Rocket R58 Tune

Rocket R58 Tune – Dual boiler espresso machine with TUNE Pressure Profiling

Three bar builds up slowly. The puck saturates evenly, blooms, begins to breathe. On the display, the seconds you chose yourself tick by. The rotary pump works quietly – the grinder next to it sounds more present. Then the pressure climbs to nine bar, the first drops fall copper-coloured into the cup. Just before the end, the pressure drops back to three bar. The shot finishes gently, without that last bitter sip that can otherwise show up at the end of an espresso.

That's TUNE technology. And it's only part of what makes the Rocket R58 Tune what it is.

Coffee Coaching Club is a partner of Rocket in Switzerland. Your purchase includes our private barista course (in German or English, in Bern or Zurich), where we introduce you to extraction and the espresso ritual. The course is for up to two people from the same household or company attending together, and must take place within one month of the machine's delivery – after that, the entitlement lapses. Get in touch with us for the course and we'll find a date together.

TUNE technology – three phases, one shot

TUNE technology times two phases of the extraction: the pre-infusion at the start and the final phase just before the shot ends. Both run at a fixed pressure of three bar. In between, the classic pressure curve you know from espresso stays untouched.

The slow pre-infusion saturates the puck evenly and reduces channeling – small cracks in the coffee bed that let water shoot through too fast and extract unevenly. The lowered final phase softens the bitter compounds that, as experience shows, tend to release from the puck towards the end.

This isn't a promise of the perfect shot. It's a way to shape the aromatic window deliberately – newly with every coffee, differently with every roast. Our opinion is one among many: pressure profiling is a learning process, not a button press to perfection. What the machine can do, if that appeals to you: you shape the two three-bar phases, pull them differently for different beans, and watch what the coffee does.

Communication Pod and Push-Turn knob

Magnetically mounted next to the brew group sits the Communication Pod – a colour touchscreen display. Here you read off boiler temperatures, adjust them, switch between TUNE settings, and watch the built-in shot timer in real time.

Next to it, the new Push-Turn knob. Press to purge, turn to control. One movement, two functions – the morning workflow gets calmer without losing any ease of use.

Dual boiler, PID and E61 brew group

Two independently PID-controlled boilers – one for coffee (0.58 litres), one for steam (1.8 litres). Brewing espresso and steaming milk run in parallel instead of one after the other. The temperature stays constant, the workflow flows. If cappuccino or latte is a regular thing for you, this difference is noticeable from day one.

The E61 brew group is the mechanical heart of the machine. It stands for thermal stability, classic construction, and a design legacy that has shaped the espresso world for decades. Our opinion is one among many: in our view, saturated brew groups deliver an even more refined aromatic picture. But the E61 has a class of its own – the calm pre-infusion through the lever, the mechanical presence, the maintenance-friendly build. If you want an E61, you want it for good reasons.

Rotary pump and workflow

The rotary pump runs noticeably quieter than a vibration pump. Constant pressure, smooth running, long lifespan. The R58 Tune can run from its internal 1.9-litre water tank or connect directly to a fixed water line. Both are supported out of the box. That makes it fit on the kitchen counter just as well as in a permanently plumbed setup.

Cool-touch wands for steam and hot water make the workflow safer. Thanks to the reworked system, heat-up time is around ten to fifteen minutes, depending on ambient temperature. As with any dual boiler, a short warm-up phase with a few practice pulls helps until the aromatic profile settles in.

Chrome or matte black – design as a feeling

The R58 Tune comes in two finishes. Chrome – the polished stainless steel casing that has shaped the Rocket line for decades: reflection, warmth, classic Italian workshop aesthetics. Matte black – the monolithic version, calm, modern, with an understated character that blends into any dark counter.

Nobody buys an R58 Tune because it makes measurably better espresso than other machines in this class. It gets bought because it stands on the counter and conveys something – the sound of the pump in the morning, the feel of the new knob, the quiet of the display before the first shot. A feeling that begins with the first glance and doesn't stop at the first sip. If you want it, you know why.

