Dual-boiler espresso machines compared – the ultimate espresso machine test

We tested 12 dual-boiler espresso machines side by side over the past weeks and months. This test series was the most extensive we've ever done. Each machine was discussed in its own video. We addressed the most important characteristics, worked out differences, strengths, and weaknesses.

This text is a comparison of all machines. It was published alongside our detailed test and comparison video of all dual-boiler espresso machines.

The following machines were tested: Rocket Appartamento, Lelit Mara X, ECM Manufacture Mechanika V Slim, Profitec Pro 500, Bezzera BZ10, Rocket Mozzafiato Cronometro R, Quick Mill Rubino, ACM Homey, Quick Mill Andreja Premium PID, Elba 1 969.coffee, Bezzera Magica, Xenia Espresso

After testing the 12 dual-boilers, we tested additional dual-boilers. You can find a complete list of all tested dual-boilers at the very bottom of this page.

The linked video is intended as a supplement to the article. It provides visual material on individual topics in particular. We've set chapter markers to make it easier to find specific information.

As a coffee maker, we understand ourselves as a coffee school that supports knowledge transfer and exchange in the coffee market. We operate a coffee farm in Nicaragua, a roastery in Basel, and two cafés, and share the applied knowledge in our courses, articles, and videos.

What did we test in the espresso machines?

With this test report, we go even further. In addition to the external build quality and finish, we tested the milk frothing ability of each machine. The espresso machine test provides information about the power consumption of the dual-boilers and shows the temperature constancy during espresso extraction. We show the temperature for each machine from the start of espresso extraction to the endpoint. The temperature and constancy during brewing is crucial for coffee quality. Depending on the intended use, an espresso machine should be consistent across multiple extractions, meaning the first, second, and third espresso. This is especially important if the machine is to be used in a larger household, shared apartment, or at a party. We call this attribute "catering" or "shared apartment" capability.

The heat-up time of dual-boilers plays an important role not only for early risers. We have bad news in advance. The heat-up time of all machines doesn't differ so significantly that we have a clear test winner. For all 12 espresso machines, we recommend starting the device 25 minutes before the first extraction. Only then are the machines really well heated through, and some machines even need a bit longer.

We used this temperature sensor to measure the brewing temperature in the portafilter. Through a small valve at the bottom, water is released so that the resistance corresponds to an espresso extraction.

Why is there no clear dual-boiler test winner?

While testing, experimenting with, and getting to know the twelve espresso machines in depth, it became clear to us that it wouldn't be right to declare a ranking or test winner. The qualities of the machines are too different, the strengths too varied, and the possible uses differ as well. The tests were conducted mainly by Michel Aeschbacher and me, Benjamin Hohlmann. And even we couldn't definitively agree on which machine would be the test winner for each of us.

Michel values a lot of power when steaming milk, and the external finish of the machine and high-quality materials play a major role. For Benjamin, temperature constancy across 5 extractions is central, so the espresso machine can also be used well during meetings. And we haven't even talked about price-to-performance yet.

In short, we decided against an absolute ranking or adding a grade or points per category. Instead, we highlight which espresso machines perform best in which category. Based on your own needs, you can then decide which machine is best for you. Sorry we can't make the decision for you.

If there were an espresso machine that really rocks in all categories, we wouldn't hesitate to declare it as such. Unfortunately, there isn't one. Instead, there are only partial-category test winners (and losers), Michel's favorites, Benjamin's favorites, and the best value-for-money winner. Enjoy reading.

Build quality and external finish

You can argue about aesthetics and external finish. However, four machines stand out in our test. A bright spot – also thanks to beautiful finishing with wooden handles and in black – is the Xenia. The Xenia espresso machine can be modularly configured, which means it not only takes on the desired look but also the expansion design. Upon choice, the Xenia comes with one or two portafilters, in wood or classic or even naked. Each modularity costs separately – but you also don't get overwhelmed with unnecessary tools and gadgets. If you're looking for sharp edges on the Xenia, you're out of luck.

