Our Verdict
The Fiorenzato F83E uses flat burrs, which are the preferred geometry for espresso among competition baristas and specialty coffee professionals. Flat burrs produce a more unimodal (uniform) particle distribution, which translates to cleaner, sweeter espresso with more clarity than conical alternatives. This is an end-game grinder for dedicated enthusiasts. The price is substantial but reflects the engineering required for top-tier particle uniformity. Pair it with a machine that does justice to the grind quality, and you'll taste the difference in every shot.
Frequently Asked Questions
Can the Fiorenzato F83E grind fine enough for espresso?
Yes, the Fiorenzato F83E is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
Why choose flat burrs in the Fiorenzato F83E?
Flat burrs produce a more uniform (unimodal) particle distribution compared to conical burrs. This translates to cleaner, more transparent espresso flavors with pronounced sweetness and clarity. Many competition baristas and specialty roasters prefer flat burr grinders for this reason.
How do I maintain the Fiorenzato F83E?
Clean out retained grounds after each use with a brush or bellows. Deep clean the burrs every 2-4 weeks by removing them and brushing away oil buildup. For the motor, occasional use of grinder cleaning tablets (like Grindz) helps remove coffee oil buildup. Never wash burrs with water.
Is the Fiorenzato F83E worth $1,800?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Fiorenzato F83E will have a bigger impact on your espresso than upgrading any other piece of equipment. If you're serious about espresso, this level of grinder investment is justified.
