Beyond the Marketing: The Seasoning Debate Most home baristas view a brand-new coffee grinder as a precision instrument ready for peak performance out of the box. This assumption is a mistake. Seasoning—the process of running several kilograms of coffee through new burrs—remains a polarizing topic. While skeptics dismiss it as a waste of beans, the physical reality of metallurgy and particle distribution tells a different story. New burrs are often too sharp, causing aggressive fractures that produce excessive fines. Quantifying the Shift in Particle Distribution Data from Dr. Mark Al-Shemmeri provides a clear picture of what happens during the first 20kg of a grinder's life. Testing the Mahlkönig EK43, Al-Shemmeri observed a drastic reduction in fines and a shift in the median particle peak toward a coarser profile at the same setting. The burrs don't just 'get oily'; they physically dull from an unstable sharpness to a consistent, long-term edge. Without this stabilization, users face constant 'setting drift' where they must adjust their grind daily as the burrs naturally wear in. Burrs and Variability Geometry dictates the necessity of seasoning. Large flat burrs, like those in the DF83, show significantly more volatility than small conical burrs. Jonathan Gagne previously noted similar effects on high-end equipment like the Monolith EG-1. If you ignore this phase, you are effectively reviewing or using a prototype of your grinder’s actual performance. Strategic Seasoning for the Home User Don't burn out your motor in a single afternoon. Use cheap, dark-roasted beans—which are less dense and easier to crush—to season the burrs. Maintain the duty cycle to prevent overheating and ensure proper ventilation. Proper seasoning turns a volatile tool into a consistent companion, ensuring your espresso shots don't change recipes every morning.
