The Chemex brewer was invented in 1941 by a German chemist and the original design is enshrined in the Smithsonian and MOMA NY. It also happens to brew a pretty darn good cup of coffee.

 

 

 

Step 1

Bring water to a boil.

 

 

Step 2

Grind 30 grams coffee to a medium grind size.

 

 

 

Step 3

Position Chemex filter in 6 cup Classic Chemex brewer. Chemex filters are unique; position the thick side of the filter towards the pouring spout. Rinse filter with hot water. This will remove paper notes and will preheat your brewing equipment. Pour out rinse water.

 

 

 

Step 4

Put the Chemex brewer, filter and coffee on the scale and zero (tare) the scale. Pour enough water on the grounds to wet them, but not enough to start the drip (about 35-50 grams.) Wait 30 seconds. This will pre-wet and bloom the coffee allowing for a better, more even extraction.

 

 

Step 5

Lift the Chemex a couple inches off of the table and gently drop it back onto the table. This will push the grounds off the side of the brewer and down towards the bottom of the filter.

 

 

Step 6

Resume pouring a total of 450 grams of water into the brewer and over coffee grounds. Remove the filter and enjoy!

Total brew time:  

4 minutes

Pro tips:

Use a scale for a consistent coffee/water ratio.

Chemex filters are less porous than other filters resulting in a longer extraction time. Thus, the grind size should be medium-coarse. 

Use hot water right off of boil - approximately 195-205 degrees.
