After months of hands-on testing with the Gaggia Classic Pro, including the latest “Evo” and brass boiler “E24” versions, we’re sharing our comprehensive findings about these remarkable machines.
Our team’s experience with the Gaggia Classic spans decades – we’ve pulled thousands of shots on these machines and watched them grow from the 1991 original into today’s modern variants.
The Gaggia Classic has earned its place as the go-to espresso machine for serious home baristas. While the 2009 Philips acquisition briefly steered the Classic away from its roots, moving production away from Italy and making some questionable design choices, the brand eventually found its way back.
The turning point came in 2015 when Philips made the controversial decision to remove the 3-way solenoid valve. Fortunately, they soon recognised their misstep and handed control back to Gaggia Milano. The result? A return to form with the 2019 Gaggia Classic Pro, featuring Italian manufacturing, the reinstated solenoid valve, and a professional-grade steam wand.
Recent developments, including some challenges with the 2023 Evo Pro version (which we’ll detail below), have led to further refinements. The latest E24 model now sports a brass boiler, marking another evolution in this machine’s impressive journey.
We’ve thoroughly tested each iteration of the Gaggia Classic Pro, and we’ll break down the key differences to help you choose the right model for your needs.
This model builds on the solid foundation of the 2019 Pro, introducing a solid brass group head (replacing the chrome-plated version) and a robust stainless steel portafilter instead of chrome-plated brass.
While the internal wiring saw minor updates, the core machine remains unchanged. North American customers benefit from a 9-bar OPV, while European models maintain the traditional higher-pressure setup.
The most significant change – and subsequent challenge – was the introduction of a non-stick boiler coating. Gaggia implemented this to prevent potential galvanic corrosion between the uncoated brass group and aluminium boiler. However, some coating adhesion issues led to flaking, prompting quick action from the company.
For bargain hunters, this presents an opportunity – Gaggia Direct offers these at reduced prices. Our advice? The risk is minimal, as they’ll sort any issues promptly. Simply run water through the steam wand (tip removed) periodically to check for any coating particles.
This version keeps all the improvements of the 2023 Evo Pro but returns to the tried-and-tested uncoated aluminium boiler. If you’re comfortable with aluminium components, this discounted model from Gaggia Direct offers brilliant value without any coating concerns.
The newest iteration of the Classic Pro family introduces a brass boiler – a change that’s brought unexpected benefits. While this switch might have been influenced by public opinion about aluminium, the 30% larger boiler capacity (now over 100ml) addresses one of our few criticisms of earlier models. We’re currently putting this version through its paces, so watch this space for our detailed findings.
The Classic’s enduring success isn’t down to chance. When we repair and maintain these machines in our workshop, we’re constantly impressed by their commercial-grade construction. The predominant use of stainless steel, coupled with standard, readily available parts, makes them incredibly serviceable and durable.
This commercial-style build quality, at a remarkably competitive price point, sets it apart from typical domestic machines. Here’s what makes it special compared to cheaper alternatives:
The Classic truly stands as a benchmark in home espresso equipment.

After extensive testing in our coffee lab, we’ve found that the Gaggia Classic Pro (launched in the UK market in 2020 as the Classic Pro 2019) represents a brilliant return to form for this iconic brand.
What impressed us most was Gaggia’s bold decision to effectively hit the reset button. Rather than continuing down the path of questionable modifications, they went back to basics, taking inspiration from their pre-2009 Classic model—but with some genuinely useful modern improvements.
The most notable upgrade is the professional steam wand that comes standard. This is a massive win for coffee enthusiasts who previously had to faff about with installing a Rancilio Silvia wand modification. When we tested the steam wand, we found it delivers the precise control needed for creating silky microfoam.
Our technical assessment revealed other welcome returns to form: the restoration of the 3-way solenoid valve and the removal of unnecessary plastic components. The classic rocker switches are back too, though with one small caveat—the power button, while similar in appearance to the original, incorporates modern energy-saving auto-shutdown features. This is hardly a compromise, especially compared to the 2015 model’s problematic shot button that had sticking issues.
The one point of discussion among our testing team was the modified Over-Pressure Valve (OPV). While it’s factory-set at 13-14 bars and isn’t adjustable out of the box, we’ve found an elegant solution: the OPV modification kit from Shades of Coffee. For about £10 and a few minutes of work, you can adjust the pressure to either 9 or 6 bars.
