What Is Matcha? The Green Tea You Drink Whole
On this page
Matcha is everywhere now — in lattes, ice cream and cakes around the world. But the bright green powder whisked into a bowl in Japan is a very particular thing, quite different from ordinary green tea, and understanding what it actually is changes how you taste it. In short: with most tea you steep the leaves and throw them away. With matcha, you drink the whole leaf.
Powdered — but that's not the point
Yes, matcha is a powder, but the powder is the result of something more important. Matcha is made by grinding specially grown and processed green tea leaves so finely that they dissolve into water rather than being steeped and strained out. Because you consume the entire leaf, you get far more of its colour, flavour and nutrients than you would from an infusion. That is the whole idea, and everything else follows from it.
Grown in the shade
The first secret of matcha is shade. For several weeks before harvest, the tea plants are covered to block much of the sunlight. Starved of full sun, the leaves respond by producing more chlorophyll — which gives matcha its vivid green — and, crucially, more of an amino acid called L-theanine, the source of matcha's savoury, brothy sweetness known as umami. Shading is why good matcha tastes smooth and sweet rather than harsh and grassy.
From tencha leaf to stone-ground powder
After shading, the leaves are picked, steamed to stop oxidation, dried, and stripped of stems and veins. In this state the leaf is called tencha. Only then is the tencha ground into matcha — traditionally on slow-turning granite stone mills, which take up to an hour to produce just a small amount and keep the powder cool enough to protect its aroma. The slowness is not inefficiency; it is what makes the texture silky and the colour bright.
Where the best comes from
Matcha is grown in several parts of Japan, but two names carry the most prestige. Uji, near Kyoto, is the historic heart of fine matcha, its reputation stretching back centuries. Nishio, in Aichi, is another major producer known for quiet, consistent quality. Origin, like grade, is part of what you are paying for.
Ceremonial vs culinary
You will see matcha sold as two broad types. Ceremonial-grade matcha is made from the youngest, finest leaves and is meant to be whisked with hot water and drunk on its own; it is smoother, sweeter and more expensive. Culinary-grade matcha is stronger and more astringent, made to hold its own against milk and sugar in lattes and baking. Neither is 'better' — they are made for different jobs. Using pricey ceremonial matcha in a sugary cake wastes its delicacy.
A drink with a spiritual past
Matcha's story in Japan begins with Zen. Powdered tea was brought from China by Buddhist monks, who valued it for keeping the mind alert and calm during long meditation. From the monasteries it entered the tea ceremony and the life of the samurai elite, carrying with it an air of discipline and refinement it has never quite lost.
How to enjoy it
- Sift, then whisk. Push the powder through a small sieve to break up clumps, add hot (not boiling) water, and whisk briskly with a bamboo chasen until frothy.
- Mind the water temperature. Around 70–80°C is ideal; boiling water scorches matcha and turns it bitter.
- Buy small, store cold. Matcha fades fast once opened — keep it sealed, cool and away from light, and use it within a few weeks.
- Match the grade to the use. Ceremonial to drink; culinary for lattes and cooking.
So matcha is not simply 'green tea powder.' It is shade-grown leaf, steamed and dried into tencha, then stone-ground so fine that you drink the plant entire — colour, umami, caffeine and all. Once you know that, the bright green bowl in front of you becomes a lot more interesting than a trendy latte.
