Step by step instructions for making coffee using a Chemex
- Heat the water to 96 degrees Celsius by bringing it to a boil and letting it sit for 30 seconds
- Fold the Chemex filter and insert it on top of the Chemex brewer, making sure the layer side is lined up with the pouring spout
- Pour hot water around the inside of the filter for about 5 seconds. Keeping the filter in place, discard the rinse water. Rinsing the filter with hot water helps seal it inside the dripper, gets rid of any papery taste and heats the Chemex brewer.
- Weigh out 36 grams of beans. Grind them slightly finer than for filter coffee.
- Pour the ground beans into the filter and gently shake the brewer back and forth to ensure that the grounds have settled.
- Start the timer and slowly pour just enough water over the grounds to wet them evenly. Let sit until timer reads 45 seconds. This step is called the ‘bloom’ – the hot water forces the coffee to release trapped gases, leading to expansion of the coffee bed, bubbling at the surface and emitting aromas of coffee.
- Begin pouring continuously in a spiralling pattern until the timer reads 2:45 seconds. If the water level nears the top of the brewer, slow down or pause for a moment. The Chemex brewer has button indicating where the 600ml mark is.
- Allow the water to drain through the coffee. Remove the filter from the brewer and discard the grinds. Pour into mugs and enjoy!
If your brew took more than 4 minutes, the grind was probably too fine. If it took less than 3 minutes, the grind was probably too coarse. Each bean will grind differently depending on its density, humidity and freshness.
