The Chemex was designed by a German chemist, Peter J. Schlumbohm.

A classic and elegant brewing device that is not only good at making a clean cup of coffee but it also can be a decorative piece on any counter. 

  1. Place the filter into the Chemex and pre-wet filter. 
  2. Pour 42g (~6 tablespoons) of fresh ground coffee into filter and settle the coffee bed so it’s even. 
  3. Place Chemex onto scale and tare. 
  4. Start time and slowly pour until all the grounds are saturated or until you reach about 150g. Stir with a spoon to make sure there are no dry clumps. 
  5. Let the coffee bloom for 45 seconds. 
  6. At 45 seconds - slowly pour the rest of the water, up to 450g over the grounds. Make sure the water level stays below ½ inch of the rim. 
  7. At 1:45, fill the brewer flush to the top - this should be about 700g of water. 
  8. At 4:00 minutes you should be done pouring and have about 20 ounces of coffee. Lift the filter and let hover for a few seconds if needed to make sure you have enough volume. Then pull the filter out completely and let it drain into the sink. 

  1. Swirl the Chemex around a little and you are ready to pour about 2 cups of coffee.