This high factory pressure setting reflects Gaggia’s clever market positioning. Through our testing, we’ve identified two distinct user groups:
Our analysis suggests that the higher pressure setting better serves the first group, which likely makes up around 80% of users. The machine wouldn’t perform as effectively for casual users at 9 bars with pre-ground coffee.
We’re particularly pleased with Gaggia’s decision to offer various colour options beyond the traditional stainless steel. Speaking from experience with our video reviews, this makes our job much easier when filming!
However, we did notice one potential contradiction in Gaggia’s approach. While they’ve maintained features catering to both market segments, the professional steam wand might prove intimidating for casual users. Though we can assure you it just takes a bit of practice to master, we wonder if some potential buyers might find it off-putting.
In our professional opinion, Gaggia might have better served both markets with two distinct models: a home barista version featuring the pro steam wand and adjustable OPV, and a consumer version with a panarello wand and standard OPV settings for pre-ground coffee and ESE pods.
For those interested in the 2019 Classic, be aware that new units are increasingly scarce—you’ll likely need to explore the second-hand market.
At Caffeinated Gear, we’ve thoroughly tested the latest Gaggia Classic E24, comparing it side-by-side with previous models. Our hands-on experience reveals significant improvements that could make a real difference to your morning brew.
The move to a solid brass group (specifically CW510L lead-free) from chrome-plated brass marks a significant shift in manufacturing philosophy. We appreciate Gaggia’s commitment to both environmental responsibility and staff wellbeing by eliminating electroplating processes. This change, introduced in the Evo 2023 version, continues in the E24.
The boiler’s journey to its current form tells an interesting story. Our testing shows the new brass boiler brings notable improvements:
The switch to brass wasn’t just a reaction to previous challenges – it’s a genuine upgrade. While earlier versions experimented with coated aluminium boilers, the new brass construction offers better performance without any coating concerns.
The solid stainless steel dispersion plate represents a significant upgrade from the lightweight aluminium versions seen in earlier models. We’ve found this robust component delivers more consistent extraction and should last the lifetime of the machine.
Gone are the days of chrome-plated brass portafilters with their susceptibility to marking and potential plating issues. The E24 features a solid stainless steel portafilter that matches the machine’s build quality. During our testing, we noticed improved durability and resistance to daily wear and tear.
We’re currently testing the new E24 model extensively, and we’ll update this review with our detailed findings on how these changes affect real-world brewing performance.
Our technical specialists have noted significant improvements in the machine’s assembly process.
While this might seem like a behind-the-scenes detail, we’ve found it translates into simpler maintenance procedures for home users.
As coffee equipment experts who regularly service these machines, we can confirm that the newer models feature more accessible components and a more straightforward internal layout.
The current home espresso market offers an impressive range of choices – though we understand this can feel overwhelming when you’re making a decision.
Our team has spent countless hours testing various machines in this category, and we can help you navigate these waters.
Let’s be honest – while the Gaggia Classic enjoys an almost legendary status among coffee enthusiasts, it might not be the ideal choice for everyone seeking their first single boiler espresso machine.
In our extensive testing at Caffeinated Gear, we’ve discovered that the “best” machine truly depends on your specific needs and preferences.
After all, the Gaggia Classic’s primary strength lies in its name and heritage.
For those who’ve spent years mastering its quirks and nuances, the thought of switching to a different machine might feel like learning a new language.
The Classic’s second major strength? It’s arguably the most customisable single boiler espresso machine on the market.
Now, some coffee enthusiasts might question why anyone would want a machine that needs modifications. But we’ve found that for many of our readers, the ability to tinker and personalise their equipment is part of the joy of home espresso making.
If you’re seeking a machine you can truly make your own through modifications, the Classic stands alone in this category.
However, if temperature stability and precision straight out of the box top your priority list, we’ve got an interesting alternative that costs less than the Classic E24:
During our testing, we found that the Anna PID deserves serious consideration for anyone seeking a sub-£500 single boiler machine with excellent temperature control without requiring modifications.
Its impressive features include:
We did notice two minor drawbacks: the unusual 57mm portafilter size (which limits accessory options) and the rather disappointing stock tamper. You’ll want to budget an extra £30-40 for a proper Lelit tamper.
The steam knob could use some refinement, and the case edges are slightly sharper than we’d prefer, but these are minor quibbles given the exceptional value this machine offers.
For those willing to stretch their budget, we’ve been particularly impressed with the Lelit Victoria. It’s priced similarly to a fully modded Gaggia Classic Pro and offers compelling features that rival even the Profitec Go, despite being £100 less.
