C40 MK4 Nitro Blade Racing Green
C40 MK4 Nitro Blade Racing Green
Precision grinding in a classic motorsport hue. Racing Green wraps the C40 MK4’s benchmark performance in a deep, confident finish—while inside, Comandante’s Nitro Blade® burr set delivers exceptionally clean, sweet, and consistent grinds from espresso-fine to coarse. The MK4 chassis refines the experience with a lighter, tougher build and smooth, low-torque cranking for daily use at home, on bar, or on the road.
Every MK4 includes two Bean Jars to match your routine: one brown glass (light-protective) and one clear, virtually unbreakable polymer—both food-safe and easy to rinse. Dose directly into the jar, grind with low retention, cap, and go; each jar typically holds around ~40 g of roasted coffee (varies by density).
German-built craft, industry-defining Nitro Blade burrs, and an iconic Racing Green exterior—engineered for precise, repeatable results across every brew method.
