AeroPress Coffee Recipe: The Perfect Ratio
The AeroPress is one of the most forgiving ways to make a genuinely great cup of coffee. It is quick, easy to clean, almost impossible to mess up, and it travels well. But if you want to go from good to consistently excellent, it all comes down to one thing: your coffee-to-water ratio.
The best AeroPress ratio
A great starting point is 1:14 — that is 1 gram of coffee for every 14 grams (millilitres) of water. For a standard AeroPress cup, try 15g of coffee to 210ml of water. Prefer it stronger and more concentrated? Move towards 1:12. Like it lighter and more tea-like? Ease out to 1:16.
Not sure how to scale that to your mug or a bigger brew? Our AeroPress ratio calculator does the maths for you — set your coffee or water amount and it works out the rest, along with the grind and steps.
What you will need
- AeroPress and a fresh paper filter
- 15g of freshly ground coffee (medium-fine, like coarse table salt)
- 210ml of water at 80–85°C for dark roasts, up to 90–94°C for lighter roasts
- A scale, and a timer if you have one
Step-by-step AeroPress recipe
- Insert a paper filter into the cap and rinse it with hot water. This removes any papery taste and warms the brewer.
- Add your 15g of ground coffee to the chamber and give it a gentle shake to level the bed.
- Start your timer and pour in all 210ml of water. Stir three to five times so every ground is saturated.
- Pop the plunger in just enough to create a seal and let it steep for one minute.
- Press down slowly and steadily over about 30 seconds. Stop as soon as you hear a hiss — that means you have reached the coffee bed.
The whole thing takes under two minutes, and cleanup is a single push of the puck into the bin.
Dialing it in
If your coffee tastes sharp or sour, your water was probably too cool or the grind too coarse — try a touch hotter or finer. Bitter or harsh? Grind a little coarser or drop the temperature. Small changes make a big difference with the AeroPress, so adjust one thing at a time.
Bean choice matters too. A bright single origin will shine at a lighter ratio, while a chocolatey blend holds up beautifully around 1:13 to 1:14 with a splash of milk.
Want to Try James Hoffmann's Recipe?
Our 1:14 starting point is a great all-rounder, but if you would like to brew the way former World Barista Champion James Hoffmann does, give the James Hoffmann AeroPress recipe a go. It uses a gentler 1:18 ratio, skips rinsing the filter, and swirls rather than stirs for a clean, sweet, repeatable cup. It is loaded and ready in our Brew Guide and Ratio Calculator, so you can scale it to any size and follow the steps.
The cost of brewing at home
Here is the part your wallet will like. A cafe flat white runs about $5 to $6; an AeroPress cup at home, once you have the beans, costs closer to $1. Over a year, that adds up fast.
