Jura E4 vs E6: black coffee only or milk drinks?

E4 vs E6 at a glance

Head to head

The better result in each row is marked, based on my testing and the manufacturer specs. Rows where the two machines are level have no winner.

Keep in mind that the tally is not my verdict. Some rows matter far more than others, and which ones matter depends on what you drink.

What the E4 and E6 have in common

These two are closer than almost any other pair in Jura’s range, and that makes the decision unusually clear.

Both are fully automatic bean-to-cup machines with a full-size brew unit✕Brew unitThe part that compresses the ground coffee, holds it while water passes through and ejects the used puck. that takes 5 to 16 grams of coffee. At 16 grams, one pass holds a full double shot or a 12-ounce mug.

Both use the Pulse Extraction Process✕Pulse Extraction Process (P.E.P.)Instead of pushing water through the coffee in one steady stream, the machine sends it in short, rapid pulses. It helps short drinks like espresso extract more evenly., which pushes water through the coffee in short bursts, and both heat with a thermoblock that recovers quickly between drinks.

So the espresso engine is the same family. What you are choosing is the milk system, the controls and how each machine handles hot water.

If you know you will never froth milk, that already points to the E4. If you are unsure, read on.

Design, size and build

Side by side, they look like siblings.

The Jura E4 measures about 11 inches wide, 13.8 inches tall and 17.6 inches deep and weighs about 22 lb. Its front has a row of lit icons instead of a screen, with a separate hot water spout to one side.

The Jura E6 is about 11 by 13.8 by 17.3 inches and also about 22 lb. Its front has a color screen flanked by chunky buttons, two coffee spouts and a center outlet for milk and hot water.

The E4’s lit icons and separate hot water spout keep its front simple and uncluttered.

Both have glossy housings that wipe clean easily, and both felt solid with no flex in the panels. The E4 looks a little more old-fashioned, which some people will love and others will not.

The E6 needs space beside it for a milk carton or container, with the hose running to the center outlet. The E4 needs nothing beside it at all.

Our tip: Leave room beside the E6 for a milk container, because the hose runs from the center outlet to a glass or carton next to the machine.

The E4’s separate hot water spout sits off to the side, so you can fill a teapot without moving the drip tray. On the E6, hot water comes from the center outlet, and a tall teapot needs the tray removed.

Lit buttons vs a color screen

This is the second big difference, and it changes how the machines feel every day.

The Jura E4 has no display. You press lit icons for espresso, coffee and their doubles, and settings like strength and volume are programmed by holding buttons. Once set, it is the simplest machine you can own.

The Jura E6 has a color screen with physical buttons on both sides. You can show two large or four small drink icons per page, and switch off the text labels once you know them.

The E6 also has Smart Mode, which tracks your most-made drinks and moves them to the front. By the end of my first week, americano and espresso sat on page one.

On the E4, settings live in your memory. That is fine for one person with one routine, but trickier for a household with several.

The E6’s color screen and Smart Mode make it the easier machine for a shared home.

Our tip: On the E4, write your programmed volumes on a sticky note inside a cupboard door, so nobody has to remember them.

For one person with one routine, the E4’s lack of a screen never bothered me. For a household, the E6’s screen and Smart Mode meant nobody had to ask how to make their drink.

Grinder and dose

Both use Jura’s Professional Aroma Grinder with steel conical burrs✕Conical burrsTwo cone-shaped grinding parts, one inside the other. Beans are crushed between them, and the gap sets how fine the coffee is.. Both grind quickly, which limits heat and keeps aromas intact.

The E6’s grinder sits on rubber mounts with extra sound damping, and its dial has six settings. Setting 3 with the strongest level became my default for a medium-dark blend.

The E4’s grinder felt very similar in the cup. It was slightly louder, but neither machine was noisy enough to wake anyone.

Maximum dose per brew. Both make doubles and big mugs in one pass.

Because both take up to 16 grams, neither has to split a big drink into weak, partial extractions. That is one reason both make better big mugs than many compact machines.

Our tip: Only turn the grind dial while the grinder is running on either machine, so beans never jam the burrs.

Espresso quality

Espresso is a tie, and that is the best news in this comparison.

The Jura E4 pulled thick, sweet espresso with a dense, stable crema✕CremaThe golden, foamy layer on top of a fresh espresso. It forms when pressure pushes oils and gases out of the coffee.. With a medium-dark blend, I tasted cocoa and roasted nuts with a clean finish.

The Jura E6 matched it: a heavy body, thick crema, dark chocolate and toasted nuts. Each shot starts with a short pre-infusion✕Pre-infusionA short soak of the ground coffee before full pressure starts, so water flows through the puck evenly. before full pressure.

My espresso scores

My scores out of 10 for body, crema, flavor and consistency.

