CHOOSE YOUR GRIND

According to your equipment

Practical guide • 6 min read


Grinding is the most neglected variable at home yet the most decisive. Too coarse, water passes too quickly and the coffee lacks body. Too fine, extraction blocks and bitterness dominates. Here’s how to find the right setting for your equipment.

THE PRINCIPLE

SLOWER = FINER

The logic behind the adjustment


Each extraction method has its own contact time between water and coffee. The shorter this time, the finer the grind must be to maximize extraction. The longer it is, the coarser it must be to avoid over-extraction.

★ GOLDEN RULE

Espresso (25–30 sec) = very fine grind. Filter (2–4 min) = medium grind. French Press / Cold Brew (4–12 h) = coarse grind.

BY EQUIPMENT

METHOD-BY-METHOD GUIDE

Each device, its setting


Espresso machine

The grind must offer enough resistance so that water takes 25 to 30 seconds to pass through the puck. If extraction is too fast, grind finer. If too slow or blocked, grind coarser.

GRIND SIZE

Very fine

TIME

25–30 sec

DOSE

17–19g

V60 & pour-over filter

Aim for a full extraction in 2 min 30 to 3 min. Too fine a grind will slow the flow and make the coffee bitter. Too coarse, water passes too quickly and the coffee will be flat.

GRIND SIZE

Medium

TOTAL TIME

2:30 – 3:00

RATIO

1:15 (e.g. 20g/300ml)

French Press

The full 4-minute brew requires a coarse grind. Too fine, particles pass through the filter and the coffee becomes cloudy and bitter.

GRIND SIZE

Coarse

BREWING

4 minutes

RATIO

1:12 (e.g. 25g/300ml)

Moka (Italian coffee maker)

The Moka works at low pressure (1–2 bars). A fine grind like for espresso risks blocking extraction and creating dangerous pressure. Aim for a grind between fine and medium.

GRIND SIZE

Fine–Medium

FILLING

Full basket

HEAT

Medium heat

Cold Brew

Cold brew requires the coarsest grind of all methods. Cold brewing lasts 12 hours: a fine grind would produce over-extracted and bitter coffee, even when cold.

GRIND SIZE

Very coarse

BREWING

12–18 h refrigerated

RATIO

1:8 (e.g. 80g/640ml)

The investment that changes everything


Conical burrs

Less heat generated, precise adjustment, ideal for filter and espresso. The baristas' choice.
