How to brew

The Chemex is an elegant all-glass hourglass brewer that uses specialty bonded filters up to 30% thicker than standard pour-over papers. Those dense filters absorb the heavier oils, fats and fine particles, producing an exceptionally clean, bright cup — and it brews enough for several people at once.

Step by step

  1. Open the folded filter and place it in the top cone with the three-layer side against the pouring spout — this stops the thick paper collapsing into the air channel.
  2. Rinse the filter thoroughly with hot water to remove papery flavour and warm the glass, then pour the rinse water out through the spout.
  3. Add 30g of medium-coarse coffee, pour 100g of water for the bloom, and wait 45 seconds.
  4. Pour the remaining water in steady, outward spirals to 500g, keeping the water level about 1cm below the rim.
  5. Let it draw down fully, then lift out and discard the filter. Aim to finish around 4:00–4:30.

Because the thick filter slows flow, a slightly coarser grind than a V60 keeps the brew from stalling while preserving that signature clarity.

Troubleshooting

  • Sour or thin? Grind finer, brew hotter, or pour a little more slowly.
  • Bitter or harsh? Grind coarser or cool the water slightly.
  • Stalling or very slow? Grind coarser, and make sure the three-ply side sits against the spout so air can escape.
  • Papery taste? Rinse the thick filter more thoroughly before brewing.
