4. Operating Instructions (Brewing Guide)
Follow these steps for optimal coffee brewing with your Chemex coffeemaker:

Folding a Chemex filter into a cone shape.
- Prepare the Filter: Fold the Chemex Bonded Filter into a cone. Place it in the top opening of the coffeemaker with the three-layered side facing the spout.
- Rinse the Filter: Pour hot water through the filter to rinse it and preheat the coffeemaker. This also removes any paper taste. Discard the rinse water by pouring it out through the spout.
- Add Coffee Grounds: For a 6-cup Chemex, use approximately 1 tablespoon of medium-coarse ground coffee for every 5 ounces of water. Adjust to taste. Place the grounds evenly in the filter.
- Bloom: Pour a small amount of hot water (around 200°F / 93°C) over the grounds, just enough to saturate them. Let it sit for 30-45 seconds to allow the coffee to "bloom" (release gases).
- Pour: Slowly pour the remaining hot water over the grounds in a circular motion, avoiding the edges. Maintain a consistent water level and allow the coffee to drip through. The total brewing time should be around 4-5 minutes.
- Serve: Once all the water has filtered through, carefully remove and discard the filter and grounds. Serve your freshly brewed coffee.

5. Maintenance and Cleaning
- Glass Carafe: The Chemex coffeemaker is dishwasher safe. For hand washing, remove the wooden collar and leather tie. Wash the glass carafe with warm, soapy water and a soft brush. Rinse thoroughly.
- Wooden Collar and Leather Tie: The wooden collar can be wiped clean with a damp cloth. Do not immerse the wooden collar or leather tie in water. Allow them to air dry completely before reattaching.
6. Troubleshooting
- Slow Drip:
- If coffee drips too slowly, your grind might be too fine. Adjust to a coarser grind. Ensure the filter is correctly positioned with the three-layered side towards the spout to allow air to escape.
- Weak Coffee:
- Increase the amount of coffee grounds or use a finer grind. Ensure water temperature is adequate (around 200°F / 93°C).
- Bitter Coffee:
- Your water might be too hot, or the extraction time too long. Try slightly cooler water or a coarser grind. Ensure you are using Chemex Bonded Filters, which are designed to remove bitterness.
