Understanding matcha
Matcha is not powdered green tea. It is a specific leaf — grown under shade, dried flat without rolling, stripped of stem and vein, and milled slowly on stone — and every confusing thing about it follows from that. This path meets the leaf before the powder, then the two preparations that are genuinely different drinks.
Who this is for
Someone who drinks matcha lattes, or has bought a tin and a whisk, and wants to know what the thing actually is.
What you should come away with
You will be able to say what separates matcha from ground sencha, why the price range is so wide, and why usucha and koicha are not two strengths of one thing.
Leg 1 · The leaf before it is powder
A shading gradient ending somewhere unexpected. Tencha is matcha's raw material and almost nobody outside the trade has tasted it: shaded leaf, steamed and dried without any rolling at all, so the step every other Japanese green tea is defined by is deliberately skipped. Meeting it is the fastest way to stop thinking of matcha as green tea that has been ground.
Starting point. Everything after this is measured against it.
The practical middle of Japanese green tea: most of gyokuro’s savoury depth at a fraction of the price, and far less punishing to brew than gyokuro’s near-cold water and enormous leaf quantity.
Why this step follows
Most of the shaded savoury depth, at a fraction of the price and without the near-cold brewing.
Thick and almost broth-like, with very little astringency and a sweetness that arrives before anything else. The clearest teaching case in tea for what umami actually means in a cup.
Why this step follows
Same shaded leaf with the rolling step removed. Gyokuro is rolled and behaves like a tea; tencha is dried flat and brittle, brews pale and thin, and only makes sense once you know it is a raw material rather than a finished cup.
Extraordinarily sweet and savoury, and much gentler than the matcha made from it — because steeping leaves the bitter fraction largely in the leaf while grinding puts all of it in the bowl.
Leg 2 · The two preparations
Thin and thick are not dilutions of one drink. They use different grades, opposite whisking motions, different caddies and different etiquette, and koicha is the one the ceremony is built around. Usucha is where anyone should learn the stroke.
Starting point. Everything after this is measured against it.
Intensely savoury and thick-textured, with a bitterness that is part of the design rather than a fault. Lower grades tip from savoury into flatly bitter, which is the main reason people conclude they dislike it.
Why this step follows
Thin to thick. Usucha is whisked to a foam with water enough to dilute any roughness; koicha is kneaded to a paste at three or four times the concentration and shows everything the powder has.
Thick, sweet and almost entirely without bitterness — which is the point of the grade, since ordinary matcha at this concentration would be undrinkable.
Read alongside
- Whisking matcha: a suspension, not an infusion
Nothing is extracted and nothing is strained out, so the usual brewing variables barely apply. What matters is breaking the powder up, keeping it suspended and getting air into it.
- What matcha should cost, and what you are paying for
Matcha spans roughly two orders of magnitude in price, and almost all of the difference is decided before the leaf reaches the mill. Here is where each cost sits, and which of them a drinker can actually taste.
- Choosing a matcha without a grading system to lean on
There is no regulated matcha grading, no certifying body and no agreed vocabulary. What there is: a small set of things a seller either tells you or does not, and each omission means something.
- Ceremonial grade, and the other words nobody defines
A group of terms on tea packaging look like classifications and are not: no body defines them, no audit checks them, and any seller may use any of them. Knowing which words are in this group, and what to look at instead, is most of label literacy.
