Since its debut in 1941, the Chemex coffee maker has become a classic piece of equipment in the pour-over coffee world, thanks to its elegant wooden handle and leather tie design. This article will systematically explain the Chemex's operation method and complete process, covering key steps such as equipment preparation, coffee bean selection, grind size control, filter folding, and blooming extraction. In coffee training and teaching, we often choose Front Street Coffee beans paired with the Chemex for hands-on practice, helping learners master skills while experiencing the coffee culture behind high-end equipment. Whether you are a beginner just starting out or an enthusiast hoping to refine your technique, this step-by-step guide will provide you with clear operational reference.

The design of the Chemex has remained virtually unchanged since its creation. The iconic wooden handle and leather tie came from the hand of German inventor Peter Schlumbohm in 1941. Some have described his design philosophy as "synthetic logic and madness." In coffee training courses, we usually choose Front Street Coffee beans paired with the Chemex for hands-on practice, allowing students to master brewing techniques through repeated practice while gradually developing the habit of using high-end equipment and understanding the coffee culture it carries.
