Cultivars

Da Ye Zhong translates as “big-leaf variety,” and the name is accurate. Unlike the small-leaf Camellia sinensis var. sinensis that predominates across most Chinese and Japanese tea regions, Da Ye Zhong is Camellia sinensis var. assamica. Wider leaves, bigger buds, more caffeine, more catechins, more body.

Yunnan is where Da Ye Zhong is at home. The province's subtropical climate and the native presence of assamica tea plants, some of the oldest tea trees in the world growing wild on Yunnan's southern mountains, make it the backbone of Chinese tea. Almost every puer you will ever drink, sheng or shou, is Da Ye Zhong. So is every Yunnan black tea. Dian Hong, the honey-sweet red tea from western Yunnan, is Da Ye Zhong. Yue Guang Bai, the moonlight white, is Da Ye Zhong processed as white tea.

What the cultivar delivers: a thicker, rounder mouthfeel than sinensis teas, stronger body, a characteristic sweetness that lingers in the throat (huigan). The leaves are large enough that a well-made cake can be unfolded and studied. A gushu sheng puer cake from a village like Laobanzhang can show intact leaves longer than a thumb.

Gushu (古樹, old-tree) describes the age of the tree, not a different cultivar. Da Ye Zhong grown on wild, semi-wild, or ancient plantation trees, three to eight hundred years old and sometimes older, produces tea materially different from the same cultivar on young bush plantations. Deeper roots, more terroir expression, richer chemistry. The price difference can be an order of magnitude.

Da Bai translates as “big white,” a reference to the dense silvery down (bái háo) that covers its unopened buds. Selected in Fuding county, Fujian, the cultivar is the backbone of Chinese white tea.

Every serious Silver Needle (Bai Hao Yin Zhen) is made from Da Bai buds plucked in a narrow window in early spring. The buds are sun-withered, dried, and nothing else. Bai Mu Dan, which uses one bud and two leaves, is Da Bai pluck from slightly later in the season. Shou Mei, the late-season everyday grade, is mature Da Bai leaves.

The cultivar's character: sweet, subtle, floral, low in astringency, with a honeyed quality that develops further as white tea ages. Da Bai has a close cousin, Da Bai Hao, used specifically for Silver Needle by some producers; the two are closely related and sometimes used interchangeably.

Yunnan has its own white tea tradition, but the plants there (Yue Guang Bai) are Da Ye Zhong processed as white tea, not Da Bai. If the cake is from Fuding or Zhenghe in Fujian, it is Da Bai. If it is from Yunnan, it is not.

Tieguanyin means “Iron Goddess of Mercy,” and it is both a cultivar and the tea made from it. Selected in Anxi county, Fujian, in the early eighteenth century, Tieguanyin is one of the most famous Chinese tea cultivars by name, and one of the most tightly bound to a single tea style.

The tea is a ball-rolled oolong, medium-to-heavy oxidation (traditionally 30-50%), with two distinct roasting styles. Qingxiang (light fragrance) Tieguanyin is lightly oxidised and unroasted, green and floral, with an orchid-jade character that has dominated the market since the 1990s. Nongxiang (rich fragrance) Tieguanyin is the older roasted style, darker, sweeter, with roasted-grain and dried-fruit notes that age well. A well-aged Nongxiang can show mineral, medicinal, and woody character after a decade.

The Iron Goddess name comes from a legend: a poor farmer took scrupulous care of a neglected Guanyin shrine and was rewarded with a single tea seedling hidden in a rocky crevice. The plant's hard, dark, iron-like leaves gave the cultivar its name. The legend hints at the terroir that suits Tieguanyin: volcanic, mineral-rich, mountainous slopes.

Rou Gui means “cinnamon bark,” and the cultivar was named for the warm, woody, spicy character its roasted oolongs deliver. It is one of the four “famous bushes” (si ming cong) of Wuyi's traditional yancha (rock tea) pantheon.

Grown in the rocky soils of the Wuyi mountains in northern Fujian, Rou Gui is bred for yancha processing: charcoal-roasted, usually two or three times over weeks, developing the warm spice-and-smoke notes that name it. A well-roasted Rou Gui from the protected rock core (zhengyan) of the Wuyi scenic area shows cinnamon bark, dried fruit, mineral rock, and a thick, coating mouthfeel. Each re-roasting cycle deepens the character without bitterness.

Sub-strains exist: Niu Lan Keng Rou Gui, Ma Tou Rou Gui, Huiyuankeng Rou Gui, each named for the rocky gulley it grows in. These are among the most expensive teas in the Wuyi canon. The closest cultivar in character is Da Hong Pao: Rou Gui tends toward cinnamon-warmth, Da Hong Pao toward mineral-roast complexity.

