The coffee program decides the café's margin

Coffee is usually a café's largest single line by volume, its best margin, and the product customers judge hardest.

Most owners know the first two and manage the third by instinct. The three work together, and a change to one moves the others.

Cost the cup, properly

A cup costs the dose of coffee, the milk, the cup, the lid and the sugar, plus the shots poured away during calibration.

Those last two are what most costings miss. A café dialling in twice a day pours away real money, and nobody counts it.

Dose size is a lever nobody pulls

A gram on every double shot, across two hundred coffees a day, adds up to kilograms a week.

The right dose is the one that tastes right, not the smallest one. But a café that has never weighed it is guessing in an expensive direction.

Milk waste is bigger than coffee waste

Steaming more milk than the cup needs happens on every order during a rush, and the surplus goes down the sink.

Jug sizes matched to the drink sizes remove most of it, and the saving shows in the weekly order rather than on any till report.

The roaster relationship is worth more than the price

A good roaster trains staff, services the machine, lends equipment and tells a café when its grind has drifted.

A cheaper kilogram from a supplier doing none of that usually costs more once the training and the servicing land somewhere else.

Machine servicing is not optional

The group heads, gaskets and water filters all degrade steadily, and the coffee worsens so gradually that staff stop noticing.

A scheduled service, at an interval matched to the volume, keeps the product consistent. Our guide to servicing the equipment covers holding those dates.

Train every barista to the same standard

A café with three baristas and no agreed method serves three different coffees, and a regular notices immediately.

A written standard, covering dose, yield, time and milk texture, is what makes the product the café's rather than one person's.

Water changes the taste more than anybody expects

Mineral content affects extraction directly, and an exhausted filter changes the coffee while nothing else in the process changed.

A filter schedule, with dates on it, protects both the flavour and the machine's boiler from scale.

Takeaway cups deserve their own decision

Cups, lids and trays are a real line in the cost of a takeaway coffee, and prices move sharply with supply.

Reviewing that line yearly, alongside the bean price, is how a café notices a margin eroding a cent at a time.

Price the size difference honestly

A large coffee usually holds more milk and the same coffee, so pricing it as though both doubled overcharges the customer and distorts the mix.

Customers work that out quickly, and the ones who feel it stop ordering the large, which is the opposite of what the pricing intended.

Decaf and alternative milks are not an afterthought

Oat, soy and almond each behave differently under steam, and a café that treats them as one category serves two of them badly.

A surcharge, where the venue applies one, needs a reason a customer accepts. The cost difference is usually real and worth stating plainly.

Watch the coffee count, not the coffee revenue

Cups per day describes the café's foot traffic honestly. Revenue moves when prices change and hides a falling count entirely.

Both numbers together, week by week, tell an owner whether a quiet Tuesday is a trend or a public holiday.

What to change first

• The cup costing includes milk, packaging and calibration waste
• Dose weight gets measured rather than estimated
• Jug sizes match the drink sizes, to cut milk down the sink
• The roaster relationship gets valued for training and service, not price alone
• Machine servicing and water filters run on dated schedules
• A written standard covers dose, yield, time and milk texture
• Cups per day gets tracked beside coffee revenue
