Brew Guide: Chemex Brewer
With its sleek and iconic design, the Chemex effortlessly brews coffee for one person or two. The resulting cup is clean-bodied, sweet and vibrant.
What You Need:
8-cup Chemex brewer
44g of coffee
700g hot water just off the boil (about 205° F)
Prep and Preheat:
Place the Chemex filter in the brewer with single fold away from the spout and the three-layered side facing the spout. This will allow air to escape during the brew process. Rinse the filter with hot water to achieve an even seal all the way around. This preheats the brewer and eliminates any paper flavor from the filter. Once thoroughly saturated, tip the Chemex over a sink to dispose of the rinse water. Don’t be tempted to remove the filter to empty faster as it can be difficult to secure into place once removed.
Weigh and Grind Coffee:
Add 44g of coffee ground medium-coarse, similar to Kosher salt. Center the coffee in your brewer and tare the scale to zero.
Start the timer when you begin to add the hot water. The goal is even saturation, so pour slowly in a clockwise pattern. This bloom allows the coffee to de-gas, enabling the water to yield the full potential of the coffee. This is an essential step that should never be rushed. Pour until all the grounds are saturated or until you reach about 150g. Stir with a chopstick or spoon to make certain there are no dry clumps.
Add More Water:
At :45 begin the second pour, being certain to reintegrate the coffee and water. Pour with a wiggling motion, then a gentle spiral until the volume reaches about a fingertip down from the top of the rim or 450g of water. Pour over the dark areas and avoid the light ones.
Allow It to Brew:
Note: For all our brewing methods, we suggest starting with a 1:16 coffee to water ratio which provides an excellent extraction level that maximizes flavor. Feel free to adjust this ratio to achieve a stronger brew if you wish. Should you find that the flavor is stronger than you’d like, however, simply dilute the brewed coffee with fresh, hot water. See our Four Fundamentals to a Perfect Cup for a fuller explanation of the coffee to water ratio under the heading "Proportion."
