Jura ENA 4 review: a small, quiet black coffee machine with big espresso manners

Jura ENA 4 at a glance

First impressions of the Jura ENA 4

Most bean-to-cup machines take over a corner of the counter.

The Jura ENA 4 barely takes up a corner of a corner.

It's about 27 centimeters wide and 32 centimeters tall, with a tall, clear water cylinder on the side that looks almost like a carafe.

On my counter, it looked more like a design object than an appliance.

The second thing I noticed was the simplicity.

There's a small monochrome icon display, a handful of tactile buttons and a pair of coffee spouts.

No touchscreen, no milk pipe and no hot water outlet.

My first espresso was a pleasant surprise.

It came out sweet and balanced, under a dense, golden crema that stayed put.

For a machine this small, that's a real achievement.

The ENA 4 fits beside the sink with room to spare for mugs.

What the Jura ENA 4 actually is

The ENA 4 is a compact, fully automatic, bean-to-cup machine for espresso and black coffee.

It grinds, doses, compresses and brews the coffee, then drops the used puck into a bin inside the drip tray.

It's the successor to Jura's earlier entry machine, refined for better espresso in the same tiny footprint.

Inside is a thermoblock✕ThermoblockA compact heater that warms water as it flows through, instead of keeping a whole boiler hot. It heats up fast and uses less standby energy. that reaches brewing temperature within seconds of a cold start.

The pump is rated at 15 bar.

The brew unit✕Brew unitThe chamber inside an automatic machine that receives the ground coffee, presses it into a puck, pushes hot water through it and then ejects the used grounds. is smaller than on Jura's full-size machines, taking about 6 to 10 grams per cycle.

For stronger drinks, the ENA 4 simply runs two cycles.

Jura ENA 4 design and setup

The Jura ENA 4 measures 27.1 × 32.3 × 44.5 cm, or 10.7 × 12.7 × 17.5 inches.

It's low enough to sit under any standard wall cabinet with plenty of room to open the hopper lid.

It's still fairly deep, so check your counter.

The cylindrical water tank

The water tank is a tall, clear cylinder on the side.

It looks great and shows the water level at a glance.

At about 1.1 liters, though, it's small.

The bean hopper

The hopper on top holds about 125 grams of beans under an aroma-preserving lid.

That's roughly a week's worth for one espresso drinker, and a few days for two.

The small size does mean beans never sit long enough to go stale.

The drip tray

The drip tray is a multi-piece design with an internal flap that stops water sloshing when you pull it out.

The grounds bin sits inside it and holds about 10 pucks.

The machine counts brewing cycles to know when the bin is full, rather than using a float sensor.

That means you need to leave the tray out for a few seconds when you empty it, so the counter resets.

Our tip: Leave the drip tray out for at least five seconds when you empty it, so the grounds counter resets properly.

The clear water cylinder is the ENA 4's signature design touch.

Display and buttons

The ENA 4 uses a small monochrome icon display with tactile buttons.

There's a button for espresso, one for coffee, a strength button and a settings button.

It's about as simple as a bean-to-cup machine gets.

Anyone in the house can use it within a minute.

The settings menu covers the essentials: water hardness, filter activation and the auto switch-off timer.

Strength levels

The strength button changes how much coffee goes into each brew.

Our tip: Use the strong setting and a double press when you want a full-bodied espresso, because one small cycle tops out around 10 grams.

The grinder

The ENA 4 grinds with Jura's Professional Aroma Grinder and its conical burrs✕Conical burrsA cone-shaped cutting part that turns inside a ring. They grind evenly at fairly low speed, which keeps heat and noise down..

It's one of the quieter grinders I've used, with a low, soft hum rather than a sharp whine.

A dial adjusts the fineness.

As with every Jura grinder, only change it while the grinder is running, so beans don't jam between the burrs.

With medium-dark beans, I settled just finer than the middle.

Only use non-oily beans in the hopper, because oily beans can clog a small grinder quickly.

Our tip: After any grind change, wait two or three drinks before judging, because some old coffee is still in the chute.

Jura ENA 4 espresso performance

The espresso is the ENA 4's strongest point.

Each shot starts with pre-infusion✕Pre-infusionA short, gentle soak of the coffee before full pressure. It lets the puck swell evenly so water doesn't rush through weak spots., which soaks the compacted coffee evenly.

Then Jura's Pulse Extraction Process✕Pulse Extraction Process (P.E.P.)Jura's method of pushing hot water through the coffee in short, rapid bursts instead of one steady stream. It lengthens contact time for short drinks, giving a fuller flavor. pushes water through in short bursts.

That gives short drinks more contact time and more flavor without more water.

How it tasted

On the strong setting, the espresso had a dense, finely textured, golden crema✕CremaThe golden-brown foam on top of an espresso. It forms when pressure pushes gases and oils out of freshly ground coffee. that held for minutes.

