The Chemex coffee brewer is renowned for its ability to produce a clean, balanced cup of coffee with a smooth finish. This method, however, requires precise control over water temperature and grind size to achieve the best results. Today, we'll explore the Chemex brewing recipe that ensures a rich, aromatic cup every time.
Overview & Background
Invented by Peter Schlter in 1941, the Chemex is a pour-over coffee brewer that relies on gravity to filter coffee grounds through a paper filter. This brewing method is known for its simplicity and the ability to produce a clean, pure cup of coffee. The Chemex is particularly valued for its ability to highlight the unique characteristics of the coffee beans used.
Key Brewing Parameters / Specs
- Water Temperature: 96°C (205°F)
- Grind Size: Coarse
- Coffee to Water Ratio: 1:16 (e.g., 25g of coffee for 400ml of water)
- Brew Time: 4-5 minutes
Step-by-Step Guide
- Prepare the Chemex: Rinse the Chemex with hot water to remove any paper taste and preheat the carafe. Discard the water.
- Place the Filter: Fold a single layer of Chemex filter into a cone shape and place it into the Chemex. Ensure it fits snugly without being too tight.
- Weigh the Coffee: Measure out the appropriate amount of coffee based on your desired strength and pour it into the filter. Use a coarse grind size.
- First Pour: Pour a small amount of water (about 50ml) over the coffee grounds to dampen them. Let this sit for 30 seconds to allow the grounds to bloom and release gases.
- Slow Pour: Start pouring the remaining water (about 350ml) in a steady, slow stream, allowing it to fully pass through the coffee grounds. The water should flow through the grounds at a rate of about 1 ml per second.
- Final Pour: Once all the water has been poured, let the coffee continue to drip through the filter for an additional 30 seconds. The total brewing time should be around 4-5 minutes.
Pro Tips & Common Mistakes
- Use Fresh Water: Always use fresh, clean water to avoid any off-flavors.
- Consistent Grind Size: A consistent coarse grind size is crucial for even extraction.
- Controlled Pouring Speed: A steady, slow pour ensures even extraction of flavors.
- Avoid Over-Brewing: Over-brewing can result in a bitter taste. Ensure the coffee drips through the grounds within the 4-5 minute range.
