Saku
Saku is a matcha maker that brings traditional preparation into a more approachable, everyday experience. It preserves the authenticity of hand-whisked matcha while reducing the effort through a simple, gear-driven mechanism that replicates the natural whisking motion.
The product grinds fresh matcha using a built-in stone mill, helping maintain flavor and aroma while avoiding the clumping and texture issues found in common shortcuts like blenders. A replaceable bamboo whisk and intuitive press interaction make the process feel familiar but effortless.
Designed with care for both function and ritual, Saku also considers the details of use. Features like a double-step spout help preserve microfoam while pouring, and a magnetic base keeps the cup stable during preparation.
Overall, Saku turns a traditionally labor-intensive process into a calm, seamless routine without losing the essence of how matcha is meant to be made.
Process:
This project started by studying traditional matcha making and identifying the gap between authenticity and convenience. The concept focused on translating hand whisking into a simple mechanical system. Through CAD and iterative prototyping, the gear-driven whisking and stone mill were developed to create a more intuitive and consistent experience.
Learning Outcomes:
Learned how to translate a traditional, hands-on process into a simple mechanical system without losing its core experience. Developed stronger skills in mechanism design, prototyping, and refining user interaction. Also gained experience balancing function, form, and material decisions to create a product that feels both intuitive and intentional.