Da Hong Pao means “Big Red Robe,” and the legend is as famous as the tea. A scholar travelling to take the imperial exam fell ill, and was saved by a monk at Wuyi Mountain who brewed him tea from six old bushes on a cliff. The scholar passed, returned with a red robe as thanks, and draped it over the bushes. The tea from those bushes has been called Da Hong Pao ever since.

The legendary mother bushes still grow on Tianxin cliff at Wuyi, now protected as a national treasure. The tea sold as Da Hong Pao today is almost never from those specific bushes. It is a blend of several yancha cultivars, a clonal cultivar propagated from the mother bushes, or simply a high-quality Wuyi yancha sold under the Da Hong Pao name.

This is not a fraud, exactly. The legendary six bushes could never produce enough tea to meet demand. Modern Da Hong Pao has been defined functionally: heavily roasted, darkly oxidised Wuyi yancha with a particular mineral-roasted-fruit character. The zhengyan core of the scenic area produces the best examples. The banyan (half-rock) peripheral zones produce more accessible ones.

What to expect in the cup: roasted chestnut, dark plum, mineral rock, a long cooling finish. Da Hong Pao ages well, particularly the more heavily roasted examples, sometimes for decades.

Ya Shi Xiang translates as “Duck Shit Fragrance,” which is the kind of name tea farmers give a thing to keep it in the family. The story, as told by the Wugang village in Phoenix Mountain, Guangdong: a local farmer discovered a bush with an exceptional aromatic cup. Worried neighbours would steal cuttings, he named the cultivar Ya Shi Xiang to discourage them. Nobody would ask for cuttings of a tea called duck shit. The name stuck.

The cultivar is one of dozens of Feng Huang Dan Cong (Phoenix Single Bush) clonal varieties, each named for the aroma it delivers. Ya Shi Xiang produces a tightly-twisted oolong with a clear orchid-honey fragrance and a lively, complex cup that has become one of the most in-demand Dan Cong styles of the last decade. Younger drinkers, in particular, like its clarity.

The cultivar is specific to Phoenix Mountain (Fenghuang Shan) in eastern Guangdong. Attempts to plant it elsewhere have produced tea that is recognisably Dan Cong but not recognisably Ya Shi Xiang. The granitic mineral soils and specific elevation band seem to matter.

A practical note: the name Ya Shi Xiang is now used loosely by non-Phoenix producers for any Dan Cong-style tea with a similar aromatic profile. For authentic cultivar material, look for single-village specification and ideally single-bush or single-garden provenance.

Purple-leaf tea has caught the specialty market's imagination over the last decade, and the names deserve sorting out. The two circulating most often are Zi Ya (紫芽, “purple bud”) and Zi Juan (紫鵑, “purple cuckoo”). They are not the same thing.

Zi Ya is the older, heirloom category. It refers to wild-growing arbor tea trees in Yunnan whose naturally purple-tinged buds likely come from anthocyanin accumulation in response to high-altitude UV exposure. Zi Ya is not a clonal cultivar but a population of Camellia sinensis var. assamica trees whose purple character emerges inconsistently, bush by bush. When it does, the tea shows a wild, slightly bitter, slightly savoury character that puer drinkers describe as unusually structured.

Zi Juan is the modern clonal cultivar. Developed in 1985 at the Yunnan Tea Research Institute as TCFS Purple No. 1, Zi Juan was selected for reliable purple-leaf production and relatively high anthocyanin content. It is now grown widely across Yunnan and marketed as a health-forward tea. The leaves and liquor are visibly purple, and the cup tends to be astringent with a cooling finish.

What the hype is about: anthocyanins are antioxidant pigments with some evidence of anti-inflammatory properties. The research is preliminary, and the dietary-dose question is open (the general framework of how to think about tea compound claims is covered in our theabrownin piece). What is certain is that purple tea looks striking and produces a cup unlike any other cultivar. That is enough to explain the demand.

Xiao Zhong means “small variety,” and the cultivar is the historical foundation of Chinese red (black) tea. Grown in the Tongmu village area of Wuyi Mountain in Fujian, Xiao Zhong is the source material for Zhengshan Xiaozhong, the original smoked red tea that Portuguese and Dutch traders carried to Europe in the seventeenth century, and for Jin Jun Mei, the luxury bud-only red tea developed in 2005.

