The Sole is a heat-exchanger machine with the E61 group, the café lever group, heated by the natural circulation of water: a single boiler makes the steam and heats the brew water, so milk can be steamed while the coffee runs. The pump is rotary and draws either from the four-litre tank or from the mains: you can start on the tank and plumb it in later.
A PID holds the temperature and a timer counts the seconds of each shot. On request, the group can be fitted with a paddle to vary pressure during extraction, and the pump with flow control: additions for anyone who wants to go beyond the basic recipe. If the tank runs dry, the machine switches off the heating element by itself, and the boiler refills automatically.
It is for someone who wants a café group in the kitchen and the freedom to decide later whether to plumb it in. Like every E61 group, it needs switching on well before the first coffee; and at 45 cm deep it wants a generous counter.

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.
Double espresso, sugar syrup and ice in a shaker. It has no specification: it has a house recipe.
