The Rocket R9 ONE (Dual Boiler) is Rocket's top of the range dual boiler pressure profiling machine. It's the peak of their research & development products to date, offering an amazing level of control over the espresso extraction process. As well as being a dual boiler it boasts a fully saturated group-head, cool to touch steam wand, slayer style steam activation arm, touch screen controls and paddle activated shots. It also has the capacity of choosing between reservoir or main water supply.
Who is it suited too?
The R NINE ONE is geared towards those who want ultimate control over every variable in the espresso making process, with zero compromise. This includes precision control over the temperature in both service and brew boilers plus the pressure and time of the extraction. Further, it is designed to offer record and re-play functionality over the shot time and pressure(including pre-infusion). For those who like to experiment with the espresso making process and have the ability to play back that 'perfect shot' it really is about as good as it gets.
What is the build quality like?
The R NINE ONE is built like a tank. It weighs around 45KG, so it's reassuringly heavy. The unit is housed around a solid stainless steel chassis, so it's very stable. The attention to detail is exceptional, with excellent finish both inside and outside the machine. It has beautiful clean lines across it's production, which give it a luxury feel.
How do I use it?
Once the reservoir is filled up, it takes around 12 mins to get fully up to temperature (20 if you want to see full heat transfer across the entire machine). It's a manual activated machine, with shots triggered by using the paddle on top of the group cap.
It has the capacity to add pre-infusion and change the pressure of each shot across a series of points during the extraction process, which appears as a graph on the touch screen as you carry out the extraction. If you decide that the shot profile that you just created was a good one, you can save that action in one of the 5 recording slots and reply it on demand.
You can use the machine in fully manual mode if you wish, or replay the shots that you have recorded. If you replay recordings, you do so by choosing the recording you want, then activate it by moving the paddle slightly to the right to start it, then watch the recording carry out the entire process for you.
The touch screen:
Once inside the menu, you can access the shot timer, the recorded profiles (or empty banks to record too), the PID settings for both boilers, the switch control between the reservoir and the main water connection and the pressure profiling / pre-infusion settings.
Other key features:
It has separate (cool to touch) steam wand for steaming milk and hot water tap for topping up black coffees.
It's a stand alone machine, so you need a separate grinder to run alongside it (See HERE). We highly recommend a grinder that has 65mm burrs, as the R NINE ONE is capable of extracting amazing quality, but requires a good quality grinder that is capable of providing high quality grind that can match the R NINE ONE's performance.