For a comprehensive analysis of the entire Lelit range, check out our detailed review:
The future of this iconic machine sparks interesting discussions in our team meetings.
We’ve had hands-on experience with commercial Gaggia machines like the La Dea, a stunning E61 group heat exchanger model. It’s puzzling why Gaggia hasn’t adapted their commercial designs for home users, similar to how La Marzocco created the Linea Mini.
Take the Gaggia Reale (which sits proudly in our testing studio) – its programmable profiles and robust build quality would make for an incredible domestic machine if scaled down appropriately.
The answer depends entirely on your priorities.
If it aligns perfectly with your requirements and outperforms other machines in its price range, then absolutely – especially considering it’s one of the most affordable single boiler espresso machines available.
Our experience shows that Classics maintain excellent resale value. In fact, vintage models often sell for multiple times their original price.
For those still weighing their options, we recommend creating a checklist of must-have features. Compare the Classic against similarly priced competitors like:
If your budget allows, consider including the Lelit Victoria and Profitec Go in your comparison.
When selecting a grinder for your Classic machine, your choice should align with your brewing style and bean preferences.
For those using standard supermarket beans with pressurised baskets, most entry-level grinders will serve you well.
The Gaggia MD15, for instance, handles these beans perfectly adequately.
However, the landscape changes dramatically when you venture into fresh-roasted beans and traditional baskets.
Here, precision becomes crucial, and you’ll need a proper espresso-capable grinder.
In our extensive testing, we’ve found that the minimum requirements for quality espresso start with either the Sage Dose Control Pro, Smart Grinder Pro, or the impressive Baratza Encore ESP.
While the Gaggia MD15 can work with the included shims (a straightforward modification), its 15 adjustment steps are quite broad, limiting your ability to achieve that perfect grind setting.
We’re particularly excited about Gaggia Direct’s current bundle offer: the Classic E24 paired with their new MDF55 (essentially Gaggia’s version of the highly regarded Eureka Mignon Specialita).

Before we wrap up our grinder discussion, we’d like to highlight an interesting budget alternative to the Classic that’s caught our attention.
Let’s be crystal clear: the new Espresso isn’t trying to be a Classic.
At less than half the price, it naturally can’t match the Classic’s build quality or espresso-making capabilities.
However, what truly impressed us during our testing was how it outperforms every other machine in its price bracket.
For coffee enthusiasts working with a tighter budget, this machine offers remarkable value.
We were particularly surprised by its inclusion of a PID temperature controller—a feature virtually unheard of at this price point.
This means you’ll enjoy better temperature stability than many pricier machines, including the unmodified Classic.
Another pleasant surprise is the standard portafilter design.
While it comes with pressurised baskets, you only need to swap in a standard basket to unlock its full potential—no need for a complete portafilter replacement.
The thermoblock heating system, while different from the Classic’s boiler, offers consistent steam power—a genuine advantage for milk-based drinks.
We love the versatile steam wand design: a panarello attachment for beginners that reveals a professional-style single-tip wand underneath when removed.
That said, there are some compromises.
The absence of a 3-way solenoid valve (common at this price point) means water hits the coffee puck with full force.
However, we’ve found a brilliant workaround: placing an inexpensive puck filter (similar to an AeroPress filter) on top of your grounds significantly improves extraction quality.
These filters are both cost-effective and reusable for several shots.
The machine’s Italian manufacturing is impressive at this price point.
While it might not match the Classic’s legendary durability, it offers remarkable value for budget-conscious buyers.
Our recent discovery that it’s compatible with the Gaggia Classic OPV Mod from Shades of Coffee makes it an even more compelling option for those looking to enhance their coffee journey without breaking the bank.

The sub-£500 market is brimming with excellent options, and we frequently field questions about the Gaggia Classic versus the Sage Bambino Plus. Our honest answer? It genuinely depends on your preferences and brewing style. These machines cater to distinctly different types of coffee enthusiasts.
If you’re drawn to the charm of traditional espresso craftsmanship—someone who relishes the journey of mastering their machine, enjoys tinkering with modifications, and appreciates the ability to maintain the equipment yourself—then the Gaggia Classic Pro deserves pride of place in your kitchen. Its robust build quality means it could serve as your faithful brewing companion for decades to come.
However, if you prioritise modern convenience and the thought of dismantling your espresso machine makes you wince, the Sage Bambino Plus might better suit your coffee-making style. It offers a more streamlined approach to achieving excellent espresso.
