How to Grind Coffee for Pour Over (2026)

Quick answer

Begin medium-fine, grind immediately before brewing, and change only one small grinder step at a time. Move finer for a fast, sour brew; move coarser for a slow, bitter brew. Blue Bottle’s pour-over brew guide uses a medium starting point, while KitchenAid’s guide calls medium to medium-fine, roughly sand-like—not an exact measurement.

What you’ll need

An adjustable burr grinder is the tool that makes dialing in repeatable; it produces more even grounds than a blade grinder and gives you a consistent place to make small changes. See our pour-over grinder picks if yours cannot hold a setting reliably. Counter Culture Coffee’s Guide to Pour-Over Coffee also recommends a quality burr grinder and grinding just before brewing.

• Whole beans — use the same coffee while you figure out the grind.
• Pour-over dripper and filter — rinse the filter and brew the same way each time.
• Scale and timer — these keep your recipe from drifting under your feet.
• Kettle — a steady, gentle pour makes the result easier to read.

How to grind coffee for pour over in five steps

Use a medium-fine starting point, then let taste and flow guide small changes. Grinder numbers are not portable: “20” on one model may look and brew nothing like “20” on another, so skip universal click charts.

Step 1: Measure your beans

Weigh the beans for your usual recipe before you grind. Pick one dose and water amount, then stick with them while you adjust the grinder; otherwise every cup becomes a guessing game.

Step 2: Set medium-fine as your starting point

Set the grinder around medium-fine: think between table salt and fine sand, with distinct grains rather than dusty flour. It is a useful first guess, not a finish line. Lighter coffees, different filters, and different drippers can all want a different spot.

Step 3: Grind immediately before brewing

Grind the dose, then get the grounds into the dripper without letting them sit around. Counter Culture Coffee recommends fresh grinding because coffee loses its fragrant, lively character after it is ground.

Step 4: Brew and notice what happened

Brew your normal recipe and pay attention to two things: the taste and whether water seems to race through or linger stubbornly on top. Extraction—how much flavor water pulls from the grounds—only matters here because it gives you a practical next move.

Step 5: Change one small grinder step

Keep the dose, water, filter, and pouring routine the same; use a coffee scale for repeatable pour-over recipes so you are not changing the recipe by accident. For a fast, sharp sour cup, go a little finer. For a slow, dry bitter cup, go a little coarser. Stumptown Coffee’s How to Perfect Your Pour Over Coffee offers the same sour/fast-to-finer and bitter/slow-to-coarser diagnostic as a starting point.

Common pour-over grinding mistakes

The biggest mistake is treating the grind dial like a recipe card. Your number is useful only because it helps you return to a good cup on your own grinder.

• Chasing somebody else’s click count — write down your own setting instead; burr size and the dial’s zero point differ by grinder.
• Changing three things at once — do not alter grind, dose, and pour speed together. You will not know what fixed the cup.
• Judging only by the grounds’ look — the sand-like cue is approximate. Taste and flow get the final vote.
• Blaming the grind for a wild pour — an aggressive stream can stir the coffee bed and slow the brew even when the grind is fine.

Troubleshoot your pour-over grind by symptom

Use the cup as your compass: fast and sour points finer; slow and bitter points coarser. Change one thing for the next brew, not halfway through the one in front of you.

The coffee is sour and water runs through fast

Move the grinder one small increment finer, then repeat the same recipe. If the flow still races, check for a channel—water finding one easy path through the bed—by making sure the grounds are level before you start pouring.

The coffee is bitter, dry, or drains slowly

Move one small increment coarser. Fines, the powdery little bits in uneven grounds, can clog a filter and stretch the brew; a burr grinder helps, but even a good grinder may need a coarser setting for some coffees.

The result changes when you use another dripper

Start over from medium-fine for the new brewer. Cone drippers, flat-bottom brewers, and larger drippers hold water differently, so do not assume a saved setting will travel. Browse our recommended pour-over coffee makers for those different shapes, and remember that a gooseneck kettle for controlled pouring can change flow rate too. A slow brew is not automatically a grind-only problem.
