When it comes to making the perfect cup of matcha, one of the most important tools is the chasen, the traditional bamboo whisk. The right chasen will help you to achieve the perfect microfoam but also just make sure that your matcha ritual and the whisking process is more enjoyeable.
What Is a Chasen?
A chasen is a handcrafted bamboo whisk carved from a single piece of bamboo and split into dozens of fine tines. In fact they are always handcrafted, even the cheaper ones because they cannot be mass-produced by machines.
These delicate tines are designed to break up clumps of matcha powder and create a smooth, creamy foam. Unlike electric frothers, a traditional bamboo chasen is made specifically for matcha.
Standard Chasen vs. Shin Chasen: What’s the Difference?
Standard Chasen
Most shops will sell you the “standard” shape which is the easiest and cheapest one to produce. These whisks typically have:
-
Tines that curve sharply near the tip
-
Small loops at the ends
-
A heavier feel
-
Thicker prongs
This design works well for beginners because the whisk is thicker and sturdier, so it doesn't break as easily. However, it often requires more effort and creates larger bubbles rather than fine foam.
Shin Chasen
The Shin chasen (真, meaning “formal” or “true”) is known for its elegant shape and lighter feel. It is favored by many traditional tea schools and experienced matcha drinkers.
Key features of a Shin chasen include:
-
More gradual, natural curves
-
No tightly looped tips
-
Thinner, more flexible tines
-
Lighter overall weight
-
Better balance in the hand
Because the tines are finer and more responsive, a Shin chasen moves more easily through the tea. This allows you to introduce more air with less force, resulting in a finer, creamier foam. The lighter handle and balanced shape make whisking feel natural and effortless.
How to Get the Best Results with Your Chasen
To make the most of your Shin chasen:
-
Soak it briefly in warm water before use
-
Whisk in a fast “W” or “M” motion
-
Avoid pressing hard against the bowl
-
Rinse gently after use (no soap)
-
Let it air dry naturally
With proper care, a high-quality bamboo whisk will last longer and perform better.
The Right Tool Makes All the Difference
While a standard chasen can do the job, a Shin chasen elevates the entire experience. It gives you better foam, smoother texture, and a more enjoyable ritual.
If you have been struggling to create microfoam with your chasen, it might be because of the type of chasen you are using.
