The Gaggia Classic Pro Evo used an aluminum boiler with an internal coating designed to reduce scale buildup and increase longevity. However, this coating proved problematic, flaking off and contaminating the steam and brew. As a result, Gaggia discontinued the machines with that coated boiler and now produces them with either a non-coated aluminum boiler or a brass boiler.
This video provides a detailed walkthrough and review of the Gaggia Classic E24 espresso machine. The speaker examines its features, components, and construction, highlighting its strengths and weaknesses. The video also discusses modifications and upgrades available for the machine.
The speaker recommends several modifications for the Gaggia Classic E24 to enhance its performance and aesthetics. These include a slimline drip tray for better fit under a scale, walnut-made portafilter holder and steam wand, and a backlight for improved visibility of the water tank level. He also suggests a PID, pressure gauge, and flow control for superior control over the brewing process. He recommends sourcing many of these modifications from Shades of Coffee, providing a link in the video description.
