Decaf behaves differently in the drum — darker green, weaker first crack, faster after it, lower weight loss. What changes in the profile, why the probe matters more than the eye, and the four production consequences of adding a decaf SKU.
The count follows the menu, not the volume. When a second espresso grinder pays for itself, why decaf should not share, what a filter grinder is for, and how to spec each one.
A grinder is a motor, so frequency matters as much as voltage. Supply standards by region, what 50 vs 60 Hz does to burr speed, what dual-voltage models solve and what a transformer cannot.
A doser grinds ahead and dispenses by lever; an on-demand grinder grinds into the portafilter per shot. What each does to speed, freshness, waste and cleaning, and which bars still benefit from a doser.
A bundle checklist for opening a bar: the items that must be in the box on day one, the ones that should be, the ones that can wait — and the two that packages most often miss.
A pressurestat swings brew temperature by several degrees; a PID holds it within one. What that does to shot repeatability, why PID only pays off fully on a dual boiler with a rotary pump, and how to use it.
A flow meter that stops the shot buys consistency across baristas and speed on a rush, not better espresso. How volumetric dosing works, where it fails, and which bars should pay for it.
On a milk-drink bar the steam boiler, not the group count, sets the queue. How to turn drinks per hour into steam demand, why litres and kilowatts must be read together, and what the common sizes mean.
Power decides everything on a mobile bar. How to size a generator or shore connection, feed a rotary-pump machine from a tank, handle drainage, and which machines fit which kind of mobile business.
Roasting is rarely the bottleneck; packing is. Staffing bands from under 100 kg to over 2,000 kg a week, where the hours actually go, and which equipment removes a person from the line.
