ACS Vesuvius Espresso Machine

Unlike standard machines that use a fixed pump pressure, the Vesuvius allows you to program custom extraction curves across seven distinct control points. This gives you granular control over how water hits the coffee puck, enabling you to highlight specific flavor notes or correct for roast profiles that are difficult to manage on traditional machines.

The brushless gear pump with magnetic drive is exceptionally quiet and offers precise, consistent flow control. Because it is decoupled from the motor, it eliminates the mechanical vibrations often found in standard rotary pumps, contributing to a more stable and reliable extraction process.

While many prosumer machines use a 58mm standard, the Vesuvius utilizes a 54mm portafilter. This design choice is intentional, as it creates a deeper coffee puck that can offer better heat retention and extraction efficiency, though it does mean you will need to ensure your accessories, like tampers and baskets, are sized specifically for 54mm equipment.

The interface is designed to simplify complex adjustments rather than complicate them. While the machine is built for advanced users who want to manipulate pressure and temperature, the touchscreen makes navigating these settings intuitive, allowing you to save profiles and monitor your shots without needing to memorize complicated button sequences.

This machine is designed for 115V operation and requires a standard household outlet. It draws 2500 watts, so it is best to ensure it is plugged into a dedicated circuit to maintain consistent performance and avoid tripping your breaker.

The Vesuvius is a substantial machine, measuring 36.8 cm wide by 49.5 cm deep and 41.5 cm high. Given its weight of 36 kg, you will need a sturdy, stable surface that can comfortably support its footprint and heft.
