What this pour over grind size guide covers
A starting grind chart for the V60, Kalita Wave, and Chemex, starting settings on common grinders, why grind changes both flow and extraction, why each brewer needs a different grind, how dose, roast, filters, and grinder quality shift the setting, a three-brew calibration method, reading taste and drawdown together, fines and agitation, and when grind is not the real problem.
Editorial analysis
A chart should narrow the search, not replace your taste
Published grind settings are most useful as a shared language for texture. Once you start brewing, the right pour over grind size is whichever setting gives a balanced cup with your grinder, coffee, dose, filter, and dripper, and that rarely matches someone else’s number exactly.
Start from a brewer-specific texture, hold the rest of the recipe steady, and move the grinder in small steps based on taste and drawdown. Small, controlled changes teach you far more than chasing an exact click count.
The 30-Second Answer
Start medium-fine, like fine sugar, for a V60; medium, like table salt, for a Kalita Wave; and medium-coarse, like coarse sand, for a Chemex.
If the coffee tastes sour and drains fast, grind finer. If it tastes bitter or drying and drains slowly, grind coarser. Change one small step at a time and keep the rest of the recipe fixed.

Pour Over Grind Size Chart
Grind charts are useful only when they are treated as starting points. Medium is not a universal particle size, and two grinders can produce noticeably different results at settings with the same label. Brewer shape, paper thickness, dose, coffee density, pouring pattern, and the amount of fine particles your grinder produces all change how fast the water drains. Use the chart to get close, hold the rest of the recipe steady, and let the cup tell you when to stop adjusting.
| Brewer | Starting grind | Texture reference | Typical drawdown |
|---|---|---|---|
| Hario V60 | Medium-fine | Fine granulated sugar | Often about 2:45 to 3:30 for one cup |
| Kalita Wave | Medium | Table salt or slightly finer | Often about 2:45 to 3:30 |
| Chemex | Medium-coarse | Coarse sand or fine sea salt | Often about 3:30 to 4:30 for larger batches |
Those times are context, not pass or fail targets. A coffee that tastes balanced outside the range does not need forcing back toward a number, and a brew that lands inside the range but tastes sour or drying still needs adjustment. Getting the pour over grind size right is ultimately about the cup.
Starting Settings on Common Grinders
Grinder numbers only mean something on the grinder they belong to, but approximate starting points save time on the first brew. The settings below are typical places to begin for a single-cup V60. Go a few steps coarser for a Kalita Wave and noticeably coarser for a Chemex, then adjust by taste. Calibration varies between units, so expect your own best setting to differ by a step or two.
| Grinder | V60 starting point | Note |
|---|---|---|
| Baratza Encore / Encore ESP | Around 14 to 18 on the Encore; mid filter range on the ESP | Move one or two numbers at a time |
| Fellow Ode | Around 3 to 5 | Designed for filter coffee; small steps matter |
| KINGrinder K6 | Roughly 80 to 100 clicks from zero | Ten clicks is a noticeable change |
| Timemore Chestnut C2 | Roughly 15 to 18 clicks | Coarser for Chemex, around 20 to 24 |
| 1Zpresso JX | Roughly 2.0 to 2.5 rotations | Fine steps make dial-in precise |
If your grinder is not listed, find its pour over range in the maker’s instructions and start in the middle, then use the three-brew method below. The goal is not to match a number but to find the setting where your coffee tastes sweet and balanced with your dripper and filter.
Why Grind Size Changes Both Flow and Extraction
Smaller particles expose more surface area and pack more tightly, so water moves through the bed more slowly and dissolves more material. Coarser particles leave larger gaps, so water flows faster and usually extracts less for the same dose, ratio, and pour. That double effect, on both contact time and surface area, is why grind is the first variable to adjust when a brew is consistently too fast or too slow.
The relationship is not perfectly linear. Very fine particles, called fines, can migrate down to the filter and clog it, creating extra resistance. A grinder that produces a lot of powder can make a nominally medium setting drain much slower than a cleaner grinder at a similar-looking texture. That is also why grind charts transfer better between high-quality grinders than between a premium grinder and an entry-level one.
Why the V60, Kalita, and Chemex Need Different Grinds
The V60 has a single large drain hole and relatively thin paper, so most of its flow control comes from the grind and the pour. A medium-fine starting point gives the bed enough resistance to stop water racing through, while leaving room to go coarser if the brew stalls. Our Hario V60 recipe pairs this grind with a full dose, bloom, and pour schedule.
The Kalita Wave has a flat bed and three small drain holes, which build more resistance into the brewer itself. A slightly coarser grind than a typical V60 recipe can produce a similar total contact time, and the flat bed makes the Kalita less sensitive to small differences in pouring technique, which is why many beginners find it easier to repeat.
