• SEEING DOUBLE?

  The Acaia Umbra is a bold reimagining of the coffee scale—stripped of distractions, yet packed with innovation. Designed for modern espresso bars and high-volume cafés, the Umbra features a sleek, display-free silhouette that blends seamlessly into any setup.

  However, beneath its minimalist exterior lies a powerhouse of precision and connectivity. Using Acaia's patent-pending Magic Relay technology, the Umbra communicates real-time measurement data with other Acaia scales, allowing baristas to switch views effortlessly and maintain a fluid workflow. Built from water-resistant anodized aluminum, it's engineered to withstand the rigors of commercial use while maintaining a low-profile footprint that fits snugly under espresso machines.

  The Umbra's energy-efficient design dramatically reduces power consumption, extending battery life to an impressive 40–48 hours of continuous use, with up to 14 days in standby mode. It connects seamlessly to Acaia's mobile apps, transforming into a standalone smart scale that tracks weight, flow rate, and brew profiles with unmatched accuracy. Powered by Acaia's industrial-grade ReacX weighing technology, the Umbra delivers repeatable precision that professionals rely on. Whether paired with the Pearl or Lunar scales or used solo via smartphone, the Umbra offers unparalleled flexibility, efficiency, and control. It's not just a tool—it's a silent partner in your pursuit of coffee perfection.
