Brewing decaf at home without overthinking it
10 January 2025
A simple, non-fussy approach to brewing decaf at home — whatever kit you already own.
Sample content — for demonstration only.
The best way to brew decaf is the same as the best way to brew regular coffee: use good beans, use enough of them, and don’t worry too much about the rest.
Cafetière (French press)
- 60g coffee per litre of water, roughly.
- Just off the boil.
- Four minutes, plunge, done.
AeroPress
- 15g coffee, 220g water at about 90°C.
- Stir, wait a minute, press slowly.
- Very forgiving with decaf.
Espresso
- 18g in, aim for 36–40g out in around 30 seconds.
- If it tastes sour, grind finer; if it tastes bitter, grind coarser.
- Decaf beans behave slightly differently — expect to shift the grinder a click or two.
Milk drinks
Barista oat milk and semi-skimmed dairy both work brilliantly with chocolatey decafs. Steam to about 60°C — any hotter and you’ll cook out the sweetness.
