Espresso Machines

The classic Italian Espresso is the result of hot water at about 88 °C which crosses the 7 grams of coffee contained in the arm of the espresso machine. So why is there a difference between an espresso and another? Much depends on the care with which your barman treats his espresso machine and the coffee he bought. Always pay attention to how the coffee is pressed (the arm of the machine must be placed). The excess coffee must be removed from the edges otherwise it may burn during delivery. Furthermore, before each delivery, the machine should be activated for a few seconds without the arm inserted, so as to eliminate any previous coffee residues. The cup in which you will be served coffee should be of thick porcelain or, if you prefer, glass.
