Traditional hand-crafted bamboo chasen with 80 tines — the go-to tool for smooth, lump-free matcha preparation. Suited for everyday café and restaurant use. Easy to clean, lightweight, and compatible with standard matcha bowls.
A bamboo chasen — matcha whisk — is not interchangeable with a standard kitchen tool. The specific material, construction and tine count of a chasen are directly responsible for the quality of the matcha preparation: the consistency of the emulsification, the fineness of the foam, and the absence of lumps in the final cup. We supply traditional handcrafted bamboo chasen for daily cafe use — built to the specifications that Japanese and Chinese tea ceremonies have refined over five centuries.
Bamboo is the only practical material for a chasen. Its natural combination of flexibility and tensile strength allows tines to be carved to a consistent thinness — thin enough to move through matcha suspension quickly and generate foam — while retaining enough spring to return to shape after each use without cracking or deforming. Synthetic alternatives lack the micro-surface texture of bamboo that assists emulsification; metal alternatives are too stiff and damage the ceramic bowl. Traditional chasen-making regions in Japan and China have worked exclusively with bamboo for this reason, and the tool has not changed in any fundamental way in five hundred years.
Tine count determines how quickly and effectively the whisk can break down matcha powder in water and create a stable foam. 80 tines is the accepted standard for everyday professional use: sufficient to produce a smooth, consistent result with the W-motion technique in 15 to 20 seconds, and robust enough to withstand multiple uses per day over an extended service life. For cafes preparing standard matcha lattes at volume, this is the tine count that balances performance and durability at a practical cost per unit.
A bamboo chasen will last significantly longer with proper care. After each use, rinse it immediately under warm water — never hot — while gently pressing the tines outward to release any matcha residue. Do not use soap, which strips the natural oils from the bamboo. Shake off excess water and air dry upright or on a chasen stand, with the tines pointing upward to allow them to dry in their natural shape. Never store a wet chasen in a closed container or lay it flat, as this encourages mould and causes the tines to deform. With correct care, a standard chasen will serve a moderate-volume cafe for two to four weeks before replacement is needed.
