The Hario Mini-Slim+ is a compact, hand-crank ceramic burr coffee grinder designed for home use and travel, with a 24 g ground-coffee capacity. Conical ceramic burrs grind by shaving rather than cracking the bean, producing a more consistent particle size across grind settings. This model is an upgrade from the original Mini-Slim, featuring a redesigned handle and shaft coupling for improved grip and traction during grinding.
The Mini-Slim+ uses conical ceramic burrs, which shave coffee beans rather than cracking them the way blade grinders do. Because ceramic transfers less heat than metal during grinding, the grounds reach the catch bottle without the brief thermal spike that can dull volatile aromatics. The result is a more uniform particle distribution that holds its setting across repeated uses, so a grind dialed in for a morning pour-over stays where it was set the evening before.
At 150 mm wide, 72 mm deep, and 220 mm tall, the Mini-Slim+ fits in a bag pocket or a small kitchen drawer without taking up counter space. The 24 g ground-coffee capacity is sized for one to two cups per session, making it a practical companion for travel, office use, or any situation where a full-size grinder is impractical. The stainless steel shaft and handle, combined with nylon adjustment components, keep the overall weight low while maintaining structural rigidity through the grind cycle.
Grind coarseness is set via the adjustment nut and can be returned to a saved position for consistent results session to session. The redesigned shaft coupling introduced in the Mini-Slim+ adds traction at the connection between handle and burr shaft, reducing slip during grinding and making the adjustment mechanism more positive to turn. For a first hand grinder, this repeatability removes one variable from the brewing process while the user is still learning other parameters.

The Mini-Slim+ suits home brewers and travelers who want fresh-ground coffee without a powered grinder, and who are grinding one to two cups at a time. Its straightforward adjustment mechanism and repeatable settings make it a practical first hand grinder for someone new to manual brewing.
The Mini-Slim+ is not suited to grinding for multiple people in a single session, as its 24 g capacity is designed for small individual batches. It is a hand-crank grinder and requires no power source, so it is not a substitute for an electric grinder where speed or high-volume output is needed.
The Hario Mini-Slim+ has a ground-coffee capacity of 24 g, which is enough for one to two cups depending on brew method and dose. It is designed for individual or small-batch grinding rather than preparing coffee for several people at once.
The Hario Mini-Slim+ is a manual hand-crank grinder and requires no batteries or electrical connection. Grinding is done entirely by turning the handle, making it suitable for travel, camping, or any setting without a power source.
The Hario Mini-Slim+ uses conical ceramic burrs. Ceramic transfers less heat than metal during grinding, and the conical shaving action produces a more uniform particle size than blade grinders, which crack beans unevenly. More consistent grounds give the brewer more control over extraction.
Yes. The Mini-Slim+ has an adjustable grind nut that can be set to a preferred coarseness and returned to that position for consistent results across sessions. This makes it straightforward to dial in a setting for a specific brew method and repeat it.
The Hario Mini-Slim+ features a redesigned handle and shaft coupling compared to the original Mini-Slim. The updated coupling provides better traction between the handle and the burr shaft, reducing slip during grinding and making the mechanism more positive to operate.
