Three Groups, Three Temperatures, One Machine
The Rocket Espresso R9 3 Group is a fully saturated multi-boiler commercial espresso machine built for high-volume specialty cafés and multi-roaster operations that need maximum throughput and per-group temperature independence at the same time. Where most 3-group machines share a single brew boiler across all groups, the R9 gives each group its own dedicated 1.9L brew boiler and PID controller, making it possible to run three different roasts, three different profiles, and three independent baristas on one machine simultaneously. Designed by Ennio Berti in Milan and built to Rocket's exacting standards, the R9 3 Group is the right call for venues that have outgrown a 2-group and won't settle for less precision.
Rocket Espresso R9 3 Group Features
3x Independent 1.9L Brew Boilers - One Per Group
Each of the three group heads runs from its own dedicated 1.9L brew boiler, fully temperature-independent from the others. Run a light roast single-origin, a dark espresso blend, and a decaf simultaneously, each dialled in at its own exact temperature with no crossover between groups.
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. Three baristas can work all three groups at the same time with no shared controls in the way.
Oversized 12L Steam Boiler
A high-capacity 12L steam boiler, sized specifically for 3-group throughput, with pressure transducer control for rapid, sustained steam recovery under heavy milk-drink demand across a full service rush.
Fully Saturated Group Heads
Continuous water circulation from the boiler to the group maintains a consistent thermal baseline shot after shot, reducing temperature drift and keeping results repeatable across your entire 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 across three active stations.
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.
Polished AISI 304 Stainless Steel Construction
Full polished stainless steel chassis, Italian-made in Milan.
R9 3 Group – What Makes It Special
The R9 3 Group is the highest-output machine in Rocket's commercial lineup and the only 3-group where every group gets its own 1.9L brew boiler. In practice, that means a café can run a light roast single-origin, a dark espresso blend, and a decaf at the same time, each at its own exact temperature, on one machine, with three baristas operating fully independently. That level of per-group flexibility doesn't exist on most 3-group machines at any price. The 12L steam boiler is sized to match, holding up across the busiest service rushes without recovery delays. And with a lower profile designed to open up the bar-to-customer sightline, the R9 3 Group is built to work as hard as the team running it.
Who the R9 3 Group Is For
-
High-volume speciality cafés and flagship espresso bars serving 500–700+ drinks per day.
-
Multi-roaster concepts running three different roasts or profiles simultaneously on one machine.
-
Operations with three baristas working fully independently at peak service.
-
Venues that have outgrown a 2-group and need maximum throughput without adding a second machine.
-
Coffee programs where per-group precision and bar-forward design are both non-negotiable.
How It Compares to Other Espresso Machines
R9 3 Group vs. La Marzocco Linea PB 3 Group
Both are premium Italian multi-boiler 3-group machines targeting high-volume specialty service. The R9 wins on per-group independent boiler control: each group runs its own dedicated 1.9L brew boiler, and it delivers that capability at a more competitive price point than the Linea PB.
R9 3 Group vs. Rocket Espresso R9 2 Group
Same machine, scaled for higher volume. The 3 Group adds a third independent 1.9L brew boiler for a third fully independent group, and steps up to a 12L steam boiler (vs. 9L on the 2 Group) to match the additional throughput demand. The right choice for venues that have maxed out what a 2-group can do.
R9 3 Group vs. Nuova Simonelli Aurelia Wave 3 Group
Both operate in the high-volume commercial 3-group tier. The R9 wins on per-group PID precision and multi-roaster profile flexibility: each group's independent boiler and 0.1°C PID adjustment gives it an edge for specialty programs running varied roasts and profiles simultaneously.
Key Takeaway
The Rocket Espresso R9 3 Group is built for venues that need everything: maximum throughput, per-group temperature independence, and the steam capacity to match, all on one machine. If your program has outgrown shared-boiler limitations and your team needs three fully independent stations running at the same time, this is the machine that makes it possible.
Why Espresso Parts Recommends the R9
At Espresso Parts, we support cafés and technicians every day. We see which machines hold up under sustained high-volume service, give baristas real control, and stay reliable year after year. The R9 3 Group earns our recommendation because it delivers something genuinely rare: true per-group boiler independence across three groups, with the steam capacity and build quality to back it up.
We recommend the R9 3 Group because it:
-
Handles 500–700+ drinks per day with shot-to-shot consistency through fully saturated group heads.
-
Supports three-barista workflows with fully independent control clusters, shot timers, and PIDs per group.
-
Recovers fast under sustained high-volume milk-drink demand through an oversized 12L 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 all three groups run at different brew temperatures?
A: Yes. Each group has its own 1.9L brew boiler and PID controller, adjustable in 0.1°C increments. All three can run at completely different temperatures simultaneously with no crossover between groups.
Q: Can the steam boiler keep up with three baristas steaming simultaneously?
A: Yes. The 12L steam boiler on the 3 Group — larger than the 9L on the 2 Group — uses pressure transducer control and is sized specifically for 3-group throughput. It holds up across a full-service rush without recovery delays.
Q: Can three baristas operate all groups independently at the same time?
A: Yes. Each group has its own control cluster, shot timer, and PID. Three baristas can each run their own group simultaneously with no shared controls and no temperature bleed between groups.
Q: What grinders pair well with the R9 3 Group?
A: At this volume and precision level, we recommend one commercial grinder per group. The Mahlkönig E65S GbW is a strong fit for most specialty programs; running one per group gives you the same per-group independence at the grinder that the R9 delivers at the machine. For higher-output stations, the Mahlkönig E80S GbW is worth considering.
Q: How does the R9 3 Group differ from the R9 2 Group?
A: The 3 Group adds a third fully independent 1.9L brew boiler and group head, and steps up to a 12L steam boiler to match the additional throughput. Everything else, per-group PID precision, saturated group design, build quality, and bar-forward ergonomics, is the same machine scaled up.
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 3 Group represents the full reach of their commercial ambition: per-group boiler independence across three stations, saturated-group precision, and a purposeful bar-forward design by Ennio Berti, built for the high-volume speciality programs that demand it.
