CBRC Chemex Brewing Guide
Want to try your hand at brewing coffee like Roastmaster Paul? Consult the below CBRC Chemex Brewing Guide!
The Chemex Coffeemaker was invented in 1941 and is an hourglass-shaped glass flask with a conical funnel-like neck. It uses proprietary filters made of bonded paper that remove most of the coffee oils that occur while brewing, leaving the coffee with a very clear taste that is different compared to traditional brew methods.
- Step 1: Start water boiling in a kettle, you want it to be about 205 degrees.
- Step 2: Weigh 38 grams of coffee - approximately 5 tablespoons
- Step 3: Place paper filter into the Chemex with the three layer folded side over the pour spout.
- Step 4: Pre-rinse the paper filter with some of your hot water to avoid a papery taste in the final coffee brew and to preheat the cup.
- Step 5: Dispose of pre-rinse water, pouring it out of the Chemex.
- Step 6: Grind the 38 grams of coffee slightly coarser than drip grind (like coarse salt) and put grinds into the filter, shaking it slightly to settle the grinds.
- Step 7: Place the Chemex on a scale and tare out to 0 grams. Start a timer and begin to pour, in a circular motion, saturating the grinds until the scale reads 150 grams. Make sure to saturate all of the grinds before getting to the 150g. Pouring slower will help you saturate more grinds before getting to the stopping point. This step is called the bloom. Hot water forces the coffee to release gases, leading to bubbling at the surface and wonderful aromas for you to enjoy.
- Step 8: At 45 seconds, start to saturate the grinds again, pouring in a circular motion. If the water level nears the rim of the Chemex, pause for a moment to let it drain before continuing. Stop pouring once your timer reads 2:45 or your scale reads 600 grams and allow all the water to drain through the filter. The volume should reach, or be close to, the 20oz glass bubble marker on the Chemex body.
- Step 9: Once it finishes, remove the filter and discard the grounds.
- Step 10: Enjoy the Coffee!
While Paul could probably do this in his sleep, don't forget, practice makes perfect. The more you brew, the more comfortable to you will be with the process!
