Chemex

 
 

The CHEMEX® coffeemaker was invented in 1941 by the eccentric chemist Dr. Peter Schlumbohm. Throughout his career he developed over 300 patents, ranging from cocktail shakers to automobiles. His focus was on making everyday objects more functional, attractive and enjoyable to use.

How to make it.

  1. Place the tripled layered section of the filter paper on the spout side of the glass jar.

  2. Give it a rinse through with hot water, then tip away the excess.

  3. Place your ground coffee in the filter paper. Level it out with a gentle shake.

  4. Put it all on the scale.

  5. Start a timer, then pour 50g of water into the grounds, until they’re saturated. Watch them bloom.

  6. After 30 seconds, pour in 200g more water.

  7. Then at 90 seconds, add 200g more.

  8. All your water (450g) should be in by the 90-second mark. Now, let it finish dripping.

  9. After four minutes, your brew should be good to go.
