AeroPress Ratio Calculator
AeroPress is the most forgiving brewer you can buy — but the ratio still decides whether the cup is bright or muddy.

Why AeroPress ratios look so strong
AeroPress uses far less water than a drip brewer, so the ratio looks intense on paper: 1:13 for a standard cup. The finished brew is usually topped up with hot water or milk, and short contact time needs more coffee to extract properly.
The compact basket also makes the ratio easy to change mid-brew — you can brew a 1:8 concentrate and dilute it, which is what most World AeroPress Championship recipes do.
AeroPress ratios by style
| Method | Ratio | Why |
|---|---|---|
| Standard | 1:13 | 15 g coffee, 195 g water, 1:30 total. Close to a strong filter cup. |
| Concentrate | 1:6 – 1:8 | Dilute 1:1 with hot water. Competition style, more body and sweetness. |
| Inverted, full immersion | 1:12 | 30 s bloom, stir, flip at 1:00, press 30 s. The most repeatable method. |
| Cold / iced | 1:10 over ice | Brew hot, press directly onto ice. The ice counts toward final weight. |
| Diluted to filter strength | 1:8 plus 100 g water | Concentrate plus bypass water gives a clean, bright, filter-like cup. |
An AeroPress schedule that works
For 15 g coffee at 1:13 (195 g water), 85 °C, inverted:
- Rinse the paper filter, then set the plunger slightly into the chamber, inverted, so the water stays in during the bloom.
- 0:00 — Add 15 g coffee and pour 70 g water. Stir three times, then wait 30 seconds.
- 0:30 — Pour the remaining 125 g and stir gently to level the bed.
- 1:00 — Cap, flip, press. Flip the assembly onto your cup and press steadily for 30 seconds.
- Stop at the hiss. Once air escapes, the puck is dry and pressing further only adds bitterness.
Frequently asked
What is the best AeroPress ratio?
1:13 for a standard cup — 15 g of coffee to 195 g of water, brewed in about 1:30. Stronger competition recipes use 1:6 to 1:8 and dilute after pressing, trading clarity for body.
How many grams of coffee for AeroPress?
15 to 18 g is the sweet spot for the standard chamber. Above about 20 g with the standard method overfills it; the inverted go-everywhere recipe uses 30 g.
AeroPress vs French press ratio?
AeroPress runs stronger per gram of water, 1:13 against 1:15, because contact time is much shorter — 90 seconds versus 4 minutes. French press is more forgiving of a coarse grind; AeroPress is more forgiving of everything else.
Why does my AeroPress taste sour?
Water too cool, or the press is too fast. Sour means under-extraction: go to 90 °C, grind slightly finer, and extend the steep by 15 seconds. Adding more coffee changes strength, not extraction.
