Grind size controls how fast water pulls flavor from coffee. Too fine and the cup turns bitter. Too coarse and it tastes sour and thin. Matching the grind to your brew method is one of the easiest ways to improve your coffee.
The chart
- Extra coarse: cold brew and some long steeps. Looks like coarse sea salt.
- Coarse: French press. Looks like kosher salt.
- Medium-coarse: some pour-over cones and flat-bottom drippers.
- Medium: automatic drip makers and most pour-over. Looks like regular sand.
- Medium-fine: moka pot and siphon. A little finer than sand.
- Fine: espresso. Close to table salt or finer.
- Extra fine: Turkish coffee. Powder, like flour.
Why grind size matters
Smaller particles have more surface area, so water extracts flavor faster. Longer brew methods need coarser coffee so extraction does not run too far. Short, pressurized methods need finer coffee so enough flavor comes out in the time available.
Grind by brew method
French press
Use coarse. Fine grounds slip through the mesh and keep extracting after you press. See the French press ratio for amounts. Equipment: French Press Coffee Maker, 34oz.
Pour-over and drip
Use medium. If the water drains very slowly and the coffee is bitter, go slightly coarser. If it drains fast and tastes sour, go slightly finer. See the V60 guide.
Moka pot
Use medium-fine and do not tamp. See how to use a moka pot. Equipment: Aluminum Mocha Pot.
Espresso
Use fine. Espresso is the least forgiving method, because small grind changes shift the flavor a lot.
Turkish coffee
Use extra fine. Read how to make Turkish coffee.
Cold brew
Use extra coarse and steep long. Our cold brew guide has the ratios.
Fix your coffee by adjusting the grind
- Bitter, harsh or dry: the grind is too fine. Go coarser.
- Sour, thin or salty: the grind is too coarse. Go finer.
- Muddy with silt in the cup: too many fines. Use a more even grinder or a coarser setting.
Change one thing at a time and taste after each change.
Which grinder to use
A grinder that can hold a consistent size matters more than a high price. Hand grinders such as the Hand Crank Coffee Grinder and electric options like the Stainless Steel Electric Coffee Grinder are covered in grinders under $50. For fine Turkish grinds, look at the Turkish Manual Coffee Grinder. Product pages list the adjustment range, so check them for your brew method.
Grind fresh
Coffee goes stale quickly once ground. Grind right before brewing and store beans in an airtight container away from heat and light. Clean your grinder regularly: how to clean a coffee grinder.
FAQ
Can I use one grind for everything?
A medium grind works for drip and pour-over, but other methods need a different size.
Does pre-ground coffee work?
It works if the grind matches your method, but it loses flavor faster.
What grind is best for beginners?
Start with a French press and a coarse grind, or a drip maker and a medium grind.
