When I said I wanted to give the Z6 a winner title from the head-to-head comparison between Jura J6 vs Z6, I was not biased.
The Z6 is something for all coffee lovers who need a coffee maker to make quality espresso and meet high demands. It allows users to make over 21 fully programmable drinks at the press of a button. Its intuitive touch screen uses AI to put the most commonly made beverages on the home screen.
The J6 is also a powerful machine that has many cutting-edge features. Not only does it create great coffee, but it also holds highly technical components. So what made it lose in this battle? Let’s explore!

Jura J6 vs Z6: Key Differences
The Z6 wins against the J6 (4-1). The former produces consistently excellent flavor, and the better milk temperature captured my heart. Moreover, its larger water tank (81 oz) makes this machine ideal for both home use and commercial use.
Espresso Flavor

Winner: Jura Z6
Grinder
When reviewing any automatic coffee machine, I would look into the grinder first, as it plays a critical role in the overall espresso experience.
The conical steel burr grinder (Aroma G3) comes with almost all Jura machines, and the same goes for both the Jura J6 vs Z6. After two months since I tested these machines, I am still satisfied with this Aroma G3 grinder, as I haven’t gone through jams or anything similar.
Honestly, I prefer the ceramic grinder as it doesn’t overheat and risk burning the beans, but the Aroma G3 still is a fine setup. It can grind up the coffee beans lightning fast with angled blades that ensure precise extraction of flavors. Moreover, combined with P.E.P (Pulse Extraction Process) technology, this grinder guarantees your espresso has the best aroma.
So what is P.E.P technology? It results from a passion for great coffee and months of painstaking research. It forces hot water through the ground coffee at short and precise intervals to end up with the best flavor and aroma possible.
Heating System
Both machines share a single Thermoblock, meaning they take around 10 seconds to heat up for milk drinks. So these models may not be your best bet if you entertain guests frequently or want to make high volumes of beverages quickly. In this case, consider a model with double Thermoblocks.
The coffee temperature of both machines isn’t the hottest, ranging from around 180 to 185 °F. But, I think the Z6 delivers higher milk temperature, ensuring the final milk-based beverage is not too cool. Meanwhile, the J6 gives warm espresso, not hot enough to satisfy gourmets.
Milk System
Winner: Jura Z6
The first thing that came to my mind after testing the milk system of these machines is they aren’t ideal for making microfoam. Hence, dry and airy milk foam, no doubt, isn’t common in those models.
But Jura Z6 and J6 are ideal for those who love flat white and latte as they froth creamy, thick, and full-bodied foam. But, as mentioned above, the milk temperature of the Z6 is higher, making it the victor in this category.
They don’t come with a carafe for milk, and you will have to buy it separately. I’m a bit disappointed by this because, with more than $2500 on a machine, it should come with everything essentials.
Utilities

Winner: Draw
Control Panel
Without a touchscreen like the more modern Jura models, the E8 and the J6 feature a TFT display, push button, and rotary switch.
If you ask me if I like these TFT displays, the answer is No. But that doesn’t mean they are not convenient. It’s just about personal preference.
Remote Control
Both gargets are equipped with Smart Connect, allowing you to operate them with J.O.E (the free Jura Operating Experience) application. Having house guests? Make them raise their eyebrows by creating coffee from your phone.
Size, Wattages, And Capacity
The winner: Jura Z6
Size
The Z6 is a large machine, measuring 32cm x 37.5cm x 45cm and weighing 25.6 pounds. It is not surprising that this machine is designed to meet high demand.
So if your kitchen is small or you have small clearance between countertops and cabinets or limited counter space, finding a space for it is difficult. But it is still considerably smaller than many industrial machines, although it can still meet industrial-like demand.
The J6 is slightly smaller, measuring 28.5 x 34.2 x 43.3 cm and weighing 24 lbs. It can also meet high demand without a giant industrial machine appearance. It is an ideal machine for any kitchen, but I recommend researching where to put it ahead of time.
CAPACITY AND WATTAGES
The Z6’s water tank and bean container capacity is 84 ounces and 10 ounces, respectively. It is safe to say that this model can store more ounces of water than any Jura machine. It allows you to brew at least 16 cups of espresso before running out of water and coffee beans.
On the flip side, the Jura J6 is equipped with a 71-ounce water tank and an 8.8-ounce bean hopper. I recommend this model for home use as it may be too small for office settings or self-service bars.
Besides that, the engines of both gadgets are quite strong. With 1450 watts and double spouts, you won’t waste too much time getting your delicious coffee.
Because of the large water tank, I totally lean toward the Z6 side.
Jura J6 vs Z6: Similarities
Cleaning And Maintain
The cleaning process for both Jura J6 and Z6 is straightforward and is one of the reasons why these coffee machines are worth the price.
There’s no question that these super-automatic models require more maintenance than average drip-brew machines, but you won’t find them particularly bothersome or challenging.
But, no matter how automatic these machines are, handiwork is always involved. The good news is that all the things that need to be cleaned manually, such as the brew unit, drip tray, milk tube, grinder, and dregs box, are easy to access.
Compatible With Pre-ground Coffee
This feature is no longer something out of the ordinary and is found in most super-automatic machines. The pre-ground slot can be found on top of the machines and is located next to or inside the bypass doser.
You can put any type of coffee ground into this slot, and it also is where you can put the cleaning tablet before cleaning your machine thoroughly.

I am Ralph Mason and I am a passionate coffee drinker. I worked as a barista for a few years and since 2012 I have been trying to convince as many people as possible of good coffee.
I started writing on the barista blog on RepublikCoffeeBar in 2018. It was a pure hobby site and I tested coffee products like coffee machines, beans, mug, and other accessories. After the first year, my blog is becoming a well-known coffee site with about 100 thousand visits per month.
In 2019 I decided to focus on RepublikCoffeeBar only. I became a full-time coffee blogger and was declared crazy by many.
