The QJA Espresso Machine takes the increasingly popular compact-home-espresso formula and adds one feature that immediately changes the way it feels to use: a touchscreen. Behind that modern interface is a conventional ground-coffee setup with a portafilter, single- and double-cup filter baskets, a steam wand, a removable 57.5-ounce water tank, a cup-warming surface, stainless-steel styling, and a pump rated at a maximum of 20 bar.

That combination places the QJA EM625 espresso machine in an interesting part of the market. It is much more hands-on than a capsule machine because grind size, coffee dose, distribution, tamping, and milk technique still matter. At the same time, it is less intimidating than the knobs, gauges, and exposed controls associated with traditional prosumer machines. The LED touch interface gives the front of the machine a cleaner, more approachable character, while the portafilter and steam wand keep the actual coffee-making process recognizable.

The 20-bar number deserves some perspective from the beginning. It is the maximum pump-pressure specification, not an instruction that espresso should be extracted through the coffee puck at 20 bar from beginning to end. Good espresso depends on the complete hydraulic system, basket resistance, grind, dose, flow, temperature, and coffee freshness. A larger pump number by itself does not make a better shot.

What makes this QJA more interesting in daily use is everything surrounding that pump: approximately 1.7 liters of removable water capacity, a narrow 5.3-inch body, 1400W heating/steam system, 51 mm brewing hardware, separate single- and double-cup baskets, touchscreen control, manual milk frothing, and enough flexibility to move from straight espresso to cappuccino, latte, Americano-style drinks, and iced recipes without changing machines.

This review focuses on those practical ownership details rather than dramatic claims about “café-quality” coffee. The important questions are how easy the QJA is to dial in, what the narrow body means on a real countertop, how the 57.5-ounce tank changes refill frequency, how useful the touchscreen remains after the novelty wears off, whether the steam system fits a beginner, what cleaning actually involves, and who should choose this machine instead of a more basic compact espresso maker or a faster premium alternative.

COMPACT TOUCHSCREEN ESPRESSO
QJA EM625 20 Bar Espresso Machine

The User: This QJA Fits Best

The strongest match is someone who wants to move beyond capsules without immediately buying a large enthusiast espresso setup. QJA still makes you handle real ground coffee, which means there is enough technique to learn something meaningful about espresso. You choose the coffee, adjust the grinder, fill the filter basket, distribute and tamp the grounds, lock in the portafilter, brew, and then steam milk manually when the drink requires it.

That hands-on routine separates it sharply from fully automatic machines. A bean-to-cup machine hides the grinder, dosing, and puck inside the chassis. QJA leaves those variables in your hands but simplifies machine operation through the touch interface.

Small kitchens are another obvious fit. Width is approximately 5.3 inches, which is unusually narrow for a machine with a portafilter and full-size removable tank. The design therefore works well in apartments, small kitchens, office coffee corners, and counters already shared with a grinder, kettle, toaster, or other appliances.

Milk-drink beginners are also likely to appreciate it. A proper steam wand involves more technique than an automatic frother, but learning to control the pitcher is useful if cappuccino, latte, flat white, or cortado becomes part of the routine. Unlike a one-touch milk system, the wand lets the user decide how much milk to texture and how much air to introduce.

The weaker match is an advanced espresso hobbyist expecting commercial-group temperature stability, pressure profiling, an industry-standard 58 mm ecosystem, dual boilers, or extensive internal adjustment. QJA is a compact consumer espresso machine rather than a miniature commercial platform.

QJA EM625 Pros and Cons

  • ✅ Large 57.5 oz removable water tank
  • ✅ 20-bar maximum pump rating
  • ✅ 1400W heating and steam system
  • ✅ LED touchscreen interface
  • ✅ 51 mm single- and double-cup filters

  • ❌ Manual milk steaming has a learning curve
  • ❌ 20-bar pump rating can be misunderstood as extraction pressure
  • ❌ 51 mm accessory ecosystem is smaller than 58 mm commercial-style platforms
  • ❌ Not a dual-boiler machine
  • ❌ Touch controls do not eliminate puck-preparation variables
  • ❌ Compact body gives less working space around the group and wand
  • ❌ Advanced temperature and pressure profiling are not the focus

Why the 5.3-Inch Width Matters More Than the 20-Bar Label

A pump-pressure number appears on almost every affordable espresso machine, which makes 15 bar versus 20 bar look like the obvious comparison. In real ownership, countertop dimensions may matter more.

