Ascaso equipped the I-Mini grinder with the same serious heavy-duty conical burrs found on its big brother, the i-2. The I-Mini's burrs are harder and more defined, with a tooth pattern that is incredibly precise and intricate. The resulting grind quality from Ascaso I-Mini is absolutely amazing and consistent. In addition, the Ascaso's burr set is simple to clean, making this often overlooked yet important task a breeze rather than a chore. To clean, just remove the coffee bean hopper and cover to expose the grinding chamber, which takes about 30 seconds. You can perform a thorough cleaning to remove built up coffee grounds around the lower burr and then reassemble the grinder - total time is about 2 minutes.
We really cannot stress enough how much you will love the Ascaso i-Mini's precise Micrometric Regulation System (MRS). It takes a little extra time to dial in to the sweet spot for your espresso machine and achieve that elusive "God Shot," but it is time well spent. Stepless grind adjustment works by turning the knob on the right of the unit which turns a worm gear. If you were to picture this in your mind, try to imagine a screw placed right next to large gear. Even a full turn of the knob rotates that larger gear only by a fraction of a fraction of a turn, and it still gives you every conceivable setting in between coarse to fine. In contrast, many other grinders have between 40 or 50 "clicks" from coarse to fine resulting in frustration as many are forced to choose between a little too fine or a little too coarse.
So say goodbye to overcompensating for your old grinder's deficiency by fussing with your dosing amounts or tamper pressure. The Ascaso i-Mini is a doserless grinder, which means that the grinds are discharged out a chute directly into an espresso portafilter. This is a great feature for less frequent espresso drinker or even for those who just want to have the freshest possible ground espresso every single time. The I-Mini's operation couldn't be easier: Simply place your espresso portafilter beneath the chute so that it depresses the metal switch on the face of the grinder. This activates the Ascaso's motor. When you have filled the filter holder to the desired amount, remove it and the Ascaso I-Mini will immediately shut off.
