Rocket R58 Complete Review

Rocket R58Rocket R58

Rocket Espresso R58 Milano is finally building a dual boiler in the tried and tested E61 design – and one immediately asks oneself:

Is that really nessecary?

Our test proves: Yes, it is!

That the status quo was turned upside down with the prosaically R58 stainless steel beauty would nevertheless have gone too far. The flagship from Settala becomes the Primus inter Pares thanks to a number of exciting detailed solutions that did not exist before. Apart from an almost error-free performance …

First impressions

Well, what a balancing act this was to get up on my counter! Stubborn 29 kg have to be lifted out of the cardboard box, which has been designed and secured as usual, before the chrome sun rises in the kitchen at home. 

But then she stands there and does not want to give way anymore: a steel, timelessly elegant piece of espresso technology, washed with pretty much all equipment water and robustly processed, typical of Rocket. Initially in conversation as “Rivoluzione”, the R58 neither denies externally nor in terms of weight the close relationship to Rockets, a professional series that has only been available since mid-2011.

To celebrate the day, the small but fine manufacturer from the Milanese district has added, not only an actually usable (!) Tamper made of aluminum, but also the stable stainless steel rail as standard, in addition to two portafilter, exemplary operating instructions and an introduction by DVD tutorial. Bravo! 

The R58 looks almost a bit like an insect thanks to the laterally extending, generously dimensioned and completely free-moving no-burn lances, which are reminiscent of feelers. Since the milk froth should come to a relaxed show. Two easy-to-read, high-quality pressure gauges are installed on the left and right above the drip tray. The best thing, however: the one installed in almost all PID competitors,

Instead of this, the R58-Barista controls all relevant parameters (boiler temperatures, operating status of the steam boiler, operating mode tank / permanent water) via a small metal box with a display panel, which can be docked to the side of the machine via a serial port if required. An obvious as well as sensational idea, which in terms of execution can still be improved, does not appear to be fully conceived. 

The unit itself makes a valuable impression. Rather, the machinist seems to have a problem with the connection between the cable and the rocket or control unit, which is certainly heavily used in everyday life. There is also no kind of holder or stand to be able to park them comfortably during operation, without losing sight of the brewing temperature. 

Ever thought about Bluetooth, gentlemen? At least a modern USB port should have been there in 2012. And, while we’re at mosern: why only one of the two rotary knobs was approved with an “R” will probably remain the secret of the product designers forever.

From the outside in

On the other hand, pure consequence rules. Despite the acute lack of space, the developers of the R58 have given it pretty much everything that is good and expensive:

The rotary pump, which can be adjusted from the outside with a brass screw, is quiet and relentlessly pulls the water out of the pipe or (depending on your taste) 2.6 liters, of course, a somewhat scarce) water tank, the fill levels are monitored electronically and both copper kettles are equipped with professional Armaflex insulation, which should be good for both the climate balance and the household budget. The operating pressures of the two with 0.58 (coffee) and 1,

Then only the actual conditions in the boiler are shown on the display of the control unit – no “calculated” brewing temperature at the group, which is always dependent on external factors such as the ambient temperature. 

Two 1,400 watt heating elements ensure stable conditions, an ingenious circuit prevents both of them from firing off simultaneously and limits the simultaneous power consumption to 1,550 watts. Others should make compromises; 

Rocket is definitely going full speed in technical terms.

Put it through its paces!

The pump purrs silky until after a short while both boilers are filled with water, after just seven and a half minutes the factory-set 105 ° C brewing boiler temperature has been reached. Another five minutes later, the macchina, including the empty cover, is ready for use and after almost exactly a quarter of an hour from the cold start, we open the steam valve for a few seconds to prevent the formation of a vacuum (and thus the potential carryover of milk into the kettle). Against this background, the machinist can hardly resist a happy grin: For a machine with an E61 brew group that weighs more than four kilos, this is a record-breaking fix.

The first two or three shots are for the bucket, as always, then everything fits as far. It takes a while for a racing car like the R58 to get the gods shot – but rarely before (especially not with a household machine) was it so much fun to get there. Dialing in temperature and pressure is child’s play; the clearly readable display is absolutely intuitive to use. After we have circled the optimum a couple of times, we ignite the “Gran Miscela” from La Tazza d’oro, which is still somewhat flat at approx. 92 ° C, two extra degrees below the rear, so that finally 107 ° C boiler temperature glows on the display; according to the table provided by Rocket, thankfully, this corresponds exactly to 94, 6 ° C brewing temperature – and “boom”! Then the hut burns. Chilled to ice cold, the espresso clipper would say. Finally, just for fun, we donate an extra gram of caffè, just for the sake of fatness. We are in caffeine heaven, indulge in chocolate nuances and can literally smell the Sardinian sea.

The system is also unable to overturn multiple purchases in direct succession; The powerful heater quickly and quickly ironed out the short sumps that were created despite the lack of preheating, such as that used by Vibiemme in the Domobar Super. The long lance makes every angle possible, and the 1.7 liter kettle provides – especially if you jazz it up a bit – more than enough bone-dry wumms to do a good ballet with the factory-installed 2-hole nozzle . With a massive 4-hole nozzle of the R series (unfortunately not included), it should almost be towards an unintended explosion for most home users. Due to the precisely responsive professional spring valves, sensitive metering of the steam and fine-pored latte art foam are no problem as a result. Conclusion: pulling all the barista registers with this macchina is as easy as it is entertaining.

Summery

Their complete equipment as well as the temperature control, which is as easy to use as it is surprisingly stable even without an additional heat exchanger, not only make the new Rocket double boiler Macchina an absolute must-have item for every ambitious home coffeeologist, but also predestines it as a welcome test and thus Tool for small roasters, for example. With such qualities in the luggage, the R58 should blow through the highly competitive dual boiler market properly. In the end, the real highlight is that the concentrated technology qua smart handheld solution respects the classic design. If Rocket still has an insight and in the medium term a few additional Eurons for a permanently higher-quality USB interface (or a Bluetooth solution along with an iPhone app!), but the competition can dress up warmly.

My thoughts

  • Very extensive equipment
  • First-class espresso quality through flexible brewing temperature
  • PID control via external control panel, absolutely flexible hot water and steam lances
  • Impeccable workmanship
  • Temperature stable (deviation <1 ° C)
  • Very quiet
  • Great value for money

Specs:

  • Dimensions: (width / height / depth in cm) 31 x 41 x 44
  • Weight: 29 kg Power: 1,400 W / 1,400 W (together max. 1,550 W)
  • Kettle: 1.7 liters (steam / hot water), 0.58 liters (coffee)

Features:

  • Dual boiler system, electronically adjustable brewing temperature (PID)
  • Electronically adjustable boiler pressure for steam boilers, boiler insulation
  • Cool touch technology, brewing pressure can be easily adjusted from the outside
  • Tank / fixed water operation switchable, steam boiler can be deactivated if necessary
  • Rotary pump
  • If necessary, attachable external control panel

There is not doubt in my mind, that this amazing espresso machine, is one of those “Once in a life time” purchases, that you know are expensive, but you also feel in your bones that you get an amazing product that you never regret investing in.
