Coffee Water Temperature Brewing Time
22 g 300 ml 95 C  3:00 - 3:30 min.


Whole coffee beans / scale / Chemex coffee maker / coffee filter paper / coffee grinder / kettle / timer / hot water


  1. Grind your coffee slightly coarser than for filter coffee.
  2. In a kettle, heat water (preferably filtered, alternatively drinking water) to 94°C (do not boil the water then leave it to cool).
  3. Place the filter paper into the Chemex, with its thicker (3 layer) portion over the opening.
  4. Rinse the Chemex and filter paper thoroughly with hot water (to remove the smell of paper).
  5. Pour out the water through the narrower part of the Chemex and make sure the paper does not move. There should be no air pockets in the filter paper.
  6. Pour the coffee into the Chemex and tap the edges gently to form a flat bed of coffee.
  7. Place the Chemex on the scale.
  8. Turn on the scale and start the timer.
  9. For the first 20 seconds, quickly and vigorously pour 100 ml of water onto the coffee. Try to pour in concentric rings, from the edges inwards (to naturally agitate the coffee on the bottom and cause it to rise).
  10. After 1 minute, pour another 100 ml of water within 20 seconds. This time, move from the center outwards in concentric circles. Aim for black spots, avoid any white areas.
  11. At 2:00 minutes, add the remaining 100ml of water.
  12. Take care not to pour water outside of the coffee filter paper or it will pour through without brewing the coffee.
  13. The entire process should take 3:00 – 3:30 minutes.
  14. Hold the Chemex from the wooden collar and discard the coffee filter paper.
  15. Gently shake the carafe to ensure the coffee in the Chemex is mixed evenly, and serve immediately in a preheated mug.
  16. Dismantle by removing the wooden collar and wash thoroughly.