The current QJA configuration is only about 5.3 inches wide while still carrying a 57.5-ounce removable tank. That width is important because espresso requires more than the machine itself. A grinder has to sit somewhere. You need room for a tamper, dosing tools, a cup, perhaps a milk pitcher, and enough elbow room to lock the portafilter into the group.

A wide espresso machine can force the grinder onto a different counter. A narrow one lets both pieces occupy the same coffee station. That improves the workflow every day, not just while comparing specification sheets.

The QJA is deeper than its face suggests, so measuring the entire counter remains important. The current B0F1LJWX5K configuration is approximately 11.4 inches deep and around 11.4 inches high. There also needs to be space behind or above the machine to remove and refill the water tank comfortably.

Understanding the 20-Bar Pump Correctly

QJA Espresso Machine Review

The QJA uses a pump rated to a maximum of 20 bar. That figure indicates available pump capability; it does not mean properly brewed espresso should be forced through the coffee bed at 20 bar for the entire shot.

Once water meets resistance from the basket and coffee puck, the hydraulic system behaves differently from an unrestricted pressure test. Grind size, coffee dose, tamp, basket design, and flow all affect resistance. That is why changing the grinder can dramatically alter extraction even though the pump itself has not changed.

If espresso gushes through the basket in a few seconds, “20 bar” cannot rescue a grind that is far too coarse. If water barely passes through, extra pump capacity does not make an excessively fine or overdosed puck correct.

I would therefore treat the pressure specification as confirmation that the machine uses a pump-driven espresso architecture, then spend far more time thinking about grinder quality, dose, coffee freshness, distribution, and beverage ratio.

The Grinder Matters More Than Many Beginners Expect

QJA accepts ground coffee rather than whole beans, so the grinder becomes the other half of the espresso system. A machine cannot make the grind finer after coffee enters the basket. It can only push water through what you prepared.

Espresso needs much finer control than drip coffee. One grinder step can sometimes move a shot from fast and thin to slow and heavy. An ordinary blade grinder gives very little repeatability because it chops rather than controlling particle spacing. A burr grinder designed to reach the espresso range is substantially more useful.

Freshness matters as well. Fresh beans are not magic, but coffee gradually loses volatile aroma after roasting and loses it much faster after grinding. Grinding immediately before loading the basket keeps more of those aromatic compounds available during extraction.

For a beginner, the easiest approach is consistency. Keep the same basket, similar coffee dose, same tamping routine, and same target drink size while moving the grind in small steps. Once the flow looks reasonable and the coffee tastes balanced, save that grinder position as a reference for the bag.

The 51 mm Brewing System

The current configuration includes a 51 mm portafilter setup with separate one-cup and two-cup filters. This smaller diameter is common among compact home espresso machines.

Basket diameter changes puck geometry. The same mass of coffee in a narrower basket forms a deeper puck than it would in a wider 58 mm commercial-style basket. That does not automatically make extraction better or worse, but it changes accessory compatibility and the way the puck responds to grind and dose.

When purchasing a replacement tamper, dosing funnel, puck screen, distribution tool, or basket, compatibility matters. An accessory labeled simply “espresso size” is not enough; it needs to match the actual 51 mm system appropriately.

The single basket can be useful when a smaller coffee dose is genuinely wanted, but the double basket is often easier to dial in consistently because there is more coffee mass and a more forgiving puck shape. Beginners do not need to use the single basket simply because they want one drink.

The Touchscreen Simplifies Machine Control, Not Espresso Technique

QJA Espresso Machine Review

The LED touchscreen is visually the feature that separates the QJA from many inexpensive compact machines with physical rocker switches or mechanical buttons. It gives the front panel a clean appearance and makes the major operating functions easy to identify.

What the screen does not do is automate the variables in the portafilter. It cannot correct uneven distribution, remove clumps, compensate perfectly for stale beans, or know that today’s roast needs a slightly finer grind than yesterday’s.

That distinction is important because touchscreen espresso machines can look more automatic than they really are. QJA remains fundamentally a hands-on ground-coffee machine. The interface simplifies commands to the machine; the user remains responsible for preparing the coffee.

