La Marzocco Espresso Machine GB5 S

The **La Marzocco GB5 S** is available in **2-group, 3-group, and 4-group configurations**, where each “group” refers to a brew head used to extract espresso, directly affecting the machine’s capacity and workflow; the **2-group model** is compact (around 77 cm wide) and ideal for small to medium cafés, offering moderate output with lower power consumption and enough capacity for steady daily service, while the **3-group version** (about 97 cm wide) is considered the industry standard for busy coffee shops, providing higher productivity, larger boilers, and the ability to handle multiple baristas working simultaneously during peak hours, whereas the **4-group model** (around 121 cm wide) is designed for very high-volume environments such as large cafés, hotels, or chains, delivering maximum output with powerful steam capacity and the ability to produce a large number of drinks continuously; despite these size and capacity differences, all versions share the same core technologies including dual boilers for separate brewing and steaming, PID temperature control for precision, saturated group heads for thermal stability, and programmable dosing, ensuring consistent, high-quality espresso across all configurations.
