Compare two teas
Side by side across seven dimensions. There is no verdict and no winner — the purpose is to understand the difference, not to be told which to buy.
Why these two get confused
Koicha and usucha grades of matcha. The distinction is whether the powder can be drunk at four times normal concentration without bitterness, which is what the grade certifies.
TeaHQ has written about this pair
There is no official matcha grading system, and the terms everyone uses were invented by sellers. What actually varies is measurable, and this compares the two ends of it.
- What the grade certifies
- Matcha usucha grade: That it is good enough for the ordinary whisked preparation.Matcha koicha grade: That the powder can be drunk at four times normal concentration without bitterness.
- Concentration
- Matcha usucha grade: Around 2 g to 70 ml, whisked to a light foam.Matcha koicha grade: Around 4 g to 40 ml, kneaded into a paste.
- Leaf
- Matcha usucha grade: First or second harvest, shaded.Matcha koicha grade: First harvest from the oldest shaded bushes.
- Price
- Matcha usucha grade: High, but this is what most good matcha is.Matcha koicha grade: Highest in the category by a wide margin.
- Where the fake grades come in
- Matcha usucha grade: Same. 'Culinary' usually means unshaded ground green tea, which is a different product.Matcha koicha grade: No official term exists. 'Ceremonial' is a seller’s word.
In summary: Buy on colour, harvest date and price consistency rather than on the word on the tin. If the seller cannot say when it was picked or whether it was shaded, the grade name is decoration.

Nothing above is a recommendation. The last row describes the drinker each tea suits, using each tea’s own authored fields and the same sentence structure for both, so neither can be framed as the safe choice.
