How Matcha Is Made: From Tencha to an Ultra-Fine Powder

Published: Updated:

Is matcha simply green tea ground into powder?

No: matcha begins with tencha, not ordinary sencha. Here is the path from shading and steaming to finishing and milling.

Why is matcha made from tencha, not sencha?

According to the Japanese green tea industry definition, tencha is made from tea leaves that are shaded for about two to three weeks before harvest, then steamed and dried without rolling, often in a tencha drying furnace. Matcha is tencha that has been ground into a fine powder using a stone mill or a method with comparable function.

The key point is “without rolling.” Sencha is generally steamed, rolled while being dried, and then brewed by infusion in hot water. Tencha is dried without rolling, leaving the leaf in a flatter form that is intended to become powder later.

If you would like a little more background, our short glossary entry on tencha is a helpful place to continue.

What does shading do to the taste?

For tencha, tea plants are covered before harvest to reduce the amount of light reaching the leaves. The book gives a shading rate of about 95–98%. This tends to slow the conversion of theanine into catechins, which is one reason shaded tea often has more umami and gentler bitterness.

Traditional honzu covering uses reed screens and rice straw, while kanreisha uses synthetic fabric. Covering began as frost protection and later developed into a cultivation technique for shaping color and taste. These describe tencha cultivation, not specifications for ICHIZEN's raw tea.

Treat this as a tendency: leaf condition, refining, storage, and preparation also change the final taste.

Sencha and tencha, compared by process

Point Sencha Tencha
Cultivation Often grown without shading Shaded for about two to three weeks before harvest
Heat treatment Steamed Steamed
Drying Rolled while dried Dried without rolling
How it is drunk Infused in hot water Dispersed as a fine powder in water or milk

Seen this way, matcha is not simply “sencha made into powder.” It is designed differently from the field onward. For a wider comparison, you may also enjoy our guide to matcha vs green tea.

What happens after tencha is dried?

In traditional Uji tea gardens, naturally trained branches have been hand-picked by bending and snapping off the tender shoot, a method called ori-zumi. The steamed leaves are dried without rolling in a tencha furnace whose lower level reaches 180–200°C or more. This is a general account of the traditional process.

Before dried tencha becomes matcha, it is cut, sifted, winnowed, dried again, and sorted. This finishing process removes stems and leaf veins so the powder can have a smoother texture, clearer aroma, and more even appearance.

Then the refined tencha is milled into a fine powder. Traditionally, finished tencha is ground with a stone mill, but the definition also includes grinding methods with functions comparable to a stone mill.

ICHIZEN’s matcha is made from Kyoto Uji tea selected and refined by Wakimoto Jokoen, a fourth-generation green-tea wholesaler in Ide-cho, Kyoto. It is not stone-milled; it is machine-milled into an ultra-fine, uniform powder.

Matcha does not truly dissolve—it disperses

Matcha is not completely soluble; fine tea-leaf particles remain dispersed in the liquid. Some settling is natural, so stir or swirl the drink gently before drinking.

Knowing the process makes choosing matcha easier

Price and taste reflect cultivation, tencha production, refining, milling, and storage. For usucha, consider aroma and smoothness; for lattes and sweets, consider color and how flavor carries through milk or sugar. Our article on why matcha can be expensive explains it calmly.

In short: matcha begins with tencha

Matcha is not sencha that has simply been powdered. It begins with shaded tea leaves that are steamed, dried without rolling, refined, and milled into a fine powder.

Knowing the process makes the sources of its flavor easier to understand.

FAQ

Is matcha made from sencha?

No. Matcha is made from tencha: tea leaves that are shaded before harvest, steamed, and dried without rolling. Sencha is usually rolled while dried and brewed by infusion.

Does matcha completely dissolve in water?

No. Matcha does not fully dissolve; fine tea-leaf particles are dispersed in the liquid. Some settling over time is natural, so stir or swirl before drinking.

Is only stone-milled tea called matcha?

Traditionally, finished tencha is ground with a stone mill, but the definition also includes comparable grinding methods. ICHIZEN uses machine milling for a fine powder.

Is shaded matcha always low in bitterness?

Shading tends to support umami and soften bitterness by slowing changes from theanine to catechins. The final taste still depends on the tea, refining, storage, and preparation.