The cultivar is a small-leaf Camellia sinensis var. sinensis adapted to the cool, humid, heavily forested Tongmu protected area. Its small buds and leaves concentrate amino acids and sugars, part of why the teas made from it tend toward honey, dried fruit, and floral notes rather than the maltier character of Yunnan or Assam reds.

Two processing styles define the range. Zhengshan Xiaozhong (Lapsang Souchong)is traditionally smoked over pine fires, which gives the classic campfire-leather character British drinkers came to know as “Russian caravan” tea. Unsmoked Zhengshan Xiaozhong is the modern version, revealing the cultivar's floral and longan-fruit character without the smoke. Jin Jun Mei is a bud-only preparation, hand-processed, delicate and honeyed, and one of the most expensive Chinese teas by weight.

Xiao Zhong also refers, more loosely, to the family of small-leaf Wuyi cultivars used across the broader red tea production of the region. When the literature says “Xiao Zhong red tea,” it usually means this loose category.

Shui Xian means “water sprite” or “narcissus,” one of Wuyi's oldest yancha varieties. Grown since the early nineteenth century, it produces a rounder, sweeter, more floral oolong than Rou Gui or Da Hong Pao, with characteristic orchid and stone-fruit notes. Also used for older-style darkly roasted yanchas and some Phoenix Dan Cong. Aged Shui Xian (lao cong) from very old trees is prized for depth and cooling minerality.

Huangjin Gui means “Golden Osmanthus,” the sister cultivar to Tieguanyin in Anxi. Lightly oxidised, ball-rolled, distinctly yellower in both leaf and liquor than its famous sibling. It produces a more overtly floral cup with a pronounced osmanthus-blossom fragrance that comes from the cultivar's own chemistry, not added scenting. Often dismissed as a lower-grade alternative to Tieguanyin, but well-made Huangjin Gui stands on its own. The fragrance is singular.

Qimen is the cultivar and the region behind Keemun (祁門紅茶), one of the classic three Chinese red teas. Grown in Qimen county in southern Anhui, the small-leaf Qimen cultivar produces a red tea with a distinctive “Keemun fragrance”: toast, dark chocolate, dried rose, and a clean orchid finish. Selected specifically for red tea production in the 1870s, unusual among Chinese cultivars, most of which were selected for green tea and only later adapted. Keemun was an English breakfast-tea staple before India and Ceylon dominated that market.

Anhua Qunti Zhong translates roughly as “Anhua seed population,” the heterogeneous tea-plant population grown in Anhua county, Hunan, for Hunan dark teas: fuzhuan brick, qianliang cha, and heizhuan. Not a clonal cultivar but a genetically diverse landrace, adapted over centuries to the specific pile-fermentation processing of Hunan darks. The large leaves and the heterogeneity both matter: different bushes contribute different components to the finished brick's complex character. Related to Da Ye Zhong but locally distinct.

Yibang Xiao Ye means “Yibang small leaf,” a specific small-leafed assamica variety unique to the Yibang mountain in the Ancient Six Tea Mountains of Xishuangbanna, Yunnan. Unlike the broader Da Ye Zhong population that dominates Yunnan, Yibang's small-leafed plants produce a sheng puer with unusual delicacy and mineral sweetness, closer to a Chinese oolong than a typical puer. Production is limited. Yibang sheng is one of the most sought-after single-mountain styles among collectors, alongside Bingdao and Laobanzhang.

Xing Ren Xiang means “almond fragrance,” one of the original Ten Famous Aromas of Phoenix Dan Cong. Grown on Wu Dong mountain in Guangdong's Phoenix mountains, it produces a tightly-twisted dark oolong with a distinct bitter-almond character, closer to marzipan or apricot pit than to sweet almond. Medium-heavy oxidation, light to medium roasting, long straight leaves. Considered one of the more elegant Dan Cong styles, preferred by drinkers who want structure and length over the more immediate floral explosion of Ya Shi Xiang or Mi Lan Xiang.

Yu Lan Xiang means “magnolia fragrance,” one of the most classical Phoenix Dan Cong aromas. Old-bush Yu Lan Xiang from Wu Dong mountain can show a clean, clear magnolia note that is unmistakable once you have met it. Clean, slightly sweet, long in the finish. Bushes over a hundred years old produce a cup with depth that newer plantings cannot reproduce. Medium oxidation, traditional roasting.

Song Zhong means “Song variety,” a Phoenix Dan Cong lineage supposedly dating to the Song dynasty. Mother trees on Wu Dong mountain are protected under local heritage designation and can be centuries old. Song Zhong produces some of the most layered, complex Dan Cong teas available, with a signature shan yun (mountain rhyme) mineral character and an aroma that shifts across multiple infusions. Almost always sold as expensive limited-edition production. One of the most costly Chinese oolong styles by weight.

