Oolong Grades and Cultivars

A bag of oolong can carry a grade from four entirely different systems, and they are not interchangeable. A sensory tier such as Anxi's te ji, Special Grade, certifies how a finished tea tastes and looks against a national standard. A cultivar registration, a Taiwan Tea number or a Chinese national-committee approval, certifies which plant the leaf came from, and has nothing to do with how well any one harvest turned out. A trade aroma-type name, one of Phoenix Dancong's ten fragrances, describes a taste family, not a rank. A competition award, judged once against that year's field of entries, is neither a permanent tier nor a claim about the plant. This is the reference on what each system actually certifies, how the four origins grade differently, and how a named cultivar becomes a named cultivar in the first place.

Four things called a grade, and what each one certifies

None of the four ranks the others. A tea can be a registered cultivar, sold under an aroma name, entered in a competition, and sorted into a sensory grade, four separate facts about the same leaf, and a seller who quotes only one of them is not lying, just answering a narrower question than the one a buyer usually means to ask.

Anxi's tiered standard, oolong's clearest sensory ladder

Of the four classic origins, Anxi keeps the most explicit tiered sensory grade, and it is where a novice learns to read one. China's national standard for Anxi Tieguanyin, most recently revised as GB/T 19598-2025¹ (published February 28, 2025, effective September 1, 2025, replacing the 2006 edition), splits finished tea into three aroma-based product types before it grades any of them. Qing xiang, light aroma, is made with light fermentation and a light roast to preserve a fresh, floral character; the standard sorts it into four sensory tiers, Special, First, Second, Third, defined by exact descriptive language: Special Grade calls for a sand-green, oily-looking leaf, tight and plump, a clear and lasting orchid-like aroma, a fresh and sweet taste that leaves the throat smooth, and a pale golden liquor tinged green. Nong xiang, dark aroma, is roasted harder, commonly cited at 120 to 180°C (about 250 to 355°F), breaking down more chlorophyll for a darker leaf and a heavier, caramel-and-roasted-rice register; it carries one tier more than the light type, Special through Fourth, five grades in all. The 2025 revision adds a third category, chen xiang, aged aroma: tea blended, roasted, and stored for at least five years before release (Jiemian News⁵).

No comparable multi-tier national sensory standard exists yet for the other three origins. Wuyi's own national standard, GB/T 18745², instead splits yancha into five product categories and grades four of them, on ladders that do not all top out at the same tier: Da Hong Pao and Rou Gui each run Special through Second⁴, Shui Xian and Qi Zhong run Special through Third. Only the named cultivars, the ming cong, carry no fixed tiers, judged each as its own singular thing rather than sorted into one. The full account of that split, and the mineral zhengyan zoning that runs alongside it, is its own reference.

Taiwan's two systems, and why they are not the same grade

Taiwan runs sensory grading through a different mechanism entirely: not a written national standard applied to every harvest, but an annual competition, organized locally rather than by one central body. More than thirty separate competitions run each year, hosted by county and township farmers' associations, agricultural improvement stations, and the tea research station itself, and each one sets its own tier names (chayanso.com⁶). Judging runs two stages, a dry-leaf assessment (shape, color, uniformity) and a wet assessment of the brewed cup, weighted roughly aroma 30 percent, taste 40 percent, appearance and spent leaf 20 percent, liquor color 10 percent. Awards commonly run four deep: Special Grade for the top handful of entries (occasionally 3 to 10 times the price of ordinary commercial tea of the same cultivar), then First, Superior, and Standard grades below it, though the exact tier names and how many entries each covers vary by organizing association and by year. A competition grade is a one-time verdict on one batch, never a claim about the plant, and it is not interchangeable with a commercial retail grade, which reflects ordinary market tiering with no competitive judging behind it at all.

That competition system grades the harvest. It has nothing to do with Taiwan's separate system for certifying the plant, the government cultivar-registration pipeline that produced the Taiwan Tea numbers behind Jin Xuan, Cui Yu, and every other Taiwan-bred oolong cultivar, detailed in full in its own account of how a new cultivar reaches a nursery. A tea can carry a Taiwan Tea number, a competition ribbon, and a retail grade, and none of the three tells you the other two.

