Two Souls, One Grinder.
Designed for modern extraction standards, the Burrs 02 architecture delivers a narrow, highly uniform particle distribution with a controlled presence of fines. This precision results in a brew that is exceptionally balanced, offering a syrupy, smooth mouthfeel with maximized sweetness. By taming sharp acidity while boosting body, perfect for unlocking the complex potential of Light Roast Specialty Beans.
Engineered for high-definition flavor, the Burrs 01 architecture produces a wide particle distribution with absolute minimal fines. This specific geometry reduces muddy flavors, delivering a cup characterized by intense clarity, bright acidity, and a crisp finish. It effectively cuts through the heaviness of oils, making it the definitive choice for brewing Medium to Dark Roasts where a clean mouthfeel is paramount.
The coffee powder samples submitted for testing were ground from small-batch product samples, analyzed using the German Microtrac MRB CAMSIZER X2 model, which employs dynamic image analysis for particle size and shape distribution.
