How to Grind Coffee: Grind Sizes for Every Brewing Method

Grind size controls how quickly water moves through coffee and how much flavor it extracts. A grind that is too fine can taste bitter and heavy, while a grind that is too coarse can taste thin and sour. Use this guide as a practical starting point.

Espresso needs a very fine, sand-like grind. Moka coffee uses a fine grind, but it should not be as fine as espresso. AeroPress is flexible: try finer grounds for a short recipe and medium grounds for a longer steep. V60 and other pour-over methods usually work with medium grounds, similar to table sugar.

French press needs a coarse grind because the coffee steeps for several minutes. Cold brew generally benefits from a very coarse grind, which is easier to filter and produces a clean, gentle drink. If water runs too quickly through a pour-over, go finer. If brewing is slow and the cup tastes dry, go coarser.

Change one variable at a time. Sour, sharp and empty flavors often mean under-extraction: grind finer or extend the brew. Bitter, dry flavors suggest over-extraction: grind coarser. Freshly ground coffee is ideal, and a burr grinder makes more even particles than a blade grinder. Our burr versus blade grinder guide explains the difference.

Starting points: espresso very fine, moka fine, AeroPress fine to medium, V60 medium, French press coarse and cold brew very coarse. These are not rigid rules. Record your recipes and adjust according to taste.
