Grinding represents one of the most delicate and decisive steps in coffee preparation. It is the point of balance between physics and aroma, between technology and sensory perception.
Every particle size curve, every variation in temperature or cutting speed, and every profile of the cutting discs can significantly alter the final result in the cup.

Behind a good coffee, there’s always a perfect grind. And behind a perfect grind, there’s a Colombini grinder, designed with maximum precision to achieve the specific particle size and aromatic characteristics for each type of coffee — from espresso to filter to Turkish, and throughout the world of specialty coffee — by combining power, precision, and absolute repeatability, satisfying the most rigorous demands of every roaster.

From October 17 to 21, we’re bringing a wide range of coffee grinders to the new edition of Host Milano 2025, the international reference event for the world of coffee and hospitality.

Our display will include:

The MAC5: Our most powerful and high-performing model, designed for large-scale production without compromising consistency or quality.

The MAC3 (with degassing system): Optimized for the efficient production of coffee in pods, ensuring that aroma and freshness are preserved.

The TA250special: Specifically engineered for the incredibly fine grind required for authentic Turkish coffee.

The Angel: Our versatile and compact grinders, perfect for small-scale roasters and the demands of the specialty segment.

We invite you to stop by our stand to view our range of grinders, see the compact Angel in action, and discuss how our expertise can enhance the quality and efficiency of your production.

We are in Pav18, Stand F24 G23.

No, we’re not Swiss. But if there’s one thing that connects us to the Swiss, it’s our dedication and rigor in the pursuit of maximum precision. And our interest in particles – coffee particles, of course.

Our grinders are the result of years of research and development, equipped with advanced control systems and top-quality components that ensure impeccable performance and exceptional durability.

The grinding discs, the heart of our machines, are designed with meticulous precision, each one tailored to the specific requests of the client and the characteristics of the coffee. Material, geometry, cutting angles, tooth curvature, pitch, and groove depth: each of these dimensions influences the grinding result and the morphology of the resulting particles.

We constantly perform laser particle size analysis on the ground coffee to deliver the extraction curve required by the market or individual client. If necessary, we recalibrate the machine’s settings to correct the curve and eliminate unwanted variations.

But our research also focuses on continuously improving the overall operation and management of our grinders, their application flexibility, and modularity, always keeping temperature under control and maximizing production capacity and the quality of the ground product. This approach has allowed us, for example, to obtain a patent for our MAC3 and MAC5 grinders, where both burrs can rotate independently and are fully adjustable.

We also develop new customized accessories and complements like compactors, refrigerated and insulated transport systems, and degassing plants. These allow roasters and coffee producers to maintain a high and consistent standard, reducing waste and maximizing the potential of every coffee batch.

In short, we certainly don’t need particle accelerators, but in our own way, we consider coffee grinding an exact science, for its rigor, robustness of proof, and repeatability of results.

With our “Swiss precision,” you can always achieve the desired extraction curve, from espresso to filter, from capsules to brewing, guaranteeing the best sensory and organoleptic experience coffee after coffee.