At a glance

Who the Rocket R58 Tune is for

For everyone who wants a dual boiler with honest Italian craftsmanship. For everyone who wants to prepare espresso and milk foam in parallel instead of one after the other. For everyone who wants to explore different roasts and origins sensorially with TUNE technology, without diving into complex profiling software. For everyone who appreciates the quiet sound of a rotary pump.

The R58 Tune fits tank operation on the kitchen counter just as well as a setup connected to a fixed water line. It's a machine that, across Switzerland, stands wherever espresso gets brewed every day – not a display piece, but a tool.

Matching grinders, scales and tampers

A machine like the R58 Tune only unfolds its character with the right peripherals. For grinders, we recommend from two worlds. For everyone who wants an affordable and precise grinder: the VS3 from our Varia coffee grinders. If you want more – bigger burrs, different RPM behaviour, a different aromatic profile – you'll find a different chapter in the VS6 from the same collection or in the EG-1 from Weber Workshops.

For weighing and dosing: Normcore scales deliver compact, precise models without app gimmicks. The Acaia scales bring a flow-rate display, app connectivity and Bluetooth integration, if that appeals to you.

For tamping, the spring-loaded Normcore tamper from our Tamper Collection is a reliable companion. If you're after a different level of feel and finesse, take a look at the Weber Workshops tampers from the same collection.

If you're still unsure where the R58 Tune stands among other dual boilers, our coffee machine advisor tool can help – there you can see which setups make sense in which combination.

Shipping, showroom and financing

Delivery in two to four business days to Switzerland and Liechtenstein. Financing available. For higher-priced machines like the R58 Tune, we recommend pickup at our showroom in Bern or at the Zurich Oerlikon showroom – that way the machine is handed over directly and any questions can be clarified on the spot.

You can see the R58 Tune in person in our showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b). Since both colour options aren't necessarily on site at the same time, a quick call during business hours or a message to [email protected] helps if you want to see it in a specific finish.

Frequently asked questions about the Rocket R58 Tune

What distinguishes the R58 Tune from the R Cinquantotto?

The R58 Tune is the younger generation of the Rocket dual boiler platform, reworked in collaboration with the Milan-based V12 Design Studio. New are the TUNE technology for time-controlling pre-infusion and the final phase at three bar, the magnetically mounted Communication Pod with touchscreen, the new Push-Turn knob for combined operation, and a faster heat-up system. The core architecture stays: dual boiler, E61 brew group, rotary pump, PID.

How long does the R58 Tune take to heat up?

The R58 Tune is ready to brew and steam after about ten to fifteen minutes, depending on ambient temperature. As with any dual boiler, a short warm-up phase with a few practice pulls helps until the brew group and aromatic profile settle in.

Can the R58 Tune be connected to a fixed water line?

Yes. The R58 Tune works both from the internal 1.9-litre water tank and directly connected to a fixed water line. The rotary pump is designed for both operating modes – it runs quietly and delivers constant pressure.

Which grinder is recommended for the Rocket R58 Tune?

If you're looking for an affordable and precise grinder for the R58 Tune, the Varia VS3 sets you up well. If more body, different burrs and a distinct RPM behaviour is what you want, look at the Varia VS6 or the Weber Workshops EG-1. Our opinion is one among many – each of these grinders has its own character and its own fans.

What's the difference between Chrome and matte black?

Technically identical. Both finishes have the same architecture, the same TUNE technology, the same brew group. The difference is design: Chrome is the polished stainless steel that has shaped the Rocket line for decades – reflection, warmth, classic Italian. Matte black is the monolithic, understated version that blends more quietly into dark kitchens.

Can I see the Rocket R58 Tune in the showroom?

Yes. You can see the R58 Tune in person in our showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b). Since not every machine is on site in both showrooms at all times, a quick call during business hours helps if you want to see it in a specific colour.
