Burr The burr material and design is the proud result of years of dedicated research and development at Comandante®’s onsite coffee lab. Nitro Blade® is unique, using a high-alloyed, high-nitrogen stainless steel with a fine martensitic micro-crystal matrix. Burr Geometry has been optimised to achieve excellent Bean Thruput with a reduced Crank Torque and at the same time deliver a refined Particle Size Distribution for best brewing results. Grind adjustment Comandante click system gives you full control for any brewing method and locks your preferred grind setting into place, helping you get the very best out of your roasted coffee and repeat the results again and again. This world class grind performance has made Nitro Blade the weapon of choice for true coffee enthusiasts around the globe, from home baristas to World Brewers Cup champions. Design Stainless steel is the right choice to build a robust and food safe coffee grinder. That is why not only the burr is made of stainless steel, but also the body, axle, crank and micro ball bearings. Comandante products are aluminium free. Where polymers can be used to improve performance, Comandante uses BPA-free high-performance polymers that meet the strictest food-safety standards. These materials are engineered to endure years of heavy use. Comandante loves natural wood. The solid oak handles, produced by friends in Germany’s Black Forest, are both wonderfully ergonomic and beautiful to look at thanks to oak’s unique grain structure. The Classic and Special Coating models use a robust and sleek powder coating – baked on at high temperature, not just painted on. Every C40 MK4 comes with one brown glass Bean Jar and one clear polymer-glass Bean Jar. Both are super easy to clean and hold around 40g of roasted coffee beans. Weighing in at just over 600g, the C40’s compact size and robust nature means that whether you’re at home or off on an adventure, the world’s best manual grinder is your loyal companion.
