Single dosing on the Fiorenzato F4 and AllGround

The F4 series and the AllGround are Fiorenzato’s smaller-format grinders, sitting below the F64 in the range. The AllGround is built to cover more than espresso, which is where its name comes from — one grinder expected to move between brew methods.

That flexibility is exactly what makes the stock bean hopper inconvenient. A grinder used for espresso in the morning and filter in the afternoon is a grinder whose beans get changed often, and a hopper has to be emptied every time.

One dose at a time

This hopper replaces the standard bean hopper so each dose is weighed in individually. Grind, then press the silicone bellows to push grounds through the burr chamber and out. When you are alternating between a light filter roast and a dark espresso blend, clearing the chamber between them is the difference between tasting the coffee you just ground and tasting some of the last one.

We have not published burr dimensions for these models here because we could not verify a figure we would stand behind. Check your own machine’s documentation if the exact burr size matters to your decision.

Version 3

Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.

Fitting

This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
