What is a espresso machine and how does it work?
An espresso machine is a specialized coffee machine that brews a concentrated coffee beverage called espresso. It works by forcing hot water through finely ground coffee beans at high pressure. The machine has a group head where the ground coffee is placed and a portafilter that holds the coffee. The water is heated in a boiler and forced through the portafilter by a pump. The result is a strong, rich and creamy espresso shot that is the base for many coffee drinks like cappuccinos, lattes, and macchiatos. There are many types of espresso machines, from manual lever machines to fully automatic machines, each with their own unique features and brewing methods.