I actually see that as a positive for its intended audience. Beginners get a modern control surface without losing the opportunity to learn why espresso behaves differently when grind, dose, and preparation change.

Brewing Espresso: Start With the Recipe, Not the Pump

A useful espresso routine begins with a repeatable dose rather than trying to imitate an arbitrary 25-second shot time. Different coffees, baskets, grinders, and doses can produce excellent results at different flow rates.

For the first setup, choose the double basket, use freshly ground espresso coffee, distribute it as evenly as possible, tamp level, lock the portafilter into place, and brew into a cup that lets you see the flow. If you have a small scale, measuring the beverage yield makes troubleshooting much easier than judging volume by crema height.

If the espresso runs very quickly and tastes sharp or watery, grind finer before assuming the machine is weak. If almost nothing comes through and the pump sounds heavily loaded, grind coarser or reduce the dose rather than repeatedly forcing the same clogged puck.

Taste decides where to stop. A technically beautiful stream can still produce coffee you do not enjoy. Espresso is concentrated enough that small grind changes can alter acidity, sweetness, bitterness, and texture noticeably.

Single vs. Double Basket Workflow

The QJA includes separate one-cup and two-cup filters. That provides flexibility, but the double basket is the one I would use while learning the machine.

Single espresso baskets often have less forgiving geometry, so small errors in distribution can have a larger effect on water flow. The double basket provides a more substantial puck and usually gives a beginner more room to learn how grind and dose interact.

A “double” also does not require drinking the coffee as one straight shot. It can become the espresso base for a cappuccino, latte, Americano-style drink, mocha, iced latte, or affogato.

Once the double basket is predictable, experimenting with the single basket becomes much easier because you already know the grinder range and general behavior of the machine.

The 57.5 Oz Water Tank Is a Real Daily Advantage

QJA Espresso Machine Review

A 57.5-ounce reservoir—roughly 1.7 liters—is generous for a machine this narrow. Espresso itself consumes little water, but owners often underestimate how much water disappears through flushing, warming cups, cleaning the group, and purging the steam system.

A small tank can make a compact espresso machine feel more tedious than its dimensions suggest because every few drinks begin with another trip to the sink. QJA avoids much of that friction.

The reservoir is removable, so refilling does not require accurately pouring a heavy jug behind the machine. Removing the tank also makes it easier to inspect for mineral film and wash periodically.

The tradeoff is rear clearance. Large removable tanks need somewhere to go when lifted from the machine, so cabinets directly above a very shallow counter may affect access even though the machine itself is compact.

Steam Wand: The Most Skill-Dependent Part of the QJA

QJA Espresso Machine Review

The steam wand is where this machine stops feeling like a touchscreen appliance and starts feeling like a traditional espresso setup. Milk texture depends on pitcher position, steam depth, amount of air introduced, starting milk temperature, pitcher size, and when steaming stops.

For a latte, the goal is not a mountain of dry foam. You want the milk and small bubbles integrated into a glossy texture that pours rather than falling into the cup in separate layers.

Start with cold milk in a suitable metal pitcher. Purge any condensation from the wand first. Position the tip near the surface during the early stage to introduce a controlled amount of air, then place it slightly deeper and create circulation so larger bubbles break down while the milk heats.

Cappuccino can tolerate more aeration. A flat-white-style drink needs less. Oat, soy, and other plant-based milks can work, but formulations designed for steaming tend to behave more predictably than very thin versions with little protein or stabilizing structure.

The essential maintenance step happens immediately afterward: wipe the wand while the milk film is still fresh and purge steam briefly so residue does not dry inside or around the tip.

Espresso to Steam: Understanding the Single-System Rhythm

A compact machine in this class should not be expected to behave like a dual-boiler espresso machine that can brew and steam independently at the same time.

Espresso extraction and milk steaming require different temperature conditions. Steam needs substantially more heat than brewing water, so compact systems move between modes rather than maintaining two independent boilers.

For one latte, this is not a major inconvenience. Brew the espresso, switch to steam, texture the milk, wipe and purge the wand, then serve. The workflow only becomes more noticeable when making several milk drinks back to back.

If entertaining six cappuccino drinkers every weekend is the normal use case, a more powerful machine with faster transitions or independent brew/steam systems deserves consideration. QJA is more naturally a one- or two-drink-at-a-time machine.

