single mug, a kitchen scale, and about three minutes from grinding to first sip. The AeroPress is the brewer you reach for when you want one good cup with almost no ceremony, at home or packed in a bag on the road.
It works by immersion plus a gentle push: the grounds steep in hot water, then you press the brew through a paper filter. The steep does most of the extraction, and the paper keeps the cup clean. That combination is what makes it fast, forgiving, and easy to repeat the same way every morning.
This guide gives you one solid recipe, the few numbers that matter, and the two ways to set the brewer up. Follow it once and you will have a baseline you can adjust to your beans.
What you need and the numbers that matter
An AeroPress with a cap, one paper filter, a kettle, a scale, a stir paddle or spoon, and a timer. Grind your coffee fresh if you can. The AeroPress is small and quick, so the main thing to get right is grind size and the press itself.
Grind size: medium-fine. That is finer than a V60 pour-over and noticeably coarser than espresso. If your grind is too coarse the cup comes out thin and sour. Too fine and the press becomes hard to push and the cup turns bitter.
A solid standard recipe is about 15 g of coffee to roughly 220 to 250 g of water, which lands near a 1:15 ratio. Heat the water to between 88 and 92 degrees Celsius, a touch below the boil. Lower temperatures tame bitterness, which helps with darker roasts in particular. The whole brew, from first pour to the end of the press, takes about 1.5 to 2 minutes.
Standard or inverted
There are two ways to set the brewer up. Standard means the cap with the filter sits at the bottom, on top of your mug, and the brew slowly drips through while it steeps. It is simple and the version most people start with.
Inverted means you assemble the chamber upside down, with the press end at the bottom, so no liquid drains out before you are ready. You brew, cap it, then flip the whole thing onto your mug to press. It costs a small amount of drip during the steep but gives you full control over steep time, which some brewers prefer.
Both make a similar cup. The recipe below uses the standard setup because it is the easier one to learn. Once it is familiar, try inverted and see whether you taste a difference.
The brew, step by step
Rinse the paper filter with hot water before you brew. This washes off any papery taste and warms the cap. Discard the rinse water from the mug.
- Rinse and assembleSeat a rinsed paper filter in the cap, screw the cap on, and stand the AeroPress on your mug. Add 15 g of medium-fine grounds and give it a gentle shake to level the bed.
- Pour to weightStart the timer and pour to 235 g, wetting all the grounds evenly. Pour with enough energy to saturate the bed, not so hard that grounds climb the chamber.00:20235 g90 °C
- StirStir a few times with the paddle to knock down any dry clumps and even out the slurry.00:10
- SteepInsert the plunger a short way to seal the chamber and stop dripping, then let it steep for about a minute.01:00
- PressPress down slowly and steadily over 20 to 30 seconds. Stop the moment you hear the hiss of air at the bottom. Do not force the last air through.00:25
Adjusting and a stronger variation
Taste before you change anything. Sour and thin usually means the cup is under-extracted: grind a little finer, or nudge the water hotter toward 92 degrees. Bitter and drying usually means over-extraction: grind coarser, drop the temperature toward 88 degrees, or ease off on the press.
For a stronger result, brew a concentrate. Keep the coffee weight up but cut the water down, for example 18 g of coffee to 120 g of water, press as usual, then dilute the concentrate with hot water in the cup until it tastes right to you. This gives you a fuller cup without grinding finer and stalling the press.
Change one thing at a time and write down what you did. The AeroPress is repeatable enough that a small, deliberate change shows up clearly in the next cup.
Common questions
- Inverted or standard AeroPress?
- Both make a similar cup, so start with standard because it is simpler: the cap sits on your mug and the brew steeps in place. Inverted assembles the chamber upside down so nothing drains before you flip and press, which gives you tighter control over steep time. Try inverted once standard feels routine and keep whichever you prefer.
- What grind for AeroPress?
- Medium-fine. That is finer than a V60 pour-over and coarser than espresso. Too coarse and the cup turns thin and sour. Too fine and the press gets hard to push and the cup turns bitter. If you are unsure, start at medium-fine and adjust by taste one notch at a time.
- Why is my AeroPress coffee bitter?
- The two usual causes are forcing the press and over-extraction. Press slowly over 20 to 30 seconds and stop the instant you hear the hiss of air, since pushing that last air through pulls harsh notes into the cup. If it is still bitter, grind a little coarser and lower the water toward 88 degrees Celsius, which is especially worth doing for darker roasts.
