NSF-Rated For Commercial Use
La Marzocco’s GS3 Espresso Machine is designed for the passionate espresso enthusiast who knows the only way to be satisfied is to invest in one of the best machines available. The GS3 is pricey, but its commercial-grade features more than balance the cost: Dual stainless steel boilers, powerful steaming functionality, PID temperature control, volumetric pump and variable hot water temperature regulation to name a few.
Features and Functionality
Dual Stainless Steel Boilers – A 3.5 liter steam boiler produces strong, dry and sustained steam, easily producing latte microfoam. This is complemented by the separate 1.5 liter brew boiler, which allows for excellent temperature consistency and regulation for both operations.
Large Internal Reservoir – 3.5 liter reservoir loads from the bottom, resting behind the drip tray, and features an opening for easy refill without removing the entire unit.
Convertible Water Source – Use the internal reservoir or set the machine up to directly connect to your location’s plumbing.
Sophisticated PID Control – Tailoring your brew temperature to achieve the best extract is simple with this digital-displayed PID that utilizes multifunction keypads.
No Burn Wands – Double wall insulated stainless steel hot water and steam wands offer easier handling and cleaning.
Internal Volumetric Pump – Also known as a rotary vane pump, this quieter pump is designed to maintain a specific volume capacity that is consistently maintained.
Saturated Brew Group – Water is distributed evenly across the brew group, resulting in an more consistent pre-infusion and extraction rate, reducing the possibility of channeling.
Hot Water Tweaking – Easily select how much cold water you want incorporated into the hot water pulled from the boiler, tailoring your teas or Americanos to your preferred temperature.
Monster Drip Tray – If you don’t setup the draining kit, no worries — the huge capacity of the GS/3’s drip tray means you won’t have to empty it very often.
Pros
Temperature Control – With the PID interface, you can select your ideal brewing temperature based on the coffee you’re using.
Steam Power – The GS/3 makes tons of dry steam that quickly and easily creates silky microfoam.
Build Quality – The commercial-grade build quality makes this machine a must for your home or cafe.
Cons
Price – This is one of the most expensive machines that’s designed for home espresso. A good workman never blames his tools. You won’t regret it 🙂
Size – The GS/3’s large size takes up prime countertop real estate. If you’ve got it, flaunt it! Park that baby front and center.
How Does it Compare? 2017 Update! La Marzocco has made some recent changes to the GS/3 MP version. The new GS/3 MP sports a redesigned conical valve (a common repair point in earlier models), a new brew pressure manometer at the brew head, and a modified pump switch that allows for pre-infusion and manual pressure control when using the reservoir. Both AV and MP configurations now feature a new cool touch steam wand that replaces the teflon inner lining with a double wall stainless steel design.
