Quality: Meet technology with the Rocket Espresso R Nine One. Built with the utmost in home espresso in-mind, the R Nine One builds from the design of Rocket Espresso's commercial brethren with a saturated group, stainless brew and service boilers, and programmable dosing. The R Nine One adds to this formidable foundation with both manual and programmable pressure profiling—giving you 5 profiles for any coffee recipe imaginable. Profiles are set through the R Nine One's color touchscreen, or by hand with the group-mounted control knob. Other class-leading features include power scheduling to preheat your machine before use, PID controller temp management, and a full-stainless case and frame. If you're looking for the next step in Italian espresso machines, the R Nine One is hard to beat.

- Saturated Group: A fully-circulated water path keeps the group head temp-synced with the brew boiler, bringing added consistency to your shots.
- Pressure Profiling: Design shot profiles for long preinfusions or declining pressure—and anything in between. The R Nine One can be programmed for 5 pressure profiles or used manually.
- PID Controller: Electronic control over temperature provides easy adjustments for different coffees and intrashot stability.
- Volumetric Dosing: Program shot length by the milliliter for each pressure profile.
- Auto-on Timer: Set your R Nine One to wake up before you do! Program up to 2 heat cycles every day of the week.

- Profiling Options: Pressure profiling gives enthusiasts unprecedented ability to play with shot flavor—from recreating classic lever machine shots to pour over-like low pressure cups of coffee.
- Temp Stability: A PID-controlled brew boiler and a temp-regulated group make for great shot consistency.
- Steam Pressure: The ample-sized steam boiler offers good pressure and recovery between drinks—even on common 15-amp power.
- Touchscreen UI: While the R9 One's touchscreen is necessary for the crazy amount of customization offered, the interface seems dated and clunky compared to other machines on the market.
- Read the Manual: Make sure to keep the manual handy! The amount of programming packed into the R9 can be a little overwhelming.
