When we first met the Nuova Simonelli MDX a few years ago, it seemed to fall into the same class as other similarly sized commercial-grade grinders did: It ground coffee quickly, uniformly and easily, so that you could extract a shot of espresso in under a minute from start to finish. But as we got to know it a bit better, we found that some its unique features made it a particularly learned choice for coffee connoisseurs and crafters alike.
First, unlike other grinders that keep the bottom burr stationary and move the top burr up and down during calibration, the Nuova Simonelli MDX does the opposite. The top burr remains stationary while the bottom adjusts up and down during calibration. This means that when you remove the top burr during cleaning, you don’t lose your grind setting and post-cleaning dial-in is a snap.
Next, the adjustment mechanism on the MDX is pretty tight: A smooth moving knob on top of the grinder versus a sometimes-jerky adjustment collar. It’s super simple to dial in the grind using the knob, leaving very little guesswork around where your grind setting is.
Other than that, though, it’s a fairly standard mid-sized commercial grinder — removable bean hopper, stainless steel flat burrs with a ~1100lb. bean lifetime, front doser chamber to capture ground coffee on the fly. In Brandon’s crew review video, he goes over all the Nuova Simonelli MDX’s features and specs, then demonstrates its grind consistency and performance.
