Comandante C40 MK4 Nitro Blade Manual Coffee Grinder

Free local delivery with 1-year Official Warranty will be included*

Espresso Retro Hong Kong Limited is an offical authorized reseller of Comandante Grinder in Hong Kong.

Across cultures and centuries, oak trees have been revered as symbols of strength, wisdom, and endurance. Similarly, oak wood has long been treasured by craftspeople and makers for being resilient, reliable, and beautiful — each tree grows in its own way, shaping wood with unique grain patterns and warm tones. 

To choose oak is to embrace this natural diversity and to continue a long tradition of working with a material deeply woven into human history — made to last, and made to be lived with. We have always crafted our unique crank knobs from this beautiful, local material. But its strength and hardness has made it unfeasible to use for the iconic veneers on our grinders… until now!

Comandante is proud to release a limited run of C40 Nitro Blade ‘Vintage Oak’ grinders in two categories: ‘Classic’ and ‘Royal’. All handcrafted by our team at HQ in Munich, they boast the rich, deep hue of smoked oak — the knob and veneer in a perfect pairing. The rare ‘Royal’ grinders all carry veneers handpicked by Comandante founder Bernd Braune for their particularly remarkable grain.

Nitro Blade® Burr

Landing in 2015, the Nitro Blade burr set revolutionised not just manual coffee grinders, but coffee making at home and beyond — the iconic Comandante® C40 with its nitro blade burr set became The Original Game Changer for serious coffee enthusiasts and professionals. 

Over a decade later, this is unchanged: nitro blade’s pioneering burr geometry, steel, and finishing provide a grind profile that remains the benchmark among conical burrs – the ultimate performance choice.

Often imitated, never outdone.

QTP® – our high-performance techno-polymer

Not all plastics are created equal. At Comandante®, we use advanced materials with purpose. QTP® is our high-performance techno-polymer – a robust long-chain polymer matrix reinforced with quartz nanoparticles. It looks and feels like ceramic but delivers super-composite strength. Engineered for durability and precision, it’s also food-safe and water-resistant. Discreetly cutting-edge, it’s built to perform.

Nitro Rex® – our custom steel

When I started developing coffee grinders many years ago, I had a clear vision: I didn't just want to create a coffee grinder. I wanted it to be a tool that would offer perfection in every turn, last for generations and delight every coffee lover. I quickly realized that the key to this lies at the heart of every grinder: in the steel. But not just any steel would do.

The search for the perfect material finally led me to one of our local Alpine regions, which has been renowned for its steel craftsmanship for centuries. Nitro Rex® is made in a place steeped in tradition, where the finest steel has been produced for generations. This special Alpine region, characterised by a long history and exceptional skill, has become the basis for something very special. The experienced local steelmakers have developed a special recipe that makes Nitro Rex® a masterpiece. Every step - from the artisanal cooking of the steel to the careful remelting and final refinement - is carried out with the utmost precision and care.

The combination of centuries-old craftsmanship and state-of-the-art technology makes Nitro Rex® unique. While many stainless steels are merely standardised products, Nitro Rex® carries the soul of generations. This historical foundation is complemented by a precise adaptation to the requirements of the speciality coffee world. The lightly roasted Arabica beans with their fine acids and complex flavours place the highest demands on a grinder. The surface of the steel must not only withstand the enormous abrasive loads, but also be absolutely neutral in flavour - and this is exactly what Nitro Rex® offers.

A Steel Like No Other
Nitro Rex® is more than just stainless steel - it is a masterpiece of material science and craftsmanship. With over 17% chromium and precisely balanced amounts of vanadium, molybdenum and other precious micro-alloys, this steel has been developed to offer exceptional corrosion resistance, hardness and wear resistance. Its complex remelting process ensures a fine, homogeneous matrix structure and a silver-white surface that is not only aesthetically impressive, but also makes coatings superfluous. Nitro Rex® remains as it was created: robust, durable and absolutely neutral in flavour - for a coffee that retains its full character.

Nitro Rex® forms the centrepiece of our grinders. It ensures the consistent precision and durability that is appreciated worldwide - whether for the finest espresso or coarse filter coffee. Every COMANDANTE grinder is made for people who make no compromises and share a passion for quality, craftsmanship and the perfect coffee.

A Personal Promise
Nitro Rex® is the result of years of tinkering, many tests and countless cups of coffee. As the father of COMANDANTE, the quality of the steel for our grinders is a matter close to my heart. My aim has always been to ensure the special originality of the respective coffee flavour - without compromise, without distraction, just the pure character of the bean.

When you hold a COMANDANTE grinder in your hands, you are also holding a piece of this quest for perfection. And even though I am proud of how far we have come, I know that there is always more to discover. The path to the perfect cup of coffee is a journey - and I am delighted that we can embark on it together.
