How to identify real, high-quality Japanese matcha?
Partager
The matcha market has exploded. And with it, mediocre products packaged with premium vocabulary.
Knowing how to read matcha—even before opening it—is a game-changing skill.
1. Color: the first indicator
Quality matcha is emerald green. Not khaki. Not yellowish. Bright, luminous green, with a depth that varies depending on light exposure.
This color comes from the chlorophyll accumulated during pre-harvest shading (3-4 weeks). The more intense the shading, the higher the chlorophyll, the brighter the color.
Warning sign: brownish-green or dull powder indicates poor quality leaves, late harvest, or faulty storage.
2. Aroma: the olfactory test
Open the tin and breathe. Real matcha smells like freshly cut grass, white flowers, sometimes a light marine note. The aroma is complex, lively.
Matcha that smells like dry hay, a barn, or very little: it's either too old or of inferior grade.
3. Taste: sweetness, umami, absence of bitterness
Prepare it pure, with water at 75°C. No sugar. No milk. Good matcha is naturally sweet. Umami (that savory depth) is present from the first sip.
Bitterness may exist in the background, but it should never dominate. If the matcha is bitter even without being prepared too hot or too concentrated: insufficient quality.
The ultimate test: Prepare the matcha without sugar, at 75°C, with only 1g. If it's pleasant to drink, it's good matcha. If you immediately need to sweeten it to make it palatable, it does not meet ceremonial grade.
4. Origin: Uji and Wazuka make the difference
Geographical origin is not just a marketing argument. Climatic conditions, soil, and local expertise play a direct role in tea quality.
Uji (Kyoto Prefecture) has been the reference region for matcha for centuries. Wazuka, a neighboring village, concentrates some of the best artisanal producers. Matcha traceable to these regions is a guarantee of seriousness.
FAQ
Q: Can we trust "organic" labels on matcha?
A: A Japanese organic label is a good sign, but not enough to guarantee gustatory quality. Matcha can be organic and of poor quality. The two criteria are independent.
Q: Is price a reliable indicator?
A: Partially. Good ceremonial matcha costs at least €25-30 for 30g. But a high price does not guarantee quality—you also need to check the color, aroma, and taste.
Q: Is Origin SUPRAMATCHA certified?
A: Origin Saemidori is grown without pesticides, single-origin Uji. All product information is available on supramatcha.com.
