Overview
The Quick Mill Aquila is a heat exchanger E61 machine that embodies the Quick Mill philosophy of straightforward engineering and exceptional reliability. The Aquila — named after the eagle constellation — features a 1.5-liter copper boiler with heat exchanger system and the classic E61 group head. The copper boiler provides excellent heat retention and strong steam performance, while the E61 group head delivers thermal stability and natural pre-infusion through its thermosiphon circuit. The Aquila uses a pressurestat for temperature control, which works well with the thermal buffering of the copper boiler and E61 thermal mass. The vibratory pump provides consistent 9-bar pressure, and the generous reservoir minimizes refill interruptions. Build quality is classic Quick Mill — solid construction with quality materials designed for long service life. The Aquila does not chase features — it focuses on doing the fundamentals exceptionally well. For the home barista who wants a reliable, well-built E61 heat exchanger machine that will produce excellent espresso for years without demanding constant attention, the Aquila is a trustworthy choice from one of Italy most enduring espresso machine manufacturers.
The Quick Mill Aquila comes equipped with pre-infusion for even extraction. It features a heat exchanger boiler system made of copper with a 1500 ml capacity. The vibratory pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $1,499, the Quick Mill Aquila is designed for serious home baristas who want café-quality espresso. The heat exchanger design provides steam-on-demand while maintaining brew temperature stability — a great middle ground between single and dual boiler machines.
In terms of build quality, the Quick Mill Aquila is a substantial machine, weighing in at 22.0 kg, manufactured in Italy, drawing 1200W of power. With dimensions of 290 x 440 x 400 mm (W×D×H), make sure you have adequate counter space. The built-in water reservoir holds 2500 ml, making it easy to set up anywhere in your kitchen.
