The Chemex brew

The Chemex filter papers are thicker than most of their competitors. They filter out oils and fine particles creating a cleaner flavour. In this Brew Guide, we will be using the 6-cup Chemex with a brew ration of 60g coffee to 1l of water.

What you'll need
  • Chemex 6 cup
  • Kettle
  • Scales
  • Timer
  • 45g Coffee (coarse grind)
  1. Step One

    Insert the Chemex filter paper making sure the thickest part of the paper is over the spout (if the paper slips into the spout during the brew process it can create an air pocket within the Chemex brewer that reduces the flow rate).

  2. Step Two

    Rinse the paper with boiling water to heat the brewer to remove any paper taste. Discard the water, place on the scales and tear to zero. Add 45g of coffee, start the timer and pour around 90-100g of water over all of the ground coffee. Wait for 30 seconds.

  3. Step Three

    Once the timer reads 30 seconds, the blooming stage is complete and we can add more water. Pour water in a spiralling motion until the scales read 420g.

  4. Step Four

    When the timer reads 1:45, begin another pour in the same fashion as step two. Pour until the scales read 795g.

  5. Step Five

    Now simply wait until all the water has filtered through the coffee. This should take around 3 – 4 minutes. (If you find your brew times are too long or too short, adjust your ground coffees coarseness)

  6. Step Six

    Discard the filter paper and ground coffee. Give the Chemex a quick swirl and pour the coffee. Enjoy!
