Hario Mini Slim+ Manual Coffee Grinder – Ceramic Burrs, 24 g

Want to grind your coffee just before brewing without making room for an electric grinder? The Hario Mini Slim+ manual coffee grinder uses adjustable ceramic burrs and a hand crank in a compact, slim design. It’s a practical option for small batches at home, at work, or when traveling.

The transparent grounds container lets you see your progress, and the handle comes off for storage. There’s no motor or outlet to plan around, but you do provide the effort. Add your beans, turn the handle, and grind what you need for your next brew.

Who is the Mini Slim+ for?

Choose it if you’re starting with whole-bean coffee, brewing for one or two people, or want a small manual grinder to take along. It’s better suited to modest batches than grinding coffee for a crowd. Hand grinding takes time, so an electric grinder may be a better fit if speed is your priority.

How much coffee does it hold?

The listed grounds capacity is 24 g, and Hario describes it as suitable for 1–2 cups. Your actual number of servings depends on your coffee dose and recipe. That 24 g specification refers to the grounds container, not a separately verified bean-hopper capacity.

Can I adjust the grind size?

Yes. Turn the grind-adjustment knob to change the burr setting. Follow the manufacturer’s adjustment instructions and start with a setting suited to your brewing method. If the result isn’t what you want, change the grind while keeping your coffee and water amounts steady so you can tell what helped.

What are ceramic burrs?

Burrs are the two grinding surfaces that break the beans into smaller particles. The Mini Slim+ has ceramic inner and outer burrs, rather than a spinning blade. Adjusting the burr setting gives you a way to change the grind for your recipe.

What changed in the Plus model?

The Mini Slim+ features a reinforced hexagonal adapter. It also has a removable handle and a slim body for storage. Those are practical details for a grinder you may pack away between brews.

Do the container markings replace a scale?

The transparent container has measurement markings to help you judge the amount collected. For a repeatable recipe, weigh your coffee: different beans and grind sizes can occupy different amounts of space.
