E1 Prima

Introduction

Victoria Arduino has designed the E1 Prima to bridge the gap between professional equipment and home usability. It's aimed at serious coffee enthusiasts, small café owners, and roasters looking for a reliable machine for quality control.

Brief history of Victoria Arduino

Victoria Arduino has been at the forefront of espresso machine innovation since 1905, when Pier Teresio Arduino founded the company in Turin, Italy. Over the past century, Victoria Arduino has consistently pushed the boundaries of what’s possible, introducing game-changing technologies like horizontal boilers in 1939. This spirit of innovation and craftsmanship has made Victoria Arduino an iconic name in the coffee world.

Fast forward to today, and Victoria Arduino is still in charge of cutting-edge machines like the Eagle One Prima, affectionately known as the E1 Prima. Released in 2021, the E1 Prima is Victoria Arduino’s bold vision for the future of home espresso.

Overview of the E1 Prima

Positioned squarely in the premium prosumer market, the E1 Prima aims to bring the power and precision of Victoria Arduino’s commercial machines to passionate home baristas. It’s a machine for coffee nerds who refuse to compromise, even in the comfort of their kitchens.

Under the hood, it’s packing some serious heat, with innovative features like New Engine Optimization (NEO) technology for enhanced energy efficiency and temperature stability which enables simultaneous brewing and steaming, making the E1 Prima a multitasking marvel.

The E1 Prima isn’t for the faint of heart or light of wallet. But for those who can taste the difference between a 9-bar and 6-bar extraction, or who debate the merits of a 93°C vs 94°C brew temperature, this machine might just be the holy grail of home espresso.

Specifications and Technical Details

Victoria Arduino has managed to pack a ton of power into a relatively compact package, making the E1 Prima a formidable contender in the home espresso arena.

Dimensions and weight

• Width: 41.1 cm
• Height: 37.9 cm
• Depth: 51 cm
• Weight: 37 kg

The E1 Prima may be small, but it’s certainly not lightweight. Ensure you have enough counter space to accommodate this beast.

Boiler specifications

• Boiler system: Dual boiler (1.6L steam boiler, 0.25L coffee boiler)

The boiler for espresso is an energy-saving feature, and it also means you always use fresh, oxygenated water to brew espresso, enhancing the flavour profile.

Temperature stability is 0.3 degrees Celsius thanks to the NEO system and insulation on stainless steel boilers.

Pump type

• Pump type: Internal rotary vane pump

Rotary pumps are known for their quiet operation and consistent pressure, so you can pull shots without waking up the whole house.

Electrical requirements

• Power: 220V-240V Single Phase
• Wattage: Min 1600W / Max 2600W

Due to the NEO system, the machine runs off a 13amp UK plug socket and will only draw energy while you’re brewing/steaming (or when it’s heating up). To put the draw in perspective, a standard kettle will draw 1.2-1.5kW to heat 1 litre of water. While the E1 Prima might be power-hungry, it’s also surprisingly efficient.

Other notable specs include the E1 Prima’s 2-litre water reservoir (with the option to plumb it in), its cool-touch steam wand, and its 58mm portafilter. The steam wand is connected to the machine’s board using Steam By Wire technology (a touchpad), so it is easier to swap the paddle, and there are no mechanical parts to replace it when swapping it out.

The machine also comes with a handy accessory kit, including a tamper, cleaning supplies, and a microfiber cloth to keep that stainless steel exterior looking sharp.

Key Features:

• PID temperature control for both coffee and steam boilers
• NEO (New Engine Optimization) technology for energy efficiency
• Pre-infusion control
• Live pressure visualization
• Volumetric dosing
• Bluetooth connectivity with companion app
• Auto-purge function
• Available in multiple colours/combinations (Shiny, Matt Black, Matt White, Cappellini Red/Blue/Green)

Design and Build Quality

The E1 Prima is a stunner with a sleek, modern design that will turn heads in any kitchen. But as we all know, beauty is more than skin deep.

Materials used

The E1 Prima is crafted from the finest materials, with a stainless steel body built to last. The portafilter and steam wand are also made from stainless steel, ensuring durability and longevity.

