What Is Matcha?

Matcha is green tea leaf, shade-grown and stone-ground into a fine powder, then whisked directly into water or milk. You drink the whole leaf, not an infusion of it. That's the entire definition. Everything else is detail.

Why matcha isn't just "green tea powder"

Regular green tea is leaves steeped in water and then discarded. You're drinking what dissolved out of them. Matcha skips that step entirely. The leaf itself is ground fine enough to suspend in liquid, so what ends up in your cup is the tea, not an extract of it.

That single difference is why matcha tastes and behaves differently from a cup of sencha or a green tea bag. You're getting the chlorophyll, the fiber, the full amino acid profile. A bag of green tea gives up maybe a third of what's actually in the leaf before you throw it away. Matcha gives up all of it, because none of it gets thrown away.

There's a separate mix-up worth clearing up too: "green tea powder" and matcha aren't automatically the same thing. A lot of what's sold as green tea powder is just regular sencha, sun-grown or barely shaded, ground down after the fact as a cheaper stand-in for real matcha. It looks similar in the tin, a fine green powder, but it skipped the part that actually defines matcha: weeks of shading before harvest. That shading is what builds up L-theanine and softens the catechins responsible for bitterness. Skip it, and what you're left with tastes sharper, more grassy, and noticeably more astringent than proper matcha, closer to a bitter cup of steeped green tea ground into powder form than to the smooth, umami-forward cup matcha is supposed to be. If a "matcha" tastes harsh and lawn-like, there's a decent chance it's this, sun-grown leaf sold under the matcha name without ever having earned it.

Where it comes from

Matcha starts as tencha, tea leaves grown under shade cloth for three to four weeks before harvest. Shading does two things: it spikes chlorophyll (hence the color) and it slows the plant's conversion of amino acids into catechins, which is why shaded leaf tastes rounder and less bitter than sun-grown leaf.

After harvest, the leaves are steamed to stop oxidation, dried, de-veined, and stone-ground. Traditional stone mills produce about 30-40 grams an hour. That's not a marketing detail, it's a real production constraint, and it's a big part of why matcha costs what it does compared to loose-leaf tea.

Japan's major matcha-producing regions each show up differently in the cup. Uji, Kyoto is the historical center and tends toward umami-forward, rounder profiles. Kagoshima, in the south, has volcanic soil and a warmer climate, producing leaf that's often sweeter and brighter. Our OG Matcha is Yabukita cultivar from Chiran, Kagoshima. There's no universal "best" region, they just produce different characters, the same way Bordeaux and Barossa both make serious wine that tastes nothing alike.

What it actually tastes like

Good matcha is vegetal, sweet, and umami-forward, with a clean jade green color. The bitterness people associate with matcha is almost always a quality or preparation problem, not an inherent trait of the tea. Coarse grind, low-grade leaf, or water that's too hot (matcha scalds easily above 80°C) will all push a cup toward bitter and grassy. Properly shaded, properly ground matcha from a good harvest shouldn't taste like lawn clippings.

Matcha grades, briefly

You'll see matcha marketed as culinary, premium, or ceremonial grade. In practice, "ceremonial" gets used as a pricing label more often than an accurate one. We've written a full breakdown of what actually separates the grades, and why that label gets misused as often as it's earned.

What's in a cup

A 2g serving of our OG Matcha contains 43mg of caffeine, lab-tested, not estimated. Saemidori Matcha runs higher, 54.6mg per 2g serving. That's alongside L-theanine, an amino acid that's largely responsible for matcha's different feel compared to coffee. We've written more on the caffeine numbers specifically, if that's what brought you here.

How people drink it

Traditionally, matcha is whisked with just hot water using a bamboo chasen, either thin (usucha) or thick (koicha) depending on the ratio of powder to water. Outside Japan, most people encounter it as a latte, hot or iced, matcha whisked into a small amount of water first and then combined with milk. Both are legitimate ways to drink it. Neither is more "correct" than the other, they're just different preparations for different occasions.
