The Hario Olive Wood Ceramic Coffee Mill is a hand-crank manual grinder built around conical ceramic burrs, with an olive wood handle grip and grounds container, glossy white ceramic hopper cover, and stainless steel accents. It holds up to 30 g of coffee beans per grind session and is assembled in Japan to strict quality standards.
The Hario Olive Wood Ceramic Coffee Mill uses conical ceramic burrs to shave coffee beans rather than crack or smash them. Ceramic transfers less heat than metal during grinding, which matters because heat generated at the burr face can volatilize aromatic compounds before the coffee ever reaches your brewer. The result is a grind that is more uniform in particle size and more consistent from session to session.
The grind setting on this mill can be adjusted and then locked in for repeat use, so once you dial in the right coarseness for your pour-over or French press, you do not have to re-tune it every morning. For home brewers who rotate between a small number of recipes, a repeatable setting removes one variable from an already precise process.
The grounds container and handle grip are turned from olive wood, a dense hardwood with a warm, distinctive grain that improves in appearance with use. Structural components (the spring, screw, handle shaft, locking screw, and outer cover) are stainless steel. Burrs and hopper cover are ceramic. Silicone rubber o-rings at three points seal the grind path and keep grounds where they belong. Anti-slip urethane stickers on the base keep the mill stable on a countertop while grinding.

The Hario Olive Wood Ceramic Coffee Mill suits home brewers who want a manual grinder that produces a consistent grind without electricity, and who value materials (olive wood and ceramic) that are as much about craft as function. The 30 g capacity is well matched to one or two cups brewed by pour-over, French press, or similar methods.
This mill is not suited to high-volume grinding: at 30 g per session it is not practical for brewing for a crowd or for batch-grinding multiple days of coffee at once. It is a hand-crank grinder, which means it is not a fit for anyone who needs motorized, hands-free grinding.
The Hario Olive Wood Ceramic Coffee Mill has an adjustable conical ceramic burr set that can be set and locked for repeat use. The grind setting range by number of steps or clicks is not specified; the adjustable mechanism is designed to cover the coarseness levels used in common manual brewing methods.
The Hario Olive Wood Ceramic Coffee Mill holds up to 30 g of whole coffee beans per session, which is enough for one to two cups depending on brew ratio and method.
The ceramic conical burrs in the Hario Olive Wood Ceramic Coffee Mill shave beans rather than cracking or smashing them as a blade grinder does. Ceramic transfers less heat than metal during grinding, which helps preserve aromatic compounds, and the burr geometry produces a more uniform particle size for more consistent extraction.
The Hario Olive Wood Ceramic Coffee Mill is a fully manual, hand-crank grinder. The stainless steel handle is turned by hand to drive the ceramic burrs; no power outlet or batteries are needed.
The Hario Olive Wood Ceramic Coffee Mill is assembled in Japan to strict quality control standards.
