La Marzocco GS3 AV

The same thermal engineering that powers world-class cafes. On your counter.

The GS3 AV brings La Marzocco's saturated group head and dual-boiler architecture into a compact 110V frame. You get the thermal stability that professional baristas depend on — consistent temperature, consistent pressure, consistent results — without needing a commercial buildout. **Call for Leads Times! Usually 2 - 3 weeks**

Why It Costs What It Costs


What You Are Paying For

Saturated group head eliminates temperature swings

Brew vs. Steam Compromise

Independent dual boilers run simultaneously

Inconsistent Shots

Advanced thermal stability for repeatable extraction

Installation Hassle

Compact 110V design fits home espresso bars

How It Works


The GS3 AV uses a saturated group head — the same technology in La Marzocco's commercial machines — to maintain water temperature from boiler to puck with minimal loss. Two independent boilers let you pull espresso shots and steam milk at the same time without either system stealing heat from the other. The automatic volumetric dosing measures your shot for you, so once you dial in a recipe, the machine repeats it. All of this runs on standard 110V power in a footprint designed for home counters.

Key Specifications


Saturated Group Head

Water temperature stays locked from boiler to portafilter. No cold spots, no thermal drift between shots. The same technology behind the world's best cafes.

Dual Boiler System

Separate boilers for brewing and steaming operate independently. Pull a shot and texture milk simultaneously without any temperature compromise. No waiting, no trade-offs.

Volumetric Dosing

Program your shot volume once and the machine delivers that exact amount every time you press the button. Consistency on autopilot.

110V / Compact

Runs on a standard home outlet. The compact footprint fits into your espresso bar without requiring a commercial kitchen setup. Professional performance, residential power.

Thermal Stability

Advanced temperature management keeps your brew water precise across multiple back-to-back shots. Your tenth shot tastes like your first.

The Bottom Line

This is not an upgrade from your current machine. It is a different category entirely.

The GS3 AV is built for the person who has outgrown prosumer machines and wants commercial-grade thermal engineering without the commercial footprint. If you are pulling shots for yourself and a few guests and you want every single one to be identical, this is the machine that delivers that.

Is This the Right Machine


Made For

You have outgrown your current setup and want cafe-level consistency at home. You value thermal stability above all else and want a machine that repeats your recipe without drift. You appreciate volumetric dosing and the ability to brew and steam simultaneously.

Not For

You prefer full manual control over every variable in your shot — the MP model may be a better fit. You are looking for a budget-friendly entry into espresso. Or you need high-volume throughput for a busy commercial environment.

Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

I've been pulling back-to-back shots for a dinner party and the dual-boiler system never faltered once. It's a huge step up from my old machine.

Eli ★★★★★

The saturated group head keeps the temperature rock steady from shot to shot, which is a game-changer for dialing in different beans. After two weeks of daily use, I’m pulling consistently better espresso than my local café ever did.

Daniel I. ★★★★★

The saturated group head keeps the temperature rock steady from shot to shot, even when I'm pulling back-to-back lattes. The dual-boiler design means I can steam milk immediately without waiting, which makes morning workflow feel almost professional.
