La Pavoni Spa was founded in Milan in 1905 thanks to Desiderio Pavoni in a little workshop at Via Parini. His first invention was patented by Luigi Bezzera, on 1st September 1902, duly registered at the Milan State office on 19th September 1903, and gave life to the first espresso coffee machine for bar called “Ideale”.
It was a vertical machine, with a boiler kept at a constant pressure by a gas-ring which it rested on, or by means of electricity, with side brewing groups (from 1 to 4) supported by inside hooks and had a filter for ground coffee.

By opening a knob, at a pressure of 1,5 bar, water first and then steam passed through the ground coffee in the filter, enabling the brewing of the espresso, which – in one minute – was ready in the cup; the machine was also fitted with some knobs to get hot water or steam to prepare hot drinks.
Being the first machine of it’s kind to be marketed, this model spread the fashion of drinking Italian style “espresso” coffee at the bar, in Europe, first, and then around the whole world.

This system of obtaining the coffee and the mechanics of the machines remained the same till the post-war period, although it sometimes created a sour, “burnt” taste, caused by the fact that – while brewing – steam (in addition to water) was let through the coffee.
In 1948 a new system was introduced. Water was taken from the boiler under pressure. It was then filtered through the coffee by means of a piston pushed by a spring at ten bars pressure; the coffee no longer had that burnt taste.
