Coffee Grind Size Chart: The Right Grind for Every Brewer
Share
Match the grind to how long water touches the coffee: fine for a 30 second espresso shot, medium for drip and pour over, coarse for a four minute French press, and extra coarse for cold brew that steeps half a day. Finer grounds give up their flavor faster, so the shorter the brew, the finer you grind.
That is why the same beans can taste sour in one brewer and bitter in another. Start with the chart, then use the recipe card for your brewer and adjust by taste.

The coffee grind size chart
Particle sizes are measured in microns, or thousandths of a millimeter. The ranges are approximate, because every grinder labels its settings differently and real grounds always contain a spread of sizes. The texture column is the most useful guide.
| Brew method | Grind | What it feels like | Microns (approx.) |
|---|---|---|---|
| Turkish coffee | Extra fine | Flour or powdered sugar | under 220 |
| Espresso | Fine | Fine sand that clumps slightly when pinched | 200 to 400 |
| Moka pot | Fine to medium fine | Gritty between your fingers, but not powdery | 350 to 650 |
| AeroPress | Medium fine | Table salt | 350 to 800 |
| Pour over cone (V60 style) | Medium fine | Table salt | 400 to 800 |
| Auto drip machine | Medium | Regular sand | 600 to 900 |
| Chemex | Medium coarse | Rough sand or kosher salt | 700 to 1,000 |
| French press | Coarse | Coarse sea salt or breadcrumbs | 900 to 1,200 |
| Cold brew | Extra coarse | Cracked peppercorns | 1,000 to 1,400 |
Recipe cards for six brewers
Each card gives a reliable starting point. Keep the ratio, time and temperature steady while you dial in, so the grind is the only thing that changes. Temperatures are for water just off the boil unless noted.
Espresso
- GrindFine
- Ratio1:2, such as 18 g in, 36 g out
- Time25 to 30 seconds
- Water195 to 205°F (90 to 96°C)
The least forgiving brew on the chart. Water is forced through under high pressure, so one small step on the grinder changes the shot noticeably.
AeroPress
- GrindMedium fine
- RatioAbout 1:15 to 1:17
- Time1 to 2 minutes
- Water185 to 205°F (85 to 96°C)
The most flexible brewer here. Short brews like medium fine; longer steeps can move closer to medium.
Pour over
- GrindMedium fine
- Ratio1:16, such as 20 g to 320 g
- Time2 to 3 minutes after the bloom
- Water195 to 205°F (90 to 96°C)
Cone drippers like the V60 reward a table salt texture. A Chemex, with its thick filter, needs medium coarse so the brew does not stall.
Drip machine
- GrindMedium to medium coarse
- Ratio1:15
- Time4 to 6 minutes
- WaterSet by the machine
Most machines brew well at medium. Flat bottom baskets often taste better a little coarser, which is why our product pages suggest medium coarse.
French press
- GrindCoarse
- Ratio1:15 balanced, 1:12 bold
- Time4 minutes
- Water195 to 205°F (90 to 96°C)
A coarse grind keeps the cup clean and lets the plunger glide. Pour off as soon as you press so it does not keep extracting.
Cold brew
- GrindExtra coarse
- Ratio1:4 for a concentrate
- Time12 to 24 hours
- WaterCold or room temperature
Long, gentle steeping needs the coarsest grind on the chart. Anything finer turns murky and bitter. Dilute to taste before serving.
The moka pot sits between espresso and AeroPress on the chart. It runs on gentle steam pressure and clogs if the grind is too fine, which is why Bialetti, the company behind the classic moka pot, suggests a grind that feels gritty rather than powdery.
Why grind size changes the taste
Grinding multiplies the surface area that water can reach, so finer grounds dissolve faster. Brewers call this extraction, and flavors do not all extract at the same speed. Bright acids and fruity notes come out first, then sweetness, then the heavier, more bitter compounds. Pull out too little and the cup is sour, thin and hollow. Pull out too much and it turns bitter, dry and harsh.
Grind also works with time and flow. Immersion brewers such as the French press and cold brew soak the grounds for a long time, so they need a coarse grind. Percolation brewers such as pour over, drip and espresso push water through a bed of coffee, where finer grounds pack tighter and slow the water down. A pour over that drains too fast usually needs a finer setting; an espresso shot that barely drips needs a coarser one.
No grinder makes identical particles. Every batch holds some powdery fines, which add bitterness and sludge, and some larger boulders, which add sourness. A good burr grinder keeps that spread narrow. A blade grinder chops unevenly, so the same cup can taste bitter and sour at once.
How to tell if your grind is off
Taste is the quickest diagnostic. Find what you notice in the cup, then make the matching change, one small step at a time.
Sour, sharp or hollow
Grind a step finer. The coffee is underextracted, so the sweetness never arrived.
Bitter, dry or harsh
Grind a step coarser. The brew pulled out too much of the heavy, late compounds.
Sour and bitter at once
The grind is uneven. A burr grinder, or coffee ground to order, will fix it faster than any setting.
Pour over drains too fast
Grind finer so the bed slows the water toward the 2 to 3 minute mark.
Espresso barely drips
Grind coarser so the shot runs closer to 25 to 30 seconds.
French press is muddy or hard to plunge
Grind coarser, and pour off as soon as you press.
Roast matters too. Darker roasts dissolve more easily, so many brewers grind them slightly coarser, while denser light roasts often taste best a touch finer. Our light vs medium vs dark roast guide explains why.
Whole bean or ground to order
Grinding releases aroma quickly, so whole beans ground just before brewing give you the most flavor and full control. Without a grinder, coffee ground for your specific brewer is the next best thing.
Every Minero coffee comes as whole bean or ground to order for cold brew, French press, Chemex, auto drip, pour over or espresso. Double check that the grind matches your brewer, since coffee ground for the wrong method cannot be replaced. Three coffees that show what the right grind can do:
Dark roast, pulped natural Yellow Catuai from Carmo de Minas. Cocoa, caramel, hazelnut and a clean finish.
Try it: Coarse for French press, medium coarse for drip
Dark roast, natural processed Red Catuai from Cabo Verde. Honey, vanilla, citrus and a creamy body.
Try it: Coarse for French press
Medium roast Yellow Catucai from Campestre, with honey, hazelnut and cocoa tasting notes.
Try it: Medium fine for pour over

Two quick questions
Can I use espresso grind coffee in a drip machine or French press?
It is not ideal. Espresso grind is too fine for both, so a drip machine may overflow or taste bitter, and a French press will be muddy and hard to plunge.
Is a burr grinder really better than a blade grinder?
Yes. Burrs produce far more even grounds, which means cleaner, sweeter coffee with less bitterness and sediment. A blade grinder works in a pinch, but results vary from cup to cup.
