Fracino F4 Grinder Review: On Demand vs Automatic for Cafés (UK)
Last updated: October 2026
In 30 seconds:
- The Fracino F4 is a compact, British-built café grinder with 58 mm flat burrs — made for small to medium coffee shops, kiosks and coffee vans.
- It comes in two versions: F4 On Demand (grinds fresh for every shot, from £699) and F4 Automatic (a doser that fills a chamber, from £559).
- The On Demand grinds a 7 g espresso dose in about 3.5 seconds — quick enough for a steady queue, not a 300-cup rush.
- It’s small: 430 mm tall, 194 mm wide, with a 500 g hopper — it fits beside a 1- or 2-group machine without eating your counter.
- Biggest buyer mistake: picking the cheaper Automatic to save £140, then wasting stale grounds every quiet afternoon.

Who is the F4 for? Cafés, kiosks and coffee vans doing up to a couple of hundred cups a day. It’s the grinder you pair with a Cherub, Little Gem, Piccino or a 2-group Contempo.
Why flat burrs? Two flat discs grind the bean evenly. Even grounds mean the water flows through the coffee evenly — so your shots taste the same at 3pm as they did at 8am.
On Demand or Automatic? On Demand grinds straight into the handle each time you press it. The Automatic grinds a batch into a doser chamber you then click out. Fresh is better, but the doser is cheaper and very quick in a rush.
The honest summary: the F4 is a solid, no-fuss grinder for small and mid-sized shops. Buy the On Demand unless your budget truly can’t stretch, and step up to the F6 if you regularly serve a lunchtime queue out of the door.
Fracino F4 On Demand
Quick specs
- Type: on-demand (grinds fresh per shot, straight into the portafilter)
- Burrs: 58 mm flat
- Dose speed: about 3.5 seconds for a 7 g single shot
- Hopper: 500 g beans
- Motor: 300 W, 1,400 rpm
- Size: 430 (H) × 194 (W) × 308 (D) mm
- Price: from £699 (SKU F4-OD)
Best for: cafés and coffee vans that want fresh-ground coffee for every cup, with no waste at quiet times.
What it does well
- Grinds only what you need — nothing goes stale in a doser.
- Consistent doses once you’ve set it, so every barista pours the same shot.
- Slim enough to sit beside a 1- or 2-group machine on a small counter.
Don’t buy it if
- You run a 3-group machine flat out — the slower 3.5 s dose will hold up the line.
- You need to grind for filter batches as well as espresso all day.
Trade-off: 3.5 seconds a dose is fine for a steady queue. For a non-stop rush, the F6 On Demand (3 s, 65 mm burrs) keeps up better.

Fracino F4 Automatic (doser)
Quick specs
- Type: automatic doser (grinds into a chamber, you click doses out)
- Burrs: 58 mm flat
- Hopper: 500 g beans
- Motor: 300 W, 1,400 rpm
- Size: 430 (H) × 194 (W) × 308 (D) mm
- Price: from £559 (SKU F4-AUTO)
Best for: busy stalls and events where speed matters more than every last bit of freshness, and the budget is tight.
What it does well
- Very quick in a rush — the dose is already ground and waiting.
- Simple to use, with nothing to programme.
- Same compact body as the On Demand.
Don’t buy it if
- You have long quiet spells — ground coffee in the doser goes stale within minutes.
- Taste consistency matters more to you than the £140 saving.
Trade-off: you save money up front but tend to throw away more coffee. Only grind what you’ll use in the next few minutes.

F4 or F6 — which Fracino grinder do you need?
- Pick the F4 if you serve a steady flow of customers with a 1- or 2-group machine and space is tight.
- Pick the Fracino F6 if you have regular rushes. Its bigger 65 mm burrs and 3-second dose keep pace with a busy 2- or 3-group machine.
- Both are Fracino-built and use the same simple controls, so your team won’t need retraining if you upgrade later.
Setting up your F4 on day one
- Site it on a solid, level counter next to the machine, near a 13 A socket.
- Fill the hopper with fresh beans — no more than you’ll use in a day or two.
- Start a little coarse, then grind and pull a test shot.
- Adjust in small steps until a double runs in about 25–30 seconds.
- Set the dose time (On Demand) so each press gives the same weight. Check it on scales.
Our step-by-step guide to dialling in a grinder walks through this in detail.
Looking after it
- Daily: brush out the chute and wipe the hopper. Old oily grounds make coffee taste bitter.
- Weekly: run grinder-cleaning tablets through it — here’s how to clean a grinder without harming the burrs.
- Watch the burrs: blunt burrs give slow, uneven shots. Our guide shows when to replace grinder burrs.
- Warranty: Fracino repairs are back-to-base — the grinder goes to the workshop rather than an engineer coming to you. Plan a spare or back-up for busy weeks.
Frequently asked questions
What is the difference between the Fracino F4 On Demand and F4 Automatic?
The On Demand grinds fresh coffee for every shot, straight into the handle. The Automatic grinds a batch into a doser chamber that you click out. On Demand gives fresher, more consistent coffee; the Automatic is cheaper and very quick in a rush.
How fast does the Fracino F4 grind a shot?
The F4 On Demand grinds a 7 g single dose in about 3.5 seconds. That suits a steady café queue. For heavy rushes, the F6 On Demand is quicker at about 3 seconds.
What size burrs does the Fracino F4 have?
58 mm flat burrs on both versions. That’s plenty for small and medium cafés. The F6 steps up to 65 mm burrs for higher volume.
How much does the Fracino F4 grinder cost?
The F4 Automatic is from £559 and the F4 On Demand is from £699 at MobCater.
Is the Fracino F4 good for a coffee van?
Yes. At 430 mm tall and 194 mm wide it’s compact, and its 300 W motor runs from a normal 13 A supply. Allow for that load if your van runs on a generator.
How big is the F4 hopper?
500 g of beans. Only fill what you’ll use in a day or two so the beans stay fresh.
Which coffee machines pair well with the F4?
The F4 suits 1- and 2-group machines such as the Fracino Cherub, Little Gem, Piccino and Contempo 2 Group. With a busy 3-group, choose the F6.
How is the F4 repaired under warranty?
Fracino warranty repairs are back-to-base. The grinder goes back to the workshop rather than an engineer visiting you, so it’s worth planning a back-up for busy periods.
