Coffee grind size chart: the right grind for every brew method
Updated:
Grind size decides how quickly water extracts flavour from coffee. This coffee grind size chart shows the right setting for every brew method, plus simple rules for dialling it in.
In short
- Finer
- longer, stronger extraction
- Coarser
- shorter, milder extraction
- Sour or thin
- grind finer
- Bitter or dry
- grind coarser
- Test recipe
- keep dose, water and temperature fixed
- Freshness
- grind just before brewing
Why grind size matters
When you brew, water dissolves acids, sugars and bitter compounds from the grounds – and not all at once. Fruity acids dissolve first, then sweetness and body, and bitter compounds last. The finer you grind, the larger the surface area and the faster and stronger the extraction. Fine grounds also slow down the flow of water. That is why every brew method needs a grind size that matches its contact time: a short contact time like espresso calls for a fine grind, a long one like the French press calls for a coarse grind.
Grind size chart for every brew method
| Brew method | Grind | Looks like | Brew time |
|---|---|---|---|
| Turkish coffee | extra fine | icing sugar | 2–3 min |
| Espresso | fine | fine sand | 25–30 s |
| Moka pot | fine to medium-fine | slightly coarser than espresso | 4–5 min |
| AeroPress | fine to medium | depends on the recipe | 1–3 min |
| V60 & pour-over | medium-fine | table salt | 2:30–3:30 min |
| Drip coffee machine | medium | coarse sand | 4–6 min |
| Chemex | medium-coarse | slightly coarser than table salt | 4–5 min |
| French press | coarse | coarse sea salt | 4 min |
| Cold brew | extra coarse | cracked pepper | 12–24 h |
How to dial in your grind
- Start with the guide value. Set your grinder to the range in the chart and brew with a fixed recipe: same dose, same amount of water, same temperature.
- Check the brew time. If it is well outside the guide value, the grind is off. Too fast? Grind finer. Too slow? Grind coarser.
- Taste. Sour, thin or salty means under-extracted – grind finer. Bitter, dry or hollow means over-extracted – grind coarser.
- Adjust in small steps. Change only one setting per attempt, and only by one or two steps. That way you can tell what each change does.
- Take notes. Write down the setting you like. With the next coffee – or a new bag – you'll save yourself a lot of trial and error.
Burr or blade grinder?
Good coffee needs a grinder that produces evenly sized particles. Conical and flat burr grinders crush the beans between two burrs and give a consistent result. Blade grinders chop the beans with a spinning blade instead, creating a mix of dust and large pieces that over- and under-extract at the same time. If you don't have a good grinder, coffee ground by the roaster is the better choice – on our product pages you can choose the grind for espresso, filter or French press.
When to adjust your grind again
The perfect grind isn't a fixed value. Every new coffee behaves differently: density, roast level and freshness all affect how quickly water flows through. Beans also change as they age – older beans often need a slightly finer grind. With espresso, even humidity and room temperature play a part. So briefly check brew time and taste with every new bag and adjust if needed.
Troubleshooting
My coffee tastes sour
Under-extraction: the water had too little time or too little surface area. Grind finer.
My coffee tastes bitter and dry
Over-extraction: grind coarser or shorten the brew time.
My coffee tastes sour and bitter at the same time
A typical sign of uneven grinding. Check your grinder – blade grinders and worn burrs create lots of dust alongside large pieces.
Nothing changes after I adjust the grinder
Many grinders retain some grounds. After adjusting, grind a few grams through before you judge the next cup.
Frequently asked questions
What grind size is right for espresso?
Fine, roughly like fine sand. The goal is a shot of 25–30 seconds at a 1:2 ratio, for example 18 g of coffee to 36 g of espresso. Find out more in our espresso guide.
Can I compare grind settings between grinders?
No. Setting 10 on one grinder is not setting 10 on another. Go by brew time and taste rather than numbers.
What grind size for a bean-to-cup machine?
Start in the middle of the range and go finer until the coffee tastes strong but not bitter. Many machines should only be adjusted while the grinder is running – check your manufacturer's instructions and our bean-to-cup guide.
What grind size for cold brew?
Extra coarse, roughly like cracked pepper. Because the coffee steeps cold for 12 to 24 hours, a fine grind would make it bitter and cloudy.
How long does ground coffee stay fresh?
Much less time than whole beans: the first aromas fade within minutes. Store ground coffee airtight and use it within one to two weeks.
