R Nine One Espresso machine

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

Please note that when choosing the wood option, the incorrect product image shows. We only sell the R NINE ONE with stainless side panels with a choice of the standard plastic handle set or the four different wooden options.

R Nine One is made for the professional home barista as well as for smaller servings that want to serve really good coffee. Ergonomically good steam knob with two holes gives really strong pressure on the steam. The milk is ready within seconds just like on commercial espresso machines.

Rocket Espresso R Nine One is a well-designed professional espresso machine that looks really nice both in the small cafe 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 sewage.

Perhaps the main specification that makes the R Nine One an espresso machine in a class of its own is the brewing profiles. The ability to customize 5 unique brew profiles allows you to experiment with almost anything for a long time. Within its brewing profiles, you can set 5 different parameters, which means that you can set 5 different pressure and time settings in the same brewing. In other words, About you would like to imitate a living machine (espresso machine that you manually create pressure by pulling down a vertical lever) so you can program a profile so that for example for (1) 5 seconds you run 12 bar, (2) 6 seconds you 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 they have therefore 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 do a so-called pre-infusion, which means that you soak the coffee a little before starting the actual brewing. Some claim that this makes a significant difference, while others claim that it is barely noticeable. Why not create two different profiles, one of which uses pre-infusion and the other brews in the traditional way? Try it yourself and find your own answer.

All these settings are 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 column indicates pressure. Please read the included manual to see exactly how everything is set up.

Once you have set your profile and are brewing, a graph on the digital display will show the pressure and time continuously. For the crazy coffee lover, this is an awesome experience that allows for absolute perfection. Just look at the curve and judge About something could be improved for next time. Not only does it look cool, it also helps quite a bit.

Rocket Espresso R Nine One is equipped with a water-filled brewing group, which basically means that the flow between the group and the boiler is continuous. This means that the temperature is always the same, which means that the results are incredibly even from cup to cup. The R Nine One is also equipped with a volumetric permanent magnet pump. This means a quieter, more stable brewing of yours espresso.

Not only can you make really good coffee on the 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 dire need of coffee. Then it is switched off in time until you go to work and then switched on so that the evening coffee after dinner is also excellent. And during the night it is switched off to save energy and thus 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 former NTC temperature sensor that previous models have had works so that when the barista opens the steam, it takes up to 15 seconds for a noticeable difference in temperature to be noticed by the sensor. Once it senses a difference, it signals the system to turn on the element to maintain the heat in the boiler and thus also the pressure. This means that some uneven pressure may occur given the time delay. The new pressure sensor sends a signal About pressure change immediately when the barista opens up the steam. At this moment, the sensor makes sure that the system finds out about this and turns on the element immediately. This means that the steam pressure is more even than ever and the hard-working barista never has to think about a certain difference. In short, the older one is a temperature sensor and the new one a pressure sensor, which increases temperature stability when frothing milk.

Included with the R Nine One comes a single handle, a double handle, a naked filter handle, a tamper, a cleaning brush, a blind strainer and a water connection hose.
