R Nine One from Rocket Espresso is designed by the Italian engineer Ennio Berti who aimed to achieve even more precise temperature stability so that each espresso would be perfect. With water-filled brew groups to promote temperature stability through PID controlled electronics in boilers made entirely of stainless steel, one can certainly say he succeeded.

More information
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 upper group with two holes provides really strong pressure on the brew. The milk is ready in a few seconds just like on espresso machines for commercial use.
Rocket Espresso R Nine One 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.
The perhaps foremost specification that makes R Nine One an exceptional espresso machine is the brew profiles. The ability to customize 5 unique brew profiles allows for experimentation with nearly everything for a long time. Within its brew profiles, one can set 5 different parameters, meaning that you can set 5 different pressure and time settings in the same brew. Thus, About if you would like to imitate a lever machine (an espresso machine where pressure is manually created by pulling down a vertical lever), you can program a profile so that for example in (1) 5 seconds you run 12 bar, (2) 6 seconds run 11 bar, (3) 4 seconds run 10 bar, (4) 4 seconds run 9 bar, and finish by running (5) 8 bar for 6 seconds. Here you have 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 this makes a significant difference while others argue 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 corner at the bottom right, click on this to change the profiles. The left column indicates time and the right indicates pressure. Please 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 amazing experience that enables absolute perfection. Just look at the curve and assess About if anything 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 brew group which basically 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 R Nine One, 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 2 times. This means that the coffee machine can be ready for use when you get up in the morning and are in great need of coffee. Then it turns off just in time for when you go to work, and then turns on so that the evening's coffee after dinner is also excellent. And during the night it is turned off to save energy and thereby 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 have had works such that when the barista opens the steam, it takes up to 15 seconds for a noticeable difference in temperature to 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 as well. This means that a certain uneven pressure can occur due to the delay. The new pressure sensor sends a signal About pressure change directly when the barista opens the steam. At this moment, the sensor ensures that the system picks this up 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.
Accompanying R Nine One comes a single portafilter, a double portafilter, a naked filter handle, a tamper, a cleaning brush, a blind filter, and a water connection hose.
