The AeroPress has no fixed recipe because it has no fixed purpose. The same tube makes something close to espresso, something close to filter coffee, and a strong short drink in between — and all three are legitimate. What changes is the ratio, and secondarily the grind and the steep time.
Three ratios, three drinks
Pick the drink first, then the ratio follows. This is the opposite of most brew methods, where the ratio is fixed and the drink is whatever comes out.
| Style | Coffee | Water | Ratio | Grind |
|---|---|---|---|---|
| Concentrate / faux espresso | 18 g | 60 g | 1:3.3 | Fine |
| Strong short cup | 15 g | 150 g | 1:10 | Medium-fine |
| Standard cup | 15 g | 225 g | 1:15 | Medium |
| Long black / iced | 18 g | 270 g | 1:15 + dilution | Medium-coarse |
The concentrate method
Load 18 g of fine grind. Pour 60 g of water at 90C, stir five times, steep 60 seconds, then press slowly for 30 seconds. You get roughly 50 g of very strong liquid in the cup.
Dilute with 120 to 150 g of hot water to taste. This is the closest the AeroPress gets to espresso, and the reason the inverted method exists — it lets you steep without dripping through the paper before you are ready.
It is not espresso. There is no pressure valve and nowhere near nine bars. But it is strong, syrupy and works as a base for milk drinks, which is what most people actually want.
The standard cup
15 g at medium grind, 225 g of water at 85 to 90C. Pour all the water, stir once, steep 90 seconds, press slowly for 30 seconds. Total time around two and a half minutes.
This is the recipe to learn first. It is forgiving of small errors, uses an ordinary medium grind, and produces a clean cup closer to filter coffee than to espresso. Once this is repeatable, move to the concentrate if you want something stronger.
Water temperature
The AeroPress community spent a decade arguing about temperature and settled on: it matters less than grind and ratio. Use 85 to 92C for dark roasts, 90 to 95C for light roasts. Boiling water works fine and is what the manufacturer recommends.
If your coffee tastes harsh or ashy, drop the temperature before you change anything else. Dark roasts extract bitter compounds fast, and the AeroPress has a lot of contact time.
Inverted or standard
Standard orientation drips a little before you press. With a fine grind and a short steep that barely matters. With a coarse grind and a two-minute steep, you lose enough water that the ratio drifts.
Inverted means you brew upside down and flip before pressing. It holds everything in place, which makes timing exact. It is also more likely to spill hot coffee on your hand. Use it for the concentrate method, skip it for the standard cup.
- Standard: simpler, safer, fine for medium grinds and short steeps
- Inverted: exact timing, needed for fine grinds and long steeps
- Either way, rinse the paper filter first to remove paper taste
Common mistakes
- Pressing too hard — pressure channels through the puck and produces an uneven extraction
- Grinding too fine for a long steep — the press becomes hard to push and the cup turns muddy
- Not stirring — the AeroPress needs one stir to saturate the grounds evenly
- Using a 1:15 ratio with an espresso grind and expecting espresso — it will just be a slow, bitter cup
