Overview
Hario built this Coffee Mill as a slim hand grinder: turning the crank spins a ceramic burr set that drops grounds into a clear lower bottle. A knob sets coarseness, and the handle lifts off so the mill stores in a narrow space.
Ceramic burrs and a slim body make this a practical way to grind beans fresh at home. Hand cranking means a slower routine, and with no stated grind steps, dialing in a brew method takes trial and error.
Who it's for
Small households brewing a cup or two at a time get fresh grounds from a mill that tucks into a narrow cabinet gap. People who grind large batches daily will tire of the crank.
Pros and cons
- Ceramic burrs do not rust
- No odor carried into grounds
- Clear bottle shows how much is ground
- Handle removes for compact storage
- Hand cranking takes time and effort
- Number of grind settings not listed
- Capacity suits small batches only
Performance notes
Grind consistency comes from the ceramic burr pair and how firmly the knob holds its setting. Cranking speed sets how long a dose takes, and the transparent bottle lets you stop at the amount you need.
