Quick answer — what is a matcha cultivar?
A cultivar is the specific tea plant variety a matcha is made from — Okumidori, Saemidori, Samidori, Yabukita. It is not a grade and not a region: cultivar tells you the plant's genetics, region tells you where it grew, and grade tells you nothing regulated at all. Single-cultivar matcha names the plant on the tin.
Five years ago almost no matcha tin told you what plant the tea came from. Today cultivar names sit on labels from Los Angeles to London, and buyers search for Okumidori or Samidori by name — some of our own customers found us exactly that way. The information was always there; Japanese producers have bred, registered and argued about tea cultivars for a century. What changed is that drinkers started asking.
This guide is the map: what a cultivar actually is, how the important ones relate to each other, and what each tastes like as matcha — with links to our full profiles of every cultivar we carry.
Cultivar, grade or region? The three words on the tin
Most confusion about matcha comes from mixing three different kinds of label. They answer three different questions:
| Label type | What it tells you | Examples |
|---|---|---|
| Cultivar | The plant's genetics — a registered, cutting-propagated variety of Camellia sinensis | Yabukita, Okumidori, Saemidori, Samidori, Seimei |
| Region | Where it grew — soil, climate, local processing style | Uji, Yame, Nishio, Kagoshima |
| Grade | A marketing tier — "ceremonial grade" is not a regulated term anywhere | ceremonial, premium, culinary |
The combinations are the point. "Okumidori from Nishio" is a plant and a place; "Yame matcha" is a place with no plant named; "ceremonial grade" is neither. People regularly compare a cultivar with a region — "Okumidori vs Yame" is a real search — but one is genetics and one is geography, and the same cultivar grown in two regions makes two different teas. That last fact is where matcha gets genuinely interesting, and we come back to it below. For the grade question, our ceremonial grade guide takes it apart properly.
The family tree of Japanese tea
Japanese tea cultivars form one family, and it has a matriarch. Yabukita — selected by the Shizuoka farmer Hikosaburō Sugiyama, who began his seedling experiments in 1908, and registered in 1953 — covers roughly 75% of Japan's tea fields, and it is mother or grandmother to most of the cultivars on this page.
The chart shows confirmed parentage only. Two things to read out of it: almost every modern premium cultivar carries Yabukita blood, usually crossed with something sweeter or greener — and breeding is slow. From cross to registration routinely takes two to three decades; Saemidori was crossed in 1969 and registered in 1990. When a new cultivar arrives, someone started working on it a generation ago.
The matcha cultivars, one by one
Cultivar lots side by side, labelled by name and picking date — Asahi picked May 4, Asatsuyu May 13. Different cultivars bud on different schedules, which is exactly why producers grow more than one.
Yabukita — the baseline
Registered 1953, ~75% of Japanese tea cultivation. Balanced, full, bright — the reference flavour of Japanese tea, and the standard against which every other cultivar gets described. Most matcha blends are built on it. Not glamorous, genuinely versatile. Full Yabukita profile.
Okumidori 奥緑 — the late-budding deep green
Registered 1974 at the Kanaya research station: Yabukita as mother, the landrace Shizuoka Zairai 16 as recorded father — though a 2021 DNA study found the paternity doesn't match, so half its parentage is officially a mystery. "Oku" means late: it buds about a week after Yabukita, and the slower start builds colour and rounded umami with little bitterness. Currently the fastest-growing cultivar search worldwide. We carry it from two regions — Nishio and Kagoshima — plus a Hoshino sencha from the same plant. Full Okumidori matcha profile. The whole shelf: Okumidori collection.
Saemidori 冴え緑 — the clear green
Crossed 1969 at the Makurazaki research station in Kagoshima, registered 1990 as Tea Norin No. 40: Yabukita × Asatsuyu, combining the mother's hardiness with the father's sweetness. The name means "clear green" and describes the cup honestly — vivid colour, sweet, low astringency. A favourite for hand-picked lots; ours come from Nishio and Yame. Full Saemidori profile. The whole shelf: Saemidori collection.
Samidori — the Uji classic
Not to be confused with Saemidori, though half the internet does: Samidori is a much older selection from Uji's own landrace population, the traditional tencha plant of the Kyoto region — and the house cultivar of Marukyu Koyamaen, whose blends we carry. Where the modern research-station cultivars chase colour and yield, Samidori is what Uji koicha tasted like before them. We have a limited single-cultivar Samidori from Nishio — the classical Uji plant grown outside Uji, which is exactly the kind of comparison single-cultivar matcha makes possible.
Seimei — the newest
Japan's youngest premium cultivar: crossed 1992 at Makurazaki, registered 2020. Fushun × Saemidori — so a grandchild of both Yabukita and Asatsuyu — with vivid colour and high amino-acid umami, but better yield and frost resistance than Saemidori. A glimpse of where Japanese breeding is heading. Full Seimei profile.
