C40 MK4 Nitro Blade Coffee Grinder & Coffee Set

Our test winner: The best among the really good ones

Its predecessor models had already set new standards. Anyone who didn't want to compromise on their hand grinder couldn't ignore the Comandante MK2. The successor model took a lot of time to completely redesign the grinder. And so it came as no surprise: the Comandante C40 MK3 Nitro Blade immediately impressed the discerning coffee scene and represents a significant improvement on the previous model! The development process was guided by an uncompromising focus on quality and grinding results. Accordingly, the design continues to emphasize clarity and perfection of form. The Comandante C40 MK4 now continues the success story.

The grinder – the heart of the Comandante

The MK4 grinder is made entirely of stainless steel, which is manufactured using a patented process. The result: an extremely durable material in knife steel quality. The edges of the grinding discs are sharpened again after hardening and literally “cut” the coffee beans. The grinder achieves an extremely precise and homogeneous grinding result with virtually no “fines” (coffee dust) across all grind sizes. The grind size can be easily adjusted using a small wheel on the underside. Power transmission during grinding is optimized thanks to the double ball bearing. Grinding coffee by hand has never felt better or easier.

Unique design

The latest version (MK4) offers a range of new, intelligent improvements, including the new bean container made of durable polymer glass.

Warmth, From the Farm to Your Cup

Hendra feels like a quiet afternoon while snow gently falls – a moment just for you. Forest honey and blackcurrant meet notes of dried fruit and cocoa. Let the gentle spice of this Indonesian Arabica wrap around you, while its lively acidity awakens your senses.

Indonesian Coffee, Reimagined

The Panta Musara region in Aceh Tengah, Indonesia, is best known for traditional wet-hulled coffees. But Hendra, the farmer behind this exceptional Arabica, and his family are changing that story. Since 2010, their curiosity, dedication, and expertise have created outstanding specialty coffees that redefine Indonesia’s coffee landscape.

Today, Hendra and his family run a small, specialized washing station equipped with pulpers, washing channels, and solar-covered drying beds. The cherries are pulped, sorted in water channels, and fermented for 12–18 hours in concrete tanks. They are then dried for 8–14 days on raised beds, depending on the weather.

Before export, the coffee passes through two density tables and two rounds of hand-sorting to ensure only the best beans make it into the bag. About 40 tons of green coffee are produced here each year – grown at 1,650 meters and known for their clarity and purity. A testament to Hendra’s precision and passion.

A Family Project Built on Vision, Community, and Quality

Hendra’s story begins with his father, Hamdan, who moved from Banda Aceh to Pegasing in 2006 to grow coffee. Hendra grew up among the plants and turned the small family farm into a hub for innovation and collaboration. Today, around 70 local farmers deliver their ripe cherries to his washing station.

Hendra pays fair prices and bonuses for exceptional picking quality, even offering extra compensation for long transport routes – encouraging careful harvesting practices.
But his impact goes beyond that: in his own coffee nursery, he cultivates heirloom varieties like Abyssinia – one of the earliest coffees brought to Indonesia. By working closely with surrounding farmers, Hendra helps preserve genetic diversity, produces excellent specialty coffees, and inspires his community to grow with him.

Tips for Preparation

For this medium roast, pour over (e.g. Hario V60) works beautifully. The AeroPress or a classic filter coffee machine will also bring out the coffee’s depth and clarity – perfect for calm, cozy moments.
