Step-by-Step Guide to Brewing Chemex Coffee
Now that you have all the necessary tools, it’s time to brew some delicious Chemex coffee. Follow these simple steps to create a perfect cup.
Step 1: Choose Your Coffee Beans
Select your favorite coffee beans. It’s generally recommended to go for lightly roasted beans since they retain more of their natural flavors. For optimal results, choose whole beans from a reputable source.
Step 2: Measure Your Coffee and Water
A common ratio for Chemex brewing is 1:16 (coffee to water). This means for every gram of coffee, you’ll need about 16 grams of water. For example, if you are brewing 30 grams of coffee, you would use approximately 480 grams of water.
Step 3: Grind the Coffee Beans
Grind your coffee beans to a medium-coarse consistency, similar to that of sea salt. Grinding too finely can result in bitter coffee, while too coarse can lead to a weak brew.
Step 4: Prepare the Chemex and Filter
Place the Chemex on the scale and weigh out your desired amount of water.
- Fold the Chemex filter along the seam and place it in the top of the Chemex.
- Rinse the filter with hot water to eliminate paper taste and preheat the Chemex. Discard the rinse water.
Step 5: Add Coffee Grounds
Add the ground coffee to the filter-lined Chemex.
Step 6: Bloom the Coffee
Start by pouring just enough hot water (about twice the weight of the coffee) over the grounds to saturate them. Allow the coffee to bloom for approximately 30-45 seconds. This process releases carbon dioxide, which helps in flavor extraction.
Step 7: Pour the Water
After blooming, slowly pour the remaining hot water over the coffee grounds in a circular motion. This should take about 3-4 minutes. Use a timer to track this process, as over-extraction can lead to bitterness.
Step 8: Allow It to Drip
Once you have poured all the water, allow the coffee to drip through the filter completely. This process should take about 4-5 minutes.
Step 9: Serve and Enjoy
Remove the filter from the Chemex, pour your freshly brewed coffee into your favorite mug, and enjoy!
