Jura ENA 4 Review 2022: Diamonds Are Forever!

After working as a professional barista for many years, Arne Preuss founded Coffeeness.

If there’s one thing Jura excels at, it’s producing minimalist espresso machines, and the Jura ENA 4 is pretty solid proof of that. Jura might not mind skipping the milk system, but I don’t intend to leave out anything in this Jura ENA 4 review. 

Jura ENA 4 Review Overview with Arne

If there’s one thing Jura excels at, it’s producing minimalist espresso machines, and the Jura ENA 4 is pretty solid proof of that. Jura might not mind skipping the milk system, but I don’t intend to leave out anything in this Jura ENA 4 review. 

If you’re already familiar with the Jura A1, then the ENA 4 will probably look like its smaller, more compact sibling. Aesthetically, you might not even be able to tell them apart  – aside from the ENA 4’s faux diamond water tank, that is. Don’t worry, I’ll be getting into that later.

Of course, the additional $200 that puts the ENA 4 at $894.95 is right about where the family resemblance ends.

Jura ENA 4 Coffee Machine Overview

As far as looks go, the sleek exterior on the ENA 4 is almost stylish enough to make me forget it’s just black plastic. It’s not as eye-catching as the glossy finish on the A1. Still, it doesn’t hurt the minimalist vibe that Jura is trying to achieve. 

You could probably argue that Jura takes its minimalistic approach too far by leaving out the milk system, but that’s up to interpretation. Considering the price point of this machine, it’s definitely a bold move. If you’re someone who loves black coffee and wants an espresso machine that excels at making it, the ENA 4 might just be your perfect match. 

However, for coffee drinkers that always need a latte macchiato or cappuccino option, I don’t see it working out long-term. There are far too many other machines in the sea that’ll treat you right (and contain milk systems). Check out my super automatic espresso machine guide 2022 if you need proof!

Anyway, if the absence of a milk system hasn’t scared you off, keep reading my Jura ENA 4 review. 

Jura ENA 4 Features

I’ve mentioned that the A1 and ENA 4 feel like twins, and that comparison goes beyond their looks. Feature-wise, these two aren’t identical. Still, it’d be hard to tell them apart in a lineup. With that in mind, I could just stop my Jura ENA 4 review here and direct you to my A1 review, but I won’t. Despite sharing a lot of the same specs, these two aren’t complete copycats. 


I could tell you that the ENA 4 just comes in white and black, but instead, I’ll use the same fancy vocabulary Jura does. With this machine, you get your pick between Metropolitan Black and Nordic White. I’m not sure what exactly makes black “Metropolitan,” but it certainly does sound sophisticated! 

Considering its minimalist approach to fully automatics, I’m not surprised that Jura only offers two color choices. Between the two, I think the white one pairs better with the crystal water tank, but that’s just my ‘ole humble opinion. Either way, it’s hard to argue with the classics. Both black and white go with almost any kitchen decor. 


Bigger is not always better, especially when you don’t have a palatial kitchen. The ENA 4 is far from the most compact super automatic I’ve seen, but it’s smaller than you might think. In fact, Jura totes this as their most compact machine. 

It doesn’t look completely compact, but I think most of that has to do with the ENA 4’s overall design. It’s got the same sharp geometric angles that most of Jura’s products do, but it’s not as sleek or glossy. 

A machine like the A1 stuffs most of its important components under the hood. However, with that round water tank stuck to its side, the ENA 4 doesn’t seem as worried about saving space. Still, this espresso machine shouldn’t end up hogging too much real estate on your kitchen counter. 

Jura compares the size of the machine to the length and width of loose-leaf paper. So, if you’ve got room for a sheet of paper on your counter, then you’ve also got space for the ENA 4! 

User Interface

Jura ENA 4 User Interface.

If there’s one thing that a fully automatic like this can brag about, it’s being easy to use. There’s no tampering with milk foam settings or fiddling with a steam wand. In fact, it only takes the press of a few buttons to have liquid gold flowing into your cup. Or, as close to liquid gold as black coffee can get. 

The ENA 4 is no exception. The barebones digital interface is impossible to miss on the front of the machine. There are only four buttons, and while that may seem limiting, they offer more versatility than you might think.  

One button allows you to adjust the strength of your coffee, measured by coffee bean symbols that flash across the screen. Three coffee beans is the strongest setting, translating to a higher dose of ground coffee.

Another button allows you to pick between brewed coffee and espresso, and there are settings that allow you to tinker with the amount of coffee dispensed. The most the machine will dispense at once is 8 ounces (237 milliliters). That might be a bit of a letdown if you’re someone who likes to brew eight or twelve cups at once. Then again, this isn’t your grandma’s drip coffee maker by any means. 

