Product Info
Comandante founder Bernd Braune loves the rich hue of our C40 Nitro Blade “Deep Purple” — so much that he thought: Let’s take it even further!
With a custom-made purple oak knob and a matching purple polymer bean jar, this edition shines in the unmistakable BB style.
Handcrafted in Munich to our highest standards, the Comandante® C40 Nitro Blade “Deep Purple – BB Style” is even deeper, even bolder — as purple as purple gets.
The iconic Comandante® C40 is a robust and precise hand coffee grinder featuring a unique and groundbreaking burr set: Nitro Blade®. And with the new Mk4 generation, it has become even better!
Thanks to smart materials, a new burr suspension, and an unbreakable polymer-glass bean jar, the Comandante® C40 Mk4 offers improved workflow and, with its lighter weight and greater durability, is even more suitable for travel.
The C40 MK4 comes with two “Bean Jar” containers — one made of clear glass and one of purple polymer-glass. Both containers are taste-neutral, food-safe, and easy to clean with hot water. Each holds up to 40 grams of coffee.
Made in Germany.

About Comandante
The best coffees in the world are produced with passion. From the small coffee tree to the harvest to the processing and roasting, everyone makes sure that you end up with the best result possible.
With the C40 Nitro Blade®, Comandante has developed a grinder that can get the best out of the coffees. With the Comandante, it is up to you to set the grinder perfectly for your coffees. From espresso to filter coffee to french press, everything is possible. The X25 Trailmaster® is also equipped with this burr set.
The C60 Baracuda® contains a burr set that is a lot bigger compared to the Nitro Blade® in the C40 grinders. Due to this, it grinds significantly faster. The burr set itself is made from the same tried and tested steel as the Nitro Blade® burr sets.

Comandante Workflow
Place your Bean Jar on the Scale and dose your desired amount of Coffee.
Adjust the grind setting on the Comandante – to find the zero-point, turn the dial finer until the crank cant move freely any longer; from there, you can count the Clicks going coarser. This table is meant to be a loose guide, every coffee has its quirks:

Put the coffee into the grinder and grind ahead. When there is no more resistance while cranking, you'll have finished. Brew your coffee and enjoy!

About Nitro Blade®
The technical design of the burr set is the result of many years of research and development in the Comandante® laboratory. For the ultimate burr set, Nitro Blade®, a special high-alloy martensitic stainless steel with an extremely fine crystalline structure is used, ensuring exceptional flavor neutrality while being extremely robust and durable.
The burr geometry has been continuously refined over the years, achieving excellent productivity with easy handling and outstanding grind quality.
The Comandante® C40 Mk4 features a finely stepped grind adjustment, allowing for precise fine-tuning even within a single brewing method. The solid, click-in grind adjustment mechanism prevents accidental changes while grinding and ensures repeatable settings for all brewing methods. This level of performance and handling makes Nitro Blade® the first choice for coffee enthusiasts worldwide — from home baristas to world champions.
Comandante® products are aluminum-free and made exclusively from stable, safe, and food-grade materials such as stainless steel, wood, glass, and high-quality polymers.
High-performance polymers are used in some components of the C40 MK4 to make the grinder lighter, dimensionally stable, and highly durable. They are BPA-free and have been extensively tested and certified by recognized authorities as safe for use with food.
Comandante® loves wood. The crank knob of the C40 MK4 is crafted in the Black Forest from solid oak — a sturdy piece of nature with a beautiful grain that feels perfect in the hand and offers ergonomic, efficient operation.
