Overview
The Rocket Cinquantotto — Italian for "fifty-eight," referencing the 58mm portafilter standard — is a dual boiler E61 machine that represents Rocket core dual boiler offering at a more accessible price than the R Nine One. Featuring a 580ml copper brew boiler and 1.8L steam boiler with PID control on both, the Cinquantotto delivers the temperature stability and simultaneous brew/steam capability that dual boiler enthusiasts demand. The E61 group head provides excellent thermal stability and the pre-infusion characteristics loved by traditional espresso aficionados. The rotary pump ensures quiet operation and enables direct plumbing. Build quality reflects Rocket Italian manufacturing heritage with polished stainless steel, quality chrome accents, and well-organized internal components. Dual pressure gauges provide at-a-glance monitoring, and a cup warmer keeps cups ready. The Cinquantotto lacks the pressure profiling capability of the R Nine One but delivers otherwise comparable dual boiler performance at a significantly lower price. It is an excellent choice for the home barista who wants dual boiler stability, rotary pump smoothness, and E61 heritage in a beautifully crafted package.
The Rocket Cinquantotto comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a dual boiler boiler system made of copper with a 580 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $2,999, the Rocket Cinquantotto is designed for dedicated prosumers who demand professional-grade equipment. 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 Cinquantotto is a substantial machine, weighing in at 27.0 kg, manufactured in Italy, drawing 1600W of power. With dimensions of 330 x 450 x 420 mm (W×D×H), make sure you have adequate counter space. It offers both reservoir and direct plumbing options for maximum flexibility.
