Overview
The De'Longhi La Specialista Opera EC9155 stands as the flagship of De'Longhi's semi-automatic lineup, combining Italian design philosophy with smart brewing technology. The integrated conical burr grinder with sensor grinding technology measures bean density and adjusts grind time to deliver a precise dose every time. Smart Tamping applies exactly 20kg of consistent pressure — eliminating a common source of shot-to-shot variation. The machine features De'Longhi's advanced active temperature control system with three brewing temperature options to match roast profiles. An automatic milk frothing system with LatteCrema technology creates dense, silky microfoam at the touch of a button, though a manual wand is also available for hands-on texturing. The Opera introduces recipe customization through a color LCD screen, allowing users to save espresso strength, milk volume, and temperature preferences. Pre-infusion soaks the coffee puck before full pressure extraction for improved flavor clarity. Its premium metal and chrome finish brings genuine Italian style to any kitchen.
The De'Longhi La Specialista Opera EC9155 comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a thermoblock boiler system made of stainless steel. The vibratory pump delivers 19.0 bars of pressure for optimal extraction.
Priced at $1,099, the De'Longhi La Specialista Opera EC9155 is designed for serious home baristas who want café-quality espresso. As a semi-automatic machine, it gives you control over the brewing process while handling pressure and temperature automatically.
In terms of build quality, the De'Longhi La Specialista Opera EC9155 is a substantial machine, weighing in at 13.5 kg, manufactured in Italy, drawing 1450W of power. With dimensions of 350 x 400 x 400 mm (W×D×H), make sure you have adequate counter space. The built-in water reservoir holds 2000 ml, making it easy to set up anywhere in your kitchen.
