A method of preparing a coffee with the Chemex

• Prepare the filter and place it in Chemex
• Fill the kettle and bring the water to about 90 ° / 96°
• Rinse the filter with plenty of warm water to remove the hints of paper by the filter and heat the Chemex. Once this step is done to throw away the water.
• Place the Chemex zeroed on the scale and tare.
• Grind coffee. Remember to grind coffee beans immediately before you prepare the Chemex, as flavorings tend to volatilize already 30 seconds after grinding. The particle size of the ground must be medium-coarse. An excessively fine grind could block the extraction of your coffee.
• Pour the amount of ground coffee in the filter according to your preference and calibrated the scale to zero. We will use a coffee report / water 1 gram 14 ml.
• Start the timer and begin to pour the water slowly in a clockwise direction so as to saturate all the coffee. For the first infusion you have to pay an amount of double water than coffee powder. This phase is also called bloom and allows the coffee to release the gases contained in it, especially if it is a fresh coffee roasting.
• Wait 30 seconds and start to pour the water slowly and clockwise. Be in motion not to touch the edges of the filter and the ground coffee is always covered with water until you reach the desired weight. This process should last approximately 2 / 3 minutes.
• As soon emerges from the ground coffee filter, remove it and throw it away. The timer should mark the 3.30 to 4.30 minutes. If the extraction time was increased try to pour the water faster or coarser grind in a coffee. If you put less time you try to pour the water more slowly or more finely grind coffee.
• Serve the coffee extract in a cup directly from the same Chemex.
• You can clean the Chemex with any hot water left in the kettle.