The E6 pulled espresso just as rich as the E4’s, from the same size brew unit.

If espresso is all you drink, you lose nothing by choosing the E4. The quality is the same.

I also tested lighter roasts on both. On a finer setting with the strongest level, both kept their body and crema, and the flavors were just as close as with darker beans.

With a very fresh bag, both machines produced the thick, tiger-striped crema that makes a Jura espresso look so appealing in a glass cup.

Americano and long coffee

Both make a proper americano✕AmericanoEspresso topped up with hot water. Done properly, the water is added separately instead of pushed through the coffee., which is espresso plus hot water added separately, not a whole cup pushed through the grounds.

On the Jura E4, you pull an espresso, then twist a switch to release hot water from the separate spout, up to about 10 ounces. It takes a few seconds and a little attention.

On the Jura E6, the americano is a one-touch drink. It pulls a concentrated espresso first, then adds hot water through a separate path, and you can change the ratio and save it.

The cup tasted the same from both. The difference is convenience: on the E6, I pressed one button and walked away. On the E4, I stood and twisted.

For long coffee pushed through the grounds, both made a softer, rounder cup that suited travel mugs.

Milk drinks: the deciding difference

The Jura E4 has no milk system at all. No frother, no steam wand, no milk drinks.

The Jura E6 draws milk through a silicone hose and froths it using the Venturi effect✕Venturi effectWhen steam rushes through a narrow channel, it creates suction. Jura frothers use it to pull milk up the hose and mix in air.. It makes a one-touch cappuccino, an espresso macchiato and a portion of milk foam.

The E6’s foam has one fixed texture, so there is no one-touch flat white or latte. I built lattes by pulling a double espresso and adding two portions of foam, which took under two minutes.

This is the one difference that should decide your choice, because almost everything else is shared.

The E6’s one-touch cappuccino is the one thing the E4 cannot make.

How each milk foamed on the E6

My ratings out of 10 for texture and stability.

If you own the E4 and want an occasional cappuccino, a separate handheld frother and the hot water spout will get you close. It is a workaround, not a replacement.

Hot water and tea

Both are good for tea, which is unusual in this class.

The Jura E4 has a separate hot water spout, released with a manual twist switch. It gives a clean stream that never touches the coffee path, up to about 10 ounces.

The Jura E6 offers three hot water temperatures. Low suits green and white tea, medium suits herbal, and high handles black tea. It also comes with a pure hot water spout that swaps in for the milk spout, so tea never picks up milk traces.

Our tip: Fit the E6’s hot water spout whenever you make tea, so you get a clean, splash-free stream with no trace of milk.

In practice, the E4’s spout is great for a mug of tea or a teapot. The E6’s three temperatures are better if someone in the house drinks delicate green or white tea every day, because the low setting keeps the leaves from turning bitter.

Cleaning and upkeep

The E4 is the easiest Jura to clean that I have tested, simply because it has no milk system.

Both rinse their coffee paths on switching on and off, both have fixed brew units cleaned with a tablet when prompted, and both count down to filter changes and descaling✕DescalingRunning a mild acid through the machine to dissolve the mineral scale that hard water leaves in the heater and pipes. cycles. The E4 recognizes the CLEARYL Smart+✕CLEARYL Smart+ filterJura’s water filter cartridge. It sits in the tank and removes minerals and off-flavors, so the machine needs descaling far less often. automatically.

The E6 adds the milk side. It prompts a rinse after milk drinks, needs a weekly deep milk clean of under four minutes and a new silicone hose every three months.

My daily hands-on cleaning time

My estimate of hands-on time, not counting automatic rinses.

If you buy the E6 and only make black coffee, its cleaning is the same as the E4’s. The extra work only comes with the milk drinks.

Over a month, that came to roughly fifteen extra minutes of milk-related cleaning on the E6. For a weekly cappuccino drinker, that is a fair trade. For a household that never touches milk, it would be wasted effort.

Daily use and noise

My mornings with both settled into a quick rhythm. Switch on, let it rinse, make an americano. From button to cup took about a minute on each.

The E6 felt slightly faster for americanos, because it is one press. The E4 felt slightly faster for espresso, because there is nothing to scroll.

On weekends, the E6’s one-touch cappuccinos made it the family favorite. On the E4, the milk drinkers in my house had to do without.

Both are fairly quiet. The E6’s rubber-mounted grinder was the quieter of the two, with a low, short burst rather than a whine.

For a black-coffee morning, the E4 is about as simple as a bean-to-cup machine gets.

Which suits which household

During my test, both served the same three people: an espresso drinker, an americano drinker and someone who wants a cappuccino on Sundays.

The Jura E4 made the first two very happy. The cappuccino drinker went without, or used a handheld frother.

