Fiorenzato F4: The Italian Workhorse That Flies Under the Radar
The Fiorenzato F4 is a commercial espresso grinder that doesn't get nearly enough attention. While baristas argue about Mahlkonig, Mazzer, and Mythos, this Italian-made grinder quietly powers thousands of cafes across Europe and Australia. It's built tough, grinds well, and costs less than most of its competition. I've used one for over a year in a mid-volume cafe, and I think it deserves a closer look.
I'll walk you through the F4's key features, grind quality, how it handles in a real cafe environment, and where it fits against better-known competitors. If you're shopping for a commercial grinder or just curious about Fiorenzato as a brand, this should cover everything you need.
Fiorenzato as a Brand: Quick Background
Fiorenzato is a family-owned Italian company based near Venice that's been making coffee grinders since 1936. They're not as flashy as some competitors, and they don't spend much on marketing outside of Europe. But they have a loyal following among cafe owners who value reliability over brand prestige.
The F4 sits in the middle of their commercial lineup. Below it, you've got the F5 (a compact on-demand grinder). Above it, the F64 and F83 models target higher-volume shops and specialty coffee bars. The F4 is designed for cafes pulling 100-250 shots per day, which covers most independent coffee shops.
What I like about Fiorenzato's approach is that they don't try to pack in every feature imaginable. The F4 does the basics extremely well: consistent flat burr grinding, reliable timed dosing, and a build quality that holds up to daily abuse.
Grind Quality and Burr System
The F4 uses 64mm flat steel burrs, which is the same size you'll find on many competitors in this price range. The burrs spin at around 1,350 RPM, which is on the slower side for a commercial grinder. Slower RPM generally means less heat transfer to the coffee, which helps preserve volatile aromatics.
Particle Size Distribution
I ran the F4 against a Mahlkonig E65S for a week, pulling identical shots on the same espresso machine. The F4 produced a slightly wider particle distribution, meaning a bit more variance between the largest and smallest particles in each dose. In the cup, this showed up as slightly less clarity on light roasts but actually a bit more body and sweetness on medium roasts.
For most cafes running medium to dark roast espresso blends, the F4's grind quality is excellent. If you're running a single-origin light roast program where you need laser-sharp clarity, you might want to step up to a grinder with larger burrs or a more uniform distribution.
Stepless Adjustment
The grind adjustment is stepless (infinitely adjustable), which means you can fine-tune to exactly where you need to be. The adjustment collar has a nice resistance to it, so it won't drift during service. I found the dial responsive enough that a quarter-turn made a noticeable difference in shot time, which is about right for dialing in.
Build Quality and Design
The F4 weighs about 14 kg (31 lbs), making it lighter than many commercial grinders in its class. The body is mostly aluminum with a polycarbonate hopper that holds about 1.2 kg of beans. Build quality is solid. After a year of daily use, my unit shows some cosmetic wear on the portafilter fork but zero mechanical issues.
The doser-less design feeds grounds directly into the portafilter through a chute. There's no clump crusher, which is one area where the F4 lags behind pricier options. I found that a quick tap on the portafilter and a brief stir with a distribution tool was enough to break up any clumps before tamping.
Noise Level
This grinder is not quiet. At about 72-75 decibels during operation, it sits in the same range as most commercial grinders. If noise is a priority for your cafe, the newer Mythos 2 or Mahlkonig E80 are significantly quieter. But for most shop environments with background music and conversation, the F4's noise level isn't a problem.
Workflow and Daily Performance
The F4 uses timed dosing with two programmable buttons (single and double). You set the grind time for each button, and the grinder stops automatically. Timed dosing is less precise than gravimetric (weight-based) dosing, since bean density varies between roasts. I found my doses varied by about 0.3-0.5 grams, which meant I still needed to weigh every third or fourth dose to make sure I was on target.
For a cafe running a single house blend, this level of accuracy is fine. If you're switching between two or three different coffees throughout the day, you'll need to adjust both the grind size and the timer each time, which adds a bit of friction to your workflow.
Retention
Retention is about 1.5-2 grams in the grinding chamber. That's better than the Mythos One but worse than the best low-retention designs. For single-dosing at home, this would be annoying. For a busy cafe where the grinder runs almost continuously, the retained grounds get pushed through quickly and it's not an issue.
Pricing and Value Comparison
The Fiorenzato F4 typically sells for $1,200-1,600, depending on the market. That puts it well below the Mythos One ($2,500-3,500) and the Mahlkonig E65S ($2,000-2,500), while delivering grind quality that's surprisingly close to both.
Here's how I'd summarize the value proposition:
- F4 vs. Mythos One: You lose temperature stability, gravimetric dosing, and the iconic build. But you save $1,000+ and get 85-90% of the grind quality.
- F4 vs. Mahlkonig E65S: Very similar grind quality. The E65S has better electronics and a slightly more refined workflow. The F4 costs about $600-800 less.
- F4 vs. Mazzer Super Jolly: The F4 is a clear upgrade in every way. Better grind quality, better workflow, similar price.

Who Is the F4 Best For?
Ideal for:
- Independent cafes pulling 100-250 shots per day
- Owners who want commercial quality without a premium price tag
- Shops running medium to dark roast espresso blends
- Second grinder for decaf or a guest espresso
Less ideal for:
- High-volume shops pushing 400+ shots daily (step up to the F83 or a Mythos)
- Light roast specialty programs that demand maximum clarity
- Anyone who needs gravimetric dosing built in
- Home users (still too large and too much retention for single-dosing)

Maintenance Tips
The F4 is easy to maintain. Weekly, run grinder cleaning tablets through it (Urnex Grindz or similar). Monthly, remove the top burr carrier and brush out accumulated coffee oils and fines with a stiff brush. The burrs will last about 600-900 kg of throughput before needing replacement, and replacements run about $80-120.
One specific tip: the portafilter fork is adjustable for different portafilter sizes, but the adjustment mechanism can loosen over time. Check it every few weeks and snug it up if your portafilter starts sitting at an angle.
Frequently Asked Questions
Where can I buy a Fiorenzato F4 in the US?
Fiorenzato's US distribution has improved in recent years. Several specialty coffee equipment dealers carry them, including some on Amazon. Availability is better in Europe and Australia, where the brand has stronger dealer networks. If you're in the US, budget for potential shipping costs from a specialty retailer.
How does the F4 compare to the Fiorenzato F64?
The F64 is a step up with larger 64mm burrs (same size, but redesigned geometry), a more refined adjustment system, and an electronic display. If you can stretch your budget by $300-400, the F64 is worth the upgrade for the improved workflow and slightly better grind quality.
Is the Fiorenzato F4 good for home espresso?
It's overkill for home use. The retention makes single-dosing wasteful, and the timed dosing system is designed for consistent, high-volume operation. A home-focused grinder in the $300-600 range will give you better results for how you'll actually use it.
How loud is the F4 compared to other commercial grinders?
At 72-75 dB, it's in the average range for commercial grinders. It's louder than the Mythos 2 (which has sound dampening) but similar to the Mahlkonig E65S and most Mazzer models.
Final Thoughts
The Fiorenzato F4 is the definition of quiet competence. It doesn't have the brand recognition of a Mahlkonig or the tech features of a Mythos, but it grinds well, lasts forever, and costs less than the big names. If you're opening a cafe on a budget or looking for a reliable second grinder, the F4 deserves a spot on your shortlist. Just make sure you pair it with a good scale, since the timed dosing isn't precise enough to skip weighing your doses.