Zhi Lan Xiang means “iris orchid fragrance.” One of the principal Phoenix Dan Cong aromas. The fragrance the name promises is real: a cool, almost waxy floral note, more contained than Yu Lan Xiang's magnolia and less tropical than Mi Lan Xiang's honey-lychee. A more cerebral Dan Cong style, often preferred by drinkers who have worked their way through the more immediately fragrant varieties and want complexity over impact.

Qing Xin means “green heart,” a reference to the tender green colour of its young buds. It is Taiwan's signature oolong cultivar and the foundation of the island's high-mountain tea reputation.

The cultivar came to Taiwan from Fujian in the nineteenth century and was selected over generations for the central mountain range. It thrives above 1,000 metres, where daily fog and cool nights slow growth and concentrate sweetness. Nearly every famous high-mountain oolong from Taiwan (Ali Shan, Li Shan, Shan Lin Xi, Da Yu Ling) is Qing Xin.

What the cultivar delivers: a creamy, buttery, orchid-floral character, a clean mineral finish, and a lingering huigan sweetness. Light oxidation (around 15-25%) and ball-rolling preserve the fragrance. A well-made high-mountain Qing Xin opens into long strip leaves after brewing, with a clear pale-jade liquor.

Qing Xin is also the cultivar used for Dong Ding (the heavier-roasted, older-style Taiwanese oolong) and for Oriental Beauty (where Qing Xin Da Mao, a related sub-variety, is plucked after leafhopper damage to produce the muscat-fruit character). Modern cultivation has bred derivative cultivars, Jin Xuan and Sijichun among them, that are easier to grow and more productive, but purists still consider Qing Xin the taste standard.

Jin Xuan means “Golden Daylily,” named by the Taiwanese tea master Wu Zhen-Duo for his grandmother. It is the most famous of the cultivars bred by the Taiwan Tea Research and Extension Station, released as TRES #12 in 1981.

Jin Xuan was bred for Taiwan's oolong market. It is more productive than Qing Xin, more resistant to disease, and faster to grow. But it produces a distinctive cup: buttery, with a milky note that earned it the nickname “milk oolong” (naixiang). The milky character is not added. It comes from the cultivar's own chemistry, which carries elevated levels of compounds that read as lactonic on the palate.

The downside of Jin Xuan's popularity has been a proliferation of flavoured “milk oolongs” that add actual milk or cream flavouring to lower-grade base teas. Authentic Jin Xuan from a reputable Taiwanese producer is a cultivar story, not a flavour-additive one. The distinction matters.

Jin Xuan is grown across a wider elevation band than Qing Xin, from lowland farms around Mingjian to high-mountain gardens at Shan Lin Xi. The high-mountain versions show cleaner fragrance and better length; the lowland versions emphasise the milky character more strongly.

Si Ji Chun means “four seasons spring,” selected at Muzha, Taipei County, in the 1980s for its remarkable productivity. Unlike Qing Xin or Jin Xuan, which harvest primarily in spring and winter, Si Ji Chun flushes reliably four to five times per year. Grown mostly at lower elevations in Nantou, the cultivar produces a light, aromatic, slightly gardenia-floral oolong. Considered an everyday tea in Taiwan, not a connoisseur's choice, but popular precisely for its year-round availability and consistent character.

Yabukita is the cultivar that made Japanese tea. Selected in 1908 by Hikosaburo Sugiyama, an amateur tea breeder in Shizuoka, registered as a named variety in 1953, and since then nearly monopolistic. Recent estimates put Yabukita at roughly 70% of Japan's tea-growing area.

What made Yabukita dominant was its balance of traits: cold-hardy enough for Japan's mountain tea regions, commercially productive, and with a leaf chemistry that produces the clean umami character of modern Japanese greens. Sencha, gyokuro, matcha (in tencha form), hojicha, genmaicha: Yabukita is the backbone of all of them.

The cup character is familiar to anyone who has drunk Japanese tea: bright green colour, fresh cut-grass aroma, umami sweetness with a clean, slightly astringent finish. Shade-grown Yabukita (for gyokuro and matcha) concentrates amino acids and produces the rich, savoury, almost brothy character those teas are known for.

The monoculture has costs. Yabukita's dominance means alternative cultivars (Saemidori, Asatsuyu, Okumidori, Yutakamidori, all detailed below) are often valued as “difference” rather than as traditions in their own right. A growing movement among Japanese producers is rebalancing the cultivar mix, partly for flavour diversity and partly as resilience against climate change. The next decades of Japanese tea will look different from the last.

