Overview
The Rocket R Nine One is the ultimate expression of Rocket Espresso engineering philosophy, combining dual boiler precision with true pressure profiling capability in a stunningly designed package. The defining feature is the proportional pressure paddle on the group head, which allows the barista to control pump pressure in real time during extraction — from zero to full pressure and everywhere in between. This enables complex pressure curves: gentle pre-infusion, ramp to 6 bars, peak at 9, and decline to finish — or any profile the barista can imagine. The dual boiler system with 580ml brew boiler and 1.8L steam boiler, both PID-controlled, ensures thermal stability while the pressure profiling opens entirely new flavor dimensions. The rotary pump provides the smooth, consistent power needed for reliable pressure control, and the machine can be plumbed for convenience. A touchscreen display shows real-time pressure, temperature, and shot time data. The R Nine One represents Rocket answer to the pressure profiling movement — implementing it within the traditional E61 framework rather than abandoning it. For the advanced home barista who wants to explore the full potential of espresso extraction while maintaining the beauty of Italian machine design, the R Nine One is without peer in the Rocket lineup.
The Rocket R Nine One comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction, pressure profiling for advanced shot manipulation, flow control for barista-level precision. It features a dual boiler boiler system made of stainless steel with a 580 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $4,999, the Rocket R Nine One is designed for passionate enthusiasts and semi-commercial users who accept nothing but the best. The dual boiler design allows simultaneous brewing and steaming, making it ideal for milk-based drinks without any wait time.
In terms of build quality, the Rocket R Nine One is a substantial machine, weighing in at 30.0 kg, manufactured in Italy, drawing 2200W of power. With dimensions of 340 x 530 x 480 mm (W×D×H), make sure you have adequate counter space. It offers both reservoir and direct plumbing options for maximum flexibility.
