How do you brew AeroPress coffee?
Quick answer
15 g coffee, 210 ml water (1:14), water 88 °C (190 °F), medium-fine grind. Keep the brewer upright on a sturdy mug with its filter cap attached before adding water. Pour and stir 0:00–0:10, steep to 1:10, then press to 1:40. Makes one strong cup — dilute with hot water for Americano style.
What you need
- AeroPress unit — the chamber, plunger, and filter cap. That's it.
- Filters — paper filters (included) produce a cleaner, brighter cup. Metal filters let more oils through for a heavier body. Start with paper.
- Scale — eyeballing coffee weight leads to inconsistent results. A cheap digital scale is enough.
- Timer — your phone works fine. The AeroPress timer on this site has the phases built in.
- Kettle — any kettle works. A gooseneck gives you better pour control but is optional for AeroPress since you're pouring into a chamber, not over a bed of grounds.
- Mug or server — the AeroPress presses directly onto whatever you brew into. Make sure it's stable on your surface.
Standard vs inverted method
Standard method: filter cap on, AeroPress sitting upright on your mug. You pour water in, steep, then press down. This is the method this recipe uses. It's simpler, less risky, and easier to learn on.
The manufacturer discourages the inverted method because an unstable brewer can tip and spill hot liquid, causing burns. This guide uses the ordinary filter cap and upright chamber of the AeroPress Original. Check your model’s instructions and capacity; this is not a recipe for every accessory or model.
Grind and ratio guide
Grind size
AeroPress is forgiving but grind size still matters:
- Medium-fine (like table salt) — the default for this recipe. Balanced extraction, easy to press.
- Finer — increases extraction speed and pressure. You get a more concentrated, espresso-adjacent cup. Harder to press. Use with shorter steep times (30–45 s).
- Coarser — faster flow, lighter body, cleaner finish. Extend steep time to compensate.
If your cup tastes sour, grind finer or steep longer. If it tastes bitter, grind coarser or reduce steep time.
Ratio
The standard range for AeroPress is 1:13 to 1:17 (coffee to water by weight).
- 1:13 (e.g., 15 g coffee / 195 ml water) — strong and concentrated. Good as-is or as a base for milk drinks.
- 1:14 — this recipe's default. Full-bodied but not overwhelming.
- 1:17 (e.g., 15 g coffee / 255 ml water) — lighter, more like a long black. Good for subtle single-origin coffees.
Step by step
- Separate chamber and plunger. Put a paper filter into the cap, rinse it if desired and discard rinse water. Twist the cap securely onto the empty chamber.
- Stand the chamber upright on a sturdy, correctly fitting mug, on a stable counter. Add 15 g of medium-fine coffee. Keep the assembled brewer on the mug throughout brewing.
- Start the timer with the first water. Pour 210 g of water at 88 °C and stir gently within the first 10 seconds. Do not fill above your brewer’s capacity.
- Insert the plunger seal slightly into the top to reduce drip-through; do not press yet. Steep until the timer reaches 1:10 (60 seconds after the pour-and-stir phase).
- Press gently and steadily for about 30 seconds, finishing near 1:40. Stop if pressing requires force. Keep hands clear of hot liquid.
- Let the cap cool before removal. Decant the coffee and add dilution water only if wanted. Clean the brewer according to its own manual.
Some liquid may drip through during an upright brew; do not flip a filled brewer to avoid it. Run the AeroPress timer.
Troubleshooting
Too weak or watery — check your dose (15 g is this recipe’s starting dose), grind finer, or extend steep to 75–90 s. If diluting with hot water for Americano style, use less water.
Too bitter — grind coarser, reduce steep time by 15 s, or drop water temperature to 85 °C. Consider roast bitterness as well as extraction.
Sour or underdeveloped — grind finer or add 15–20 s to the steep. A sharp, thin cup can suggest insufficient extraction, but roast acidity also matters.
Grounds in the cup — the paper filter may have shifted or torn. Rinse the filter before use and make sure it's seated flat in the cap. If using a metal filter, some fine particles will always get through — that's normal.
Hard to press — grind is too fine, or you're pressing too fast. Use medium-fine, not espresso-fine. Press slowly with steady downward weight, not a forceful push. If it's genuinely stuck, ease off and check grind size next time.
Packing for travel
Check that your model, cap, filter and mug fit securely together. Pack a way to weigh coffee and obtain suitable drinking water. Materials and capacity vary by AeroPress model; inspect the brewer for damage and follow its manual. A portable brewer still needs a stable surface for hot-water use.
Common questions
Why is AeroPress sour? Grind too coarse or steep too short — add 15 s or grind finer.
Can I make espresso with AeroPress? It's concentrated, not true espresso — use more coffee, less water (1:6–1:10) for a shot-like cup.
AeroPress vs French press? AeroPress = cleaner, faster; French press = heavier body. See the AeroPress vs French press comparison.

CoffeeMethods adapts the dose, water temperature and immersion schedule: 210 ÷ 15 = 14, and 10 + 60 + 30 = 100 seconds. These are editorial choices, not the manufacturer’s complete recipe or results of our own physical testing. The amount of beverage collected is less than the water added.
