Auto-Volumetric Precision for Perfect Shots

The GS3 AV uses an advanced auto-volumetric system that allows you to program the exact amount of water used for each espresso shot. Once set, the machine repeats the same recipe every time, ensuring consistent flavor and extraction. This makes it ideal for home baristas who value repeatability and accuracy.

Dual Boiler System with PID Control

Equipped with separate brew and steam boilers, the GS3 AV allows simultaneous brewing and steaming without temperature drop. The PID system enables precise temperature adjustment in small increments, giving you full control over extraction and ensuring stable results with every cup.

Commercial Build Quality and Steam Power

The GS3 AV is built using commercial-grade components designed or manufactured by La Marzocco. Its dedicated 3.5-liter steam boiler delivers strong, dry steam for smooth milk texturing, even when preparing multiple drinks back to back. The insulated no-burn steam wand adds safety and comfort during use.

Designed for Serious Home Baristas

With a saturated brew group, rotary pump, and stainless steel construction throughout, the GS3 AV is built for users who demand professional performance at home. While it requires adequate counter space, it rewards with reliability, durability, and unmatched espresso quality.

AV vs MP Comparison

Auto-Volumetric (AV) Model

The AV model is focused on precision and consistency. You program the desired shot volume on the control panel, and the machine uses an electronic system to deliver that exact amount each time. This makes it perfect for users who want repeatable results with minimal adjustments shot after shot. The AV is ideal if consistency and ease of use are your priorities.

Manual Paddle (MP) Model

The MP model replaces auto dosing with a manual paddle that gives you direct control over pressure throughout the extraction. This allows for pressure profiling — changing pressure at different points in the shot to influence flavor and body. Baristas who enjoy experimenting with extraction dynamics and tailoring each shot may prefer the MP version.

Key Differences

• Dosing Control
  AV: Automatic and repeatable volume dosing
  MP: Manual pressure control with user-driven extraction
• Consistency
  AV: Highly consistent shot to shot
  MP: Variable results based on technique
• Pressure Profiling
  AV: Not supported
  MP: Supported through manual paddle
• User Experience
  AV: Easier for routine use
  MP: More hands-on and customizable