QJA EM625: The Ownership Equation

The machine saves width and modernizes the interface without removing the core craft of ground-coffee espresso. Its biggest strengths are a large reservoir, narrow footprint, manual steam control, and straightforward access to real portafilter brewing.

Daily Strength

The 57.5 oz tank reduces refills, while the touchscreen keeps machine operation approachable for a first espresso setup.

Daily Limitation

A good grinder, careful puck preparation, steam-wand cleaning, and some technique are still required. Touch controls cannot automate those fundamentals.

My Bottom Line

Choose it when you want a narrow entry-level espresso station with hands-on milk control and a modern interface—not when you want fully automatic coffee.

A Practical Morning Workflow

A smooth routine begins with the grinder rather than the touchscreen. Turn the machine on, check the tank, and allow the brewing system and portafilter to warm while the coffee is ground.

Dose into the preferred filter basket, distribute the coffee evenly, tamp level, clear stray grounds from the basket rim, and lock the portafilter into the group. Position the cup, select the brew function, and watch the first part of the extraction closely enough to catch an obviously incorrect grind.

For a straight espresso, cleanup can begin almost immediately after brewing. For a latte or cappuccino, switch to steam, purge the wand, texture the milk, then wipe and purge the wand again before the residue dries.

After serving, remove the puck, rinse the basket, flush a little water through the group as appropriate, wipe coffee from the shower area, and empty the drip tray when required.

Once this becomes routine, the manual preparation is not particularly slow. The largest time variable is usually the grinder and milk technique rather than pressing buttons on the machine.

Cup Warmer: Useful, but Give It Time

The top warming area is useful because espresso volume is small and loses heat quickly when poured into a cold cup. Warm ceramic preserves serving temperature more effectively than extracting into a mug that has been sitting in a cool cabinet.

Passive cup-warming surfaces generally need time before they become noticeably warm. If the machine has only just been switched on, rinsing the cup with hot water is faster.

The warming surface also makes a convenient temporary place for the cups used most frequently, provided the top of the machine remains unobstructed enough for normal ventilation and tank access.

Cleaning: What I Would Do Daily

The old idea that espresso-machine maintenance is similar to cleaning a basic drip brewer understates what is happening around a portafilter and steam wand. The routine is still manageable, but different components need different treatment.

After each espresso session, knock out the used coffee, rinse the filter basket and portafilter, wipe loose grounds from the group area, and rinse the drip tray when coffee has collected inside it.

After every milk drink, wipe the steam wand immediately and purge it. Dried milk is much more difficult to remove and can obstruct the steam outlet.

Do not assume a portafilter, filter basket, or other brewing component is dishwasher-safe unless the instructions for your exact accessory specifically permit it. Dishwasher detergent and heat can damage finishes, handles, seals, or aluminum components on some espresso equipment.

The removable water tank should be rinsed periodically and allowed to dry when the machine will sit unused. Fresh water is better for coffee than repeatedly topping up old water indefinitely.

Do Not Blind-Backflush an Entry-Level Machine Without Confirmation

One of the most important corrections to the older care routine is the recommendation to insert a blind filter and backflush automatically every couple of weeks.

Backflushing is appropriate only for machines whose group design and valves are specifically designed to support it. Forcing a blind basket against a machine that does not route pressure correctly can stress components rather than clean them.

Use the cleaning procedure intended for the exact QJA model. Clean the removable brewing parts manually, flush the group normally where appropriate, keep the steam wand clear, and use the machine’s supported cleaning functions rather than importing maintenance routines from commercial-style machines.

The same principle applies to chemical cleaners. More aggressive cleaning is not automatically better maintenance.

Descaling and Water Quality

Scale forms when minerals in water remain behind as the heating system repeatedly raises water temperature. Hard-water households accumulate those deposits faster.

Filtered drinking water can reduce scale and improve cup flavor when the local supply tastes strongly chlorinated or mineral-heavy. However, completely demineralized water is not automatically ideal for espresso because mineral composition also affects extraction.

Use a descaling product and procedure suitable for the machine rather than improvising a highly concentrated household acid solution. The correct interval depends on water hardness and how frequently the machine is used.