The machine’s side panels have various finishes, from classic stainless steel to trendy matte black and white. And let’s not forget about that gorgeous vegan leather portafilter handle; it’s the perfect touch of warmth and sophistication.

Aesthetic considerations

Victoria Arduino has always had a knack for creating machines that are as beautiful as they are functional, and the E1 Prima is no exception. The machine’s clean lines and minimalist design are a testament to Victoria Arduino’s commitment to simplicity and elegance.

One of the standout features of the E1 Prima’s design is its “ghost display.” This innovative display integrates into the machine’s group head, providing shot times during (and after) brewing on shot time. You can set brew temperature and volumetric dosing (on buttons A and C, B is continuous flow) on the group head without going into the app. When the machine is idle, the display disappears completely, blending in with the machine’s sleek exterior.

Footprint and space requirements

As we mentioned earlier, the E1 Prima is a relatively compact machine. But don’t let its small size fool you. This machine still requires a fair amount of counter space. You’ll need to allow for extra room on either side of the machine for easy access to the water reservoir and steam wand. And if you plan on using the E1 Prima’s plumbing kit, you’ll need to factor in additional space for water lines and drainage.

The E1 Prima is a tall machine. If you have low-hanging cabinets or shelves above your countertop, you may need to measure carefully to ensure that the machine will fit comfortably underneath. Remember, good things come in small packages, but great espresso machines sometimes need a bit more room to shine.

Core Functionality

Now that we’ve admired the E1 Prima’s sleek exterior, it’s time to pop the hood and see what this beauty can really do.

Espresso extraction process

At the heart of the E1 Prima is its state-of-the-art espresso extraction system. The machine uses a 58mm group head with an integrated temperature probe, ensuring precise control over the brewing process.

The group head is also equipped with an automatic Soft Infusion System (SIS), which allows for a gentle, even saturation of the coffee grounds before the full extraction begins.

The real magic happens behind the scenes, thanks to Victoria Arduino’s New Engine Optimization (NEO) technology. This innovative system uses a small boiler and a heat exchanger to deliver water to the group head at the perfect temperature with minimal energy waste. The result is a consistently delicious shot of espresso with a rich crema and a complex flavour profile.

Temperature stability data

The machine’s dual boiler system allows for independent control over the brew and steam temperatures, with PID controllers ensuring that each boiler stays within a tight range. According to Victoria Arduino, the E1 Prima’s temperature stability is within +/- 0.5°C, which is pretty impressive.

But temperature stability isn’t just about the boilers; it’s also about the group head. The E1 Prima’s group head is made from a single block of stainless steel, with a built-in heater that keeps the temperature rock-solid throughout the extraction process. This means you can pull shot after shot without worrying about temperature fluctuations or inconsistencies.

Pressure profiling capabilities

Using the machine’s accompanying app, you can create custom pressure profiles for each shot, fine-tuning the extraction to your exact specifications.

The E1 Prima’s pressure profiling system is incredibly intuitive, with a simple drag-and-drop interface that lets you create your profiles in seconds. And if you’re not feeling particularly creative, the app also comes with a range of pre-programmed profiles, each designed to highlight different flavour notes and characteristics in your coffee.

Steam wand performance metrics

The machine’s steam boiler has a capacity of 1.65 litres, which means you can steam milk for days without running out of power. The steam wand is a cool-touch design with a four-hole tip that delivers a powerful, consistent stream of steam.

The E1 Prima’s steam wand is also incredibly easy to use, thanks to its ergonomic design and intuitive controls. The machine’s steam pressure is adjustable, with a range of 0.8 to 3 bar (although Victoria Arduino recommends keeping it at around 2.1 bar for optimal performance). With the machine’s NEO technology, you can steam milk and pull shots at the same time without any loss of pressure or temperature.

User Experience

E1 Prima is a technological marvel, but what’s it like to actually use this machine on a daily basis?

Learning curve

The E1 Prima might not be a machine for beginners. With its advanced features and endless customisation options, it can be a bit intimidating at first glance. The key to success with the E1 Prima is to take things slow and steady. Start by familiarising yourself with the machine’s basic functions. Once you’ve got the basics down, you can start experimenting with the machine’s more advanced features, like pressure profiling and temperature adjustment.

