The first Coffee Machine
The first patent for an espresso coffee machine dates back to 1884 and was designed by Angelo Moriondo. It was a device for making espresso coffee presented on the occasion of the General Exhibition at Valentino.
The merit of having industrialized the espresso machine is however to be attributed to the Milanese Luigi Bezzera who in 1901 obtained the first of his patents.
He designed this instrument in much the same way as the machines, which were then widely distributed, thanks above all to another pioneer of the time, Desiderio Pavoni. The latter sensed the great potential of the espresso and developed its commercialization in the local public, and it was with his company La Pavoni that he started producing the machine.
The espresso machine by itself, was a large vertical cylinder, containing a brass boiler kept under pressure by a gas stove. On the side of the boiler were placed the groups in which coffee was placed. Turning a tap the boiling water and the steam contained in the boiler passed through the coffee with about 1.5 atmospheres, and in a minute the coffee was done.
Since then, great progress has been made and the coffee machine has undergone great changes and evolutions, to become that machine present in all the Bars that we all know.
There are also highly automated coffee machines, where pressing a button grinds the coffee, press it and maybe whisk the milk without the operator having to intervene minimally if not to serve the cup to the customer. Today, there are also very sophisticated coffee machines that, on the contrary, the barista can set and customize as and more than one computer, choosing pressure and temperature depending on the type of coffee and every form of experimentation.
In short, the world of coffee never ceases to amaze, a world in continuous growth, where however the spirit of this drink will always remain unchanged.
