Grind your Brazilian coffee for AeroPress at a medium-fine setting, roughly the texture of table salt, then adjust from there. A medium setting also works well for faster recipes and darker roasts. Because Brazilian beans are low in acidity and rich with chocolate and nutty notes, they extract quickly, so the grind you choose matters more than most brewers expect.
A burr grinder with stepped settings makes dialing in much easier than guessing on a blade grinder.
The Quick Answer: Medium-Fine to Medium
Most AeroPress recipes call for a medium-fine grind, and that is the right starting point for a typical medium-roast Brazilian coffee. If your cup tastes sour or thin, grind finer. If it tastes bitter or ashy, or the plunger fights you, grind coarser.
World AeroPress Championship recipes that use natural-process South American coffees tend to pair a medium to medium-fine grind with steep times between 1:30 and 2:00. James Hoffmann, in his widely followed AeroPress guidance, describes medium-fine as the balance point between surface area and flow resistance for immersion brewing.
The exact number on your grinder depends on your beans, your recipe, and your taste. Start in the middle of the range and adjust one step at a time.
Use This Grind Chart for Your Roast Level
Use the table below to pick a starting grind based on how dark your Brazilian coffee is roasted. Treat these as starting points, not final answers, because extraction also depends on water temperature and steep time.
| Roast Level | Starting Grind | Approx. Particle Size | Texture Reference |
| Light roast (e.g., high-grown Cerrado) | Medium-fine | 450 to 600 microns | Table salt |
| Medium roast (classic chocolate and nut) | Medium-fine to medium | 600 to 700 microns | Coarse salt to kosher salt |
| Dark roast (traditional espresso profiles) | Medium to medium-coarse | 700 to 850 microns | Sand to coarse kosher salt |
Light roasts are denser and harder to extract, so a finer grind helps pull out their sweetness and delicate fruit notes. Dark roasts are more porous and extract faster, so a coarser grind keeps the ashiness and harsh bitterness out of the cup.
Grinder Settings You Can Actually Use
Knowing “medium-fine” is one thing, but finding it on your grinder is another. These settings are practical starting points for popular grinders, gathered from common brewing guidance, and you should still confirm by taste.
- Baratza Encore: setting 12 to 15. The Baratza Encore ESP uses roughly 18 to 22 for this range.
- Comandante C40: 18 to 22 clicks on the standard axle.
- Timemore C2 or C3: 14 to 17 clicks from zero.
- Fellow Ode Gen 2: setting 3.0 to 4.2.
- 1Zpresso JX: about 2.0 to 2.4 rotations.
If your grinder jumps in big steps, split the difference by timing your press and adjusting water temperature instead.
A Complete Recipe to Dial In Your Grind
A grind setting only means something in the context of a recipe. Here is a solid baseline for Brazilian coffee in the AeroPress, informed by championship-level recipes:
- Dose: 15 grams of coffee, ground medium-fine.
- Water: 220 grams at 88 to 92°C (190 to 198°F). Lower temperatures protect the chocolate and caramel notes typical of Brazilian beans.
- Pour: Add the grounds, start a timer, and pour all the water within about 15 seconds.
- Stir: Gently stir 3 to 4 times to wet everything evenly.
- Steep: Insert the plunger slightly to create a seal and steep until 1:30.
- Press: Swirl gently, then press steadily for about 30 seconds, stopping when you hear a hiss.
A digital scale that reads in grams removes guesswork from both the dose and the water. A variable-temperature kettle makes the 88 to 92°C window easy to hit without a thermometer.
Troubleshooting by Taste and Feel
Your taste buds are the best diagnostic tool you have. Barista Hustle’s extraction guidance frames bitterness and dryness as signs of over-extraction, and sourness or thinness as signs of under-extraction.
If your cup tastes sour, watery, or thin, your grind is likely too coarse. Move a step or two finer and steep a little longer.
If it tastes bitter, dry, or ashy, your grind may be too fine or your water too hot. Go a couple of clicks coarser, and consider dropping your water temperature toward the lower end of the range.
If pressing is physically difficult, your grind probably has too many fines or is too fine overall. Coarsen it immediately to avoid straining the seal or blowing out the puck.
One detail worth remembering: these taste problems are not always caused by the grind alone. Water temperature and steep time interact with grind size, so when you change one, keep the others fixed so you know what actually fixed the cup.
Why Brazilian Beans Behave Differently
Most Brazilian coffee grows at lower altitudes than other origins, often with natural or pulped-natural processing. That combination produces beans that are less dense, less acidic, and more soluble than high-grown African or Central American coffees.
Lower density means the beans fracture differently in the grinder, producing more variability between grinders. It also means the soluble compounds that create sweetness and body dissolve quickly, which is why a slightly coarser grind often flatters Brazilian coffee where it would under-extract a denser Ethiopian bean.
If you take the same bag of Brazilian naturals into other brew methods, the same principles apply at different settings. The ideal approach for grinding Brazilian coffee for drip coffee runs a bit coarser, and the right grind for Brazilian espresso runs much finer. For something even gentler, coarse cold brew grinding with Brazilian beans leans toward the coarse end of the spectrum.
Conclusion
Grind Brazilian coffee for AeroPress at medium-fine, roughly 600 microns or the texture of table salt, and go coarser for dark roasts or finer for light roasts. Start with 15 grams of coffee and 220 grams of water at 88 to 92°C, then adjust one variable at a time based on taste. One small step in the right direction beats a big jump you cannot trace back.
