Understanding and History of Espresso Machines.
For connoisseurs of coffee, espresso is not a name that sounds foreign to the ear, but there are still many people who do not know the ins and outs or espresso history itself. Currently we are very easy to find espresso machines in various coffee shops, whether it's small or vice versa.
The espresso machine was first discovered by Angelo Moriondo in 1884, angelo was an Italian, precisely from Turin. The discovery of an espresso machine actually just happened far from the popularity of drinking coffee on the blue continent, europe is going on. The problem at that time was the deadline to make a cup of coffee takes about 10 minutes more, thus making long queues at the coffee shop.
On the basis of these problems, then came the idea of experts who live in Europe to make a machine that can brew a cup of coffee in a short time. Among these experts is an Italian who already kuta read on the Angelo Moriondo. Angelo's espresso machine is then patented. Machine Works Angelo Moriondo, became the forerunner of the modern espresso machine that we meet today in the corner of the coffee shop.
Espresso machines continue to be developed by two others namely Desidero pavoni with his friend Luigi Bezzerra, dedication they both in the world of espresso machine then gave birth to the first single-shot espresso machine. However, their work has not been able to manage the temperature and also the pressure because it is still heated using the heat of fire.
Furthermore, again an Italian genius named Pavoni, he perfected the shortcomings of the previous machine by presenting a thing on the machine, it was named valve release. Pavoni's work was published in 1906 in the Milan fair. [source]
