Learn how to brew coffee using the Chemex

Chemex Brew Guide

Timeless method for crisp and clean flavor


  • Recommended coffee-to-water ratio 1:16
  • For 2 to 3 cups: 40g coffee to 640g water. (1ml of water = 1g)

You will need

  • Chemex
  • Chemex filter
  • Scale
  • Grinder
  • Kunjani coffee (whole bean)
  • Kettle
  • Water
  • Timer


  1. Place your filter into the Chemex and rinse with hot water. This will remove the papery taste and preheat your Chemex. Discard water prior to adding coffee grounds.

  2. Heat your water kettle to 200-205°F (about 90 second off boil).

  3. Weigh out the proper amount of coffee beans and grind them on a medium-course setting.

  4. Set the Chemex on top of your scale and zero (tare) it.

  5. Set a timer and begin pouring about 50g-75g of water over the coffee grounds, enough to saturate all of the coffee. Bloom for 30 seconds.

  6. Start pouring water in a constant circular motion and continue until the appropriate amount of water has been added. Take your time, all coffee should have passed through the filter by 3:30 to 4 minutes.

  7. Discard filter and serve.
