Hario Mini Mill: Review, Grind Settings, and 4 Brew Methods It Handles

The Hario Mini Mill is the most recommended entry-level hand grinder for one reason: ceramic conical burrs at under $40. Ceramic burrs do not rust, do not heat the grounds, and produce consistent particle size. For anyone starting a home setup, it is the correct first grinder.

This guide covers the specs, the 4 grind settings by brew method, and who should upgrade past it.

Hario Mini Mill Specs at a Glance

Hario Mini Mill Grind Settings by Brew Method

The Hario Mini Mill uses a numbered click system , tighter (lower number) for finer grind, looser (higher number) for coarser. French press: clicks 20 to 22. The coarsest useful setting for immersion brewing. Produces a chunky grind that slows extraction and reduces sediment in the cup. Drip coffee: clicks 14 to 16. Medium grind for flat-bottom and cone basket auto drip machines. Pour over (V60): clicks 10 to 12. Medium-fine for 2:30 to 3:30 total brew time. AeroPress: clicks 8 to 10 for a filter-style brew, or clicks 6 to 8 for an espresso-style short press. These are starting points , adjust one click at a time based on brew time and taste. See our pour over guide for how grind size affects total brew time.

Ceramic burrs at this price point. Most grinders under $40 use steel burrs that rust if exposed to moisture. The ceramic burrs do not rust, stay cooler than steel, and hold their edge longer at this price point. Numbered clicks make it easy to return to a known setting after adjusting. The 24g hopper handles a standard dose without reloading. Browse our premium whole bean coffee , the Hario Mini Mill works across all three Blackout roast levels. See our hand grinder guide for how the Mini Mill compares to the full hand grinder category.

The acrylic body is the main weakness. It is not impact-resistant , drop it and the catch cup or hopper cracks. The burr has minor wobble at this price point, which slightly affects grind uniformity at fine settings. It is not suitable for espresso. Grind speed is slow compared to metal-burr hand grinders , a 20g dose takes 90 to 120 seconds. Natural upgrades: Timemore C2 (stainless burrs, faster, more durable) or 1Zpresso JX (better fine-grind range). Upgrade when the body breaks, when you need espresso range, or when grind speed is daily friction.

FAQ: Hario Mini Mill

Yes , it is one of the most popular hand grinders for V60 pour over specifically. Clicks 10 to 12 hit a 2:30 to 3:30 brew time at 1:15 ratio. The ceramic burrs produce clean, consistent particle size that suits the clarity-focused pour over method. One click finer if too fast (sour). One click coarser if too slow (bitter). Light roast Smooth Finish pairs best. Browse our premium whole bean coffee to order.

Yes. Set clicks 20 to 22 for a coarse French press grind. At this setting it produces a chunky, even grind for a 4-minute steep. Ceramic burrs are most consistent at coarse settings , uniformity dips slightly at fine. See our French press method guide for the full steep parameters.

A 20g dose at medium-fine (pour over) takes 90 to 120 seconds. At coarse (French press), 60 to 90 seconds. Ceramic is slower than stainless , the tradeoff for rust resistance and cooler grinding. For speed, the Timemore C2 grinds the same dose in 45 to 60 seconds. See our hand grinder guide for how the Hario Mini Mill fits the broader hand grinder category.

Unscrew the catch cup, remove the adjustment nut and burr assembly, and brush all surfaces with a dry brush. The ceramic burrs are dishwasher-safe , rinse and fully dry before reassembling. The acrylic body and catch cup can be rinsed with water. Never leave any part wet , moisture degrades the adjustment mechanism. Clean weekly for daily use. It disassembles fully without tools. See our coffee storage guide for keeping whole beans fresh between grinds.

The Timemore C2 for filter brewing or the 1Zpresso JX for better fine-grind range. The Timemore C2 uses stainless steel burrs, grinds faster, and has a more durable body at a similar price. The 1Zpresso JX steps up to higher burr precision and extends the fine-grind range toward light espresso. Both produce more uniform grinds at medium-fine settings.
