C40 MK4 Nitro Blade Virginia Walnut

Precision grinding wrapped in natural wood. Virginia Walnut pairs the C40 MK4’s benchmark performance with a warm, real-wood veneer—each grinder unique in grain and tone—while inside, Comandante’s Nitro Blade® burrs deliver clean, sweet, and remarkably consistent grinds from espresso-fine to coarse.

The MK4 generation refines daily use with a lighter, tougher internal frame and smarter bean path, plus two Bean Jars in the box: one brown glass (light-protective) and one clear Polymer Bean Jar that’s lightweight and basically unbreakable. Both are food-safe, easy to rinse, and each holds about 40 g of roasted coffee—perfect for pre-dosing and travel. Made in Germany.

At the heart of it all is the proprietary high-alloy, high-nitrogen stainless-steel burr set, engineered for outstanding edge retention and a tight particle distribution—one reason coffee pros rely on the C40 for precise, repeatable results across brew methods. 

German-built craft, industry-defining Nitro Blade performance, and a distinctive Virginia Walnut exterior—engineered for exacting results at home, on bar, or on the road.
