How to grind your coffee right for each brew method
The same bag of coffee gives a completely different result depending on grind size — a practical guide for espresso, V60, and French press.

The same bag of coffee can taste completely different depending on how coarse or fine the grind is — it’s probably the most underrated variable in brewing coffee at home.
Why grind size determines everything
Grind size determines how quickly water passes through the coffee. A finer grind means more surface area and a slower, stronger extraction. A coarser grind means less surface area and a faster, milder extraction.
Espresso: like powdered sugar
A very fine grind, so water under pressure takes 25–30 seconds to pass through. Too coarse here means a weak, sour espresso.
V60 and filter: like coarse sugar
A medium-fine grind that lets water flow freely over a total brew time of 2:30–3:00.
French press: like coarse salt
A coarse grind is essential here — anything finer slips through the metal filter and ends up as sediment in your cup.
The rule that matters most
Change one variable at a time. If the coffee tastes sour, grind finer. If it tastes bitter, grind coarser. Keep notes until you find the spot that suits your taste.
