What you’ll need
Chemex Bonded Filter
Water off the boil
If your Chemex filter is not pre-folded, fold it twice into four quarters. Once folded, open the filter into a cone with three layers on one side and one on the other. Put the filter into the Chemex with the three layered side facing the channel (spout). Rinse the filter with water just off the boil (about 205°F). This will eliminate any paper flavor and heat up your Chemex. Discard the rinse water when finished.
Measure and grind 60g (20g per cup) of whole bean coffee. Grind the beans on medium (24-28 on a Baratza style grinder). Add coffee grounds to the Chemex. Shake it softly to level the grounds at the bottom of the filter.
Start the timer and add pour in water just off the boil (about 205°F) slowly in concentric circles to saturate the grounds. Avoid pouring directly on to the filter. The water should be just enough to cover the grounds. Let the grounds sit for 40 seconds to allow the gases to release. This process if called “blooming.”
After 40 seconds, pour the remaining water slowly and continuously, in concentric circles, over the grounds. Pour until the water reaches about a half inch from the rim. Let it sit for a few seconds and pour any remaining in. To get an even saturation, pour over the dark areas and avoid the lighter ones.
Once 900g of water has been added, stop pouring and let the water drip. Once the water drains into the Chemex you should be left with a flat bed of grounds. The entire brewing process should take 6 minutes (about 2 minutes per cup). Discard the filter and enjoy!
