Wooden Washer
The elegant wooden washer that adorns the Chemex doesn't just serve an aesthetic purpose. It allows you to safely grip the coffee maker when it's hot, preventing burns. This design also adds a traditional touch that contrasts with the modern glassware.
Available Capacities
Chemex comes in a variety of capacities, adapting to each user's needs. The most common are:
- Chemex 6-cup coffee maker, known as the 'Six Cup Classic'.

How the Chemex Method Works
The Chemex coffee brewing method is known for its simplicity and effectiveness. Below are the essential steps for enjoying a perfectly brewed cup.
1. Water Preparation
It's crucial to heat the water before beginning the filtration process. Hot water directly influences the extraction of flavors from the coffee.
Ideal Temperature
The recommended temperature ranges from 90°C to 96°C (195°F to 205°F). This range ensures optimal extraction of coffee compounds without burning the beans.
2. Using the Paper Filter
The cone-shaped paper filter is a fundamental part of the preparation process, as it prevents sediment from reaching the cup.
Correct Filter Placement
A paper filter should be placed on top of the Chemex, ensuring the thicker side of the filter faces the pour-over. This optimizes the coffee flow.
3. Add the Ground Coffee
The next step is to add ground coffee to the filter, which will influence the final flavor of the beverage.
Recommended Amount of Coffee
- It is suggested to use between 1 to 2 tablespoons of specialty ground coffee for every 180 ml of water.
Proper Grinding
The coffee grind should be medium to coarse. This allows for better water flow and a balanced extraction.
4. Coffee Blockade
This step consists of moistening the ground coffee before pouring all the water.
Waiting Time
After steeping the coffee with a little hot water, wait 30 to 45 seconds. This process releases the gases from the coffee.
5. Pouring the Water
The technique for pouring water is essential to the final result.
Circular Movements
It is important to pour the water in a circular motion, ensuring that all the grains are evenly saturated.
Pouring Time
This process should take between 3 to 4 minutes to achieve complete coffee extraction.
6. Completion of the Preparation Process
When finished, you can remove the filter and enjoy the coffee, highlighting the nuances and aromas extracted from the beans.
Advantages of the Chemex Method
Using the Chemex method for brewing coffee offers several distinctive benefits, making it a favorite choice among coffee lovers.
Quality of Taste
The Chemex is known for its ability to bring out the unique characteristics of each type of coffee. This extraction method enhances the natural flavors of the beans, resulting in a cup with a balanced and rich flavor profile.
Clean and Gentle Extraction
- The Chemex's specialized design and thick paper filter ensure that the resulting coffee is clean, minimizing the presence of unwanted sediment and oils.
- This translates into a smoother drinking experience, where bitterness is generally absent, allowing you to enjoy lighter, more nuanced notes.
Versatility in Preparation
Another significant advantage of the Chemex method is its versatility. It can be used to prepare different amounts of coffee, adapting to a variety of needs, from a single cup to several cups for sharing.
Plus, it's compatible with different types of coffee depending on their preparation and grinding methods, giving baristas and enthusiasts the freedom to experiment and customize their ideal beverage.
Comparison with Other Filtering Methods
The Chemex stands out from other brewing methods due to its unique features:
Vs. V60 Method
While the V60 method offers greater control over variables, the Chemex provides consistency and a cleaner extraction thanks to its coarser filters.
Vs. French Press
Unlike a French press , which retains oils and produces a more robust body, the Chemex filters out these oils for a cleaner, brighter cup.
Vs. AeroPress
The AeroPress combines immersion and pressure, while the Chemex relies on gravity and slow filtration, resulting in distinct flavor profiles.