Xenia Espresso in side view

The Rocket Mozzafiato Cronometro R breaks the cost structure at +2000 euros/2400 CHF, way above our ranking. Accordingly, it flaunts its materials. The side panels of solid aluminum are 8 mm thick and contribute to the premium feel of the Mozzafiato. The overall build quality is good, and there are only a few sharp edges. The sturdy feet provide stability, and the cold touch steam wand rounds out the machine. A built-in clock is a nice additional feature. The Quick Mill Andreja Premium PID is also among the better-built machines. You can tell with it, as with the previously mentioned ones, that part of the higher purchase price goes into clean edges and thoughtful finishing.

The Lelit Mara X is among the cheapest machines in the entire test. All the more pleasing that it doesn't cut corners on external finish. The machine is just 22 cm wide with a depth of 41 cm. Anyone looking for a powerfully designed espresso machine will favor the Bezzera Magica or Rocket Mozzafiato. The Lelit Mara X is different. It has rounded corners where other machines are angular. It's as quiet as a purring kitten, while the Rocket Appartamento next to it feels like a tractor starting up. But in terms of external finish quality, the Mara plays in the top tier. The side walls of the Mara are noticeably thinner than, for example, the walls of a Quickmill Rubino – they feel somewhat metallic when tapped. This doesn't detract from the positive external appearance.

Solid exterior comes from the Profitec Pro 500, the Quick Mill Rubino, Bezzera Magica, Rocket Appartamento (embarrassing plastic railing – that's a cheek!), Elba, and ECM Mechanika Slim.

The two cheaper machines, the ACM Homey and BZ10, show their price point in appearance and feel. Here, many edges were simply spared, and not all metal was cleanly finished. You can get annoyed about it or let it go. Because what remains is: although there are sharp spots, both machines are still suitable for brewing good espresso. We think: rather that than the opposite.

Water tank – a solitary leader

We probably would have skipped this chapter if there weren't such a clear leader. The Xenia espresso machine leaves all other dual-boilers far behind in terms of water tank flexibility. You could also say that here, the developers of the machine, Holger Dreißig, is the only one who took the water tank seriously and sought smart solutions.

Freestanding espresso machines have no problem with refillability. But there are settings where a water tank cannot be removed from the top and can only be filled with difficulty from a pitcher. And pitcher filling is problematic anyway because it always carries the risk of putting the espresso machine underwater.

The water tank can be removed from the side on the Xenia. Very practical.

The Xenia offers – as an optional configuration variant – a side insert. The water tank can be removed from the machine to the left or right and filled that way. This is very practical in a cramped kitchen or a narrow usage situation like a camper van.

By the way, the insert variant is also practical because the cups sitting on the machine don't obstruct it. Good solutions for filling or removing from the top are provided by the Bezzera Magica, Profitec Pro 500, and the ECM Mechanika Slim. The cover with cups can be removed from the railing. Many other machines offer reduced space for cups and have a cover attached.

The ACM Homey offers the most unpleasant water tank removal (Video 11:25). Since there's no handle attached and the slot next to the water tank is too small to reach into, removing the tank is a hassle. The water tank removal of the Elba 969 also belongs to the less well-thought-out variants. First, all cups must be covered, then a plastic grate, and finally a lid must be removed. The handles of the water tank are inadequate, so here too follows the finger-water canister hassle.

Supplied tamper

A portafilter is good when it closes flush with the rim of the basket and the metal base sinks so deep that you can feel the rim of the basket with the flush base using your fingers. The tamper of the Lelit Mara X does this best. The tamper resembles some professional tampers and with a circumference of 58.5 mm is the ideal size. Clever is that only the lowest ring has exactly this diameter. This means the tamper closes cleanly with the basket wall at the pressure surface. At the same time, the tamper doesn't sit so tightly that a vacuum forms when pulling it out. Many flush tampers suck up the perfectly tamped grounds back up and create potential channeling spots.

Both Quick Mill models also come with a wooden tamper. The standard size of 58 mm leaves too much space to the rim here. Too bad, the base itself has good thickness and helps with even tamping.

The tamper of the ECM Mechanika Slim and Profitec Pro 500 pleases in terms of workmanship and sits almost perfectly in the portafilter. It fits more flush than the Rocket and Quick Mill tampers. The thickness of the tamper base is somewhat less, which means the tamper sinks into the basket during tamping. This makes it more difficult to guide the tamper straight.

