Eureka Costanza R On-Demand Flat Burr Coffee Grinder Chrome

Inconsistent grind size is the silent enemy of great espresso, causing channeling, uneven extraction, and a cup that falls short of the beans' potential. The Eureka Costanza R tackles this head-on with precision flat burrs and stepless micrometric adjustment, giving you the control to unlock every flavour note. Built around a 55 mm hardened steel flat burr set and a robust 310 W motor spinning at 1350 rpm, it delivers uniform grounds for espresso, moka, filter, and French press. The on-demand dosing system with touchscreen lets you program two doses or grind manually, while the ACE System prevents clumping and static for cleaner workflow. An adjustable hands-free fork holds your portafilter securely, and Silent Technology keeps noise to a minimum. Encased in die-cast aluminum with a chrome finish, this grinder is as durable as it is precise.

Who is it for

Home baristas and small café owners who demand repeatable grind quality without the fuss. If you switch between brewing methods or need quick, consistent doses for back-to-back shots, the Costanza R adapts instantly. Its intuitive touchscreen and low-retention design also suit those who value speed and cleanliness in their coffee routine.
