AeroPress recipes vary a lot, so this page uses a clear default: 1:14 for a standard cup. That is 15 g coffee for 210 ml water, 17 g for 240 ml, or 20 g for 280 ml.
For a stronger short brew, keep the dose and use less water in the chamber, then dilute after pressing. For a cleaner cup, stay near 1:14, use medium-fine grind, and press gently instead of forcing the plunger.
After the dose is calculated, open the AeroPress recipe, start the brew timer, and save the ratio in the journal with a note about dilution.
AeroPress ratio FAQ
What AeroPress ratio should beginners use?
Start at 1:14 by weight. It is strong enough to taste full, but not so concentrated that every small grind change becomes harsh.
Can I make espresso with AeroPress?
No. You can make a short, concentrated coffee, but it will not match espresso pressure or crema. Treat it as a strong brew to drink straight or dilute.
