Chemex coffee brewing guide

Invented by the eccentric chemist Dr. Peter Schlumbohm in 1941, the Chemex was one of hundreds of inventions he developed. It's simple and effective design has seen it displayed at the Museum of Modern Art in New York, but we love it for it's function and coffee brewing prowess! The all in one hour glass shape means brewing and serving your coffee is simple and easy with just one vessel required for a great brew.

What you'll need;

  • Scales
  • Stirrer
  • 3 Cup Chemex
  • Chemex Filter
  • 320ml fresh filtered water
  • Kettle
  • 20g of Coffee ground medium/coarse
  1. Fold the filter paper and place the thick side facing the spout, preheat with hot water.
  2. Once heated, discard the water and add the coffee. Place on scales and tare.
  3. Begin pouring double the amount of water as there is coffee (for 20g, pour 40g of water), starting in the middle and pouring outward. You'll notice the coffee begin to expand or 'bloom' allow this to continue for 45sec.
  4. Now begin to pour 150g water, again from the centre moving slowly outward to saturate all the coffee grounds, careful not to pour directly on the filter.
  5. Once the water level drops a bit, pour the remaining water as before.
  6. Once most of the water has filtered through, discard the coffee and filter. It should take around 3-3.5 minutes from start to finish.
  7. Sip at your leisure!
