Best Grind Size for Pour-Over Coffee
The best grind size for pour-over coffee is medium-fine — roughly the texture of fine sea salt or kosher salt, finer than table sugar but coarser than espresso. That setting works for the most common pour-over drippers (V60, Kalita Wave, Origami, Beehouse) brewing 15–20g of coffee in 2:30 to 3:30. Adjust finer if the cup tastes sour or weak, coarser if it tastes bitter or drains too slowly.
This guide covers exactly what medium-fine looks like, how to adjust grind for different drippers and roast levels, and what to do when your pour-over is draining at the wrong speed.
The Quick Answer by Dripper
Different pour-over cones have different drainage geometries, so the ideal grind shifts slightly between them.
Hario V60 — Medium-fine. Single large hole at the bottom means flow is controlled almost entirely by your pour and grind. Target brew time: 2:30–3:30 for a single cup.
Kalita Wave — Medium to medium-fine, a touch coarser than V60. The flat-bottomed bed and three small holes regulate flow naturally, so you don't need as fine a grind to slow drainage.
Origami Dripper — Medium-fine, similar to V60. Pleated walls drain quickly; the grind size does most of the regulation.
Beehouse / Melitta-style — Medium, coarser than V60. Two small holes restrict flow on their own.
Chemex — Medium-coarse, distinctly coarser than the rest. Covered in detail in our Chemex grind size guide.
What Medium-Fine Actually Looks Like
Without a particle analyzer, the cleanest reference is kitchen ingredients. Medium-fine sits between fine sea salt and granulated sugar — distinct grains, loose and sandy in your fingers, no dust clumping or visible chunks.
If you're using a burr grinder with numbered clicks, find your manufacturer's pour-over recommendation as a starting point. Common reference points:
- Comandante C40 — clicks 18–24 (lighter roasts finer)
- Baratza Encore — settings 15–20
- 1Zpresso JX — clicks 65–80
- Fellow Ode Gen 2 — settings 4–6
These are starting points, not destinations. Your specific bean, roast date, and water temperature all push the dial. The cup is the final arbiter.
How to Dial In Your Grind
The process is the same regardless of dripper:
1. Start with a known reference. Pick your grinder's mid-range pour-over setting and brew at 1:16 ratio (15g coffee to 240g water). 2. Time the brew. From first drop of water to last drop of coffee draining out — aim for 2:30 to 3:30 for a V60, slightly longer for a Kalita. 3. Taste. Sour, weak, hollow? Grind finer. Bitter, dry, harsh? Grind coarser. 4. Adjust one click at a time. Brew the same recipe again. Re-taste.
Most pour-overs are sitting one or two clicks off, not five. Small adjustments. Don't change ratio, temperature, and grind at the same time — you'll learn nothing.
How Roast Level Changes the Math
The standard grind chart assumes a medium roast. Adjust for what's in your bag.
Light roasts are dense and slow to extract. They benefit from a finer grind (one or two clicks tighter than your medium-roast setting) and hotter water (95–96°C / 203–205°F). Light Ethiopian washeds and Kenyan SLs especially reward going finer.
Medium roasts sit on your default setting. Most coffees brew well here without much adjustment.
Dark roasts are brittle, porous, and extract fast. Pull back one or two clicks coarser and drop water temperature to 90–92°C (194–198°F). Otherwise the cup turns ashy.
Naturals and anaerobics often have softer cell structures and extract faster than washed coffees. Treat them like a half-step coarser unless you specifically want a bigger, more intense cup.
The SCA's brewing extraction standards target 18–22% extraction yield, and grind size is the lever that gets you there.
Diagnosing Pour-Over Problems by Drawdown Time
Pour-over has the great advantage of giving you a visible diagnostic — drawdown time. If your brew is finishing in the wrong window, grind is almost always the cause.
Drawdown under 2:00: grind too coarse, or pour too aggressive. Coarse grind lets water rip through the bed without extracting fully. Tighten the grinder.
Drawdown 2:00–2:30: likely under-extracting unless you're using a high ratio (1:17+). Tighten the grinder one click and brew again.
Drawdown 2:30–3:30: target zone for most V60 recipes. Taste the cup.
Drawdown 3:30–4:30: approaching over-extraction territory. Acceptable for some light roast recipes (James Hoffmann's 1:16.7 method aims here on purpose) but most beans will taste better closer to 3:00.
Drawdown over 4:30: grind too fine, or fines from your grinder are clogging the filter. Coarsen up one or two clicks. If it still won't drain, see our piece on grinder particle distribution — fines are likely the culprit.
Common Mistakes
- Grinding too coarse and brewing too long. The natural reaction to a fast drawdown is to pour slower, but if the grind is wrong the extraction will still be uneven. Fix grind first.
- Forcing one grind across every brew. Different beans need different settings. Always re-dial when you open a new bag.
- Trusting volume measurements. "Two scoops" is meaningless when grinds vary. Always weigh.
- Blade grinder on a V60. Pour-over is the most grind-sensitive method short of espresso. A blade grinder will sabotage every cup regardless of recipe. Even an entry-level hand burr grinder beats it by miles.

Frequently Asked Questions
What grind size for V60?
Medium-fine — like fine sea salt or kosher salt. A 15g dose of medium-roast coffee in a V60 02 should draw down in 2:30 to 3:30 with a 1:16 ratio. Light roasts go one or two clicks finer; dark roasts go one or two clicks coarser.
Is pour-over grind the same as drip coffee grind?
Close but not identical. Drip coffee machines control flow rate for you and generally want a medium grind, slightly coarser than V60. Pour-over leaves flow control to the brewer, so the grind takes on more of the regulation work.
My pour-over is draining too slowly. What's wrong?
Either grind too fine or excessive fines from your grinder clogging the filter. Coarsen one or two clicks first. If the problem persists, your grinder may be producing too many fines — a common issue with blade grinders and worn-out burrs.
Should I grind finer for light roast pour-over?
Yes. Light roasts are denser and slower to extract, so they benefit from a finer grind and hotter water (95–96°C). Move one or two clicks finer than your default and bump water temperature up.
Can I use a French press grind for pour-over?
No. French press grind (coarse, like sea salt flakes) is far too coarse for pour-over — water runs through too fast and the cup will be thin and sour. Pour-over wants roughly half the particle size.
What Gets Brewed Matters As Much As How
A Pinkies Out co-ferment from Lamppost — a Golden Bean World Series winner — opens completely differently in a V60 than in a French press. That's the kind of coffee Podium Coffee Club was built to ship: beans from roasters who've placed at the major blind-judged competitions, sent within 24 hours of roasting, no marketing-flavoured filler in the line-up.
Podium Gold starts at $24.50/month for a 300g bag — the cleanest entry point. Podium Platinum is $29.50/month for the more experimental picks. Both whole bean, both shipped between the 5th and 10th of each month. If you're shopping the category, our guide to the best coffee subscriptions maps the field.
