Equal parts brilliance and common sense
The Chemex remains a staple in every coffee enthusiast’s arsenal and its design has endured, unchanged (wood handle, leather cord, tapered glass and all), since its invention in 1941 — a true testament to its genius! Here’s our Chemex brewing guide for a smooth flavorful coffee.
With the Chemex method it’s more important to wet your filter than with any other brewing device. This is because the way the filter sticks to the sides of the Chemex to regulate airflow is paramount to its design.
If you’ve thoroughly wetted the filter, you should be able to pour the water through the spout without the Chemex filter falling out.
Grind: Medium fine
Water Temp: 185°F / 85°C
Brew ratio: Approx. 1:16
Brewing time: 3mins 45secs
Pour the water into your kettle and bring to the boil. Set aside to let cool.
While the water heats, grind your coffee to medium-fine and set aside. Place the filter into the Chemex and set it onto the the scale. Now zero your scale.
To bloom your coffee, start the timer and very slowly pour 70g of water evenly, in concentric circles, making sure to thoroughly wet all your grounds. This should take at least 20 seconds. Stop when your timer reads 0:45.
Slowly keep adding water to the bed, starting from the center and working outward in a small circular spiral until the scale reads 200g. Here you wont be pouring as slowly as you did for the bloom!
When you reach the edge, take 2 laps around, taking care not to hit the sides. Now, start pouring in the same circular motion towards the center of the bed until the scale reads 400g. Your timer should read 2:00.
Take another quick lap around the edge and continue pouring towards the center in circles until your scale finally reads 500g and the timer reads 2:30.
Let gravity do its work and draw the water through the grounds into the bottom of the Chemex. This should take about 75 seconds and your timer should now read 3:45.
Remove and discard the filter. Why not go green and add the grounds to plant soil.
Step 08. Sit back, pour and relax
Pour your coffee into preheated cups and enjoy!