The two Rocket models each come with an aluminum tamper. The distance to the basket rim is too large. Handling and aesthetics are certainly a matter of taste. For larger hands, the tamper is too small. The upper pressure point has a straight edge in contrast to the other tampers. Less pleasant – but certainly not a deal-breaker. The tamper next to the Rocket Appartamento feels appropriate. With the Rocket Mozzafiato in the top price segment of portafilters, a higher-quality tamper would have made a good impression.

The other espresso machines are supplied without a tamper or without anything worthy of that name. Many machines come with a plastic alibi tamper in their scope of delivery. However, this is a bad joke next to a high-quality dual-boiler machine. With the Xenia, purchasing a tamper is optionally available. In our view, a sensible choice.

A portafilter manufacturer doesn't have to be a tamper manufacturer. But if they supply a tamper, then please a decent one. Tampers are often collector's items and are bought separately anyway. There are many great tampers from small manufacturers, for example from Tidaka, Hauck, Prorista.

Portafilters of the espresso machines

Portafilters and baskets are important tools for the brewing process. They differ in handling, tamping ability, and also in the quality of the baskets. In many videos, we've discussed that a good portafilter positions the outlets away from the espresso machine. The main reason is that only then can you tamp at the table edge, which is the best option in everyday life. It's quick, clean, and the portafilter doesn't have to be awkwardly threaded into a tamper stand, potentially loosening the grounds again.

With the variant on the left, you quickly slip when tamping and destroy the puck.

Our perspective is "gastronomically" oriented. We've built tamper stations in coffee bars, but ultimately the barista always tamped at the edge of the bar on a tamping mat. This is always possible with gastro machines because the outlets are positioned accordingly.

The outlets of the portafilters of the following machines make tamping easier.

• ECM Mechanika Slim. That said, it's unfortunate that the outlet is very wide, causing the espresso to flicker as it flows and run from left to right. This has no taste impact, but sometimes looks like channeling and doesn't provide nice photos. 😊
• The Xenia Espresso tamper is sleek – we got a great wooden finish here. You pay extra for that, but it cuts quite a figure. The outlets are positioned in our desired direction, but unfortunately just as wide as the ECM Mechanika Slim, leading to the described flickering effect.
• One of the nicest tampers in the field comes with the Profitec Pro 500. "Installed the right way", pointed outlets, and it sits well in your hand.
• Similarly, the portafilter of the Elba.969 and ACM Homey are appealing. Both have matte portafilters that sit well in the hand.

"Too futuristic" says Michel. "Clever" says Benjamin. The portafilter of the Lelit Mara X

The portafilter of the Lelit Mara X breaks out of the classical portafilter framework. The espresso is released towards the back and then flows forward and becomes visible. Michel and my opinions differ here. Michel finds the portafilter "too futuristic". I like that Lelit was creative for once and offers new solutions. It looks great how the espresso flows forward and becomes visible. While you can't tamp the Lelit portafilter at the table edge either, since the outlets don't rest on the ground, they don't get dirty and carry coffee particles that later end up in the espresso. This is one of our main arguments against tamping with standing tampers. Moreover, classical portafilters are angled in the process, making it difficult to tamp straight. The Lelit portafilter, however, stands straight – so this problem doesn't exist.

The portafilter outlets of the other machines are twisted, making tamping more difficult. Otherwise they are "classical", though the portafilter of the Bezzera Magica deviates somewhat in shape.

The twisted portafilters are directly related to the size of the drip trays. The further a drip tray extends from the espresso machine, or the closer the brewing group sits to the body of the machine, the less danger there is of water dripping onto the table surface during rinsing and extraction. In addition to the BZ10, the Rocket Appartamento and Bezzera Magica drip water on the table surface when rinsing.

Noise level of espresso machines

Does the noise level of an espresso machine play a big role? Not for the quality of the espresso. But whoever has already skipped espresso in the morning because the rest of the house is still sleeping knows how interesting a quiet espresso machine can be. That said, almost every espresso grinder is louder. So the noise level of the espresso machine may be less relevant. For some, the Rocket Appartamento, which leads the noise field at 83 decibels, might even sound good. Following the motto: even if I take off on my motorcycle, I want the whole village to know about it.

