Eureka’s Open Box Oro Mignon Single Dose Pro brings a workflow-focused update to the original Single Dose design. Optimized for single dosing, the Open Box Single Dose Pro comes packed with features to optimize for faster, low-retention grinding. 65mm espresso-focused burrs, a revised blind upper burr and carrier, and a canted case promise a shorter grind path and minimal grind retention. Further refinements include a 'King Size' grind adjustment knob with rotation indicator for easier grind refinement, A 45-gram single dose hopper with bellows, and a larger hand-brew dosing cup with included spout. Combined, these features create a single dose grinder that excels at grinding for espresso on demand.
