Overview
The Commandante C40 MK4 is the latest iteration of the legendary C40, featuring an updated burr design and refined adjustment mechanism. The MK4 burrs deliver improved particle uniformity compared to earlier versions, particularly in the filter and coarser ranges. The stepped adjustment remains precise and repeatable, with the number of clicks per setting unchanged from earlier models. Build quality remains impeccable, with the same premium materials and craftsmanship that have defined the C40 for a decade. The MK4 is an evolutionary update that refines rather than reinvents, keeping the C40 at the forefront of hand grinding excellence. The gold standard, refined.
The Commandante C40 MK4 features a 39mm conical burr set, crafted from steel. Grind retention is approximately 0.1g — virtually zero retention, making it excellent for single dosing.
At $299, the Commandante C40 MK4 is aimed at home baristas seeking a solid grinder without a premium price tag. Key workflow features include single-dose design (no hopper needed). As a hand grinder, it's completely silent, portable, and gives you a meditative morning ritual.
The Commandante C40 MK4 is weighing 0.5 kg, manufactured in Germany. Its footprint measures 53 x 53 x 200 mm (W×D×H).

Our Verdict
The Commandante C40 MK4 is a hand grinder, which means it trades speed and convenience for portability, silence, and often better value per dollar of grind quality. At this price point, you're getting a premium hand grinder that competes with electric grinders costing significantly more. If your daily routine involves 1-2 drinks and you enjoy a mindful morning ritual, this is an excellent option. For larger households or back-to-back drinks, consider an electric alternative.
