Matcha Cultivars Explained: Yabukita, Samidori, Asahi & Okumidori

Every matcha comes from the same species, Camellia sinensis — but so does every wine grape belong to the same species, Vitis vinifera, and nobody would call Cabernet Sauvignon and Pinot Noir interchangeable. Tea works the same way. Within the species, dozens of cultivars (bred or selected varieties) exist, each with its own growth habit, chlorophyll level, amino acid profile, and flavor tendency.

Most matcha you'll find is a blend of several cultivars, chosen to balance color, sweetness, and cost across harvests. But once you're already buying good ceremonial-grade matcha, cultivar is where the flavor differences get genuinely interesting.

What Is a Cultivar, and Why Does It Matter for Matcha?

A cultivar is a specific variety of tea plant, propagated by cutting rather than seed to preserve its exact traits. For matcha, the traits that matter most are: how much chlorophyll and L-theanine the leaf accumulates under shade, how tender and small the new buds are, how the plant responds to the cold, and how early or late in the season it's ready to harvest. Two cultivars grown in the same field, shaded for the same number of days, can still produce noticeably different matcha.

Yabukita

Yabukita is the workhorse of Japanese tea — it accounts for roughly 70 to 75 percent of all tea acreage in Japan, across every category, not just matcha. It's hardy, reliable, and easy to cultivate, which is exactly why it's so dominant. For matcha specifically, Yabukita is used less often at the very top tier — it's better suited to sencha — but it shows up frequently in blended and culinary-grade matcha, where it contributes a balanced, slightly grassy backbone.

Samidori

Samidori ("light green") is one of the most prized cultivars for ceremonial-grade matcha, especially around Uji. It's prized for its vivid green color, mellow sweetness, and notably low bitterness even without heavy dilution. When you see a premium single-cultivar matcha marketed on flavor alone, there's a good chance it's Samidori or a Samidori-heavy blend.

Asahi

Asahi is a historic Uji cultivar known for intense umami and unusually deep color — but it's delicate and harder to cultivate at scale, which keeps it rarer and pricier. It tends to show up in small-batch, premium ceremonial blends rather than everyday matcha.

Okumidori

Okumidori ("deep green, late") buds later in the season than most cultivars and is valued for exceptional, stable color retention — the "deep green" is in the name for a reason. Because visual vibrancy sells, Okumidori is a popular component in blends aimed at boosting a matcha's color without necessarily boosting its price.

Other Cultivars You May See on Premium Labels

• Saemidori: A cross prized for sweetness and low astringency, often used in high-end sencha and matcha alike.
• Gokou: Traditionally associated with tencha and gyokuro production, valued for rich umami.
• Uji-hikari: A newer Uji-bred cultivar developed specifically with matcha quality in mind.

None of these are common outside single-cultivar, connoisseur-tier products — but if you see one named on a label, it signals a producer being unusually specific about what's in the tin.

Single-Cultivar vs Blended Matcha

Most matcha — especially culinary grade — is a deliberate blend of multiple cultivars. Blending lets a producer smooth out year-to-year variation in any single field and hit a consistent color and flavor target every harvest. Single-cultivar ("tan'ichi," 単一) matcha is rarer and pricier, but it shows a distinct, un-blended character, roughly analogous to a single-origin coffee or a single-varietal wine: less "balanced" by design, more expressive of one specific plant.

Does Cultivar Matter More Than Grade or Region?

Honestly — for most everyday drinking, no. Freshness, shading duration, and harvest timing (see our piece on why "ceremonial grade" isn't a regulated standard) will affect what's in your cup far more than which cultivar it came from. Cultivar knowledge becomes most useful once you're already buying good, fresh, well-sourced matcha and want to explore the finer differences between one premium tin and another — the way a wine drinker moves from "red or white" to noticing the grape.
