AeroPress: The Travel-Proof Coffee Maker
Why the AeroPress
The AeroPress is a plastic tube with a plunger. You steep coffee in it, then press it through a small paper filter with your hand. It was invented by Alan Adler, the engineer behind the Aerobie flying ring, and went on sale in 2005. It has since become one of the most loved coffee makers in the world.
People love it because it is:
- Fast: about two minutes.
- Forgiving: hard to make a bad cup.
- Tough and light: plastic, nearly unbreakable, great for travel and camping.
- Clean-tasting: the paper filter catches oils and grit, like pour-over , but with more body.
- Cheap: one of the least expensive good brewers.
It makes one cup at a time.
Standard or Inverted
| Standard | Inverted | |
|---|---|---|
| How | Chamber sits on the mug, filter at the bottom | Upside down: plunger at the bottom, flipped onto the mug before pressing |
| Pro | Simple, safe | No coffee drips through during the steep |
| Con | Some coffee drips through early | Flipping hot coffee can spill or burn |
| Best for | Beginners | People who want full-immersion control |
Start with the standard method below. Newer AeroPress models with a flow-control cap solve the drip problem without flipping.
The Recipe
| Coffee | 15 g |
| Water | 220 g (about 1:15) |
| Water temperature | 205 °F (96 °C) for light roasts, 195 °F (90 °C) for dark |
| Grind | Medium-fine, a little finer than pour-over |
| Total time | About 2 minutes |
Steps
- Put a paper filter in the cap, rinse it with hot water, and twist the cap onto the chamber.
- Set the AeroPress on a sturdy mug and put both on your scale.
- Add the coffee and zero the scale.
- Pour 220 g of water quickly, making sure all the grounds are wet.
- Stir 3–4 times.
- Put the plunger in about 1 cm (½ in) to stop the dripping, and wait until 1:30.
- Press gently and steadily for about 30 seconds. Stop when you hear a hiss.
Make It Your Own
The AeroPress is famous for endless recipes; there is even a World AeroPress Championship. Some easy variations:
- Concentrate for milk drinks: 18 g coffee, 90 g water, fine grind, press after 1 minute. Top with hot or cold milk for a strong latte-style drink. It is not espresso, but it is close enough for many people.
- Iced coffee: brew the concentrate straight onto a glass full of ice.
- Stronger or weaker: change the water, not the time.
Tip: If pressing feels very hard, your grind is too fine. Never force it; you can crack the chamber or spray hot coffee.
Fixing Your Cup
| Tastes… | Try |
|---|---|
| Sour or thin | Grind finer, use hotter water, or steep 30 s longer |
| Bitter or dry | Grind coarser or use cooler water |
| Weak | Add 1–2 g of coffee |
Cleaning
Unscrew the cap and push the plunger over the trash or compost: the grounds pop out in a neat puck. Rinse the rubber seal and you are done. Store it with the plunger pushed all the way through so the seal is not squashed.
Is It for You?
Choose the AeroPress if you make one cup at a time, travel, or want to experiment. If you brew for several people, a French press is easier.
