The Espresso Machine

An espresso machine brews a concentrated coffee by forcing hot water through finely ground coffee at high pressure. It typically uses a boiler or heating element to achieve the optimal temperature, and a pump to generate pressure around 9 bars. The result is a rich, robust shot with a layer of crema on top. Espresso machines can be manual, semi-automatic, automatic, or super-automatic, offering varying levels of control and convenience. They are widely used in cafes and homes for making espresso-based drinks like lattes and cappuccinos. Proper maintenance and grinding are key to achieving high-quality espresso.
