One press of a button, the rotary pump hums almost silently, and the first drop emerges – thick, honey-colored, with a crema that slowly closes. What you taste in the cup has a reason: the GS3 maintains such stable temperature that the first shot in the morning tastes just like the third in the afternoon.\u003c\/p\u003e\n\n\u003cp\u003eThe GS3 AV is a machine from La Marzocco's professional modular system, built in Florence – only compact enough for your kitchen. AV stands for Auto-Volumetric: you program your shot volumes, and a button press automatically stops the shot. We at Coffee Coaching Club are partners of La Marzocco and a coffee roastery in one – we know the machine inside and out and roast the beans that go with it.\u003c\/p\u003e\n\n\u003ch3\u003eWhat makes the GS3 special\u003c\/h3\u003e\n\n\u003cp\u003eThe heart of the GS3 is the saturated group head. With an E61 group head – the standard for many home machines – water circulates through a heavy metal head, which only truly heats evenly after a longer warm-up time. With the GS3, the group head is directly connected to the brew boiler and permanently surrounded by hot water. The water hits the coffee grounds at the set temperature – shot after shot, without fluctuation.\u003c\/p\u003e\n\n\u003cp\u003eCoffee contains over 800 aromatic compounds, and which of them end up in your cup depends on how consistently temperature and pressure penetrate the puck. A one or two-degree difference determines whether a shot becomes round and sweet or flat. In our roastery, we observe that saturated group heads deliver a more refined aromatic profile than E61 – that's our view, one of many.\u003c\/p\u003e\n\n\u003cp\u003eAdditionally, the dual boiler: separate boilers for brew water and steam, both PID controlled. You can brew espresso and steam milk simultaneously, without one function waiting for the other. The steam has enough reserve to make cappuccinos for several guests in a row without the pressure dropping.\u003c\/p\u003e\n\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\n\u003ctable class=\"ccc-compare-table\"\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMachine type\u003c\/td\u003e\n\n\u003ctd\u003eDual boiler with saturated group head\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eControl\u003c\/td\u003e\n\n\u003ctd\u003eAV (Auto-Volumetric) – programmable shot volumes, PID\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eBrew boiler \/ Steam boiler\u003c\/td\u003e\n\n\u003ctd\u003e1.5 L \/ 3.5 L\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003ePump\u003c\/td\u003e\n\n\u003ctd\u003eRotary pump (quiet, linear pressure build-up)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003ePortafilter\u003c\/td\u003e\n\n\u003ctd\u003e58 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eWater\u003c\/td\u003e\n\n\u003ctd\u003eTank or plumbed-in\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eApp control\u003c\/td\u003e\n\n\u003ctd\u003eLa Marzocco Home App compatible\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eCasing \/ Colors\u003c\/td\u003e\n\n\u003ctd\u003eStainless steel – Black, White, Silver\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eWeight\u003c\/td\u003e\n\n\u003ctd\u003eapprox. 34 kg\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eManufacture\u003c\/td\u003e\n\n\u003ctd\u003eFlorence, Italy\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e\n\n\u003ch3\u003eAV or MP\u003c\/h3\u003e\n\n\u003cp\u003eThis page is for the AV (Auto-Volumetric) version: you program shot volumes, a button press starts, and the machine stops automatically – good for repeatability and if multiple people use the machine.

There are very good machines for significantly less money. Those who choose a GS3 are looking for the saturated group head in their own kitchen – the thermal stability of a café machine, the mass, the presence on the counter. Those who want that usually know why. The GS3 is a decision, not a compromise.\u003c\/p\u003e\n\n\u003ch3\u003eWhat goes with it\u003c\/h3\u003e\n\n\u003cp\u003eThe grinder makes the biggest difference. Freshly ground coffee determines what arrives retro-nasally in the cup – pre-ground coffee loses in minutes what the bean has built up over months.
