Italian coffee equipment brand Casadio recently introduced a new flagship grinder, the Ermes Dual, designed for switching back and forth between espresso and filter brew preparation at commercial coffee bars.

Casadio revealed the Ermes Dual last month at the 2025 London Coffee Festival.

As one of the four commercial equipment brands under the Cimbali Group umbrella, Casadio worked closely with Cimbali-owned burr maker Keber Burrs to develop the machine, which centers on a set of vertically oriented 75-millimeter flat steel burrs.

“Ermes Dual is Casadio’s most advanced grinder to date, both in terms of
performance and design philosophy,” Marco Tesconi, global business developer at Keber Burrs, recently told Daily Coffee News. “It represents a significant step up for the brand, positioning itself in a more premium space than previous models, and is aimed not just at traditional espresso bars, but also at more flexible, hybrid brewing environments.”

Its functional duality comes by way of a burr gap detection system that reports the burrs’ separation in real time, in microns. Through a 2.5-inch TFT color display, baristas can program and recall up to five grinding profiles, including time and burr gap settings.

“Each of the five stored grind profiles saves the precise micron distance between burrs, and the user interface displays that value clearly,” Tesconi said. “This gives baristas a digital reference point for each brewing method, whether espresso, V60 or Chemex, so they can return to the exact grind size without guesswork. It’s a smart blend of manual control and digital memory for baristas who switch brewing styles throughout the day.”

Founded in 1950 in Bologna, Casadio became part of the Cimbali Group in 2009. The Group acquired Keber in 2017.

Christopher Flechtner, whose industrial design work includes iconic machines made by Slayer — which was also acquired by Cimbali Group in late 2017 — contributed to the aesthetic and material choices of the Ermes Dual, including its textured surfaces, exposed screws and a transparent column at the base of the hopper where beans enter the chamber.

The Ermes Dual outputs up to 3 grams per second to keep pace with high-volume commercial coffee service. Its hopper holds 550 grams (19.4 ounces) of whole beans, and a portafilter holder allows for hands-free on-demand grinding.

The machine’s aluminum exterior is available in either black or white, and its anticipated retail price is set at $2,565. Shipping to customers in the U.S. and Europe is scheduled to begin next month.

“Casadio is moving into the premium, multipurpose brewing space,” Tesconi said. “This grinder isn’t just an evolution of existing products; it’s a repositioning of the brand to serve coffee professionals who value both form and function.”