A large reservoir can tempt the owner to keep adding new water over old. I prefer emptying and refreshing it periodically so the tank itself stays cleaner and the coffee begins with fresh-tasting water.

What Becomes Noticeable After the Newness Fades

The touchscreen is likely to receive the most attention on day one. Several months later, I suspect the 57.5-ounce tank and narrow width would matter more.

A control panel is used for seconds at a time. Counter space is occupied all day. The reservoir determines how often the machine interrupts the routine. Those unglamorous design choices influence ownership constantly.

The steam wand also changes character over time. At first it creates a learning curve. After the milk technique becomes familiar, manual control becomes an advantage because you can deliberately produce different textures instead of accepting one automatic foam style.

The grinder may become the first limitation instead of the machine. A beginner often focuses on the espresso maker because it is visually dominant, but increasingly precise shots make grinder inconsistency easier to notice. Upgrading the grinder later can improve the QJA experience without replacing the QJA itself.

The 51 mm system is another long-term consideration. Basic replacement accessories are widely available, but someone eventually building a collection around commercial-style 58 mm baskets, tampers, distribution tools, and portafilters would be investing in a different ecosystem.

QJA EM625: Extended-Use Assessment

The long-term ownership questions are less about the 20-bar label and more about grinder quality, steam technique, 51 mm accessory compatibility, cleaning habits, and how much value the narrow body and large reservoir add to your kitchen.

Technical Specifications & Daily Features

The current QJA EM625 configuration uses a 20-bar maximum-pressure pump, 1400W system, LED touchscreen, removable 57.5 oz / approximately 1.7 L water tank, manual steam wand, cup-warming surface, ground-coffee input, 51 mm portafilter system, and separate one-cup and two-cup filters. The body is approximately 5.3 inches wide and about 11.4 inches high, making it particularly attractive for a narrow countertop coffee station.

Pros & Cons After 30 Days of Use

The strengths most likely to remain meaningful are the slim width, unusually generous reservoir, easy-to-read touchscreen, conventional ground-coffee flexibility, manual milk control, and ability to change grinders later without replacing the machine. The recurring compromises are the need to dial in espresso manually, clean the steam wand immediately after milk use, work within the 51 mm accessory system, and switch between brewing and steaming rather than relying on simultaneous dual-boiler operation.

My Final Verdict

The QJA makes sense as a compact first portafilter machine for someone who wants to learn real espresso preparation without giving up a modern interface. Its 20-bar pump rating is much less important than its large tank, narrow chassis, usable steam wand, and compatibility with normal ground coffee. Buyers wanting automated bean-to-cup drinks should look elsewhere; buyers who want hands-on espresso in a small footprint have a much stronger reason to consider it.

What I Like Most About the QJA

The best feature is the balance between width and water capacity. Compact espresso machines often achieve small dimensions partly by fitting a correspondingly tiny reservoir. QJA manages to stay narrow without turning refilling into a constant part of the routine.

I also like that the machine uses ordinary ground coffee. That keeps bean choice open rather than locking the owner into a capsule catalog. Espresso becomes more demanding, but it also becomes much more flexible.

The touchscreen is sensible because it modernizes the user experience without trying to automate away the portafilter. It is convenience layered onto manual coffee preparation rather than pretending to be a bean-to-cup machine.

Finally, the steam wand gives the machine room to grow with the owner. Milk texture that seems difficult during the first week can become one of the most satisfying parts of the routine once technique improves.

What I Would Improve

The first improvement would be clearer feedback about brewing conditions. A real-time pressure gauge or more explicit extraction information could help beginners connect grind changes with what happens inside the puck.

I would also like an even more clearly documented set of programmable parameters on the touchscreen. Modern controls are most useful when they expose repeatable adjustments rather than simply replacing physical buttons.

A stainless tamper sized precisely for the basket would improve the out-of-box experience. Scoop-and-tamper combination tools are convenient starter accessories, but a solid standalone tamper gives better control over level pressure.

Finally, faster recovery between espresso and milk steaming would benefit households making several lattes in a row. That is one of the areas where more expensive thermal systems earn their price.

QJA vs. Breville Bambino

The Breville Bambino takes a more performance-focused approach to compact espresso. It uses Breville’s ThermoJet heating system, a larger 54 mm portafilter platform, and is designed around an extremely fast start-up.

