The Gaggia Classic Evo Pro E24 is a deliberately simple portafilter machine. It does without PID, a display, and extensive automation, focusing instead on a classic single-boiler design with a brass boiler, 58-mm portafilter, and 3-way solenoid valve.
Especially in 2026, this kind of reduction can be appealing: Anyone who truly wants to learn espresso gets a platform where grind size, dose, and puck prep remain visibly decisive.
Brass Boiler and Brass Group
The current E24 generation uses brass at its thermal core. Brass stores heat well and is a proven material in espresso machine construction. However, actual temperature control remains simpler than with a PID machine.
58-mm Portafilter
The professional diameter opens up a huge range of accessories. Precision baskets, tampers, bottomless portafilters, and puck-prep tools are readily available.
3-Way Solenoid Valve
After the shot, pressure is released from the brew group. This ensures a cleaner workflow and a drier puck.
No PID: Problem or Learning Opportunity?
Without a freely adjustable PID, you need to become more familiar with the machine's thermal behavior. For some, this is a disadvantage; for others, that is precisely part of the appeal of a simple Classic.
Anyone who wants to control the temperature of different light roasts with great precision will find a PID solution more convenient.
Espresso Basics
The E24 rewards solid basics: a good grinder, a consistent dose, even distribution, proper tamping, and an appropriate coffee-to-beverage ratio. Anyone who learns these fundamentals will be able to use almost any machine better later on.
Steam Wand
The stainless steel steam wand makes cappuccinos and flat whites possible. As a single-boiler machine, it has to switch to steam temperature after brewing espresso. For individual milk drinks, this is quite manageable; for several in a row, it is less convenient.
Modding Potential
The Classic family has traditionally been popular with users who like to modify or optimize their machines themselves. Whether this makes sense depends on technical skill and warranty considerations. Not every upgrade is automatically necessary.
E24 or Classic UP?
UP for PID, pressure gauge, pre-infusion, and display from the factory. E24 for deliberately reduced technology and potentially making your own modifications.
E24 or Profitec GO 2.0?
The GO is equipped with considerably more modern features and offers PID/OLED. The Gaggia remains the simpler learning and modding platform.
Which Grinder?
A good grinder is especially important with the E24. The machine itself cannot compensate for inconsistent grinding. Therefore, invest in grind quality first rather than decorative accessories.
Water and Maintenance
Suitable water protects the brass boiler. Backflushing, cleaning the shower screen, degreasing the portafilter, and maintaining the steam wand are all part of the routine.
Strengths
- simple, understandable technology,
- brass boiler and brass group,
- 58-mm standard,
- 3-way solenoid valve,
- large accessory and community ecosystem.
Potential Limitations
- no PID from the factory,
- espresso and steam one after the other,
- more manual understanding of temperature required,
- less convenient than modern machines.
Who Is the E24 Suitable For?
For beginners and purists who genuinely want to learn espresso, appreciate 58-mm accessories, and deliberately do not need extensive electronics.
Frequently Asked Questions
Is the E24 only for beginners?
No. Experienced users also appreciate simple, direct machines. It offers less convenience, but not automatically less potential.
Can I add a PID later?
Modding solutions exist for the Classic family. However, modifications should be carried out safely from a technical perspective and with due regard for warranty and electrical safety.
Can it make several cappuccinos?
Yes, but because of the single-boiler principle, there is more waiting time than with a dual-boiler or heat-exchanger machine.
Conclusion
The E24 is appealing if you are looking for an honest mechanical learning platform. It forces you to master the espresso basics - and in the long term, that can be more valuable than a long feature list.
