Comandante C40 Nitro Blade Coffee Grinder MK4 (Alpine Lagoon)

The Comandante C40 MK4 Nitro Blade in Alpine Lagoon is a homage to the stunning turquoise waters found in the Bavarian Alps. This striking finish captures the serenity and sparkle of those remote mountain lagoons, bringing a touch of alpine beauty to your daily coffee ritual. Beneath the eye-catching powder-coated exterior lies the same world-class grinding performance that has made the C40 the benchmark for manual coffee grinders, trusted by home baristas and World Brewers Cup champions alike.

At the heart of the C40 MK4 sits the legendary Nitro Blade burr set, the world's first heptagonal conical burr developed specifically for specialty coffee. Crafted from high-alloyed, high-nitrogen stainless steel with a fine martensitic micro-crystal matrix, these burrs deliver exceptional particle uniformity across the full range of grind settings. The individually sharpened cutting edges slice through beans rather than crushing them, resulting in minimal fines and a clean, consistent grind whether you're pulling espresso or brewing a French press.

The MK4 generation brings thoughtful refinements to an already exceptional grinder. The redesigned engine frame eliminates trapped beans entirely, whilst the inclusion of both a brown glass jar and an unbreakable polymer jar offers versatility for home use and travel. Weighing just over 600g and built entirely from aluminium-free, food-safe materials, the C40 MK4 is engineered to deliver decades of reliable performance. The solid European oak knob, handcrafted in Germany's Black Forest, provides both ergonomic comfort and a beautiful natural contrast to the Alpine Lagoon finish.

What is the Nitro Blade burr set?

The Nitro Blade is Comandante's pioneering burr design, developed specifically for specialty coffee. It uses a unique heptagonal (seven-sided) geometry with individually sharpened cutting edges that slice through coffee beans rather than crushing them. This results in exceptional particle uniformity and minimal fines across all grind settings.

What brewing methods can I use with the C40 MK4?

The C40 MK4 offers a wide grind range suitable for virtually any brewing method. As a guide: Turkish coffee requires 5-8 clicks, espresso 8-12 clicks, moka pot 13-15 clicks, filter/pour-over/AeroPress 20-28 clicks, French press 32-35 clicks, and cold brew around 34 clicks.

What's new in the MK4 compared to the MK3?

The MK4 features a redesigned engine frame that's more robust with larger capacity and eliminates trapped beans entirely. It also includes a new unbreakable polymer bean jar alongside the traditional glass jar, and comes in sustainable packaging. All parts remain backwards compatible with the MK3.

How do I adjust the grind setting?

The grind setting dial is located at the bottom of the burrs and is easily accessible. The stepped click system locks your preferred setting into place, preventing accidental adjustments during grinding and allowing you to replicate the exact same setting time after time.

What is the Alpine Lagoon finish?

Alpine Lagoon is a turquoise powder-coated finish inspired by the beautiful colours of the Bavarian Alps. The coating is baked on at high temperature (not simply painted), making it super robust and durable. It's aluminium-free and 100% food safe.

How do I clean the Comandante C40?

Never submerge the grinder in water or put it in the dishwasher. For the exterior, simply use a damp cloth. Every two weeks, disassemble the grinder and use a brush to remove any leftover coffee grounds. Keep all parts safe during cleaning, especially the small washers. The bean jars are dishwasher safe.

Is the C40 MK4 suitable for travel?

Absolutely. Weighing just over 600g with a compact footprint, the C40 MK4 is designed for portability. The included polymer bean jar is virtually unbreakable and can even double as a drinking cup when brewing on the go.

What materials are used in the C40 MK4?

The grinder uses high-nitrogen martensitic stainless steel for the burrs, body, axle, crank and micro ball bearings. The engine frame is Eastman Tritan copolyester (BPA-free), and the knob is solid European oak with a natural wax-oil finish suitable for children's toys. All materials are food-safe, and Comandante products are entirely aluminium-free.

Where is the Comandante C40 manufactured?

The C40 MK4 is 100% Made in Germany. Comandante is a family-run company based just outside Munich, Bavaria, and all grinders are manufactured and assembled by their team of craftsmen and women using locally sourced, food-safe materials.

How long will the Nitro Blade burrs last?

The high-nitrogen stainless steel burrs are exceptionally hard (approximately 58 Rockwell hardness) with excellent edge retention. With proper care, the burrs are engineered to deliver consistent performance for many years of regular use.
