Fiorenzato F64 EVO Commercial Espresso Grinder
The F64 EVO is the value pick in the 64 mm range, and the reason it punches above its price is the cooling fan.Most grinders in this category get warm when you push them, and that heat carries into the grounds. Your coffee starts tasting different by the middle of a rush. The EVO fan comes on automatically and keeps that from happening, which means you can ask more of this grinder than the price would suggest.The rest is solid commercial hardware. 64 mm flat M340 burrs, a 1.5 kg hopper, and a micrometric ring nut that moves in a continuous sweep so you can chase small changes when you switch to a new coffee.If you clean your burrs weekly, take a look at the F64 EVO PRO. Same machine, except the chamber comes off on two levers so you can do it between rushes instead of scheduling it.
