Gaggia Classic E24 Review: The Home Barista Classic Gets a Brass Boiler

The Gaggia Classic has been one of the most recognisable home espresso machines for decades.

The formula has always been relatively simple:

proper espresso hardware, traditional controls, strong steaming potential and very little automation.

The Gaggia Classic E24 keeps that philosophy but makes one particularly important change.

The boiler is now lead-free brass.

Gaggia has also increased its capacity, with the aim of improving temperature stability and delivering more consistent steam pressure for longer.

That's a much more meaningful upgrade than adding a touchscreen or another dozen drink presets.

But the Classic E24 remains unapologetically manual.

There's no grinder.

No automatic dosing.

No assisted tamping.

No automatic milk.

And certainly no button labelled “flat white”.

For the right person, that's exactly why it's so appealing.

Coffee Machine Reviews Verdict

Overall: 9.1/10

Best for: Coffee drinkers who want to learn traditional espresso properly.

Avoid if: You want the machine to make decisions for you.

Machine type: Manual espresso

Built-in grinder: No

Boiler: 120cc lead-free brass

Milk: Manual steam wand

Our verdict: The E24 improves the Classic in exactly the area enthusiasts wanted: thermal and steaming performance. It's still demanding, but that's part of the attraction.

What's New About the Gaggia Classic E24?

The major change is the boiler.

Previous Classic generations have used aluminium boiler designs.

The E24 introduces a 120cc CW510 lead-free brass brew boiler.

Why does that matter?

Brass has different thermal properties and the larger boiler stores more heat.

Gaggia says this improves:

• temperature stability;
• steam-pressure stability;
• steam duration.

Those are precisely the areas where we'd rather see Gaggia spending its engineering budget.

This isn't a machine that needs Netflix on the front.

It needs stable hot water and steam.

What Is the Gaggia Classic?

The Classic is essentially an entry point into traditional home espresso.

You're responsible for:

• grinding the beans;
• dosing;
• distributing;
• tamping;
• controlling extraction;
• steaming milk.

The machine provides the pressure, temperature and steam.

You provide the technique.

That's completely different from buying a De’Longhi Rivelia or JURA.

Do You Need a Grinder?

Yes.

We'd go further:

don't buy a Gaggia Classic E24 without budgeting for a proper espresso grinder.

The grinder isn't an optional accessory if you want to get the best from this machine.

Espresso requires extremely fine adjustments.

A small grind change can dramatically alter how quickly water passes through the coffee.

Spend your entire budget on the machine and use a cheap blade grinder and you've built the wrong setup.

Espresso Quality

This is where the Classic earns its reputation.

The E24 has considerably more espresso potential than its simple controls suggest.

Give it:

• freshly roasted beans;
• a capable grinder;
• an appropriate dose;
• careful puck preparation;
• some practice;

and you can produce genuinely excellent espresso.

But notice how many variables we just listed.

The Gaggia doesn't automatically correct your mistakes.

If your grind is wrong, your espresso will tell you.

If your puck preparation is poor, your espresso will tell you.

If you're looking for a machine that protects you from all of that, buy something else.

Is It Better Than Bean-to-Cup Espresso?

Potentially, yes.

Automatically?

Absolutely not.

A skilled user can exercise far greater control over extraction with the Classic than with a conventional bean-to-cup machine.

But the bean-to-cup owner can press a button while half asleep and receive a repeatable drink.

The Gaggia owner has to earn it.

That's the trade.

The Brass Boiler

The E24's brass boiler is arguably the strongest reason to choose it over an older Classic.

Gaggia lists its capacity at 120cc.

The increased thermal mass should help reduce temperature fluctuation and provide more sustained steaming compared with previous smaller boiler designs.

This doesn't turn the Classic into a commercial dual-boiler machine.

It's still a compact single-boiler home espresso machine.

But it's a sensible improvement.

Milk Steaming

Milk is completely manual.

You control:

• steam;
• wand position;
• aeration;
• vortex;
• temperature.

Initially, you'll probably make some dreadful milk.

That's normal.

Once you've learned the technique, you have considerably more control over texture than you get from most automatic milk carafes.

That makes the Classic particularly attractive for people who want to learn:

• microfoam;
• flat whites;
• latte;
• cappuccino;
• latte art.

