How to use a chasen to prepare matcha?

A chasen is the bamboo whisk used to disperse matcha in water and create a fine foam. Technique matters more than force: a quick wrist movement works better than slow, heavy whisking.

In short: soften the chasen in warm water, sift the matcha, add water and whisk quickly in a W or M motion for about 15–20 seconds.

What does a chasen do?

Matcha does not dissolve like sugar. Tiny tea particles remain suspended in water. The chasen helps distribute them evenly and incorporate air.

Prepare the whisk

Soak the bamboo tips in warm water for a few tens of seconds before use. This makes them more flexible. Avoid soaking the entire handle.

Step by step

Sift 1.5–2 g of matcha into a wide bowl.
Add 60–80 ml of water at about 70–80 °C.
Mix gently at first.
Speed up using the wrist.
Use a W or M motion rather than slow circles.
Finish lightly near the surface.

Use your wrist, not your arm

Keep the elbow and shoulder relatively stable. Short, quick movement is more efficient and gentler on the bamboo.

Why is there no foam?

Possible causes include unsifted powder, too much water, a narrow bowl, slow circular movement, a damaged whisk or an unsuitable water-to-matcha ratio.

Foam is not the only sign of a good preparation; even dispersion and pleasant texture matter more.

Cleaning and drying

Rinse immediately with clean water, avoid dish soap, shake off excess water and let the chasen dry fully in a ventilated place. A chasen holder can help preserve its shape.

Chasen, electric frother or shaker?

A chasen gives fine texture and control. An electric frother is quick but can create larger bubbles. A shaker is practical for cold drinks but gives a different texture.