The flavor was balanced, with well-developed sweetness and controlled acidity.

I didn't taste any harsh astringency or burnt bitterness.

There was very little sediment in the bottom of the cup.

The results stayed consistent when I switched between bean types, with just a strength change needed.

The double espresso

A double press makes the ENA 4 grind, brew, eject the puck, then grind and brew again into the same cup.

That gives a full-bodied double without overloading the small brew unit.

Bean by bean

Over the month, I ran four different coffees through the ENA 4.

A chocolatey medium-dark espresso blend was the easy favorite, with thick crema and a sweet, rounded finish.

A Brazilian medium roast tasted nutty and soft, with low acidity, and worked well as a long coffee.

An Ethiopian light roast was bright and floral, but it needed a finer grind and a double press to avoid tasting sharp.

A dark Italian-style blend gave the most crema, but its oily surface made me nervous about the small grinder, so I only used one bag.

The machine handled all four without fuss, and only the strength and grind needed changing between them.

Temperature in the cup

The thermoblock heats water quickly and holds it steady for short drinks.

The espresso tasted properly hot when I used a warm cup.

In a cold, thick ceramic cup, it cooled noticeably within a minute, which is common with small shots.

Consistency

What impressed me most was how repeatable the ENA 4 was.

Once I'd found my settings, the tenth espresso of the week tasted like the first.

That's the real advantage of a bean-to-cup machine over a manual setup.

You don't need any skill on a sleepy morning, and the machine doesn't have bad days.

Long coffee

The coffee button makes a lungo-style long coffee.

The whole cup of water passes through the coffee, which gives a smooth, soft cup.

At small mug sizes, it was pleasant and balanced.

At large mug sizes, a single small dose stretched too far and tasted thin.

A double press fixed that, with two cycles into one mug.

No hot water

There's no hot water spout, so you can't make a two-step americano or tea from the machine.

For an americano, I pulled a double espresso and topped it up from the kettle.

It tasted cleaner and brighter than a single long pour.

Our tip: For a big mug, make a double espresso and add kettle water instead of running one long coffee.

Pre-ground coffee and decaf

The pre-ground coffee✕Pre-ground bypassA separate chute that sends already-ground coffee straight to the brew unit, skipping the grinder. Handy for decaf without emptying the bean hopper. chute on top opens with a small lever.

Add one level scoop of espresso-fine coffee, close it and press your drink button.

The machine detects the manual dose, skips the grinder and brews as usual.

Use espresso-fine coffee, not coarse filter grind.

Coarse grounds let water rush through and taste weak, while very fine powder can block the flow.

Our tip: Buy decaf ground for espresso, not for filter coffee, so it brews properly through the chute.

What about milk drinks?

The Jura ENA 4 has no milk system.

That keeps it small, simple and easy to clean.

If you want an occasional cappuccino, pair it with a separate electric milk frother.

Pull a double espresso, froth the milk while it brews and pour it over.

If you'd use a frother every day, a machine with a built-in milk system will save you time.

Cleaning and maintaining the Jura ENA 4

With no milk system, daily care is quick.

The thermoblock rinses the brew channels when the machine warms up.

I emptied the grounds bin, rinsed and dried it, and cleared water from the tray channels.

Mild soap and warm water are fine, but avoid abrasive scrubbers.

The water tank

Rinse the cylindrical tank regularly to stop a film forming.

Filter changes

To change the filter, lift the tank from its side dock, open the holder and pull the old cartridge out.

Push a new one into the socket at the bottom, latch it, refill with cold water and put the tank back.

Then run the filter rinse from the settings menu to purge air.

Tablet cleaning

When prompted, drop a Jura cleaning tablet into the pre-ground chute, put a large container under the spouts and start the program.

The machine alternates hot water flushes with the cleaning solution.

The brew unit is fixed inside, so this program is how it gets cleaned.

Descaling✕DescalingRunning a mild acid solution through the machine to dissolve mineral scale left by hard water. Scale slows heating and can block pipes.

If you don't use a filter, or your water is very hard, the machine asks for descaling.

My estimate of hands-on daily cleaning time.

What daily use is really like

My mornings with the ENA 4 were quick and quiet.

Check the tank, put a warm cup under the spouts, choose a strength and press a button.

The thermoblock was ready within seconds of a cold start.

After a full power-down, it runs a short heat-and-rinse first.

The capacity trade-off

The small tank, hopper and grounds bin are the price of the small footprint.

For two espresso drinkers, I refilled the tank about once a day, topped up the hopper every few days and emptied the bin every three or four days.

For one person, it's barely noticeable.

For a family, it would get tiresome.

The ENA 4 also comes in white, which suits a bright kitchen.

The app

There's a port on the back for Jura's optional connectivity adapter.

With it, the J.O.E. app lets you adjust drink volume and strength, check maintenance and start a cleaning cycle from your phone.

It also shows lifetime drink counts and filter status.