The other values:

• Quick Mill Andreja: 75 – 78
• Quick Mill Rubino: 79 – 80
• ECM Manufacture Mechanika V Slim: 79 – 81
• Rocket Mozzafiatto Cronometro R: 68 – 70
• Profitec Pro 500: 78 – 80
• Xenia Espresso: 75 – 77
• Bezzera Magica: 78 – 80
• Elba 1, 969.coffee: 78
• Bezzera BZ 10: 75 – 77
• ACM Homey: 79 – 80
• Lelit Mara X: 71

For the record: we measured the noise level quite amateurishly with a cell phone, keeping the same distance. Don't hold us to the decibel figure. The values still give you an orientation. For all sound-sensitive folks: here's the file to listen to yourself.

Power consumption and energy efficiency

As with all electrical devices, with espresso machines the actual power consumption can barely be read from the power input specification. For the Lelit Mara X, for example, it's 1400 W, and for the Rocket Appartamento 1200 W. However, these values indicate consumption at full power. We were interested in how this looks over several operating hours and what fluctuations occur with which machine.

For the measurement, we used power meters from mystrom. With the appropriate app, we arrived at the following values.

How should the power consumption table of espresso machines be read? The machine is heated for 25 minutes. Subsequently, according to the test instructions for temperature measurement (see below), the extraction of 5 double espressos at approximately 1-minute intervals is simulated. After completing this simulation, power consumption is recorded. Subsequently, 2 hours later, a double espresso is simulated (5 s flush / 30 seconds water extraction) and power consumption is recorded. After another 2 hours, a double espresso is similarly simulated and the machine is cleaned. For this, backflushing is performed 5 times for 4 seconds each. Then the machine is switched off and power consumption is recorded.

The Lelit Mara X is the only machine in the test with an ECO mode. More and more machines are being built with eco mode. The Lelit Mara X's eco mode kicks in after 30 minutes and stops active boiler heating. In everyday use, this is actually somewhat annoying if you just barely miss the 30-minute window. One reason why we can't imagine the Lelit Mara X as a training machine in our home barista courses.

Interestingly, despite multiple reheating cycles, the machine doesn't consume more power than other machines. The insulated boiler greatly helps prevent large temperature drops, so after two hours there's still plenty of temperature in the boiler. In fact, the machine was also usable again after just 5 minutes (normally it heats for 25 minutes). Over the course of the test, the Lelit Mara X's power efficiency improves.

Additionally, the Xenia Espresso and BZ10 perform well – both are machines without a classical Faema E61 brewing group with circulating thermosiphon principle. In both machines, the brewing head is electrically heated. From an energy standpoint, this principle shows its potential. The Xenia Espresso also demonstrates that an appropriate brewing head by no means harms temperature constancy. Machines with large boilers and those without insulation perform particularly poorly.

Milk foam and steaming ability and cappuccino power

Dual-boiler espresso machines are characterized compared to single boilers by the fact that espresso can be extracted and milk steamed in parallel. How quickly the milk gets hot, how much force each machine brings to the 0.6 liter pitcher when steaming, and how steaming feels overall, we compared.

Michel Aeschbacher inserted the espresso and started extraction. After 10 seconds of running time, he briefly released condensation from the steam wand. After about 17 seconds, we started steaming.

In the direct comparison of the machines, we also gathered new insights for ourselves. The displayed boiler pressure is not a 1:1 indicator of force on the steam wand. Some machines, despite showing +1 bar, felt rather powerless when steaming, while other espresso machines delivered decent pressure with 0.8 bar.

Regardless of pressure, some machines heated the milk faster than others. In general, this allows for longer steaming before the milk gets too hot. This allows the stretching and rolling phase to be extended, which tends to lead – especially for latte art beginners – to an advantage: more time. Ideal performance is: powerful pressure with simultaneous slow heating.

Steaming ability in direct comparison

The Rocket Appartamento steams with a lot of power. It makes steaming fun, easily brings swirl into the whole pitcher, and yet doesn't heat the milk too quickly. Great for beginners and pros.

The Lelit Mara X has less force than the Appartamento. The built-up pressure is absolutely suitable for steaming. At the same time, the milk heats relatively slowly. Pretty good for beginners.