Daily operation workflow

The machine’s intuitive design and user-friendly interface make it easy to pull shots and steam milk with minimal fuss.

One of the biggest advantages of the E1 Prima is its NEO technology, which allows you to brew and steam simultaneously. This means you can prepare your milk while your shot pulls, saving you precious time and effort. And with the machine’s dual boiler system, you never have to worry about running out of steam or compromising temperature stability.

The machine comes with a variety of tools and accessories, including a blind filter basket for backflushing and a steam wand cleaning brush. And thanks to the machine’s automated cleaning cycles and easy-to-remove drip tray, keeping the E1 Prima in tip-top shape is a breeze.

If you want to adjust the pre-infusion time, just open up the app and drag the slider to your desired setting. The E1 Prima’s app has a range of pre-programmed profiles, or you can create your own from scratch.

The E1 Prima also allows you to adjust the brew temperature, steam pressure, and even the colour of the machine’s LED lights. If you’re feeling particularly adventurous, you can even create custom drink recipes and share them with other E1 Prima users around the world.

It’s important to remember that not every tweak or adjustment will necessarily lead to a better shot. It takes time, patience, and a willingness to experiment to master the E1 Prima’s advanced features.

Maintenance and Longevity

Like any espresso machine, the E1 Prima requires regular cleaning to prevent the buildup of coffee oils and residue, which can affect the taste and quality of your shots. 

Regular cleaning requirements

Victoria Arduino has made daily cleaning a breeze with the E1 Prima’s automated cleaning cycles and easy-to-remove components. After each use, it’s important to wipe down the steam wand and purge it of any remaining milk residue. Unless, of course, you’re a fan of sour milk in your next latte. You should also remove the drip tray and rinse it out, as well as wipe down the machine’s exterior with a soft, damp cloth. And don’t forget to empty and rinse the portafilter and basket after each use.

For a deeper clean, the E1 Prima comes with a blind filter basket for backflushing. Simply insert the blind basket into the portafilter, add some cleaning solution, and run the machine’s automated cleaning cycle. Victoria Arduino recommends backflushing the machine at least once a week or more frequently if you’re using it heavily.

Long-term maintenance needs

While daily cleaning is important, it’s not the only maintenance your E1 Prima needs to stay in top form. Like any machine with moving parts and complex electronics, the E1 Prima requires periodic maintenance to prevent wear and tear and keep everything running smoothly. 

Victoria Arduino recommends a 6-month and 12-month service in the first year, both undertaken by an approved VA engineer partner.

One of the most important long-term maintenance tasks is descaling. Over time, mineral buildup from your water supply can accumulate inside the machine’s boilers and pipes, affecting its performance and even causing damage. To prevent this, Victoria Arduino recommends descaling the E1 Prima at least once every 3-4 months or more frequently if you live in an area with hard water. You’ll need to use a descaling solution specifically designed for espresso machines and follow the manufacturer’s instructions carefully. It’s also a good idea to consult your user manual or contact Victoria Arduino’s customer support team if you have any questions or concerns.

Other long-term maintenance tasks include replacing the group head gasket and shower screen as needed, as well as lubricating the machine’s moving parts (such as the steam wand ball joint) to keep them moving smoothly. These tasks should be performed by a qualified technician or a confident DIYer with the proper tools and knowledge.

If plumbed in, the machine should be connected to a correct water filter to protect it from corrosion or scale. Filtered water should also be used when using the tank to ensure the machine’s longevity.

Availability of parts and service

Victoria Arduino has a solid reputation for customer support and parts availability. If you ever need replacement parts for your E1 Prima, you can order them directly from Jaguar Espresso.

Even with the best maintenance and care, there may come a time when your E1 Prima needs more serious repairs. In these cases, it’s important to work with an authorised Victoria Arduino service provider to ensure that your machine is repaired properly and with genuine parts. Victoria Arduino offers a one-year warranty on the E1 Prima.

It is worth noting that if something goes wrong with your machine, your first call should be to the seller and/or an engineering partner, and VA will work with them to solve the issue. 

Proper maintenance and care can significantly extend the life of your E1 Prima and keep it performing at its best for years to come.
