The only grinder you’ll need for your Moccamaster Coffee Maker is the KM5 Burr Grinder in Polished Silver! Made from various materials like metal, glass, and BPA/BPS/BPF/phthalate-free plastic, the KM5 Burr Grinder sets the standard on quality craftsmanship and optimal performance. Many aspects of the KM5 Burr Grinder set it apart from standard burr grinders. For one, it features 50mm flat steel burrs to provide highly precise and uniform grinding from the 8.8oz coffee bean hopper. The top of the machine features a step-less knob that helps adjust the grind size for a variety of brewing methods and preferences. Inside its sturdy metal housing is a direct-drive motor that runs efficiently, as it can grind 60 grams of coffee within 30 seconds while operating quietly. Another delightful feature is the static-reducing dispensing spout for a cleaning grinding experience and the glass container that stores and seals away your fresh grounds ready to use, which you may empty and set in a coffee grounds canister. With ECBC certification, the KMS Burr Grinder produces grounds that may be brewed to Golden Cup Standard, meaning for every gram of coffee, you’ll only need 18 grams of water.
