Who it fits
Good fit for
You should choose this grinder if you value portability and clean coffee flavor. The small 24-gram capacity is perfect for single-serve methods like pour-over or AeroPress. The ceramic burrs reduce heat transfer, preserving delicate aromas. Its slim footprint fits easily in drawers or travel bags. If you drink one cup at a time and want a reliable, compact tool, this mill delivers consistent results without taking up much counter space.
Who should skip it
Skip this option if you need to grind large batches for a family or office. The 24-gram limit means you must refill frequently for multiple cups. Manual grinding requires physical effort, so you might prefer an electric model if you want speed. If you need a digital scale or timer built in, this basic mill lacks those features. It is also not suitable for those who prefer blade grinding or need a motorized solution for convenience.
Verdict: The Hario Mini-Slim Plus is a compact, manual grinder best suited for single-cup brewing and travel. Its ceramic burrs and small capacity make it a practical choice for portable coffee preparation.
Key specs explained for this grinder
Burr Material: Ceramic
Ceramic burrs transfer less heat to the coffee beans during grinding compared to metal alternatives. This helps preserve the delicate flavor notes in your beans. You get a consistent grind without risking heat damage. This is ideal if you care about taste purity. It is a practical choice for those who want to avoid the metallic taste some metal burrs can impart.
Grinding Mechanism: Conical burr
Conical burrs crush and shave beans between a rotating cone and a stationary ring. This design generally produces a more uniform particle size than flat burrs. A consistent grind leads to better extraction in your brew. You will see fewer fines or boulders in your grounds. This mechanism is preferred for precise control over your coffee strength and clarity.
Bean Capacity: 24g
This grinder holds up to 24 grams of coffee beans per batch. This capacity is suitable for grinding a single cup or a small double shot. It is not designed for large batches or multiple users at once. You should measure your beans carefully to avoid overflow. This limit makes it a compact tool for individual drinkers rather than households with heavy coffee consumption.
Weight: 10.6 ounces
Weighing only 10.6 ounces, this unit is very lightweight. Its low weight makes it easy to carry in a bag or backpack. You can take it on trips without adding significant bulk. It is simple to hold and crank without fatigue. This portability is a key benefit for travelers who want fresh grounds away from home.

The shaft coupling is newly designed to improve traction. This means you get better grip and control while turning the handle. The bean capacity is listed at 24 grams.

Before You Buy This Grinder
Owning the Hario Mini-Slim Plus requires a few extra steps to get the best results. Since it holds only 24 grams of beans, you must grind small batches. This means you need a scale to measure your dose accurately before grinding. The ceramic burrs are durable but brittle. You should avoid dropping the unit or grinding frozen beans, as this can chip the ceramic. Cleanliness is also key. Use the included brush regularly to remove fine grounds from the burrs and catch cup. Stale coffee oils can affect flavor over time. This grinder fits well if you already own a manual brewer like a French press or pour-over setup. It does not replace electric grinders for large households. If you travel often or have limited counter space, this compact design is a strong choice. Just remember that manual grinding takes more time and effort than motorized options.
Check before you buy
- Verify you have a scale for 24g doses.
- Check if your brewer fits the catch cup size.
- Ensure you have a brush for cleaning ceramic burrs.
- Confirm you prefer manual grinding over electric speed.
