Which Cultivars Become Matcha — and Why Yabukita Doesn't

Yabukita is by far the most widely planted tea cultivar in Japan. It is also poorly suited to tencha.

What Yabukita is good at

Bred in Shizuoka, Yabukita excels as a sencha cultivar.

The problem for tencha is color. Its leaves carry a yellowish cast, and it does not develop the deep green that shading is supposed to produce. Since shaded cultivation aims for a dark, saturated leaf, that is a significant disadvantage.

The Uji cultivars

Matcha and gyokuro rely on cultivars selected over generations from native stock around Uji, chosen specifically for how they respond to shade.

Samidori The most widely planted cultivar for hand-picked tencha in Uji. It offers a long picking window and good yield. The leaf holds moisture well and the stem is firm, which makes harvesting easier. The flavor is described as deep and full, with a refined, unaggressive umami.

Asahi Its new shoots emerge bright green, thin and large. Considered particularly strong for tencha, and often used for competition-grade tea.

Gokou Takes to shading especially well and develops the distinctive covered aroma readily. Also used for gyokuro.

Others include Ujihikari, Tenmyo, and Ujimidori.

Cultivar names rarely appear on packaging

Unlike wine grapes, matcha seldom states its cultivar.

Blending multiple cultivars to build a consistent flavor is standard practice. Single-cultivar products exist and usually say so, since it is a selling point.

In sweetened products, even less so

Sweetened matcha almost never lists cultivar.

Origin is more likely to appear, and it does carry information. Uji is the historic center of tencha production, which implies cultivars suited to shaded cultivation.

Absence of the detail is not a red flag — its presence is simply one more data point.
