As the "legendary machine" in the specialty coffee world, the Mahlkonig EK43 has long since risen from a single-origin grinder to a standard fixture in espresso cafés, thanks to its outstanding grind uniformity and extraction performance. From early experiments at Café Myriade in Montreal in 2009 to Matt Perger's endorsement on the world competition stage in 2013, the EK43 was gradually elevated to iconic status. Meanwhile, Ditting, another "high-end grinder," is often compared with the EK43, with each having its own strengths in burr layout and flavor profile. This article reviews the grind settings and structural differences among the EK43 series versions (EK43S, EK43T, EK43, EKK43), traces its rise to fame, and compares the design features of Ditting's horizontal flat burrs. Combined with Matt Perger's particle experiment data, it analyzes why the EK43 can achieve more uniform extraction.

Many coffee enthusiasts, before brewing pour-over coffee, hear experienced baristas emphasize the step of "seasoning the grinder."

The two serve different purposes and should not be confused. This article explains in detail why a small amount of beans from the same batch should be used to season the grinder before grinding coffee beans, how residual coffee powder and burr oils affect the flavor of the next cup, and why an air blower cannot replace bean seasoning. At the same time, Front Street Coffee will also offer recommendations on the amount of beans to use for seasoning, helping you present the true flavor of each bean in a purer way. [more…]

What's the difference between cleaning a hand grinder and an electric grinder? Can the burrs be washed with water?
