Grind Size for Pour Over: Start Here (2026)

Quick answer

Start with a medium-fine grind for pour over, then adjust one notch at a time. Stumptown Coffee Roasters recommends medium-fine for most pour-over methods and suggests going slightly finer when coffee tastes sour or weak.

Pour over is a gravity brew: water falls through the coffee bed instead of being pushed by pressure. Basic Barista explains that this makes grind size closely tied to flow, so small changes can alter both drawdown and what you taste in the cup.

• Baseline grind: medium-fine, like table salt.
• Baseline recipe: 20g coffee and 320g water, or any ratio you can repeat.
• Baseline target: a steady drawdown and a cup that does not taste sharp or ashy.

What you'll need

You need repeatable tools more than fancy tools: an adjustable burr grinder, a scale, a timer, beans, filtered water, and your brewer. An adjustable burr grinder makes changes repeatable; if yours jumps around too much, see our pour-over grinder picks.

• Adjustable burr grinder: burrs let you make deliberate setting changes; blade grinders produce irregular particles, as Stumptown notes.
• Scale: keep coffee and water fixed with a coffee scale for repeatable brews.
• Timer: use drawdown time as a clue, not a strict scorecard.
• Beans and filtered water: use the same coffee and water while you dial in so the comparison stays useful.

How to dial in grind size for pour over

Dial in pour-over grind by holding the recipe steady, brewing once, tasting honestly, and changing only the grind. Do not change dose, water, temperature, and pouring style all at once. That turns breakfast into a guessing game, and nobody needs that before coffee.

Step 1: Set a medium-fine baseline

Set your grinder so the coffee looks like table salt: small, even grains, not powdery flour and not chunky beach sand. If your grinder has numbers, ignore anyone else’s exact click count. Their burrs, beans, and brewer are not sitting on your counter.

Step 2: Measure the same recipe every time

Pick one recipe and keep it locked for a few brews. A 20g coffee to 320g water setup is easy math and gives you a clear baseline. Start your timer when water first touches the grounds.

Step 3: Brew and observe the drawdown

Pour steadily and watch how the bed drains. If water rushes through like it found a trap door, the grind may be too coarse. If it sits there sulking and the filter clogs, the grind may be too fine or dusty.

Step 4: Adjust one increment at a time

If the cup tastes sour, sharp, or weak, go one step finer. If it tastes bitter, dry, smoky, or muddy, go one step coarser. Brew again with the same recipe. Stop when the cup tastes balanced to you.

Common mistakes

The biggest mistake is changing too many things at once. If you grind finer, pour harder, use hotter water, and switch beans, you will not know what helped. Keep the morning boring until the cup tastes good, then play around.

• Chasing exact grinder clicks — use other people’s settings as rough clues, not gospel.
• Ignoring fines — powdery dust can clog filters and make the cup taste muddy.
• Changing recipe and grind together — fix one thing, brew again, then judge.
• Calling time the winner — taste matters more than hitting a perfect stopwatch number.

Troubleshooting

Troubleshoot by symptom first: sour usually points finer, bitter usually points coarser, and muddy often points to too many fines or a clogged filter. Coffee ad Astra explains that very fine grinding can increase clumping, filter clogging, and muddier cups.

Sour, sharp, or weak

Move one step finer and brew the same recipe again. If it still tastes thin, check that you used enough coffee and did not pour so fast that the water sprinted through the bed.

Bitter, dry, or harsh

Move one step coarser. If the brew also took much longer than usual, the filter may have clogged from fines.

Muddy and slow

Go coarser and pour more gently. If the bed looks silty, like wet cocoa powder, your grinder may be making too many fines for that brewer and filter combo.

Good flavor, but inconsistent

Keep the grind where it is and tighten up the rest: same dose, same water amount, same pour pattern. Inconsistent cups often come from a wandering recipe, not a bad grind setting.

How brewer shape and pouring change the grind

Brewer shape changes how fast water moves, so your grind may need a small shift between a cone, flat-bottom brewer, and thick-filter brewer. Cone and flat-bottom geometry changes flow; if you are shopping, read our guide to choosing a pour-over coffee maker.

As a loose starting point, V60-style cone brewers often like medium-fine, flat-bottom brewers can sit around medium-fine to medium, and Chemex-style thick filters often need slightly coarser grounds. Treat those as starting lanes, not commandments carved into a café wall.

Your pour matters too. A hard pour can disturb the bed and change drawdown, while a steadier stream is easier to repeat. If your kettle splashes like a garden hose, consider a gooseneck kettle for more controlled pours.
