Usucha vs Koicha: What Is the Difference?
Sep 30, 2026
Usucha and koicha are not simply “weak matcha” and “strong matcha.” They are two distinct traditional preparations with different ratios, textures, whisking methods and roles in chanoyu.
Usucha means thin tea. Koicha means thick tea.
The basic difference
| Usucha | Koicha | |
|---|---|---|
| Matcha | about 1.5–2 g | about 4 g |
| Water | about 60–70 ml | about 30 ml |
| Texture | light, fluid | dense, creamy, almost sauce-like |
| Whisking | vigorous back-and-forth motion | slow mixing/kneading motion |
| Foam | often fine foam | not prepared for foam |
| Tea choice | many matcha work well | requires very smooth, low-astringency matcha |
What is usucha?
Usucha is the style most people encounter when they drink a bowl of matcha today.
Ippodo’s basic method uses 2 g matcha with 60 ml water at 80°C, whisked vigorously for about 15 seconds. Marukyu Koyamaen gives a similar everyday guideline of roughly 1.5 g with 70 ml water, adjusting temperature and concentration to preference.
Usucha is fluid enough to drink easily and is commonly whisked until the surface develops fine bubbles or foam.
What is koicha?
Koicha uses much more matcha and much less water. Ippodo’s basic koicha guideline is 4 g matcha with 30 ml water at 80°C.
Instead of whisking rapidly, the chasen is moved slowly to mix the matcha into a glossy, thick consistency.
A good koicha should not feel like dry powder suspended in too little water. It should be dense but smooth and integrated.
Why does koicha need better matcha?
Because the concentration is so high, bitterness and astringency are magnified.
Marukyu Koyamaen states that while all of its matcha can be used for usucha, only its higher-quality products are recommended for koicha. That is a much more useful quality clue than an undefined label such as “ceremonial grade.”
If a matcha is rough when prepared as usucha, koicha will usually make that roughness even more obvious.
Does koicha have foam?
No, not in the way usucha does.
Koicha is mixed slowly rather than vigorously aerated. The goal is a smooth, lustrous, thick tea—not a layer of foam.
This is why “more foam = better matcha” is not a universal rule.
Is koicha just concentrated usucha?
Technically the ingredients are still only matcha and water, but culturally and sensorially koicha is more than a stronger version.
The texture changes the entire experience. Aromas feel denser, umami becomes more pronounced and the tea coats the mouth rather than behaving like a thin drink.
What role do they play in chanoyu?
In formal tea gatherings, koicha traditionally carries particular importance. Urasenke materials distinguish separate procedures for usucha and koicha, and formal gatherings may include both.
Traditionally, koicha may be shared from one bowl among guests. Modern Urasenke also uses kakufukudate, in which koicha is prepared in individual servings, so “koicha is always shared” would be too absolute.
Usucha is generally served as individual bowls and is also the form used in many introductory tea-ceremony experiences.
Can beginners make koicha?
Yes. You do not need a formal tea room to understand the difference.
Use a matcha specifically recommended for koicha, sift it carefully, use a scale if possible and mix slowly. The texture is unfamiliar at first, so small adjustments are normal.
Which should you try first?
Start with usucha. It is more forgiving, uses less matcha and gives you a clearer sense of whisking, water temperature and the tea’s basic flavor.
Once you have a smooth matcha that you enjoy, try it as koicha if the producer recommends that use.
A useful rule
Usucha shows you how a matcha drinks. Koicha shows you how refined it really is.
That does not mean koicha is automatically “better.” It means the preparation leaves fewer places for harshness to hide.
