Controllable compression and rotational speed

Control the compression between the plates to balance milling efficiency and matcha fineness.

The millstone seated in the milling chamber

Swappable and upgradable millstones

Easily replace or upgrade millstones over time. When compared to a traditional stone mill, the milling surface damage is the greatest liability, we have modularized it.

For centuries matcha was ground fresh shortly before consumption

Matcha is a surface area to volume ratio explosion. At 10x finer than the average espresso grind, nutrients rapidly degrade, what is fresh and sweet turns bitter and harsh, and color fades.

The industrial-scale matcha production enabled premilled matcha to be enjoyed by nearly everyone, everywhere. But it created a set of modern compromises, most importantly around matcha freshness. Sanko Usu One aims to fill that gap allowing anyone, anywhere to mill matcha fresh.
