The Mahlkönig E64 WS is an electric espresso grinder for the home, fitted with steel burrs. It doses the grams of coffee with precision. Dialling in is assisted: the screen guides the user step by step through creating a recipe, and the espresso brew time can be entered by hand so that the grind size is adjusted automatically. Zero calibration is done without tools, guided on screen. The Sync app handles pairing, automatic software updates and usage tracking. The spout has a ball joint and the ambient lighting is customisable.

Seven grams, twenty-five seconds, twenty-five millilitres: Italian espresso has a written specification, and this is it.
The same dose as an espresso, less water in the cup. No institutional source fixes its volume — so here you will only find what is documented.
25 ml of espresso and 100 ml of steamed milk, in a 150–160 ml cup. The cappuccino has a specification too.
An espresso and a stain of milk. How much milk, exactly? No source declares it — and we do not invent it.
An espresso lengthened with hot water. The amount of water is set by no standard: it changes from country to country and from bar to bar.
The moka is not dosed in grams: it is dosed by volume. Water up to the valve, funnel filled level, never tamped.
