Ceremonial grade matcha is powdered green tea that originated in Jingshan, China, where whisked tea was born, and became widely popular in Japan. It is made from first-harvest tencha leaf, grown in the shade for 20 to 30 days and stone-milled to particles under 10 micrometres. It is drunk on its own, whisked with water, and differs from culinary grade in its jade green, its sweet umami and the absence of bitterness on the attack.

The technical definition that matters
Ceremonial grade matcha is powdered first-harvest tencha (ichibancha), grown in shade for at least three weeks and ground between granite stones to particles smaller than ten micrometres. That definition is not poetic: it is technical, and it separates one product from another by variables you can measure in a laboratory.
The word matcha (抹茶) joins the characters matsu (to grind, to rub) and cha (tea). In the Japanese tradition it means only the tea prepared for the tea ceremony, the Chanoyu, and made by this specific process. What many Western brands call «ceremonial grade matcha» does not meet those conditions: it can be industrially milled green tea, with no shading, made from second or third harvest leaf.
Verified figure
According to Japan’s Ministry of Agriculture, Forestry and Fisheries, national tencha production, the raw material of real matcha, almost tripled between 2012 and 2023, going from 1,430 to 4,176 tonnes. Only Japanese tencha made by the traditional process can become ceremonial matcha.
From field to cup: the whole process
Understanding how ceremonial matcha is made is understanding why it costs what it costs. Every step has direct consequences for taste, colour and composition.
1. Choosing the cultivar
Not every variety of Camellia sinensis makes matcha of comparable quality. In Uji the most prized cultivars are Okumidori, Samidori, Ujihikari and Asahi. Okumidori is valued for the creamy texture it gives when whisked. Saemidori, also widespread in Yame and Kagoshima, stands out for its bright green and pronounced sweetness. These cultivars have been selected over decades specifically to perform well under shade.
2. Shading (ōishita or tana)
Three to four weeks before the first spring harvest, between late April and early May, the tencha fields are covered with shading structures. In the traditional ōishita method the plants are protected by layers of rice straw and woven bamboo, cutting sunlight by 90 to 95 per cent. The modern tana method uses black synthetic netting, cheaper but with different results in the cup.
Less light triggers a metabolic change: unable to photosynthesise efficiently, the leaf stops converting L-theanine into catechins. The result is a build-up of L-theanine (responsible for umami and sweetness) and chlorophyll (responsible for the deep jade green). Catechins, which in quantity give astringency and bitterness, stay low.
The shading that changes everything
«The ōishita technique already appears in the writings of seventeenth-century Portuguese missionaries. It is thought to have begun by accident: growers covered the plants to protect new shoots from late spring frosts.» The Japanese Tea Hub, drawing on historical sources from the Azuchi-Momoyama period
Shading does more than change the flavour. It also shapes the leaf itself: in low light the plant makes larger, thinner leaves with fewer veins, which makes it easier to separate the leaf flesh (aracha) by hand to produce tencha. Sencha leaves, grown in full sun, are stiffer and more fibrous, and unsuitable for quality matcha.
What tencha is and why it matters
Tencha (点茶 or 挽き茶) is the half-processed tea that precedes matcha. Once picked, always at the first spring harvest, the leaves are steamed for about thirty seconds to stop oxidation. They are then dried in specialised ovens at around two hundred degrees, and the stems and veins are removed by hand. What is left are fine flakes of leaf flesh: tencha.
This is radically different from sencha, which is kneaded and rolled. Tencha is dried without rubbing or rolling, which leaves its cell structure intact. The consequence is direct: when it is milled, the surface of each particle exposes the leaf cells without heat damage from excessive friction, which preserves the volatile aromas.
Only matcha made from tencha has the L-theanine, chlorophyll and EGCG profile characteristic of ceremonial grade. Green tea simply ground to a powder, with no shading and none of the specific tencha processing, does not have the same sensory characteristics or the same composition, whatever the label says.
Stone milling
Tencha is ground between granite stones (ishi-usu, 石臼). Each pair of stones, about thirty centimetres across, turns at ten to twenty revolutions a minute, a deliberately slow speed, and produces thirty to forty grams of matcha an hour. At that rate almost no heat builds up, which preserves the volatile aromas of the tencha.
