Not All Japanese Green Tea Is Matcha

One Plant, Many Teas Every tea below comes from Camellia sinensis. What differs is when the leaf is picked, whether the bush was shaded, and how the leaf is treated after. Japanese green teas are almost all steamed rather than pan-fired — a Japanese innovation that locks in the vivid green colour and grassy, marine flavour that distinguishes them from Chinese greens.

The Five You'll Actually Meet Sencha is the everyday standard: full-sun leaves, steamed and rolled, bright and slightly astringent — around three-quarters of Japan's production. Gyokuro is the luxury: bushes shaded for about three weeks before harvest, which raises the amino acid theanine and produces a deep, sweet, almost broth-like cup. Matcha comes from similarly shaded leaves, dried flat and stone-ground to powder, so you drink the leaf rather than an infusion. Hojicha is sencha roasted until brown — nutty, low in caffeine, and what many families drink in the evening or serve to children. Genmaicha is tea blended with roasted brown rice, originally a way to make expensive leaf go further, now loved on its own terms.

Where It Grows Shizuoka, on the Pacific slopes below Mount Fuji, produces the largest share of Japan's tea, with hillside fields you can ride straight past on the shinkansen. Uji, south of Kyoto, is the historic prestige region and the heart of matcha and gyokuro. Kagoshima in southern Kyushu has grown fast on volcanic soil and an early harvest. Yame in Fukuoka is celebrated for gyokuro specifically.

The Water Temperature Rule The most common mistake is boiling water. Sencha wants around 70–80°C; gyokuro as low as 50–60°C. Boiling water scalds the leaf and pulls out bitterness — which is why the same tea can taste sublime at a tea house and harsh at home.

Shade Is the Variable That Matters The single biggest divide in Japanese green tea is whether the plants were shaded before picking. Covering the bushes for a few weeks before harvest starves them of light, which pushes up the amino acid theanine and suppresses the catechins that produce bitterness. The result is sweeter, rounder, deeply savoury tea.

That is what separates gyokuro and the leaf that becomes matcha from ordinary sencha, which is grown in full sun. It is also why shaded teas cost several times more: the yield drops and the labour rises. Tasting a gyokuro next to a sencha is the fastest education available in Japanese tea, and the difference is not subtle.

The Rest of the Family Sencha is the everyday tea and the bulk of production. Bancha is the later, coarser harvest — cheaper, lighter and entirely respectable. Hōjicha is roasted, which drives off much of the caffeine and produces a toasty brown infusion that is what many households actually drink in the evening. Genmaicha adds roasted rice. Kukicha is made from stems.

Matcha is different in kind rather than degree: shaded leaf, stems and veins removed, stone-ground to powder, and whisked into water rather than infused, so you consume the leaf itself. That is why it delivers more caffeine and more of everything else than a steeped tea.

Brewing It Without Ruining It The most common mistake is boiling water. Japanese green tea wants water well below boiling — cooler for higher grades, cooler again for gyokuro, which is brewed at a temperature that feels wrong until you taste the result. Too hot and you extract the bitterness the shading was there to suppress.

Steeping time is short, and good leaf is meant to be infused several times, with each infusion tasting different. Throwing leaf away after one pot is the other common waste, and any decent tea house will demonstrate the sequence if you ask.

The Regions Shizuoka produces the largest volume, and its landscape of terraced tea slopes under Mount Fuji is the image most people have of Japanese tea. Uji, south of Kyoto, is the historic prestige region and the centre of matcha production. Kagoshima in the far south is now a major producer with an earlier harvest thanks to the climate, and Sayama in Saitama has a reputation for a distinctly full-bodied style.