The ones to watch: Asahi, Asatsuyu, Gokou, Uji Hikari
Four names you will meet on high-end tins. Asahi is the celebrated Uji koicha cultivar — tiny production, serious prices. Asatsuyu is the sweet parent inside Saemidori's genetics, occasionally milled as matcha on its own. Gokou (五香) and Uji Hikari are Uji selections in the same tradition as Samidori. We are tasting single-cultivar lots of several of these for autumn — profiles will follow as the teas land.
Single cultivar or blend — which is better?
Neither. They are two different crafts.
Blending is the older discipline: a house like Marukyu Koyamaen composes matcha from multiple cultivars and fields so that this year's tin tastes like last year's — consistency as an achievement, the blender's palate as the product. Our Marukyu Koyamaen guide covers how that works. Single-cultivar matcha is the newer promise: transparency. One plant, one field, one harvest — you taste what Okumidori actually does, including the vintage variation a blender would smooth away.
A useful cellar has both: a blend as the reliable daily reference, single cultivars as the education. If you drink matcha to understand it, the single-cultivar shelf is where the learning happens.
One cultivar, two regions — the comparison that teaches the most
Because a cultivar is genetically identical wherever it grows (tea cultivars are propagated from cuttings, not seed), growing the same plant in two regions isolates the terroir: same genetics, different soil, climate and shading tradition. Our two Okumidori — Nishio and Kagoshima — are the cleanest side-by-side tasting we can offer: what stays constant is the cultivar, what changes is the place. Region profiles: Uji, Yame, Nishio, Kagoshima.
Taste the difference
Every single-cultivar matcha we carry names the plant, the region and the harvest on its page — Okumidori from two terroirs, hand-picked Saemidori, the classical Uji cultivar Samidori. Milled in small lots, shipped from Munich.
The five at a glance
| Cultivar | Parentage (registered) | In the bowl | Best suited to |
|---|---|---|---|
| Yabukita | Shizuoka selection (1953) | Balanced, full, bright — the reference | Blends, every style |
| Okumidori | Yabukita × Shizuoka Zairai 16 (1974) | Deep jade, rounded umami, low bitterness | Usucha, single-cultivar tasting |
| Saemidori | Yabukita × Asatsuyu (1990) | Sweet, vivid, low astringency | Hand-picked lots, usucha |
| Samidori | Uji landrace selection | The classical Uji koicha character | Koicha, tencha tradition |
| Seimei | Fushun × Saemidori (2020) | Vivid colour, high amino-acid umami | Modern usucha |
How to read the tin
A well-labelled single-cultivar matcha decodes in one line. "Nishio Okumidori, spring harvest" means: the Okumidori plant, grown in Nishio, first flush. Region first or cultivar first varies by producer — the giveaway is that cultivar names are plant names (they attach to no map), while regions are places. If a label offers only "ceremonial grade" and a country, it is telling you neither the plant nor the field; that is not automatically bad tea, but it is a tea that does not want to be looked up. Every matcha in our shop lists cultivar, region and harvest where the producer discloses them — and the single-cultivar shelf is where all three are certain.
FAQ
What is a matcha cultivar?
A cultivar is a registered, named variety of the tea plant Camellia sinensis, propagated from cuttings so every bush is genetically identical. Okumidori, Saemidori, Samidori and Yabukita are cultivars. The cultivar determines the plant's flavour potential; region and processing determine what becomes of it.
Which matcha cultivar is best?
There is no best, only directions: Okumidori for deep colour and rounded umami with low bitterness, Saemidori for sweetness and vivid clarity, Samidori for the classical Uji koicha character, Yabukita for the balanced reference taste. Blends deliberately combine several to hit a house profile.
What does single-cultivar matcha mean?
The tea comes from one named plant variety only, rather than a blend of several. It trades the consistency of blending for transparency — you taste the specific cultivar and its field, including variation between harvests.
Is cultivar the same as ceremonial grade?
No. A cultivar is the plant's registered variety — a fact about genetics. "Ceremonial grade" is an unregulated marketing term with no legal definition anywhere. A tin can name a cultivar and carry any grade label, or neither.
Is Yame a cultivar?
No — Yame is a region in Fukuoka, like Uji in Kyoto or Nishio in Aichi. A "Yame Saemidori" is the Saemidori cultivar grown in Yame. When a label carries only a place name, the cultivar is usually a blend or simply unstated.
How many tea cultivars does Japan have?
Japan has registered well over a hundred tea cultivars, but the matcha shelf runs on a handful: Yabukita as the volume base, and shaded-tea specialists like Okumidori, Saemidori, Samidori, Asahi and Gokou for premium single-cultivar and koicha work.
