The improvements are quite a few, including the four selectable strength options that helps determine the dosage of the shots you want to brew between five and sixteen grams of coffee. If you want, you can easily tailor your experience with programmable pre-brewing, brew temperature and water volume. You can make the adjustments by using the rotary switch and the good news is that the machine will remember your preferences so you can brew the same delicious cup of coffee next time.
As a home barista, you need to master all the above techniques to get the right espresso. If you make a little mistake you compromise your shot. As a result, you’ll get an average shot. Even if you know what it takes to get your shot right, there is very little room for error. Failed shots are pretty common with beginner baristas. You probably noticed in coffee shops that the shot differs from barista to barista.
The first machine I received never worked correctly. The milk would not steam and the espresso would start to come out and then stop. Upon stopping a message would display on the screen asking to press a button to fill the pump. This would occur 2-3 times before an expresso could actually be made. I experimented with several different grind settings, coffee strength, water temperatures, etc, but with no success. The machine continued to pump a few drops of espresso, asking to refill the pump, and waste the previous grinds. I literally wasted 2-3 cans of Illy espresso without ever getting espresso. In addition, with each espresso cycle, a large amount of water would precede any espresso. For example on a 1oz shot, about 0.1oz would be water that didn't run through the coffee.
The Impressa Z6 employs Jura’s innovative Pulse Extraction Process brewing system. As opposed to a constant flow, water is instead pulsed through the grounds in short intervals that extract greater intensity and aroma while shortening the overall brew time. With P.E.P., espresso and ristretto can be prepared with greater clarity and flavor than ever before.
“My first impression was a great machine well built; the manual was more challenging than it should have been but not hard to follow. Once I got the machine set up it's been delivering consistently great coffee, the dry grounds it produces make cleaning easy, the display makes maintenance pretty self-explanatory, the operation is quiet, and it's an obvious improvement over my previous machine.
The Impressa’s control panel is based around a central colour display that’s used to guide you though the process, which helps to turn a maze of functions into an intuitive set of menus (or a carousel as Jura call it). The control of the menus is achieved by a ‘rotary switch’ located on top of the machine at the front, neatly sandwiched between the power and program buttons. The buttons either side of the screen vary in purpose, depending what’s on the screen at the time. in general though, the screen splits into four zones, with each button used to select the corresponding zone.
Of course, this is not all and you get a wide range of other impressive functions, such as ceramic valve technology, pre-ground option for decaf, 1-touch cappuccino system, large bean hopper with sensor and adjustable height brew spouts. Therefore, if you’re looking for the ultimate in espresso machines, then you certainly need to consider the Jura XS90 and experience how the perfect espresso shot actually tastes like.
