Introduction

The Oscar positions itself as one of the most affordable heat exchanger machines on the market. This pricing strategy makes it an attractive option for home enthusiasts looking to upgrade from single boiler machines without venturing into the higher price brackets of machines like the Rocket Appartamento or Lelit Mara X.

Brief history of Nuova Simonelli

Nuova Simonelli, an Italian espresso machine manufacturer, has been a prominent player in the coffee industry since 1936. With over eight decades of experience, the company has built a reputation for producing high-quality commercial espresso machines. Nuova Simonelli’s expertise is widely recognised; they have been the official supplier for the World Barista Championship for several years, showcasing their commitment to excellence in espresso preparation.

1999 saw the launch of ‘Oscar’, the semi-professional coffee machine with high-level technical features. It had a thermo-compensated group, a semi-professional portafilter and thermosyphon water heating system.

In 2016 as a significant upgrade to the original Oscar, Oscar II aims to bring professional-level features to home baristas and small businesses alike.

Overview of the Oscar II

The Nuova Simonelli Oscar represents the company’s foray into the prosumer market, bridging the gap between entry-level home machines and commercial-grade equipment. 

The Oscar’s target audience includes:

• Home baristas seeking to elevate their espresso game
• Small cafes or restaurants requiring a reliable, commercial-grade machine
• Offices desiring quality coffee without the complexity of more advanced machines

With its combination of professional features, compact design, and competitive pricing, the Oscar aims to offer a taste of commercial-grade espresso making to a broader audience. It promises to deliver cafe-quality drinks without the steep learning curve or price tag associated with more advanced prosumer machines.

Specifications and Technical Details

Dimensions and weight

The Nuova Simonelli Oscar boasts a compact footprint, making it suitable for home kitchens and small commercial spaces alike:

• Width: 300 mm (11.8 inches)
• Height: 400 mm (15.8 inches)
• Depth: 408 mm (16 inches)
• Net Weight: 13 kg (28.66 lbs)

This relatively small size allows the Oscar to fit comfortably under most kitchen cabinets, though it’s worth noting that you’ll need additional clearance for accessing the water reservoir and cup warmer.

Boiler specifications

At the heart of the Oscar is its heat exchanger system, featuring:

• A 2-litre copper boiler
• Operating pressure of 0.166 MPa (1.66 bar)
• Maximum inlet pressure of 0.65 MPa (6.5 bar)

The copper boiler ensures excellent heat retention and distribution, while the heat exchanger design allows for simultaneous brewing and steaming - a significant upgrade from single boiler machines.

Pump type

The Oscar utilises a vibratory pump, which is standard for machines in this price range. While slightly louder than rotary pumps found in higher-end machines, it’s perfectly capable of producing the required 9 bars of pressure for espresso extraction.

Electrical requirements

• Voltage: 220-240V, 50 Hz (for most European and UK markets)
• Power consumption: 1200W

This power rating allows for quick heat-up times and stable temperatures during operation, making the Oscar energy-efficient compared to larger commercial machines.

Design and Build Quality

Materials used

The Nuova Simonelli Oscar showcases a blend of durability and aesthetics in its construction:

• Body: Primarily stainless steel, with some plastic components
• Boiler: Copper, ensuring excellent heat retention and distribution
• Portafilter: Commercial-grade 58mm, made of chrome-plated brass
• Drip tray: Stainless steel grate with a plastic base

While the use of some plastic elements (particularly in the top panel and drip tray) may be seen as a compromise, it helps keep the machine’s weight and cost down without significantly impacting performance or longevity.

Aesthetic considerations

The Oscar’s design is a departure from the traditional look of many espresso machines:

• Sleek, modern appearance with a hint of retro-futuristic styling
