An office machine has a harder job than a cafe machine in one respect: no barista. It has to be operated by everyone, cleaned by almost nobody, and produce a drinkable flat white at 9am when eleven people want one at once. That rules out most of what looks appealing in a showroom.
Start with cups per day
Count heads, multiply by two coffees, and be honest about the peak. Twenty people is not twenty coffees spread over eight hours, it is twelve between 8:45 and 9:30.
- Up to about 30 cups a day: a compact bean to cup machine on a bench.
- 30 to 100 cups: a full size automatic with a milk system and a dedicated fridge.
- 100 plus, or a client-facing space: a commercial machine and someone trained to run it, which changes the whole equation.
Bean to cup is almost always the answer
A bean to cup machine grinds, doses, tamps, brews and textures milk at the touch of a button. The coffee is not as good as a well pulled shot, but it is far better than what an untrained user gets from a manual machine, and it is consistent at 4pm on a Friday. Consistency is the whole point in an office.
Look for: a grinder built in, adjustable strength and volume, a rinse cycle that runs automatically, and a drip tray big enough that it does not need emptying twice a day.
Milk is where offices fail
Milk systems either draw from a carton in a fridge or from a jug you fill. The fridge version wins in a real office: it keeps the milk safe, it holds enough to get through the morning, and there is no jug sitting warm on the bench.
A dual milk fridge lets you offer dairy and a plant milk at once, which in an Australian office is no longer a nice-to-have. Look for direct cold storage rather than fan forced cooling, because less air movement means the milk holds condition longer.
Plumbed or tank
A tank machine can go anywhere but needs refilling, and it will be empty precisely when the client arrives. A plumbed machine never runs out and takes a water filter inline, which also protects the boiler from scale. If the space allows plumbing, plumb it.
Plan the maintenance before you buy
Somebody has to empty the grounds drawer, refill the beans, run the milk clean cycle and replace the water filter. Decide who, or buy a machine with a service agreement. The most common cause of a dead office machine is not a fault, it is scale and sour milk lines.
The cleaning routine is the same principle as any machine: see how to descale an espresso machine.
The beans matter more than people expect
Bean to cup machines suit a medium to medium-dark roast with body, because most office drinks are milk based, and they dislike very oily dark roasts, which clog the grinder and the chute. We go through this properly in best coffee for bean to cup machines.
