In this episode, we dive deep into the great debate: conical vs. flat burr grinders. We share our experiences with different grinders, like the Mazzer Robur S and the Mahlkönig E80 Supreme, testing their performance with the same coffee and recipe to highlight how grind size distribution, fines, and body influence espresso quality. We also explore the physics of coffee grinding, the role of overheating in flat burr grinders, and the fascinating difference between brittle and pliable coffee particles. Your mileage may vary, but we've got some new opinions on which direction might be best for our cafes...
