Per-Group Precision, Built for the Bar
The Rocket Espresso R9 is a fully saturated multi-boiler 2-group commercial espresso machine built for specialty cafés and high-volume espresso bars that need true per-group temperature independence. Where most 2-group machines share a single brew boiler across both groups, the R9 gives each group its own dedicated 1.9L brew boiler and PID controller, making it the right machine for multi-roaster programs, high-volume teams, and venues where dialling in each group independently isn't a luxury; it's a requirement. Designed by Ennio Berti in Milan and built to the exacting standards Rocket is known for, the R9 is a proper working machine that also looks the part.
Rocket Espresso R9 Features
Independent 1.9L Brew Boiler Per Group
Each group head runs from its own dedicated 1.9L brew boiler, fully temperature-independent. Set different brew temperatures on each group simultaneously for different roasts, origins, or drink profiles without any interference between them.
Per-Group PID Controller (0.1°C Increments)
Individual PID temperature control on each group with 0.1°C adjustment precision, plus a dedicated shot timer and automatic control cluster per group. Two baristas can work their respective groups at the same time with no shared controls in the way.
Large 9L Steam Boiler
A single high-capacity 9L steam boiler with a sensitive pressure transducer for rapid recovery under heavy milk-drink demand, built to hold up through peak service on high-volume menus.
Fully Saturated Group Heads
Continuous water circulation from boiler to group maintains a consistent thermal baseline shot after shot, reducing temperature drift and keeping results repeatable across your team.
Volumetric Shot Programming
Program exact shot volumes per group for consistent, repeatable dosing across all drinks, users, and shifts.
Cool-Touch No-Burn Steam Wands with Lever-Operated Valves
Ergonomic lever-operated steam valves and cool-touch wands for safe, efficient high-volume milk texturing, designed for continuous bar use.
Lowered Profile for Barista-Customer Interaction
Reduced machine height opens up the sightline between barista and customer — a deliberate design choice by Ennio Berti that improves both workflow and the bar experience.
86mm Cup Clearance
Standard 86mm cup height accommodates most commercial glassware and cup formats without tray adjustment.
Polished AISI 304 Stainless Steel Construction
Full-polished stainless steel chassis, Italian-made in Milan.
R9 – What Makes It Special
The R9 is the only machine in Rocket's commercial lineup where each group gets its own 1.9L brew boiler. In practice, that means you can pull a light roast single-origin on one group and a dark blend on the other at the same time — each dialled in at its own exact temperature, with zero interference between them. That kind of per-group flexibility is rare at this price point. Saturated group heads keep every shot consistent from start to finish, and the large 9L steam boiler holds up through demanding milk-drink menus without recovery delays. Designed with a lower profile to open up the bar-to-customer sightline, the R9 is built to work as hard as the team behind it.
Who the R9 Is For
- Specialty cafés and high-volume espresso bars serving 300–500+ drinks per day.
- Multi-roaster concepts that need exact, independent brew temperatures dialled in per group.
- Operations where multiple baristas each run their own group simultaneously.
- Venues where per-group flexibility and precision matter more than a centralised boiler setup.
- Coffee programs where the bar experience and machine aesthetic are both part of the brand.
How It Compares to Other Espresso Machines
RE Doppia vs. La Marzocco Linea PB 2 Group
Both are premium Italian multi-boiler machines targeting the same tier of specialty café. The R9 wins on per-group independent boiler control: each group runs its own dedicated brew boiler, and it delivers that capability at a more competitive price point than the Linea PB.
R9 vs. Rocket Espresso RE Doppia 2 Group
Same Italian commercial heritage, fundamentally different boiler architecture. The RE Doppia runs both groups from a single shared brew boiler, well-suited for high-volume cafés serving a consistent espresso program. The R9 gives each group its own 1.9L brew boiler, making it the right choice when per-group temperature independence is the priority: different roasts, different baristas, different profiles running at the same time.
Key Takeaway
The Rocket Espresso R9 is built for specialty programs that have outgrown shared-boiler limitations. If your menu, your roaster relationships, or your team's workflow demands that each group runs independently, on its own temperature, its own timer, its own PID, the R9 is the machine that makes that possible without compromise.
Why Espresso Parts Recommends the R9
At Espresso Parts, we support cafés and technicians every day. We see which machines give baristas real control, recover cleanly under pressure, and stay reliable through years of commercial service. The R9 earns our recommendation because it delivers something genuinely rare at this price: true per-group boiler independence in a machine that's built to last and designed to look good behind the bar.
We recommend the R9 because it:
- Gives each group its own dedicated 1.9L brew boiler and PID for true temperature independence, run two different roasts simultaneously with no compromise.
- Handles 300–500+ drinks per day with consistent thermostability through fully saturated group heads.
- Supports multi-barista workflows with independent control clusters, shot timers, and PIDs per group.
- Recovers fast under heavy milk-drink demand through a large 9L steam boiler with pressure transducer control.
- Delivers Italian craftsmanship and a purposeful bar-forward design, made in Milan by Rocket Espresso.
Frequently Asked Questions
Q: Can each group run at a different brew temperature?
A: Yes. Each group has its own 1.9L brew boiler and PID controller, adjustable in 0.1°C increments. Run two completely different roasts or drink profiles at the same time with no interference between groups.
Q: How is steam recovery during peak service?
A: The R9's large 9L steam boiler uses a sensitive pressure transducer to minimise recovery time even under heavy milk-drink demand, making it well-suited to high-volume café service.
Q: Can multiple baristas operate independently on the same machine?
A: Yes. Each group has its own control cluster, shot timer, and PID, so two baristas can work their respective groups simultaneously without any shared controls getting in the way.
Q: What grinders pair well with the R9?
A: For a machine at this level, we recommend commercial grinders that match its precision and throughput. The Mahlkönig E65S GbW is a strong fit for most specialty programs. For multi-roaster setups running different coffees per group, consider pairing one grinder per group — the Mahlkönig E65S GbW or E80S GbW on each side gives you the same per-group independence at the grinder that the R9 delivers at the machine.
Q: How does the R9 differ from the RE Doppia?
A: Both are 2-group Rocket machines, but with different boiler architectures. The RE Doppia uses a single shared brew boiler across both groups, reliable and efficient for consistent espresso programs. The R9 gives each group its own independent 1.9L brew boiler, making it the right choice when running different roasts, temperatures, or profiles simultaneously is a priority.
About the Brand: Rocket Espresso
Founded in Milan, Rocket Espresso was born from a belief that commercial-grade engineering had a place in the hands of serious baristas, whether behind a café bar or a home setup. Known for their uncompromising use of AISI stainless steel, precision Italian craftsmanship, and a design language that's distinctly Milan, Rocket builds machines that age well and perform harder. The R9 represents the top of their commercial ambition: per-group boiler independence, saturated-group precision, and a purposeful bar-forward design by Ennio Berti, built for the specialty cafés that demand it.
