FIORENZATO F4 E Nano Electronic Coffee Grinder

The F4 E Nano packs genuine flat-burr performance into a compact "Nano" footprint, using 58mm burrs suited to most 58mm-portafilter espresso machines. Dosing is electronically programmed through a touch display with three keys — one-cup, two-cup, and continuous — with the two dose keys independently programmable to your preferred grind times.

Grind size is set through a ring nut adjustment paired with continuous micrometric control, giving fine, repeatable adjustment across the range rather than fixed steps. A 0.6kg bean container is sized for regular top-ups, keeping what you're grinding fresher than a larger hopper holding beans for longer stretches.

The compact "Nano" naming reflects a genuine design choice rather than just a marketing label — Fiorenzato has built this grinder specifically for kitchens and small setups where a full-size prosumer grinder's footprint simply isn't practical, without giving up the flat-burr grind quality that larger models offer.

What the touch display controls

Who it suits

• Home baristas wanting programmable dosing in a compact footprint
• Buyers matching a grinder to a 58mm-portafilter espresso machine
• Anyone valuing fine, continuous micrometric adjustment
• Kitchens where bench space for a larger grinder is limited

Fiorenzato's Nano range exists specifically to answer a common problem: wanting genuine flat-burr grind quality without the bench footprint that usually comes with it. The F4 E Nano delivers on that brief with 58mm burrs and electronic dosing in a body that's noticeably more compact than most comparable prosumer grinders, without cutting corners on adjustment precision or build quality.

Getting the best out of it

Program your one-cup and two-cup keys once you've dialled in a grind you're happy with, and rely on the ring nut for any future adjustments rather than resetting from scratch. Since the hopper holds 0.6kg, plan on topping up with fresh beans reasonably often rather than filling it for extended stretches — this also helps ensure what's in the hopper stays reasonably fresh between refills.

Pair the F4 E Nano with fresh coffee beans, and see the wider home grinder collection to compare it against other Fiorenzato models. Its compact build and 58mm flat burrs make it a genuinely practical choice for tighter kitchen spaces.
