Say hello to the C40 Mk4 Nitro Blade® 'Racing Green'!
We never stop experimenting and oh boy, are we glad that this beautiful shade of green rolled into our lives. We knew immediately: we had to put it onto a C40 grinder!
This colourway is almost an old classic, except we added a little modern twist to make a rich green hue with a subtle sparkle!
This is a super robust powder coating applied directly to the stainless-steel grinder body. Like all Comandante® grinders, it is aluminium free and made with 100% food safe materials.
World class grind performance. Engineered to last generations. Made in Germany.
Grinding coffee with the Comandante C40 Nitro Blade Grinder elevates the concept of “making coffee from scratch” to a whole new level. The 100% natural oak wood knob fits perfectly in your hand; the cool, unyielding stainless steel body with its reinforced grip as you turn the handle. The accessible grind setting dial on the bottom of the burrs is within easy reach.
The high-alloyed, high-nitrogen stainless steel burrs and double axle bearings guarantee absolute particle uniformity, up to espresso or even the powder-fine Turkish grind, unlike other hand grinders. The Comandante C40 Nitro coffee grinder includes a clear and a brown jar for grinding into and storing beans. With an intentionally engineered durability, the Comandante C40 coffee grinder is built to last.
The MK4: What’s new
The MK4 is the latest updated version of Comandante’s C40 nitro-blade hand grinder. In fact, the MK4 has been designed with complete backwards compatibility, so all parts are interchangeable with the MK3 model. Fans of the MK3 will find a comforting familiarity in the design and performance while enjoying some amazing new features:
- New ‘indestructible’ polymer bean jar is lighter and more durable than the glass one (also included). The polymer jars are consistently weighted and so better to use in brewing competitions. They also boast heat insulation properties so can be used as a cup if you’re brewing coffee on the go!
- Freshly designed axel frame means there is now no chance of beans getting stuck in the engine frame
- Smaller box with improved protection and brand new manual; now completely made from sustainable materials.
All these changes make for improved workflow, weight, practicality and durability.
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.
For the Classic and Premium Wood models, Comandante craftsmen laminate a thin layer of beautiful wood onto the stainless steel body, before waxing and polishing it with meticulous dedication.
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 mean that whether you’re at home or off on an adventure, the world’s best manual grinder is your loyal companion.
