What is a burr basket?

A burr basket is a component found in many types of coffee grinders, particularly those that use burr grinders rather than blade grinders. It's essentially the housing or mounting structure that holds the burrs in place and ensures their precise alignment. The alignment of the burrs is critical for achieving a consistent and uniform grind size, which directly impacts the quality of the coffee extraction. The basket often includes features to adjust the distance between the burrs, allowing users to select the desired grind size, from coarse for French press to fine for espresso. The materials used for the burr basket can vary, ranging from plastic to metal (such as aluminum or stainless steel), with metal generally being preferred for its durability and ability to maintain precise tolerances. A well-designed and sturdy burr basket contributes significantly to the grinder's overall performance and longevity.
