Comandante C40 MK4 - Ease Of Use

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.

Grinder Build Quality

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 grinder includes a clear and a brown jar for grinding into and storing beans. With an intentionally engineered durability, the Comandante C40 is built to last.

Coffee Grind Quality

There are numerous grinders out there aimed at those looking for exceptional quality, but not all of them hit the mark. If you have been used to using the likes of Hario, Tiamo or even Porlex, then this is a massive jump up in quality. The main contributors to this come from two elements.

The first is that the grinder burr set is very high-quality steel conicals, which deliver fast and precise grind. The second is that this type of grinder is held together with a solid metal shaft through the middle of the unit that is held in 3 separate positions, which stops the burr set moving and maintains a much more consistent grind, reducing both large fragments (boulders) and powder (fines), both of which contribute to lowering the quality of your coffee.

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.

Commandante grinders come with a standard 1 year back to base warranty with Machina. *See our terms and conditions for further information
