In my humble opinion the Rocket Espresso Machines are some of the most visually appealing machines out there. And the Rocket R58 is no exception. Aside from the beautiful aesthetics, the Rocket R58 is built very well. The quality production of each machine is something that Rocket prides itself on. Each machine is hand crafted with commercial quality parts, from the rotary pump to the portafilter. Pulling delicious espresso with these machines is a wonderful experience. The Rocket R58 is truly a powerhouse espresso machine. It is a dual boiler machine, giving you the excellent control for both brewing and steaming. The dual boiler along with thermo siphon system design allows for stability in the espresso boiler and increased levels of steam pressure and hot water from the service boiler. The brewing boiler holds 0.58 liters while the hot water/steam boiler holds 1.7 liters. The Rocket R58 also features a remote PID, which keeps your countertop looking clean and the temperature in your control. The Rocket R58 is plumbable, so you can say goodbye to filling a water tank if that is something you wish to do. If you aren't good at goodbyes, not to worry, you can also use the 2.5 liter water reservoir. Watch the Crew Review below to get a good feel for this machine. Gail takes a close look at each part of the design before making herself a cappuccino. And a tasty looking one at that!