The Jura E6 made all three happy, and its Smart Mode kept the americano at the front of the menu.

The test is simple. If every person in your home drinks black coffee or tea, the E4 is all you need. If even one person likes milk drinks, the E6 avoids a daily compromise.

One more thing worth knowing: guests found the E6 easier. On the E4, I had to explain which lit icon did what and how to twist the hot water switch. On the E6, the icons and labels explained themselves.

What a full day of drinks looked like

To compare them fairly, I logged every drink each machine made on an ordinary Saturday with three adults in the house.

The E4 made nine drinks: four espressos, three americanos and two green teas. It needed no refills, and I emptied the tray once in the evening.

The E6 made twelve drinks: the same nine, plus three cappuccinos that simply would not have happened on the E4. It needed one milk rinse after each cappuccino round and still no water refill.

One Saturday, three adults, each machine on a different weekend.

That is the whole comparison in one day. The E6 did not make the black coffee better. It made room for the milk drinker, and asked for two extra minutes of cleaning in return.

Our tip: If you are torn, count how many milk drinks your household had at cafés last month, because that is roughly how often the E6’s milk system would earn its place.

Is the step up to the E6 worth it?

The step from E4 to E6 buys you three things: milk drinks, a color screen and better tea water.

It does not buy better espresso. Both made the same shot in my tests, from the same size brew unit.

In my reviews, the E4 scored 8.5 overall and the E6 8.4. The E4 scored higher for ease of use and cleaning, the E6 higher for versatility.

Where each scores higher, my scores

My scores out of 10 from my single reviews.

If you are sure you will never want milk, the E4 is the better machine for you. If you are not sure, the E6 keeps your options open at the cost of a little extra cleaning.

What I would change on each

On the Jura E4, I would replace the manual hot water switch with a button, and add a small display so you can see your settings instead of remembering them.

On the Jura E6, I would add a foam texture setting for a one-touch flat white, user profiles for shared homes and a stainless milk container instead of a hose in a carton.

None of these are deal-breakers. They are the small things that showed up after weeks of daily use.

My four weeks with both machines

Living with each machine for a month showed things a quick test never does.

Week one: dialing in

Setup was nearly identical. I tested my water hardness, fitted the filter and ran three drinks before judging anything. By day three, both were on a fine setting with the strongest level.

Week two: americanos

The E6’s one-touch americano took over my mornings. On the E4, I made the same drink with the twist switch, and after a few days it became automatic.

Week three: the milk question

In week three, my partner started asking for cappuccinos. On the E6, that was one button. On the E4, it meant a handheld frother and a second gadget on the counter.

Week four: maintenance

The E4 asked for almost nothing beyond emptying the tray. The E6 asked for a deep milk clean, which took under four minutes.

By week four, the E4 had proven itself as the lowest-effort machine in my kitchen.

By the end of the month, I understood both machines completely. The E4 is for people who know exactly what they drink. The E6 is for people who want a little room to change their mind.

Beans, water and supplies

Use fresh whole beans within a few weeks of the roast date on both. Avoid very oily or flavored beans, which can clog the grinder.

Medium and medium-dark roasts worked best on both for espresso and americanos. Lighter roasts did well on a finer setting at the strongest level.

Fill the tanks with fresh, cold water daily, use the filter if your water is moderately hard and skip distilled water.

Our tip: Buy beans you can finish within three weeks, because both grinders show off fresh coffee far better than stale.

Common mistakes to avoid

All of these become habits within a week.

Real-life scenarios

Specs only go so far. These are the situations where one machine clearly pulled ahead during my testing.

Lived with side by side, the E6 was the more flexible machine and the E4 the simpler one.

My scorecard

These are my own scores out of 10. The first four come from my single reviews of each machine, and I added two rows that decide this matchup.

Jura E4

Jura E6

Overall, I rate the E4 8.5 and the E6 8.4. The E4 is the purer black coffee machine; the E6 adds milk without giving up any espresso quality.

Which one should you buy?

It comes down to milk. If nobody ever wants a cappuccino, buy the E4. If anyone does, buy the E6.

For homes where even one person likes milk drinks, the E6 avoids a daily compromise.

Jura E4 vs E6 specifications

From manufacturer specifications and my own testing.

How I tested and compared them

I used each machine as my everyday coffee maker for four weeks, making espresso, long coffee, americanos and tea water, plus cappuccinos on the E6.

I tested every strength level, worked through the grind settings, programmed americano ratios and timed my daily cleaning.

I then compared my notes with Jura’s specifications, owner documentation and published test data.

• Coffee: dose, crema, body and consistency.
• Milk: foam texture, temperature and drink range.
• Workflow: controls, menus and daily routine.
• Ownership: noise, cleaning, water care and footprint.