Switching Between Espresso and Steam

Remember that this is a single-boiler machine.

You aren't simultaneously brewing espresso and steaming milk.

You'll switch the machine into steam mode and allow the boiler to reach the required steaming temperature.

That workflow is slower than a dual-boiler or sophisticated thermoblock machine.

For one or two drinks at home, that's manageable.

For six cappuccinos in succession, you'll notice the limitation.

Controls

The Classic remains refreshingly simple.

Physical rocker switches control the core functions.

There isn't a touchscreen asking who is drinking coffee today.

There isn't an app.

There aren't saved profiles.

There isn't a guided wizard.

For some people, this will feel old-fashioned.

For others, it's one of the best things about the machine.

Build Quality

The Classic has always sold partly on its substantial, traditional construction.

The E24 adds a premium stainless-steel filter holder alongside the new brass boiler.

This is a machine designed to feel more like a piece of coffee equipment than a smart kitchen appliance.

That distinction matters if you're planning to keep it for years.

Is the Gaggia Classic E24 Good for Beginners?

Yes and no.

Yes, if:

you want to learn.

The Classic forces you to understand what grind, dose, extraction and steaming actually do.

No, if:

you want good espresso immediately with minimal effort.

A Sage Bambino Plus, Barista Express Impress or Ninja Luxe Café provides considerably more assistance.

The Classic teaches by making you do the work.

Gaggia Classic E24 vs Sage Bambino Plus

This is one of the most useful comparisons.

Gaggia Classic E24

Better for:

• enthusiasts;
• traditional espresso;
• manual control;
• manual steaming;
• learning technique;
• long-term tinkering.

Sage Bambino Plus

Better for:

• beginners;
• small kitchens;
• fast heating;
• automatic milk;
• easier everyday use.

The Gaggia is the more traditional machine.

The Bambino Plus is the more approachable one.

Gaggia Classic E24 vs Barista Express Impress

The Sage includes:

• grinder;
• intelligent dosing;
• assisted tamping;
• pressure feedback.

The Gaggia includes none of those things.

That's not necessarily a criticism.

Pair the Gaggia with a better standalone grinder and it gives you a more modular setup.

The Sage gives you a much easier route into espresso.

Can You Upgrade the Gaggia Classic?

This is another reason the Classic has such a devoted following.

There's a substantial ecosystem around these machines.

Owners frequently explore different:

• baskets;
• portafilters;
• shower screens;
• steam accessories;
• temperature-control modifications;
• other espresso accessories.

Be sensible.

Modifications can have safety, warranty and reliability implications.

You don't need to modify a new E24 before you've even learned how to use it.

Cleaning and Maintenance

The relatively traditional design means routine maintenance is straightforward but hands-on.

Expect to:

• rinse the portafilter;
• clean baskets;
• wipe and purge the steam wand;
• clean the group area;
• empty the drip tray;
• backflush where appropriate according to guidance;
• descale according to water conditions and manufacturer instructions.

There's less hidden milk plumbing than on an automatic machine.

But you're responsible for maintaining the equipment yourself.

Who Should Buy the Gaggia Classic E24?

Buy it if:

• you want espresso to become a hobby;
• you already own or will buy a good grinder;
• you want manual milk control;
• you enjoy learning technique;
• you value traditional construction;
• you want a setup you can develop over time.

Who Shouldn't Buy It?

Look elsewhere if:

• you want one-touch coffee;
• you hate mess;
• you don't want to learn;
• you want automatic milk;
• you don't want a separate grinder;
• you regularly make lots of drinks back-to-back.

Is the Gaggia Classic E24 Worth It?

For enthusiasts, yes.

The move to a larger brass boiler addresses something that actually matters to espresso preparation rather than adding superficial technology.

But the Classic remains a specialist recommendation.

It's easy to see people online praising the machine and assume it's automatically the best espresso machine for everyone.

It isn't.

It's a machine that rewards effort.

That's very different.

Final Verdict

The Gaggia Classic E24 doesn't try to hide the process of making espresso.

It puts you in charge of it.

That's why it can simultaneously be one of the most rewarding machines on this site and one of the least suitable for somebody who simply wants coffee before work.

The new brass boiler makes the current generation particularly interesting.

Pair it with a strong grinder, good beans and a willingness to learn and you've got the foundation of a serious home espresso setup.
