Brewing with a Chemex is both an art and a science, combining precision with simplicity. Whether you’re new to the Chemex or looking to refine your technique, this guide will provide essential coffee brewing tips to help you brew the perfect cup every time.

What You’ll Need

Before you begin, gather these essentials:

• Chemex coffeemaker
• Chemex paper filters
• Freshly roasted coffee beans
• Grinder (preferably burr grinder)
• Gooseneck kettle
• Digital scale
• Timer
• Filtered water

Step-by-Step Guide: How to Use Chemex

1. Measure and Grind Your Coffee

Start by weighing your coffee beans. A general coffee-to-water ratio guideline is 1:15 or 1:16. For example, use 30 grams of coffee for 450 grams (15 ounces) of water. Adjust based on your taste preferences.

Grind your coffee to a medium-coarse consistency, similar to sea salt. Too fine, and the coffee may over-extract; too coarse, and it could under-extract.

2. Heat the Water

Heat filtered water to about 200°F (93°C). If you don’t have a thermometer, bring the water to a boil and let it sit for 30 seconds. Using filtered water ensures the best flavor for your coffee.

3. Prepare the Chemex

Place a Chemex paper filter in the Chemex coffeemaker, ensuring the triple-fold side faces the spout. This creates a proper seal and allows air to escape during brewing.

Rinse the filter thoroughly with hot water. This step removes any papery taste and preheats the Chemex. Discard the rinse water.

4. Add Coffee Grounds

Place your Chemex coffeemaker on a digital scale and tare it to zero. Add the ground coffee into the filter, ensuring the coffee bed is level.

5. Bloom the Coffee

Start your timer and pour enough hot water (about twice the weight of the coffee) to saturate the grounds evenly. For 30 grams of coffee, use about 60 grams of water. Let it bloom for 30 to 45 seconds. This step allows CO2 to escape, improving extraction.

6. Begin the Pour-Over

After the bloom, slowly pour the remaining water in a circular motion, starting from the center and moving outward. Avoid pouring directly onto the filter. Aim to maintain a steady, consistent pour rate.

Pour in stages if needed, allowing the water level to drop slightly before adding more. The total brewing time should be around 4 to 5 minutes.

7. Remove the Filter

Once the brewing is complete, carefully remove the filter and discard it. Swirl the Chemex to mix the coffee evenly.

8. Serve and Enjoy

Pour the coffee into your favorite mug and savor the clean, bright flavors that the Chemex coffeemaker is known for. Pair it with your favorite pastry or enjoy it on its own.

Tips for the Perfect Chemex Brew

• Use Fresh Coffee: Always use freshly roasted coffee beans and grind them just before brewing for maximum flavor.
• Invest in Quality Water: Since coffee is 98% water, the quality of your water has a significant impact on the final taste. Use filtered or spring water for the best results.
• Experiment with Ratios: Adjust your coffee-to-water ratio and grind size to suit your taste preferences.
• Be Consistent: Use a scale and timer to maintain consistency with each brew.
• Preheat Your Chemex: This helps maintain the coffee’s temperature during brewing.

Brewing coffee with a Chemex coffeemaker is a rewarding experience that combines aesthetics with exceptional taste.
