Mahlkoenig coffee grinders will once again be on hand for the world’s top baristas at the World Barista Championships being held in Melbourne in May. As a long-time grinder sponsor and active partner in the World Barista Championships, as well as a number of national barista competitions, Mahlkoenig’s machines will grind thousands of coffee beans during the four-day event. More than 25 high-end espresso grinders like the K30 Vario, in the new Air version, and the K30 Twin will be available to the participants in the World Barista Championships during their appearance on stage and in the preparation zones. The new K30 “Air” has been developed with special aroma protection features. Thanks to ventilation on the back of the grinder directly above the motor, circulated air cools the drive and minimizes heat transfer from the motor to the grinder housing. As a result, the temperature of ground coffee remains below 50°C even during rush hour.
