Overview
Designed for coffee drinkers who care deeply about filter brewing, grind consistency, and freshness, the Fiorenzato AllGround ProBrew Single Dose Coffee Grinder takes a more specialized approach than a traditional multi-purpose grinder.
Rather than trying to cover every brewing method, the ProBrew is engineered specifically around filter coffee.
Its 64mm flat Dark-T burrs use a geometry designed for filter brewing, while a low-retention single-dose workflow helps reduce stale grounds and unnecessary coffee waste when switching between coffees.
Grind size is adjusted through a micrometric ring system with 10-micron increments, allowing precise changes across brewing methods ranging from delicate pour-over recipes to coarser immersion brewing.
With approximately 0.1–0.2g retention, a stainless-steel dosing cup holding up to 50g, a 250W motor, and a compact Italian-designed body, the ProBrew is built for enthusiasts who weigh their coffee, experiment with different beans, and want each dose ground fresh.
For the filter-coffee drinker who values repeatability and control more than one-grinder-for-everything versatility, the ProBrew is a focused premium solution.

Why This Product Stands Out
The ProBrew is not simply an AllGround with a different accessory package.
Its defining difference is specialization.
Where many premium grinders are designed primarily around espresso and then stretched toward coarser brewing, the ProBrew starts with the needs of filter coffee.
That means emphasis on:
- Filter-specific burr geometry
- Precise grind-size adjustment
- Low retention
- Single-dose workflow
- Easy coffee-to-coffee switching
- Clean transfer into a dosing cup
For enthusiasts who frequently rotate between single-origin coffees, different roast profiles, or different brewing recipes, those characteristics matter.
Instead of leaving old grounds in the chamber or committing a hopper full of beans to one coffee, the ProBrew supports a more deliberate workflow:
weigh → grind → brew → repeat
Designed Around Filter Coffee
The ProBrew's burr geometry is specifically intended for filter-focused grinding.
That makes it especially well suited for methods such as:
- Pour-over
- V60-style brewing
- Flat-bottom drippers
- Chemex-style brewing
- Batch filter
- Immersion brewers
- French press
Its adjustment system provides enough control to move from finer filter settings toward substantially coarser grinds without requiring a second grinder.
64mm Dark-T Flat Burrs
At the center of the ProBrew are 64mm flat Dark-T burrs.
The Dark-T treatment incorporates:
- Titanium
- Aluminum
- Carbon
- Nitrogen
Fiorenzato provides significantly extended wear resistance compared with standard burrs.
For the ProBrew, the supplied rated burr life is approximately 3,000 kg of coffee.
That specification reinforces the grinder's position as a long-term enthusiast tool rather than a disposable countertop appliance.
Very Low Retention
Single dosing works best when the amount of coffee entering the grinder closely matches the amount coming out.
The ProBrew is rated at approximately:
0.1–0.2g retention
That is particularly useful when:
- Switching between different coffees
- Comparing roast profiles
- Adjusting recipes
- Brewing expensive specialty coffee
- Trying to minimize stale grounds
- Reducing waste between doses
Low retention also helps make recipe changes easier because less coffee from the previous grind remains inside the grinder.
10-Micron Micrometric Adjustment
The ProBrew uses a ring-nut micrometric adjustment system with approximately 10μm per step.
This provides controlled, repeatable changes in grind setting without relying on broad, widely spaced consumer presets.
For filter brewing, those smaller adjustments can help refine:
- Drawdown time
- Extraction rate
- Flow resistance
- Brew balance
The goal isn't simply "fine" or "coarse."
It's the ability to make incremental changes until a particular coffee behaves the way you want in a specific brewer.
Single-Dose Workflow
Rather than using a traditional bean hopper, the ProBrew is optimized around measuring individual doses.
A typical workflow might be:
- Weigh the coffee.
- Add the dose to the grinder.
- Select the grind setting.
- Grind into the stainless cup.
- Transfer grounds into the brewer.
- Repeat with a different coffee or recipe when desired.
This makes the ProBrew especially attractive for enthusiasts who buy multiple coffees at once rather than keeping one blend permanently loaded into a hopper.
Stainless Steel Dosing Cup
The included stainless-steel cup holds up to 50 grams.
That capacity supports:
- Single-cup pour-over
- Large pour-over recipes
- Multi-cup filter brews
- French press
- Other higher-dose filter methods
Grinding into a removable cup also helps keep the workflow cleaner and makes transfer to different brewer shapes easier.

AllGround ProBrew vs. AllGround
These two grinders share Fiorenzato's premium home-grinder DNA, but they are designed for different customers.
| Feature | AllGround ProBrew | AllGround |
|---|---|---|
| Primary Focus | Filter brewing | Espresso, Moka & filter |
| Workflow | Single dose | Hopper / multi-method |
| Burr Size | 64mm | 64mm |
| Burr Type | Filter-specific Dark-T | Multi-method Dark-T |
| Retention | 0.1–0.2g | Not specified in supplied data |
| Adjustment | 10μm micrometric steps | Continuous micrometric |
| Dosing Cup | 50g stainless steel | Grounds container |
| Hopper | Single-dose focused | 250g hopper |

Choose the AllGround if you regularly move between espresso, Moka, and filter coffee.
Choose the AllGround ProBrew if filter brewing is the priority and you want a single-dose, low-retention grinder optimized specifically for that style of coffee.
Why Single-Dose Brewers Will Appreciate It
If you keep several bags of coffee open at once, a large bean hopper can become inconvenient.
The ProBrew avoids that commitment.
You can grind:
18g of one Ethiopian coffee
then:
30g of a Colombian coffee
then:
50g for a larger batch brew
without filling and emptying a hopper between recipes.
Combined with its very low stated retention, that makes the grinder particularly attractive for people who treat coffee as something to explore rather than simply replenish.
Compact but Substantial
At just 6.6 inches wide, the ProBrew occupies relatively little lateral counter space.
Yet its 20-pound weight and 64mm burr platform give it a more substantial feel than many small home grinders.
Its lower 15.25-inch height also makes it easier to place beneath cabinetry than taller hopper-based grinders.
Quiet, Refined Operation
Fiorenzato designed the AllGround family with attention to noise and vibration.
For home users, that's especially useful during:
- Early mornings
- Shared-household routines
- Apartment living
- Open kitchens
- Home-office use
The grinder is still a mechanical coffee grinder, but its housing is designed to make the process more refined than many commercial-style alternatives.
Care & Cleaning
Routine maintenance helps preserve grind consistency and low-retention performance.
Recommended practices include:
- Brush loose coffee from the dosing area.
- Keep the stainless dosing cup clean and dry.
- Remove accumulated grounds according to Fiorenzato's instructions.
- Follow the operating manual when accessing the burr chamber.
- Never introduce water directly into the burr mechanism.
- Disconnect power before deeper cleaning or maintenance.
Use only manufacturer-approved procedures when removing or servicing burrs.
