R Nine One is made for the professional home barista as well as for smaller establishments that want to serve really good coffee. Ergonomically designed steam wand with two holes provides really strong pressure on the steam. The milk is ready within seconds just like in commercial espresso machines.
Rocket Espresso R Nine One Edizione Speciale is a well-designed professional espresso machine that looks really stylish both in a small café and at home in the kitchen. This machine has a unique design and capacity for its size. The espresso machine has a built-in water tank but can also be connected to water and drainage.
Perhaps the most prominent specification that makes R Nine One an exceptional espresso machine is the brewing profiles. The ability to customize 5 unique brewing profiles allows for experimentation with almost everything for a long time. Within its brewing profiles, one can set 5 different parameters, meaning that one can set 5 different pressure and time settings in the same brew. Thus, About if one wanted to imitate a lever machine (an espresso machine that manually creates pressure by pulling down a vertical lever), one could program a profile so that for example in (1) 5 seconds running at 12 bar, (2) 6 seconds running at 11 bar, (3) 4 seconds running at 10 bar, (4) 4 seconds running at 9 bar, and finishing with (5) running at 8 bar for 6 seconds. Here, one has chosen to change the pressure and time 5 times, which is the maximum number. The pressure can be set between 0.1–12 bar. Nowadays, it is common to want to perform a so-called pre-infusion, which means soaking the coffee a bit before starting the actual brewing. Some claim that this makes a significant difference while others assert that it is hardly noticeable. Why not create two different profiles, one using pre-infusion and the other brewing in the traditional way? Experiment yourself and find your own answer.
All these settings can be easily found in the digital display on Rocket Espresso R Nine One. Page 2 of the menu shows a graph symbol in the bottom right corner; click on this to change the profiles. The left column indicates time and the right indicates pressure. Be sure to read the accompanying manual to see exactly how everything is set up.
Once you have set up your profile and brewing, a graph on the digital display will continuously show the pressure and time. For the crazy coffee lover, this is an awesome experience that allows for absolute perfection. Just look at the curve and assess About if something could be improved for next time. Not only does it look cool, it also helps quite a lot.
Rocket Espresso R Nine One is equipped with a water-filled brewing group, which essentially means that the flow between the group and the boiler is continuous. This means that the temperature is always the same, resulting in incredibly consistent cup-to-cup results. R Nine One is also equipped with a volumetric permanent magnet pump. This means a quieter, more stable brewing of your espresso.
Not only can you make really good coffee with the R Nine One Edizione Speciale, it is also very practical with its programmable on-off function. Within a 24-hour span, you can set it to turn off and on twice. This means that the coffee machine can be ready for use when you get up in the morning and are in dire need of coffee. Then it turns off just in time for when you go to work, only to turn on again so that the evening's coffee after dinner is also excellent. And during the night, it is turned off to save energy and thus help the environment.
The new steam system is equipped with a pressure sensor that makes a big difference for the barista who wants to produce many perfect cups in a row. The previous NTC temperature sensor that earlier models had works so that when the barista opens the steam, it takes up to 15 seconds before a noticeable temperature difference can be detected by the sensor. Once it detects a difference, it signals the system to turn on the element to maintain the heat in the boiler and thus the pressure. This means that a certain uneven pressure may occur due to the time delay. The new pressure sensor sends a signal About pressure change immediately when the barista opens the steam. At this moment, the sensor ensures that the system is aware of this and turns on the element immediately. This makes the steam pressure smoother than ever, and the hard-working barista never has to worry about a certain difference occurring. In short, the older one is a temperature sensor, and the new one is a pressure sensor, which increases temperature stability when frothing milk.
The accompanying R Nine One Edizione Speciale comes with a single handle, a double handle, a naked filter handle, a tamper, a cleaning brush, a blind filter, and a water connection hose.
