Single-Dose vs Hopper Grinder for a Coffee Shop (UK Guide)
Last updated: September 2026
A single-dose grinder makes you weigh and load beans for every shot. A hopper grinder holds a day of beans and grinds on demand. For a UK coffee shop, the hopper is the standard choice, with doser models from £349 and on-demand models from £389.
Most cafés with a queue choose a hopper on-demand grinder because it removes a step from every drink. Single-dose suits low-volume, bean-swapping set-ups. This guide helps you decide, using the specs of the Fracino hopper range we sell. New to grinders? Start with our coffee grinders for coffee shops guide.
In 30 seconds:
- Single-dose: you weigh each dose, tip it in, grind it all. Least waste, slowest service.
- Hopper doser: grinds into a chamber, you pull a lever. Fast, but ground coffee sits and ages.
- Hopper on-demand: grinds the exact dose when you press a button. The best fit for a busy counter.
- We stock hopper grinders only, from 250g to 2kg hoppers. We do not sell a single-dose model.
- Busy counter: choose on-demand. Slow kiosk with rotating beans: single-dose is worth a look.
Quick specs: the hopper range we sell
- F2 Specialty On Demand: 250g hopper, 7 seconds per 7g shot, 50mm flat burr.

What a single-dose grinder does
You weigh your beans on a scale, tip them into a small hopper and grind the lot. Nothing is left sitting in the grinder. That means very little stale coffee and an easy switch between beans.
The cost is time. Every shot needs a weigh, a pour and a purge. That is fine for a specialty bar making a few drinks an hour. It slows down a queue.
What a hopper grinder does
A hopper holds your beans above the burrs. A doser grinds into a chamber, and you dose with a lever. An on-demand grinder grinds the shot when you press a button, so the coffee is fresh and the barista keeps working.
The trade-off is that beans sit in the hopper. Light, air and warmth from the motor all age them. Fill it for the day, not the week.
Single-dose vs hopper: side by side
| Question | Single-dose | Hopper on-demand |
|---|---|---|
| Speed at the counter | Slow: weigh every dose | Fast: press and grind |
| Stale coffee risk | Very low | Low, if you fill for the day |
| Changing beans | Easy | Needs a purge of the chute |
| Best daily volume | Low | Medium to high |
| Staff skill needed | Higher | Lower |
How much coffee does a hopper hold?
At an 18g double dose, a 250g hopper covers about 13 shots. A 500g hopper covers about 27. A 1kg hopper covers about 55. Match the hopper to your busiest day, then fill it once each morning.
The biggest mistake: buying for the look, not the queue
Single-dose grinders are fashionable, so many new owners buy one without counting shots. Then the Saturday queue builds while the barista weighs beans. The reverse mistake is a huge hopper in a quiet kiosk, which leaves beans sitting for days.
Count your likely shots per hour first. If you pull more than a few dozen a day, pick an on-demand hopper model. Our Kenia-tron On Demand grinder has a 1kg hopper and is in stock from £449.
What you need either way
- A grinder that suits your daily shots, not your busiest imaginable day.
- A set of scales to check your dose, even with an on-demand model.
- A weekly clean of the hopper and burrs. See how to clean a coffee grinder.
- A dial-in routine each morning. See how to dial in a coffee grinder.
- A plan for static and clumping, which affects both types. See fixing static and clumping.
Frequently asked questions
What is a single-dose grinder?
A single-dose grinder is a coffee grinder you load with one weighed dose of beans at a time. You grind everything you add, so almost nothing is left inside. It gives fresh grounds and easy bean changes, but it adds a weigh-and-pour step to every drink.
Is a single-dose grinder good for a busy coffee shop?
Usually not. Weighing and loading beans for every shot adds seconds to each drink, and those seconds pile up in a queue. A hopper on-demand grinder is the usual choice for a busy counter, because the barista simply presses a button and keeps working.
What is the difference between a doser and an on-demand grinder?
A doser grinds into a chamber, and you release a dose with a lever. An on-demand grinder grinds the exact dose when you press a button. On-demand keeps coffee fresher because grounds never wait. Doser models cost less, starting from £349.
How many shots does a coffee grinder hopper hold?
At an 18g double dose, a 250g hopper holds about 13 shots, a 500g hopper about 27, and a 1kg hopper about 55. Choose a size that covers a normal busy day, then refill it each morning rather than topping up all week.
Do hopper grinders make stale coffee?
Only if you overfill them. Beans in a hopper meet light, air and motor warmth, so they age faster than sealed beans. Fill the hopper for the day, keep the lid on, and choose an on-demand model so ground coffee is never left waiting.
How much does a hopper coffee grinder cost in the UK?
Doser hopper grinders start from £349. On-demand hopper grinders start from £389 and rise to £899 for larger-burr models. Prices change, so check the live product page before you order and compare hopper size and shot time.
Can I switch between two beans on a hopper grinder?
Yes, but you need to purge. Empty the hopper, run the burrs until the chute is clear, then load the new beans. If you switch often, for example between regular and decaf, a second small grinder is easier than constant purging.
Which grinder should a new coffee shop buy?
A new coffee shop serving a steady queue of espresso should buy an on-demand hopper grinder. The Kenia-tron On Demand has a 1kg hopper and grinds a 7g shot in 2.8 seconds. It is in stock from £449 on the product page.
