How do you brew AeroPress coffee?
Quick answer
15 g coffee, 210 ml water (1:14), water 88 °C (190 °F), medium-fine grind. Pour, stir 10 s, steep 60 s, press over 30 s. 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.
Inverted method: the plunger goes in first, AeroPress sits upside down on the plunger. You steep with the opening facing up, then flip the whole thing onto your mug and press. It gives you more control over steep time because no liquid drips through prematurely. The trade-off: if you fumble the flip, you lose the brew.
Recommendation: start standard. Once you're comfortable with the timing and pressure, try inverted if you want to experiment. The flavor difference is small — consistency matters more at first.
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.
Why AeroPress extracts well in less time
Most brew methods rely on gravity or passive diffusion — water sits on grounds and slowly pulls out flavors. AeroPress adds a third variable: pressure. When you press the plunger, you force water through the grounds faster and more completely than gravity alone.
This matters for two reasons. First, it shortens brew time to under two minutes without sacrificing extraction. Second, it lets you use lower water temperatures (85–90 °C instead of 93–96 °C) without under-extracting, which reduces bitterness and makes the cup smoother. The combination of pressure, agitation (the stir), and immersion gives you more extraction levers than almost any other manual method.
Step by step
- Insert paper filter into cap, rinse with hot water, discard rinse water.
- Add 15 g of medium-fine ground coffee.
- Start timer. Pour 210 ml of 88 °C water in 10 seconds, saturating all grounds.
- Stir gently 2–3 times. Attach cap (standard method).
- At 1:00, place AeroPress on mug and begin pressing steadily.
- Press over 30 seconds. Stop when you hear a hiss — that's air, not more coffee.

Troubleshooting
Too weak or watery — check your dose (15 g is the floor for a single cup), 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. Bitterness usually means over-extraction.
Sour or underdeveloped — grind finer or add 15–20 s to the steep. Sourness means under-extraction.
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.
Why AeroPress is great for travel
The AeroPress is one of the best travel brewers for three reasons:
- Durable — it's made from BPA-free copolyester plastic. You can drop it, pack it into a checked bag, and bring it on a plane without worry. No glass, no ceramic, nothing fragile.
- Lightweight and compact — the plunger nests inside the chamber. The whole unit plus a stack of filters fits in a jacket pocket.
- Forgiving — hotel kettles run too hot, tap water is inconsistent, and you're often guessing on grind from a local shop. AeroPress handles variation better than pour-over because immersion and pressure compensate for small errors. You'll get a decent cup even when conditions aren't ideal.
It also works without electricity (beyond the kettle), making it useful for camping, road trips, or any situation where a full coffee setup isn't practical.
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.