Phoenix Dancong's aroma names: what the bush smells of, not where it ranks

Phoenix Dancong (Fenghuang Dancong) uses a classification system unlike any of the other three origins: not a tier at all, but a name for the taste the bush itself produces. Trade convention sorts the mountain's named bushes into ten aroma types, shi da xiang xing: huang zhi xiang (gardenia), zhi lan xiang (orchid), yu lan xiang (magnolia), mi lan xiang (honey orchid), xing ren xiang (almond), jiang hua xiang (ginger flower), rou gui xiang (cinnamon), gui hua xiang (osmanthus), ye lai xiang (night-blooming jasmine), and mo li xiang (jasmine) (The Paper⁷). Growers cross-classify the same bushes by leaf size (large, medium, small), leaf color (dark, red-tinged, pale), and picking period (extra-early through late), so a single named tea can carry several labels at once, an aroma name, a leaf type, and a harvest window, layered rather than ranked. Whether the ten names hold up to laboratory scrutiny, and how finely the chemistry actually separates them, is a question this site has already put to a gas chromatograph; the answer is its own account. None of the ten names is a quality tier. A mi lan xiang is not better than a xing ren xiang, only a different bush.

What a cultivar actually is

Every named oolong bush, Jin Xuan, Tie Guanyin, Rou Gui, Ying Zhi Hong Xin, is a cultivar: a single genetic line, propagated so that its exact characteristics breed true rather than recombining the way a seed-grown plant's would. Tea propagates by one of two systems. Asexual (clonal) propagation, cutting, grafting, layering, or division, produces a plant genetically identical to its single mother; nearly every named commercial cultivar, Jin Xuan included, is asexual for exactly this reason, because a cutting is the only way to guarantee the next bush smells like the one the name was chosen for. Sexual propagation, growing a new plant from seed, recombines the parents' traits and drifts from generation to generation; it is how a breeding program creates a genuinely new candidate line in the first place, but not how an established named cultivar is then multiplied for sale (Hunan Supply and Marketing Cooperative⁸).

Getting a name certified runs through a government pipeline on both sides of the strait, though the two run through different institutional doors. China established a national tea-cultivar review committee in 1981; across five review rounds between 1984 and 2012 it certified 124 national-level cultivars, 17 bred from seed and 107 propagated clonally, after each cleared a provincial review first (Hunan Supply and Marketing Cooperative). Taiwan runs one station, the Tea and Beverage Research Station, through four fixed field stages, crossing and nursery, single-plant selection, strain comparison, and regional trial, typically fourteen to twenty-one years before a candidate is even named, then a separate plant-variety-rights process before a nursery may legally sell it. The full pipeline, staged year by year, and what it took to get Taiwan's newest release, Taiwan Tea No. 26, from imported 1960s seed stock to a namable cultivar, is documented in full here; the specific case of Jin Xuan, and how its breeder hid the name's real origin for two decades, is its own story. Confirming that an existing plant really is the cultivar it is sold as is a separate question again, one a 2009 genetic test answered for the six surviving Da Hong Pao mother bushes on Jiulongke, covered here.

Why "Special Grade" on two bags can mean two unrelated things

The confusion these four systems cause is almost always the same confusion: two sellers print the same word, and each is telling the truth about a different system. Anxi's Special Grade is a state sensory tier, reassessed on every batch against GB/T 19598's written descriptive standard. A Taiwan competition's Special Grade is a one-time verdict a local association's judges reached on one year's entries, worth several times the price of ordinary tea precisely because it is rare and not repeatable. Neither Special Grade says anything about the other, and neither says anything at all about whether the leaf is Jin Xuan or Tie Guanyin or a cultivar with no government registration behind its name at all. A cultivar name, a sensory tier, an aroma-type label, and a competition result are four separate certifications, issued by four different bodies for four different reasons, and a bag is free to carry any combination of them, or none. Knowing which system a printed grade belongs to, not the grade itself, is what actually tells a buyer what they are holding. Read the system first, then the grade.
