Yes. It is supplied with a 45g blow-up single dose hopper, and the Blow Up Cleaning System clears the grind chamber between doses so very little coffee is left behind. You weigh in exactly the dose you want, and switching between two different beans does not mean purging through the old one.

Very little, which is the whole point of the Zero. The Blow Up Cleaning System pushes air through the chamber as the grind finishes, so the grounds that would normally sit in the chute come out with your dose instead of the next one. Paired with single dosing, what you weigh in is close to what you get out, and you can move between two different beans without grinding through half a dose of the last one first. No grinder is genuinely zero retention, so expect a small amount to stay behind and to fall into a habit of a tap or a quick brush now and then.

55mm hardened steel flat burrs, driven directly by a 310W motor at 1,350 RPM. Grind adjustment is Eureka's patented stepless micrometric system, so you can move in very small increments rather than jumping between fixed steps.

Burrs are a wear part on every grinder. Brush the chamber out every few weeks, and use grinder cleaning tablets now and then if you want to strip the oils, and they hold their edge far longer. When they do go it happens gradually rather than all at once: the same setting starts running faster, you find yourself grinding finer and finer to hold your shot time, and the grind looks dustier than it used to. On the Firenze 75 you can set a burr maintenance alert by burr type so the grinder tells you instead of you guessing. Replacement burrs are a standard Eureka spare part - email sales@curiobox.ae and we will check availability for your model.

Yes. Eureka rate it at 1.8 to 2.5 grams per second in the espresso range and 2.5 to 3.5 grams per second in the brew range, and the stepless collar lets you travel between the two. The King Size dial makes it easy to find your way back to a setting you liked.

They sit on the same 55mm flat burr platform, so grind quality is close. The difference is how you feed them. The Zero is built around single dosing: it comes with a 45 g blow-up hopper and clears the chamber after every dose, which suits anyone weighing beans per shot or keeping several bags open at once. The Specialita is the more conventional setup, designed to run with a full bean hopper, for people who keep one bean loaded and want to press and go. Buy one bag at a time and drink through it, and the Specialita is the easier life. Have three bags open, and the Zero is the one.

Start with how much coffee goes through it. One or two coffees a day at home and a Mignon is the right size - the Zero 55S if you weigh single doses or keep several bags open, a hoppered Mignon if you run one bean and want speed. Serving a cafe, a restaurant or an office floor, you want the bigger burrs and the dosing control of the Firenze 75: 75mm burrs, three programmable doses and a 2kg hopper so you are not refilling in the middle of a rush. If you are somewhere between the two, tell us your daily cup count and we will tell you honestly which side of the line you fall on.

Eureka fit this model with their Silent Technology, which is aimed precisely at the noise a grinder makes early in the morning in a flat. It also carries the ACE system, which cuts clumping and static in the grounds so less coffee sticks to the chute and the dosing cup.

Black and White. Both are the same grinder mechanically, so it comes down to which one suits your counter. Whichever you choose, the body measures 120 x 215 x 363 mm and weighs 5.6 kg, so it takes up very little worktop.