Now, if you’re looking to make specialty drinks or fiddle with advanced settings, you can pair the ENA 4 with the Jura app on your smartphone. Using the app is an entirely different conversation, so I’ll cover that later in my Jura ENA 4 review. 

Aroma G3 Grinder

Jura ENA 4 Coffee Machine Grinder.

The Jura ENA 4 comes equipped with the manufacturer’s awesome Aroma G3 grinder. 

The design of the G3 grinder allows for a lot of variation of grind size, and I’d really expect nothing less from Jura. It’s another way they’ve packed countless adjustment settings into a minimalist package.  

One important thing to note is that you should only adjust grind settings while the grinder is actively working. Sort of like riding a bike  – you can only switch gears when the bike is already in motion. 

There aren’t a lot of bells and whistles on the Aroma G3 grinder, but it handles everything it needs to. It’s hard to argue with a grinder that’s efficient and won’t wake the entire house up in the morning. Plus, the bean hopper lid is clear, so you can see the magic at work whenever you want. 

As far as capacity goes, you can store up to 4.4 ounces (124 grams) of your favorite coffee beans in the hopper. 

Pre Ground Coffee

Jura ENA 4 Slot for Pre Ground Coffee.

While I’m on the subject of coffee beans, let’s talk about pre ground coffee. These days, most manufacturers include a bypass doser for ground coffee. I suppose that’s good for preparing the odd decaf drink, but I find that ground coffee chutes tend to clog up too easily. 

The ENA 4 does include a separate slot for adding pre ground coffee, so you don’t always have to brew with whole beans. Of course, you’ll probably want to stick with fresh beans most of the time. Still, it never hurts to have the option for an evening decaf coffee

Water Reservoir

The Beautiful Water Tank of the Jura ENA 4.

Okay, okay, it’s time to talk about the ENA 4’s crowning jewel  – the faux diamond cylindrical water tank. It might come as a surprise considering the price, but this baby isn’t a real diamond. Still, Jura has made a big point of showing it off. Rather than stick it under the lid like most water tanks, they’ve connected it to the side

Jura says the inspiration for the water reservoir comes from those fancy crystal carafes you store alcohol in. Now, I’m all for making Irish coffee. In this case, though, I don’t think adding whiskey or bourbon to the water reservoir is going to work out well. It’s probably best we stick to water and keep the alcohol in an actual crystal carafe. 

Jokes aside, I’ve got mixed feelings about the water tank. While I can’t deny how pretty the reservoir looks, I’m not sure it justifies the machine’s high price tag. If you’re someone who’s all about aesthetics, the crystal-like tank might be worth the extra dough. It’s probably the most unique water tank I’ve ever seen on a coffee maker. Anyway, the manufacturer liked it enough to stick it on the Jura ENA 8 too. 

Functionally, the tank works just like any other water reservoir. You can pop the top open to fill it up or just remove it  – dealer’s choice. It’s still small enough to fit in one hand, so that’s a plus.

Intelligent Water System – I.W.S.

Jura ENA 4 Intelligent Water System.

While we’re on the subject of water tanks, I don’t want to gloss over the Intelligent Water System (I.W.S.). Once again, Jura tries to impress us with important-sounding features. By the sound of that name, you’d think it could do basic math or read you a book while it brews your espresso. I mean, I can’t be the only one who’s been waiting for a coffee manufacturer to roll out those features!

However, at its core, the I.W.S. is a clever feature that notifies the system when you’ve changed the water filter. With some super automatics, you have to go through the trouble of recalibrating the coffee machine whenever you change the filter. 

Here, there’s no need for programming new water filters in, and Jura is confident you won’t have to worry about regular descaling. Personally, I take that last part with a large grain of salt.

Pulse Extraction Process – P.E.P.

Like the Intelligent Water System, the Pulse Extraction Process (P.E.P.) is another feature you’ll find on a lot of Jura coffee machines. In fact, I’d go so far as to say P.E.P. is Jura’s bread and butter. It’s the main reason why this machine excels at making plain espresso. 

Essentially, the P.E.P. works by soaking the coffee grounds with short bursts of water rather than with a constant flow. So, you get maximum extraction and flavor, regardless of the drink you’re pumping out. Some super automatics might have their own versions of this feature, but none are as successful and effective as Jura’s brewing technology. 

Spout Height

Here’s some good news. If you’re worried that your travel mug won’t fit comfortably under the ENA 4 spout, you can give a sigh of relief. While the standard spout height is set low to accommodate espresso cups, you can adjust it with a single push

It’s a seamless process, and a lot easier than trying to remove the drip tray every time you want a little extra room. 

Specialty Coffees

Jura ENA 4 Coffee Maker Specialty Coffees.