With the ACM Homey, the steam wand really delivers power. It steams and heats quickly. Requires some practice.

The Bezzera BZ10 also has plenty of power and easily gets the milk spinning, even if the perfect spot in the pitcher isn't found. Very suitable for steaming for ambitious beginners and pros.

The Elba 1 from 969.coffee also delivers solid performance. Michel's statement: «It might heat up a bit faster and simultaneously has less pressure. But that's more of a felt statement.» Overall good and we have nothing to complain about.

The Bezzera Magica also delivers good performance. Plenty of power and a nice rolling phase are guaranteed. Heats up quite quickly.

Simultaneous milk steaming during extraction isn't quite easy with the Xenia.

We studied the Xenia Espresso the most in terms of milk foam. It already had difficulties during our first test enabling simultaneous brewing and steaming. The Xenia has two modes: the classical espresso mode, which delivers very consistent temperature and correspondingly good espressos, and a reheating mode. If you press the start button during extraction to the right, the espresso mode runs. With a button press to the left, the Xenia reheats during espresso extraction and stabilizes the boiler pressure.

In espresso mode, the boiler pressure dropped below 0.5 bar. Difficult to nearly impossible to steam milk this way. The milk can't get properly moving, so many large bubbles remain on the milk.

In reheating mode, the pressure is more stable and no longer drops below 0.5 bar. It's then easier to steam. Compared to the other tested machines, steaming performance is still at the lower end of the table. However, the manufacturer is constantly working on workarounds and is very close to the user community. If milk steaming is more important than espresso performance, you can improve settings with a firmware switch. However, it seems more sensible to us to wait longer after espresso extraction, allowing the boiler pressure to stabilize. Milk foam performance improves significantly this way, though not perfectly.

The Profitec Pro 500 has markedly less power than the other Faema E61 brewing groups. Michel compares the steaming behavior to the Xenia button combination left (reheating mode). Interesting for us: the displayed boiler pressure stays high. In the pitcher, we feel little of it.

Michel has steaming fun with the Quick Mill Rubino. Nice rolling phase, good circulation. You can make good milk foam this way.

At the top of the flag flies the Rocket Mozzafiato Cronometro R. Steaming is powerful but also heats quickly. Definitely interesting for ambitious users.

The ECM Manufacture Mechaninka V Slim delivers solid steaming performance. "Not much and not little", Michel sums up the steaming.

The Quick Mil Andreja Premium PID lines up at the table end with Xenia and Profitec Pro. The pressure is insufficient to get the milk into complete rotation. Since we're already at the upper limit with brewing temperature, we can't increase boiler pressure further.

How is milk steamed?

In the first phase of steaming, we bring temperature and volume into the milk. Air is incorporated and bubbles form. This part of steaming is called the stretching phase.

In the second and subsequent rolling phase, the formed bubbles are broken down and the milk foam becomes creamy-silky and glossy. This consistency is very suitable for pouring latte art onto a cappuccino.

Temperature constancy during extraction and between extractions

To brew very good espresso, temperature constancy during the brewing phase is essential. In an article and video, Phillipp Schallberger and Michel Aeschbacher worked this out. In their comparison test, they recommend an average brewing temperature of 93 degrees. At temperatures of 88 degrees, the tasted coffees were unpleasantly sour, harsh, and had an astringent aftertaste. Channeling also occurred more frequently. At temperatures of 96 degrees, bitterness was overwhelming and the acidity was no longer balanced. Texture decreased, even though the concentration of dissolved coffee particles (TDS, strength) increased.

As part of our test series, we investigated two things.

1. Constancy during extraction. We noted how much the temperature deviated during an extraction from the 1st to the last second. As a standard extraction, we examined the second extraction of five extractions.
2. Family, shared apartment, and catering suitability. Anyone wanting only one espresso is less dependent on the third and fourth espresso still being at target temperature. But if several espressos are pulled back-to-back in a larger household on a typical morning, temperature constancy across multiple extractions matters. It's also important to give users confidence. If temperature is constantly fluctuating, it creates uncertainty when brewing.

How consistent does temperature remain over 25 seconds?

To measure constancy along brewing time, we compared temperature at three temperature points and considered the difference at 5 seconds, after 13 seconds, and after 22 seconds.

