The La Spaziale S1 Vivaldi II is a professional-grade, single-group dual-boiler espresso machine designed to bring barista-quality performance into the home. With its compact 15-inch height, stainless steel construction, programmable brewing controls, and commercial-inspired components, the Vivaldi II delivers powerful espresso performance without taking over your countertop.

Developed from the original Vivaldi platform with extensive customer feedback and design refinements, the Vivaldi II incorporates enhanced temperature control, programmable passive pre-infusion, a redesigned top cover, improved temperature sensing, a dual manometer, and a precision 0.9 mm four-hole steam tip.

Key Features

Compact Professional Design

Standing just 15 inches high, the Vivaldi II is designed to fit comfortably beneath standard kitchen cabinetry while maintaining a professional appearance.

Its redesigned stainless steel top cover eliminates the previous Plexi cup guard and provides a cleaner, more practical design.

Dual-Boiler System

The Vivaldi II uses dedicated boilers for brewing and steaming:

• 0.45-liter group boiler
• 2.5-liter steam boiler

The dual-boiler architecture allows the machine to maintain more independent control over brewing and steaming temperatures, supporting consistent espresso preparation and powerful milk steaming.

Programmable Passive Pre-Infusion

The Vivaldi II features programmable passive pre-infusion adjustable from 1 to 8 seconds.

Unlike traditional E61-style pre-infusion, this system allows the user to control both the duration of pre-infusion and the amount of water used during the initial saturation stage.

Once programmed, the selected pre-infusion setting is automatically applied whenever the brew cycle is started.

Programmable Offset Differential

The programmable offset differential allows the displayed LED temperature setting to correspond more closely with the temperature being delivered at the group.

The machine can be calibrated during testing so the temperature display accurately reflects the desired group temperature without requiring the user to purchase specialized testing equipment.

Precise Temperature Control

The Vivaldi II improves temperature accuracy through a more responsive heating system. The heater activates when the system detects a temperature drop of approximately 0.5°C, compared with the previous 1°C threshold.

This helps maintain more precise group-boiler temperatures while supporting improved steam-boiler performance.

Updated Temperature Sensing Probe

The updated temperature probe is submerged directly into the boilers, providing faster temperature response and improved reliability compared with the previous probe design.

One-Degree LED Temperature Display

The redesigned LED display provides temperature readings in 1-degree Celsius increments, from 91°C to 97°C.

This offers more precise temperature feedback than the previous 5-degree increment display.

0.9 mm Four-Hole Steam Tip

The Vivaldi II comes standard with a 0.9 mm four-hole steam tip. The smaller openings are designed to provide controlled steam delivery and make it easier to produce fine microfoam, including when working with smaller quantities of milk.

Dual Manometer

The dual manometer provides direct pressure monitoring without requiring a separate pressure-gauge portafilter.

It allows users to monitor both pump output pressure and steam boiler pressure for easier machine adjustment and operation.

Volumetric Dosing

The Vivaldi II features volumetric dosing that can be adjusted through the machine’s touchpad. This allows users to program and repeat preferred brew volumes with convenient button operation.

Direct-Plumbed Rotary Pump

The machine uses a rotary pump and is designed for direct-plumbed operation. A braided water line with a 3/8-inch John Guest fitting is included.

Bluetooth Connectivity

As of December 2021, Bluetooth connectivity is built into the Vivaldi’s software, providing modern connected functionality alongside its professional espresso controls.

Optional 7-Day Timer

A 7-day timer is available as an optional feature, allowing users to schedule machine operation according to their preferred routine.

Brewing & Temperature System

The Vivaldi II is designed around precise temperature management and repeatable brewing. Its dual-boiler configuration separates the group and steam systems, while programmable passive pre-infusion provides additional control over the initial stages of extraction.

The programmable offset differential and one-degree LED display further support precise temperature management, making it easier to establish repeatable brewing parameters.

Steam & Hot Water System

The Vivaldi II includes a swiveling stainless steel steam arm with a four-hole 0.9 mm steam tip for controlled milk steaming and microfoam production.

Additional features include:

• Manual steam valve
• Swivel stainless steel steam arm
• 0.9 mm four-hole steam tip
• Semi-automatic hot water delivery
• 2.5-liter steam boiler
• Electronic boiler refill

Safety & Diagnostic Features

The machine includes several systems designed to support reliable operation:

• Built-in safety thermostat
• Electronic boiler refill
• Fault diagnosis alarms
• Updated temperature sensing probe
• Dual manometer
• Direct-plumbed water system