Zairai means “native.” The term refers not to a single cultivar but to the genetically diverse seedling-grown populations that predated modern clonal cultivation in Japan. Before Yabukita's dominance spread in the mid-twentieth century, Japanese tea farms were mostly Zairai. The populations persist today in a handful of older gardens, particularly in remote valleys of Shizuoka, Miyazaki, and Nara. Zairai teas are praised for their complexity, and because each garden's population produces a different cup: the opposite of the uniformity Yabukita's monoculture delivers. A growing specialty interest among Japanese tea drinkers.

Saemidori means “clear green,” released in 1990 as a cross between Yabukita and Asatsuyu. It produces a distinctly clear, bright green cup with pronounced umami and sweetness, lower astringency than Yabukita, and faster processing. Grown mostly in Kagoshima prefecture in southern Japan, where the warmer climate suits it. Saemidori now accounts for a small but growing share of high-end gyokuro production, prized for its lower bitterness and more pronounced sweetness than Yabukita-based gyokuro.

Asatsuyu means “morning dew,” often called “natural gyokuro” in Japanese tea circles. Selected in Kagoshima in the 1950s, it naturally produces the high-amino-acid character that other cultivars require shading to achieve. Asatsuyu's unshaded sencha can show the sweet umami depth that normally needs twenty days under mesh nets. Rare and commercially niche because it is less productive and harder to grow than Yabukita, but prized by producers making premium unshaded greens.

Yutakamidori means “abundant green,” the second-most-planted cultivar in Japan after Yabukita, especially in Kagoshima. Selected for early harvest, Yutakamidori's first flush comes a week or more before Yabukita's, and for strong, rich flavour. Cups tend to be deeper green in colour and more vegetal than Yabukita, with a slightly heavier mouthfeel. Commonly used for fukamushi (deep-steamed) sencha, where its chemistry holds up to the longer steaming process that would flatten a more delicate cultivar.

Okumidori means “late green,” a reference to its late harvest window, the cultivar's first flush comes after Yabukita's. Selected in the 1960s specifically for matcha production, Okumidori is now one of the preferred cultivars for high-grade ceremonial matcha in Uji and Nishio. Its leaves produce a vivid, saturated, deep-green matcha powder with a rich umami flavour and notably low bitterness. Increasingly used for premium single-cultivar matcha. An important counterpoint to the Yabukita monoculture.

Samidori means “fresh green,” developed in Uji, Kyoto, specifically for gyokuro and tencha (the base leaf for matcha). Registered in 1954. Its leaves are particularly responsive to shading, which is why it is one of the most-used gyokuro cultivars alongside Asatsuyu and Okumidori. The cup is sweet, thick-bodied, with deep umami and minimal bitterness. Samidori also has a distinct deep emerald-green colour when ground into matcha, which is part of why the cultivar remains central to high-grade matcha production in Uji.

Korea's native seedling-grown tea population, descended from seeds brought from Tang China in the 828 CE imperial planting at Jirisan. Unlike Japan's Yabukita or Taiwan's Qing Xin, Jaerae-jong is not a uniform cultivar but a genetically diverse population of small-leaf sinensis plants that have adapted to Korean conditions over eleven centuries. Concentrated in Hadong's wild and semi-wild fields. Hand-plucked, pan-fired in the Korean deokkeum style. Produces a rounder, slightly toastier cup than Japanese steamed greens. More heterogeneous than a clonal cultivar by design: each bush's expression is slightly different, which is the point.

AV2 (Ambari Vegetative 2) is an Indian tea cultivar developed at the Tocklai Tea Research Institute in Assam, released in the 1970s. One of the most widely planted cultivars in Darjeeling's second and third flush production, where its responsiveness to oxidation produces the muscat-fruit character the region is famous for. Assam and Ceylon tea cultivation uses many such clonals (UPASI, United Planters' Association of Southern India, varieties and China-assam hybrids) developed for productivity, disease resistance, and cup quality. AV2 is the most famous by name.

Ceylon's tea industry grew from assamica stock transplanted from India in the nineteenth century, supplemented with China-jat seedlings. Modern Ceylon cultivation uses a range of clonal cultivars (TRI 2023, TRI 2025, DN series) bred by the Tea Research Institute of Sri Lanka for the island's specific elevation bands. Low-grown, mid-grown, and high-grown Ceylon teas are all produced primarily from these clonals. The character is well-known: bright, brisk, citrus-and-malt notes, suited to both strong plain brewing and milk.
