La Marzocco GB5 S AV Espresso Machine

The La Marzocco GB5 S AV is a professional-grade multi-group espresso machine designed for high-volume commercial environments like coffee shops, restaurants, and hotels. The "GB5" name comes from the initials of Giuliano and Bambi, two of La Marzocco's founders. The "S" signifies its modern electronic system, and "AV" stands for Auto-Volumetric, meaning it can automatically brew shots to a pre-set volume.

Key Features

Dual Boiler System: The GB5 S features a dual boiler system, with separate boilers for brewing and steaming. This design ensures absolute temperature stability for espresso extraction, as the brew boiler's temperature is independent of the steam boiler. This is critical for pulling consistent shots in a fast-paced setting.

PID Temperature Control: The machine uses dual PID (Proportional-Integral-Derivative) controllers for precise and highly stable temperature regulation in both the brew and steam boilers. This level of control allows baristas to fine-tune temperatures for different coffees and provides consistent results shot after shot.

Auto-Volumetric Dosing (AV): With the auto-volumetric feature, a barista can program the machine to dispense a specific volume of water per shot. This allows for unparalleled shot-to-shot consistency and reduces the need for constant manual monitoring, which is essential in a busy café.

Pre-Heater System: The machine includes a pre-heater that warms the water before it enters the brew boiler. This reduces the energy needed to heat the water to the final brewing temperature, improving the machine's efficiency and temperature stability.

Saturated Brew Groups: Like other La Marzocco machines, the GB5 S features saturated brew groups. These groups are directly integrated with the brew boiler, ensuring that the water temperature is perfectly consistent from the boiler to the coffee grounds. This prevents temperature drops and contributes to a stable extraction.

Proportional Valve Technology: The new proportional valve technology in the S series improves control over the hot water dispenser, allowing baristas to more accurately manage the flow and temperature of the water.

Ergonomics and Design: The GB5 S is designed with barista workflow in mind. The redesigned chassis provides more space for the barista to work, and the drip tray is strategically positioned to make the workflow more efficient. The classic stainless steel body and clean lines give the machine a timeless, professional appearance.

Advanced Electronics: The machine's electronic system can track key metrics like total shot volume, number of shots per group, and machine usage statistics. This data is invaluable for cafe owners who want to monitor efficiency and optimize their workflow.

The La Marzocco GB5 S AV is a workhorse designed for performance, precision, and consistency under pressure. It's a machine built for a professional environment where speed, quality, and reliability are paramount.
