  • 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.
