Coffee 101: How to Brew Coffee in a Chemex

Aug 20, 2019 | Coffee, Coffee & Tea 101


First things first: What is a Chemex, anyway?

Invented in 1941, the Chemex is an easy to use, no-frills infusion brewer, which nonetheless has been recognized by museums and coffee aficionados for its exquisite aesthetics and engineering perfection.

Filters for the Chemex are significantly thicker than those for other pour over methods. Together, brewer and filter yield a rich, clean, sediment-free brew – if at a slightly slower pace.

What You Will Need

To brew coffee in a Chemex, you’ll need to assemble the following materials and tools.

  • 3 cup Chemex brewer
  • Square filter
  • 5-7 Teaspoons of Orinoco coffee beans
  • 600 ml of water
  • Gooseneck kettle
  • Timer
  • Scale
  • Burr grinder (recommended)

Commence Your Chemex Brewing!

Follow these simple steps for a fresh, rich cup of Chemex-brewed Orinoco coffee!

  1. Heat water to 205º (hint: bring to boil and allow to sit for approximately 30 seconds)
  2. Place your Chemex brewer on your digital scale.
  3. Insert filter into the top of the Chemex brewer. Be sure the 3-layered side is facing the spout.
  4. Rinse the inside of the filter by pouring water in a circular motion for approximately 5 seconds. This helps the filter to settle properly. Discard the rinse.
  5. Immediately before brewing, grind your coffee. Aim for a grind that is slightly coarser than medium (about the consistency of sea salt).
  6. Place the coffee in the filter and give a slight shake to allow grinds to settle.
  7. Start your timer.
  8. Slowly, begin pouring water over grinds, evenly saturating. Allow mixture to set until timer reaches 45 seconds. Watch and smell (and “ooh” and “ahh”) as your coffee blooms.
  9. Continue pouring your water in a spiral pattern, making sure not to pour directly in the center, or on the outer rims, of the filter. Should water reach the rim, pause and allow it to soak into the grinds. When your timer reaches 2:45, cease pouring (or when your scale reaches 600 grams).
  10. Allow the coffee to drain through. This should take approximately 45 seconds. (If not quite, or beyond, that estimate – your grind was likely too fine and/or coarse. Adjust accordingly next time!)
  11. Remove filter and grinds and toss.
  12. Pour into a mug and enjoy!
