Introduction
Not all matcha is created equal. Between a cheap supermarket matcha and a Japanese ceremonial-grade matcha, there is a world of difference in taste, nutrients, and benefits. The problem? Brand marketing often makes it difficult to tell good matcha from bad. Misleading labels, attractive packaging, vague claims — how can you tell?
In this guide, we reveal the 5 objective and easily verifiable criteria for recognising quality matcha. After reading this article, you will never be fooled again.
1. Colour: A Vibrant Green
The first and most immediate criterion is colour. Quality matcha displays a vivid, luminous, intense green, sometimes tending towards jade green. This is the sign of high chlorophyll content, produced when tea plants are shaded before harvest. The more vibrant the colour, the richer the matcha is in nutrients.
Poor quality matcha has a yellow-green, olive, or dull colour. This may indicate several problems: tea leaves not shaded before harvest, oxidation from poor storage, blending with lower quality leaves, or simply culinary matcha sold as ceremonial. Test: open the packet and observe the powder in natural light. Good matcha should be as vivid as freshly cut grass.
2. Smell: Fresh and Vegetal
Bring your nose close to the matcha and breathe deeply. Good matcha releases a fresh, vegetal, slightly sweet aroma. You can detect grassy notes, sometimes a hint of sea air reminiscent of nori seaweed. It is a living, pleasant, distinctive fragrance.
Poor quality matcha will smell like dry hay or dust, or have no smell at all. If the matcha smells rancid or sour, it has probably oxidised and lost its properties. Aroma is a reliable indicator of freshness and harvest quality.
3. Texture: Fine as Talc
The fineness of the grind is a determining criterion. Authentic matcha is ground on granite stone mills at very slow speed to prevent heating and oxidation. The result: an exceptionally fine powder of around 5 to 10 microns, as fine as talc or eyeshadow.
The finger test: Take a small amount of matcha between your thumb and index finger and rub gently. Quality matcha glides silkily with no graininess. It leaves a green trace on your skin like a pigment. Coarse matcha will feel gritty, a sign of fast industrial grinding that produces larger particles and partial oxidation.
4. Taste: Umami and Sweetness
Taste is the ultimate criterion. Ceremonial-grade matcha offers a complex and balanced flavour profile: a pronounced umami flavour (that famous fifth taste, both round and savoury), followed by natural sweetness and a light vegetal finish. Bitterness is present but subtle, never aggressive.
Poor matcha will be excessively bitter and astringent, with a hay or dusty flavour. It will completely lack the umami roundness that makes great matcha magical. If you have to add sugar or milk to make it drinkable, the matcha probably is not good enough. A quality ceremonial matcha is enjoyed pure, with just water.
5. Origin: Japan First
Geographical origin is a fundamental criterion. Authentic matcha comes from Japan, specifically from traditional tea-growing regions. Japanese expertise in matcha is unrivalled: plant shading techniques, leaf selection (only the youngest leaves are used), and grinding on granite stone mills.
The key Japanese regions: Uji (Kyoto) — the most prestigious region, historic birthplace of Japanese matcha; Nishio (Aichi) — Japan's largest matcha producer by volume; Kagoshima — subtropical climate producing naturally sweet, low-bitterness matcha; Shizuoka — a major tea region known for quality green teas.
Bonus: Price as an Indicator
Quality ceremonial matcha costs between 25 and 50 euros for 30g. This price reflects harvest quality, slow grinding, and artisanal craftsmanship. If you find "ceremonial matcha" at 10 euros per 100g, be suspicious — it is probably culinary grade, blended, or inferior quality. However, do not confuse expensive with good: some pricey matchas trade on packaging rather than quality. Rely on the 5 criteria above rather than price alone.
