Manual coffee grinder HARIO CMHN-4 — weight 0.9 kg, black/transparent/wood finish

HARIO CMHN-4 is a manual coffee grinder designed for home use, weighing 0.9 kg with a compact footprint (width 208 mm, depth 105 mm). The unit combines black, transparent and wood-coloured elements and features a hand crank and a ceramic burr mechanism that preserves coffee aroma by grinding beans without pre-heating. The adjustable grind setting covers a range from fine to coarse to support multiple brewing styles while the canister design stores grounds in the same airtight container used for grinding.

Advantages

The ceramic burr produces consistent particle size distribution that helps extract balanced flavour across drip, pour-over and immersion methods. The mixed-material construction—glass, wood and metal accents—offers durability and stable operation during manual grinding. A removable lid reduces bean spillage and the canister doubles as a storage jar for freshly ground coffee, reducing handling and exposure to air.

Suitable for

• Drip coffee makers
• Pour-over brewers (V60, Chemex and similar)
• Immersion methods (French press, AeroPress in coarse to medium settings)
• Home users who prefer manual grinding and compact equipment

How to use

Place whole coffee beans into the top chamber, secure the lid and set the grind adjustment to the desired level for your brewing method. Rotate the hand crank with steady, even strokes until all beans are ground and collected in the canister. Remove the canister to access freshly ground coffee; if necessary, re-seat the canister and lightly tap to settle the grounds before removing. Clean the burr and canister periodically following manufacturer guidance to maintain performance.

Usage recommendations

For best results, use freshly roasted whole beans and adjust the grind size incrementally to match your brewer and taste. Grind only the amount needed for immediate brewing to preserve aroma. Clean the grinder regularly to avoid oil and residue buildup; avoid washing wooden parts with excessive water.
