The most forgiving brewer ever made.
Immersion plus pressure plus a paper filter. Almost impossible to make undrinkable coffee with, endlessly adjustable, and it fits in a bag. If you own one brewer, own this one.
16g of coffee, 230g of water at 90°C, medium-fine grind, steeped 90 seconds, pressed over 30. That is the standard method and it works with almost any coffee.
Standard — upright
16g : 230g · 2:00 · 90°CInverted — more control, more body
18g : 220g · 2:30 · 88°CAdjusting for the coffee
| Coffee | Temperature | Steep | Why |
|---|---|---|---|
| Light, washed, acidic | 92–94°C | 2:00 | Needs heat and time to open up |
| Medium, balanced | 90°C | 1:30 | The default |
| Dark, roasty | 82–85°C | 1:00 | Lower heat keeps the bitterness down |
| Natural, fruity | 88°C | 2:30 inverted | Longer immersion pulls out the fruit |
Concentrate and dilute
For something closer to espresso — or a base for an iced latte — brew 20g of coffee in 90g of water, medium-fine, steeped 90 seconds. That gives you a small, intense shot you can dilute to taste. It is also the trick for making an AeroPress americano in a hotel room.
Metal filter or paper?
Paper gives you a cleaner, brighter cup and is what most recipes assume. A metal filter lets the oils through for more body and texture, at the cost of some clarity and a little sediment. Paper is the better default; keep a metal disc for travel so you never run out.
Questions
AeroPress, answered.
What is the best AeroPress ratio?
16g of coffee to 230g of water for a full mug, or 20g to 90g for a concentrate you dilute afterwards. The AeroPress is unusually tolerant — anywhere from 1:12 to 1:16 produces good coffee.
Standard or inverted?
Inverted gives you complete control over steep time and slightly more body, because nothing drips through while brewing. Standard is faster, safer and produces a cleaner cup. Start standard; move to inverted when you want to experiment.
What grind size for AeroPress?
Medium-fine — a little finer than pour-over, noticeably coarser than espresso. If pressing takes real effort, go coarser.
Why does my AeroPress coffee taste bitter?
Usually the water is too hot or you pressed past the hiss. Drop to 85–88C for darker roasts and stop pressing as soon as you hear air. A grind that is too fine will also over-extract.