Modern industry uses impact mills or metal ball mills that can turn out several kilos an hour. The result is coarser (particles above ten micrometres), more bitter from the heat of friction, and gritty in the mouth. It is technically tencha powder, but it is not the same product as the stone-ground version.
For ceremonial grade matcha used in Chanoyu practice, the tea masters of the Urasenke and Omotesenke schools, the two principal schools of the tea ceremony, require stone-ground matcha. That is not a marketing requirement: it is a standard of practice centuries old.
Ceremonial vs culinary: the real difference
| Feature | Ceremonial grade | Culinary grade |
|---|---|---|
| Raw material | First-harvest tencha (ichibancha) | Second or third harvest tencha, or ground green tea |
| Shading | 3 to 4 weeks, at least 90% less light | Reduced or none |
| Milling | Granite mills, <10 micrometres | Industrial mills, 10 to 40 micrometres |
| Colour | Vivid jade green (L*a*b*: a* strongly positive) | Yellowish or dull green |
| Taste | Pronounced umami, sweetness, minimal astringency | Astringent, bitter, flat |
| L-theanine | High (25 to 45 mg/g) | Low (5 to 15 mg/g) |
| Use | Water only, tea ceremony | Baking, lattes, smoothies |
| Guide price (30 g) | €18 to €60 depending on origin and quality | €4 to €12 |
How to recognise genuine matcha
Without laboratory equipment, these are the practical signs of a real ceremonial matcha:
- Colour: deep jade green, almost bright. Yellow, brown or dull tones mean the shading was insufficient, or the leaf came from a late harvest.
- Dry aroma: fresh and grassy, with seaweed notes, umami, a light floral touch. Never dusty, never hay, never dry cut grass.
- Texture: extremely fine to the touch. If you feel grains when you rub it between your fingers, the milling was industrial.
- Foam: whisked with a chasen it forms a dense, persistent foam of small bubbles. Lower quality matcha gives a few large bubbles that vanish quickly.
- Taste: immediate sweetness and umami, with no aggressive astringency on the first sip. Bitterness, if it comes at all, should arrive at the end and be brief.
- Grower information: a real ceremonial matcha always states the region (Uji, Nishio, Yame, Kagoshima), the cultivar and the harvest date. The absence of that information is a warning sign.
The practical conclusion
Real ceremonial matcha is a precision agricultural product, made by a process that has not changed substantially in five centuries. Its cost is not arbitrary: it reflects shading put up by hand, ichibancha picked by hand, and slow grinding between stones. The «ceremonial matcha» sold at four euros for a hundred grams is not ceremonial matcha.
To come into this with some judgement, start with the classic Uji cultivars or with Kagoshima Saemidori. Both have well documented profiles and growers you can check.
Frequently asked questions
What does «ceremonial grade» mean?
Matcha (抹茶) means ground tea. «Ceremonial» is not a regulated category in any market: any manufacturer can print it on a tin. In the trade it means matcha good enough to drink on its own in the tea ceremony, which is to say first-harvest tencha, shaded and stone milled. That is why you read the product specification rather than the label.
What is ceremonial grade matcha for?
For drinking on its own, whisked with water, as usucha (thin) or koicha (thick). It is not meant for baking or for lattes: milk and sugar cover exactly what you are paying for, the umami and the sweetness. Culinary grade is what that is for, at roughly half the price.
How does it differ from culinary grade?
In the harvest (first against second or third), the shading (20 to 30 days against little or none), the milling (stone, below 10 micrometres, against industrial mills at 10 to 40) and the result in the bowl: jade green and sweet umami against dull green and bitterness.
How can you tell whether a matcha is genuinely ceremonial?
There are five signs that need no laboratory: jade green in daylight, a lively young-pea aroma, dissolving without lumps in cold water, a microbubble foam that holds for more than a minute, and a sweet rather than bitter first impact.
How much does ceremonial grade matcha cost?
The price on the tin misleads, because sizes run from 20 to 100 grams. What compares is the cost per cup: of those we have tasted, the cheapest works out at €0.42 and the dearest at €2.80, at the standard 2 g dose.