QJA counters with a touchscreen interface and a substantially larger stated water tank while still maintaining a narrow body. The QJA therefore has a strong convenience argument for someone who dislikes frequent refilling and prefers digital controls.

The Bambino has a larger established accessory and support ecosystem and places more emphasis on the thermal and extraction architecture. QJA is appealing when budget, interface, tank capacity, and compactness carry greater weight.

Both still need a grinder and good puck preparation. Neither machine eliminates the need to learn espresso simply because one heats faster or the other has a touchscreen.

QJA vs. CASABREWS CM5418

The CASABREWS CM5418 is one of the closer conceptual alternatives. It also uses a 20-bar pump, compact body, 51 mm portafilter system, single- and double-cup brewing, removable tank, and manual steam wand.

The current CM5418 emphasizes physical button control, a pressure gauge, a 34-ounce reservoir, low-pressure pre-infusion, and adjustable shot volume. QJA emphasizes its LED touchscreen and much larger 57.5-ounce reservoir.

That creates a useful distinction. The CASABREWS gauge gives visual extraction feedback. QJA gives more water capacity and a digital front interface.

For a beginner who wants to watch pressure behavior while learning, the gauge can be helpful. For someone who prioritizes a large tank and touchscreen controls in a narrow package, the QJA formula may feel more natural.

Who Should Buy the QJA EM625?

  • First-time portafilter users who want a modern interface without moving to capsules.
  • Apartment dwellers who need a machine around 5.3 inches wide.
  • Latte and cappuccino drinkers willing to learn manual milk steaming.
  • Ground-coffee enthusiasts who want freedom to change beans rather than buy proprietary capsules.
  • Users tired of small water tanks who appreciate the approximately 57.5-ounce reservoir.
  • Touchscreen fans who prefer a clean digital front panel over rows of mechanical switches.

Who Should Skip It?

A bean-to-cup machine is more appropriate if grinding, dosing, tamping, and milk technique sound like chores rather than part of the experience. A larger prosumer machine makes more sense if 58 mm accessories, advanced temperature control, simultaneous brewing and steaming, or extensive pressure management are priorities. A capsule machine is simpler when speed and cleanup matter more than fresh-bean flexibility.

How to Get Better Espresso From the QJA

Use an espresso-capable burr grinder. This is the most important companion equipment. Consistent fine adjustment makes dialing in dramatically easier.

Warm the portafilter and cup. Small espresso volumes lose heat quickly. Give the brewing hardware a little thermal preparation rather than focusing only on machine start-up time.

Keep puck preparation level. Uneven distribution encourages water to find easier paths through the coffee, producing uneven extraction.

Change one variable at a time. If a shot tastes wrong, do not simultaneously change grind, dose, yield, coffee, and tamp. Small controlled adjustments teach you much more.

Use fresh, appropriate water. Espresso is mostly water, and excessive hardness also accelerates scale inside the machine.

Purge and wipe the steam wand immediately. This single habit prevents many of the frustrating milk-system problems beginners experience.

Do not chase crema. Crema color and thickness can be influenced by roast level, bean age, Robusta content, basket behavior, and pressure. Taste the espresso instead of judging quality from the foam layer alone.

Final Verdict

The QJA EM625 is more interesting as a compact espresso system than as a “20-bar machine.” Pump ratings are easy to market. A 5.3-inch width, 57.5-ounce removable tank, 51 mm ground-coffee brewing system, manual steam wand, and clear touchscreen affect ownership much more directly.

Its narrow body is particularly well judged because espresso requires a grinder beside the machine. Saving width on the brewer creates room for the equipment that actually determines grind quality. The large reservoir then offsets one of the usual frustrations of compact machines by reducing refill frequency.

The touchscreen makes machine operation approachable, but it does not turn espresso into a push-button process. Grinder choice, coffee freshness, basket dose, distribution, tamping, beverage yield, and milk technique still matter. That is exactly why the QJA can be a useful first step into hands-on espresso rather than merely another automated appliance.

I would choose it for a beginner who genuinely wants to learn espresso and milk texturing but has limited counter space and appreciates digital controls. It also makes sense for an apartment, office, or small household where one or two drinks at a time are normal.