With a machine that specializes in black coffee and espresso, I can’t be too surprised that the ENA 4 is limited in the specialty drink department. There’s no espresso macchiato, cappuccino or most of your other coffee shop favorites. 

Besides a standard espresso shot and brewed coffee, the ENA 4 does allow you to brew two shots back to back or a long shot. These customizations don’t really fall under the specialty coffee umbrella, but it’s about as fancy as the ENA 4 gets. 


I said I’d come back to smartphone compatibility in my Jura ENA 4 review, didn’t I? If you want to get the most out of your ENA 4, Jura does have an app you can sync up to your automatic. The Swiss brand says smartphone connectivity isn’t an essential feature, which may explain why you have to buy the WiFi Connect separately. 

Personally, Jura and I may have different definitions of essential. Sure, you don’t need to sync the coffee maker up to your phone to operate. However, there are also certain features and settings you won’t be able to access unless you’re controlling the coffee maker remotely. 

It’s also just a lot easier to navigate the machine’s settings in the app versus the user interface. The ENA 4’s display interface talks in flashing coffee bean symbols, but the app uses English. 


While we’re on the subject of smartphones, I don’t want to miss talking about another one of the ENA 4’s add-ons: Siri. That’s right, I’m referring to everyone’s favorite virtual assistant. If you thought controlling a fully automatic from your phone was easy, using Siri simplifies the coffee making equation even more. 

Once you’ve got the WiFi Connect plugged into your machine and you’ve downloaded the Jura JOE app, you should be able to control your ENA 4 with voice command. It’s sort of like having your own personal barista in your pocket  – although this one won’t try to make small talk about the weather. 

How to Use the Jura ENA 4 Coffee Machine

If there’s one thing I’ll compliment Jura on, it’s that you’ll probably never touch the ENA 4 user manual. Unless you’re trying to fiddle with advanced settings or don’t have access to the app, the ENA 4 should be incredibly easy to use. No rocket science involved here, folks. 

  • As with any fully automatic machine, you’ll need to fill up the bean hopper and the water reservoir first. 
  • Turn on the machine and place your cup under the spout. If you’re using a larger cup or glass, you can adjust the dispensing spout upwards. Pro tip: if you’re making espresso, try running your cup under a little hot water. A warm cup makes all the difference. 
  • Here’s where you’ll start messing with the user interface. On the far right, there’s a button with a coffee bean symbol. This controls the strength of your drink, as well as whether you’ll be using pre ground coffee. Since you have three strength settings, you can use the coffee bean button to cycle through them. 
  • To dispense your espresso, press the button with the demitasse cup icon until the coffee beans on the screen start flashing. This is where the machine enters its programming mode and allows you to change the volume of coffee to be dispensed. 
  • You can stick with a standard shot, but the machine will dispense up to 8 ounces (237 milliliters) of coffee or espresso at once. Just press the button again when you’ve got the desired amount. Next time, the machine will remember your settings, which is a nice feature. 

That’s all there is to it! It’s so simple I’d say you could trust a well-trained dog to do it. You probably shouldn’t for safety reasons, but you see my point. 

Jura ENA 4 Coffee Machine Cleaning

Jura ENA 4 coffee maker cleaning.

I know cleaning and descaling is everyone’s favorite part of owning a coffee machine. Just kidding. Still, rest assured; the ENA 4 is far from high-maintenance. There’s a separate compartment hidden on the side of the machine that holds your used coffee grounds. I recommend emptying it after every use and giving the compartment a quick rinse afterward. 

I’ve mentioned that the Intelligent Water System eliminates the need for regular descaling, but that doesn’t mean you’ll never have to do it. You won’t need to descale the coffee machine as often as some fully automatics, but you shouldn’t ignore this step of the process completely. For those deep cleans that happen once in a blue moon, I’ll refer you to Jura’s user manual. 

That’s about as gritty as cleaning the ENA 4 gets. You’ll still need to regularly empty the drip tray and wipe down the exterior of the machine, but a damp cloth and a mild cleaner will get the job done. 

As with all Jura coffee machines, the brewing unit can’t be removed. That means you’ll need to use Jura cleaning tablets to rinse the coffee circuit. Don’t worry, though – the machine will let you know when that’s necessary.

I’m sure Jura includes this somewhere in the fine print, but I’ll leave a disclaimer here too. This coffee machine isn’t safe for the dishwasher and you should avoid submerging it in water. 

Jura ENA 4 Accessories

Just because Jura has adopted a minimalist philosophy with this coffee maker doesn’t mean it’s completely abandoned the idea of accessories. You’ll have to shell out some extra dough, but here are some ways you can enhance your ENA 4. 

