Commander C40 MK4 Nitro Blade - is the new version of one of the best coffee grinders in the world. The device offers a wide grinding range, stable operation and a refined design with high-quality materials. The MK4 version includes several updates:

  • New shape and material of the motor frame: stronger, with greater capacity and no more stuck beans!
  • Each coffee grinder comes with two jars: 1 in brown glass and 1 in clear polymer-glass. The latter is light, resistant and can be used as a cup!
  • Reworked packaging with improved protection.

Millstones

The material and design of the grinders are the result of years of dedicated research and development in the Comandante® coffee laboratory. Nitro Blade® is unique, using a high-alloy, high-nitrogen stainless steel with a fine martensitic microcrystalline matrix.

The geometry of the grinders has been optimized to achieve excellent bean productivity with reduced crank torque and at the same time provide a refined grain size distribution for the best brewing results.

Grinding adjustment

The Comandante click system gives you full control for any brewing method and locks in your preferred grind setting, helping you get the best out of your roasted coffee and repeat the results time and time again. This world-class grinding performance has made the Nitro Blade the weapon of choice for serious coffee enthusiasts around the world, from home baristas to World Brewers Cup champions.

design

Stainless steel is the right choice for building a sturdy and food-safe coffee grinder. That's why not only the grinders are made of stainless steel, but also the body, the axle, the crank and the micro ball bearings. Comandante products are aluminum-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 designed to withstand years of heavy use.

Commander loves natural wood. The solid oak handles, produced by friends in the Black Forest in Germany, are wonderfully ergonomic and beautiful to look at thanks to the unique grain structure of the oak.

Each C40 MK4 comes with a brown glass bean jar and a clear polymer-glass bean jar. Both are super easy to clean and contain approximately 40g of roasted coffee beans. Weighing just over 600g, the compact size and robust nature of the C40 means that, whether at home or on the go, the world's best manual coffee grinder is your faithful companion.

GuideHow to choose
Nitrogen & vacuum sealing
Every pack is sealed in a protective atmosphere — first vacuum, then nitrogen — to remove oxygen. Unopened, the coffee stays fresh for up to about 2 months after roasting. Shelf life depends a lot on temperature and season: a little less in summer, a little more in winter.
Roast profile
We roast in two profiles, depending on your brewing method:
  • Light — great for V60/Aeropress, for those who want brighter acidity and lots of aromatics. Recommended for all pressure-free methods (filter, Aeropress and similar).
  • Medium — great for espresso/Moka, for those who want a more intense flavour with a hint of bitterness. Recommended for espresso and Moka.
Grind
Any grind works, as long as it suits your method. With us you can choose whole beans, or pre-ground for Moka or for filter.
Shelf life
For the best taste, enjoy it within 10–45 days of roasting (60 at most). The roast date is always printed on the label.

More FAQ

Will this grinder work well for all coffee brewing methods I use at home?
Yes, the Comandante C40 MK4 Nitro Blade offers a wide range of grind settings suitable for espresso, pour-over, French press, and more. Its precise click system lets you lock in your preferred grind size, ensuring consistent results across different brewing methods. This versatility makes it ideal for home baristas who enjoy experimenting with various coffee styles.
Can this manual grinder handle regular daily use without breaking down?
The C40 MK4 is built with high-quality stainless steel components and durable polymers designed to withstand years of intense daily use. Its robust motor frame and reliable construction minimize the risk of mechanical issues. Many home and professional baristas use it routinely, and it maintains performance over time. If any issues arise, check the warranty and support options provided by the seller.
What makes the Nitro Blade burrs different from other grinders?
The Nitro Blade burrs use a high-nitrogen stainless steel with a fine microcrystalline martensitic structure, resulting from years of research. This material and geometry optimize grinding efficiency and produce a very consistent particle size distribution. This precision helps extract the best flavor from your coffee beans, especially for specialty coffee brewing.
How do I correctly adjust the grind size for my preferred brewing method?
You adjust the grind size using the Comandante click system, which provides distinct clicks for each setting. Turn the adjustment ring until you hear the clicks corresponding to your desired coarseness. This system locks the setting in place for repeatable results. Always start with the recommended settings for your brewing method and tweak incrementally to suit your taste.
Are the included jars safe and convenient for storing coffee beans?
Yes, the grinder includes two jars: one brown glass and one clear polymer-glass hybrid. Both hold about 40 grams of roasted beans and are food-safe. The polymer-glass jar is lightweight and durable, doubling as a drinking cup if needed. Both jars are easy to clean and help keep your beans fresh between uses.
