The characteristics of the drink extracted changed, thanks to two important technical innovations: the reduction of the water temperature from 248 ☏ to 194 ☏– which helped to eliminate that unpleasant aftertaste which was still typical in the coffee – and the increase in pressure which came up to about 9 atmospheres (before it was1,5) creating the froth, the distinguishing feature of the espresso. This novelty was the basis for the espresso machine we know today. In order to produce an espresso, you had to turn a tap: the boiling water and the steam passed through the coffee and the extraction took about one minute.Īt the end of World War II, in 1945, Angelo Gaggia started up production of a different model of espresso machine, based on a system of levers. Positioned at the side of the boiler were dispensers in which the coffee was placed. How was a bar espresso machine made at that time? It was very different to the versions that we are used to today: in fact they consisted of a large vertical cylinder with a brass boiler inside, heated by a gas hob. Well aware of the potential of that invention, Luigi Bezzera sold the patent to the company La Pavoni, who started up production on an industrial scale. Luigi Bezzera and La Pavoniīezzera drew inspiration from Moriondo’s espresso machine to design his own, which he then patented in 1902. The name of this industrialist is actually not known to many, who attribute this invention to Luigi Bezzera instead.
Indeed, Moriondo had imagined that this device could attract more customers. Moriondo, though, never wanted to produce his invention on an industrial scale, he limited himself to the traditional construction of just a few prototypes for use in his business activities. The first patent for an espresso machine dates back to 1884 and bears the name of Angelo Moriondo, an industrialist from Torino who had understood how convenient it was to be able to prepare coffee in a short time and enjoy it as soon as it was made.

In the years just before and during World War I, the number of patents fell, but at that time the first patent was granted for the portafilter and the automatic machine, both granted to Pier Teresio Arduino. If up until 1910 from 1 to 5 patents were granted every year, in 1911 there were 15 and in 1913 as many as 22. It was not immediately successful, but many people recognized its potential and so tried to exploit it by registering a patent, over the following years. The first machine for making espresso coffee was built around the end of the 19th century, in Italy. Are you ready to hear about its history? The invention of the espresso coffee machine
Espresso coffee series#
There is one in particular though, that represented a real revolution: the invention of the espresso machine for bars, which has undergone a whole series of evolutions and changes to become the instrument that we all know today and which we see every day behind the counter. There are also many inventions linked to its consumption, such as that of the coffee cup, for example.
The most famous Italian drink in the world has a long history: the coffee plant, in fact as we have seen, it arrived from very far away, Ethiopia probably and the spread of consumption occurred above all following trade exchanges between East and West, but also as a consequence of certain wars.
