Usucha first
Usucha, or thin tea, is the most familiar preparation. A smaller amount of matcha is whisked with water to create a light, vivid bowl with a fine surface foam.
It is often the best place to begin because it makes texture, aroma and balance easy to read.
What changes with koicha
Koicha, or thick tea, uses more matcha and less water. The mixture is kneaded rather than whisked into foam, producing a denser bowl with greater concentration.
Not every tea is suited to koicha. The matcha needs enough softness and depth to carry that fuller texture without turning harsh.
A simple rule
Use usucha for daily preparation and to understand a tea's shape. Approach koicha when the matcha has the refinement to hold together beautifully.
The distinction matters, but it does not need to feel ceremonial or stiff. It is simply a question of proportion and intent.
