Fiorenzato Adds Ring Nut and ‘Ada’ Connection to All New Grinders

Italian coffee grinder maker Fiorenzato recently rolled out two features it is adding to all new machines: a connected platform called Ada, and a manual grind adjustment system with a new RSG Ring Nut.

Both new features were unveiled at the 2025 HostMilano expo in Milan (read all of DCN’s HostMilano 2025 coverage).

Fiorenzato Ada

Ada enables real-time communication between the grinder and any compatible wired espresso machine. The system reads data from espresso machines’ flow meters while also tracking ambient temperature and humidity.

A burr distance detection system in Ada-equipped grinders rounds out the data needed to calculate and display a new suggested grind setting. The barista can manually adjust to continue hitting a prescribed recipe.

“The grinder processes data from the machine’s flowmeter via integrated software. In this way, it learns, adapts and suggests the perfect grind in real time,” the company said in an announcement of the launch. “The result is an intelligent and reliable system that supports the barista like a true digital assistant.”

The system’s name refers to the adaptive nature of its function and to 19th-century mathematician Ada Lovelace, who is often credited as the first computer programmer.

“[Lovelace was] a pioneer of programming and a symbolic figure of vision, precision and technological creativity,” a Fiorenzato representative told Daily Coffee News. “It is a tribute to the history of innovation that aligns with the direction we are charting in the digital field.”

Fiorenzato RSG Ring Nut

The RSG Ring Nut — which stands for “Ready, Set, Grind” — is an adjustment collar upgrade Fiorenzato developed based on positive feedback from users of its AllGround product line.

The Ring Nut’s silicone edge enhances grip while smoother ring mobility improves ease of use. Audible spring-loaded clicks reinforce the barista’s awareness of incremental adjustments while keeping eyes on the grinder’s Ada-enabled display. The nut’s position locks with a push-button mechanism similar to a retractable pen.

The display shows the recommended setting with color-coding, locking in on green when the target is met. 

“Long considered one of the most delicate gestures in the work process, grind adjustment now becomes immediate,” Fiorenzato said. “With RSG, it takes just a few seconds to find the perfect point.”

Neither the ring nuts nor Ada will be retrofittable to older grinder models. Grinders equipped with the RSG and Ada features are scheduled to begin shipping by summer. The company said prices of machines will not change based on the features.
