Best Bean: fruity, floral, brightly acidic coffees shine in a Chemex. Go with a blend from Ethiopia or Kenya.
Grind: medium to medium-coarse.
Producing a great cup of coffee with a Chemex is dependent more on proper measuring and timing than it is the expertise of the brewer, making it a great selection for recent converts to manual brewing. Because it uses very thick paper filters, the water flows more slowly through the coffee grounds than with other pour-over methods.
Full-ImmersionRather than gradually pouring water over grounds, full-immersion brewing methods entail completely covering the coffee grounds in hot water and allowing them to steep, extracting flavor along with more of the beans’ natural oils than other brewing methods.
Full-immersion techniques allow the coffee and water to have a more extensive interaction and result in a deep-flavored, robust-bodied cup of coffee.
What you need:
42g ( 6 Tablespoons) of coffee
Hot water just off the boil (about 205°F)
Step 1: Prep and preheat
Place the Chemex Filter in the brewer with single fold away from the spout and multiple folds lined up against the spout. Rinse the filter with hot water to get a nice even seal all the way around. This preheats the brewer and gets rid of any paper flavor from the filter. Dump the rinse water and fold the filter toward the spout to reinforce this area.
Step 2: Weigh and grind coffee
Add 42g or about 6 Tablespoons of coffee ground kind of like Kosher salt. Center the coffee in your brewer and zero out the scale.
Step 3: Saturate grounds
Start the timer when you add the hot water. Pour until all the grounds are saturated or until you reach about 150g. Stir with a chopstick or spoon to make sure there are no dry clumps.
Step 4: Add more water
At :45, start the second pour, making sure 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 spots and avoid the light ones.
Step 5: Fill to the top
At 1:45, fill the brewer flush to the top or about 700g of water.
Step 6: Wait for it to brew
At 4:00, you should be pretty close to volume. Look at the glass bubble or belly button, which indicates 20 ounces. Lift the filter. It’s okay to hover for a couple of seconds to make sure you have enough volume. Then pull the filter out completely and let it drain into the sink.
Step 7: Serve and enjoy
Swirl the Chemex around a little and you’re ready to serve two cups of brewed coffee.
