What Do You Need for Chemex Coffee Brewing?
Before diving into how to use a Chemex coffee maker, gather these essentials:
● A Chemex brewer (available in 6-cup or 8-cup sizes to suit your needs)
● Chemex coffee filters are thicker than standard filters, resulting in a cleaner brew.
● Freshly roasted coffee beans — preferably the best coffee for Chemex, such as light or medium roasts.
● A gooseneck kettle for accurate pouring.
● A scale for precise Chemex ratio measurements
● A burr grinder is preferred for consistency.
● Hot water (around 195–205°F or 90–96°C), just off the boiling point.
● A timer.
● A mug or carafe to catch your tasty Chemex coffee
How to Choose the Best Coffee for a Chemex?
The finest coffee for Chemex is crucial for an exceptional cup. Opt for high-quality, whole-bean coffee—light or medium roasts are ideal for highlighting Chemex's capacity to showcase bright, fruity, and floral notes.
Single-origin beans from regions such as Ethiopia and Colombia are excellent choices for Chemex brewing. When possible, grind your coffee beans to a medium-coarse consistency—similar to sea salt—to ensure optimal extraction and clarity in every cup during the Chemex pour-over.
Understanding the Chemex Ratio
The Chemex coffee ratio is the cornerstone of a great brew. A common starting point is the Chemex ratio of 1:16, which involves using 1 gram of coffee for every 16 grams of water. This ratio is crucial as it determines the strength and flavor profile of your coffee. It's a balance that, when achieved, results in a perfect cup of Chemex coffee.
For a 6-cup Chemex, a solid recipe includes 640 grams of water (about 22 ounces) and 40 grams of coffee.
Adjust according to your taste. Do you want a lighter brew? Add less coffee. Are you in the mood for a stronger cup of Chemex coffee? Add more coffee according to your taste. Use a scale to achieve this ratio—precision is crucial for consistent Chemex brewing.
Step-by-Step Chemex Brewing Instructions
Step 1: Prepare Your Equipment.
Start your Chemex brew guide by preparing your setup. Unfold the Chemex coffee filters, making sure the thicker, three-layered side faces the spout. Nobody likes their coffee tasting like paper, so before preheating the Chemex, rinse the filter with hot water to remove any paper taste.
Step 2: Grind your coffee.
Grind 40 grams of high-quality coffee for Chemex to a medium-coarse consistency. If it's too fine, your brew will be bitter and slow; if it's too coarse, it will be weak. This is a key aspect of brewing Chemex coffee correctly.
Step 3: Heat your water.
Heat water to 195–205°F (90–96°C). A gooseneck kettle is ideal for the precise pour needed in Chemex pour-over instructions. If you don’t have a thermometer, do not worry at all. Boil the water and let it sit for 30 seconds.
Step 4: Add coffee and allow it to bloom.
Place the ground coffee into the rinsed filter. Start your timer and pour just enough hot water (approximately 80 grams) to saturate the grounds evenly. Allow it to bloom for 30 to 45 seconds—this step, when using a Chemex coffee maker, helps release gases and enhance flavor.
Step 5: Pour Gradually.
Now, the art of Chemex pour-over begins! Slowly pour water in a circular motion, starting from the center and spiraling outward while avoiding the edges of the filter.
Add 200 grams of water every 30 to 45 seconds, pausing to allow it to drain. Continue until you reach a total of 640 grams.
The complete Chemex brewing process should last between 3.5 and 4.5 minutes for the optimal Chemex recipe.
Step 6: Remove the filter and serve.
Once the dripping has stopped, remove the Chemex coffee filters and discard them. Gently swirl the Chemex to mix the brew, then pour the coffee into a mug.
Savor the clean, bright taste!

Suggestions for the Ultimate Chemex Recipe
● Water Quality: Use filtered water for a superior taste in Chemex coffee brewing.
● Timing: If the brew takes too long (over 5 minutes), adjust your grind to a coarser setting. If it’s too quick (under 3 minutes), grind finer.
● Temperature: Keep the temperature between 195°F and 205°F for optimal extraction when using a Chemex coffee maker.
● Experiment with the Chemex coffee ratio to fine-tune your brew. For a bolder cup, try a ratio of 1:15. If you prefer a lighter brew, adjust the ratio to 1:17. The Chemex's versatility allows you to customize your coffee to your exact taste preferences.
● Cleanliness: Rinse your Chemex after every use to preserve the purity of flavors for your following Chemex recipe.
Why Does Chemex Stand Out?
The Chemex coffee brewing method stands out due to its unique features. The thick filters and pour-over design effectively eliminate oils and sediment, resulting in a crisp, clean cup. What sets it apart is the level of control it offers. With Chemex, you can control every variable—water speed, grind size, and Chemex ratio—giving you the power to create your perfect cup of coffee.
Learning to use a Chemex offers a hands-on, rewarding experience that drip machines cannot provide.
Common Mistakes in Chemex Brewing
Avoid these pitfalls for better brewing with a Chemex:
● Wrong Grind Size: If the grind is too fine, it clogs the filter, resulting in a bitter, slow brew. If it's too coarse, water rushes through, leading to weak coffee.
● Skipping the rinse: Failing to rinse Chemex coffee filters results in a papery taste that can ruin your Chemex recipe.
● Incorrect Water Temperature: Water that's too hot (above 205°F) burns the grounds, while water that's too cool (below 195°F) under-extracts, according to the Chemex brew guide.
● Uneven Pouring: Pouring water too quickly or concentrating it in one area can result in uneven extraction during the Chemex pour-over process.
● Ignoring the ratio: Guessing instead of measuring the Chemex coffee ratio affects flavor consistency.
● Not Timing: Brewing for too long or too short impacts the taste—stick to 3.5–4.5 minutes for brewing with a Chemex.
Conclusion
Mastering the use of a Chemex transforms your daily brew into a work of art. With the proper coffee for Chemex, a reliable Chemex recipe, and an understanding of common mistakes, you’ll enjoy the best cup yet.
