3. How does an espresso machine make coffee so strong?It heats water to about 195-205°F (90-96°C) and pushes it through the coffee at high pressure, about 9 bars, which extracts flavors quickly and makes a dense, aromatic drink.
4. Why do espresso machines need high pressure?High pressure pushes the water through the coffee quickly, pulling out oils, sugars, and acids that give espresso its rich taste and a creamy layer called crema on top.

Channeling: Uneven water flow through coffee grounds, leading to poor extraction and weak espresso.
PID Controller: A system that precisely regulates temperature, crucial for consistent espresso brewing.
Volumetric Pump: A pump that dispenses a pre-set volume of water, ensuring shot consistency.
