Overview
The Rocket R58 is Rocket flagship dual boiler machine, named for its 58mm portafilter and R designation for rotary pump. Featuring independent copper brew boiler (580ml) and stainless steel steam boiler (1.8L), both PID-controlled, the R58 delivers uncompromising temperature stability and powerful steaming capability. The E61 group head provides excellent thermal mass, while the dual boiler architecture eliminates any compromise between brewing and steaming — both operate simultaneously at their optimal temperatures. The rotary pump delivers whisper-quiet operation and enables direct plumbing, though the reservoir provides ample capacity for stand-alone use. PID temperature is adjustable for both boilers through a digital display, and the machine features a built-in shot timer. The R58 is built in Rocket Milan factory with the same attention to detail as their commercial machines, featuring polished stainless steel panels, chrome accents, and premium internal components. Dual pressure gauges and a generous cup warmer complete the package. The R58 represents Rocket vision of the perfect home machine — dual boiler stability, rotary pump refinement, and E61 tradition combined in a beautifully crafted Italian chassis.
The Rocket R58 comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a dual boiler boiler system made of copper/stainless steel with a 580 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $3,399, the Rocket R58 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 R58 is a substantial machine, weighing in at 28.0 kg, manufactured in Italy, drawing 1800W of power. With dimensions of 340 x 460 x 420 mm (W×D×H), make sure you have adequate counter space. It offers both reservoir and direct plumbing options for maximum flexibility.
