From selecting the right grind size to perfecting your pour, we'll cover the essential steps and tips to help you extract the best flavors from your beans.

Why Choose the Chemex Five Cup?

The Chemex Five Cup Coffeemaker is the perfect size for individuals or small households. Its handblown glass construction not only looks stunning on your countertop but also ensures even heat distribution during brewing. The signature wooden collar and leather tie add a touch of sophistication, while the thick bonded paper filters trap oils and fine particles, resulting in a crisp, sediment-free cup.

One of the key advantages of the Chemex is its ability to brew coffee with a clean, tea-like body that highlights the subtle nuances of your beans. Unlike metal filters, the Chemex paper filter removes most of the oils, producing a lighter, less bitter brew. This makes it an excellent choice for those who prefer a delicate, aromatic cup.

• Handblown borosilicate glass is durable and resistant to thermal shock.
• The 5-cup capacity is ideal for brewing 2-3 mugs of coffee.
• Wood collar and leather tie are removable for easy cleaning.

Essential Equipment and Ingredients

To brew the perfect cup with your Chemex, you'll need a few key items. First and foremost, a high-quality burr grinder is crucial for achieving a consistent grind size. For the Chemex, you'll want a medium-coarse grind, similar to sea salt. This allows for optimal extraction without over-extracting bitterness.

You'll also need Chemex Bonded Filters, which are thicker than standard paper filters and are essential for the signature clean taste. The pre-folded squares fit perfectly into the top of the Chemex and remove any papery taste when rinsed properly. Additionally, a gooseneck kettle with a temperature control is highly recommended for precise pouring, though a standard kettle can work with practice.

Finally, use fresh, high-quality coffee beans. The Chemex is a brewer that rewards good beans, so choose a single-origin or a blend that you enjoy. Weigh your coffee and water for consistency—a scale is a worthwhile investment for any serious home barista.

• Chemex Bonded Filters (pre-folded squares)
• Gooseneck kettle with temperature control
• Digital scale for accurate measurements

The Perfect Chemex Ratio

The golden ratio for Chemex brewing is generally 1:15 to 1:17 (coffee to water). For a five-cup Chemex, which holds about 700 ml of water, this translates to approximately 42-47 grams of coffee. If you prefer a stronger cup, start at 1:15; for a lighter brew, try 1:17. Adjust to your taste preferences, but always measure precisely.

Water temperature is equally important. Aim for 195°F to 205°F (90°C to 96°C). If you don't have a temperature-controlled kettle, bring water to a boil and let it sit for 30 seconds to reach the ideal range. Using water that's too hot can scorch the coffee, while cooler water will under-extract, leaving your brew sour.

• Start with 42g of coffee for 700ml water (1:16.7 ratio).
• Adjust ratio to taste: 1:15 for stronger, 1:17 for lighter.
• Use filtered water for the best flavor.

Step-by-Step Brewing Instructions

Step 1: Place the filter. Fold the Chemex filter along the seam and place it in the top of the brewer, with the triple-fold side facing the spout. Rinse the filter with hot water to remove any paper residue and preheat the glass. Discard the rinse water.

Step 2: Add coffee. Grind your beans to a medium-coarse consistency and add them to the filter. Gently shake the Chemex to level the coffee bed.

Step 3: Bloom. Start your timer and pour just enough hot water (about twice the weight of the coffee) to saturate the grounds. Let it bloom for 30-45 seconds. This allows carbon dioxide to escape, which improves extraction.

Step 4: Main pour. Slowly pour water in a circular motion, starting from the center and moving outward, then back to center. Keep the water level below the top of the filter. Pour in stages, allowing the water to drain between pours. Aim to finish the total brew time around 3:30 to 4:00 minutes.

Step 5: Serve and enjoy. Once the water has drained, remove the filter and give the coffee a gentle swirl to mix. Pour into your favorite mug and savor the clean, aromatic flavors.

• Bloom for 30-45 seconds to degas the coffee.
• Pour in a slow, steady spiral to ensure even extraction.
• Total brew time should be 3:30 to 4:00 minutes.

Tips for Consistency and Flavor

Consistency is key to mastering the Chemex. Use a scale to measure your coffee and water every time. Keep a brewing log to note your ratios, grind sizes, and times, so you can replicate your best cups. Also, experiment with different beans and roast levels to discover your preferences.

Grind size plays a significant role. If your coffee tastes bitter, try a coarser grind; if it tastes sour, go finer. The Chemex is forgiving, but small adjustments can make a big difference. Also, ensure your water is fresh and filtered—chlorine or minerals can affect flavor.

Clean your Chemex thoroughly after each use. The handblown glass is dishwasher safe, but hand washing with a mild detergent is gentler. For stubborn stains, use a dedicated coffee cleaner or a mixture of baking soda and water. Store your Chemex with the wooden collar removed to prevent moisture buildup.

• Use a scale for consistent measurements.
• Adjust grind size based on taste.
• Clean your Chemex after every brew to avoid residue.

Pairing Your Chemex with Accessories