The Chemex changes the system most because its bonded paper is much thicker. The filter holds back more oils and fines and adds a lot of resistance, so Chemex recipes usually start coarser, especially for larger batches. Grinding a Chemex as fine as a V60 is one of the most common reasons for stalled, bitter brews.
How Dose and Batch Size Shift the Grind
A setting that works well for a 15-gram single cup may behave quite differently when you double the dose. A deeper coffee bed adds resistance, so larger batches usually need a slightly coarser grind to keep the drawdown from slowing too much. Smaller doses make a shallow bed that drains faster and may need a slightly finer grind to extract fully. This effect is strongest in brewers with thick paper or restricted drainage.
Treat grind as part of a complete recipe rather than a fixed number. If you scale from 20 grams to 30 or 40 grams in the same brewer, start near your usual setting, watch the drawdown, and be ready to go coarser if the bigger bed stalls or the cup turns drying. Changing the amount of water alone is different: more water mostly affects strength, so judge strength separately before changing the grind.
Brewing for two in a single-cup dripper is a common example. Moving from 15 grams to 30 grams in a V60 02 roughly doubles the bed depth, so the same setting that drained in three minutes may now take four or more and taste heavy. Going two or three steps coarser usually brings the time back and keeps the cup clean. If you regularly brew larger batches, a bigger dripper or a Chemex spreads the bed out and makes the pour over grind size easier to manage than piling more coffee into a small cone.
Roast Level and Grind Direction
Roast level does not dictate one exact pour over grind size, but it does suggest a starting direction. Lighter roasts are denser and less soluble, so they often respond well to a slightly finer grind, hotter water, or both. Sharp acidity, hollow sweetness, or a very fast drawdown suggests a light roast is under-extracting. Medium roasts work well at the brewer baseline and are the easiest coffees to learn on.
Darker roasts extract readily and turn harsh when the grind is too fine or the water too hot, so start a little coarser and slightly cooler. Drying bitterness, roasty harshness, or sluggish flow suggests reducing extraction. Bean density, processing, age, and your grinder can all move the ideal setting, so use roast level as a first nudge rather than a fixed rule. Our pour over water temperature guide covers the temperature side.
A Three-Brew Calibration Method
The fastest way to find a good setting is a simple three-brew test. Keep the dose, water amount, temperature, filter, and pouring pattern exactly the same, and change only the grinder. That gives a clean comparison instead of a moving target, and it usually shows within three cups which side of the useful range you are on.
For the first brew, use the chart’s starting texture, then note the total drawdown time and a short taste note. If the cup is clearly sour or thin, move one or two small steps finer for the second brew; if it is clearly bitter or drying, move one or two steps coarser. For the third brew, make a smaller move in whichever direction improved the cup. Once you are close, smaller changes in temperature, ratio, or pouring can refine the flavor without losing your baseline. Writing down the setting and result for each coffee makes the next bag much faster to dial in.
Reading Taste and Drawdown Together
Taste tells you which direction to move, and drawdown tells you why. Sharp, sour, hollow, or thin coffee usually means extraction is too low or the flow too fast, so grind one small step finer. Drying, harsh, bitter, or heavy coffee usually means extraction is too high or the drawdown too slow, so grind one step coarser before changing anything else. If the cup is balanced but simply too weak or too strong, the ratio is the problem rather than the grind.
Combining the two signals prevents wrong turns. A sour cup with a very fast drawdown points clearly to a finer grind. A sour cup with a very slow drawdown is different and may mean channeling, poor saturation, or water that is too cool, which grind alone will not fix. A very slow brew that still tastes sweet and balanced needs no correction just to hit a time target. And a normal-looking time with both sour and drying notes usually points to uneven particle size or channeling rather than the average grind setting.
Dial-In Differences by Brewer
The same flavor problem can need a different-sized correction depending on the brewer. The V60 reacts quickly to grind changes because its drain adds little restriction; if it runs fast and sour, a small step finer is usually enough, and if it runs slow and drying, go coarser and pour more gently. Check that the bed drains evenly and that your pour rate is consistent from brew to brew.
The Kalita Wave already has built-in resistance, so small grind moves go a long way. Move slightly finer for sour cups and coarser for drying ones before adding more agitation, and check that the filter sits flat with the bottom holes unobstructed. With the Chemex, move finer cautiously, because the thick paper and larger dose make over-fine grinds especially likely to stall. If a Chemex drains slowly, also check that the filter’s thick side faces the spout so the air channel stays open.
When to Change Grind, and When Not To
Grind is usually the first adjustment because it changes both flow and extraction, but using it for every problem creates confusion. If the brew is clearly too fast or too slow, change the grind. If the cup is balanced but too weak or too strong, change the ratio instead. If a light roast tastes dull even with the grind close, try a slightly higher water temperature, which raises extraction without changing flow.
