Despite its compact size, the CUBE R doesn’t feel cramped in use. The drip tray is generously sized, providing ample workspace for espresso preparation. The cup warming tray on top of the machine is also well-proportioned, allowing for storage and preheating of several cups at once.

It’s worth noting that while the machine is compact, its weight means it’s not easily moved once in place. This weight, however, contributes to the machine’s stability during operation, which is crucial for consistent espresso extraction.

The CUBE R’s thoughtful design extends to its internals as well. The layout of components allows for easy access for cleaning and maintenance, a consideration that’s often overlooked in home espresso machines.

Core Functionality

Espresso extraction process

The Sanremo CUBE R utilizes a traditional E61 group head with mechanical pre-infusion, a feature typically found in high-end commercial machines. This group head design allows for consistent water distribution across the coffee puck, promoting even extraction.

The extraction process begins when the user lifts the lever on the E61 group head. This action activates the mechanical pre-infusion, which gently saturates the coffee grounds before full pressure is applied. This pre-infusion stage can help reduce channeling and improve overall extraction quality.

The CUBE R’s rotary pump, rated at 54 L/h, provides consistent pressure throughout the extraction process. This stability is crucial for achieving balanced, well-extracted espresso shots. The pump’s quiet operation is an added bonus, especially for home environments.

Temperature stability data

Temperature stability is a critical factor in espresso extraction, and the CUBE R performs admirably in this regard. The machine employs a PID (Proportional-Integral-Derivative) temperature control system, which allows for precise and stable temperature management.

The boiler temperature can be adjusted between 115°C and 130°C, corresponding to an estimated brew temperature range of 89.5°C to 96.3°C. This level of control allows users to fine-tune their extractions based on the specific coffee beans they’re using.

The CUBE R maintains consistent temperatures well, even during back-to-back shots. However, as with most heat exchanger machines, a brief cooling flush may be necessary before pulling a shot to ensure optimal brew temperature.

Pressure profiling capabilities

The CUBE R doesn’t offer built-in pressure profiling capabilities like some more advanced (and typically more expensive) machines. However, the E61 group head does allow for some manual pressure manipulation by skilled users.

By partially closing the lever during extraction, users can reduce the pressure, potentially allowing for some basic form of pressure profiling. While not as precise or repeatable as electronic pressure profiling systems, this manual method can still offer some room for experimentation.

Steam wand performance metrics

The CUBE R features a professional-grade steam wand with a cool-touch design for safety. The steam power is derived from the same 1.9L boiler used for brewing, which means the machine can steam milk and brew espresso simultaneously - a significant advantage over single-boiler machines.

The steam power is more than adequate for home use. The wand allows for fine control over milk texturing, making it possible to create microfoam suitable for latte art.

The steam wand’s operation is controlled by a unique bi-directional lever. A slight twist to the right provides a quick purge, while a quarter turn to the left locks the wand on for continuous steaming. This design combines the precision of a knob with the ease of use of a lever.

In practice, you will be able to steam enough milk for a latte in about 30-40 seconds, which is respectable performance for a machine in this class. The quality of the steam is consistent, allowing for the creation of silky microfoam when proper technique is used.

User Experience

Learning curve

The Sanremo CUBE R strikes a balance between professional-grade features and user-friendly operation, making it suitable for both experienced home baristas and enthusiastic beginners.

For those new to semi-automatic espresso machines, there will be a learning curve. Understanding the nuances of grind size, dose, tamping pressure, and extraction time is essential for getting the best results from the CUBE R. However, the machine’s consistent performance and clear feedback (via the pressure gauges and shot timer) make this learning process more manageable.

Experienced users will appreciate the familiar E61 group head and the ability to fine-tune parameters like boiler temperature. The transition from other semi-automatic machines to the CUBE R is generally smooth, with most users reporting a quick adaptation period.

Daily operation workflow

The daily workflow with the CUBE R is straightforward and efficient:

• Turn on the machine (or use the app to schedule automatic start-up).
• Allow about 15-20 minutes for the machine to heat up fully.
• Perform a quick flush of the group head to stabilize temperature.
• Grind, dose, and tamp your coffee.
• Lock in the portafilter and start extraction by lifting the E61 lever.
• Use the digital display to monitor shot time.
• Steam milk if preparing a milk-based drink.
• Clean the group head and steam wand after use.

The rotary pump allows for quiet operation, making early morning coffee routines less disruptive. The ability to plumb the machine directly to a water line (an option not available on machines like the Rancilio Silvia) can further streamline the workflow by eliminating the need to refill the water tank.

Ease of adjustments and customisation

The CUBE R offers several ways to customize and adjust your espresso:

• Temperature Adjustment: The boiler temperature can be easily adjusted via the digital display or the smartphone app. This allows users to experiment with different temperatures for various coffee roasts.
• Pre-Infusion: While not electronically controllable, the E61 group head’s mechanical pre-infusion can be manipulated to some extent by skilled users.
• App Control: The WiFi-enabled app adds a layer of customization not found on many machines in this class. Users can schedule on/off times, adjust boiler temperature remotely, and even track their coffee consumption.
• Steam Power: The unique bi-directional steam lever allows for fine control over steam output, making it easier to achieve the desired milk texture.
• Aesthetics: With eight color options available, users can choose a machine that best fits their kitchen decor or personal style.

While the CUBE R doesn’t offer the same level of customization as more advanced (and typically more expensive) machines like the Decent DE1PRO, it provides enough adjustability to satisfy most home baristas.

The machine’s interface, combining traditional controls with modern digital elements, is generally intuitive. The pressure gauges provide clear visual feedback, while the digital display offers precise temperature control and shot timing.

• The 54mm group head and 1.9L boiler provide ample stability for consistent double shot extraction.
• The rotary pump ensures steady pressure throughout the longer extraction time of a double shot.

In both scenarios, the digital shot timer proves useful for maintaining consistency. However, as with most prosumer machines, users may find that dialing in for double shots is generally easier and produces more consistent results.

Light vs. dark roasts

The CUBE R’s performance across different roast levels is commendable, thanks to its temperature adjustment capabilities:

For light roasts:

• Users can increase the boiler temperature to extract the delicate flavors of light roasts effectively.
• The E61 group head’s pre-infusion can be particularly beneficial for light roasts, helping to ensure even extraction.
• Some users report that a slightly longer pre-infusion time can help bring out the best in light roasts.

For dark roasts:

• The ability to lower the boiler temperature helps prevent over-extraction and bitterness in darker roasts.
• The consistent pressure from the rotary pump aids in controlling extraction with oilier dark roast beans.

The CUBE R’s temperature stability allows for “temperature surfing” - a technique where users can fine-tune the brew temperature by timing their shot pull after a cooling flush. This can be particularly useful when switching between different roast levels.

Performance with milk-based drinks

The CUBE R performs admirably when it comes to milk-based drinks:

• The steam wand, while not as powerful as some commercial machines, provides ample steam for home use.
• Users report being able to steam enough milk for a latte in about 30-40 seconds.