I would skip it if the goal is automatic bean-to-cup coffee, simultaneous high-volume brewing and steaming, a 58 mm prosumer ecosystem, or extensive temperature and pressure profiling. Those requirements belong to different machine categories.

For the intended user, the ownership equation is convincing: a real portafilter, actual steam wand, large tank, compact body, and modern controls without the footprint or complexity of a much larger espresso station.

Frequently Asked Questions

Is the QJA EM625 a 20-bar espresso machine?

Yes. The current EM625 configuration uses a pump rated at a maximum of 20 bar. That specification describes pump capability rather than indicating that espresso should continuously extract through the coffee puck at 20 bar.

What size portafilter does the QJA use?

The current configuration uses 51 mm brewing hardware and includes separate one-cup and two-cup filters.

How large is the QJA water tank?

The removable reservoir holds approximately 57.5 ounces, or about 1.7 liters. That is generous relative to the machine’s narrow body.

Does it have a touchscreen?

Yes. The EM625 uses an LED touch interface rather than relying solely on conventional front-mounted switches.

Does the QJA grind coffee beans?

No built-in grinder is part of this configuration. It uses ground coffee, so an espresso-capable burr grinder is one of the most useful companion purchases if you want to brew from whole beans.

Can I use pre-ground espresso coffee?

Yes. Ground coffee is the normal input. Espresso-specific pre-ground coffee can be convenient, although a capable grinder gives much more control over flow and extraction.

Does it make single and double espresso?

The machine includes one-cup and two-cup filters, allowing smaller and larger coffee doses.

Does the QJA froth milk?

Yes. It includes a manual steam wand for texturing milk for drinks such as latte and cappuccino.

Can it make latte art?

Latte art depends primarily on producing glossy microfoam and learning pouring technique. The steam wand gives you manual control, but consistent latte-art milk takes practice.

Can I steam oat milk?

Yes. Plant-based milks can be steamed, although formulations marketed for barista use generally texture more predictably than very thin versions.

How wide is the QJA espresso machine?

The current configuration is approximately 5.3 inches wide, making it particularly useful on counters where the machine must share space with a grinder.

Does it include a cup warmer?

Yes. A cup-warming surface is included on the machine. For very fast starts, rinsing a cold cup with hot water can warm it more quickly.

Should I backflush the QJA with a blind basket?

Do not blind-backflush any espresso machine unless the procedure is specifically supported for that exact model and group design. Follow the QJA cleaning procedure rather than assuming commercial-machine maintenance routines apply.

How often should I descale it?

The correct interval depends on water hardness and usage. Hard water requires more frequent mineral maintenance. Appropriate filtered water can reduce scale accumulation.

Is the QJA good for beginners?

It can be a good beginner machine because the touchscreen makes machine operation straightforward while the portafilter and steam wand still teach the core skills of espresso preparation and milk texturing.

Is it better than a capsule machine?

It offers much more coffee choice and control because you can use ordinary ground coffee, but it also requires a grinder or suitable pre-ground coffee, puck preparation, and more cleaning. A capsule machine remains easier when convenience is the dominant priority.

Who should skip the QJA?

Skip it if you want fully automatic bean-to-cup drinks, require commercial-style 58 mm hardware, need simultaneous high-volume steaming and brewing, or have no interest in learning how grind size and puck preparation affect espresso.

Hello, I'm The Author and Editor of the Blog One Hundred Coffee. With hands-on experience of decades in the world of coffee—behind the espresso machine, honing latte art, training baristas, and managing coffee shops—I've done it all. My own experience started as a barista, where I came to love the daily grind (pun intended) of the coffee art. Over the years, I've also become a trainer, mentor, and even shop manager, surrounded by passionate people who live and breathe coffee. This blog exists so I can share all the things I've learned over those decades in the trenches—lessons, errors, tips, anecdotes, and the sort of insight you can only accumulate by being elbow-deep in espresso grounds. I write each piece myself, with the aim of demystifying specialty coffee for all—for the seasoned baristas who've seen it all, but also for the interested newcomers who are still discovering the magic of the coffee world. Whether I'm reviewing equipment, investigating coffee origins, or dishing out advice from behind the counter, I aim to share a no-fluff, real-world perspective grounded in real experience. At One Hundred Coffee, the love of the craft, the people, and the culture of coffee are celebrated. Thanks for dropping by and for sharing a cup with me.
