. White style

Liquor: Pale yellow with lightest pinkish tint.
Taste: Delicate, “creamy,” with floral sweetness and weightless texture.

7. Chemical Composition:

The chemical profile of Hezhou Zi Cha is determined primarily by abnormally high anthocyanin content, distinguishing it from standard green and red teas.

Anthocyanins (花青素, huāqīngsù): Key marker of purple teas. For reference: in Yunnan’s “Zi Juan” variety (紫娟), the most studied representative of the group, anthocyanin content in young shoots (一芽二叶, spring harvest) reaches 29.14 mg/g — ~100 times higher than ordinary varieties. “Gui Zi” varieties are positioned as having “exceptionally high anthocyanin content” (花青素含量极高), suggesting comparable or similar levels.
Tea polyphenols (茶多酚, chá duōfēn): Approximately 22–30% (dry mass), depending on season and leaf maturity.
Catechins (儿茶素, ér chá sù): EGCG and total catechin content depends on technology: in green style, maximum amount is preserved; during oxidation (red style), catechins transform into theaflavins and thearubigins.
Caffeine (咖啡碱, kāfēi jiǎn): 2.5–4.0%.
Amino acids (氨基酸, ānjīsuān): 2.5–4.5%, including L-theanine (L-茶氨酸), providing characteristic umami and calming effect.
Volatile aromatic compounds: Purple teas have increased content of linalool, geraniol, and nerolidol, forming the floral-berry profile.

Note: specific figures for “Gui Zi” varieties are limited in open scientific access; given values reflect general ranges for purple-leaf teas of southern China and data on Zi Juan as the closest analog.

8. Health Properties:

Antioxidant activity: Anthocyanins possess pronounced ability to neutralize free radicals (reactive oxygen species). Studies of Yunnan’s Zī Juān showed that its DPPH (1, 1-diphenyl-2-picrylhydrazyl) free radical scavenging ability positively correlates with anthocyanin content.
Blood pressure effects: In laboratory animal experiments, green tea from Zi Juan demonstrated blood pressure reduction of 35.53%, exceeding ordinary Yunnan green tea (29.04%). This is attributed to synergistic action of anthocyanins and catechins.
General effects: Cognitive function support (L-theanine), mild stimulation (caffeine), digestion aid (polyphenols). According to traditional Chinese medicine, tea of “purple nature” possesses “cooling” properties (凉性, liáng xìng), which may be beneficial for excessive “heat” in the body.
Practical caveat: Increased anthocyanin content does not make tea a medicinal product. All health claims are based on laboratory data and general polyphenol properties; clinical studies on humans for this specific tea are absent.

9. Brewing:

Soft water with moderate mineralization (TDS 50–150 mg/L) is recommended to not suppress delicate floral-berry notes.

9.1. Gongfu (flash steeps, 功夫泡法)

Warm vessels with boiling water.
Tea amount: 5–6 g per 100 ml (green style) or 5–7 g per 100 ml (red style).
Rinse (润茶, rùnchá): 2–3 seconds — optional; for green style can be skipped.
First steep: 10–15 seconds.
- Green style: 75–85°C.
- Red style: 88–93°C.
- White style: 80–85°C.
Subsequent steeps: 8–12 steeps, adding 5 seconds each time.

9.2. Pot/cup brewing (大壶泡法)

2–3 g per 200–250 ml, 80–85°C (green) / 90°C (red), 2–3 minutes.
Don’t overbrew: bitterness from oversteeping masks the delicate berry profile.

9.3. Cold brewing (冷泡法, lěng pào fǎ)

5 g per 500 ml cold water (room temperature or refrigerated), 4–8 hours. Excellently reveals floral and berry notes, gives visually striking liquor with pinkish tint.

Vessels: White porcelain gàiwǎn (白瓷盖碗) or glass teapot — for full color control and visual pleasure.

10. Storage:

Green style: Airtight packaging (foil bag with valve or tin can), protection from light, moisture, foreign odors. Optimal — in refrigerator at 0–5°C. Storage period without losing top notes — 6–12 months.
Red style: Less sensitive; dry, dark, cool place. With proper storage, develops and deepens over 1–2 years.
White style: Suitable for multi-year aging (analogous to Fuding white tea): “one year — tea, three years — medicine, seven years — treasure.”
General rule: Anthocyanins are sensitive to light and oxygen; for all styles, airtightness is critically important.

