The Chemex coffeemaking system was developed by a chemist to achieve one result ... Brew A Perfect Cup of Coffee Every time.

The keystone of the Chemex method is the fractional extraction of only the desirable parts of the coffee bean. Fractional extraction at 190-200 Fahrenheit leaves the coffee fats and bitter elements in the coffee grounds, not in your cup. Chemex-bonded filters and the proper brewing method make this possible.

  1. Step One: Open the Chemex-Bonded® Coffee Filter into a cone. One side should have three layers. Place the cone in the top of your coffeemaker with the thick portion toward the pouring spout.
  2. Step Two: Using Regular or Automatic Grind coffee only, put one rounded tablespoon of coffee per 5 oz. cup into the filter cone. If you prefer stronger coffee, use more; there is never any bitterness in coffee brewed using the Chemex® method.
  3. Step Three: When the water is boiling, remove it from the heat until it stops boiling vigorously. It should now be at about 200°F, a perfect brewing temperature. Pour a small amount of water over the coffee grounds, just enough to wet them without floating. This is important because it allows the grounds to "bloom," so the desirable coffee elements can be released.
  4. Step Four: After this first wetting simply pour more water, soaking the grounds each time, but keeping the water level well below the top of the coffeemaker. Once the desired amount of coffee is brewed, dispose of the spent grounds by lifting the filter out of the coffeemaker. And that's it! You are now ready to enjoy a perfect cup of coffee!

Important: Always use regular or medium grind with the Chemex Coffee Filters. Any other grind may affect the filtration rate. We recommend using spring water or purified water for making coffee. The quantity of brewed coffee can be measured in the Chemex Coffee Maker by using the button and handle bottom as guides. Measurements are based on a standard 5 ounce cup. The button marks the halfway point, and the bottom of the handle indicates full capacity.
