Know before you buy
These burrs are specifically designed for the Eureka Mignon series that utilize a 65mm flat burr set. Please verify your specific Mignon model's burr size before purchasing, as some Mignon variants use smaller 50mm or 55mm burrs.
The BLIND UPPER BURR design is engineered to reduce the amount of coffee grounds trapped inside the grinding chamber. This results in lower retention, meaning you get more of the coffee you put in and less stale grounds in your next shot.
These burrs are specifically optimized for dark roasts and traditional Italian-style espresso. They excel at producing a rich, full-bodied extraction, though they are also capable of handling Turkish and Moka pot grinds.
The cryogenic treatment at -193 °C and the Diamond-Like Carbon (DLC) coating significantly increase the hardness and wear resistance of the steel. This ensures the burrs maintain their sharpness and precision for a much longer lifespan compared to standard stainless steel burrs.
No, these burrs are not dishwasher safe. You should clean them using a dry brush or a specialized grinder cleaning product to avoid damaging the DLC coating or causing rust.