11. Price and Authenticity:

Price range: Depends on raw material status (plantation bush tea / semi-wild trees), season (early spring “Ming Qian” — more expensive), processing style and grade. Premium spring batches of green style from high-mountain “Gui Zi” gardens — upper segment. Red and blended versions — middle.
Typical substitutions:
- Ordinary green tea with artificial coloring or flavoring, marketed as “purple.”
- Tea from seasonal purple mutations (temporary anthocyanin coloration), passed off as genetically stable “Gui Zi” variety.
- Yunnan Zi Juan sold under Hezhou Zi Cha brand (different terroir and flavor profile).
How to recognize authentic:
- Real Gui Zi retains purple tint even in mature leaves (not only in bud).
- Aroma — natural, floral-berry, without “perfumery.”
- Spent leaves (叶底, yèdǐ) after brewing demonstrate stable purple coloration of veins.
- Buy from verified sellers with documented origin (district/village/producer); suspiciously low price almost always signals substitution.

12. Interesting Facts:

The quote from Lu Yu’s “Cha Jing” “茶，紫者上” (“among teas, purple is the finest”) historically referred to wild purple mutations and reflected the perception of their rarity and superior taste qualities. Hezhou Zi Cha is one of the few modern teas purposefully embodying this ancient formula.
“Gui Zi” is the only registered breeding series of purple teas in Guangxi. Yunnan’s “Zi Juan” was recognized as a new variety by China’s State Forestry Administration (国家林业局) in 2005 (certificate № 20050031), while “Gui Zi” is a product of later, regional breeding program.
Hezhou Zi Cha is ideal for comparative “paired” tastings: green and red versions from the same raw material clearly demonstrate how processing technology transforms color, aroma, and liquor character.
The total area of tea plantations in Hezhou Prefecture exceeds 300,000 mu (≈20,000 ha), and annual dry tea output in 2024 was 24,700 tons with primary production value of 1.315 billion yuan — Hezhou ranks among the largest tea-producing cities in Guangxi.

14. Varieties and Grades:

Hezhou Zi Cha — green style (贺州紫绿茶): Maximum freshness, herbal-floral line, clear green-golden liquor. Raw material standard: 一芽一叶 — 一芽二叶.
Hezhou Zi Cha — red style (贺州紫红茶): Dense, with honey and dried fruits, mild texture. Standard: 一芽二叶 — 一芽三叶.
Hezhou Zi Cha — white style (贺州紫白茶): Delicate, “creamy,” with floral sweetness. Limited edition, gentle withering.
Hezhou Zi Cha — Liú Bǎo style (贺州紫六堡): Experimental batches using post-fermented Liú Bǎo tea technology (六堡茶工艺); appeared against the backdrop of active development of Guangxi Liu Bao in the 2020s. Characterized by complex “earthy” profile with fruity overtones.

15. Contraindications:

Caffeine sensitivity: Standard precautions — not recommended before sleep and with individual caffeine intolerance.
GI diseases: Green style on empty stomach may irritate mucosa in people with gastritis or reflux; red style is tolerated more gently.
Medication intake: Tea polyphenols may reduce bioavailability of some drugs (iron supplements, certain antibiotics). 1–2 hour interval between tea and medication intake is recommended.
Pregnancy and lactation: Moderate consumption (1–2 cups daily) is considered safe; when in doubt — consult physician.
Anthocyanins and acidity: At high anthocyanin doses (atypical for normal tea drinking), theoretical influence on urine pH is possible; has no practical significance with normal consumption.

In conclusion:

Hezhou Zi Cha is the embodiment of the ancient wisdom of Lù Yǔ about the superiority of purple tea in modern interpretation. The breeding series “Guì Zǐ” (桂紫) has given the world a unique tea, where high anthocyanin content creates not just a visual effect, but forms a special flavor profile — from fresh floral-berry juiciness of green style to honey-fruit depth of red. This tea will be a discovery for those seeking new facets in classical categories of Chinese tea, for connoisseurs of rare varieties and lovers of visually striking infusions with pinkish shimmer.

Hezhou Zi Cha offers a multidimensional experience: it is both meditative contemplation of purple leaves in a gaiwan, and enjoyment of long floral aftertaste, and the opportunity to trace how the same raw material unfolds in different processing styles. Thanks to the balance of freshness and sweetness, delicacy and fullness, this tea is equally good for morning meditation and evening tea ceremony with friends, opening the path to understanding why purple tea was considered a treasure even during the Tang dynasty.
