The iconic Comandante® C40 is a robust and precise manual coffee grinder with a unique and groundbreaking grinder: Nitro Blade®. And with the new Mk4 generation, it’s even better! Thanks to smart materials, a new grinder suspension and an indestructible polymer glass bean jar, the Comandante® C40 Mk4 offers an improved workflow and is lighter on the go. Weight and better resilience, even more convenient. The technical design of the mill is the result of years of research and development in the Comandante® laboratory. A special stainless steel with a very fine martensitic crystal structure is used for the ultimate Nitro Blade® grinder, which guarantees exceptional taste neutrality and is extremely robust and retains its sharpness. The mill geometry has been optimized over the years and delivers good productivity with easy operation and the best grinding quality. The Comandante® C40 Mk4 has a fine adjustment of the grinding degree, which also allows some fine gradations within a preparation method. The click mechanism in the grinder adjuster, which clicks into place, prevents uncontrolled adjustments during grinding and guarantees repeatable settings for all brewing methods. That performance and control makes Nitro Blade® the number one choice for coffee lovers worldwide, from home baristas to world champions. The C40 MK4 comes with two bean jars. An amber lens and a clear polymer lens. Both containers are tasteless, food safe and can be easily cleaned with hot water. They each have a capacity of 40 grams of coffee. Comandante® products are aluminum-free and are made exclusively from stable, safe and food-safe materials such as stainless steel, wood, glass or high-quality polymers. High quality polymers are used in some components of the C40 MK4 to make the reel a bit lighter, dimensionally stable and very robust. They are BPA-free and extensively tested by recognized control authorities and classified as non-hazardous with food. Comandante® loves wood. The crank handle of the C40 MK4 is made in the Black Forest and consists of solid oak – a solid piece of nature with a beautiful grain that fits perfectly in the hand and works ergonomically and efficiently. For the Classic and Premium Wood versions, a thin and beautiful real wood veneer is carefully applied to the housing by hand and treated with a harmless hard wax oil. The Classic and Special Coating versions have a robust and sleek powder coating.
