Make excellent espresso with the Diletta Mio Espresso Machine. Tailored for energy efficiency without sacrificing in-cup quality, the Mio makes standout espresso thanks to its PID equipped single boiler, while a separate steam circuit offers easy work when milk drinks are a must. Quick access to temperature controls, shot times, and brew pressure lets you set up the Mio for bright single origins or traditional comfort blends alike. Milk drinks are managed differently; a second pump and heating element allow for simultaneous steaming without affecting your carefully-chosen brew parameters. The Mio also excels at efficiency, with a low power draw at idle (thanks to its tight PID temperature control, insulated boiler, and short water path), selectable steam circuit, and optional Eco mode that restricts power when not in use. Best of all, the Mio offers handmade Italian craftsmanship and excellent serviceability, ensuring it will help you make espresso you love for years to come.
