Matcha tea whisk

First Use

Soak the chasen for a few minutes in 80°C water: the bamboo will soften, and the central curl will unfurl. You can then whisk hot water (using the same motion as when preparing matcha) to finish relaxing the bamboo. Your chasen is now ready!

Rinsing After Every Use

Simply rinse it with lukewarm water.

You can also whisk clear water in your bowl to dislodge any remaining residue.

Never use soap (bamboo is porous and would absorb the taste) nor a dishwasher.

Drying

A chasen that remains damp at the base will grow mold.

Use a Kusenaoshi (porcelain whisk holder):

It helps maintain the rounded shape of the tines and ensures optimal airflow.

Without a Kusenaoshi: Leave it to air dry with the tines facing upward (ideally tilted in a bowl).

When Should You Replace It?

The chasen is made from natural materials and is not eternal. Its longevity depends on two main factors: how often you use it and the care taken after each use, especially during rinsing and drying.

It is time to replace it if you notice:

Loss of tines: If the bamboo bristles start to break or fray.

Presence of mold: If you see even the slightest trace of mold on the bamboo, replace it immediately.
