What grind size should I use for pour over?
A drip coffee can go from bright and sweet to flat or bitter because of one small detail: the grind. If you have wondered what grind to use for pour over, the short answer is medium to medium-coarse. The real answer, the one that actually changes the cup, is that it depends on the dripper, the filter, the coffee, the roast, and even how you pour the water.
In pour over, there is no single perfect grind for all coffees. There is only the right grind for that recipe, that coffee, and that moment. For this reason, rather than memorizing a grinder setting, it is better to learn to read what is happening in the cup.
What grind to use for pour over based on the result you are looking for
Pour over highlights clarity, clean texture, and defined notes. To achieve this, the grind must allow for an even extraction. If it is too fine, the water takes too long to pass through and the cup can turn out bitter, drying, or heavy. If it is too coarse, the water passes too quickly and the coffee feels watery, acidic, or lacking sweetness.
As a starting point, think of a texture similar to table salt that is a little bit coarser. That reference works well for many conical-bottom and flat-bottom drippers. It is not a rigid rule, but it is a good beginning when you are calibrating.
The most useful thing is to understand the balance. A finer grind extracts more and increases body and intensity, but it also raises the risk of bitterness and the filter clogging. A coarser grind provides more cleanliness and can highlight pleasant acidity, although if you go too far, you lose sweetness and depth.
For V60 and conical drippers
In a V60, the flow is usually faster and sensitive to the pouring technique. Here, a medium grind usually works, sometimes leaning toward medium-fine if the coffee is denser or if you are looking for more intensity. If you grind too fine, the extraction time increases and the profile becomes harsh.
With coffees with floral, citrus, or fresh fruit notes, a medium grind helps to maintain definition and brightness. If the coffee has a light roast, you will probably need to grind a little finer to better develop the sweetness.
For Chemex
The Chemex usually requires a slightly coarser grind. Its filter is denser and retains more oils and solids, so a very fine grind can slow the flow too much. The ideal result is usually a clean, elegant cup with a lot of flavor separation.
If your beverage turns out thin when preparing with a Chemex, it does not always mean you need more coffee. Sometimes you just need to tighten the grind a bit to gain extraction without losing that characteristic cleanliness.
For Kalita Wave and flat-bottom drippers
In flat-bottom drippers, extraction tends to be more stable. Therefore, a medium grind usually produces very good results. These methods tend to be a bit more forgiving than a V60, but they still respond with clarity when you adjust well.
If you are looking for a sweeter and rounder cup, you can lean slightly toward a finer grind. If you notice bitterness at the end, open up the grind a little before changing the whole recipe.
How to know if your grind is too fine or too coarse
Your best guide is not the number on the grinder. It is the cup.
If the coffee tastes bitter, dry, heavy, or leaves an astringent sensation, it is possible that the grind is too fine. This can also happen if the total extraction time was very long or if you agitated the coffee bed too much.
If the cup tastes aggressively acidic, salty, hollow, or is very fleeting on the palate, the grind is likely too coarse. In that case, the water did not manage to extract the sugars and compounds that provide balance.
There is a visual sign that helps: observe the coffee bed at the end. If it is very muddy or compacted, you might be grinding too fine. If you see large particles and a very fast extraction, you are surely too coarse.
Time helps, but it is not the only rule
Many people use time as their main reference. It is useful, of course, but it is not advisable to follow it blindly. A pour over can finish in 2:45 or 3:30 and still be good, depending on the coffee, the grinder, and the recipe.
The important thing is to relate time and flavor. If the extraction was long but the cup is sweet and clean, there is no problem. If it fell within the “correct” range and tastes hollow, the problem was not the timer.
The type of coffee also changes what grind to use for pour over
Not all beans respond the same way. A higher-altitude coffee, which is denser and lightly roasted, usually requires a slightly more demanding extraction. This often means grinding slightly finer to better bring out its notes.
On the other hand, a coffee with a medium or more developed roast may benefit from a slightly coarser grind to avoid saturating the cup and hiding its natural sweetness behind bitterness.
The sensory profile also plays a role. If you have a coffee with notes of red fruits, citrus, or flowers, a well-calibrated grind helps those layers appear with clarity. If the profile leans more toward panela, chocolate, or ripe fruit, you can play with a slightly finer grind to gain body without losing clarity.
That is one of the beauties of pour over: it lets you listen better to the origin. In estate-grown coffees, well-crafted from the cherry to the roasting, the grind does not just affect intensity. It affects the way the flavors are told in the cup.
Grinder consistency matters more than it seems
You can have great coffee, a good recipe, and correct water, but if the grinder produces very uneven particles, extraction becomes complicated. Some particles end up over-extracted and others under-extracted. The result usually feels confusing: sharp acidity combined with bitterness, as if the cup were fighting itself.
That is why, when someone asks what grind to use for pour over, it is also worth asking what grinder they have. A burr grinder, manual or electric, provides much more consistency than a blade grinder. It is not a technical whim. It is a real difference in flavor.
If your grinder does not have much precision, adjust with patience and change only one variable at a time. Sometimes a small movement does more than you imagine.
A simple way to find your sweet spot
Start with a stable recipe. For example, a 1:16 ratio, water between 92 and 96 degrees Celsius, and a medium grind. Prepare the cup and taste it when it cools down a little. Hot coffee always hides information.
If it tastes very intense, bitter, or drying, open the grind one notch. If it tastes very light, sharp, or lacking sweetness, tighten it one notch. Repeat until you find a sweet, clean cup with a pleasant finish.
Make changes one by one. If you change the grind, dose, and temperature at the same time, you will not know what improved or ruined the brew.
What is best to adjust first
In pour over, the grind is usually the first lever. Before drastically changing the recipe, correct the grind. Afterward, you can refine the pouring, temperature, or ratio.
This simplifies the process and avoids frustration. Often, the coffee was not "bad." It was just asking for a different grind.
Common mistakes when choosing the grind
One of the most frequent mistakes is copying someone else's setting without considering the coffee or the grinder. The same number can mean different things on two different grinders. Even on the same grinder, the coffee changes its behavior depending on its origin, process, and freshness.
Another mistake is chasing only more strength in the cup and closing the grind too much. In pour over, more extraction does not always mean better flavor. If you cover up the clarity, you lose one of the most beautiful qualities of the method.
The opposite also happens: opening up the grind too much to "make it cleaner" and ending up with a hollow cup. Cleanliness without sweetness feels incomplete.
When the grind is right, the coffee speaks clearly
A good grind does not call attention to itself. It lets the notes, the balance, and the texture that the coffee already possesses come through. This is especially valuable when you prepare single-origin coffees with defined sensory profiles, because each adjustment can bring you closer to or further from what makes that cup special.
If you are looking for a simple rule, start with medium to medium-coarse. If you are looking for a truly good cup, listen to the flavor and adjust from there. Pour over rewards patience, and when you hit the exact spot, the coffee becomes clearer, sweeter, and much more memorable.
The next time you grind for your drip coffee, do not think only about size. Think about what you want to feel in the cup. That is where a better preparation begins, from the grind to the very last sip.
