Precision grinding in an understated, go-with-everything finish. The C40 MK4 pairs Comandante’s legendary Nitro Blade® burr set with a lighter, tougher MK4 chassis for beautifully consistent grinds—from espresso-fine to coarse filter—while keeping crank torque low and workflow smooth. The high-alloy, high-nitrogen stainless-steel burrs deliver superb edge retention and a clean, sweet cup profile that made the C40 a benchmark for coffee pros worldwide. MK4 refinements include a strengthened internal frame and smarter bean path, plus two Bean Jars in the box: one brown glass (light-protective) and one clear polymer that’s lightweight, durable, and can even double as a cup—ideal for dosing, traveling, or quick service on bar. German-built craft, a timeless black exterior, and Comandante’s industry-defining Nitro Blade performance—designed for precise, repeatable results at home, on bar, or on the road.
