Eureka Costanza Intelligent Heat-Exchange Espresso Machine

The Smart Heart of Your Home Cafe

The Eureka Costanza is a high-performance prosumer espresso machine designed for those who want professional results without a steep learning curve. At its core is a 1.5-litre insulated stainless steel heat-exchange (HX) boiler, allowing you to brew espresso and steam milk simultaneously. It utilizes a reliable vibration pump and the industry-standard E61 group head, ensuring the thermal stability and passive pre-infusion necessary for café-quality extraction. Its compact, low-profile design is specifically engineered to fit under standard kitchen cabinets while offering a generous workspace for the barista.

What sets the Costanza apart from more traditional machines is its integrated digital brain. It features a sleek OLED display that offers PID temperature control with three distinct presets (90C, 93C and 96C), allowing you to easily adjust for light, medium, or dark roasts. The machine also removes the guesswork from your morning routine with a weekly programmable timer—allowing you to schedule exactly when the machine turns on each day so it's fully heated the moment you walk into the kitchen.⁹ Combined with a built-in shot timer and eco-mode, the Costanza is a smart, robust, and incredibly user-friendly entry into the world of specialty espresso.

Eureka Espresso Machines: Finding Your Perfect Match

For over a century, Eureka has been the silent partner of baristas worldwide, crafting the grinders that define Italian espresso. Now, they’ve finally stepped into the machine world. But with four models that look nearly identical at first glance—Pura, Pura R, Costanza, and Costanza R—how do you know which one belongs on your counter?

The Core DNA: What They All Share

Before we look at the differences, it’s important to know that every machine in this range is built on the same high-performance foundation:

• Heat-Exchange (HX) System: A 1.5L insulated stainless steel boiler that lets you brew and steam at the same time.

• E61 Group Head: The industry icon for thermal stability and that beautiful "passive pre-infusion."

• Rapid Warm-Up: Ready to brew in just 10–15 minutes—significantly faster than most E61 machines.

• Compact Footprint: Designed to fit into modern kitchens without sacrificing power.

Pura vs. Costanza: The "Brain" Difference

The biggest divide in the lineup is the user interface.

• The Pura Series (Analog): Designed for the "purist." There is no digital screen. You manage your shots using the dual-pressure gauge and your own intuition. It’s clean, minimalist, and timeless.

• The Costanza Series (Digital): Designed for the "scientist." It adds a sleek OLED display that provides:

  • 3-Level PID Control: Choose between Warm (90C), Hot (93C), and Very Hot (96C) to match your bean's roast.

  • Shot Timer: Automatically tracks your extraction time.

  • Weekly Scheduler: Program the machine to turn on at specific times each day of the week.

  • Eco Mode & Maintenance: Includes a dose counter and energy-saving modes.

The "R" Factor: Vibration vs. Rotary

You’ll notice two models have an "R" in their name. This stands for Rotary Pump.

• Non-R Models (Pura/Costanza): Use a standard vibration pump. They are reliable and affordable but produce the familiar "buzzing" sound during extraction.

• R Models (Pura R/Costanza R): Use a professional Rotary Pump. This makes the machine whisper-quiet and provides more stable pressure. Furthermore, the "R" models are the only ones that can be plumbed directly into a water line (though they still include a 2L tank).

About Eureka

A Heritage of Italian Excellence and Innovation

Founded in Florence, Italy, in 1920, Eureka has established itself as a global leader in the design and manufacture of high-end coffee grinders. For over a century, the company has combined traditional Italian craftsmanship with cutting-edge technology to serve both the professional barista and the dedicated home enthusiast. Unlike manufacturers that diversify into various appliances, Eureka focuses exclusively on grinding, resulting in a lineup of machines—like the Prometheus and the Atom—that are renowned for their "Silent Technology," stepless precision, and exceptional build quality.

Today, Eureka is synonymous with the "Made in Florence" seal of quality, hand-assembling every unit in their Italian factory. Their philosophy centers on the "Micrometric Adjustment"—a patented system that allows for infinite grind settings by moving the lower burr, ensuring that you never lose your "sweet spot" during cleaning. Whether it’s their IoT-connected commercial giants or the compact Mignon series for the home, Eureka remains the industry gold standard for those who demand a perfect, clump-free grind and a whisper-quiet workflow.
