Espresso machine
An espresso machine brews coffee by forcing hot water through finely-ground coffee beans under high pressure, typically around nine bars. This process quickly extracts rich flavors and creates a concentrated shot of coffee known as espresso. The machine heats water, presses it through the coffee, and maintains the necessary pressure, often with a built-in pump. Many espresso machines also include steam wands to froth milk for drinks like lattes and cappuccinos. They vary from simple models to sophisticated appliances with precise temperature and pressure controls, enabling users to produce café-quality espresso at home or in commercial settings.
