Brewing filter coffee may look straightforward but small details make a big difference to the final cup.
By following a consistent method and respecting brew ratios and timing, you’ll achieve a balanced, flavourful coffee every time.
Here’s how to brew filter coffee properly.
1) Use One Filter Paper Only
Filter papers can easily stick together, so always double-check that you’re using just one. Multiple papers restrict water flow, leading to under-extraction and poor flavour.
Place the filter paper neatly in the centre of the brew pan, pressing the sides firmly against the pan.
2) Follow the Correct Coffee-to-Water Ratio
The recommended recipe from the Specialty Coffee Association is:
-
56.7 g of ground coffee
-
1 litre (1,000 ml) of water
Using pre-measured sachets ensures consistency. Measure your water carefully – one litre corresponds to the number 10 mark on standard filter jugs.
Always use cold, fresh water.
3) Level the Coffee Bed
Add the ground coffee to the filter pan, then gently tap the pan to level the bed. This ensures the water flows evenly through the coffee, producing a balanced extraction.
4) Brew for the Right Time
Insert the brew pan into the machine and pour one litre of water into the top. Place the jug underneath to catch the brew.
The brew should take around five minutes. Using a timer helps maintain consistency and quality.

5) Don’t Hold Coffee Too Long
Once brewed, filter coffee should sit on the hot plate for no longer than 40 minutes. Beyond this point, evaporation causes the coffee to become stale, thick, and syrupy, losing its fresh flavour.
6) Always Let the Brew Finish
Never take coffee mid-brew. Coffee extracts in stages:
-
Early: acidity
-
Middle: sweetness and caramel notes
-
Late: bitterness
A well-rounded cup needs all three. Taking coffee before the brew finishes results in an unbalanced flavour.
7) Swirl Before Pouring
Before serving, give the jug a gentle swirl. This mixes all flavour components together, ensuring every cup tastes as good as the last.
The Result
By following these key principles, you’ll produce filter coffee that is:
-
Balanced and consistent
-
Fresh and flavourful
-
Never stale or bitter
Simple steps, done properly, make the difference between average filter coffee and a truly great cup.
