The Eureka Dosing Cup is perfect for those looking for another tool to convert their on demand Mignon grinder into a single dosing setup. Designed for espresso single dosing workflows and fits 58mm portafilters only. Great for weighing your beans with a scale, and catching the grinds as they come out of the grinder before transferring them with a neat flip into your portafilter. Please note that the Dosing Cup is not compatible with standard Eureka portafilter forks.
