La Marzocco GS3 AV 1GR Espresso Machine

The La Marzocco GS3 AV espresso machine is a single-group model with programmable doses, designed for places where consistency and an efficient workflow matter. The button panel runs saved doses, so the barista does not have to stop every shot by hand. Two independent boilers, a saturated group and separate PID control for coffee and steam form a stable base for everyday espresso work.

How does the AV system change espresso work?

The AV version lets you programme doses and run them with buttons on the panel. Once the cycle has started, the machine stops delivering water at the programmed point by itself, so the barista can steam milk, prepare the next portafilter or serve a finished drink in the meantime.

Automatic dosing is especially useful when several people use the machine or when several orders have to be made to the same recipe in a short time. It does not replace setting the grinder correctly, weighing the coffee or preparing an even puck, but it removes one variable from daily service.

GS3 AV or GS3 MP: which version will suit you better?

The GS3 AV is the better option for users who want to save doses and make espresso to a repeatable routine. Instead of a panel of programmed doses, the GS3 MP has a paddle lever that lets you control pre-infusion and water flow by hand during every shot.

The La Marzocco GS3 AV is 37,999 zł gross, and the GS3 MP 37,182.20 zł gross. The difference is 816.80 zł, so the choice should not come down to saving money. The AV better fits a venue, office or home where easy repetition of recipes matters, while the MP is mainly for someone who deliberately uses manual extraction control.

Does the La Marzocco GS3 AV make sense in a small café?

The GS3 AV can work as the main machine in a small café, restaurant, showroom or bar with calm, predictable traffic. Programmable doses make it easier to operate, and the separate boilers let you brew espresso and use steam without a shared water circuit.

You do have to allow for the limit of a single group. At busy times you cannot run several extractions at once or comfortably split the work between two baristas, so in a café with high drink sales a two-group machine will be more productive. The GS3 AV can, however, serve as an extra station for decaf, a separate coffee or an espresso that needs a different temperature.

Compared with the Linea Mini R at 24,399 zł gross, the GS3 AV costs 13,600 zł more. Both models have two boilers and a saturated group, so choosing the GS3 AV is justified mainly when dose programming and a more professional way of organising the station will actually be used. For making a few coffees a day at home, the Linea Mini R may be the more sensible choice.

Two circuits, stable temperature and steam

The brew boiler has a capacity of 1.2 l and the steam boiler 3.5 l. The temperature of both circuits is controlled independently by PID, and a heat exchanger preheats the water used for brewing. The saturated group helps limit temperature fluctuations from one extraction to the next.

The machine has a professional steam wand, a separate hot water outlet and a 58 mm portafilter. It can draw water from a 3.5 l tank or be plumbed in, so the installation can be matched to where it will be used.

The body is made of stainless steel. The La Marzocco GS3 AV is 41 cm wide, 53 cm deep and 35.5 cm high, weighs 33 kg, and runs on 220 V with a power rating of 2,120 W.
