Footprint and space requirements

Despite its robust dual-boiler system, the S1 Mini Vivaldi II maintains a relatively compact footprint. Its dimensions make it suitable for most home kitchen countertops. It’s worth noting that you’ll need to account for additional space above the machine to access the cup warming tray and water reservoir.

The machine’s depth allows it to fit comfortably under most standard kitchen cabinets, though it’s advisable to leave some clearance for heat dissipation and easy access to the water tank. The drip tray is generously sized, reducing the frequency of emptying, but it does extend the machine’s footprint slightly when in use.

One thoughtful design feature is the front-accessible water reservoir. Unlike many machines that require access from the top to refill, the S1 Mini Vivaldi II’s tank can be easily removed and refilled from the front, making it more convenient for users who may have limited overhead space.

Core Functionality

Espresso extraction process

The La Spaziale S1 Mini Vivaldi II excels in its primary function: espresso extraction. The machine utilizes a 53mm portafilter, which is slightly smaller than the industry-standard 58mm. While this may limit aftermarket accessory options, it doesn’t compromise the quality of espresso produced.

The group head is directly connected to the brew boiler, ensuring excellent temperature stability throughout the extraction process. The machine operates at a standard 9 bar of pressure, which can be adjusted if desired. The vibratory pump provides consistent pressure, resulting in even extractions.

One of the standout features is the volumetric dosing system. This allows users to program precise shot volumes, ensuring consistency across multiple extractions. For those who prefer manual control, the machine also offers the ability to start and stop shots manually.

Temperature stability data

Temperature stability is crucial for consistent espresso extraction, and the S1 Mini Vivaldi II performs admirably in this regard. The PID-controlled brew boiler maintains temperature within a tight range of ±0.5°C. Users can adjust the brew temperature in 1°C increments from 91°C to 97°C, allowing for fine-tuning based on different coffee beans and roast levels.

The machine also features a unique “Offset Differential” function, which allows users to calibrate the displayed temperature to match the actual brew temperature at the group head. This level of precision is typically found only in more expensive machines.

Pressure profiling capabilities

While the S1 Mini Vivaldi II doesn’t offer built-in pressure profiling, it does provide a consistent 9 bar of pressure throughout the extraction. For those interested in experimenting with pressure, an optional pre-infusion chamber can be installed, allowing for a gentler start to the extraction process.

Steam wand performance metrics

The steam wand on the S1 Mini Vivaldi II is a standout feature. Powered by the 1.2 litre steam boiler with a 1250 Watt heating element, it delivers dry, powerful steam that can texture milk quickly and efficiently. The four-hole steam tip provides excellent control and allows for creating microfoam suitable for latte art.

The steam wand is fully articulated, making it easy to find the right angle for your pitcher. The steam power is controlled by a lever, which offers more precise control compared to knob-operated systems found on some competitors.

In testing, the machine can steam enough milk for a medium-sized latte in about 20-25 seconds, which is impressive for a machine in this class. The quick recovery time of the steam boiler means that it’s ready for the next drink almost immediately, making it suitable for preparing multiple milk-based drinks in succession.

• The front-accessible water reservoir makes refilling convenient.
• The large drip tray reduces the frequency of emptying.
• Volumetric dosing allows for hands-free operation once the shot is started.
• The powerful steam wand enables quick milk texturing.

One potential workflow interruption is the need to wait for the steam boiler to recover if preparing multiple milk-based drinks in quick succession. However, this recovery time is relatively short thanks to the powerful heating element.

Ease of adjustments and customisation

The S1 Mini Vivaldi II offers several points of customisation:

• Brew temperature can be adjusted in 1°C increments via the front panel.
• The unique Offset Differential feature allows for precise calibration of the displayed temperature to the actual brew temperature.
• Shot volumes for both single and double shots can be easily programmed.
• Brew pressure can be adjusted, although this requires removing the drip tray and splash guard.

While these adjustments are relatively straightforward, some users might find the lack of a digital display limiting when it comes to fine-tuning settings. The machine relies on LED indicators for temperature, which can be less intuitive than a numerical display.

The 53mm portafilter size may limit aftermarket customisation options compared to the more standard 58mm size. However, La Spaziale does offer some accessories, including a bottomless portafilter and different basket sizes.

Maintenance and Longevity

Regular cleaning requirements

The La Spaziale S1 Mini Vivaldi II, like all espresso machines, requires regular maintenance to ensure optimal performance and longevity. The cleaning routine is relatively straightforward:
