What is a burr coffee grinder and how does it work?
A burr coffee grinder is a type of coffee grinder that uses two abrasive surfaces, known as burrs, to crush and grind coffee beans. The burrs are typically made of stainless steel or ceramic and are designed to rotate in opposite directions, creating a grinding action that produces a consistent and precise grind. Unlike blade grinders, which chop the beans into small pieces, burr grinders crush the beans, resulting in a more even grind and a better flavor.
The grinding process involves placing the coffee beans in the grinder’s hopper, which feeds the beans into the burrs. The burrs then crush the beans, and the ground coffee is collected in a container or chute. The grind size can be adjusted by moving the burrs closer or further apart, allowing for a range of grind sizes from fine to coarse. This adjustability makes burr grinders ideal for a variety of brewing methods, from espresso to French press.
