Product highlights
- The Acaia Umbra Duo is a precision coffee brewing scale with a large weighing platform and app-connected workflow designed for espresso and manual brewing.
- Measure doses and monitor extraction with industrial-grade sensors delivering 0.1g accuracy and real-time data sharing through Acaia connectivity.
- Streamline busy brew bars with a display-free design that sends brewing data to the Acaia app or compatible scales while keeping the platform clean and uncluttered.
Designed for modern brew bars and serious home setups, the Acaia Umbra Duo Coffee Scales are precision brewing scales built to streamline espresso and manual coffee workflows. With a larger weighing platform and industrial-grade sensors, they allow baristas to measure doses, monitor extraction and maintain consistent brewing results across different coffee styles.
Unlike traditional coffee scales, the Umbra Duo uses a display-free design that connects to the Acaia app or compatible Acaia scales. This allows weight and brewing data to appear on paired devices while keeping the scale itself minimal and easy to clean, helping simplify busy coffee preparation workflows.
The expanded platform makes the Umbra Duo particularly useful for portafilter dosing, larger brewers or multi-cup preparations. Combined with high-precision weighing technology and real-time connectivity, it helps maintain accurate brewing ratios and consistent extraction when preparing espresso or filter coffee.
