Which component holds the coffee beans?

Which component holds the coffee beans?

• A. Dosing chamber
• B. Grinding burrs
• C. Portafilter
• D. Hopper

Answer: (D)

Beans are stored before grinding in the hopper, the container at the top of many grinders. Its job is to hold the beans and feed them down into the grinding burrs so they can be ground. The grinding burrs are the actual parts that crush the beans into particles. After grinding, a dosing chamber may collect a measured amount of ground coffee to be prepared for the shot, and the portafilter is what you place the ground coffee into for extraction in the espresso machine. So the hopper is the component that holds the beans.