If drawdown varies widely between identical brews, the issue is usually pouring consistency or agitation rather than the grinder. And if the coffee tastes flat at every setting, look at freshness and water, since grind cannot restore stale aromatics. A consistent burr grinder such as the Baratza Encore ESP or a hand grinder like the KINGrinder K6 makes every one of these diagnoses easier, because each setting behaves predictably.
Grinder Quality Changes What Correct Looks Like
A good burr grinder narrows the spread of particle sizes enough that one setting gives a predictable flow. Entry-level grinders can still make excellent pour over, but their best settings may sit further from published charts because they produce more fines and more large fragments at the same time. Blade grinders produce such an uneven mix that a consistent pour over grind size is very hard to achieve.
That does not mean every brewer needs a premium grinder; it means a chart becomes more useful as the grinder becomes more consistent. If two brews at the same setting behave very differently, check the dose, bean age, filter seating, and pouring technique before assuming the chart is wrong. Cleaning the burrs and clearing old grounds trapped in the grinder also helps, since stale retained coffee mixes into each new dose. Our best burr grinders for pour over guide compares options.
Paper Filters Can Shift the Ideal Grind
Paper is part of the brewing system. A thick or slow filter can make a recipe stall even when the grind has not changed, while a faster paper can shorten drawdown enough that the same grind tastes under-extracted. Filter brand, manufacturing batch, and how thoroughly the paper is rinsed all play a part. Thin cone papers such as Hario V60 filters flow relatively freely, Kalita Wave filters have their own steady flow, and Chemex bonded filters add considerable resistance.
For that reason, dial in the grind only after choosing the filter you will use regularly. If you switch from standard V60 paper to a slower specialty paper, or from cone paper to Chemex filters, expect to revisit the grind. Always rinse paper filters with hot water before brewing, which removes papery flavors and helps the filter seat properly against the dripper. Our pour over filter comparison goes deeper.
Fines, Agitation, and a Clean Drawdown
Every grinder produces some fines, the dust-like particles much smaller than the target size. In pour over they matter because they move. Heavy pouring, stirring, or swirling pushes fines down toward the filter, where they can clog the paper and slow the drawdown. That is why the same pour over grind size can drain quickly with a gentle pour and stall with an aggressive one, and why changing your pouring style can look like a grind problem.
Gentle, consistent agitation keeps the bed even without driving fines into the paper. Pour in a steady spiral with the spout close to the coffee, use a light swirl after the bloom or the final pour rather than vigorous stirring, and avoid pouring directly onto the filter walls. Some enthusiasts sift out fines with a fine mesh sieve for a cleaner, brighter cup, but for most people a decent burr grinder and a calm pour achieve most of the same benefit with far less effort.
When Grind Size Is Not the Real Problem
If repeated grind changes move the drawdown but do not improve the flavor, another variable is probably in control. Inconsistent pouring can cause channeling, a poorly seated filter can restrict or redirect flow, and stale coffee tastes flat at any particle size. Water that is very hard, very soft, or heavily chlorinated can also make a technically correct brew taste muted or harsh.
Work through these in order. If drawdown swings from brew to brew, check the pour rate, agitation, dose accuracy, grinder retention, and filter seating. If the flavor stays flat at every setting, try fresher coffee and filtered water. If the brew stalls even at a fairly coarse setting, look for excess fines, aggressive stirring, slow paper, or a filter clinging to the dripper wall. If a fast brew still tastes bitter, check the water temperature, roast level, and ratio. Our pour over troubleshooting guide covers each problem in detail.

Editorial bottom line: The right pour over grind size starts medium-fine for a V60, medium for a Kalita Wave, and medium-coarse for a Chemex. From there, hold the recipe steady and move the grinder in small steps: finer for sour, fast brews and coarser for bitter, slow ones. Adjust for dose, roast, and filter, and use a consistent burr grinder so each setting behaves predictably.
Frequently Asked Questions
What grind size should I use for pour over?
Start medium-fine for a V60, medium for a Kalita Wave, and medium-coarse for a Chemex. Then adjust by taste and drawdown time. Charts are starting points; your cup is the final judge.
Why does my pour over taste sour?
Sour coffee is usually under-extracted, often because the grind is too coarse and water drains too quickly. Grind one small step finer and keep everything else the same.
Why is my pour over bitter?
Bitterness usually comes from over-extraction caused by a grind that is too fine, heavy agitation, or a very slow drawdown. Grind slightly coarser and pour more gently.
Does the filter affect grind size?
Yes. Filter thickness and shape change flow resistance, so switching from thin V60 paper to thick Chemex paper, or between brands, can change drawdown at the same grind setting.
Should I grind coarser for a bigger batch?
Usually, yes. A larger dose makes a deeper coffee bed that slows flow, so a slightly coarser grind keeps the brew from stalling or turning bitter.
What if grind changes do not fix my coffee?
Check pouring consistency, filter seating, coffee freshness, and water quality. Uneven grinders, dirty burrs, and stale beans can all limit what any grind setting can achieve.
