Four group espresso machines—like the La Marzocco Linea PB and Linea Classic—are built for speed, volume, and consistency. With the ability to pull four shots at once, these machines drastically boost output, making them ideal for high-volume cafés, bars, restaurants, and drive-thrus. Whether you're running multiple baristas or need to keep up with peak rushes, a 4 group espresso machine ensures fast, reliable service without compromising quality.