In the first few seconds, coffee grounds are saturated and the actual brewing temperature at the sensor must first be reached.

Overall, it can be stated that almost all machines deliver surprisingly good temperature constancy during the brewing time. Noteworthy are the Rocket Appartamento with a fluctuation of only 0.17 degrees between second 5 and 22. The Bezzera Magica fits in with a difference of -0.18 degrees. Furthermore, the Xenia (switch right), the Rocket Mozzafiato, the Elba 1, the Quick Mill Rubino, and also the ACM Homey deliver good results with less than 0.5 degree fluctuations during extraction. This is sensational and far better than we expected months ago.

The Quick Mill Andreja (0.53), the ECM Manufacture Mechanika V Slim (0.87), and the Lelit Mara X (0.89) also deliver good results. The Bezzera BZ10 comes to 1.02 and the Profitec Pro 500 to -1.44 – all perfectly acceptable. With the Profitec Pro 500, it should be noted that this drop occurs at the very end of extraction, where not much significant is being extracted from the coffee grounds anyway. It's possible that with some coffees, this temperature drop at the end could even have positive effects.

Important notes: for the measurement, we used the second espresso as the basis. We recommend using the first extraction to heat through the portafilter and to flush the shower to remove any residual cleaning powder.

Constancy across 5 extractions

"Who needs 5 extractions anyway", some of you may rightfully say. That's 10 espressos after all. Yes, but…

Do you even know what temperature you're at when it's constantly going up and down?! The Rocket Appartamento is a good example. The second extraction was nearly perfect in terms of constancy and temperature. While the first extraction had an average temperature of 93.98 degrees, extraction 5 was only at an average of 90.32 degrees. The Rocket performed in the mid-field of dual-boilers. Clearly a machine for two to three extractions and one that needs to be known and understood.

In comparison, the Xenia when activating extraction to the right resembles a straight line that increases by just 0.88 degrees over 5 extractions.

Even more consistently, the Rocket Mozzafiato delivers with a temperature loss of 0.47 degrees. However, we have another clear criticism point with the Rocket Mozzafiato. At highest boiler temperature, namely 124 degrees on the PID display, the machine only delivered 90.48 degrees in the 1st extraction. That's definitely too cold. Since no thermostat – but a PID controller with sensor – is installed, we couldn't raise the temperature ourselves either, which harmed the espresso quality. Lots of acidity – not delicious!

In terms of constancy across multiple extractions, these three machines are in a class of their own. With just over two degrees fluctuation, the BZ10, the Bezzera Magica -2.12, and the ECM Mechanika V Slim follow with -2.21 degrees.

The ACM Homey (3.28), the Andreja (-2.33), the Appartamento (-3.65) play mid-field. The Lelit Mara X performs worst with both switch positions (steam and brew mode).

The Profitec Pro 500, Quick Mill Rubino, and Elba 1 also score poorly.

The Lelit Mara X's performance is particularly problematic, especially since it shows such good performance in so many other categories. It's worth getting to know this machine, and the other machines that lose temperature, really well to get the most out of them.

Anyone buying one of the consistent machines like the Xenia, the Mozzafiato, or also Bezzera Magica knows what they have and can find the right temperature with less effort.

Heat-up time of the espresso machine

The heat-up time of the espresso machine sometimes determines the duration of your waking or sleeping state in the morning. In that sense, it's important! Bad news: if you wait for the first shot next to the espresso machine, you shouldn't buy a dual-boiler. Unfortunately, we have no good news for you. No machine is significantly faster hot than the magical 25-minute threshold. Sorry!

The Xenia Espresso is closest to acceptable brewing temperature after 18 minutes. However, we also measure only 88 degrees temperature, which isn't really delicious. If you're serious about the first espresso, wait your 25 minutes. Our Xenia model has a heating element built into the brewing group. There's also the option to install a second element and then the whole thing should go faster.

If we can test this at some point, we'll add it here.

Otherwise, our conclusion on heat-up time is: wait 25 minutes, use a timer, or buy a single boiler. With dual-boilers, it takes time for the boiler and brewing group to really reach temperature. If that stresses you, then that's not the right machine for relaxing.
