The Comandante C40 hand grinder has long been known as one of the best manual coffee grinders in the world. The MK4 Nitro Blade updates this classic in several concrete ways. Liquid Amber is a colour option in which oak details and a warm tone make the grinder exceptionally beautiful.

Comandante C40 MK4 Nitro Blade Liquid Amber hand grinder

The heart of the Comandante C40 hand grinder is the Nitro Blade burr. It is made from high-alloy, nitrogen-enriched stainless steel with a very fine-grained microcrystalline structure. The burr geometry is designed so that grinding takes only moderate torque yet still produces an even grind. In practice, an even particle size distribution means consistent extraction from one brew to the next.

The MK4 version brings a redesigned grinder body that is sturdier than before and holds more beans. Beans also no longer get stuck in it mid-grind. The grinder comes with two jars: a brown glass jar and a clear polymer glass jar that can also be used as a cup. The packaging has been redesigned too, so the grinder is better protected in transit.

Grind size is adjusted with Comandante's own click system. It locks the chosen setting in place, so repeating the same result is easy. The range covers every brewing method from espresso to pour over and immersion brewing. Especially with pour over and other filter methods, an even grind shows directly in the quality of the cup.

The body is aluminium-free and made of stainless steel. The axle, crank and ball bearings are steel too. That is why the grinder stands up to daily use for years. The plastic parts are BPA-free and meet strict food safety standards. The oak parts come from Germany's Black Forest region and are both ergonomic and beautiful.

That said, the C40 MK4 Nitro Blade is not a budget product. It is, however, an investment that pays for itself every morning. It also works just as well at home as it does as a travel companion. The grinder weighs only a little over 600 grams in total, so it is easy to take along.

So the C40 MK4 is an excellent fit for the coffee lover who will not compromise on grind quality. An occasional user, on the other hand, may find a more suitable option at a lower price. Above all, the Comandante C40 is a tool that serves every brewing method with its wide adjustment range. If you are looking for a quality hand grinder, this is a strong choice.

The grinding capacity is practical too: the jars hold about 40 grams of roasted beans, which is plenty for one or two servings.
