Coffee Experts

Chemex is an iconic coffee maker created by chemist Peter Schlumbohm in 1941. Its elegant hourglass design is not only beautiful but functional — thick paper filters provide an exceptionally clean cup.

What You'll Need

  • 6-cup Chemex
  • 30 grams freshly roasted coffee
  • 500 ml water (93-96°C)
  • Scale and timer
  • Gooseneck kettle

Step-by-Step Recipe

1. Preparation (0:00)
Fold the filter and place it in the Chemex with the triple-folded side toward the spout. Rinse with hot water and discard.

2. Bloom (0:00 — 0:45)
Add ground coffee and pour 60 ml of water in circular motions. Let the coffee "bloom" for 45 seconds.

3. Main Pour (0:45 — 3:00)
Slowly add water in a spiral pattern from center to edges. Maintain water level 2-3 cm above the coffee bed.

4. Finish
Total brew time should be 4-4:30 minutes. Remove the filter and enjoy!
