Inside the Grinder: Flat Burrs and Coffee Retention

A closer look inside the grinder featured in our September 2020 SCA Barista and Brewing Skills learning. The classroom update focused on flat burrs and coffee retention.

The original photograph shows a burr assembly with coffee residue around its metal surfaces. This close view brought the equipment itself into the lesson, alongside the work of preparing drinks.
