Making coffee with an Aeropress

In case you’re not a seasoned Aeropress coffee brewer, you probably don’t know the perfect aka “golden ratio” of coffee to water for this particular way of preparing coffee.

So what is the recommended coffee to water ratio for Aeropress? It’s 1:16, meaning for every gram of coffee grounds, you should use 16g (or rather ml) of water.

This ratio makes for a flavorful cup of coffee that isn’t too bitter. If you use this ratio and Aeropress brew method correctly, you’ll end up with a smooth and delicious cup of coffee every time.

Some people think that 1:16 ratio doesn’t give you a strong enough cup of coffee and use a lot more coffee grounds to prepare their coffee.

A typically sized Aeropress can hold 240ml (8oz) of water. This means that for a single cup of coffee, you should use around 15g (0.53oz) of coffee grounds.

If you want to make a double Aeropress, you should use 30g (or around one ounce) of coffee grounds.
