Brewing 101 With CHEMEX
How to Brew the best cup you have every time you have it
Like all good things, full flavor takes time — and your own special touch. The CHEMEX® Coffeemaker delivers only the elements essential to rich coffee flavor, so that your personal taste and approach shine through.
Step 1: Get into the grind
Grind your favorite whole bean coffee to a medium coarse ground.
Optional Tip: We suggest using a burr grinder because it delivers a more consistent particle size, allowing for a more even extraction and fuller bodied cup of coffee.
Step 2: Filter up
Open a CHEMEX Bonded™ Filter into a cone shape so that one side of the cone has three layers, and place it into the top of the CHEMEX® brewer. The thick three-layer portion should cover the pouring spout.
Optional Tip: Dampen the filter with warm water to rinse and preheat the brewer. Once the water has drained through the filter completely, pour it out of the brewer while keeping the filter sealed against the coffeemaker wall.
Step 3: The scoop
Put one rounded tablespoon of ground coffee for every 5 oz. cup into the filter cone. Feel free to use more if you prefer it stronger; our CHEMEX® brewing process eliminates bitterness.
Tip: On all brewers except the pint size model, the “button” indicates the carafe is half filled and the bottom of the wooden collar/spout indicates it's full. On the pint size brewer, the button is the full marker.
Step 4: Let it bloom
Once you have brought the appropriate amount of water to a boil, remove it from the heat and allow it to stop boiling vigorously. Pour a small amount of water in a circular motion over the coffee grounds to wet them, and wait for about 30 seconds for them to “bloom”.
Optional Tip: The “bloom” is escaping gas that has been trapped in the beans during the roasting process. You will see the grounds inflate and bubbles appear on their surface as the flavor inhibiting gas expels upward. Once this is complete, water can freely extract the aromatics and coffee oils while brewing.
Step 5: First pour
After the grounds bloom, slowly pour the water over the grounds while keeping the water level well below the top of the CHEMEX® Coffeemaker (quarter inch or more).
Step 6: Brew on
Slowly pour the remaining water over the grounds, using a circular or back-and-forth motion as you pour to ensure an even saturation of the coffee.
Step 7: Toss the filter
Once the desired amount of coffee is brewed, lift the filter with spent grounds out of the brewer and discard.
Step 8: Enjoy the perfect cup
Pour your freshly made coffee into your CHEMEX® mug and indulge in the flavor.
