Brand New La Marzocco GS3 AV In Gloss White

GS is gruppo saturo — Italian for saturated group. The name points straight at the reason the machine exists: a saturated brew group, the same design used in La Marzocco's cafe machines, in a single-group body that fits on a bench.

The group is a solid brass block integrated into the coffee boiler rather than a separate assembly fed from it. There is no temperature drop between boiler and coffee, and the PID's reading tracks what is actually happening at the group. It is the single biggest reason the GS3 holds temperature the way it does.

No. The AV programmes dose and pre-infusion, then runs the shot at pump pressure and stops at the set volume. Manual control of flow and pressure through the extraction is what the MP paddle is for. If you want to shape pressure by hand, buy the MP; if you want the same shot every time with less involvement, the AV is the right machine.

No. The GS3 runs from its own water reservoir or can be direct plumbed, so it works in a kitchen without plumbing changes and in a cafe with them. The rotary vane pump is quiet either way.

Around thirty minutes to full brewing and steaming temperature. That is the trade-off of commercial-grade thermal mass, and it is why most owners run it on a schedule through the La Marzocco Home App rather than switching it on and waiting.

The steam boiler is 3.5 litres, which is a genuinely commercial figure for a single-group machine. Back-to-back milk drinks are not a problem, and the steam is dry enough for proper texturing rather than just heating.

It is designed as a home and light-commercial machine — well suited to small cafes, restaurants, offices, roastery tasting bars and training benches. For continuous high-volume service you want a multi-group machine instead.

Somewhere level and ventilated, water either by reservoir or a mains connection, and an appropriate electrical supply. Have a licensed electrician confirm your supply before installation, and have a qualified technician handle commissioning if it is being plumbed in.

An unused machine as current production. The GS3 is built to be serviced and kept running for decades rather than replaced, so buying new means the whole of that life is ahead of it.
