Fiorenzato F4 Nano Coffee Grinder

The F4 Nano is a versatile hybrid. While its compact footprint and 0.6 kg hopper make it excellent for home baristas who want professional-grade equipment, its robust build and efficient operation are also well-suited for low-volume commercial settings like small cafes or offices.

Unlike stepped grinders that lock you into preset notches, this system uses a ring nut to allow for infinite, tiny adjustments. This gives you total control over your grind size, letting you dial in your espresso shots with precision to match the specific roast and age of your beans.

The F4 Nano is specifically engineered for espresso. While it is technically possible to adjust the grind coarser, its burr geometry and adjustment mechanism are optimized for the fine, consistent particle size required for espresso extraction, so it is not recommended for coarser brewing methods.

Maintaining the F4 Nano is straightforward. The design allows for relatively easy access to the grinding chamber, though as with any flat burr grinder, you should perform regular cleaning to prevent old coffee oils from affecting the flavor of your fresh shots.

The F4 Nano operates on a timed dosing system. Once you have calibrated your grind setting, you can set the timer to deliver a consistent amount of coffee into your portafilter, ensuring repeatable results without needing to weigh every single dose manually.