It's nice to have, but the ENA 4's buttons are so simple that I rarely missed it.

Moving up from a capsule machine

Many people who look at the ENA 4 are coming from a capsule machine.

It's a natural step, because the footprint is similar and the operation is just as simple.

The difference is in the cup.

Capsule coffee is ground weeks or months before you drink it.

The ENA 4 grinds whole beans seconds before brewing, so the aromas haven't had time to fade.

In side-by-side tasting, the ENA 4's espresso had more sweetness, a thicker crema and a longer, cleaner finish.

What changes in your routine

With capsules, you drop in a pod and press a button.

With the ENA 4, you fill a hopper every few days and empty a grounds bin instead of a pod bin.

The daily effort is about the same.

You also choose your own beans, which opens up a whole world of roasters and flavors.

Cost per cup

Whole beans usually cost far less per cup than capsules.

Over a year of daily espresso, that difference adds up.

The ENA 4 costs more up front, so the savings take time to build.

Our tip: Start with a medium-dark espresso blend from a local roaster, because it shows off the jump from capsules most clearly.

The ENA 4 in a small office

I also spent a few days with the ENA 4 in a small home office shared by two people.

Its quiet grinder was a big plus, because calls and coffee could happen in the same room.

The simple buttons meant no one needed instructions.

The small containers were the limit again.

With two people drinking three or four coffees each, the tank needed refilling twice a day.

For an office of three or more, a machine with a larger tank and grounds bin would make more sense.

For a solo home office, the ENA 4 is close to perfect.

My four weeks with the ENA 4

Week one: settling in

The first few espressos were a little weak while the grinder settled.

By day three, I had a grind just finer than the middle and the strong setting for espresso.

Week two: the double-press habit

In week two, I started double-pressing almost everything.

Two small cycles into one cup gave more body than any single setting.

Week three: living with the small containers

Week three was when the small containers became part of my routine.

I refilled the tank each morning and emptied the grounds bin every few days.

It became automatic, but it's worth knowing before you buy.

Week four: maintenance

In week four, I changed the filter and ran a tablet cleaning cycle.

Both took a few minutes, and the espresso tasted fresh and clean afterward.

Beans and water

Use fresh, non-oily whole beans within a few weeks of the roast date.

Medium and medium-dark roasts worked best.

Oily beans are a particular risk in a small grinder.

Fill the tank with fresh, cold water.

Use the filter if your water is moderately hard or harder.

Common mistakes to avoid

The Jura ENA 4 is simple, but a few habits make a difference.

What I would change

A slightly bigger grounds bin and water tank would make a big difference.

A small hot water outlet would also make the ENA 4 far more versatile.

Is the Jura ENA 4 worth the money?

The ENA 4 is a premium compact machine.

Its value depends on your household and your kitchen.

For one or two black coffee drinkers with little space, it's one of the best small bean-to-cup machines I've used.

For a family, the constant refilling and emptying would wear thin.

Ask yourself three questions before you buy.

Do you drink fewer than four coffees a day at home? Is your counter space limited? And do you drink your coffee black?

If the answers are yes, the ENA 4 is easy to recommend.

If you answered no to the first question, look at a full-size machine with a bigger tank and grounds container.

If you answered no to the third, choose a model with a built-in milk system.

Check what's included where you buy, because filters, cleaning tablets and the app adapter vary between bundles.

The ENA 4's small display sits above a single pair of spouts.

How it compares with other espresso setups

The most useful comparison is with the types of machines you're likely choosing between.

The Jura ENA 4 wins on size, quiet operation and espresso quality for its footprint.

A full-size machine holds more and doses more per brew, but takes more space.

A capsule machine is similar in size, but costs more per cup and can't match fresh-ground beans.

The ENA 4 is the small-space choice for real espresso.

The ENA 4 in full: small display, simple buttons and dual coffee spouts.

Other Jura machines I tested

If you need a hot water spout for americanos and tea, the Jura E4 is the better black-coffee pick.

The Jura C3 is another compact, simple option that sticks to black coffee.

Jura ENA 4 specifications

From manufacturer data and my own testing.

How I tested and scored the Jura ENA 4

For four weeks, I used the Jura ENA 4 as my everyday machine for single and double espressos, long coffee and pre-ground decaf.

I tested all three strength levels with several bean types, worked through the grind range and tracked how often the tank, hopper and grounds bin needed attention.

I followed the full care routine, including a filter change and a tablet cleaning cycle.

I then checked my notes against Jura's specifications and owner documentation.

• Espresso (8.6): sweetness, crema, body and consistency across bean types.
• Long coffee (7.8): flavor at mug sizes and the double-brew option.
• Ease of use (8.8): buttons, display, strength settings and setup.
• Cleaning (8.6): drip tray, grounds bin, tablet cleaning and filter changes.

The overall score of 8.3 is an editorial rating that reflects those four areas.
