Otto LEONARDO 75E Coffee Grinder

The Leonardo 75E is built for genuine throughput, with 75mm flat burrs rated to grind at more than 4.5 grams per second. Otto's "High Speed" maintenance design means burr cleaning and replacement is quick without putting your grind size calibration at risk — relevant for any grinder expected to handle this kind of daily volume. The ACE System (Anti-Clumps and Electrostaticity) lowers the electrostatic charge of ground coffee to reduce clumping and spraying during dosing.

Stepless micrometric regulation — a patented Conti Valerio design — gives infinite adjustment points rather than fixed steps, and a touch display handles counter dosing with start/stop function, direct grinding activation, and two programmable doses plus manual dose. A solid metal fork with white anodising directs grounds cleanly into the portafilter.

What the Leonardo 75E is built for

Who it suits

• Cafés and venues needing genuine high-volume grinding capacity
• Buyers wanting fast burr maintenance built into the design
• Anyone prioritising clean, low-static dosing at scale
• Operators comparing large-format grinders on throughput and daily capacity

Because burr wear scales with volume, a grinder rated for this level of daily use rewards a consistent cleaning and calibration routine rather than reactive maintenance after grind quality starts to drift.

Getting the best out of it

Given the burr size and speed, small adjustments near your target setting will have a noticeable effect on the finished grind — dial in gradually rather than making large jumps between settings. Take advantage of the quick burr maintenance design and keep to a regular cleaning schedule, particularly given the daily volume this grinder is rated for.

Pair the Leonardo 75E with fresh coffee beans, and see the wider home grinder collection to compare it against other Otto and large-format models. At this scale, consistent daily servicing matters as much as the initial dial-in.
