Overview
The Izzo Alex Duetto IV is the fourth generation of one of the original prosumer dual boiler espresso machines, carrying a legacy that helped establish the home dual boiler category. Izzo, a family-owned Italian manufacturer, has refined the Duetto over nearly two decades into a mature, thoroughly proven machine. The dual copper boilers — a 500ml brew boiler and a massive 1.5-liter steam boiler — provide exceptional thermal stability and endless steam capacity. Both boilers feature independent PID temperature control with digital displays, allowing precise management of brew and steam temperatures. The E61 group head is a timeless design known for its thermosyphon heating and signature manual lever, while the quiet rotary pump provides smooth, consistent extraction pressure. The pre-infusion system allows the puck to saturate at line pressure before the pump engages, enhancing extraction quality. The Duetto IV can be plumbed directly to a water line or operate from the 3.5-liter reservoir, and the built-in cup warmer accommodates multiple cups. The copper boilers give the Duetto its characteristic warm, round flavor profile that many Italian espresso traditionalists prefer. For those who value proven, reliable engineering from a genuine Italian manufacturer, the Alex Duetto IV is a dependable workhorse.
The Izzo Alex Duetto IV comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a dual boiler boiler system made of copper with a 500 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $2,900, the Izzo Alex Duetto IV is designed for dedicated prosumers who demand professional-grade equipment. The dual boiler design allows simultaneous brewing and steaming, making it ideal for milk-based drinks without any wait time.
In terms of build quality, the Izzo Alex Duetto IV is a substantial machine, weighing in at 27.0 kg, manufactured in Italy, drawing 1800W of power. With dimensions of 300 x 475 x 410 mm (W×D×H), make sure you have adequate counter space. It offers both reservoir and direct plumbing options for maximum flexibility.