Cup Warmer

If you’re not prewarming your espresso cups, I’d argue that you’re not getting the full effect of your morning brew. Now, before you tell me I’m being dramatic, hear me out! Nothing is going to cool your piping hot espresso down quicker than pouring it into cold porcelain or glass. 

It’s more than just simple heat loss too. The drastic temperature change is going to affect your coffee’s aroma, and who wants a subpar coffee experience? Not me! Anyway, that’s the science behind cup warmers  – which you’ll find included with plenty of coffee machines. Minus the ENA 4, of course. 

Fortunately, you can purchase a cup warmer tray separately. Take the Jura Cup Warmer, for instance. 

This little cup heater is compact enough to fit snugly against your ENA 4, and there are two heating elements to keep your demitasse cups toasty all day long. Of course, a more affordable solution is to heat your cups using warm water. Just saying.

Jura Espresso Glasses

We all know Jura is synonymous with elegance, so these nifty little espresso glasses are very on-brand. There aren’t any special features here, but glass espresso cups do have great heat retention properties. Combine that with a cup warmer and you’ve got the makings of an excellent coffee tasting experience on your hands. Or, in this case, on your tongue.

Jura ENA 4 vs Other Super Automatics

I know I’ve been gabbing about the ENA 4 for this entire article, but it’s time to add some other espresso machines into this Jura ENA 4 review. 

Jura ENA 4 vs Jura A1

I’ve done a lot of unofficial talking about how the ENA 4 measures up to the Jura A1, but now I’m on the record. Jura considers the ENA 4 to be a replacement for the A1, which may explain why there are limited differences between them. 

Costing $795.00, the A1 isn’t as compact, it’s missing that eye-catching water reservoir and it also doesn’t have the capacity for using pre ground coffee. That’s about it as far as differences go. 

Functionally, these two have the same grinder and are both single serve bean to cup machines. In my opinion, I appreciate the sleek design of the A1 more  – as well as its more affordable price tag. Unless you’re purely worried about looks, I’m not sure there are enough upgrades to warrant the $200 price jump.

Jura ENA 4 vs SMEG Fully Automatic Coffee Machine

I think SMEG is out to dethrone Jura as the bean to cup coffee machine queen, and its SMEG Fully Automatic Coffee Machine is proof of that. Full disclosure  – there are two versions of the SMEG Fully Automatic. One has a milk system and one doesn’t. In an effort to be truly fair, I’m talking about the second one here. 

The SMEG machine does lack smartphone capabilities, but it makes up for it with a simple user interface and ultra compact design. Seriously, it’s hard to find a super automatic as tiny as the SMEG bean to cup machine. At $849.95,  the SMEG offers a few more options for specialty drinks, but isn’t that much more versatile than the ENA 4. 

The biggest difference between these two is probably size and aesthetics, so you’ll have to judge which one looks prettier.

Jura ENA 4 vs Tchibo Coffee Machine

If you’ve already read my review of the Tchibo coffee machine, you’ll know I’ve got mixed feelings about the thing. Still, most of my issues have to do with the manufacturer. 

It’s hard to beat the full-bodied espresso that Jura is known for. However, as a budget espresso machine, the Tchibo has potential. Anyway, if you’re dead set on a coffee maker without a milk system, the Tchibo will be a lot kinder to your wallet. It’s not as compact or as eye-catching as the ENA 4, but it’s got adjustable settings and makes halfway decent espresso.

Verdict: Jura ENA 4 Coffee Machine

Jura ENA 4

What a beauty!

Beautiful and compact machine

High quality grinder

Easy to operate

Makes great espresso

Expensive for what you get

No milk frothing capabilities

Okay, moment of truth. I know I’ve given this coffee machine a bit of a hard time in my Jura ENA 4 review. Still, it’s hard to really diss anything that the Swiss manufacturer pumps out. Jura’s reputation for great, full bodied espresso is something to keep in mind when considering the ENA 4  – or any of its other super automatics. 

With that said, the ENA 4 is not a one-size-fits-all kind of coffee maker. It’ll fall flat for some coffee drinkers, yet hit the bullseye with a specific group. If you’re someone who loves straight espresso and wants a pretty coffee machine for guests to fawn over, the ENA 4 will be a perfect match. It’ll be hard to find another super automatic that makes black coffee as well or looks as gorgeous on your counter. 

However, if you’re ready to spread your figurative coffee-making wings and try new drinks, the ENA 4 probably won’t be versatile enough. The Jura ENA 4 is great at making espresso and black coffee. But beyond that, there’s not much to write home about. Lovers of milk based specialties shouldn’t have any trouble finding a machine that’s well within the same price point while offering more diversity. 

I hope you’ve enjoyed my Jura ENA 4 review. What do you think … should I take the plunge and buy this machine? I look forward to your comments!
