The Story
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.
Important Note: An Acaia scale is required for this product to function.
